Anterior Fontanelle Dermoid Cyst: Surgical Technique

Abstract

Dermoid cysts are benign congenital lesions that usually appear on the surface of the skull, mainly on the anterior fontanelle. Diagnosis is usually made in the first months of life by physical examination and imaging studies such as CT, MRI, or ultra sound (US) Doppler. It is important to distinguish it from other similar lesions that represent greater surgical complexity, morbidity, and mortality. In this work, we show the principle differential diagnoses, the diagnostic approach, and the surgical technique used in the resection of the dermoid cyst located over the anterior fontanelle.
