目的探讨改良上颌骨拆装术在治疗前中颅底肿瘤中的应用。方法回顾性分析采用改良上颌骨拆装手术入路方式切除前中颅底肿瘤10例。其中良性肿瘤9例,恶性肿瘤1例。观察术后疗效,并对10例患者进行术后12个月到5年的随访。结果根据肿瘤性质、大小及位置的不同而采用改良上颌骨拆装手术入路方式完整切除肿瘤。患者术后生活质量明显提高,9例良性肿瘤术后无复发,术后2例发生脑脊液鼻漏,7d后自愈。1例恶性肿瘤患者术后1年死于脑转移。结论术前对肿瘤情况进行充分的评估,根据具体情况选择距离肿瘤最近、能充分暴露肿瘤的改良上颌骨拆装入路,不仅可以完全切除肿瘤,而且创伤小,患者术后生活质量得到提高。
Objective To explore the application of modified maxillary disassembly in the treatment of anterior skull base tumors. Methods Retrospective analysis of 10 cases of anterior skull base tumors excised by modified maxillary disassembly and surgical approach. Among them, 9 cases were benign and 1 was malignant. The postoperative efficacy was observed. Ten patients were followed up for 12 months to 5 years. Results According to the nature of the tumor, size and location of the modified maxillary disassembly and surgical approach to complete removal of the tumor approach. The postoperative quality of life of patients was significantly improved. No recurrence was found in 9 patients with benign tumors. Cerebrospinal fluid rhinorrhea occurred in 2 patients and recovered after 7 days. One case of malignant tumor died of brain metastasis one year after surgery. CONCLUSIONS: The condition of the tumor is fully evaluated before surgery. According to the specific conditions, the maxillary disassembly approach, which can fully expose the tumor and select the nearest tumor, can not only completely remove the tumor but also reduce the trauma, and improve the postoperative quality of life.
