Abstract：
Obstructive sleep apnoea (OSA) is identified as repetitive and intermittent upper airway collapse or narrowing during sleep. Skeletal advancement through maxillomandibular surgery remains the most effective surgical treatment for OSA but is radical with certain relapse rate. Distraction Osteogenesis of mandible is a single-jaw surgical treatment alternative to bi-jaw surgeries having lesser complications. This case report describes successful management of a 46-year-old patient who reported with a chief complain of obstruction in breathing while sleeping since one year. Obstructive Sleep Apnoea (OSA) secondary to a retrognathic mandible was the final diagnosis, which was successfully treated by Distraction Osteogenesis (DO) of the mandible. The case showed enhancement in airway by 13mm and marked forward movement of Point-B (SNB increased by 6 degrees). The Epworth Sleepiness Scale value decreased from 19mm to 8 mm indicating substantial increase in the airway with stable results after 18 months of follow-up (elimination of symptoms and subsequent sound sleep). Distraction osteogenesis is an effective and reliable method to treat obstructive sleep apnoea secondary to retrognathic mandible.
摘要：
阻塞性睡眠呼吸暂停(OSA)被确定为睡眠期间的重复性和间歇性上呼吸道塌陷或狭窄。通过上颌下颌手术进行骨骼前移仍然是OSA最有效的手术治疗方法，但具有一定的复发率。牵引下颌骨成骨是一种单颌手术治疗方法，可替代双颌手术，并发症较少。该病例报告描述了一名46岁患者的成功治疗，该患者自一年以来一直抱怨睡觉时呼吸阻塞。最终诊断为下颌后下颌骨继发的阻塞性睡眠呼吸暂停（OSA），通过下颌骨的牵引成骨（DO）成功治疗。病例显示气道增强13mm，B点明显前移（SNB增加6度）。Epworth嗜睡量表值从19mm降至8mm，表明在18个月的随访（症状消除和随后的良好睡眠）后，气道显着增加，结果稳定。牵张成骨是治疗下颌下颌后继发的阻塞性睡眠呼吸暂停的有效且可靠的方法。
