Aetiological investigation of sensorineural hearing loss in children

Area of Science:

• Pediatrics
• Otolaryngology
• Audiology

Background:

• Sensorineural hearing impairment (SНІ) in children requires thorough etiological investigation.
• Current diagnostic practices by ENT consultants and community pediatricians in audiology vary.
• Guidelines from professional bodies like BAAP and BACDA exist to standardize investigations.

Purpose of the Study:

• To survey the current etiological investigations for children with severe/profound bilateral sensorineural hearing impairment.
• To identify areas for improvement in the diagnostic workup of pediatric hearing loss.
• To assess adherence to recommended investigation protocols.

Main Methods:

• A survey methodology was employed to gather data on investigations performed.
• Data was collected from ENT consultants and community pediatricians involved in pediatric audiology.
• Analysis focused on the types and frequency of etiological investigations utilized.

Main Results:

• The survey revealed a need for greater routine utilization of specific investigations.
• Electrocardiogram (ECG), urine analysis, and ophthalmological assessments were identified as underused.
• A more selective approach to other investigations, aligning with BAAP/BACDA recommendations, is suggested.

Conclusions:

• Current etiological investigations for pediatric sensorineural hearing impairment may not be fully optimized.
• Standardizing and increasing the use of key investigations like ECG, urinalysis, and ophthalmological exams is warranted.
• Adoption of a more selective, guideline-based approach to audiological investigations can improve diagnostic yield.
