本文介绍一种带蒂的粘骨膜-骨瓣,修补牙源性上颌窦炎合并口腔上颌窦瘘。经临床观察效果良好,现报告如下。手术方法在瘘孔的颊侧做一类似倒梯形切口,近中切口略呈弧形,并达到尖牙凹处。远中的切口则根据瘘口的部位和瘘口的远中是否有牙齿来决定。将瘘口周缘形成新的创面,用平凿与骨钻将瘘孔的颊侧骨壁连同粘骨膜一并掀起,形成粘骨膜-骨瓣。骨瓣大小根据瘘孔而定。然后,将粘骨膜瓣继续向上掀起,达尖牙凹区。暴露骨面,行上颔窦开窗及根治术。用碘仿纱条填塞窦腔,对孔引流。最后修整粘骨膜-骨瓣,使其形态适合修补瘘口,缝合创口并行适
This article describes a pedicle of mucoperiosteal - bone flap to repair odontogenic maxillary sinusitis with oral maxillary sinus fistula. The clinical observation of good results, are as follows. Surgical methods in the buccal fistula hole to do a similar inverted trapezoidal incision, near the incision slightly arcuate, and reached the canine pit. Far in the incision is based on the location of the fistula and the distal fistula to determine whether the teeth. The fistula around the formation of a new wound, with flat chisel and bone drilling fistula buccal bone wall together with mucoperiosteal lining set off, forming mucoperiosteal - bone flap. Bone size according to fistula hole. Then, mucoperiosteal flap will continue to rise up to the canine concave area. Exposure of bone surface, line stenosis sinus surgery and radical mastectomy. Fill the sinus cavity with iodoform gauze and drain the hole. Last trimming mucoperiosteal - bone flap, make its shape suitable for repair fistula, suture wound parallel
