title: Nasal dermoid sinus cysts in children.
abstract: Thirty-six children with nasal dermoid sinus cysts were treated in the Department Pediatric Otolaryngology, Armand Trousseau's Children's Hospital (Paris, France) between 1974 and 1994. Ten of the patients presented with a midline cyst only, eight had nasal pits only, and 18 had combined cases. In six of the 36 patients, presurgical imagery indicated signs of intracranial extension of the tract, reaching the foramen caecum without intracranial mass. Three surgical techniques were used: an external rhinoplasty approach with medial crura section in 23 cases, a direct median approach in seven cases, and a paracanthal approach in six cases. Only two cases had meningeal adherences. Two superficial recurrences occurred within the 7-year follow-up period. Widening of the scar occurred in four children after verticomedian approach or nasal pit excision. The external rhinoplasty procedure with medial crura section results in a wide surgical approach, low recurrence rate, and good aesthetic results.
