Abstract
The exact incidence of laryngocele is unknown. It has been stated that it probably is always a congenital condition, but it may manifest itself at any age.
Symptoms include peculiar timbre, alteration of tone, and hoarseness or weakness of the voice; various degrees of aphonia; difficult respiration; coughing bouts; and a lateral mass in the neck.
A possible relation between laryngocele and carcinoma of the larynx has been postulated by some observers.
Treatment of laryngocele is surgical, although internal laryngoceles in adults require no treatment. The prognosis is good in both children and adults if no complications develop.
