Abstract：Objective To evaluate the short-term hearing and speech rehabilitation of unilateral Ultra cochlear im-plantation(CI)and its safety and efficacy in the real world.Methods Patients with bilateral severe to profound sensori-neural hearing loss(n=78)underwent unilateral CI surgery and completed preoperative baseline assessment,evaluation of hearing improvement,speech development and auditory rehabilitation,as well as adverse events during and after the surgery.Follow-ups were scheduled on the day of switch-on and completed at 1 month±7 days,3 months±14 days and 6 months±30 days after activation respectively.Hearing and speech performance before and after the surgery were ana-lyzed using the SPSS 22.0 software.Results Aided hearing thresholds gradually improved along with rehabilitation af-ter activation,and significantly better than unaided preoperative thresholds(x2=1341.97,P＜0.05 for those＜3 years;x2=912.81,P＜0.05 for those 3 to 5 years;and x2=1495.36,P＜0.05 for those 6 years and older,respectively).Speech recog-nition scores also improved along with rehabilitation,especially as compared to preoperative results(x2=239.08,P＜0.05 with monosyllable words and x2=153.66,P＜0.05 with disyllable words for those 3 to 5 years;x2=281.31,P＜0.05 with monosyllable words,x2=152.44,P＜0.05 with disyllable words and x2=197.06,P＜0.05 with sentences for those 6 years and older).No adverse events resulting in withdrawal from the study.Conclusion Patients with bilateral severe to pro-found sensorineural hearing loss can achieve significant speech and hearing performance improvement even within rela-tively short time of unilateral CI use.The real world data from this study provides reliable evidence supporting clinical application of Ultra CI.
