目的:观察颊腭侧黏膜游离结合截断牙槽窝骨板对上颌后牙拔除术所致上颌窦穿孔的干预效果。方法:选择东莞市人民医院2010年12月-2014年12月收治的62例上颌后牙拔除术所致上颌窦穿孔患者,按随机数字表法分为对照组与观察组各31例。对照组接受常规治疗,观察组则采用颊腭侧黏膜游离结合截断牙槽窝骨板进行干预。统计治疗前后两组患者颊侧前庭沟深度,观察两组术后1期愈合成功率,随访6个月,记录复瘘情况。结果:治疗后观察组颊侧前庭沟深度较治疗前无明显改变(P>0.05),对照组较治疗前明显变浅(P<0.05),两组治疗前后、颊侧前庭沟深度比较,差异具有统计学意义(P<0.05);较对照组,观察组1期愈合成功率高,术后无复瘘,两组比较,差异具有统计学意义(P<0.05)。结论:颊腭侧黏膜游离结合截断牙槽窝骨板修复上颌后牙拔除术所致上颌窦穿孔可获得理想效果,术后无复瘘,较传统疗法优势更明显。
OBJECTIVE: To observe the effect of mucosal free buccal palate combined with truncated alveolar plate on maxillary sinus perforation caused by maxillary posterior teeth extraction. Methods: 62 cases of maxillary sinus perforation caused by maxillary posterior extraction in Dongguan People’s Hospital from December 2010 to December 2014 were selected and divided into control group and observation group according to random number table. The control group received routine treatment, the observation group was the use of buccal and palatal mucosa free truncated alveolar socket intervention. The depth of the buccal vestibular groove in both groups before and after treatment was observed. The healing success rate of the first group after operation was observed. The follow-up was 6 months. The fistula was recorded. Results: The depth of the buccal vestibular groove in the observation group was not significantly changed after treatment (P> 0.05), and the control group was significantly lighter than that before treatment (P <0.05). Before and after treatment, the depth of the buccal vestibular groove was significantly different (P <0.05). Compared with the control group, the success rate of primary healing in the observation group was high and no fistula occurred after operation. The difference between the two groups was statistically significant (P <0.05). Conclusion: The combined effect of mucosa of the cheek palatal palate and the truncated alveolar plate in repairing the perforation of the maxillary sinus caused by maxillary posterior maxillary extraction can obtain the ideal result. No postoperative fistula is found, which is more obvious than the traditional therapy.
