Assessment of patients with laryngeal symptoms
Patients should be assessed for airway patency. Presence of stridor or respiratory distress should prompt emergency referral to a facility where airway support can be provided quickly if needed.
Following airway assessment, patient history should cover:
- the nature and chronology of voice symptoms
 - exacerbating and relieving factors
 - patient's voice use and requirement
 - presence of associated red flag symptoms
 - life style factors e.g. smoking, diet, hydration
 - effect on quality of life and psychosocial wellbeing
 
Investigations commonly include:
- general head and neck examination - oral cavity, oropharynx, and neck
 - assessment of the patient's voice - can be done through
- a simple scale:  
- grade 1 (subjectively normal voice),
 - grade 2 (mild dysphonia),
 - grade 3 (moderate dysphonia),
 - grade 4 (severe dysphonia),
 - and grade 5 (aphonic) plus use of additional qualifiers used as necessary - for example, breathy, strained
 
 - GRBAS (grade, roughness, breathiness, asthenia, strain) scale
- grades hoarseness, roughness, breathiness, aesthenia (weakness), and strain on a scale of 0-3
- 0 = normal, 1 = mild degree, 2 = moderate degree, and 3 = high degree (1).
