| 内容記述 | We examined changes in the pharyngeal airway space of skeletal open bite patients receiving orthodontic treatment. To compare jaw relationships, the position of the hyoid bone and pharyngeal airway space were examined for each case using sets of three lateral cephalometric radiographs that were taken before treatment (A1), after treatment (A2) and for control (N). Craniofacial skeletal measurements revealed no significant differences in ∠SNA between Groups A1 to A2. Although ∠SNB and the ∠MP showed a slight increase between Groups A1 and A2, the difference was not significant. Measurements of the cervical vertebrae, tongue and velum revealed that HSN and S-H were significantly greater in Group A1 than in Group N. Both HSN and S-H increased significantly between Groups A1 to A2. C3-H in Group A1 was significantly less than in Group N, and showed a significant decrease between Groups A1 and A2. ∠SP was significantly less in Groups A1 and A2 than in Group N. No significant difference was seen between themeasurements of Groups A1 and A2. The values for D1 in Groups A1 and A2 were significantly greater than for Group N. There were significant differences between Groups A1 and A2. Measurements of the superior posterior pharyngeal airway space, SPPS, and the middle pharyngeal airway space, MPS, in Group A1 were significantly less than in Group N, indicating a narrowing of the pharyngeal airway width. SPPS and MPS in Group A2 were significantly decreased compared with Group A1, indicating a narrowing after treatment. There were no significant differences in the palatal pharyngeal space, PPS, and the epiglottic pharyngeal space, EPS, in Groups A1 and A2, respectively. These results suggest that the pharyngeal airway space decreased after orthodontic treatment of skeletal open bite caused by posterior inclination of the soft palate. |
