Hemangioma of the Left Oral Mucosa

Definition & Overview

• Cummings Otolaryngology Head and Neck Surgery, Ch. 90

Classification

Epidemiology & Site Predilection

• Infantile hemangiomas occur in up to 10% of all births; female predominance
• The lip is the most frequent site of hemangioma in the oral cavity, followed by tongue, buccal mucosa, and floor of mouth
• Usually present at birth or become evident in the first few weeks/months of life; can occasionally become evident later

Associated Syndromes

• Sturge-Weber-Dimitri syndrome (facial port-wine stain, leptomeningeal angiomatosis, glaucoma)
• Von Hippel-Lindau syndrome (hemangioblastomas + visceral lesions)
• Multiple cutaneous lesions are not uncommon alongside parotid/salivary gland hemangiomas

Clinical Features

Histopathology

Diagnosis

• Clinical diagnosis in most straightforward cases (blanching on pressure is pathognomonic)
• MRI is the imaging modality of choice to determine extent - important before treatment, as extensive spread may not be evident clinically
• Biopsy if diagnosis is in doubt (risk of bleeding; use with caution)
• Distinguish from vascular malformations (low-flow vs. high-flow), pyogenic granuloma, and lymphangioma

Treatment

Conservative / Observation

• The majority will involute spontaneously over time; watchful waiting is appropriate for small, asymptomatic lesions
• Indicated for non-problematic infantile hemangiomas in proliferative or involuting phases

Medical Therapy

Surgical / Invasive Therapy

For adults with cavernous hemangiomas (the common adult type in salivary glands), surgical excision is the primary treatment.

Key Points for Left Oral Mucosa Hemangioma

1. Most are benign with favorable natural history - spontaneous involution is common
2. Lip is the most common site, but buccal mucosa, tongue, and floor of mouth are also frequently involved
3. Get MRI to define extent before any intervention
4. For infantile/pediatric: propranolol is now first-line medical therapy
5. Surgical excision is reserved for lesions that are functionally limiting or fail to involute
6. Recurrence after excision is known - counsel the patient
7. Always differentiate from vascular malformation (malformations do not involute, require different management)

OPG Analysis: Dentigerous Cyst vs. OKC/KCOT

Radiographic Findings on Your OPG

Differential Diagnosis: Key Distinguishing Features

Textbook Reference: OKC/KCOT Radiograph

Radiological Verdict

The features on this OPG are more consistent with OKC/KCOT than a simple dentigerous cyst.

1. Scalloped borders - not typical of a dentigerous cyst
2. Anteroposterior extension into the ramus with minimal cortical expansion (OKC "creeps" along medullary bone)
3. Disproportionately large lesion for a pericoronal cyst in a young patient

Localized Aggressive Periodontitis (LAP)

Current Classification - Important Update

The term "Localized Aggressive Periodontitis" (LAP) was retired by the 2018 AAP/EFP World Workshop Classification. It is now classified as: "Localized Stage III, Grade C Periodontitis - Molar/Incisor Pattern"

Definition (Classic Concept)

Epidemiology

Etiology & Pathogenesis

Key Microorganism

• Small, capnophilic (CO₂-requiring) Gram-negative rod
• Highly virulent strains produce a leukotoxin that destroys neutrophils and monocytes
• JP2 clone of Aa (prevalent in African-descent populations) produces 10-20x more leukotoxin - strongly associated with LAP
• Other organisms: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola

Host Defects

• Impaired neutrophil chemotaxis - neutrophils fail to migrate normally to the periodontal tissues
• Reduced neutrophil phagocytic capacity
• Elevated prostaglandin E2 and IL-1β production - drives bone resorption
• Strong genetic predisposition - familial clustering is common

Classic Clinical Features

Radiographic Features

• Arc-shaped (angular) bone loss around first molars - vertical bone defects on mesial and distal of first molars
• "Mirror image" pattern - bilateral and often symmetric
• Bone loss extending from the cervical third to the middle/apical third of roots
• Incisors show crestal bone loss
• Normal bone levels around other teeth (distinguishes from generalized disease)

Diagnosis (2018 Classification Framework)

Treatment

Step 1 - Risk Factor Control / Patient Education

• Oral hygiene instruction
• Smoking cessation
• Dietary counseling
• Systemic disease control if applicable

Step 2 - Cause-Related / Non-Surgical Therapy

• Scaling and root planing (SRP) - full-mouth within 24-48 hours ("full-mouth disinfection")
• Systemic antibiotics - critical in LAP because Aa invades tissue and SRP alone cannot eradicate it:
  • Amoxicillin 500 mg + Metronidazole 500 mg, TID × 7-14 days - most evidence-based combination
  • Doxycycline 100 mg OD × 14-21 days (alternative, especially if penicillin-allergic)
• Antibiotics should be given adjunctively with SRP, not alone

Step 3 - Surgical Therapy (if needed after reassessment ~8-12 weeks)

• Flap surgery for residual pockets ≥6 mm
• Osseous surgery for intrabony defects
• Regenerative procedures - guided tissue regeneration (GTR), bone grafts for angular defects at first molars (LAP tends to respond well to regeneration due to young age and good healing potential)

Step 4 - Supportive Periodontal Therapy (Maintenance)

• 3-monthly recall for at least 1 year
• Monitor for disease recurrence and tooth loss
• Long-term maintenance is essential - recurrence rate is high

Systemic Associations to Screen For

• Papillon-Lefèvre syndrome (palmar-plantar hyperkeratosis + severe periodontitis; cathepsin C mutation)
• Chediak-Higashi syndrome (neutrophil granule defect)
• Leukocyte adhesion deficiency (LAD)
• Cyclic neutropenia
• Hypophosphatasia (premature loss of deciduous teeth)
• Down syndrome (trisomy 21)

Prognosis

• Good with early, aggressive treatment - young age means excellent regenerative capacity
• Poor without treatment - can progress to generalized disease
• First molars are most frequently lost if untreated
• Antibiotic adjunctive therapy significantly improves outcomes compared to SRP alone

Stated Diagnosis: LAP involving 37 and 47

Radiographic Findings

Tooth 47 (Lower Right Second Molar)

• Severe vertical (angular) bone loss - predominantly on the mesial aspect
• Bone loss extends to the apical third / near root apex (>50% root length loss)
• Radiographic furcation involvement (bifurcation radiolucency) - Class II/III
• Distal aspect also shows vertical loss reaching middle third of root
• Appears to have a deep restoration or carious lesion in the crown
• Prognosis: Poor to Hopeless without intervention; high risk of tooth loss

Tooth 37 (Lower Left Second Molar)

• Vertical (angular) bone loss on the mesial aspect
• Extends to the middle third of root (~33-50% root length)
• Possible early furcation involvement
• Distal bone level relatively preserved
• Prognosis: Guarded to Poor - Stage III, Grade C

Rest of Dentition

Critical Diagnostic Discussion

The bone loss is confined to second molars (37/47), NOT the classic first molar/incisor pattern of LAP.

Alternative Diagnoses to Consider

• Tooth 47 shows a deep restoration/carious lesion suggesting possible pulpal necrosis
• A primary endodontic infection can drain through the furcation or lateral canals, creating a radiolucency mimicking periodontal bone loss
• The furcation involvement on 47 may be endodontic in origin
• Do: Pulp vitality test on 47 - if non-vital, treat endodontically first before periodontal surgery

• The third molars are absent on this OPG
• Mesioangularly impacted wisdom teeth are the most common cause of isolated deep mesial vertical defects on second molars
• If 38/48 were extracted late, they often leave a non-healing deep periodontal pocket and vertical bone defect on the mesial of the adjacent second molar
• Ask the patient: When were wisdom teeth extracted? Were there pericoronal infections?

• Under the 2018 AAP/EFP classification, this can still be classified as "Localized Stage III-IV, Grade C Periodontitis" - the molar-incisor pattern is the classic form, but localized Grade C affecting second molars in isolation is recognized
• Bone loss/age ratio: if bone loss ~50% at age 36 = >1.0 → Grade C confirmed

Treatment Planning

Maxillary Sinusitis: Inhalation Therapy & Full Treatment

What "Inhalation Treatment" Means in Sinusitis

1. Steam inhalation - breathing hot water vapour
2. Intranasal drug delivery - nasal sprays, drops, and irrigations applied directly to the sinus mucosa

Steam Inhalation - Evidence Assessment

Steam inhalation is NOT evidence-based for sinusitis.

Intranasal Drug Delivery - The Effective "Inhalation" Treatments

1. Saline Nasal Irrigation (Most Important Non-Drug Treatment)

2. Intranasal Corticosteroids (INCS) - First-Line Medical Treatment

• Reduce mucosal edema → open sinus ostia → restore drainage
• Recommended by NICE, EPOS 2020, and NIHR for both acute and chronic sinusitis
• High-dose INCS (e.g., mometasone 400 mcg/day) for 14 days in acute sinusitis
• Ongoing use for chronic sinusitis and nasal polyps
• Minimal systemic absorption at standard doses

• Blow nose first
• Tilt head forward slightly
• Direct spray laterally (away from nasal septum) toward the lateral wall / inferior turbinate
• Breathe in gently through the nose

3. Topical Nasal Decongestants (Short-term only)

Full Treatment Algorithm for Maxillary Sinusitis

Acute Bacterial Rhinosinusitis (ABRS)

• Symptoms NOT improving after 10 days, OR
• Symptoms worsen after initial 5-7 days (double sickening), OR
• Severe symptoms from the start (fever >39°C, unilateral facial pain/swelling, purulent discharge)

Chronic Rhinosinusitis (CRS) - >12 weeks

Odontogenic Maxillary Sinusitis (special consideration)

• Rule out periapical abscess, periodontal disease, or failed root canal involving the maxillary posterior teeth as the primary cause
• Dental treatment (extraction, RCT, or periodontal treatment) must precede or accompany sinus treatment
• Often requires FESS if dental origin causes sinus polyps/biofilm

1. Steam inhalation is NOT evidence-based and carries burn risk - do not recommend
2. Saline nasal irrigation (high-volume, hypertonic) is the most effective non-drug inhalation treatment
3. Intranasal corticosteroids are the first-line medical "inhalation" treatment - both acute and chronic
4. Topical decongestants give fast relief but must be limited to ≤3 days
5. Most uncomplicated acute sinusitis resolves without antibiotics
6. Always consider dental cause for unilateral maxillary sinusitis
