Application of 3-dimensional Modeling to Plan Totally Endoscopic Per-Meatal Drainage of Petrous Apex Cholesterol Granuloma.
نویسندگان
چکیده
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 and printing technology. Exemption was granted by the hospital’s Research Ethics Board.

Endoscopic transrostral- transsphenoidal approach to petrous apex cholesterol granuloma: case report.
Cholesterol granuloma (CG) of the petrous apex is an inflammatory reaction to the by-products of eroded marrow cavities secondary to chronic obstruction of air cells within the petrous pyramid. We report a case of cholesterol granuloma in the left petrous bone occurring in a 28-year-old woman with an unusual presentation. The woman presented with a 6-month history of intermittent left hemicrani...
متن کاملA novel endoscopic technique for long-term patency of cholesterol granulomas of the petrous apex.
INTRODUCTION Cholesterol granulomas (CGs) are rare benign cystic lesions containing cholesterol crystals in a gluelike fluid and are frequently found in the petrous apex (PA) and in the nearby anatomical area. The gold standard treatment of PA CG counts on its surgical drainage and ventilation to prevent recurrence. Different surgical approaches have been described in the past to achieve draina...

Background Cholesterol granulomas arising at the petrous apex can be treated via traditional open surgical, endoscopic, and endoscopic-assisted approaches. Endoscopic approaches require access to the sphenoid sinus, which is technically challenging in patients with conchal sphenoidal anatomy. Clinical Presentation A 55-year-old woman presented with intermittent headaches and tinnitus. Formal au...
متن کاملCASE REPORT Lobulated Petrous Apex Cholesterol Granuloma Treated with Infracochlear and Transsphenoidal Approaches
404 Petrous apex cholesterol granulomas are relatively rare lesions. They are usually unilocular and treated with simple fenestration. However, lobulated lesions require total removal of debris inside the cysts. Herein, we report a first case with a lobulated petrous apex cholesterol granuloma. The lesion extended from cerebello-pontine angel to the clivus. It was lobulated and contained debris...
