According to Bryce and Cranston, prolapse of the laryngeal ventricle is a protrusion of the ventricular mucosa into the laryngeal cavity from inflammatory hyperplasia or edema. This 53 year old female patient was admitted to our hospital March 11, 1977 with the chief complaints of dyspnea and hoarseness. On admission, evaluation of the larynx revealed smooth surfaced round pink-reddish mass protruding bilaterally beneath the false cord. The airway was almost completely obstructed by the tumor mass, but neither ulceration nor infiltration was seen, also no lymphnode was palpable in the neck. Tracheotomy was performed for the relief of dyspnea and biopsy was done endoscopically. Histologic study showed chronic inflammation. On April 2, 1977 laryngofissure was performed under general anesthesia. Laryngeal examination revealed smooth surfaced, plate like, pinkreddish mass protruding bilaterally from both laryngeal ventricles into the laryngeal cavity and extending the whole length of the ventricle antero-posteriorly and touching each other. Biopsy was taken of the mass and the result was non-specific inflammatory hyperplasia of the larynx. Postoperatively, the air way is completely clear of obstruction but mild hoarseness still remains. No recurrent mass is visible in the larynx. In view of the symptoms, operative findings and histological findings, this case is diagnosed as "Prolapse of the laryngeal ventricle". The prolapse of the laryngeal ventricle is a very rare lesion and is reported with review of the literature.
