Abstract

Objective: The primary objective was to report on experiences regarding the safety and efficacy of the Vibrant Soundbridge (VSB) using a floating mass transducer (FMT)-partial/total ossicular replacement prosthesis (PORP/TORP) assembly as a treatment for conductive and mixed hearing losses of mild-to-moderate/severe degree. The secondary objective was to gather information regarding device fitting, as well as to refine surgical procedures., Patients: Five German-speaking adults from 2 European study sites were implanted with a VSB using an FMT-PORP/TORP assembly and evaluated before and after surgery for air-and bone-conduction thresholds and speech recognition performance., Main Outcome Measures: Evaluating the safety and efficacy of the VSB in combination with a PORP or TORP to treat conductive and mixed hearing loss., Results: Residual cochlear hearing was unaffected by implantation with the device. Functional gain (measured as the difference between preoperative unaided and postoperative VSB-aided thresholds) could be calculated in 2 of 5 subjects, demonstrating that the VSB is effective in treating bone-conduction hearing losses of moderate/severe degree. Word recognition tests in quiet and noise showed good improvement in 3 of the cases. One patient experienced several other medical problems, making her audiological outcomes limited. One patient was excluded from the study owing to insufficient benefit and subsequently underwent revision surgery with FMT placement at the round window., Conclusion: The use of the VSB, implanted using the FMT-PORP/TORP assembly, was safe in all and efficacious in 3 of the 5 cases in this study. These are patients who may have few, if any, other options to manage their hearing loss.

Abstract

Objectives: To describe a technique for the intraoperative monitoring of residual hearing during a cochlear implant (CI) procedure and, thus, to identify the time of occurrence and surgical steps leading to hearing loss., Study Design: Prospective audiologic analysis in a patient series., Setting: Tertiary referral center., Subjects: Patients with residual hearing subjected to cochlear implantation., Interventions: During cochlear implantation, cochlear microphonics (CMs) in response to frequency-specific stimuli were recorded in patients with residual hearing. Thresholds were determined before and after opening of the cochlea, with a limited portion of the electrode array inserted, and after full insertion., Results: Monitoring of the hearing state using CMs was quick, reliable, and capable of detecting an intracochlear trauma. In a first series of patients, thresholds were preserved in all patients after opening of the cochlea. Thresholds were preserved in 5 of 6 patients after limited insertion and half of the patients after full insertion of the electrode array. Despite threshold preservation until the end of surgery, the residual hearing was lost in patients with deep insertions 1 week postoperative., Conclusion: Intraoperative monitoring of CM thresholds may be valuable for identifying the exact point of time at which residual hearing is affected in CI patients. Opening of the cochlea itself seems to be unrelated to hearing loss. A significant proportion of patients may have hearing loss caused by secondary effects rather than a direct trauma.

Abstract

Objective: To describe a technique enabling the intraoperative assessment of the mechanical coupling of active middle ear implants in patients with normal or dysfunctional middle ears., Patients: Patients with sensorineural or mixed hearing loss subjected to revision surgery of an active middle ear implant., Intervention: Recording of compound action potentials (CAPs) of the auditory nerve in response to stimulation via an active middle ear implant during revision surgery., Main Outcome Measures: CAP thresholds as a measure of mechanical coupling and system integrity., Conclusion: Determining CAP thresholds may be suitable for identifying a proper mechanical coupling of active middle ear implants in patients with a dysfunctional middle ear, even if the ossicular chain is disrupted.
