蝶窦病变因临床表现较少而不易肯定,且解剖位置特殊,致使蝶窦炎诊治有很大困难。实际上蝶窦炎要比过去所认为的更多见。传统的鼻镜检查和X线照片不能满足诊断要求,蝶窦探查与穿刺虽大大增加了诊断可能性,但即使对有经验的医生来说,这一操作也是困难和危险的。穿刺的最合适点是窦口的邻近部位。但由于可能存在着窦的解剖变异、窦内有嵴和囊袋之类的结构异常、鼻甲肥大、中隔嵴或偏曲,都会妨碍直视蝶窦前壁,故应寻求一种简便、安全的穿刺定位法。
Due to the clinical manifestations of sphenoid sinus lesser but not easy to affirm, and the special anatomical location, resulting in the treatment of sphenoid sinusitis have great difficulties. In fact, sphenoid sinus than the past think more. Traditional nasal examination and radiographs do not meet the diagnostic requirements, sphenoid sinus exploration and puncture, although greatly increased the possibility of diagnosis, but even for experienced doctors, this operation is also difficult and dangerous. The most suitable puncture point is the ostium of the adjacent parts. However, due to possible anatomical variations of the sinus, structural abnormalities such as ridges and capsular sacs in the sinus, hypertrophy of the turbinate, septal crest or skewed curvature, which may prevent direct viewing of the anterior sphenoidal wall and should therefore be sought for simplicity, safety Puncture positioning method.
