下颌骨骨折后颞下颌功能紊乱的临床研究

Temporomandibular joint function disturbance after mandibular fracture

目的 :探讨下颌骨骨折后颞下颌功能紊乱的状况。方法 :按照改良Helkimo指数对 3 6例下颌骨骨折患者和 3 2例正常人的颞下颌功能进行比较分析研究。结果 :骨折组和正常组在主诉症状指数 (Ai)、临床症状指数 (Di)的分布上有显著性差异 (P <0 .0 0 1) ,咬合指数 (Oi) 2组之间无显著性差异。结论

Objective: To study temporomandibular joint function after mandibular fracture. Methods: According to the methods of Helkimo, the questionnaire and clinical examination were administered in 36 cases with mandibular fracture and 32 health controls. Results:There were statistically significant difference between the fracture group and control group in anamnestic dysfunction and clinical dysfunction index(P<0.01).The occlusion idexes in the two groups were not statistically different(P>0.05).Conclusion: People with mandibular fracture have more symptoms and sign of temporomandibular dysfunction in the time ranged.
