Since then, the number of users has grown. This larger cohort facilitates a more rigorous analysis of the hearing outcomes that have been achieved by the Malawi cochlear implant (CI) program.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Nineteen children with postlingual severe\u2010to\u2010profound deafness underwent unilateral cochlear implantation between 2014 and 2022. Pure\u2010tone audiometric (PTA) thresholds were obtained for both ears preoperatively, and aided thresholds were determined for the implanted ear postoperatively. To assess hearing outcomes, a battery of open\u2010 and closed\u2010set speech environmental sound perception tests were administered postoperatively. Observations related to the educational status of each participant were also documented.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Cochlear implantation reduced the mean PTA4 threshold from 110.8 (range 96.3\u2010120\u2009dB hearing loss [HL]) to 37.8\u2009dB HL (31.3\u201042.5\u2009dB HL) in the implanted ear, improvements which were clinically meaningful and statistically significant (Wilcoxon signed\u2010rank test: <jats:italic>z<\/jats:italic>\u2009=\u2009\u22123.184; <jats:italic>P<\/jats:italic>\u2009=\u2009.001).
