Vocal Fold Lesions: Nodules, Polyps, Cysts and Phonomicrosurgery

Vocal folds are the main vibratory structures of the larynx — 5-layered: epithelium, superficial lamina propria (Reinke's space), intermediate and deep lamina propria (vocal ligament), vocalis muscle. Voice production depends on the mucosal wave — periodic opening and closing of the epithelium and superficial lamina propria. Disruption of this wave directly affects voice quality.

Vocal nodules: bilateral, symmetric, at the junction of anterior and middle thirds (point of maximum vibration). Chronic mechanical trauma — shouting, poor technique, prolonged speaking. Teachers, coaches, call-centre workers, child singers are typical. More common in women and children.

Vocal polyps: unilateral, often pedunculated or broad-based. Acute trauma — microhaemorrhage after shouting, chronic irritation. Smoking, reflux, allergies contribute. More common in men.

Vocal cysts: epidermoid (keratin-filled, congenital remnant) or mucus retention (obstructed gland duct). Subepithelial, in the depth of the vocal fold. Usually unilateral; reactive lesion on the contralateral side may be seen.

Reinke's oedema (polypoid corditis): smoking + voice misuse causes diffuse oedematous swelling in Reinke's space. Bilateral; in advanced cases can compromise the airway. Classic middle-aged female smoker.

Other lesions: granuloma (posterior commissure, vocal process — from reflux and intubation), papilloma (HPV — recurrent respiratory papillomatosis), leukoplakia (premalignant, smoking), carcinoma in situ and invasive carcinoma. We expand on the clinical framework in our laryngology and voice surgery unit.

History: onset of hoarseness (acute vs chronic), professional voice use, smoking/alcohol, reflux symptoms, allergy, recent URI, intubation history. Hoarseness >2 weeks warrants endoscopic evaluation.

Flexible laryngoscopy: office-based, with topical anaesthesia. Assesses lesion location, size, mobility, and vocal fold motion. First-line imaging.

Stroboscopy: gold standard of laryngology. Stroboscopy visualises vocal fold vibration in apparent slow motion — mucosal wave presence, symmetry, periodicity, phase relation, glottic closure pattern are assessed. Whether the lesion is superficial vs deep, and whether the mucosal wave is preserved/reduced/absent, is critical for surgical planning.

Acoustic voice analysis: fundamental frequency, jitter, shimmer, harmonic-to-noise ratio (HNR), maximum phonation time (MPT). Voice Handicap Index (VHI-10) quantifies subjective impact.

Additional evaluation: phoniatric and SLP assessment in professional voice users; 24h pH-impedance or empiric PPI if reflux suspected; CT/MRI in advanced cases or preoperatively (RLN course if paralysis suspected); biopsy when lesion is suspicious for malignancy.

Multidisciplinary voice clinic: laryngologist + phoniatrist + SLP + sometimes pulmonologist and gastroenterologist — optimal especially for professional voice users and complex cases.

Voice therapy (SLP-led): first-line for vocal nodules and phonotraumatic lesions. 6-12 weeks, 1-2 sessions weekly. Content: breath support, resonance therapy, vocal hygiene education, vocal function exercises (Stemple), Lessac-Madsen resonance therapy.

Vocal hygiene: 1.5-2 L water daily, limit caffeine and alcohol, smoking cessation, steam inhalation, reduce throat clearing (swallow instead), avoid shouting, manage environment (noise, dryness).

Reflux control: laryngopharyngeal reflux has substantial voice effect. PPI 8-12 weeks + lifestyle (no late meals, weight management, head elevation, avoid triggers). Direct acid damage even subclinical worsens lesions.

Smoking cessation: mandatory for Reinke's oedema and premalignant lesions. Passive smoke also relevant.

For professional voice users: voice rest plan (graded to performance load), warm-up/cool-down routine, microphone use, voice coach for technique. Teachers — microphone and classroom acoustic measures.

Conservative success: 70-85% in vocal nodules (especially children and young adults); 60-70% resolution of reactive nodule contralateral to a cyst. Polyps usually do not resolve but may shrink; surgical plan becomes flexible. Cysts do not respond to conservative measures.

Steroids: oral or intralesional in limited indications — acute inflammation (post-haemorrhage), emergency professional performance, granuloma (alongside reflux therapy). Long-term use not recommended. More detail: vocal cord page.

Indications: lesions unresponsive to conservative measures (cysts; large or long-standing polyps), professional voice user requiring quick recovery, malignancy suspicion, airway threat (large Reinke's oedema). Recurrence after voice therapy.

Surgical principle: preserve the mucosal wave. Superficial lamina propria (Reinke) and vocal ligament are essential for vibration — sparing these is the cardinal goal. "Less is more" philosophy.

Microflap technique: suspension laryngoscopy (Lindholm or Steiner), operating microscope at 200-400x. Microincision: micro-sickle blade along the lateral edge of the lesion through the epithelium; lesion dissected from superficial lamina propria with microforceps and microscissors. Lesion excised; microflap laid back — no sutures.

Cyst surgery: epithelial incision over the cyst dome, dissection of the cyst from surrounding tissue without rupture, en-bloc removal (rupture causes recurrence). Posterior microflap especially for epidermoid cysts.

Polyp surgery: pedunculated polyp excised at the stalk; broad-based with microflap. Never cut the vocal ligament.

Reinke's oedema: epithelium lifted by microflap, polypoid mucus aspirated/removed, epithelium partially trimmed if needed. Bilateral same-session can rarely cause early postop airway issue — usually staged (4-6 weeks apart) or airway monitoring.

Laser use: KTP (532 nm) — papilloma, vascular lesions, superficial cautery in Reinke's. CO2 — more controlled cutting. Angiolytic lasers (KTP, dye) — advanced approach especially for professional voice users targeting subepithelial vessels with minimal damage.

Postoperative: voice rest 5-10 days (strict, even whispering limited). Next 2-4 weeks limited voice + start voice therapy. Full activity by 6-8 weeks.

Voice rest: absolute silence 5-7 days; no whispering (whispering closes vocal folds and is traumatic). Use writing, texting, gestures. Plan communication ahead (no phone, meetings).

During rest: suppress swallowing-effort, coughing, sneezing — to avoid vocal fold collision. Continue reflux therapy; head elevation; absolute no smoking.

Voice therapy: from postop week 2-3 with SLP. Re-learn correct technique — poor technique caused the nodule/polyp. 4-6 weeks of weekly sessions, then as needed.

Stroboscopy at 2-3 months — confirm return of mucosal wave and glottic closure. VHI-10 for subjective outcome.

Return for professional voice users: stage/lecture/call-centre at 6-8 weeks with laryngologist clearance. Opera singers, actors may need 8-12 weeks — voice stamina takes longer.

Outcomes: anatomic (lesion removal) >95%; sustained improvement 80-90% (the key factor is lifestyle and technique change). Complications rare: adhesion (anterior commissure — prevented with steroid coverage 6-8 weeks), subglottic stenosis (after papilloma surgery), vocal scar (mucosal wave loss — permanent dysphonia).

Recurrence: in cases where technique is not preserved, voice misuse continues, reflux/smoking persists. Vocal nodules 20-30% recurrence (especially if technique not corrected); polyps 5-10%; cysts 3-5%; Reinke's oedema (if smoking continues) >50%. Related reading: our second opinion service.
