    Author: Leng T, Zhao S.
    Journal: Lin Chuang Er Bi Yan Hou Ke Za Zhi; 2005 Jan; 19(1):9-11. PubMed ID: 15830694.
    Abstract:
    OBJECTIVE: To investigate the effect of stapes surgery for conductive hearing loss with intact tympanic membrane and eustachian tube. METHOD: Stapes surgery data of 95 conductive hearing loss patients, which with intact tympanic membrane and eustachian tube, was retrospective analyzed,and the surgical effect of otosclerosis, middle ear deformities and external canal stenosis was summarized. RESULT: Postoperative (4 weeks after the surgery) pure tone threshold test demonstrated that the effect of Vestibulotomy was better than incus-footplate connection (incus and footplate is connected by a cortical bone ) ( P <0.05). The surgery to the patients with external canal stenosis was better than those with otosclerosis or middle ear deformities ( P <0.05). There was no statistic significance between physiological stapedectomy and Vestibulotomy. The follow-up of 1-3 years showed that the pure tone threshold of 8 out of 14 cases reverted to the preoperative level, while the hearing improvement in the other cases still remained. CONCLUSION: Stapes surgery to the patients with stapes-oval window deformities is of significance compared with those with otosclerosis.
