The managament of rare nasal mass-nasal dermoid sinus cysts: open rhinoplasty.

The differential diagnosis of midline nasal masses includes inflammatory lesions, post-traumatic deformities, benign neoplasms, malignant neoplasms, congenital and vascular masses. Midline congenital lesions of the nose are rare congenital anomalies. Their incidence is estimated at 1 per 20,000 to 40,000 births consisting of gliomas, encephaloceles, and nasal dermoid sinus cysts. Nasal dermoid sinus cysts account for 1-3% of dermoid cysts overall and 11-12% of head and neck dermoids. Most lesions are diagnosed within the first three years of life but in some cases the diagnosis can be prolonged. We present an 18-year old and a two and a half-year old male patients who are concerned about drainage from the tip of the nose with recurrent infection and operated with a diagnosis of nasal dermoid sinus cyst.
