초록
Stapedial fixation result in conductive hearing loss, and the disrupted sound conduction mechanism could be re- stored with stapes surgery. Conventional stapes surgery cannot be performed in patients with disrupted ossicular chain, especially absence of incus and malleus. In this study, we reported two cases of stapedectomy with ossic- uloplasty in patients with stapedial fixation and disrupted ossicular chain. Stapedectomy was performed in two patients and the oval window was covered with perichondrium or temporalis fascia. Total ossicular replacement prosthesis was inserted between tympanic membrane and oval window. All of patients showed improvement of hearing and subjective satisfaction for outcome. The postoperative air-bone gap was 8.3 and 26.7 dB. Postoper- atively, no complication such as sensorineural hearing loss or dizziness was reported. Therefore, stapedectomy with ossiculoplasty is safe and effective treatment option for patients with conductive hearing loss due to stapedi- al fixation and disruption of ossicular chain
Abstract
Stapedial fixation result in conductive hearing loss, and the disrupted sound conduction mechanism could be re- stored with stapes surgery. Conventional stapes surgery cannot be performed in patients with disrupted ossicular chain, especially absence of incus and malleus. In this study, we reported two cases of stapedectomy with ossic- uloplasty in patients with stapedial fixation and disrupted ossicular chain. Stapedectomy was performed in two patients and the oval window was covered with perichondrium or temporalis fascia. Total ossicular replacement prosthesis was inserted between tympanic membrane and oval window. All of patients showed improvement of hearing and subjective satisfaction for outcome. The postoperative air-bone gap was 8.3 and 26.7 dB. Postoper- atively, no complication such as sensorineural hearing loss or dizziness was reported. Therefore, stapedectomy with ossiculoplasty is safe and effective treatment option for patients with conductive hearing loss due to stapedi- al fixation and disruption of ossicular chain
