Abstract

Objective

To find the feasibility, functional and cosmetic outcome of frontalis brow suspension surgery in simple congenital ptosis.

Study design

Descriptive case series.

Place & Duration of study

Institute  of Ophthalmology, Liaquat University of Medical & Health Sciences Jamshoro,  from October 2019 to December 2020.

Methodology

Patients visiting the outpatient department and meeting the inclusion criteria of having severe congenital ptosis with poor levator function <4mm, were included in this study. Patients with variable ptosis, diplopia, fair to excellent levator function and presence of Marcus Gunn Jaw winking ptosis were excluded. The variables assessed included margin reflex distance and palpebral fissure height. The outcome was graded as excellent, good or poor based on follow up at 6th month post-surgery. Statistical analysis was done by SPSS version 21.

Results

Out of 52 patients, 32 (61.5%) were males and 20 (38.5%) females with the mean age of 14.18±5.43 year. Total of 56 eyes of 52 patients were associated with ptosis. We measured the functional outcome of the surgery by comparing mean preoperative and postoperative margin reflex distance (MRD) which was 0.5±0.98 mm, and 3.31±0.74 mm respectively. The mean preoperative and postoperative palpebral fissure height (PFH) was 4.96±1.35 mm, and 9.07±1.21 mm respectively. Majority of the patients had good to excellent cosmetic results. One (1.92%) patient had poor cosmetic outcome and required knot revision.

Conclusion

Frontalis bow suspension surgery in case of congenital ptosis was found safe and effective in providing the better functional and cosmetic results, short hospital stay with minimal postoperative problems.
