Background <p>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.</p> Objective <p>We describe a novel, minimally invasive, endoscopic-assisted surgical approach for the removal of a nasofrontal dermoid cyst with intracranial extradural extension.</p> Methods <p>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.</p> Results <p>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.</p> Conclusion <p>Endoscopic-assisted removal is a safe and effective alternative to traditional approaches, providing excellent tumor visualization and better cosmetic results while minimizing surgical morbidity.</p>
