目的探讨经鼻蝶入路垂体瘤切除术后并发蝶窦炎的防治方法。方法 129例患者行经鼻蝶入路垂体瘤切除术,统计术后并发蝶窦炎患者,对其进行处理。结果经鼻蝶入路垂体瘤切除术后并发蝶窦炎6例(4.65%),经鼻内镜下定期术腔清理、鼻用激素、鼻腔冲洗后全部治愈。结论对经鼻蝶入路垂体瘤切除术后并发蝶窦炎患者行鼻内镜下及时处理,可有效改善患者临床症状。 Objective To investigate the prevention and treatment of sphenoid sinusitis after pituitary adenoma resection through nasalis patellar approach. Methods A total of 129 patients underwent resection of the pituitary tumor with nasalis patellar approach. The patients with sphenoid sinusitis were treated after the operation. RESULTS: Six cases (4.65%) of sphenoid sinusitis were treated by nasal sphenoid pituitary adenoma after resection of the pituitary tumor. All the patients were cured by intranasal endoscopic surgery, nasal hormones and nasal irrigation. Conclusions The nasal endoscopic pituitary adenoma after resection of patients with sphenoid sinusitis under timely endoscopic treatment can effectively improve the clinical symptoms of patients.
