The Effect of Two Different Frontalis Sling Approaches on Postoperative Eyelid Contour: A Comparative Study

Purpose To compare two different frontalis sling approaches, tarsal fixation and orbicular muscle fixation, using silicone rod (FCI Ophthalmics, Marshfield Hills, MA, USA) in terms of postoperative upper eyelid contour in patients with poor levator muscle function. Design Retrospective, comparative, case series. Methods Ten eyes of seven patients who received frontalis sling surgery with orbicularis muscle fixation (group 1), eight eyes of seven patients who received frontalis sling surgery with tarsal fixation (group 2) and 30 eyes of 15 age and sex-matched healthy controls (control group) were included. Postoperative photographs of all the participants were taken in the primary gaze, and each photograph was viewed on a computer. The distance between the upper lid margin and pupillary center (MCD), nasal limbus (MND), and temporal limbus (MTD) was measured, respectively, using the ruler in Microsoft Paint Software and compared with each other for each participant. Results Both nasal, central and temporal margin distance values in group 1 and group 2 were significantly lower than those of the control group ( p
