方法: 本法可在局麻或全麻下进行。作者认为在局麻前给以适量的安定(Valium)和地美罗(Demeral)静脉注射能取得满意的麻效。在额弓骨折区用2%利多卡因作口外注射;口内则用2%利多卡因、1:100,000肾上腺素于切口处的粘膜和颧弓内侧及下方深层软组织作局部浸润麻醉。然后在复盖喙突和下颌枝前缘的粘膜上,从上颌牙槽平面开始向下沿着下颌枝前缘作4厘米长的切口(图1)。切口要深达骨膜。用弯剪或中号弯形止血钳沿喙突外侧和上方行钝性分离,经过颞肌腱及颞肌,一直到达颧弓骨折处,此时分离器 Method: This method can be carried out under local anesthesia or general anesthesia. The authors believe that satisfactory anesthetic efficacy can be obtained by administering intravenous Valium and Demeral in appropriate amounts before local anesthesia. 2% lidocaine was used for oral injection in the frontal arch fractures; 2% lidocaine was used in the mouth, while 1: 100,000 epinephrine was applied to the mucosa at the incision and deep soft tissue inside and below the zygomatic arch for local infiltration anesthesia. Then a mucosa covering the coracoid process and the leading edge of the mandibular incision was made 4 cm long incision down the leading edge of the mandibular branch from the maxillary alveolar plane (Figure 1). Cut deep to the periosteum. With curved or moderate curved hemostatic forceps along the lateral and superior coracoid line blunt dissection, after the temporal tendon and temporal muscle, has reached the zygomatic arch fracture, this time separator
