摘要: 目的:探讨两种舌侧径路拔除下颌低位阻生第三磨牙对术后组织反应的影响。方法:136例行下颌低位阻生第三磨牙拔除术患者随机分为骨板切除术组(n=67)和骨板劈开术组(n=69),分别采用舌侧骨板切除术和舌侧骨板劈开术对患牙进行拔除。记录两组患者手术操作时间、术后疼痛、面部肿胀发生情况,比较两组患者术后48 h和7 d时张口度和吞咽痛发生情况。结果:两组患者术后均达到一期愈合。骨板劈开术组患者手术时间短于骨板切除术组,面部肿胀度小于骨板切除术组,差异均具有统计学意义(P<0.05);与术前相比,两组患者术后48 h和术后7 d张口度均减少,差异均具有统计学意义(P<0.05);骨板劈开术组患者术后48 h张口度大于骨板切除术组,而吞咽痛发生率则低于骨板切除术组,差异均具有统计学意义(P<0.05),两组患者术后7 d时张口度和吞咽痛差异无统计学意义。结论:与舌侧骨板切除术相比,骨板劈开术应用于拔除下颌低位阻生第三磨牙,可有效缩短手术操作时间,减少面部肿胀发生,对术后组织反应的影响较小。

Abstract: Objective: To investigate the effects of two pathways of lingual plates in the extraction of low impacted mandibular third molars on postoperative tissue reaction. Methods: 136 patients undergoing low impacted mandibular third molar were randomly divided into bone plate resection group (n=67) and bone plate splitting surgery group (n=69). Lingual plate resection and lingual plate splitting surgery were performed for teeth extraction, respectively. The operating time, postoperative pain and facial swelling occurrence of the two groups were recorded. At 48h and 7d after surgery, the degrees of mouth opening and odynophagia of the two groups were compared. Results: After surgery, all patients reached healing. The operation time in bone plate splitting surgery group was shorter than the bone plate resection group, and facial swelling was less than the bone plate resection group (P<0.05). At 48h and 7d after surgery, the degrees of mouth opening in the two groups were reduced (P<0.05). At 48h after surgery, the degree of mouth opening in bone plate splitting surgery group was greater than the bone plate resection group, and meanwhile the occurrence of odynophagia was less (P<0.05). At 7d after surgery, the differences in the degree of mouth opening and odynophagia between the two groups were not significant. Conclusion: Compared with lingual plate resection, lingual plate splitting surgery used in the extraction of low impacted mandibular third molars could effectively reduce the operation time and the occurrence of facial swelling, accompanied by less postoperative tissue reaction.
