چکیده
Otitis media (OM) is an infection localized in the middle ear: mastoid, middle ear cavity, Eustachian tube. The classification of OM includes otitis media with effusion, otitis media without effusion, and chronic otitis media. A rare complication of chronic otitis is cholesterol granuloma of the petrous apex. It may develop in any aerated portion of the temporal bone but most commonly develops when a pathologic process obstruct the air cell tracts to the petrous apex preventing normal aeration.

First stage in predicative measure for transnasal transsphenoidal approach to petrous apex cholesterol granuloma.
OBJECTIVES/HYPOTHESIS This study evaluates the feasibility of the transsphenoidal approach to petrous apex cholesterol granuloma based on the petrous angle. This is the angle centered at the vomer, extending between the medial aspect of the C3 segment of the internal carotid artery and the occipital protuberance. The aim of this study is to determine the average petrous angle in a population of...

Cholesterol granulomas are benign granulomatous lesions caused by tissue reaction to a foreign body such as cholesterol crystals. These crystals have been are associated with pathological conditions of pneumatized spaces, including those causing inadequate aeration, obstruction of drainage, and hemorrhage in pneumatized spaces, and where materials trapping materials, such as hemosiderin or chol...
متن کاملUsefulness of Image Guidance in the Surgical Treatment of Petrous Apex Cholesterol Granuloma
The petrous apex is a pyramid-shaped structure, located medial to the inner ear and the intrapetrous segment of the internal carotid artery. Lesions of the petrous apex can be surgically treated through different surgical routes. Because of the important neurovascular structures located inside the temporal bone, anatomical 3D knowledge is paramount. For this reason, image-guided surgery could r...

C holesterol granuloma (CG) of the petrous apex (PA) may be asymptomatic or enlarge to cause symptoms from compression of neural and vascular structures within the temporal bone. Surgical decompression may then be indicated. We present a case of PA-CG where the feasibility of decompression with a minimally invasive permeatal infracochlear approach was first assessed through 3dimensional imaging...
