Nasal Dermoid Sinus Cyst Excision with Bicoronal Approach

ABSTRACT

Nasal dermoid sinus cyst is a rare congenital lesion. It may present extracranially as a swelling or a mass on the nose, a skin pit or a sinus. Intracranial complications can be fatal including meningitis, abscess, osteomyelitis, seizures. The treatment of choice is complete surgical excision of the cyst. There are some approaches to this goal such as vertical midline incision, external rhinoplasty approach, bicoronal approach, and endoscopic approach. In this case, we could completely excise the nasal dermoid sinus cyst on the glabella without intracranial extension only with bicoronal incision.
