目的:回顾性研究侧颅底肿瘤手术进路、手术技巧和并发症的预防及处理。方法:分析经乳突手术入路及颞下窝入路侧颅底肿瘤切除术的20例侧颅底良、恶性肿瘤病例资料,患者均进行显微手术切除,术中均整块切除肿瘤,并保留重要的血管、神经,并行重建颅底。结果:经术后随访3年或5年以上,无复发者16例(80%),带瘤生存者4例(20%),无因肿瘤复发而死亡的患者。无颅内出血、颅内外感染、术后脑梗死脑脊液漏或皮瓣坏死等并发症。结论:经乳突手术入路及颞下窝入路适合用于侵及颞骨、颅中窝、颞下窝的侧颅底肿瘤切除术。
Objective: To retrospectively study the surgical approach, surgical technique and complications prevention and treatment of side skull base tumors. Methods: Twenty cases of benign and malignant tumors of the skull base underwent mastoid and infratemporal fossa skull base tumor resection were studied. The patients underwent microsurgical resection and all the tumors were resected during operation Maintain important blood vessels, nerves, parallel reconstruction of skull base. Results: Sixteen patients (80%) had no recurrence and 4 patients (20%) survived without any recurrence after 3 years or more follow-up. No patients died of tumor recurrence. No intracranial hemorrhage, intracranial infection, cerebrospinal fluid leakage or necrosis and other complications of postoperative cerebral infarction. Conclusion: The mastoid approach and the infratemporal fossa approach are suitable for the resection of the lateral skull base tumor invade the temporal bone, middle cranial fossa and infratemporal fossa.
