Abstract
To review the outcomes of frontalis suspension surgeries with the use of polytetrafluoroethylene in patients with blepharoptosis. A retrospective observational study analyzed the outcomes of frontalis suspension surgeries performed in a single institution from 2003 to 2018. All procedures were performed with closed incision and single pentagon techniques. Outcomes were classified as satisfactory or unsatisfactory, with satisfactory defined as a margin reflex distance of >3 mm and <1 mm between eyelids and unsatisfactory as hypocorrection, surgical complications, and asymmetry. We included a total of 76 eyelids from 52 patients in our study. Within a mean postoperative follow-up of 16.8 ± 18.5 months (range, 3-95), 59 (77.6%) eyelids had a satisfactory outcome, and 17 (22.4%) were unsatisfactory (8 cases of asymmetry, 3 granulomas, 3 suture extrusions, 2 abscesses, and 1 case of cellulitis). Nine eyelids from the unsatisfactory group required reoperation. Among the patients with a follow-up of ³12 months (38 surgeries), lasting results were observed in most eyelids, except for 2 late-onset suture extrusions. The use of polytetrafluoroethylene in frontalis suspension surgery was shown to be predictable, safe, and lasting. Our findings support previous studies that have shown adequate functional results and low complication rates.
Highlights
Blepharoptosis is a condition in which the upper eyelid margin is positioned at a lower level than normal in primary gaze[1]
Blepharoptosis is a common condition characterized by a low-lying upper eyelid (2 mm inferior to the upper limbus) in primary gaze
Other studies have shown an equal frequency between sexes[2], our study showed a significant predominance in the males (73%); our sample was smaller than those of other studies
Summary
Blepharoptosis is a condition in which the upper eyelid margin is positioned at a lower level than normal in primary gaze[1]. Blepharoptosis can affect vision and can lead to amblyo-.

The frontalis suspension (FS) technique is the treatment of choice in severe ptosis with poor levator muscle function (≤4 mm)(3). Various configurations and materials have been described to connect a sling from the upper eyelid to the frontalis muscle, which can be performed using a closed incision or an open incision technique[4]
