Methods : from 1986 to 1997 , we came across 16 cases of isolated sphenoid sinusitis 方法：自1986年1997年间，本科共经历16例临床诊断为孤立性蝶窦炎病例。
When disease involves the sphenoid , the sinus can be penetrated either intranasally or through the posterior ethmoid 当病变累及蝶窦，可以经鼻内和后组筛窦进入蝶窦。
Method : thirty - two patients with pituitary tumour were treated with endoscopic transsphenoidal surgery 方法：全麻下对32例垂体瘤患者行鼻内窥镜下经鼻蝶窦垂体瘤切除术。
The natural ostium of the sphenoid sinus can usually be identified medially to the tail of the middle turbinate , approximately 1 cm above the choana 蝶窦的自然口通常位于中鼻甲的后部，后鼻孔上缘
However , the patients who were immune - compromised had poorer prognosis because of potential orbital and intracranial complications 因此对于孤立性蝶窦炎的可能性要保持警觉，才能早期诊断、早期治疗。
The patient ' s symptoms resolved following an emergency functional endoscopic sinus surgery combined with optic nerve decompression 电脑断层及核磁共振影像检查显示蝶窦有一囊状病兆，怀疑为蝶窦黏液囊肿。
Methods one hundred and twenty - six patients with pituitary adenomas were operated via endoscope - assisted direct transsphenoidal approach 方法回顾性分析126例经鼻内窥镜辅助下直接蝶窦入路显微外科垂体瘤切除手术。
Results the tumors were resected totally in 80 patients via endoscope - assisted direct transsphenoidal approach without meningitis and csf leakage 结果经鼻内窥镜辅助下直接蝶窦入路患者中有80例完全切除肿瘤组织。
Purpose : here we examine a case of sphenoid sinus mucocele presenting with left abducens nerve palsy and subsequent loss of left eye vision 摘要目的：报告一例因罹患蝶窦黏液囊肿而导致单侧外展神经麻痹及视力丧失的病例。
Conclusion the microsurgery of pituitary adenoma using endoscope - assisted direct transsphenoidal approach is safe , effective and minimally invasive 结论内窥镜辅助下直接蝶窦入路垂体瘤显微切除术是一种安全有效、微创的方法。
