Abstract

This study was performed to aid for the case analysis and diagnosis of the maxillofacial deformities. A cephalometric analysis was made from 101 subjects over 18 years old, that consisted of 46 males and 55 females with normal occlusion, acceptable profile. The results o f this study were obtained as follows: 1. The tables of normals in adult male and female were made. 2. The angles of SNO were $65.5^{\circ}$ in male and $65.3^{\circ}$ in female and the horizontal linear measurements from 0 to NA(O-NA) were 9.0 mm in male and 8.9 mm in female. 3. The cranial base angles (SN-FH) were $8.2^{\circ}$in male and $10.3^{\circ}$ in female and the mandibular plane angles (OP-HP) were $28.1^{\circ}$ in male and $26.2^{\circ}$ in female. 4. The correlation of (O-NA) to S-O/S-A and S-O/S-N were higher than SNO, and the correlation of (N-A) to SNA and (N-B) were high.
