Synopsis

Inflammation of the vocal cords causing hoarseness of voice. Subtypes include acute presentation, typically caused by upper respiratory infection or phonotraumatic behaviors, or chronic presentation lasting over 3 weeks. Chronic causes include prolonged phonotrauma, repeated exposure to inhaled irritants including smoking, chronic sinusitis with postnasal drip, chronic alcohol abuse, laryngopharyngeal reflux, or chronic coughing. Patients typically present with symptoms of hoarseness, voice change, pharyngitis, dry cough, globus sensation, dry throat, and dysphagia. Signs such as edema and hemorrhage may be present in patients with vocal cord trauma.

Treatment includes voice rest, hydration, humidifiers, and for chronic cases, addressing the underlying cause, such as quitting smoking or improved vocal behaviors and hygiene.
