Paediatric cochlear implantation: adverse prognostic factors and trends from a review of 174 cases
Insights
Inner ear malformations and family concern negatively impact paediatric cochlear implantation (PCI) outcomes. Late implantation age also showed a negative association, highlighting key prognostic factors for PCI success.
Area of Science:
- Audiology
- Pediatric Otolaryngology
- Speech-Language Pathology
Background:
- Paediatric cochlear implantation (PCI) is a critical intervention for hearing loss in children.
- Identifying prognostic factors is essential for optimizing PCI outcomes and patient management.
Purpose of the Study:
- To identify and evaluate prognostic factors associated with paediatric cochlear implantation (PCI) outcomes.
- To analyze the influence of various variables on language, vocabulary, and auditory performance post-implantation.
Main Methods:
- Retrospective review of 174 paediatric patient charts.
- Analysis of variables including age at implant, family concern, inner ear malformations, and other comorbidities.
- Multiple regression analysis to determine predictors of language and vocabulary outcomes at 18-24 months post-implant.
Main Results:
- Inner ear malformations and family concern were significantly associated with poorer receptive and expressive language and vocabulary scores.
- A trend suggested that older age at implantation correlated with lower language scores.
Conclusions:
- Inner ear malformations, family involvement, and age at implantation are statistically validated prognostic factors for PCI.
- Further research is needed to clarify the impact of malformation severity and standardize outcome measures for PCI.
- Emphasizing the role of family and refining the study of implantation age in pre-lingually deafened children are crucial for future research.
Objectives:
Identification and evaluation of prognostic factors that are associated with paediatric cochlear implantation (PCI) outcomes was the aim of this study.
Methods:
A retrospective review of 174 charts was performed at the Royal Children's Hospital and the Hear and Say Centre, Brisbane. This examined the possible influence of a number of variables (including age at implant, family, additional disabilities, surgical complications, gender, GJB2 mutations, meningitis, inner ear malformations, and prematurity) on outcome measures: receptive, expressive, and total language, receptive and expressive vocabulary, speech articulation and categories of auditory performance at 18-24 months post-implant. Multiple regression analysis was used to identify variables related to language and vocabulary outcomes.
Results:
The findings suggest that inner ear malformations and family concern are negatively associated with receptive and expressive language and receptive vocabulary scores. There was marginal evidence to suggest that increasing age at implantation was associated with lower receptive and expressive language scores.
Discussion:
Prognostic factors that have been adequately validated statistically include inner ear malformations, the influence of family and late age at implantation. However, this study identified a need to define better the impact of the various degrees of inner ear malformations, to particularly emphasize the role of family as a strong predictor of PCI outcomes, and to confine the study of 'age at implantation' to pre-lingually deafened children.
Conclusion:
Evaluation of prognostic factors is a key element in PCI. This study confirmed several factors that are strongly associated with outcomes. For better research, there is a need for universal standardized outcome measures and development of a standardized framework for recording patient data.
