Purpose: The purpose of our study was to accurately visualize and measure the normal anatomy of pterygopalatine fossa and its communications on multi-detector row CT with thin-section HRCT (0.5mm) and multiplanar reconstruction and curved planar reconstruction technologies, so as to obtain credible and comprehensive information for clinical management and basic research.

目的：采用亚毫米层厚(0.5mm)的多排螺旋CT(multidetector row CT，MDCT)高分辨扫描和多断面重建及曲面重建技术，多方位显示翼腭窝及其通连结构的正常形态并进行测量分析，以为临床诊疗工作和基础研究提供全面可靠的影像学信息。

The CT and MRI results showed soft tissue disease focus was found and its boundary was not clear, enhancement CT and MRI scanning showed 8 and 11 cases had low and middle degrees enhancement,respectively. The pathological changes in 22 cases often be outside the nasal cavity and paranasal sinus but infringed upon the pterygopalatine fossa, orbit.

CT、MRI 27例表现边界不清的软组织病灶，CT、MRI增强扫描分别为8、11例表现为低至中度强化。22例病变超出鼻腔鼻窦而侵犯翼腭窝、眼眶等窦外结构。

Results: The pterygopalatine fossa and its communications mainly displayed narrow and deformed in cases of fibrous dysplasia, the imaging anatomic characteristic were clearly and directly demonstrated in MSCT scanning images, MPR and CPR images.

结果：骨纤维异常增殖症对翼腭窝及其通道的影响主要表现为狭窄、变形，其影像解剖学变化特征在MSCT轴位扫描图像、MPR及CPR图像中得到全面、清晰、立体直观的显示。

There were two layers of tissue in the pterygopalatine fossa,they are posteromedial nerve layer and anterolateral vessel layer.The distance from the internal carotid artery to the sphenopalatine foramen was 16.4±3.3 mm.

结果：蝶腭孔、圆孔、翼腭裂距离前鼻嵴的距离分别为(62.3±2.7)、(64.2±4.8)、(51.5±0.6) mm，翼腭窝内的结构可以分为在后内的神经层和在前外的血管层，颈内动脉与蝶腭孔之间的距离为(16.4±3.3) mm。

The distance between rear part of posterior semicircular canal andanterior margin of the sigmoid sinus increased by 4.45 mm(57.8%),exposure areas ofposterior fossa dura increased by 157.32 mm~2 (64.3%)and operative angle of visionwas 329.6% that of retrolabyrinthine approach when performing PLPA approachcompared with retrolabyrinthine approach.

PLPA入路与迷路后入路相比，半规管后端与乙状窦前缘的距离较迷路后入路增加了4.45 mm (57.8%)，后颅窝硬膜的暴露面积增加了157.32 mm~2 (64.3%)，手术视角为迷路后入路的329.6%。

Results and Conclusions （1）MRI is better than CT to show the lesion of cerebellar fossa and brain stem.（2）Late radiation encephalopathy may be the result of immunal response to the damage of brain tissue and blood vessel after radiotherapy（3） 18 F-FDG-PET is a effective screenage examimation to diagnosis late radiation encephalopathy.（4）To some degree,the symptoms of the patients were alleviated after therapy with dexamethasome,mannital and vitamine B,etc.Late radiation encephalopathy ought to be given priority to prevention and treated vigorously as soon as possible.

结果和结论（1）CT对鼻咽癌迟发性放射性脑病的诊断有一定价值，但MRI对后颅窝和脑干病变的显示优于CT；（2）迟发性放射性脑病可能是放疗致脑组织血管损伤后引起免疫改变的结果；（3）18-氟代脱氧葡萄糖（ 18F-FDG）-PET是诊断迟发性放射性脑病的有效的影像学检查方法；（4）本组患者经应用激素、甘露醇、多种维生素等治疗，均取得不同程度的改善。

Methods:The bony landmarks of pterygopalatine fossa in 40 dry skulls were measured and 10 corpses (20 sides) of skull were dissected.Results:The distances from anterior nasal spur to sphenopalatine foramen,to foramen rotundum and to pterygoepalatine fissure were 62.3±2.7 mm,64.2±4.8 mm and 51.5±0.6 mm respectively.

Methods: We operated on ten adult cadaver heads(20 sides)fixed in 10% formalin by mimicking the approach combined transmastoid and middle cranial fossa under surgical microscope,exposed the facial nerve from cerebellopontine angle segment to stylomastoid foramen, the different segment and anatomic landmarks of facial nerve and its surroundings were observed and measured.
