内镜下颅底手术体会

Clinical experience with nasendoscopic surgery in nose-skull base area

目的总结内镜下颅底手术的方法和临床经验。方法回顾性分析2003年7月～2011年8月在鼻内镜下完成的鼻颅底区域手术15例临床资料,探讨鼻颅底手术的相关技术与方法,总结临床经验。结果 15例均采用鼻内镜下进行鼻颅底手术,所有患者均取得满意疗效。其中垂体瘤7例,术后视力或内分泌症状明显改善;外伤性脑脊液鼻漏3例,修补后症状消失;外伤性视神经病5例,行视神经减压术后视力均有不同程度恢复;1例外伤性视神经病术后出现脑脊液鼻漏,经过保守治疗后痊愈。结论经鼻内镜鼻颅底手术具有创伤小、术后恢复快、并发症少等优点。术中正确识别颅底的解剖标志、恰当的颅底修复,有助于保证手术安全,提高手术疗效。

Objective To summarize the clinical experience with nasendoscopic surgery in nose-skull base area and explore appropriate surgical technique for various kinds lesion in this area based on a retrospective clinical analysis. Methods Included in this study were 15 patients with various kinds of nose-skull base disease, all being treated by nasendoscopic surgery during the period from Jul., 2003 to Aug., 2011. A retrospective study was carried out among them, with their clinical data analyzed carefully to sum up our experience with this kind of surgery. Results All these operations were carried out under nasal endoscope successfully. Among them, 7 with pituitary adenoma were seen with their disordered endocrine symptoms and impaired vision function improved following the surgery, 3 with traumatic cerebrospinal rhinorrhea were cured successfully without symptoms reoccurred after the operation, and 5 with traumatic optic neuropathy had improved visual function at various degrees respectively after transnasal endoscopic optic canal decompression. Among these cases with traumatic optic neuropathy, one was complicated with cerebrospinal rhinorrhea following the operation but the lesion was cured with conservative treating procedures after the primary surgery. Conclusions Transnasal endoscopic surgery holds many advantages for the treatment of lesions involving the area of nose-skull base, such as minimal invasive during the operation, quicker recovery course following the operation and fewer chance with possible operative complications. It is very important to identify the surgical anatomical landmarks exactly during the operation and to reconstruct the tissue defects in skull base properly for ensuring the safety and efficacy of the surgery.
