چکیده
Aim: To compare the effect of single rhomboid and double rhomboid frontalis suspension using 2 mm silicon band on upper lid contour in ptosis surgery. Methods: This randomized control study was conducted at the Department of Ophthalmology, Nishtar Hospital, Multan from March 2011 to March 2014. A total of 40 patients with unilateral ptosis were included in the study. Patients were divided into two groups A and B. Patients of group-A were operated by single rhomboid method and group-B were operated by double rhomboid method. Results: Overall 39patients came for follow up. 19 patients in group-A came for follow up while one patient lost to follow, however all 20patients of group-B came for follow up. 12 patients out of 19 in group-A showed lid contour symmetry while 3 out of 20 in group-B showed upper lid asymmetry. Conclusion: In this study we found that single rhomboid ptosis surgery has 4.2 times more relative risk for asymmetry of upper lid contour than double rhomboid silicon band frontalis suspension.
