AI Article Synopsis
- The cochlear implant program in Sydney has implanted 290 adults, utilizing the promontory stimulation test (PST) to evaluate candidates for surgery.
- Analysis of 150 patients showed that 89% who perceived sound during PST had significantly better speech comprehension scores (81%) a year post-implant compared to those with no preoperative stimulability (42%).
- The PST is deemed predictive of improved speech outcomes post-implant and offers patients an initial experience of hearing through electrical stimulation.
Article Abstract
To date, 290 adults have been implanted in the cochlear implant programme in Sydney (Australia), where the promontory stimulation test (PST) is routinely used to assess implant candidacy. There has been much controversy over the exact role and value of this test. Pre- and postoperative speech comprehension tests of 150 implantees were analysed, and scores were compared with preoperative PST performances. Eighty-nine per cent of the patients perceived sound when the promontory was stimulated electrically. This group of implantees scored 81% on CID speech tests at 12 months postoperatively, compared to the minority who lacked preoperative promontory stimulability, who scored 42%. The PST is therefore predictive of greater speech benefits after implantation. It also provides an important psychophysical experience of hearing electrical sound.

The otic capsule and surrounding temporal bone exhibit complex 3D motion influenced by frequency and location of the bone conduction stimulus. The resultant correlation with the intracochlear pressure is not sufficiently understood, thus is the focus of this study, both experimentally and numerically. Experiments were conducted on six temporal bones from three cadaver heads, with BC hearing aid stimulation applied at the mastoid and classical BAHA locations across 0.

: Before a cochlear implant is considered, patients undergo various audiological tests to assess their suitability. One key test measures the auditory brainstem response (ABR) to acoustic stimuli. However, in some cases, even with maximum sound stimulation, no response is detected.

A comprehensive understanding of the effects of bone conduction (BC) input force is essential for elucidating BC hearing mechanisms. However, this area remains underexplored due to the inherent difficulties in controlling input forces when BC transducers are anchored to the bone. In this study, the effects of both unilateral and bilateral BC input forces were investigated using a three-dimensional finite element (FE) model of the human head, which allows precise manipulation of input forces.

Bone conduction implants enable patients to hear via vibrations transmitted to the skull. The main constraint of current bone conduction implants is their maximum output force level. Stimulating closer to the cochlea is hypothesized to increase efficiency and improve force transfer, addressing this limitation.

The use of cochlear implants (CIs) is on the rise for patients with vestibular schwannoma (VS). Besides CI following tumor resection, new scenarios such as implantation in observed and/or irradiated tumors are becoming increasingly common. A significant emerging trend is the need of intraoperative evaluation of the functionality of the cochlear nerve in order to decide if a CI would be placed.
