To provide anatomic data of pterygopalatine fossa(PPF) for endoscopic PPF surgery.
Fifteen wet adult skull specimen fixed in 10% formaldehyde were studies. From center the skulls were sawed, the middle and inferior turbinate were resected, the anterior and posterior ethmoid sinuses were resected. Then after punch out perpendicular part of palatine bone and posterior wall of maxillary,the pterygopalatine fossa were showed and some related measurements were made.
This pathway can lead to a good view of pterygopalatine fossa. The main soft structures in PPF were maxillary artery and nerve with their branches. The diameter of artery branches was smaller than 3 mm.
The endoscopic PPF surgery is safe and practical from the anatomic data.
为翼腭窝（PPF）内镜手术提供解剖学数据。
研究15例用10%甲醛固定的成人湿性颅骨标本。从颅骨中心锯开，切除中鼻甲和下鼻甲，切除前后筛窦。然后凿除腭骨垂直部和上颌后壁后，显露翼腭窝并进行一些相关测量。
此入路可良好显示翼腭窝。翼腭窝内主要的软组织是上颌动脉及其分支神经。动脉分支直径小于3mm。
从解剖学数据来看，翼腭窝内镜手术是安全可行的。
