The purpose of the study was to test the hypothesis that sparing the posterior superior synovial recess during the resection of temporomandibular joint condyle and disk would maintain a critical mass of synovium necessary to predictably achieve a successful allograft joint reconstruction.
A group of 15 adult goats underwent unilateral resection of their temporomandibular condyle and meniscus. The fossa and posterior superior synovial recess were left intact. They were immediately reconstructed with cryogenically preserved allograft mandibular condyles and temporomandibular joint disk harvested from 15 adult donor goats. The animals were evaluated clinically and radiographically at 6 and 12 months and histologically at 12 months.
Of the 15 animals, 13 met all the criteria to be declared a success and retained the posterior superior synovial recess.
Immediate joint reconstruction using cryogenically preserved mandibular condyles and temporomandibular joint disk can have a high rate of success if the native posterior superior synovial recess remains intact.
本研究的目的是检验以下假设,即在颞下颌关节髁突和盘状软骨切除术中保留后上滑膜隐窝,将维持足够数量的滑膜组织,从而可预测地实现同种异体关节重建的成功。
15只成年山羊接受了单侧颞下颌髁突和半月板切除术。关节窝和后上滑膜隐窝保持完整。然后立即用从15只成年供体山羊获取的低温保存的同种异体下颌髁突和颞下颌关节盘进行重建。在6个月和12个月时对动物进行临床和影像学评估,并在12个月时进行组织学评估。
15只动物中,13只符合所有成功标准并保留了后上滑膜隐窝。
如果天然的后上滑膜隐窝保持完整,使用低温保存的下颌髁突和颞下颌关节盘进行即刻关节重建可获得较高的成功率。
