Abstract：Objective To provide the anatomic basis for the surgery of pterygopalatine fossa through maxillary sinus. Methods The distances from the sphenopalatine foramen, ethmoidal crest to anterior nasal spine and mid-sagitral plane were measured in 20 adult dried skull specimens. The anatomical features and data of sphenopalatine foramen, ethmoidal crest, foramen rotundum, canalis pterygopalatinus and pterygoid canal were studied. The appearances of these structures under microscope and nasal endoscope were also observed. Results The height of pterygomaxillary fissure was(15.30±0.43)mm, the anteroposterior diameter of sphenopalatine foramen was (5.10±1.84)mm, the superoinferior diameter of sphenopalatine foramen was (5.09±1.53)mm, the distance from sphenopalatine foramen to mid-sagitral plane was (12.49±1.51)mm, the distance between sphenopalatine foramen and anterior nasal spine was(51.32±3.28)mm, the diameter of foramen rotundum was (3.14±1.26)mm, the distance from foramen rotundum to mid-sagitral plane was (19.95±2.79)mm, the distance between foramen rotundum and anterior nasal spine was (61.86±3.67)mm, the distance from pterygoid canal to mid-sagitral plane was (10.82±2.98)mm, the distance between pterygoid canal and anterior nasal spine was (59.47±3.42)mm. Conclusions Our study can provide the anatomical parameters for the surgery of pterygopalatine fossa under nasal endoscope.
