During the past 10 years, more than 20 patients a year have been treated at our centre for bilateral ankylosis of the temporomandibular joint (TMJ). Here we describe the use of computer-assisted three-dimensional surgical planning and its clinical effects in condylar reconstruction for such patients using autogenous coronoid process. Sixteen patients with bilateral bony ankylosis of the TMJ from March 2006 to March 2009 were randomly divided into 2 groups and treated by bilateral osteoarthrectomy and condylar reconstruction by free grafting of autogenous coronoid process with and without three-dimensional simulation using Surgicase CMF™ (Materialise, Belgium) software. Clinical examination, radiographs, photographs, and details of the operation and its outcome were used postoperatively to evaluate the clinical effects of the technique. Satisfactory mouth opening was achieved in all cases. There were fewer postoperative malocclusions among patients who had three-dimensional simulation. The combination of computer-assisted three-dimensional surgical planning and simulation and free grafting of autogenous coronoid process is a sound and predictable method for the reconstruction of condyles in patients with bilateral ankylosis of the TMJ as it makes the operation easier and more accurate.
在过去10年里,我们中心每年治疗20多名颞下颌关节(TMJ)双侧关节强直患者。在此,我们描述使用计算机辅助三维手术规划及其在使用自体喙突对这类患者进行髁突重建中的临床效果。2006年3月至2009年3月期间,16例TMJ双侧骨性强直患者被随机分为两组,分别接受双侧关节切除术,并使用Surgicase CMF™(Materialise,比利时)软件,在有或没有三维模拟的情况下,通过自体喙突游离移植进行髁突重建。术后通过临床检查、X线片、照片以及手术及其结果的详细信息来评估该技术的临床效果。所有病例均实现了满意的开口度。进行三维模拟的患者术后咬合不正较少。计算机辅助三维手术规划与模拟以及自体喙突游离移植相结合,是TMJ双侧关节强直患者髁突重建的一种可靠且可预测的方法,因为它使手术更简便、更精确。
