用于严重的面中1/3发育不足患者的上颌颧骨切开术可有口内口外两种类型的切口,而传统和其它变异的口内法上颌颧骨切开术虽然照顾了美观,却可能引起眶下神经损伤,眶周组织嵌入上颌窦及上颌窦前壁骨折等并发症。 本文介绍的改进的上颌颧骨切开术,在前庭沟做切口从一侧上颌磨牙区至对侧,翻起粘骨膜瓣,显露上颌的前外侧壁,朝着颧骨支柱和颞骨颧突向外上方解剖,找出眶下神经,使用弯曲的骨膜剥离器分离至眶底。用来复锯或骨钻从梨状孔外侧面到眶下缘内侧面作骨切开,第二磨牙骨切开线从眶下缘外侧方到颧突的最后面,用骨凿完成此骨切开,斜向后方和侧方以便
For the maxillofacial zygomatic incision in one-third of severely nocturnal patients, there may be two types of incision in mouth and mouth, while the traditional and other variant intra-oral maxillary zygomatic incision may be aesthetically pleasing but may Infraorbital nerve injury, periorbital tissue embedded maxillary sinus and maxillary sinus anterior wall fractures and other complications. This article describes the improved maxillary zygomatic incision in the vestibular groove incision from one side of the maxillary molar area to the contralateral, flip mucoperiosteal flap, revealing the anterior lateral wall of the maxillary, toward the zygomatic strut and temporal bone zygomatic process Outer upper anatomy to find the infraorbital nerve, the use of curved periosteal dissection to the orbital floor. Used for complex sawing or bone drilling from the lateral side of the hole to the medial infraorbital margin for osteotomy, the second molar incision line from the lateral side of the infraorbital margin to the back of the zygomatic process, complete with osteotome Cut, slant back and sideways so
