Vertical asymmetry of the mandibular ramus and condylar heights was measured with a new method from dental panoramic radiographs. The study groups consisted of 45 psoriatic arthritis (PA) and 45 control (CO) matched pairs. Vertical asymmetry was calculated with the formula (R - L)/(R + L) x 100. Females showed no statistical significant difference in vertical asymmetry between the PA and CO pairs. In males however, vertical asymmetry showed a statistically significant difference between the PA and CO groups among those aged 35-55 years (P = 0.008). This group included four men with arthritis mutilans, a severe form of psoriatic arthritis.
采用一种新方法从牙科全景X线片中测量下颌升支和髁突高度的垂直不对称性。研究组由45对银屑病关节炎（PA）患者和45对匹配的对照组（CO）组成。垂直不对称性通过公式（R - L）/（R + L）×100计算得出。女性患者中，PA组和CO组在垂直不对称性方面无统计学显著差异。然而，在男性患者中，年龄在35 - 55岁之间的PA组和CO组在垂直不对称性上存在统计学显著差异（P = 0.008）。该组包括4例毁形性关节炎患者，这是银屑病关节炎的一种严重形式。
