Endoscopic-assisted removal of a nasofrontal dermoid cyst with intracranial extradural extension.

Abstract

Background: Nasal dermoid cysts are rare congenital anomalies that can present with intracranial extension in approximately 10% of cases. Traditional surgical approaches require frontal craniotomy, which is invasive and may lead to significant morbidity.

Objective: We describe a novel, minimally invasive, endoscopic-assisted surgical approach for the removal of a nasofrontal dermoid cyst with intracranial extradural extension.

Methods: A 2-year-old girl with a nasal dermoid cyst extending intracranially was treated using an endoscopicassisted technique through a small skin incision. Surgical steps, intraoperative findings, and postoperative outcomes were recorded.

Results: The procedure allowed complete resection with excellent visualization, reduced morbidity, and satisfactory cosmetic outcomes. No cerebrospinal fluid leakage or recurrence was noted at 6-month follow-up.

Conclusion: Endoscopic-assisted removal is a safe and effective alternative to traditional approaches, providing excellent tumor visualization and better cosmetic results while minimizing surgical morbidity.
