Audiological Evaluation of Children below 14 Years Undergoing Tympanoplasty in a Tertiary Teaching Hospital
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 3
Abstract
Introduction: Chronic suppurative otitis media (CSOM) is at a higher incidence in the pediatric population when compared to adults. CSOM results in conductive deafness resulting in difficulty in learning speech skills. Surgical procedures to correct the hearing loss are regarded both by surgeons and parents to give poor results. Selection of children with CSOM developing speech problem and appropriate tympanoplasty in skilled hands will result in post-operative auditory gain. Aims: To study the audiological results in children following tympanoplasty procedures in a tertiary teaching hospital. Materials and Methods: A total of 85 children aged 9-14 years underwent tympanoplasty procedure between October 2015 and April 2017 was included in the study. Post-operative audiological evaluation, perforation closure, factors playing a role in the success rate were recorded and analyzed. Results: Closure of perforation was successful in 92.94% of the children. Graft take failure occurred in 7.05% (6). Auditory gain of 30-35 dB in air conduction (AC) was found in 77.64% (66) and closure of a-b gap 20-30 dB was observed in 82.35% (70). 17.64% (15) children showed AC auditory gain of 20-30 dB, closure of a-b gap of 10-20 dB in 20% (17). No improvement in hearing was found in 4 (4.70%) children. Conclusion: Tympanoplasty improves hearing in children with CSOM if performed properly. As the follow-up in the study is only 14 months, a study with a longer follow-up would suggest a definitive conclusion.
