文献中曾描述过多种不同的暴露髁状突的进路。如果需要暴露颧弓前份,耳前进路则特别有用,但由于切口向前延伸,面神经额支可因组织的牵拉损伤而致暂瘫。由耳内进路仅能提供有限的通道。虽然近年来新兴的应用耳后进路的方法没有这种有限通道的缺点,但由于软骨性听道被切断,可导致耳道的挛缩和狭窄。当存在广泛的关节粘连时,颌下切口是有用的;当骨折或脱位致使髁状突前移时,由口内进路是有利的。由耳道周围进路可通过耳前和耳后的联合切口进入关节凹区域。因为其前方的组织未被过度牵引,故不致发生面神经额支的损伤。切口的耳前部分可在无血管平面直接深入到软骨性听道。耳前和耳后的切口在分离骨膜后于颧弓根部上方相联接。关节凹外 Various different approaches to expose the condyle have been described in the literature. If you need to expose the anterior zygomatic arch forward, the ear before the road is particularly useful, but because the incision extends forward, facial nerve branch due to tissue stretching injury caused paralysis. Only limited access is provided by the intra-aural approach. Although the emerging approach to the posterior approach in recent years has not had the disadvantage of this limited access, the contracture and stenosis of the ear canal can result from the cut off of the cartilaginous auditory canal. Submandibular incisions are useful when there is a wide range of articular adhesions; intraoral approaches are advantageous when the condyle is advanced due to fracture or dislocation. The approach around the ear canal can enter the concave area of ​​the joint through the joint incision in the front of the ear and behind the ear. Because the front of the organization is not over-traction, it will not occur facial nerve branch damage. The anterior part of the incision can penetrate directly into the cartilaginous tract in the avascular plane. Anterior and posterior ear incision in the separation of the periosteal zygomatic arch above the top of the connection. Joints concave
