与脉搏一致的搏动性耳鸣是一个重要信号。作者观察了42例以此种耳鸣为主要症状的患者。该种耳鸣最常见于血管球性肿瘤(化学感受体肿瘤)。在迷路两窗生长血管性肿瘤组织伴前毛细管的动静脉吻合,为该种耳鸣的原因。但此种耳鸣亦见于其他疾病。42例中有2例颈静脉球高位;若见肿瘤搏动,也可以是移位之颈内动脉或其假性动脉瘤。故于此类病例行鼓膜穿刺可导致危及生命的出血。鼓室胆固醇性肉芽肿2例,有新鲜肉芽和血管;在迷路窗附近形成并传出耳鸣,术后耳鸣消失。鼻咽癌2例(放疗后1例),均有渗出性中耳炎,耳鸣可能因肿瘤处血管扩张或放疗后疤痕性改变压迫血管所致:耳鸣加剧是因鼓室渗液积聚所致之自听增强。耳硬化症伴耳鸣者3例,但经详查考虑1例与脑血管动静脉瘘、另
Pulsatile pulsatile tinnitus is an important signal. The authors observed 42 cases of tinnitus as the main symptoms of patients. The tinnitus is most commonly found in glomus tumors (chemosensory tumors). Lost in two windows grow vascular tumor tissue with arteriovenous anastomosis before the capillaries for the reasons for the kind of tinnitus. However, this tinnitus is also found in other diseases. In 42 cases there were 2 cases of jugular bulb high; if the tumor beats, it can also be displaced internal carotid artery or its pseudoaneurysm. Therefore, tympanic membrane puncture in such cases can lead to life-threatening bleeding. Tympanic cholesterol granuloma in 2 cases, fresh granulation and blood vessels; formed in the lost window and the outgoing tinnitus, tinnitus disappeared. Nasopharyngeal carcinoma in 2 cases (1 case after radiotherapy), have exudative otitis media, tinnitus may be due to tumor vasodilation or scarring after radiotherapy oppression of the blood vessels caused by: tinnitus increased due to accumulation of tympanic exudate caused by self-listening Enhanced. Ear sclerosis with tinnitus in 3 cases, but after careful consideration of 1 case with cerebral arteriovenous fistula, the other
