The conductive hearing of 18 patients with juvenile chronic arthritis was studied. Tympanometry was therefore undertaken for the assessment of functional state of the tympanic membrane, the ossicular chain with its ligaments and muscles, and the air cushion of the tympanic cavity. Acoustic reflex was present in all patients but an abnormal tympanometric pattern (type As) was found bilaterally or unilaterally in 10 (mostly severe cases) patients. These findings indicate that juvenile chronic arthritis changes middle ear function, probably as a result of inflammation of the synovial ossicular joints, which is followed by stiffness of the tympanic membrane and ossicular chain.
对18例青少年慢性关节炎患者的传导性听力进行了研究。因此进行了鼓室导抗图测量,以评估鼓膜、带有韧带和肌肉的听骨链以及鼓室气腔的功能状态。所有患者均存在听觉反射,但10例(大多为重症)患者双侧或单侧发现鼓室导抗图异常(As型)。这些发现表明,青少年慢性关节炎会改变中耳功能,可能是滑膜听骨关节炎症的结果,继而导致鼓膜和听骨链僵硬。
