真正的中耳乳突瘤发生在迷路和面神经内侧并延伸到岩尖是不常见的病变。 最近的技术，总矩阵删除和闭塞要求耳神经外科医生是知识的颞内面神经动员技术。 全切除和闭塞的中耳瘤基质可能会减少经常护理外置腔的需要。 然而，这些程序可以与广泛复发的残留疾病和密切的放射学随访是必要的。 我们回顾了十例岩尖角化瘤的治疗经验。 6例患者采用外置技术治疗，4例患者接受了岩部次全切除术和闭塞术。 这两种方法的优点，缺点和并发症，并建议选择一个特定的方法的指导方针。
True cholesteatomas developing medial to the labyrinth and facial nerve with extension into the petrous apex are uncommon lesions. More recent techniques of total matrix removal and obliteration require the otoneurosurgeon to be knowledgeable of intratemporal facial nerve mobilization techniques. Total cholesteatoma matrix removal and obliteration may obviate the need for frequent care of the exteriorized cavity. However, these procedures can be associated with extensive recurrence from residual disease and close radiographic follow-up is a necessity. We review our experience with ten cases of petrous apex keratoma treated with both techniques. Six cases were managed with an exteriorization technique and four patients underwent subtotal petrosectomy with obliteration. Advantages, disadvantages, and complications of both methods are presented and guidelines for selecting a particular approach are suggested.
