根据100例经鼻蝶窦手术患者的头颅X线平片、矢状断层和冠状CT扫描片,以及手术中直接观察的结果,仔细研究了蝶窦的气化类型,提出一种新的两侧组合分型法。发现相同型蝶窦占58％,不同型占42％,前者进一步分为5个亚型,后者可分为10个亚型。强调此种分型法对经鼻蝶窦手术时选择合适的进路具有重要意义。蝶上筛房的出现率为22％,如果手术者不熟悉它的解剖,术中易将其误认为蝶窦,而误伤颈内动脉和视神经等。
Based on the skull radiographs, sagittal and coronal CT scans of 100 patients with nasal and sphenoid sinus surgery and direct observations during surgery, the types of gasification in the sphenoid sinus were carefully studied and a new bilateral Combination typing method. Found that 58% of the same sphenoid sinus, 42% of different types, the former is further divided into five subtypes, the latter can be divided into 10 subtypes. Emphasize that this type of method for transnasal sinus surgery to choose the right path is of great significance. Butterflies on the screen room rate of 22%, if the surgeon is not familiar with its anatomy, intraoperative easy to mistaken for sphenoid sinus, and accidental injury of the internal carotid artery and optic nerve.
