颞下颌关节易受到多种病理的和外伤的损害使其丧失功能。颞下颌关节强直导致张口受限,咀嚼困难,影响说话和牙齿卫生。重建颞下颌关节的多种术式,包括假体置换和骨移植。这些技术没有致力于整个关节功能重建的问题。本文报告一例应用带血管的第二跖趾关节转移取代颞下颌关节和下颌升支。患者男性,33岁,4岁时双侧下颌髁状突骨折。未作即时治疗,后继发双侧颞下颌关节强直。前几年,采用多种方法治疗,均未成功。临床检查示切牙间开口度4mm。下颌后缩,并日益严重。X 线片示左颞下颌关节强直,右侧整个髁状突消失,下颌升支大部分吸收。术前,作一个上颌假体。术中先切除两侧疤痕组织,经耳前进路作右颞下颌关节骨分离,经类似进路松
Temporomandibular joint is vulnerable to a variety of pathological and traumatic damage to loss of function. Temporomandibular joint stiffness leads to limited mouth opening, chewing difficulties, affecting speech and dental hygiene. Reconstruction of temporomandibular joint of a variety of surgical procedures, including prosthesis replacement and bone transplantation. These techniques are not dedicated to the reconstruction of the entire joint function. This article reports an example of the use of a second vessel with metatarsophalangeal metatarsal joint replacement of temporomandibular joint and mandibular ascending branch. Male patient, 33 years old, 4 years old Bilateral mandibular condylar fracture. Not for immediate treatment, after secondary temporomandibular joint ankylosis. A few years ago, using a variety of methods of treatment, were unsuccessful. Clinical examination revealed incisor opening 4mm. Mandibular retraction, and increasingly serious. X-ray film showed left temporomandibular joint ankylosis, the right condyle disappeared, most of the mandibular ascending absorption. Preoperative, as a maxillary prosthesis. Surgery before the excision of both sides of the scar tissue, the right anterior mandibular advancement for the separation of the mandibular joint, the similar route into the pine
