摘要
目的研究断根误入上颌窦后利用牙槽窝通路,使用内窥镜诊断及取断根的方法。方法对在拔牙过程中怀疑牙根断入上颌窦的13例病例,使用内窥镜进行诊断,对于明确断根完全进入上颌窦的病例行经牙槽窝直视下取出断根,同时行牙龈黏膜减张严密缝合。对于断根未进入上颌窦的行保守治疗。结果 13例患者中有7例为完全进入上颌窦,采用内窥镜从牙槽窝进入,均成功取出断根。13例病例术后1月黏膜愈合良好,均未出现口腔上颌窦瘘。术后3月除1例患者失访,其余牙槽窝愈合良好。结论利用内窥镜扩大视野可准确判断牙根是否完全进入上颌窦。采用经牙槽窝扩大内窥镜取根法可以在直视下取出进入上颌窦的断根,创伤小,术后恢复良好,是一种微创、快捷的方法。
Objective To study the diagnosis and extraction of broken roots in maxillary sinus through alveolar cavity by endoscopy. Methods To the 13 cases, endoscopic diagnosis was made. Some broken teeth roots completely dislocated into maxillary sinus were extracted under endoscopy. Perform tension-reduced suture to gum mucosa. Other cases whose broken teeth didn＇t get into maxillary sinus were treated conservatively. Results 7 out of 13 roots were dislocated into maxillary sinus completely and were removed successfully through alveolar cavity under endoscopy. Good mucosal healing was achieved in the 13 cases one month ＇after the treament. There was no fistula of maxillary sinus found in all of patients. 1 case was missed in the follow-up visit 3 month after treatment, and the alveolar cavity of the rest cases healed well. Conclusions Endoscopy can be used to broaden vision for accurate diagnosis whether the broken roots were dislocated into maxillary sinus completed. The treatment about removal of broken teeth roots through alvolar cavity under endoscopy is efficient,less invasive and quick.
