Abstract

We investigated the degree of regeneration of the mandibular condyle after unilateral condylectomy and myotomy of the masseter in growing lambs. Four 10-week-old lambs had unilateral condylectomy and myotomy of the superficial layer of the masseter on the right side, and were killed 3 months later. The joints were examined radiologically and histologically. All joints showed poor regeneration of the condylar head. In the medial plane there was partial condylar and articular cartilage reformation, but in the lateral plane there was neither condylar nor cartilaginous reformation. The articular cartilage of the temporal bone was thicker in the medial plane and the disc was thicker in the central plane, than in unoperated joints. We conclude that unilateral condylectomy and myotomy of the masseter in the growing period results in poor regeneration of the condyle.

摘要

我们研究了生长期羔羊单侧髁突切除术及咬肌肌切开术后下颌髁突的再生程度。4只10周龄的羔羊接受了右侧单侧髁突切除术及咬肌浅层肌切开术,并于3个月后处死。对关节进行了放射学和组织学检查。所有关节的髁突头部再生均较差。在内侧平面有部分髁突和关节软骨重塑,但在外侧平面既没有髁突也没有软骨重塑。与未手术的关节相比,颞骨关节软骨在内侧平面更厚,关节盘在中央平面更厚。我们得出结论,生长期单侧髁突切除术及咬肌肌切开术会导致髁突再生不良。
