ABSTRACT

Nasal dermoid sinus cysts are uncommon congenital midline anomalies. They consist of 1-3% of all dermoid cysts, and 11-12% of head and neck located dermoid cysts. There may be intracranial extension, which may not be de-tected during physical examination. Most of the lesions are diagnosed in the first three years of childhood, but in some cases diagnosis can be delayed until a later age. Recurrent infections, airway obstruction, and intracranial complications may occur if the diagnosis is prolonged. In this study, we present two cases in whom nasal dermoid sinus cysts were unexpectedly diagnosed during open rhinoplasty. (Gazi Med J 2012; 23: 154-6)
