We report a 16-year-old pubescent pediatric patient with obstructive sleep apnea syndrome (OSAS) and short stature whose apnea hypopnea index (AHI) was significantly reduced following the use of an orthodontic oral appliance that advances the mandible ventrally. The mandible was advanced 64% of the maximal mandibular protrusive position with use of the appliance over a 3-year period. The patient's AHI without the appliance in place decreased from 101.6/h at baseline to 11/h after treatment. Moreover, the patient's height increased 14 cm during treatment, resulting in height close to the average height for his age. Cephalometric analysis revealed an improvement in his retrognathic mandible and proclination of the upper front teeth. In conclusion, an orthodontic mandibular advancement oral appliance played an important role not only in improving the patient's OSAS but also in normalizing his physical growth during puberty.
我们报告了一例 16 岁青春期患有阻塞性睡眠呼吸暂停综合征（OSAS）和身材矮小的患者，使用颏舌肌向前牵引下颌的口腔矫治器后，其呼吸暂停低通气指数（AHI）显著降低。在 3 年的时间里，该患者使用该矫治器将下颌前伸 64%，达到最大下颌前伸位置。患者在未使用矫治器时的 AHI 从基线时的 101.6/h 降至治疗后的 11/h。此外，在治疗期间，患者的身高增加了 14 厘米，接近其年龄的平均身高。头影测量分析显示，其下颌后缩和上颌前牙前倾得到改善。总之，口腔矫治器颏舌肌向前牵引下颌不仅对改善患者的 OSAS 具有重要作用，而且对青春期的正常生长发育也具有重要作用。
