All were male (aged 3-18 years,average 13.5 years) and operated on the left side.Malformation was bilateral in 3 patients and unilateral in 1 patient. Surgical techniques were modified to accommodate each patient’s unique conditions and needs.The implant site was approached via the facial recess in 3 patients and through a retro-facial nerve route in 1 patient. The VSB implant was connected to either the stapes (2 cases) or the round window (2 cases).Pure tone and speech audiometry results and daily communication capabilities before and after VSB activation were compared.Results The operations were successful in all patients, with no complications. The patient communication level improved significantly after VSB activation. Average air conduction pure tone threshold or conditioned reflex audiometry threshold improved by 35 dB in the 0.25-4 kHz range,from 69 dB HL before VSB activation to 34 dB HL after.The sentence recognition rate in quiet at 65 dB SPL went up to 86% from 0% without VSB for patients with bilateral deformation and remained at 100% for the patient with unilateral deformity. However, for the latter patient, the rate improved to 20% from 0% without VSB in noise (-8 dB SNR).Conclusion VSB is an excellent solution for improving hearing in patients with congenital deformation of middle and outer ears.Operation can be completed and good results can be achieved even in patients with unique conditions and needs.展开更多
目的比较纯音听阈法与Jahrsdoerfer评分法对先天性中外耳畸形的评估作用。方法将53例(53耳)行外耳道再造+鼓室探查成形手术的先天性中外耳畸形患者分有、无卵圆窗发育两组,对比其术前在0.5-4k Hz各频率平均纯音听阈(或条件反射测听阈值)...目的比较纯音听阈法与Jahrsdoerfer评分法对先天性中外耳畸形的评估作用。方法将53例(53耳)行外耳道再造+鼓室探查成形手术的先天性中外耳畸形患者分有、无卵圆窗发育两组,对比其术前在0.5-4k Hz各频率平均纯音听阈(或条件反射测听阈值)、Jahrsdoerfer评分及相应平均纯音听阈情况,比较两种方法的差异。结果两组术前平均气导听阈卵圆窗发育组为64.7 d B,无发育组为73.1 d B(P<0.05),且在1k Hz、2k Hz、4k Hz两组有差异(P<0.05)。Jahrsdoerfer评分卵圆窗未发育组7分以下(含)占83.3%,而发育组为35.7%,但评分高低与平均听阈值间无程度梯度关系。结论:纯音听阈法和Jahrsdoerfer评分法均能反映先天性中外耳畸形的畸形程度,但纯音听阈法更简单、直接。Jahrsdoerfer评分高低与纯音听阈水平不能互相进行评估。展开更多
