Endoscope-assisted open rhinoplasty approach for removal of nasal dermoid with intracranial extension

Abstract

Nasal dermoid sinus cysts (NDSC) are caused by failure of involution of ectodermal and mesectodermal midline remnants. A 13-month-old girl was found to have a NDSC with a tract traversing the nasofrontal suture line and an intracranial component on MRI. Here we present the first case in a pediatric patient of a resection of a NDSC with intracranial extension through an endoscope-assisted open rhinoplasty approach and frontonasal mini-craniotomy without the need for additional skin incisions or traversing the nasal cavity. This approach provided an excellent intraoperative exposure and cosmetic outcome at 1 year.
