title: Comparison of nylon monofilament suture and polytetrafluoroethylene sheet for frontalis suspension surgery in eyes with congenital ptosis.
abstract: OBJECTIVE
  To compare nylon monofilament suture with polytetrafluoroethylene sheet for frontalis suspension surgery to treat eyes with congenital ptosis.
  
  
  METHODS
  Retrospective, nonrandomized, comparative, interventional case series.
  
  
  METHODS
  We reviewed the medical records of 49 patients who had undergone 79 eyelid frontalis suspension surgeries to treat congenital ptosis. All of the patients were younger than 16 years and had congenital ptosis with poor levator muscle function. They were treated with frontalis suspension surgery with either a nylon suture or a polytetrafluoroethylene sheet and were followed up for at least 1 year. A single rhomboid loop sling was used for the nylon suture surgery. For the polytetrafluoroethylene sheet, an incision was made in the eyelid crease, and one end of the sheet was fixed to the tarsus and the other was fixed to the frontalis muscle. The main outcome measures were postoperative recurrences and complications.
  
  
  RESULTS
  We evaluated 37 eyelids of 25 patients after nylon suture surgery and 42 eyelids of 31 patients after polytetrafluoroethylene sheet surgery. Among these, 9 eyelids of 7 patients were included in both groups. The median postoperative follow-up period was 32 months in both groups. The recurrence rates were 62.2% for the nylon suture group and 0% for the polytetrafluoroethylene sheet group (P < .001). The postoperative complication rates were 0% for the nylon suture group and 7.1% for the polytetrafluoroethylene sheet group (P > .05).
  
  
  CONCLUSIONS
  Frontalis suspension using a polytetrafluoroethylene sheet with direct tarsus and frontalis muscle fixation is a reasonable technique with low rates of recurrences and complications.
