LONG ESSAYS

Q1. Meniere's Disease (Endolymphatic Hydrops)

a. Diagnosis

A 55-year-old male with acute vertigo (episodic, lasting minutes to hours), right-sided ear block (aural fullness), tinnitus, and fluctuating sensorineural hearing loss = Meniere's Disease
Diagnostic criteria (AAO-HNS):
  • Two or more spontaneous episodes of vertigo each lasting 20 min - 12 hours
  • Audiometrically documented low-to-mid frequency SNHL on at least one occasion
  • Fluctuating aural symptoms (hearing loss, tinnitus, fullness) in the affected ear
  • Not better accounted for by another vestibular diagnosis

b. Aetiopathogenesis

The underlying pathology is endolymphatic hydrops - excess accumulation of endolymph in the membranous labyrinth.
Causes/theories:
  1. Malabsorption theory - decreased reabsorption of endolymph by the endolymphatic sac (commonest accepted theory)
  2. Hypersecretion theory - overproduction by stria vascularis
  3. Obstruction theory - obstruction of endolymphatic duct by fibrosis/bone anomaly
  4. Immune-mediated - autoimmune endolymphatic hydrops
  5. Viral - past viral infection of endolymphatic sac
  6. Allergy/vascular - associated with allergy, migraine, hypothyroidism
Mechanism of attacks: When endolymph pressure rises, the Reissner's membrane ruptures, mixing endolymph (high K+) with perilymph (low K+) - this causes potassium intoxication of the 8th nerve, producing acute attack. The membrane heals and the cycle repeats.

c. Investigations

Audiological:
  • Pure Tone Audiometry (PTA): Low-frequency SNHL initially; carhart notch absent (unlike otosclerosis). Hearing fluctuates.
  • Speech Discrimination Score (SDS): Reduced
  • SISI (Short Increment Sensitivity Index): High (positive recruitment = cochlear pathology)
  • Tone Decay Test: Negative (no retrocochlear involvement)
  • Impedance audiometry: Type A tympanogram; absent acoustic reflexes if significant SNHL
Vestibular tests:
  • Electronystagmography (ENG)/Videonystagmography (VNG): May show reduced caloric response (canal paresis) on affected side
  • Vestibular Evoked Myogenic Potentials (VEMP): Reduced amplitude on affected side
Special tests:
  • Electrocochleography (ECochG): SP/AP ratio >0.45 is diagnostic of hydrops (most specific test)
  • Glycerol test (Dehydration test): Oral glycerol 1.5 g/kg given; if PTA improves by ≥10 dB or SDS improves by ≥12% after 2-3 hours = positive (confirms hydrops)
  • MRI with gadolinium (Gadolinium-enhanced MRI): To rule out acoustic neuroma; VEMP and ECochG are functional tests
  • MRI of posterior fossa: Rule out cerebellopontine angle tumor

d. Treatment

Medical (mainstay):
  1. Salt restriction (<1.5 g/day) and fluid intake 2L/day
  2. Diuretics: Acetazolamide 250 mg BD or hydrochlorothiazide + amiloride - reduce endolymph volume
  3. Vestibular sedatives during acute attack:
    • Prochlorperazine (Stemetil) - IM/oral
    • Diazepam
  4. Betahistine (Serc): 8-16 mg TDS - improves microcirculation in cochlea; reduces frequency of attacks
  5. Antihistaminics: Cinnarizine, meclizine
  6. Low-dose steroids - for immune-mediated cases
Intratympanic therapy:
  • IT Gentamicin: Chemical labyrinthectomy - ablates vestibular function; preserves hearing
  • IT Dexamethasone: Preserves both hearing and vestibular function; fewer side effects; multiple sessions needed
Surgical (for refractory cases):
  • Endolymphatic sac surgery (decompression/shunt): Least destructive; good vertigo control; preserves hearing
  • Vestibular neurectomy: Sectioning of vestibular nerve; preserves hearing; best vertigo control
  • Labyrinthectomy: Only when hearing is non-functional; complete vertigo control

Q2. Male Child 3 yrs - Noisy Breathing 1 Day, URTI 3 Days, High Fever, Pain on Swallowing. X-ray: Thumb Sign

a. Most Likely Diagnosis: Acute Epiglottitis

b. Define Stridor

Stridor is a harsh, high-pitched, noisy breathing produced due to turbulent airflow through a partially obstructed larynx or trachea. It is a sign, not a diagnosis.
Types:
  • Inspiratory stridor: Obstruction at or above glottis (supraglottic/glottic) - e.g., epiglottitis, croup
  • Expiratory stridor: Intrathoracic tracheal or bronchial obstruction
  • Biphasic stridor: Subglottic or tracheal obstruction (both phases)
Acute epiglottitis causes inspiratory stridor.

c. Two Causes of Stridor

In children:
  1. Acute epiglottitis (Haemophilus influenzae type b) - supraglottic obstruction
  2. Acute laryngotracheobronchitis (Croup) (Parainfluenza virus) - subglottic obstruction
Other causes: Foreign body, laryngomalacia, subglottic stenosis, diphtheria, angioedema

d. Treatment of Acute Epiglottitis

EMERGENCY - Do NOT examine throat with tongue depressor (may cause complete obstruction)
Immediate airway management:
  • Keep child calm; allow to sit upright (sniffing position)
  • Oxygen by face mask
  • Do NOT force patient to lie down
  • Prepare for emergency intubation/tracheostomy
  • Nasotracheal intubation by experienced anaesthetist in OT under controlled conditions (preferred over orotracheal)
  • Tracheostomy if intubation fails
Antibiotics:
  • IV Cefuroxime or Ceftriaxone - covers H. influenzae
  • Chloramphenicol if beta-lactam allergy
Steroids:
  • IV Dexamethasone - reduces airway edema
Supportive:
  • IV fluids (child cannot swallow)
  • Humidified oxygen
  • Adrenaline nebulization for edema reduction
Prevention: Hib vaccine (given as part of immunization - "child was immunized" in question but epiglottitis still occurred possibly due to incomplete schedule or non-b serotype)
X-ray neck (lateral): Shows Thumb sign = swollen epiglottis resembling a thumb (pathognomonic). Normal epiglottis looks like a little finger.

Q3. Female 30 yrs - Loss of Smell, Nasal Obstruction, Foul Smell, Excessive Nasal Crusting, Social Stigma

a. Diagnosis: Primary Atrophic Rhinitis (Ozaena)

b. Aetiopathogenesis

Primary Atrophic Rhinitis is a chronic disease of the nose characterized by progressive atrophy of the nasal mucosa and underlying turbinate bones.
Theories:
  1. Infective theory (Klebsiella ozaenae) - most accepted
    • Klebsiella ozaenae is isolated in most cases
    • Other organisms: Coccobacillus foetidus, Diphtheroids, Proteus
  2. Endocrine theory:
    • Common in young females (hormonal influence)
    • Appears at puberty, improves after pregnancy/menopause
    • Oestrogen deficiency affects mucous membrane nutrition
  3. Nutritional deficiency:
    • Deficiency of iron, vitamin A, vitamin D, calcium
    • Leads to mucosal atrophy and bone resorption
  4. Autonomic imbalance:
    • Sympathetic overactivity causes vasoconstriction
    • Leads to mucosal ischemia and atrophy
  5. Autoimmune theory:
    • Elevated serum IgG, IgA levels found in some patients
  6. Racial/hereditary: More common in Asians; familial tendency
Pathology: Ciliated columnar epithelium - squamous metaplasia. Mucosal glands atrophy. Endarteritis and periarteritis obliterans. Turbinates undergo osteoclastic resorption. Nasal cavity becomes wide (paradoxically obstructed due to lack of nasal airflow sensation).

c. Management

Medical (initial):
  1. Nasal irrigation with normal saline or alkaline nasal douche (sodium bicarbonate + sodium chloride + sodium biborate) - removes crusts, freshens mucosa
  2. 25% glucose in glycerine nasal drops - inhibits proteolytic organisms
  3. Oestrogen spray - increases vascularity
  4. Antibiotics: Based on culture; Ciprofloxacin for Klebsiella
  5. Vitamin A + D, iron supplementation
  6. Potassium iodide orally - stimulates mucosal secretion
Surgical:
  1. Young's operation - complete closure of both nostrils with mucoperiosteal flaps; prevents airflow, allows mucosa to recover (3 months); then reopened (modified Young's - one nostril closed)
  2. Submucosal injection of Teflon/paraffin - narrows nasal cavity
  3. Transposition of parotid duct (Stensen's duct) into maxillary sinus - provides moisture
  4. Tissue implants under lateral wall - narrowing of cavity (cartilage, bone, fat)

SHORT ESSAYS

Q4. Rhinocerebral Mucormycosis

Causative organisms: Rhizopus, Mucor, Absidia (class Zygomycetes/Mucorales)
Predisposing factors:
  • Diabetics (especially with ketoacidosis) - MC association
  • Immunocompromised (chemotherapy, steroid use, HIV)
  • Renal failure, malnutrition
Clinical Features:
  • Stage 1 - Nasal: Nasal congestion, bloodstained discharge, black crusts (eschar) in nose/palate - pathognomonic
  • Stage 2 - Sinus: Fever, facial pain, orbital cellulitis
  • Stage 3 - Orbital: Proptosis, ophthalmoplegia, chemosis, loss of vision (orbital apex syndrome)
  • Stage 4 - Cerebral: Cavernous sinus thrombosis, cerebral infarction (thrombosis of vessels by fungal hyphae), coma, death
Mechanism: Fungal hyphae invade blood vessel walls causing thrombosis and tissue infarction - produces characteristic black necrotic eschar.
Diagnosis:
  • KOH mount of nasal scraping: shows broad, non-septate, right-angled (90°) branching hyphae
  • Biopsy: Hyphae invading vessel walls
  • CT/MRI: Bony erosion, orbital and cranial involvement
  • Blood glucose, ABG (acidosis)
Treatment:
  1. Control underlying condition - correct acidosis, normalize glucose
  2. Systemic Amphotericin B (drug of choice) - 1-1.5 mg/kg/day IV; liposomal form less nephrotoxic
  3. Posaconazole/Isavuconazole - alternative/salvage therapy
  4. Surgical debridement - aggressive removal of all necrotic tissue; maxillectomy, orbital exenteration if needed
  5. Prognosis: Poor if cerebral involvement; mortality >50% in advanced disease

Q5. Vocal Rehabilitation Following Total Laryngectomy

After total laryngectomy, the patient loses the larynx - hence no phonation and no connection between trachea and pharynx. Rehabilitation options:

1. Oesophageal Voice (Oesophageal Speech)

  • Patient learns to inject/swallow air into oesophagus and expel it to vibrate the pharyngo-oesophageal (PE) segment
  • Natural; no device needed
  • Requires intensive training (weeks to months)
  • Quality: low pitch, limited volume, staccato speech
  • Success rate: ~30%

2. Tracheo-oesophageal Puncture (TEP) - Most Popular

  • A surgically created fistula between the posterior tracheal wall and anterior oesophageal wall
  • A Blom-Singer prosthesis (one-way voice prosthesis valve) is inserted
  • Patient occludes the stoma with a finger/thumb, air from lungs passes through valve into oesophagus, vibrates PE segment
  • Excellent voice quality; most natural-sounding
  • Can be done at time of laryngectomy (primary) or later (secondary)
  • Complication: Aspiration through valve, candidal colonization, voice prosthesis dislodgment

3. Electrolarynx (Artificial Larynx)

  • Battery-operated vibrating device held against the neck or placed in the mouth
  • Vibration transmitted to pharynx - produces robotic/electronic sound
  • Easiest to learn; immediate use post-op
  • Drawback: Robotic voice quality; hands not free

4. Neck Dissection + Surgical Shunts (historical) - Largely abandoned

Summary Table:
MethodDeviceVoice QualityEaseHands-free
OesophagealNoneFairDifficultYes
TEP (Blom-Singer)ValveBestModerateNo (must occlude stoma)
ElectrolarynxMachineRoboticEasyNo

Complications

Minor:
  • Synechiae (adhesions) - MC complication
  • Haemorrhage
  • Infection
  • Recurrence of polyposis
Major:
  • Orbital: Medial wall (lamina papyracea) breach - orbital haematoma, diplopia, blindness (optic nerve injury)
  • Vascular: Anterior ethmoidal artery injury - orbital haematoma
  • CSF leak: Cribriform plate injury - meningitis risk
  • Intracranial: Meningitis, brain abscess (rare)
  • Nasolacrimal duct injury: Epiphora

Q7. Applied Anatomy of Retropharyngeal Space + Acute Retropharyngeal Abscess

Applied Anatomy of Retropharyngeal Space

Boundaries:
  • Anterior: Posterior wall of pharynx (buccopharyngeal fascia)
  • Posterior: Prevertebral fascia (alar layer of prevertebral fascia)
  • Lateral: Carotid sheaths on each side
  • Superior: Base of skull
  • Inferior: Upper mediastinum (at T1-T2 level where alar and prevertebral fascia fuse)
Contents:
  • Loose areolar tissue
  • Retropharyngeal lymph nodes of Rouviere (2 nodes on each side of midline) - present in children, involute by age 4-6 years
  • Fat
Clinical importance:
  • Midline raphe divides space into 2 compartments (explains unilateral bulge in abscess)
  • Communicates with parapharyngeal space laterally
  • Danger space (between alar and prevertebral fascia) extends to posterior mediastinum - risk of descending necrotizing mediastinitis

Acute Retropharyngeal Abscess

Aetiology:
  • Suppuration of retropharyngeal lymph nodes following URTI, pharyngitis, tonsillitis
  • Common in children <4 years (nodes present)
  • Organisms: Streptococcus, Staphylococcus, anaerobes
Clinical features:
  • Fever, rigors, toxemia
  • Dysphagia - difficulty/pain on swallowing
  • Muffled/hot potato voice
  • Neck stiffness - "cock robin" position (neck extended, head turned to one side)
  • Stridor - if larynx compressed
  • Bulging of posterior pharyngeal wall (unilateral, lateral to midline)
  • Drooling of saliva
Investigations:
  • X-ray soft tissue neck lateral view: Increased prevertebral soft tissue shadow (>7 mm at C2, >14 mm at C6 in adults; >40% of vertebral body width); loss of cervical lordosis
  • CT neck with contrast: Hypodense collection with ring enhancement; extent of abscess
  • Bloods: TLC raised, neutrophilia
Treatment:
  • Hospitalization, IV antibiotics (Penicillin + Metronidazole, or Ampicillin-Sulbactam)
  • Incision and drainage: Transoral approach with patient in Rose position (head low/tonsil position) to prevent aspiration; incision made in most prominent part of bulge; suction immediately available
  • If extends to mediastinum: Transcervical drainage or thoracotomy
Complications:
  • Aspiration of pus - asphyxia
  • Descending necrotizing mediastinitis
  • Spontaneous rupture into airway
  • Jugular vein thrombosis
  • Meningitis

Q8. Cholesteatoma - Classification and Theories of Formation

Classification

A. Congenital Cholesteatoma:
  • Present from birth; no history of ear discharge or perforation
  • Found behind intact tympanic membrane (anterosuperior quadrant)
  • Arises from ectodermal rests (epithelial cell nests - "epidermoid formation" of Teed)
B. Acquired Cholesteatoma:
  1. Primary Acquired Cholesteatoma:
    • No previous history of otitis media or perforation
    • Arises from retraction pocket in the pars flaccida (Shrapnell's membrane) of the tympanic membrane
    • Located in the attic/epitympanum
    • Associated with Eustachian tube dysfunction
  2. Secondary Acquired Cholesteatoma:
    • Follows chronic suppurative otitis media (CSOM) with marginal/attic perforation
    • Squamous epithelium migrates through the perforation into the middle ear

Theories of Formation

  1. Invagination theory (Wittmaack) - Most Accepted
    • Negative middle ear pressure (due to Eustachian tube dysfunction)
    • Creates retraction pocket in pars flaccida
    • Pocket deepens progressively
    • Desquamated keratin accumulates - forms cholesteatoma
  2. Metaplasia theory (Sade)
    • Chronic inflammation causes metaplasia of middle ear mucosa
    • Cuboidal/columnar epithelium undergoes squamous metaplasia
    • Keratin accumulates
  3. Epithelial migration theory (Habermann, Bezold)
    • Squamous epithelium of external canal migrates through a perforation
    • Particularly marginal perforations allow ingrowth of squamous epithelium
  4. Basal cell hyperplasia theory (Ruedi)
    • Basal cells of Shrapnell's membrane proliferate under stimulation of chronic inflammation
    • Form keratinizing epithelium within middle ear
Structure of cholesteatoma:
  • Outer matrix (keratinizing squamous epithelium)
  • Keratin debris (dead squames) in the centre
  • Perimatrix (fibrous layer)
  • Produces collagenases, cytokines (IL-1, TNF) - cause bone erosion

Q9. Extra-cranial Complications of Sinusitis

(Also called: Extra-nasal / Orbital and facial complications)

Orbital Complications (Chandler's Classification - MC group of complications)

StageNameFeatures
IInflammatory oedema (preseptal cellulitis)Oedema of eyelids; no proptosis, normal vision
IIOrbital cellulitisOedema of orbital fat; mild proptosis; EOM intact
IIISubperiosteal abscessPus between periorbita and orbital wall; proptosis + displacement of globe
IVOrbital abscessPus within orbital fat; severe proptosis, ophthalmoplegia, chemosis
VCavernous sinus thrombosisBilateral proptosis, high fever, septicemia - this is intracranial
Most common complication = Orbital cellulitis (from ethmoid sinusitis)
Management:
  • Stages I, II: IV antibiotics (Cefuroxime/Ceftriaxone); CT orbit to monitor
  • Stage III: IV antibiotics + surgical drainage
  • Stages IV, V: Urgent surgical drainage (FESS or external approach) + IV antibiotics

Osseous Complications

  1. Pott's Puffy Tumour:
    • Osteomyelitis of frontal bone with subperiosteal abscess
    • Doughy swelling over forehead; tender
    • Complication of frontal sinusitis
    • Treatment: IV antibiotics + surgical drainage + sinus obliteration
  2. Osteomyelitis of maxilla

Facial Complications

  • Facial cellulitis/oedema
  • Oro-antral fistula (from maxillary sinusitis)

Q10. An Elderly Diabetic with Deep-seated Gnawing Ear Pain, Worse at Night, Granulation in External Auditory Canal

a. Diagnosis: Malignant (Necrotising) Otitis Externa

b. Common Microbial Organisms

  • Pseudomonas aeruginosa - by far the most common (>95%)
  • Staphylococcus aureus (less common)
  • Aspergillus (in immunocompromised, non-diabetic)

c. Treatment Modalities

Principles: This is a serious, potentially fatal infection. Aggressive treatment required.
Medical:
  1. IV anti-pseudomonal antibiotics (drug of choice):
    • Ciprofloxacin (oral/IV) - first line; excellent bioavailability
    • Piperacillin-tazobactam + aminoglycoside
    • Ceftazidime
    • Duration: minimum 6-8 weeks
  2. Control of diabetes: Tight glycaemic control is essential for response to treatment
  3. Topical antibiotics + aural toilet: Ciprofloxacin drops; gentle debridement
  4. Hyperbaric oxygen therapy: Adjunct; improves tissue oxygenation; useful in refractory cases
Surgical:
  • Debridement of granulation tissue and necrotic bone in EAC
  • If osteomyelitis of temporal bone/skull base: Mastoidectomy, partial temporal bone resection
  • Surgery is conservative - aim to debride, not radical resection
Monitoring response:
  • Gallium-67 scan or SPECT: Monitors response to treatment better than CT
  • ESR/CRP normalization
  • Clinical improvement (pain relief)

SHORT ANSWERS (10 x 3 = 30 Marks)

11. Fistula Test

A test to detect perilymph fistula or erosion of the lateral semicircular canal (by cholesteatoma).
Method: External auditory canal is compressed (by Siegel's speculum, tympanometer, or finger) to increase or decrease pressure in the EAC.
Positive test: Pressure change causes nystagmus and vertigo (Hennebert's sign/Tullio phenomenon). Eyes deviate toward the compressed ear on compression, with nystagmus beating away.
Types:
  • True positive: Cholesteatoma eroding semicircular canal with intact membrane (fistula but labyrinth still functional) - nystagmus + vertigo
  • False positive: Congenital syphilis (Hennebert's sign) - nystagmus with intact labyrinth
  • Negative fistula test: Labyrinthine fistula BUT dead labyrinth - no response
Clinical significance: Positive fistula test in CSOM with cholesteatoma = lateral SCC fistula until proven otherwise; modify surgical plan.

12. Water's View X-ray

Also called Occipito-mental view or Paranasal sinus X-ray.
Position: Patient faces the cassette, chin extended until orbito-meatal line makes 45° angle with the film. Central ray passes through the middle of the occipital bone.
Structures visualized:
  • Maxillary sinuses (best visualized - both sinuses)
  • Frontal sinuses
  • Ethmoid sinuses
  • Orbit (including orbital floor for blowout fracture)
  • Nasal bones
  • Zygomatic arches
Uses:
  • Maxillary sinusitis (air-fluid level, opacity, mucosal thickening)
  • Maxillary tumours
  • Orbital blow-out fracture ("trapdoor" or "hanging drop" sign - herniation of orbital fat into maxillary antrum)
  • Zygomatic fractures (tripod fracture)
  • Nasal polyps causing antral opacification

13. Cavernous Sinus Thrombosis (CST)

Definition: Septic thrombosis of the cavernous sinus, an intracranial complication of sinusitis or facial/ear infections.
Source of infection:
  • Sphenoidal sinusitis - most direct route
  • Ethmoidal sinusitis
  • Frontal sinusitis via superior ophthalmic vein
  • Furuncle of nose/upper lip (danger triangle of face) - via facial vein
Clinical features:
  • High fever, rigors, toxemia
  • Severe headache
  • Proptosis - bilateral (distinguishes from orbital cellulitis which is unilateral initially)
  • Chemosis (conjunctival oedema)
  • Ophthalmoplegia - 3rd, 4th, 6th nerve palsies (all pass through cavernous sinus)
  • Periorbital oedema
  • V1, V2 involvement - forehead/cheek anaesthesia
  • Papilloedema, decreased visual acuity
  • Meningism
Investigations:
  • CT/MRI with contrast: "Empty delta sign" if superior sagittal sinus involved; enlargement of cavernous sinus, irregularity
  • MR venography: Gold standard
  • Blood cultures (positive in 70%)
  • Lumbar puncture (if meningitis suspected)
Treatment:
  • High-dose IV antibiotics (Ceftriaxone + Metronidazole + Vancomycin)
  • Anticoagulation (heparin) - controversial but used
  • Treat primary focus (sphenoid sinus drainage)
  • Steroids (to reduce inflammation)

14. Fracture Nasal Bones

Commonest facial bone to fracture (due to prominent position).
Types:
  • Unilateral/bilateral depression
  • Open book fracture - bilateral lateral displacement
  • Comminuted
Clinical features:
  • Epistaxis
  • External deformity (swelling, deviation)
  • Tenderness, crepitus over nasal dorsum
  • Nasal obstruction
  • Septal haematoma - boggy, bluish, bilateral swelling of septum (must be drained immediately to prevent avascular necrosis and saddle nose)
Investigations:
  • X-ray nasal bones (lateral view): Shows fracture line
  • CT face: Better delineation; needed if associated midface fractures suspected
Treatment:
  • Timing: Immediate (within 2-3 hours) or delayed (7-10 days after swelling subsides)
  • Closed reduction under LA or GA: Walsham's forceps (for displaced fragment) + Asch's forceps (for septal displacement)
  • External splint for 10 days
  • If delayed >14 days: Wait 6 months, then septorhinoplasty
  • Drain septal haematoma immediately

15. Unpaired Cartilages of the Larynx

The laryngeal cartilages are 9 in total: 3 unpaired + 3 paired.
Unpaired (single, midline) cartilages:
  1. Thyroid cartilage:
    • Largest cartilage; hyaline cartilage
    • Two laminae meeting at 90° (male) or 120° (female) - Adam's apple more prominent in males
    • Laryngeal prominence (Adam's apple)
    • Superior and inferior horns (cornua)
    • Cricothyroid joint: Rotation and gliding movements
  2. Cricoid cartilage:
    • Only complete ring in the airway
    • Signet ring shape - narrow arch anteriorly, broad quadrate lamina posteriorly
    • Hyaline cartilage
    • Only laryngeal cartilage that encircles the airway completely
  3. Epiglottis:
    • Leaf-shaped; elastic fibrocartilage (does NOT calcify)
    • Attached to thyroid cartilage by thyroepiglottic ligament
    • Petiolus = lower stalk that attaches to thyroid notch
    • Separates laryngeal inlet from laryngopharynx during swallowing
Paired (bilateral) cartilages: Arytenoid, Corniculate (Santorini), Cuneiform (Wrisberg)

16. Secondary Acquired Cholesteatoma

Definition: Cholesteatoma arising secondary to chronic suppurative otitis media, where squamous epithelium gains access to the middle ear through a perforation or erosion of the tympanic membrane.
Pathogenesis:
  • A marginal or attic (pars flaccida) perforation in CSOM allows squamous epithelium from the EAC to migrate into the middle ear
  • Epithelial migration (Habermann's theory) occurs along the path of least resistance
  • The migrated stratified squamous epithelium retains its property of desquamating keratin
  • Keratin accumulates progressively in an enclosed space = forms a sac
Features distinguishing from primary acquired:
  • History of chronic ear discharge preceding diagnosis
  • Perforation visible (marginal or pars flaccida)
  • May have larger cholesteatoma at presentation (later presentation)
Complications from bone erosion:
  • Ossicular chain destruction - conductive hearing loss
  • Lateral semicircular canal fistula
  • Facial nerve dehiscence - facial palsy
  • Tegmen plate erosion - meningitis, brain abscess
  • Sinus plate erosion - lateral sinus thrombophlebitis

17. Pure Tone Audiometry (PTA) and Impedance Audiometry in Otosclerosis

Pure Tone Audiometry Findings in Otosclerosis:

  • Type: Conductive hearing loss (CHL) - initially; mixed if cochlea involved
  • Air-bone gap: Present; typically 30-60 dB
  • Bone conduction: Near normal but shows characteristic dip at 2000 Hz = Carhart's notch (2 kHz notch of ~5 dB at 500 Hz, ~10 dB at 1000 Hz, ~15 dB at 2000 Hz, ~5 dB at 4000 Hz) - a mechanical artifact, not true SNHL
  • Air conduction: Elevated, especially at low frequencies
  • Speech audiometry: Good speech discrimination (pure CHL)
  • In cochlear otosclerosis (histological otosclerosis): Mixed or SNHL; poor SDS

Impedance Audiometry (Tympanometry + Acoustic Reflexes):

  • Tympanogram: Type As (shallow) - reduced compliance/compliance peak; flat curve with reduced peak height. (Type As = Stiffness dominant)
    • Note: Not Type B (which is flat, as in effusion)
  • Acoustic reflex: Absent (ipsilateral and contralateral) - stapedius muscle attached to a fixed stapes cannot contract
  • Special finding: In early otosclerosis - "On-off effect" (biphasic reflex) - initial positive deflection (stiffness) followed by negative; then disappears as fixation progresses

18. Eagle's Syndrome

Definition: Symptomatic elongation of the styloid process or calcification of the stylohyoid ligament.
Normal styloid process: 2.5-3 cm long. Eagle's syndrome when >3 cm (some say >2.5 cm).
Two types:
  1. Classic Eagle's syndrome:
    • Following tonsillectomy/trauma
    • Persistent sore throat, dysphagia, foreign body sensation in the throat
    • Pain referred to the ear (otalgia - via Jacobson's nerve/Arnold's nerve)
    • On palpation: Tender tip palpable in the tonsillar fossa
  2. Stylocarotid syndrome:
    • Elongated styloid presses on internal carotid artery
    • Unilateral headache, orbital pain, neck pain
    • Syncope, TIA (from carotid compression)
Diagnosis:
  • OPG (orthopantomogram) or CT: Shows elongated styloid
  • Diagnostic test: Pain relief with injection of local anaesthetic in tonsillar fossa (procaine injection)
Treatment:
  • Transoral or external cervical styloidectomy (shortening of styloid process)
  • NSAIDS, steroids for mild cases

19. Acute Necrotising Otitis Media (ANOM)

Definition: A severe, rapidly progressive form of acute otitis media with massive destruction of the tympanic membrane and middle ear structures due to necrotizing infection.
Aetiology:
  • Occurs during or after exanthematous fevers: Measles, Scarlet fever, Diphtheria, Influenza
  • Organisms: Streptococcus pyogenes (group A beta-haemolytic Strep), Staphylococcus
  • Associated with poor immunity/malnutrition
Pathology:
  • Sudden rupture of entire TM (large, ragged perforation or total TM destruction)
  • Necrosis of ossicles, mastoid mucosa
  • Rapidly progressing
Clinical features:
  • Occurs during acute febrile illness
  • Sudden, profuse, blood-stained ear discharge
  • Severe otalgia
  • Large central perforation (may involve entire TM)
  • Hearing loss (conductive)
Treatment:
  • IV antibiotics (Penicillin, Amoxicillin-clavulanate)
  • Aural toilet
  • Myringoplasty later for TM repair
  • Mastoidectomy if mastoiditis develops
Prognosis: Can lead to permanent perforation, ossicular damage, and long-standing conductive hearing loss.

20. Lupus Vulgaris

Definition: The most common form of cutaneous tuberculosis affecting the head and neck region, including the nose and skin.
Causative agent: Mycobacterium tuberculosis (occasionally BCG vaccination)
Pathology: Tuberculoid granuloma in the dermis - giant cells, epithelioid cells, caseation (minimal)
Nasal involvement:
  • Affects the nasal vestibule and nasal mucosa (most common site on face = nose/nasolabial fold)
  • Soft, reddish-brown papules/nodules - show apple-jelly nodules on diascopy (glass slide pressed on skin reveals brownish-yellow translucent nodule) - pathognomonic
  • Progressive ulceration and scarring
  • Heals with scarring and keloid formation
  • May cause nasal destruction, saddle nose deformity
Clinical features:
  • Slow, progressive, painless lesion
  • Apple-jelly nodules on diascopy
  • Scar formation in healed areas with new lesions at periphery
  • May cause ectropion, alar collapse, nasal septal perforation
Diagnosis:
  • Biopsy: Tuberculoid granuloma
  • Mantoux test: Strongly positive
  • Culture: M. tuberculosis (may be negative as paucibacillary)
  • PCR for MTB DNA
Treatment:
  • Standard anti-tubercular therapy (ATT): HRZE for 2 months, then HR for 4 months (total 6 months)
  • Surgical reconstruction of nasal defects after disease control
