目的：探讨创伤性颞下颌关节强直后儿童颞颌关节血流的变化。材料与方法：应用放射性同位素三相骨扫描方法检查７名创伤性颞下颌关节强直患儿，观察其颞颌关节区血流变化。结果：强直侧颞颌关节区三相骨扫描血流相曲线明显低于非强直侧，强直侧颞下颌关节区延迟相和血池相的放射计数比值比健侧大。结论：创伤性颞颌关节强直可使颞颌关节区血流灌注受到明显影响。
Objective: To investigate the changes of temporomandibular joint blood flow in children with traumatic temporomandibular joint ankylosis. MATERIALS AND METHODS: Seven traumatic temporomandibular joint ankylosis children were examined with radioisotope three-phase bone scintigraphy. The changes of blood flow in the temporomandibular joint were observed. Results: The blood flow curve of the three-phase bone scan in the anastomotic temporomandibular joint was significantly lower than that in the non-ankylosis, and the ratio of the radioactivity count in the delayed phase and the blood pool in the anastomotic temporomandibular joint was larger than that in the contralateral. CONCLUSION: Traumatic temporomandibular joint ankylosis can significantly affect blood flow perfusion in temporomandibular joint.
