[Bilateral internal laryngocele with open nasality--report of a case].

Laryngocele is an abnormal saccule dilatation of the ventricle in direct communication with the laryngeal lumen. It is usually filled by air and mostly asymptomatic. This case is reported due to its rarity. A bilateral internal laryngocele with open nasality in 66-year-old man is described. Patient has been observed for 8 years with stable course of the disease and good general condition. Because the squamous cell carcinoma is known to occur in association with laryngocele necessity of control evaluation is very important. The etiology, classification, evaluation is discussed.
