Nasal Dermoid Cyst Excision with a Lateral Rhinotomy Approach through the Nasal Alar Sulcus

Congenital midline nasal masses are uncommon, occurring anywhere from 1 in 20,000 to 1 in 40,000 births.[1] They result from anomalies in neural tube closure between the 3rd and 4th week of gestation.[2] Pediatric nasal midline masses of ectodermal origin include nasal dermoids (ND) and nasal dermoid sinus cysts (NDSC). NDSCs are characterized by intracranial extension whereas NDs are limited to the nasal dorsum, medial canthus, or glabella.[3] NDs are the most common congenital midline nasal mass and develop as a result of failed involution of the neuroectomderm in the prenasal space.
