牙齿或牙根进入上颌窦应当立即取出。作者介绍了一种手术方法,称为穿过牙槽进路法。首先在拔牙牙槽窝颊侧形成一个梯形粘骨膜瓣。用骨钳去除牙槽颊侧骨板直到牙槽窝底,并在其上方形成1厘米直径的开口,暴露出上颌窦粘膜。探查断根是否穿过上颌窦粘膜,如果上颌窦粘膜完好,应仔细探查粘膜下,骨膜下或颊部软组织内有无断根。若上颌窦粘膜已破,断定牙根已落入上
Teeth or root into the maxillary sinus should be immediately removed. The authors describe a surgical procedure called the method of passage through the alveolar space. First of all, a trapezoidal mucoperiosteal flap is formed on the buccal side of the tooth extraction socket. The alveolar buccal bone plate was removed with the pliers until the bottom of the alveolus, and a 1 cm diameter opening was formed over it to expose the maxillary sinus mucosa. To explore whether the root cut through the maxillary sinus mucosa, if the maxillary sinus mucosa intact, should be carefully investigated submucosal, subperiosteal or buccal soft tissue with or without root. If the maxillary sinus mucosa has been broken, concluded that the root has fallen into
