1980 – 2012 Yılları Arasında Kliniğimizde Yapılan Blefaroptozis Cerrahisi Sonuçlarının Değerlendirilmesi
Abstract
The purpose of this study is to evaluate blepharoptosis surgery results in patients performed ptosis surgery in our clinics between 1980 and 2012, factors associated with surgical success and compatibility of margin-reflex distance with levator function in surgical method choice. For this purpose, patients performed ptosis surgery between 01.01.1980 and 31.12.2012, followed 6 months or more, 163 congenital (% 82,5), 37 acquired ptosis (% 18,5) total 200 patients with 226 eyes were included in the study. Postoperatively, cases with margin-reflex distance 3 mm and more was considered to be successful. Surgical success rates after first surgery was % 62,9 and improved to % 74,7 after all surgeries. Sex, trauma, visual acuity at diagnosis, eye movements, Bell phenomenon, age at surgery, fascia lata material were not associated with surgical outcome after first surgery and all ptosis surgeries; but high levator function and margin-reflex distance at diagnosis were associated with surgical success. In patients whose first surgery was levator resection, surgical success after first surgery and all ptosis surgeries were statistically significantly higher than patients whose first surgery was frontalis suspension. In choosing appropriate surgical technique, the cut-off point is determined as 4,5 mm for levator function, 0,5 mm for margin-reflex distance in both congenital ptosis group and all patients. For these cut-off points sensitivity, specificity and area under ROC curve were similar. Overall, these results suggest that margin-reflex distance is compatible with levator function in choosing appropriate surgical technique and margin-reflex distance can be used instead of levator function.
