Abstract
Objectives/Hypothesis:
We present the case of a 21‐year‐old woman who underwent endoscopy‐assisted surgery with topical mitomycin for a large cholesterol granuloma in the petrous apex that involved the eustachian tube.
Study Design:
Case report.
Methods:
Minimally invasive surgery was performed on the cholesterol granuloma with endoscopic assistance, and topical mitomycin (0.4 mg/mL) was administered to prevent scarring of the newly created drainage/ventilation route. With the endoscopic approach, the drainage/ventilation route was secured not only from the tympanic cavity, but also using a guidewire inserted from the pharyngeal orifice of the eustachian tube.
Results:
The drainage/ventilation route between the nasopharynx and middle ear cavity involving the cholesterol granuloma has been preserved more than for 9 months postoperatively. Her hearing has recovered.
Conclusions:
This less invasive technique is a surgical option for patients with a large cholesterol granuloma in the petrous apex involving the eustachian tube. Laryngoscope, 2009
