Management of Persistent Sore Throat and Hoarseness

Introduction to Guideline

The American Academy of Otolaryngology-Head and Neck Surgery recommends laryngoscopy for patients with persistent sore throat and hoarseness that exceeds the expected course of benign viral illness, typically beyond 3 weeks, to rule out serious pathology including laryngeal cancer 1, 2, 3

Patients presenting with severe unilateral throat pain, trismus, uvular deviation, and "hot potato voice" may have peritonsillar abscess requiring surgical drainage, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 4
The American Academy of Otolaryngology-Head and Neck Surgery also suggests that persistent high fever with severe pharyngitis in adolescents/young adults warrants consideration of Lemierre syndrome 4, 3
Difficulty swallowing, drooling, neck tenderness, or swelling may indicate epiglottitis, retropharyngeal abscess, or parapharyngeal abscess requiring airway management, according to the Annals of Internal Medicine 5
Hemoptysis, dysphagia, odynophagia, otalgia, or airway compromise are concerning features mandating immediate laryngoscopy, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 1, 2

Laryngoscopy should be performed when hoarseness fails to resolve by a maximum of 3 months after onset, or irrespective of duration if a serious underlying cause is suspected, according to the American Academy of Otolaryngology-Head and Neck Surgery 1, 2, 6, 7
Viral laryngitis symptoms typically last 1-3 weeks, and symptoms persisting beyond 3 weeks already exceed the expected viral course, warranting evaluation, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 1, 2, 7, 3

A history of tobacco or alcohol use increases the risk of polypoid lesions and head and neck cancer, and requires immediate laryngoscopy, according to the American Academy of Otolaryngology-Head and Neck Surgery 1, 6
Concomitant neck mass, unexplained weight loss, progressive worsening of symptoms, neurologic symptoms, recent neck surgery or intubation, immunocompromised status, and occupational voice use are all red flags requiring immediate laryngoscopy, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 1, 2, 6, 7, 8

Inhaled corticosteroid use for asthma/COPD can cause hoarseness from direct irritation or fungal laryngitis, according to the American Academy of Otolaryngology-Head and Neck Surgery 1, 6, 7
Recent radiation to the neck is associated with hoarseness in 8% of cases, and recent anterior cervical spine surgery, thyroid or carotid surgery, and cardiac surgery can also cause hoarseness, as suggested by the American Academy of Otolaryngology-Head and Neck Surgery 1, 6, 8

Ibuprofen or acetaminophen can be used for symptomatic relief of sore throat, and adequate hydration with cool liquids is also recommended, according to the American Academy of Otolaryngology-Head and Neck Surgery and the Annals of Internal Medicine 4, 9, 5
Empiric antibiotics should not be prescribed without proper evaluation, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery and the Annals of Internal Medicine 5, 4, 3

Laryngeal cancer, vocal fold nodules, polyps, or granulomas, vocal fold paralysis, gastroesophageal reflux disease, fungal laryngitis, and chronic streptococcal carrier state with viral superinfection are all potential differential diagnoses, according to the American Academy of Otolaryngology-Head and Neck Surgery and the Annals of Internal Medicine 10, 4, 3, 8
