Mixed laryngocele: a case report and review of the literature.

Laryngocele is a rare, benign dilatation of the laryngeal saccule that may extend internally into the airway or externally through the thyrohyoid membrane. Many laryngoceles are asymptomatic; sometimes they may cause a cough, hoarseness, stridor, sore throat and may present as a swelling on one or both sides of the neck. Laryngocele may be associated with supraglottic squamous cell carcinoma. Computed tomography scan is the most effective imaging method for diagnosis. Surgery is the treatment of choice. A case of large mixed laryngocele in a 75-year-old male is described together with surgical management and followup. A review of the literature is also presented.
