下颌阻生智齿拔除术中移位至舌下间隙(附病例报告8例)

Mandibular Impacted Wisdom Teeth Displaced into Sublingual Space:Report of 8 Cases

目的:探讨牙拔除术中移位于舌下间隙的下颌阻生智齿的治疗方法。方法:收集2014年1月~2019年4月下颌阻生智齿拔除术中牙或牙根移位进入舌下间隙的8例病例,通过临床及影像学检查对其定位,局部麻醉下行牙槽窝近远中松弛切口,舌侧翻瓣取出移位牙,对其进行总结分析。结果:8例患者均成功取出移位的牙或牙根。3月后回访,拔牙创口愈合良好,无明显并发症。结论:通过临床及影像学检查定位,行牙槽窝近远中松弛切口舌侧翻瓣,可取出移位于舌下间隙的下颌阻生智齿。

Objective:To review the therapeutic methods of the displaced mandibular impacted wisdom teeth.Methods:8 cases of displaced teeth during the extraction of third molars from January 2014 to April 2019 were reviewed.Bimanual palpation and image examination were used to locate the displaced teeth.Relaxation incisions were made distally and medially of the extraction sockets under local anesthesia,then mucoperiosteal flaps were raised to retrieve the teeth.Results:8 displaced teeth were successfully managed.3 months later,the wound healed well and the post-operative recovery was uneventful.Conclusion:Through bimanual palpation and image examination,relaxation incisions at the distal and mesial sides of the extraction sockets were useful to retrieve the displaced teeth.
