摘要
用6只成年恒河猴作实验动物,采用核素定量测定颌骨血供的方法,就下颌升支后份血供问题将下牙槽动脉与翼外肌—关节囊两供血因素加以对照研究,发现在髁突髁颈区及后缘区血供中翼外肌—关节囊附丽居主要地位,而在下颌角区血供中下牙槽动脉居主要地位。仅从血供角度看,下颌升支斜行切开术优于垂直切开术,并发现在升支后份存在有区域性逆行血流供血现象。
The rhesus monkey was selected as the experimental animal,because its vascular anomusculoskeletal architectures are similar to that of the human.Six adult monkeys wereused.Activity of bone in each region of the posterior region of ramus was measured 120minutes after intravenous injection of ^(99)m Technetium-MDP.After statistic analysis ofthe findings,the authors have evaluated objectively influence upon blood supply of theposterior region of ramus after the lower alveolar artery was ligated and masseter muscle,medial pterygoid and temporal muscles were detached from ramus which was pedicled tothe articular capsule and lateral pterygoid muscle or the ramus was stripped away all ofits soft tissue attachments but the lower alveolar artery.
