Abstract
The aim of this study was to evaluate the distance from descending palatine canal to the piriform rim and pterygomaxillary junction in Thai orthognathic surgery patients. Cone beam CT images of 96 Thai patients who underwent Le Fort I osteotomy were measured the length from the piriform rim to the most anterior point of the descending palatine canal and the length from the most posterior point of the descending palatine canal to the pterygomaxillary fissure. The images were categorized according to sex, side, skeletal Class I, II, and III. The mean distances between the piriform rim and the most anterior point of the descending palatine canal were 36.00 (±2.87) mm. The mean distances between the most posterior point of the descending palatine canal and the pterygomaxillary fissure were 2.32 (±0.74) mm. There were no significant difference in any measurements between sex, side, and skeletal patterns in a group of Thai orthognathic surgery patients.
