[Frontozygomatic dermoid cysts]

Abstract

Dermoid cysts are embryological derivatives from soft tissues. They result from an ectodermic inclusion in the mesoderm, during the early embryonic development. These cysts have a slow development and are mostly encountered in the pediatric population. Eighty percent of them are located in the head and neck area, and most of them are on the frontozygomatic suture. They are superficial or deep on clinical examination. The diagnosis is mostly easy, sometimes with the help of radiological examination. The confirmation is histological. Surgical removed by an open approach, without cyst rupture is the gold standard treatment.
