Chronic otitis media and subsequent hearing loss in children from the Himalayan region residing in Buddhist Monastic schools of Nepal

Abstract

ObjectivesThe main objective of the study was to ascertain the prevalence of chronic otitis media and determine the corresponding hearing loss in children from Nepal’s Himalayan region now residing in Buddhist Monastic schools of Nepal. MethodsThe study was conducted among children at Buddhist monastic school in different parts of Nepal. A total of 3174 children aged between 5 and 15 years, who were originally from the Himalayan region of Nepal and were currently residing in monastic schools, were screened for ear problems and hearing loss. They were examined by otoscope to diagnose chronic otitis media. Hearing was evaluated by pure tone audiometer, and 0.5–4 kHz air conduction hearing threshold was measured and documented. ResultsOf the total of 3174 children who were screened for ear diseases and hearing loss, monks constituted 76.21% (n = 2419) and Nuns 23.78% (n = 755). Chronic otitis media was the most common otoscopic finding during the screening, and it affected a total of 344 (10.83%) children. Out of these 344, hearing loss of varying degrees was observed in 5.42% (n = 172) children. ConclusionThere is high prevalence of chronic otitis media in children belonging to the Himalayan region of Nepal, and it is the main cause of avoidable hearing loss. Timely diagnosis and treatment of chronic otitis media could prevent unnecessary hearing loss in these children.
