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。
Six adult rhesus macaques were used as experimental animals. Quantitative determination of jaw blood supply by radionuclides was used to compare the blood supply of the inferior alveolar artery with the extra-lateral pterygoid-articular capsule. Found in the condylar condylar cervical and posterior border of the blood supply to the medial pterygoid-joint capsule Fu Li Habitat main position, while in the mandibular angle of blood supply to the lower alveolar artery Habitat main status. Only from the perspective of blood supply, mandibular ramus oblique oblique incision is superior to the vertical incision, and found in the ascending branch there is a regional retrograde blood flow.
