Step 1 of 6
Entry, Airway / Emergency Screen & Duration Triage
Define the voice complaint · screen for airway threat · split into acute (<2–3 weeks) vs chronic (>4 weeks) routes.
Hoarseness is a symptom, not a diagnosis. Patients present with a spectrum of voice complaints — change in quality, breathy voice, roughness, vocal fatigue, aphonia, loss of pitch range, reduced endurance, strained or strangled voice, intermittent voice breaks, globus, or singing limitation. The first task is to convert the complaint into one of two anatomic categories (true laryngeal vs functional) and into one of two temporal categories (acute vs chronic) — and to screen for airway threat at every step.
Airway emergency indicators — stridor, respiratory
distress, rapid progression, severe dyspnoea, post-extubation
distress, suspected bilateral vocal-fold immobility, large
obstructing lesion, haemoptysis, severe aspiration — route to
the emergency airway pathway (flexible laryngoscopy
immediately, oxygen ± Heliox, nebulised adrenaline if
indicated, ICU / anaesthesia activation, controlled airway
planning with awake fibreoptic intubation, operative airway
assessment, or tracheostomy as needed). See the parallel
framework_red_flag and Acute Airway Obstruction chapter for
the full algorithm.
Duration triage (see framework_duration_triage and the
bespoke duration_triage_matrix). Acute dysphonia (<2–3 weeks)
in an otherwise well patient is usually viral laryngitis, URI,
acute phonotrauma, allergic / irritant exposure, or acute
reflux — managed with voice conservation, hydration, vocal
hygiene, and reflux precautions. Chronic dysphonia (>4
weeks) mandates complete laryngeal examination — no
empirical management.
- Define the voice complaint — quality · breathiness · roughness · pitch · endurance · breaks
- Screen for airway emergency (stridor · distress · bilateral immobility · large lesion · haemoptysis)
- Acute (<2–3 weeks) → conservative trial + reassess
- Chronic (>4 weeks) → mandatory laryngeal visualization
- Hoarseness >2–4 weeks is never treated empirically
- Singers / professional voice users → earlier stroboscopy threshold
Key statistics
Empiric-management risk
>2–4 weeks = always image
Multiple national guidelines (AAO-HNSF, ENT-UK) converge on the rule that hoarseness persisting more than 2–4 weeks mandates laryngoscopy before any further treatment.
★ High-yield pearls (chapter-wide)
- Hoarseness persisting more than 2–4 weeks ALWAYS requires laryngeal visualization — no chronic dysphonia is treated empirically.
- The first decision in every hoarseness presentation is whether the airway is threatened — stridor / distress / bilateral fold immobility short-circuits the algorithm.
- Videostroboscopy is essential for professional voice users, scar / sulcus, paresis, vascular lesions, and any subtle pathology — flexible laryngoscopy alone misses these.
- Voice therapy is foundational — for most benign mid-membranous lesions, behavioural treatment alone resolves or prevents the need for surgery.
- Unilateral leukoplakia in a smoker is dysplasia or carcinoma until proven otherwise — direct laryngoscopy + biopsy is mandatory.
- Unilateral vocal-fold immobility demands imaging the entire vagus / RLN course — skull base to mediastinum (CT or MRI).
- Vocal-fold haemorrhage is a phonotrauma emergency in the professional voice user — absolute voice rest, serial stroboscopy, no premature phonation.
- Reflux is over-diagnosed and over-treated — empirical PPI in non-LPR dysphonia delays the real diagnosis and exposes the patient to long-course PPI risks.
- Spasmodic dysphonia is speech-triggered laryngeal dystonia, not a functional disorder — botulinum-toxin injection is first-line, not voice therapy.
- Phonomicrosurgery without prior stroboscopy is operating blind — the vibratory layer of Reinke's space is not visible on flexible laryngoscopy.

Decision tree
The airway / emergency screen is the first gate. Duration triage (acute <2–3 weeks vs chronic >4 weeks) is the second. For the chronic patient, laryngoscopy and stroboscopy findings route to one of sixteen pathways (A–P). The persistent-hoarseness-must-be-imaged rule and the silent-aspiration-of-voice (subtle paresis missed without stroboscopy) cross-cut every column.
