Title: Three-dimensional sectional anatomy of pterygopalatine space
Abstract: Objective:To provide anatomical data for imaging diagnosis of the pterygopalatine space disease.Meth- ods:The heads and necks of adult corpses were cut into the transverse,sagittal and coronal sequence sections. Pterygopalatine space and its structure were observed and its diameter and area were measured with vernier cali- per and planimeter.Results:Pterygopalatine space displayed different shapes,and the shape was stable at the sphenoinal body level on transverse section,which was relative to the pterygoid process.Pterygopalatine space and its structure were symmetrical of both sides.There was no significant difference in diameter and area.The anterior,posterior,medial and lateral wall of pterygopalatine space and its communication paths,including the foramen rotundum,pterygoid canal,sphenopalatine foramen,pterygomaxillary fissure and inferior orbital fissure were clearly displayed on transverse section.The succession of the pterygopalatine canal,greater palatine canal and lesser palatine canal was displayed on sagittal section.The hanging wall of the pterygopalatine space,fora- men rotundum,inferior orbital fissure,pterygoid canal and its relationship with the sphenoidal sinus were dis- played on coronal section.Conclusion:Our results indicate three-dimensional sectional anatomy of the pterygopal- atine space is important for imaging diagnosis.
