Abstract:Objective To observe pterygopalatine space and its paths on the CT image and sectional specimens, provide the basis for imaging diagnosis and surgical approach for the diseases of pterygopalatine space. Methods The CT image of 40 adult volunteers with no abnormalities of the pterygopalatine space and its paths were selected, and reconstructed by the multiplanar reformation (MPR) in our hospital from March 2012 to January 2013. Thirty heads and necks of adult corpses were selected and cut into transverse, sagittal and coronal sequence section respectively. Pterygopalatine space and its paths were observed and measured in the length and width on the CT imaging and sectional specimen. Results It was better to show the anterior, posterior wall of pterygopalatine space and its paths, including pterygoid canal, sphenopalatine foramen and pterygomaxillary fissure on transverse section of CT image and sectional specimens. To show succession of the foramen rotundum, pterygopalatine canal and greater palatine canal, less palatine canal on sagittal section. It was helpful to observe the medial, superior wall of pterygopalatine space, inferior orbital fissure, pterygoid canal and the relationship of it to the sphenoidal sinus. Its shapes of pterygopalatine space were immovable through the sphenoinal body on transverse section. They were (6.16±0.65)mm and (6.22±0.44)mm in posteroanterial diameter, (23.10±1.16)mm and (23.34±0.67)mm in medialateral diameter of the pterygopalatine space, respectively. Pterygopalatine space and its paths were symmetrical. There were no significant difference in the diameter except the posteroanterial diameter of inferior orbital fissure on the CT image and sectional specimens(P>0.05). Conclusions It can clearly show the anatomical relationship of pterygopalatine space and its paths on different orientations of the CT image and sectional specimens, it has an important clinical significance for imaging diagnosis and surgical approach of the diseases of pterygopalation space.
