Cholesteatoma of Maxillary Sinus: What Is the Best Surgical Approach?.

Cholesteatoma is a relatively common disease entity within the middle ear or mastoid cavity but cholesteatoma of the paranasal sinuses is a rare diseases entity, especially in the maxillary sinus. As the authors recently experienced a patient of maxillary sinus cholesteatoma, the authors tried to review all the literatures previously reported on the "Cholesteatoma of the maxillary sinus." The aim of this study was to describe authors' recent experience and review previously reported patients of cholesteatoma of the maxillary sinus. Additionally, it is to describe the clinical features focusing on the computed tomography findings and to elucidate which approach may be best for complete excision. The authors thoroughly reviewed 10 patient reports written in English regarding the cholesteatoma of maxillary sinus which have been published since the 1980s. Based on authors' review, the authors suggest some conclusions. First, the diagnosis of cholesteatoma, although rare, should be considered for any slowly expansile lesion of the maxillary sinus. Second, there was no specific computed tomography finding that was helpful for the diagnosis of maxillary sinus cholesteatoma. Last, the surgical approach to cholesteatoma of the maxillary sinus should be chosen to allow visibility and complete removal according to the size, location, and extent of diseases.
