Atrophic Rhinitis with Maggot Infestation- A Demographic Study
Abstract
Introduction: Atrophic rhinitis is a chronic nasal condition characterised by atrophic changes in the nasal mucosa and the underlying bones. This leads to the formation of abnormally roomy nasal cavities, anosmia, foul smelling greenish crusts, epistaxis and occasionally maggot infestation in the nose. The present work has been undertaken to study the demographic features of atrophic rhinitis with maggot infestation (Myiasis) in a population in North Karnataka. Aim: To study maggot infested atrophic rhinitis cases with respect to age and sex distribution, anaemia association, clinical (unilaterality/bilaterality) presentation and seasonal variation. Materials and Methods: This was a retrospective study. As per the records maintained by OPD of ENT Department, Bidar Institute of Medical Sciences, Bidar., between 2006 and 2015, there were 190 reported cases of atrophic rhinitis. Of these, 33 cases showed maggot infestation and were admitted for treatment. The detailed records of these patients were available and collected. This formed our study group. The patients of atrophic rhinitis without Nasal Myiasis were treated on outpatient basis. Details of age, sex, unilaterality, bilaterality, with /without anaemia, seasons, were tabulated and observations discussed. Results: Prevalence of maggot infested atrophic rhinitis cases were 17.4%. Maximum number of cases were seen in the age groups of 45-64 years and 65 years and above. Female predilection was seen with a female:male ratio of 3.1:1. Rural living conditions and anaemia proved to be playing a role in its higher prevalence. With respect to seasonal variation, more number of maggot infested atrophic rhinitis cases were clustered around the months of October, November and December. Conclusion: Atrophic rhinitis with nasal myiasis is multifactorial disease having a female predilection, association with older age group, poor nutrition and anaemia. Patients from rural area were more prone for nasal myiasis. It also shows a seasonal variation with more incidence in the relatively cooler months of October, November and December.
