Objective·To analyze the anatomical and macroscopic characteristics of the pterygopalatine suture (PPS) in Chinese population using cone-beam computed tomography (CBCT) technology, and to preliminarily investigate its developmental pattern and its association with the correction of maxillary underdevelopment.Methods·A total of 134 CBCT images, taken from July to August 2023 at Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, were categorized into six age groups. The PPS landmarks were utilized to determine the overall transverse position (XPPS), sagittal position (YPPS), insertion angle (IAP), insertion width of the pyramidal process (IWP), and insertion depth of the pyramidal process (IDP). The pterygomaxillary junction was identified through multiplanar observations. Regression analysis was performed to assess the correlation of these parameters with age and gender, and pairwise comparisons were made to determine the stable age range for parameter changes.
