目的：测定颞下颌关节疾病患者的关节内压。方法：对１６ 例２０ 侧关节在局部麻醉下测定了开口位及闭口位关节上腔内压值。结果：在闭口位，关节上腔内压平均为：（２．４１６±１．９７２） ｋ Ｐａ（ｎ＝ １８）；开口位为：（２．８３７±２．５４３） ｋ Ｐａ（ｎ＝１８）。与正常人相比颞下颌关节疾病患者关节内压升高（ Ｐ＜ ０．０５）。结论：颞下颌关节上腔内压测定方法简便易行，可用于反映颞下颌关节的功能状态。
Objective: To determine the intra-articular pressure in patients with temporomandibular joint disease. Methods: Twenty-sixteen patients with 20 joints underwent local anesthesia to measure the intra-articular pressure of the open mouth and closed mouth joint. Results: In the closed position, the average intra-articular pressure was (2.416 ± 1.972) kPa (n = 18) and the open position was (2.837 ± 2.543) kPa ). Compared with normal people, patients with temporomandibular joint disease had higher intra-articular pressure (P <0.05). Conclusion: The method of determination of temporomandibular joint pressure in the superior lumen is simple and convenient and can be used to reflect the functional status of temporomandibular joint.
