RESUMEN
OBJECTIVES: To compare the clinical efficiency of the CR220 intraoperative remote assistant device used by the surgical team with that of the custom sound (CS) system used by an audiologist. METHODS: This was a prospective clinical study in a quaternary care center (King Abdullah Ear Specialist Centre) in Riyadh, Saudi Arabia, between October 2018 and March 2019. We included adult and pediatric patients who underwent cochlear implant (CI) surgeries. For every participant, the intraoperative CI testing was performed via both the aforementioned methods. The time taken to complete the measurements with both approaches, including the time required by the audiologist to reach the operating room (OR) and to complete the test, was recorded. RESULTS: There were no significant differences in the number of responding electrodes between the 2 approaches. For the 25 participants, the time taken for the measurements was 566 minutes with the CS and 173 with the CR220 systems. This significant difference indicates that considerable time can be saved. CONCLUSION: The CR220 enables intraoperative CI electrode tests and auto-NRT measurements. Its ergonomics and ease-of-use help the surgical team conduct the tests without an audiologist in the OR, resulting in the efficient use of clinical resources. Further, the results generated were consistent with those of the CS system.

OBJECTIVES: To determine whether distance from a cochlear implant (CI) center can influences the ages of presentation and intervention for CI, which thus may influence CI outcomes in Saudi Arabia. METHODS: This study comprised a retrospective cross-sectional analysis of 221 patients who presented to the CI committee between March 2016 and March 2018 at King Abdullah Ear Specialist Center, Riyadh, Saudi Arabia. Through phone interviews and patients' files, age at suspicion, audiology testing, diagnosis, hearing aid fitting, and CI discussion were recorded for prelingually deaf children; additionally, demographic information were recorded. Patients were divided into 3 groups based on the distance between their place of residence and the nearest CI center (residing within 200 km, 200-500 km, and greater than 500 km). RESULTS: Patients living within 200 km showed the youngest mean age for all tested checkpoints; however, there were no statistically significant differences among the groups. CONCLUSION: In Saudi Arabia, distance from CI center does not have a significant effect on age of presentation for CI intervention.

OBJECTIVE: To determine if cochlear implants recipients can be safely and effectively fitted with their sound processor one day after their implant surgery. DESIGN: All subjects were implanted with MED-EL Concerto cochlear implant. Subjects' electrode impedance levels, maximum comfortable levels, and threshold levels were measured one day after surgery and compared to measurements obtained one month post implantation using the non-parametric Wilcoxon signed-rank test. STUDY SAMPLE: Twenty-nine participants in the age range of 1 to 42 years (average of 5 years). RESULTS: No adverse events were reported post-operatively. Measures after one day of surgery were significantly less than those measured one month post implantation. CONCLUSION: Early activation of the implant did not impact the healing process of the incision site, suggesting that one-day activation of the implant is feasible for some patients when medically possible. The evolution of the impedance and stimulation levels were consistent with that reported in previous studies, which indicates that early activation did not interfere with the physiological changes taking place after implantation.
