Pak J Med Health Sci Jan ;12(3):1136-8.

Background The paranasal sinuses being adjacent to the orbits and its contents make them prone to surgical trauma by FESS done for diseases of the sinuses. Aim: To determine frequency of orbital cellulitis as result of FESS performed for CRS. Methods : This is a descriptive case series and it was conducted in 6 months from June , 2017 till December , 2017 at ENT Department, SGR hospital, Lahore. All 175 patients meeting inclusion criteria were inducted in the study from Department of ENT SGR hospital , Lahore. Patients underwent a complete Otolaryngoogical and Ophthalmic examination. CT scan of Paranasal sinuses was done. Results : In this study 175 patients meeting inclusion criteria were inducted. The mean age of patients was 38.92 +/- 11.61 years with age range of 20-60 years. There were 94(53.71%) male and 81(46.29%) female cases. The mean duration of disease was 21.85+/-5.26 weeks with minimum and maximum duration as 13 and 30 weeks. There were 18(10.29%) cases who developed orbital cellulitis after FESS. Conclusion: The orbital complications are less frequent after FESS for CRS. The incidence of such complications can be further prevented if we timely consider about extent of the disease and any previous surgery (FESS).
