颞下颌关节重建术后可能形成异位骨和纤维化,增高了颞下颌关节强直的发生率。有学者将自体腹部或腹股沟的脂肪瓣游离移植到颞下颌关节,能够在一定程度上改善关节动度,但脂肪瓣成活率、脂肪自体吸收量以及取瓣处的术后并发症等限制了其应用。颊脂垫位于颞下颌关节周围,通过耳前切口可轻松探及。在不同重量和脂肪分布的人群中,大小基本一致。颊脂垫的血供丰富且存在广泛的吻合,因此可以考虑采用带蒂颊脂垫来代替脂肪瓣治疗颞下颌关节强直。 Temporomandibular joint reconstruction may form heterogenous bone and fibrosis, increasing the incidence of temporomandibular joint ankylosis. Some scholars have autologous abdominal or groin fat flap free transplantation to the temporomandibular joint, to a certain extent, to improve joint mobility, but the survival rate of fat flap, the amount of fat absorption and flap at the postoperative complications and other restrictions application. Buccal fat pad is located around the temporomandibular joint, through the anterior incision can easily explore. In different weight and fat distribution of the population, the size of the same. Buccal fat pad blood supply and there is a wide range of anastomosis, it can be considered to use pedicled buccal fat pad instead of fat flap for treatment of temporomandibular joint ankylosis.
