Background: Adenotonsillar hypertrophy is a common paediatric disorder in Otorhinolaryngological practice worldwide. The prevalence, clinical manifestations and predisposing factors are well documented in developed countries. However, available data shows differences between the various studies. There is paucity of data from developing countries. Thus, this study is aimed at assessing the age group distribution, predisposing factors, clinical manifestation and complications of adenotonsillar hypertrophy in a developing country. Methods: It is a prospective study of children under 10 years over a period of 24 months. Interviewer assisted questionnaire was administered.

Adenotonsillar hypertrophy affected all age groups studied. A high incidence was noted among the under 2 year olds. The Male: Female ratio was 2:1. Chronic cases constituted 55.7% of our study population. Common predisposing factors were atopy (73.9%), familial history (67.3%) and recurrent upper respiratory tract infection (58.2%). The Commonest clinical features were snoring, noisy breathing, tonsillar enlargement and narrowing of postnasal space air column. Failure to thrive, otitis media and rhinosinusitis were the commonly associated complications observed. No death was recorded. Conclusions: Adenotonsillar hypertrophy is common in our environment. It is important for all primary health care physicians, paediatricians and otorhinolaryngologists to have a clear knowledge on this ailment. Prevention or reduction in incidence is possible.
