下颌支矢状劈开截骨术后下唇感觉功能障碍对生活质量的影响

目的研究下颌支矢状劈开截骨术(sagittal split ramus osteotomy,SSRO)术后下唇感觉功能障碍对患者生活质量的影响及其程度。方法2004年9月~2005年9月,对采用SSRO治疗的21例患者进行问卷调查。男12例,女9例;年龄19~27岁,平均22.6岁。于术后4周及24周随访,根据随访结果比较患者术后生活质量恢复情况。结果术后4周,19例(90.48%)患者因SSRO术后下唇感觉障碍而导致生活质量下降;其中7例(33.33%)患者生活质量受到严重影响;对日常生活的平均影响时间占总时间的26.9%,约6.5h/d。术后24周,因术后下唇感觉障碍而致生活质量下降的患者总数下降为12例(63.16%),无影响患者上升至7例(36.84%);平均影响时间降至15.5%,约3.7h/d。结论大部分患者在SSRO术后会产生因下唇感觉功能障碍致生活质量下降。但此种情况在术后逐渐好转,有1/3以上患者可在术后24周恢复至术前生活质量。

EFFECT OF SENSORY DISTURBANCE ON LIVING QUALITY AFTER A SAGITTAL SPLIT RAMUS OSTEOTOMY

Objective To evaluate the effect of sensory disturbance after the sagittal split ramus osteotomy (SSRO)on quality of life. Methods From September 2004 to September 2005, 21 patients undergoing SSRO were studied by using questionnaires. There were 12 males and 9 females, aging 19-27 years(mean 22.6 years).The patients were followed up at 4 weeks and 24 weeks after operation. The subjective questionnaire was completed by patient to evaluate the degree of living quality descending. Results At 4 weeks,19(90.48%) patients' living quality descended because of postoperative sensory disturbance. Among them, 7(33.33%) patients had severe descending of living quality. The average effecting time of living accounted for total time 26.9%(about 6.5 h/d). At 24 weeks, 12(63.16%) patients' living quality descended because of postoperative sensory disturbance, 7(36.84%) patients could achieve preoperative living quality. The average effecting time of living accounted for total time 15.5%(about 3.7 h/d). Conclusion Most patients have descending of living quality after SSRO because of sensory disturbance. However, this condition can be improved during the follow-up and more than 1/3 patients can achieve their preoperative living quality.
