侧颅底疾病的外科治疗及颅底重建（附20例报告）

目的探讨侧颅底疾变的外科治疗和体会。方法回顾性分析20例侧颅底疾病患者的临床资料,其中颞骨占位性病变破坏内听道、颈静脉孔区等占位病变与颅内沟通者1 1例,采取经迷路、乳突腔引流以及经乳突切除肿瘤手术;中耳炎性疾病破坏鼓室、鼓窦天盖与颅内沟通者2例,采取扩大乳突根治手术;外伤与畸形造成侧颅底骨质破坏,脑脊液耳漏、鼻漏7例,采取经迷路、乳突修补手术。结果其中颞骨占位性听神经瘤3例、面神经肿瘤3例、静脉孔区胆固醇肉芽肿1例、原发于颞骨的胆脂瘤4例,肿瘤均完全切除;中耳胆脂瘤2例,乳突根治术后无复发;Mondini畸形合并内听道底骨质缺损导致耳漏2例、颞骨骨折致耳漏5例,术后脑脊液漏消失。重要的神经、血管、位听器官以及颅底和颅脑组织得到保护或重建。结论外科手术是治疗侧颅底疾病的主要方法,术中应注意保护重要的血管、神经、位听器官以及颅底、颅脑组织。
