本文比较耳硬化症患耳与正常耳的声顺值,观察鼓室压测量对耳硬化症的诊断价值。方法和结果:34例为曾作过一侧手术已确诊耳硬化症者,未手术侧耳需符合下列条件:①传音性聋,0.5、1、2 KH z骨气导差10dB(H L),②声反射消失。③鼓膜正常。④未作过手术,34例对照组的条件为:①无传音性聋。②声反射存在;0.5、1、2 K Hz气骨差<10dB。③鼓膜正常。两组用同法行纯音测听及鼓室测量法。每组男9例,女25例,年龄21～78岁,平均47岁。气骨导差18～54dB,平均34dB。平均声顺值耳硬化症耳为0.46±0.33ml,正常耳为0.56±0.37ml,二者声顺值的范围有较多重叠,90%耳硬化症耳的声顺值<1.0ml,但88%(30/34)的正常耳亦如
This article compares the auditory compliance of otosympathetic and normal ears, and evaluates the diagnostic value of tympanometry for otosclerosis. Methods and Results: Thirty-four cases of otosclerosis who had undergone one-sided surgery had to meet the following criteria: ① acoustic deafness, 0.5, 1, 2 KH z osteoporosis 10 dB (HL), ② Acoustic reflections disappear. ③ normal tympanic membrane. ④ did not make surgery, 34 cases of control group conditions: ① no acoustic deafness. ② acoustic reflex exists; 0.5,1,2 K Hz difference between the gas bone <10dB. ③ normal tympanic membrane. Two groups with the same law pure tone audiometry and tympanometry. Each group of 9 males and 25 females, aged 21 to 78 years, mean 47 years. Difference in airbone 18 ~ 54dB, an average of 34dB. The average acoustic compliance of otosclerosis ear was 0.46 ± 0.33ml, normal ear was 0.56 ± 0.37ml, there was more overlapping between the two, and 90% of the ears with otoconjunctival compliance value <1.0ml, but 88 % (30/34) of the normal ear is also as
