Cholesteatoma of Maxillary Sinus

Abstract

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.

Sphenoid Sinus Cholesteatoma—Complications and Skull Base Osteomyelitis: Case Report and Review of Literature

“…On magnetic resonance imaging (MRI), it appears as low intensity in T1 and high intensity in T2. 9 Diagnosis is confirmed by histology.…”

“…If not possible, marsupialization would be preferred to promote drainage and ventilation to prevent further erosion of surrounding structures and disease progression. 9 Advances in instrument and technique and in endoscopic sinus surgery should allow more success in outcomes.…”

“…8 Ten more cases of maxillary sinus cholesteatoma were reported in the English language after 1980s. 9 Cholesteatomas originated from sphenoid sinus, excluding those extending from the temporal bone to the sphenoid bone are extremely rare. To date, there are 4 cases reported.…”
