双侧性突发性聋罕见,在日本约占突发性聋的7％,而同时发病者仅占1.7％,作者在七年间观察329例突发性聋患者,发现同时双侧发病者5例。起病诱因多与感冒、咽炎、腮腺肿大等有关。听力曲线多呈全频下降,对称性。预后,在10耳中有7耳明显好转,1耳好转,2耳无变化。既往多认为双侧性预后不良。有人曾报告合并于糖尿病的突聋患者16例,有7例为双侧性,其中同时双侧发病者3例。其他诱因还有血管病变,如双侧椎动脉狭窄、脯梗塞、脑 Bilateral sudden deafness rare, accounting for about 7% of sudden deafness in Japan, while the incidence of only 1.7%, the author observed in 329 cases of sudden deafness in seven years and found that patients with bilateral onset of 5 example. More incentives and cold, pharyngitis, parotid swelling and so on. Hearing curves were mostly full-frequency decline, symmetry. Prognosis, 7 ears significantly improved in 10 ears, 1 ears improved, 2 ears no change. Previously think that bilateral poor prognosis. It was reported in patients with sudden deafness in 16 cases of diabetes, there are seven cases of bilateral, of which the incidence of bilateral at the same time in 3 cases.
