Objective: In order to improve the diagnosis and surgical treatment of cranial hedge cholesteatoma. Methods: The clinical manifestations, diagnosis, microsurgery approach and curative effect of 162 cases of posterior fossa cholesteatoma were analyzed. Results: 149 cases (92.0%) of the tumors were completely resected, and the remaining 13 cases (8.0%) were subtotally resected due to the tight adhesion between the tumor capsule and the brainstem. Four patients (2.5%) died of brain stem ischemia, edema or pulmonary infection within 2 weeks after surgery. Of the 134 patients who received long-term follow-up (mean, 4.5 a), 129 (96.3%) recovered well; 2 (1.5%) had a relapse requiring resection. Conclusion: The early diagnosis of cranial heel cholesteatoma and the use of microsurgical treatment is the main method to improve the curative effect.
