Frequency of improvement of proptosis for an underlying fronto-ethmoidal disease after lynch procedure

Objective: to determine the frequency of improvement in proptosis after lynch procedure in patients with fronto-ethmoidal lesions. material and methods: it was a descriptive case series study. the study was carried out in the department of ent unit-?,mayo hospital affiliated with the king edward medical university,lahore. the duration of the study was for six months (4th march,2010 to 3rd september,2010). a sample size of 70 cases was calculated with 95% confidence level,11% margin of error and taking expected percentage of improvement (cured) cases of proptosis to be 71%. results: in this study 70 patients,with fronto-ethmoidal disease and associated proptosis were included. there proptosis was measured using exophthalmometer. both pre-operative and post-operative proptosis was measured. and the results showed the mean age of the patients was 38.14±8.64 years with age range of 32(25-57) years. there were 50 males and 20 females in this study. so,the male to female ratio in this study was 2.5:1. the mean preoperative proptosis was 24±2.76 mm with range of 9(19-28)mm. the mean post-operative proptosis was 19.54±2.06 mm with range of 6(18-24)mm. after surgical procedure of lynch,in 42(60%) patients the proptosis was corrected and in 28 (40%) of the patients the problem persist with mean proptosis of 21.85±1.2mm.
