Abstract: Frontotemporal dermoid cysts with a cutaneous sinus tract in the sphenoid bone are rarely found, and furthermore, the spreading of these cysts across the frontal branch of the facial nerve has not been reported. Herein, we present a 5-year-old case of a dermoid cyst successfully resected with preservation of this nerve using a combined extracranial and intracranial approach. This approach is recommended for a safe and radical resection of the lesion and for securing an aesthetic outcome.
