目的:探讨一种测量下颌偏斜程度新方法(眶下裂法)的临床应用价值。方法:选择20例骨性下颌偏斜患者,由6名不同年资医师分别独立运用棘孔法和眶下裂法对下颌偏斜程度进行2次测量(单盲法),对2次测量结果进行配对t检验。结果:①6名医师2次测量结果自身比较,棘孔法除1名医师重复测量结果差异无统计学意义外(P>0.05),其余5名医师重复测量结果差异均存在统计学意义(P<0.05)。眶下裂法6名医师重复测量结果差异均无统计学意义(P>0.05)。②相同年资及不同年资医师间第1次测量值比较,结果差异均无统计学意义(P>0.05),差异与测量者的经验无直接相关。结论:与棘孔法相比,眶下裂法具有测量点明确、操作方便、测量结果误差小、重复性好等优点。
Objective: To explore a new method of measuring the degree of mandibular deviation (infraorbital fissure) clinical value. Methods: Twenty patients with skeletal mandibular deviation were selected, and 6 physicians of different ages independently used the method of spinous hole and infraorbital rupture to measure the degree of mandibular deviation twice (single-blind method). The results of two measurements Paired t test. Results: ①There was no significant difference between the two physicians in two measurements (P> 0.05), but there was no significant difference between the two doctors (P> 0.05). The differences among the other five doctors were statistically significant (P < 0.05). There was no significant difference in repeat measurement results between the six physicians of infraorbital fissure (P> 0.05). ② There was no significant difference in the results of the first measurement among the same years of qualifications and physicians with different years (P> 0.05). There was no direct correlation between the differences and the experience of the surveyors. Conclusion: Comparing with acupoint-hole method, infraorbital fissure method has the advantages of definite measurement point, convenient operation, small measurement error and good repeatability.
