Complications
Risk is low in uncomplicated acute infectious laryngitis but high in diphtheria.
Close follow-up with serial laryngoscopies is of utmost importance.
A multidisciplinary approach should be employed (including ear, nose, and throat; infectious diseases; and anaesthesia).
Acute infectious laryngitis is generally viral and self-limiting, and complications are rare.
In case of heavy voice use, injury to the vocal folds is possible. It can be prevented by voice rest and hydration.
In case of persistent hoarseness that does not improve or resolve within 4 weeks, the patient should be referred to an otolaryngologist. If a serious underlying cause is suspected, the patient should be referred irrespective of duration.[22]
Untreated TB can lead to scarring and laryngeal stenosis.
Extensive voice use may lead to compensatory behaviour and, as a result, muscle tension dysphonia.
Patient education is important, and, in cases of persistent dysphonia, the patient should be referred to a laryngologist.
