A Case of Nasal Dermoid Sinus Cyst / 대한이비인후과학회지

ABSTRACT

Nasal dermoid sinus cyst (NDSC) is a rare congenital malformation which results from anomalous embryological development and occurs in the midline of the nose. An accurate diagnosis using CT or MRI is essential for an appropriate surgical treatment, which in some cases entails cooperation between the neurosurgeon and the oromaxillofacial surgeon. Surgical extirpation is the treatment of choice, and various surgical approaches like vertical-dorsal rhinotomy, lateral rhinotomy, transverse rhinotomy, external rhinotomy, and bicoronal flap approach have been advocated. Rut in the case of intracranial extension, the craniofacial approach is required. We report a 5-year-old girl with NDSC who was successfully managed using the external rhinoplasty approach.
