PART I: VOICE AND SPEECH REHABILITATION

Physiology of Alaryngeal Voice

Prerequisites for Good Alaryngeal Voice

---

THREE MAIN METHODS OF VOICE REHABILITATION

METHOD 1: TRACHEO-ESOPHAGEAL PUNCTURE / SURGICAL VOICE RESTORATION (TEP/SVR) - GOLD STANDARD

• 1980: Blom and Singer described TEP with a voice prosthesis
• Original concept: An anecdotal observation when a laryngectomee deliberately punctured the posterior tracheal wall (with a heated ice pick), discovered that stoma occlusion + exhalation produced a voice
• Singer and Blom (1980) formalized the technique

• Avoids a second procedure
• Allows earlier voice rehabilitation
• Does not increase fistula risk when done in elective (non-salvage) cases
• Scott-Brown's: "No good evidence that this increases the risk of pharyngocutaneous fistula formation."

---

FLOWCHART 2: TEP Voice Production Mechanism

EXPIRATION (patient closes stoma with finger or HME valve)
        ↓
Air passes from TRACHEA → through ONE-WAY PROSTHETIC VALVE → ESOPHAGUS
        ↓
Air causes vibration of PE SEGMENT (neoglottis / vibratory segment)
        ↓
SOUND produced → amplified by PHARYNGEAL RESONATING CAVITIES
        ↓
Modified by ARTICULATORS (tongue, lips, teeth, palate) → SPEECH

---

Voice Prostheses - Types and Classification

• Blom-Singer (InHealth Technologies) - classic, low pressure, advantage, dual valve
• Provox series (Atos Medical) - Provox, Provox 2, Provox Vega, Provox NID, Provox ActiValve
• VoiceMaster, HiPro, Henley-Cohn, Staffieri (older/less used)

• Tracheal flange
• Esophageal flange
• One-way valve (duckbill or slit design)
• Retention strap/collar

---

Candidacy Criteria for TEP

• Adequate stoma size (≥1.5 cm diameter)
• Good manual dexterity (for self-care)
• Adequate pulmonary reserve
• Motivated patient
• Adequate visual acuity
• Good caregiver support (if patient dependent)

• Very small stoma
• Severe COPD (cannot build adequate pressure)
• Dementia/severe cognitive impairment
• Inability to manage prosthesis
• Severe radiation fibrosis
• Very poor general condition

---

Hands-Free Speech

• The valve seals during expiration (when pressure builds)
• Opens during inspiration
• Patient achieves spontaneous hands-free voice

---

PE Segment Tonicity - Problems and Management

          whispery, wet)          effortful, absent)
               ↓                        ↓
     Digital pressure          Myotomy (at surgery) OR
     against neck              ↓
     Low pressure prosthesis   POST-OP: Botulinum toxin

                               OR Secondary myotomy
                               (rarely done now)

• Injected unilaterally at 3 sites along the posterior cricopharyngeal myotomy line
• Dosage: guided by degree of hypertonicity, neck fibrosis, prior myotomy
• Can be repeated
• Preceded by lignocaine injection to confirm diagnosis

---

Complications of TEP and Voice Prosthesis

• Daily brushing and flushing of prosthesis in situ
• Optional liquid antifungal (nystatin) via flush
• Exdwelling: removed, washed, sterilized overnight in 3% hydrogen peroxide
• Antifungal-impregnated prostheses available
• Newer fungal-resistant materials under development

---

METHOD 2: ESOPHAGEAL SPEECH (ES)

• No prosthesis, no surgery
• No equipment dependency
• Most natural-sounding of non-surgical methods
• "Hands-free" - no stoma occlusion needed

• Hardest to learn (only ~30% achieve functional speech)
• Short utterances (limited air reservoir)
• Low volume, poor loudness
• Long training period (months)

• Old literature: ~25-30% achieve functional ES
• Success dependent on PE segment characteristics

---

METHOD 3: ELECTROLARYNX (EL)

1. Transcervical (neck-type) - most common; device held against neck/submandibular region; vibrations transmitted through skin
2. Intraoral - tube placed in mouth corner; for patients with neck radiation/fibrosis

• Servox (most widely used)
• Western Electric #5
• TruTone
• NuVois

• Easy to learn (available immediately post-op)
• Reliable
• Good for immediate communication post-laryngectomy

• Mechanical, robotic sound quality
• Both hands required (or neck placement)
• Cannot be used while eating
• Needs battery/maintenance
• Poor acceptance long-term

---

METHOD 4: AAC (AUGMENTATIVE AND ALTERNATIVE COMMUNICATION)

• Writing pads/whiteboards
• Mobile phone/tablet text-to-speech apps
• Sign language
• Lip-reading facilitated communication

---

PART II: SWALLOWING REHABILITATION

Physiological Changes After Laryngectomy

Swallowing Problems Post-Laryngectomy

1. Pharyngo-esophageal stenosis/stricture - most common (5-30%)

• At surgical closure site or throughout neopharynx
• Investigation: Esophagography (barium swallow), endoscopy
• Management: Serial dilatation, surgical revision

1. Pharyngocutaneous fistula - early complication (10-15%)

• Risk factors: Prior radiotherapy, malnutrition, diabetes
• Detected by esophagogram (extravasation)
• Management: Conservative initially (NPO, NG tube feeding), surgical closure if persistent

1. Pseudoepiglottis - normal post-op appearance

• Ridge of tissue at anterior surgical bed on fluoroscopy
• Looks like epiglottis (benign)

1. Dysphagia due to radiation fibrosis - progressive

• Long-term: stricture, hypopharyngeal scarring
• Management: Dilatation, swallowing therapy, PEG/PEJ tube

Post-Laryngectomy Swallowing Rehabilitation

• Nasogastric tube feeding
• Nothing by mouth
• Cummings: Feeding typically commenced within 5-7 days post-op (in narrow-field laryngectomy with linear stapler closure)

• Videofluoroscopic swallowing study (VFSS) before oral feeding
• Start with thin liquids or thickened fluids (depending on VFSS findings)
• Speech-language therapist guidance

• Bolus modification (texture, consistency)
• Compensatory swallowing maneuvers
• Postural adjustments
• Thermal-tactile stimulation
• Exercises to strengthen tongue base, pharyngeal constrictors

---

PART III: PULMONARY AND RESPIRATORY REHABILITATION - HEAT AND MOISTURE EXCHANGER (HME)

Physiological Basis

• Warms inspired air to 32°C
• Humidifies air to 95% relative humidity
• Filters particulate matter
• Reduces airways resistance

• Increased mucus production
• Crusting and coughing
• Increased respiratory infections
• Poor sleep quality
• Reduced exercise tolerance

Heat and Moisture Exchanger (HME)

• Small hygroscopic/hygrothermic filter contained in a cassette
• Attached to stoma by: a. Base plate (adhesive on para-stomal skin) b. Inserted into laryngectomy tube

• Standard daily activity HME
• Night HME (lower resistance)
• Exercise HME (higher capacity)
• HME with voice valve attached (enables hands-free speech + pulmonary rehab simultaneously)

• A 2023 study (Ward et al., Head Neck 2023, PMID 36808179) showed significant improvement in pulmonary and related symptoms following adoption of an optimal day-and-night HME regimen
• A 2022 RCT (Longobardi et al., Otolaryngol Head Neck Surg 2022, PMID 35316144) confirmed new generation HME devices optimize pulmonary outcomes post-laryngectomy

---

PART IV: STOMA CARE AND MANAGEMENT

Immediate Stoma Care

• Tracheostomy tube (Shiley/Portex) placed initially
• Regular suctioning (initially)
• Humidified environment in ICU/ward
• Patient education: stoma hygiene

Long-term Stoma Care

• Laryngectomy button or tube insertion
• Regular dilatation if stenosis develops
• Surgical stoma revision (if too narrow for valve/HME)

• Clean with soft gauze/cloth
• Remove crusts gently
• HME cassette changed daily

• All laryngectomees should carry an ID card/medic-alert bracelet
• Emergency resuscitation: bag-mask to stoma (NOT mouth)
• Standard mouth-to-mouth CPR ineffective/dangerous

FLOWCHART 5: Stoma Complications and Management

STOMA PROBLEMS
      |
      ├─── STENOSIS ──→ Dilatation → Revision stoma surgery
      |
      ├─── SECRETIONS/CRUSTING ──→ HME / Humidification / Saline instillation
      |
      ├─── STOMAL RECURRENCE ──→ PET-CT / Biopsy → Salvage RT/surgery
      |
      └─── PERISTOMAL SKIN PROBLEMS ──→ Change base plate / Skin barrier creams

---

PART V: PSYCHOLOGICAL AND SOCIAL REHABILITATION

Psychological Impact of Laryngectomy

1. Loss of natural voice (major identity/communication impact)
2. Altered body image (permanent neck stoma)
3. Fear of cancer recurrence
4. Social isolation (difficulty in communication)
5. Employment difficulties
6. Anxiety and depression (documented in up to 40% of patients)

Psychological Rehabilitation Strategies

• Comprehensive counseling by surgeon + SLT
• Meeting with a "laryngectomee visitor" (peer support from experienced patient)
• Clear explanation of voice rehabilitation options
• Family/caregiver involvement

• Continued counseling and emotional support
• SLT visits during inpatient stay
• Occupational therapy assessment
• Depression screening (PHQ-9)

• Laryngectomy support groups (e.g., National Association of Laryngectomee Clubs - NALC)
• Online support communities
• Vocational rehabilitation / return to work planning
• Marriage/relationship counseling as needed

---

PART VI: NUTRITIONAL REHABILITATION

Phases

• Nasogastric tube: standard
• PEG (percutaneous endoscopic gastrostomy): if long-term feeding needed (post-radiation patients)
• Nutritional goals: 25-35 kcal/kg/day, 1.2-1.5 g protein/kg/day

• Modified texture diets as per VFSS findings
• Dietitian involvement
• Monitor weight, albumin, prealbumin

• Soft/normal diet usually achieved
• Address specific deficiencies (Vitamin D, zinc)
• Weight monitoring

---

PART VII: OLFACTION AND TASTE REHABILITATION

Nasal Airflow Induction Maneuver (NAIM) - "Polite Yawn"

• Patient performs a gentle "polite yawn" with lips closed (lowering floor of mouth, drawing air nasally)
• This creates low-pressure nasal airflow
• Restores smell and taste to near-normal
• Can be taught by SLT or OT

---

PART VIII: MULTIDISCIPLINARY TEAM IN REHABILITATION

---

PART IX: SECONDARY VOICE RESTORATION

Assessment Steps for Secondary TEP (Scott-Brown's):

1. PE segment tonicity assessment - videofluoroscopy first
2. Botulinum toxin injection if PE segment is hypertonic
3. Stoma assessment - revise if too narrow
4. Lung function - must be adequate
5. TEP creation under endoscopic/surgical guidance
6. Prosthesis sizing - careful measurement with sizing gauge
7. Prosthesis selection - from range of diameters/lengths/opening pressures
