Craniofacial morphology and head posture in Chinese subjects with obstructive sleep apnea

摘要: This study measured craniofacial and head posture variables from standardized lateral cephalometric radiographs in Chinese subjects with obstructive sleep apnea (OSA) referred to a university hospital. The investigation was performed the Sleep Laboratory of Department Respiratory Medicine, National University Singapore. sample consisted 61 male subjects, 25 mild 36 moderate-to-severe OSA diagnosed using overnight polysomnographic studies. Standardized were used record linear angular dimensions for morphology. compared group, as ethical reasons no control group available. Significant differences found between hyoid positions samples OPA. more caudally placed when mandibular border (ML; P < 0.05) maxillary plane (NL; 0.01). No significant other measured, but anterior cranial base shorter, angle smaller, gonial greater sample, this did not reach level significance. There also values recorded variables, so data pooled existing published studies both white subjects. revealed marked increase craniocervical angulation (P 0.001) total craniovertical (NSL/VER), (NSL/OPT), craniohorizontal (OPT/HOR) each various groups. provides evidence that caudal bone position are OSA.
