Audiological outcomes of robot‑assisted cochlear implant surgery

Tijdschriftbijdrage - Tijdschriftartikel

Purpose The main objective of this study is to evaluate the short-term and long-term audiological outcomes in patients who
underwent cochlear implantation with a robot-assisted system to enable access to the cochlea, and to compare outcomes
with a matched control group of patients who underwent cochlear implantation with conventional access to the cochlea.
Methods In total, 23 patients were implanted by robot-assisted cochlear implant surgery (RACIS). To evaluate the effectiveness
of robotic surgery in terms of audiological outcomes, a statistically balanced control group of conventionally implanted
patients was created. Minimal outcome measures (MOM), consisting of pure-tone audiometry, speech understanding in
quiet and speech understanding in noise were performed pre-operatively and at 3 months, 6 months, 12 months and 2 years
post-activation of the audioprocessor.
Results There was no statistically significant difference in pure-tone audiometry, speech perception in quiet and speech perception
in noise between robotically implanted and conventionally implanted patients pre-operatively, 3 months, 6 months,
12 months and 2 years post-activation. A significant improvement in pure-tone hearing thresholds, speech understanding
in quiet and speech understanding in noise with the cochlear implant has been quantified as of the first measurements at
3 months and this significant improvement remained stable over a time period of 2 years for HEARO implanted patients.
Conclusion Clinical outcomes in robot-assisted cochlear implant surgery are comparable to conventional cochlear
implantation.
