Abstract
Because X-ray evaluation of the larynx is an unreliable method of detecting laryngoceles, a study based on the systematic measurement of the ventricular depth in surgical specimens was carried out to determine the frequency of laryngoceles and their relationship to laryngeal carcinomas. The frequency of laryngoceles was found to be about 2% in the normal larynx. The frequency in laryngeal cancer specimens was about 18%. This difference demonstrated the role of cancer in the genesis of laryngoceles. A close relationship between the ventricular diverticuli and the tumors was observed on microscopic examination in half of the laryngeal carcinomas associated with laryngoceles. These carcinomas can be considered to have developed on the laryngoceles. Depending upon the degree of tumor spread and the number of laryngoceles involved, different types of carcinoma developing in laryngoceles can be recognized. This particular form of tumor can be misinterpreted as an ulcerated vestibular tumor, in which case inappropriate treatment may be tried.
