One case had only skin contaminant growth on culture following multiple oral and parental antibiotic regimens. Surgical excision of diseased cartilage as a result of idiopathic chronic chondritis is an effective treatment in those cases refractory to antibiotics and incision and drainage, and should be considered in the treatment algorithm for similar patients, potentially offering definitive cure.

Compare speech perception performance growth and benchmark score achievement among adult cochlear implant (CI) recipients with single-sided deafness (SSD) versus bilateral moderate to profound hearing loss. Retrospective matched cohort analysis. Tertiary referral center. Adults with SSD or bilateral moderate to profound hearing sensorineural hearing loss who underwent cochlear implantation from 2014 to 2019. Cochlear implantation. Time-to-benchmark speech perception score (CNC, AzBio in quiet) and speech performance within first postoperative year. Thirty-three SSD patients were matched to 66 bilateral hearing loss patients (referent cohort) for duration of deafness and preoperative ipsilateral CNC scores. Although SSD patients were more likely to achieve benchmark CNC scores more quickly compared with matched referents, this difference did not reach statistical significance (HR 1.72; 95% CI 0.78-3.82; p = 0.18). AzBio scores showed similar trends (HR 1.40; 95% CI 0.66-2.98; p = 0.38). At last follow-up, the SSD cohort had lower CNC (median 54% vs. 62%; p = 0.019) and AzBio scores (median 72% vs. 84%; p = 0.029) compared to t
