Frontal Sinus Cholesteatoma Presenting with Intracranial and Orbital Complications: Diagnosis and Treatment

Frontal sinus keratoma or cholesteatoma is a rare disease of paranasal sinuses and presents as a slow-growing mass that becomes symptomatic as it grows to the surrounding structures. Intracranial complications are not a common presentation and are potentially life-threatening. Frequently the final diagnosis is only made intraoperatively because several other frontal sinus tumors behave likewise. Definitive treatment requires complete removal of the keratoma, and a combined endoscopic and external frontal sinus approach is a good treatment option. In this report, we presented a 68-year-old female with frontal sinus cholesteatoma with diagnostic and therapeutic features of this pathology with the review of the literature.
