Possibilities of triphasic stimulation in patients with cochlear implants

The rationale for the use of three-phase stimulation for programming the processor of the cochlear implantation system (CI) in patients with deafness is presented. To study the possibilities of using a new type of stimulation, we selected patients with deafness after cochlear implantation, in whom signs of facial nerve stimulation (FNS) were established in the postoperative period. All subjects were previously installed in the CI processor with individual listening maps based on traditional biphasic stimulation. The use of three-phase stimulation to prevent SOS phenomena is caused by the geometry of the electric current pulse, which allows to reduce the penetrating power of the charge in the tissues and eliminate the effect on the facial nerve, without resorting to reducing the levels of stimulation necessary to create a dynamic range of sound perception. Comparative data of the parameters and the results of audiological testing in 21 patients with symptoms of SLE with traditional (two-phase) and three-phase electrical impulses in the stimulation algorithm of the CI system are presented. The positive effect of three-phase stimulation has been established. The results of the study show a significant increase in sound perception indicators when switching to a three-phase stimulation algorithm.

Removal Technique

This prospective study was undertaken to evaluate the safety and patient acceptance of minimal hair removal during cochlear implantation. Forty-six consecutive patients (17 adults, 29 children; age range 13 months to 84 years) received cochlear implantation with a minimal hair removal technique. A questionnaire was used to evaluate acceptance and value of this technique among the first 15 patients and parents. Postoperative examinations were completed 1 and 4 weeks after implantation. Patients were monitored for complications, which included 3 cases of transient seroma, 2 cases of transient dysequilibrium, 2 individual electrode failures, and 1 facial nerve stimulation. Importantly, no wound infections were documented. Use of a small shave technique did not increase surgical risk. This technique has proved to be cosmetically and psychologically more desirable for the patients and their families than complete hair removal in the operative field.

Facial Nerve Stimulation

Generally, cochlear implants (CIs) are effective in helping patients improve their hearing performance; however, some patients have poor hearing performance owing to facial nerve stimulation (FNS), which is often associated with cochlear anomalies. We report a case with a normal cochlea and severe and persistent FNS owing to cochlear–facial dehiscence (CFD) that affected the CI outcomes. Preoperatively, a careful review of the computed tomography images before CI surgery is necessary not only for patients with otosclerosis and inner ear malformations but also for patients with normal cochlear structures because facial nerve anomalies could be present.
