上颌窦根治术,由于凿除上颌窦前壁,有时瘢痕组织长入上颌窦内,形成阻塞,甚至引起上颌窦炎复发。为克服这种缺点,该作者使用自体复合移植片进行上颌窦前壁成形术:口内切口,掀起粘骨膜瓣,在上颌窦前壁用钻和锯取下横的长方形的带上颌窦粘膜的复合骨片约1.5×3.0cm,用盐水纱布包盖保存,清除上颌窦病变,下鼻道作对孔,然后把复合骨片呈竖位搭在上颌窦开窗的上、下缘骨面上,骨钻孔缝合固定,缝合粘骨膜瓣。
Maxillary sinus radical surgery, due to excision of the anterior wall of the maxillary sinus, and sometimes the growth of scar tissue into the maxillary sinus, the formation of obstruction, or even cause maxillary sinusitis recurrence. To overcome this drawback, the authors used an autograft graft for maxillary anterior walloplasty: an intraoral incision, a mucoperiosteal flap, and a transverse, oblong composite with maxillary sinus mucosa removed with a drill and saw in the anterior wall of the maxillary sinus Bone pieces about 1.5 × 3.0cm, covered with saline gauze cover, remove the maxillary sinus lesions, the lower nasal passages for the hole, and then take the vertical bone composite jaw open in the maxillary sinus window, the lower edge of the bone surface, bone drilling Hole suture fixation, suture mucoperiosteal flap.
