Pediatric cochlear implantation: Early surgical intervention and parental quality of life.

OBJECTIVES: Pediatric cochlear implantation (CI) provides sound perception to children with significant sensorineural hearing loss and, despite its challenging process, early implantation can enhance children's speech/language outcomes and potentially improve parental quality of life (PQoL). This study aims to examine parental perspectives on quality of life and parenting children with CI. METHODS: This study combined retrospective chart review and parent reported outcomes. Data were abstracted from medical charts of 85 children who underwent CI between 2016 and 2022 at a tertiary pediatric hospital. Parents were administered the Acceptance and Action Questionnaire (AAQ-MCHL), an 8-item self-report assessment of quality of life for parents of children with CI. Multivariate linear regression analyses examined clinical factors associated with PQoL scores. RESULTS: Parents whose children were implanted at less than two years of age reported significantly higher PQoL, indicated by lower AAQ scores, with a mean AAQ-MCHL of 7.6 + 5.7. In contrast, implantation at age >2 years yielded a mean AAQ-MCHL of 16.2 + 9.6. Parents interviewed within one year post-surgery reported lower PQoL, with a mean AAQ-MCHL of 12.3 + 8.8 compared to those interviewed after one year, with 20.5 + 10.4. CONCLUSION: Early identification of profound hearing loss in children, coupled with early surgical CI, may be associated with higher parental quality of life. The beneficial outcomes appear to be potentiated over time. Further research is essential to fully comprehend the impact of CI on the quality of life of children and their parents.

Round window anatomy predicts ease of cochlear implantation in children.

OBJECTIVES: We aim to evaluate the utility of the Round Window Angle (RWA) as a predictor of difficulty and operative time in cochlear implantation. METHODS: A retrospective study of pediatric patients that underwent cochlear implantation and CT temporal bone imaging from January 2008 to November 2019. Correlation, univariate, and multivariate analysis were conducted. RESULTS: 347 implantations met inclusion criteria. We found a difference in RWA for difficult (median: 101°, n = 5) and non-difficult (median: 74, n = 317) implantations (p < 0.0001). There was also a difference in RWA in patients with round windows visualized intra-operatively (p < 0.0197). When controlling for age and intraoperative round window visualization, logistic regression showed RWA was significantly associated with difficult insertion (OR: 1.687; p = 0.0246). Further, there was positive correlation between RWA and operative time (r = 0.1779, p = 0.0013) with patients with acute RWAs having shorter operative times (mean 115.7 ± 32.1 min) than those with obtuse RWA (mean 183.5 ± 97.0 min) (p = 0.0035). When accounting for surgeon and patient age, multivariate linear regression showed round window visualization (ß = 3.456, p = 0.0006) and obtuse RWA (ß = 6.172, p < 0.0001) was associated with an increase in operative time. CONCLUSION: Further research is needed to identify difficult cochlear implantations to increase the success and reduce risks associated with the surgery. Our study reports the possibility that an obtuse RWA both significantly increases difficulty and time of operation due to decreased round window visualization.
