“…The 1-year scores under quiet and under noisy conditions for the entire group of 28 subjects presented in this study were 84 and 64%, respectively. These results are almost the same as were achieved previously in a subgroup of 10 adults (85% in quiet, 60.5% in noise) [Skarzynski et al, 2006] and comparable to those achieved in a subgroup of 9 children (69% in quiet and 62% in noise) [Skarzynski et al, 2007b]. The data support our conclusion that the results of PDCI are highly reproducible.…”

Nineteen adults and 9 children who received a unilateral cochlear implant between 2002 and 2007 were included in the study. All subjects were preoperatively diagnosed with significant residual hearing in low frequencies, termed as ‘partial deafness’, and were implanted according to a 6-step round window surgical technique for partial deafness cochlear implantation. Hearing was preserved to a great extent in the partial deafness cochlear implantation (PDCI) group. After a short period following activation of the cochlear implant, highly significant improvement in the recognition of monosyllabic words was observed. With a developed round window surgical procedure and limited electrode insertion, hearing can be preserved in the majority of patients with partial deafness. PDCI is a feasible means of treating individuals who have good low-frequency hearing but severe to profound hearing loss in the mid to high frequencies.

“…The benefits of preserving acoustic hearing over a 1-year observation period were demonstrated in the first 10 adults [Skarzynski et al, 2006[Skarzynski et al, , 2007a and 9 children [Skarzynski et al, 2007b].…”

“…These people usually achieve limited benefits from conventional amplification with hearing aids, especially in presence of reduced dynamic range [1][2][3][4]. Several studies investigated how to better preserve the low frequency hearing including the surgical technique, the electrode design, and depth of insertion [5].…”

People with residual hearing in the low frequencies and profound hearing loss in the high frequencies often do not benefit from acoustic amplification. Focus on this group of patients led to the development of the combined electric-acoustic stimulation (EAS) systems which can provide users with greater speech perception than can cochlear implant (CI) alone or acoustic hearing alone. EAS users wear a combined speech processor that incorporates a behind-the-ear audio processor that sits with an ear hook on the user's pinna and a hearing aid, which sits in the ear canal. However, with the introduction of single-unit processors, which combine the audio processor, coil, control unit, and battery pack into a single device that sits on the implant site, therefore off the ear, simultaneous electric (CI) and acoustic (hearing aid) stimulation is not currently possible with a combined processor. To achieve EAS with a single-unit processor, a CI user must also wear a hearing aid. This study seeks to determine if experienced users of combined EAS speech processors could also benefit from using a combination of a single-unit speech processor that sits off the ear and an in-the-ear hearing aid.

“…This is in part because its impact on outcomes in patients with partial deafness or residual low frequency is now well established. Various studies and groups have demonstrated the benefits of combining the residual low-frequency hearing with the implant-mediated electric stimulation for speech in noise perception, sound localisation and music perception [von Ilberg et al, 1999;Skarzynski et al, 2007;Dorman and Gifford, 2010;Gifford et al, 2010]. Attention is now directed towards identifying the key factors for hearing preservation and subsequently to optimise these factors in order to achieve the greatest possible preservation of residual hearing in the implanted ear.…”

The Effects of Insertion Speed on Inner Ear Function during Cochlear Implantation: A Comparison Study

2012

Objective: To investigate the insertion speed and its impact on electrode insertion characteristics, hearing preservation and clinical vestibular function in a prospective cohort study with a retrospective control group at a tertiary otology/neurotology centre. Interventions: Hearing-preserving cochlear implantation using systemic and topical steroids in conjunction with a round-window approach, a complete cochlear coverage electrode and two different electrode insertion speeds [60 mm/min (n = 18) vs. 15 mm/min (n = 22)] was performed. Results: The insertion speed had a significant impact on various insertion characteristics as well as hearing preservation and vestibular function. In conclusion, a slow electrode insertion speed appears to facilitate full electrode insertion, reduce the occurrence of insertion resistance as well as promote preservation of residual hearing and vestibular function after cochlear implantation.
