頬部骨折新鮮例の観血的治療

抄録

Three cases of so-called tripod malar fracture were treated by maxillary antrostomy for reduction and zygomatico-palatal Kirschner wire fixation (Matsunaga¹⁾). Under general anesthesia, a mucosal incision was made in the gi.ngivobuccal sulcus, and the anterior surfaces of the maxilla and zygoma were exposed. The bulk of the malar bone was reduced by an elevator and then fixed by the Kirschner wire driven from its lateral aspect aimed obliquely through the antrum towards the hard palate. The wire was left in place for four to five weeks and then removed under local anesthesia through a small skin incision made over the wire. Reduction and fixation were satisfactory in all three, and the facial scar was minimum.
Zygomatico-palatal Kirschner wire fixation is considered to be a safe and simple method of treating malar bone fractures.
