“…Vibrotactile or questionable vibrotactile responses were considered as no response. Hearing preservation after cochlear implantation was assessed using the HEARRING group hearing preservation classification (11). As this classification is scaled to the preoperative pure-tone average (PTA), the effect that worse preoperative hearing tends to produce less postoperative hearing loss and better hearing preservation rates is corrected.…”

“…The results of the audiological tests of the steroid-administered group at more than 12 months after CI (17.6 ± 7.0 months) were compared with audiological results of the control group after CI. HP was defined as the difference between preoperative and postoperative hearing thresholds [(250 Hz + 500 Hz + 1,000 Hz + 2,000 Hz)/4] and stratified as by the HP classification system [Skarzynski et al, 2013] (online suppl. table 1; for all online suppl.…”

Dexamethasone Is One of the Factors Minimizing the Inner Ear Damage from Electrode Insertion in Cochlear Implantation

The aim of this study was to investigate the efficacy of preoperative and intraoperative steroid administration for inner ear protection in cochlear implantation (CI). Nineteen subjects who underwent CI were included in the study, and 10 subjects were enrolled as controls (steroid-administered group, n = 19; control group, n = 10). Dexamethasone (dexamethasone sodium phosphate, 5 mg/ml) was systemically administered preoperatively (1 ml) and topically applied during CI (0.5 ml). The extent of hearing preservation (HP) after CI and the change in the bithermal caloric response were evaluated. Hearing level was calculated using mean thresholds [(250 Hz + 500 Hz + 1,000 Hz + 2,000 Hz)/4]. Preoperative hearing thresholds were similar in the steroid-administered and control groups (100.92 ± 12.60 vs. 103.29 ± 14.39 dB, p = 0.650). The mean thresholds significantly increased in both groups after surgery (108.46 ± 14.08 dB, p = 0.006, for the steroid-administered group; 117.50 ± 6.34 dB, p = 0.027, for the control group), and the difference between the groups was also significant (p = 0.027). The postoperative shift in the hearing thresholds at frequencies of 500 and 1,000 Hz was significant in the steroid-administered group and that at the frequencies of 500, 1,000 and 2,000 Hz was significant in the control group. However, the extent of the shift in hearing threshold levels at each frequency was not significantly different between the groups. Preservation of hearing thresholds was compared between the groups, and there were significantly more subjects with complete and partial HP in the steroid-administered group than in the control group (p = 0.008). The preoperative caloric response was maintained after CI in the steroid-administered group. This study suggests that the perioperative use of a steroid could minimize the inner ear damage after CI.

“…Accordingly, in the PDT-EAS group, electrode insertion depth was adjusted from 20 to 25 mm. The degree of hearing preservation was assessed following the hearing preservation classification [Skarzynski et al, 2012[Skarzynski et al, , 2013 ( table 1 ). The hearing loss was then converted to preservation by calculating 100% minus relative change yielding a percent value (S) that is more easily compared among different hearing loss populations: PTA max , derived from the limits of an audiometer at varying test frequencies, is calculated individually according to frequencies from 125 to 8,000 Hz.…”

Hearing disorders become an increasingly important issue that influences quality of life and many other economic factors. Due to the prolongation of human life and the more active lifestyles of people in retirement age, there is an increasing requirement for the available treatment options of hearing loss in the aging population. The aim of this study was to compare the hearing preservation outcomes of adult patients implanted with the Cochlear™ Nucleus® CI422 when divided into two groups by age, younger and older than 65 years of age. The study cohort consisted of 62 patients implanted from January 2011 through December 2013 at our clinic. All patients were assessed and classified according to the hearing preservation classification. Comparing the results between subgroups, we observed that the degree of hearing preservation was greater in younger adults than in older adults. Results of this review may suggest that deeper insertion is to be recommended for an older population of cochlear implant recipients.
