目的探讨上颌磨牙拔除过程中牙根坠入上颌窦的取出方法。方法回顾性分析2007年1月至2013年1月辽宁省抚顺市中心医院口腔科收治的上颌磨牙拔除过程中牙根坠入上颌窦内采用传统手术方法取出病例31例,2012年1月至2013年6月用微创方法在内窥镜辅助下取出坠入上颌窦内牙根病例13例。随诊观察其长期并发症并评价患者对手术效果的满意度。结果随访1~3年,采用传统方法的31例中有10例出现不同程度的面部肿胀、术区自发性钝痛等长期并发症,3例患者出现上颌窦瘘复发,对手术效果不满意;应用内窥镜辅助下取出上颌窦内牙根的13例,无一例出现长期并发症,均对手术效果满意。结论用传统手术方法取出上颌窦内牙根,术后长期并发症发生率较高;内窥镜下取出上颌窦内牙根是一种微创的、效果良好的方法。
Objective To investigate the method of extraction of maxillary sinuses from the roots during maxillary molar removal. Methods A retrospective analysis of 31 patients with tooth root crashed into the maxillary sinus during the removal of maxillary molars received at the Department of Stomatology, Central Hospital of Fushun City, Liaoning Province from January 2007 to January 2013 was performed by traditional surgical methods. From January 2012 to 2013 June with minimally invasive method in the endoscope assisted cataract extraction in the maxillary sinus root in 13 cases. Followed up to observe its long-term complications and evaluate the patient’s satisfaction with the effect of surgery. Results One to three years of follow-up, 10 of the 31 patients with traditional methods had long-term complications such as facial swelling and spontaneous dull pain in the operation area. The recurrence of the maxillary sinus fistula in 3 patients was unsatisfactory. Thirteen cases of maxillary sinus root were removed with the help of endoscope. None of them had long-term complications, which were satisfactory to the operation. CONCLUSION: The root canal of the maxillary sinus is removed by traditional surgical methods. The incidence of long-term complications is high. Removal of maxillary sinus root by endoscopy is a minimally invasive and effective method.
