ORBITAL COMPLICATIONS OF RHINOSINUSITIS IN A TERTIARY CARE HOSPITAL IN NEPAL

Abstract

Objective: The objective of this study was to determine the prevalence of orbital complications of rhinosinusitis in a tertiary care hospital of Nepal.

Materials and Methods: A retrospective study was conducted in the Department of Otorhinolaryngology of Tribhuvan University Teaching Hospital, Kathmandu, Nepal from January 2013 to December 2018. Ethical approval was obtained from the Institutional Review Committee. Patients of all age and gender diagnosed with orbital complications of acute and chronic rhinosinusitis were included in this study. The clinical records of 23 patients included in the study were reviewed. The diagnosis of rhinosinusitis was made according to European Position Paper on Rhinosinusitis and Nasal Polyposis. The classification of orbital complications of rhinosinusitis was done according to Chandler.

Results: Twenty three patients were diagnosed with orbital complications of rhinosinusitis during the five years of study duration. The prevalence of orbital complications of rhinosinusitis was found to be 0.35%. There were 12 (52.2%) cases of preseptal cellulitis, eight (34.8%) cases of orbital cellulitis, one (4.3%) case of subperiosteal abscess and two (8.7%) cases of cavernous sinus thrombosis.

Conclusion: The prevalence of orbital complications of rhinosinusitis is low in our centre. However, the result is comparable to other studies. Preseptal cellulitis was the commonest orbital complication of rhinosinusitis in this study.
