口腔上颌窦瘘临床修补方法较多,效果多半不够理想。自1992年7月以来,作者采用人工骨粉修补骨性缺损组织4例,随访1~3年,效果较为满意。手术方法1．患者取仰卧垂头位,充分暴露患侧上颌磨牙,局麻后,先测好所需粘骨膜大小,做成基底向后的宽蒂腭大动脉粘骨膜瓣。细心磨除或凿除腭大孔至瘘管口侧壁部分骨壁,成呈沟槽状,以便蒂瓣转位时,血管仍沿直线向侧向前。2．清除瘘道内的肉芽组织,暴露新鲜骨创面。取瘘口周部分骨片或软组织大小合适,置人上颌窦腔的瘘口处,以防骨粉滑人窦腔。再用生理盐水将人工骨粉浸湿成细砂状,用小匙将其填满瘘道并压紧。
Oral maxillary sinus fistula clinical repair methods are more, the effect is not ideal enough. Since July 1992, the authors used artificial bone powder to repair 4 cases of bone defect, followed up for 1 to 3 years, the effect is more satisfactory. Surgical methods Patients supine down bit, fully exposed ipsilateral maxillary molars, local anesthesia, the first measure the required mucoperiosteal size, made of the base of the back of the wide pedunculated aortic periosteal flap. Carefully removed or chisel fistula fistula to the wall of the foramen wall part of the bone wall, into a groove-shaped, so that pedicle transposition, the blood vessels are still straight along the side to the front. 2. Remove the fistula granulation tissue, exposed fresh bone wounds. Take the fistula perioral bone or soft tissue size appropriate, placed in the maxillary sinus fistula Department, to prevent bone powder sliding sinus cavity. And then use artificial saline soaked artificial bone powder into a fine sand shape, fill it with a small spoon fistula and compressed.
