However, in adults 65 years and older, cochlear implantation for the treatment of SSD and AHL has been difficulty to study given the restrictions in insurance coverage for cochlear implants (CI) due to current Medicare guidelines.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective:<\/jats:title>\n                    <jats:p>This study aimed to evaluate outcomes in patients 65 years old and older who underwent cochlear implantation for SSD and AHL to provide data supporting a change in CI candidacy indications for Medicare beneficiaries.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A cohort of CI recipients over the age of 65 years with either SSD (4-frequency pure tone average [4fPTA] \u226590 dB in the implanted ear and \u226430 dB in the better hearing ear) or AHL (interaural difference in 4fPTA \u226515 dB HL, better hearing ear 4fPTA &gt;30 dB HL and \u226470 dB HL) was identified from a single tertiary-level CI center.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Forty CI recipients \u226565 years (9 SSD; 31 AHL) were identified. There were significant improvements (percentage point change, \u2206%) demonstrated with CI use on consonant-nucleus-consonant (CNC) scores from baseline to 3 timepoints in both SSD (3 m, +38 \u2206%; 6 m, +40 \u0394%; 12 m, +47 \u0394%) and AHL subjects (3 m, 40 \u0394%; 6 m, +41 \u0394%; 12 m, +42 \u0394%). Significant improvements were also seen on AzBio sentences in quiet in both SSD (3 m, +67 \u0394%; 6 m, +45 \u0394%; 12 m, +68 \u0394%) and AHL subjects (3 m, +44 \u0394%; 6 m, +57 \u0394%; 12 m, +54 \u0394%). The status of the contralateral ear accounted for little variance in CNC improvement at 6 or 12 months. Moderate positive associations between device usage and CNC word and AzBio sentence testing were observed at 6 months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
