【摘要】：目的:探讨成人锤砧关节和砧镫关节的正常HRCT表现及临床意义。方法:回顾性分析46例成人的正常锤砧关节和砧镫关节HRCT图像,对其形态进行影像学分类;对可能存在的两侧锤砧关节或砧镫关节形态不对称情况进行统计;对锤砧关节和砧镫关节间隙进行影像学测量,利用统计学软件计算得到一组正常值范围。结果:锤砧关节HRCT表现为3种形态:均匀的弧形(77耳,83.7%)、锯齿样(9耳,9.8%)和喇叭口样(6耳,6.5%);砧镫关节形态为2种:直接连接(31耳,33.7%)和间接连接(61耳,66.3%)。46例受检者中,两侧锤砧关节形态不对称5例(10.9%);砧镫关节形态不对称3例(6.5%)。对横断面上的锤砧关节和镫骨斜位上的砧镫关节间隙的测量结果分别为(0.45±0.10)mm和(0.43±0.12)mm。结论:锤砧关节和砧镫关节的正常HRCT表现可为特殊情况下诊断锤砧关节和砧镫关节脱位提供较为客观的参考依据。
[Abstract]:Objective: to investigate the normal HRCT features and clinical significance of the hammer-anvil joint and stirrup joint in adults. Methods: the HRCT images of 46 adults with normal hammer-anvil joint and incudral joint were analyzed retrospectively. Their morphology was classified by imaging. The asymmetry of the shape of the hammerstock or stirrup joint on both sides was analyzed. A group of normal values were calculated by using statistical software. Results: the HRCT of hammer-anvil joint showed three types: uniform arcuate shape and 77 ears. 83.7% of the ears, 9 ears with serrated teeth, 9 ears with 9 ears, and 6 ears with trumpets. The shape of stirrup joint was divided into two types: direct connection with 31 ears and 33. 7%) and indirect connection with 61 ears of 61 ears. The anvil joints of both sides were dissymmetrical in shape in 5 cases. The results of the measurement of the space between the anvil joint on the cross section and on the oblique position of the stapes were 0.45 卤0.10mm and 0.10mm, respectively. Conclusion: the normal HRCT findings of the anvil joint and the stirrup joint can provide an objective reference for the diagnosis of the dislocation of the anvil joint and the stirrup joint under special circumstances.

【正文快照】： 听骨链损伤是颅脑损伤的常见并发症,但其引起的听力下降在伤后早期往往没有引起临床上的足够重视。这是因为伤后早期所关注的重点多为颅脑损伤或其他较严重的合并伤;并且锤砧关节位于上鼓室,常规的鼓室探查难以发现其病变。此时对听骨链损伤的诊断只能依靠影像学手段。明显的
