Abstract
Background: To compare the surgical outcome of unilateral silicone sling with bilateral fascia latafrontalis suspension surgery for severe unilateral congenital ptosis.Subjects and Methods:This prospective, interventional and comparative study examined 30 patients of severe unilateral congenital ptosis. 30 patients were divided in to 2 groups, group 1 included 15 patients who underwent unilateral silicone sling frontalis suspension surgery and group 2 included 15 patients who underwent contralateral levator excision with bilateral fascia latafrontalis sling surgery.Results:Mean improvement in MRD1 after surgery in group 1 who underwent unilateral silicone sling surgery was 3.9+1.18 mm and in group 2 who underwent bilateral fascia lata it was 4.9+0.89 mm (p value 0.0001). Excellent results (difference of lid height <1 mm) were seen in 93.3% patients who underwent bilateral fascia latafrontalis sling while in 73.3% patients of unilateral silicone sling. All patients who underwent bilateral fascia lata showed excellent lid crease (symmetric without obliteration) and 80% of the patients who underwent unilateral silicone sling surgery (p value 0.032).Conclusion: Functional and cosmetic outcomes regarding MRD1, symmetry of lid height, lid crease were noted better in group 2 patients who underwent contralateral levator excision with bilateral fascia latafrontalis suspension surgery as compared to group 1 patients who underwent unilateral silicone sling surgery.
Highlights
Blepharoptosis or ptosis is defined as an inferior malposition of the upper eyelid margin with respect to the superior corneo-scleral limbus.[1]
Congenital ptosis is mainly due to myogenic dysgenesis of the levator muscle means instead of normal muscle fibres, fibrous and adipose tissues are present in the muscle belly
Ptosis correction was measured by MRD1 and symmetry of lid height
Summary
Blepharoptosis or ptosis is defined as an inferior malposition of the upper eyelid margin with respect to the superior corneo-scleral limbus.[1]. Some authors advocate excellent results in patients who underwent unilateral frontalis sling It gives advantage of preserving the healthy eyelid in unilateral ptosis patients. To compare the surgical outcome of unilateral silicone sling with bilateral fascia lata frontalis suspension surgery for severe unilateral congenital ptosis. Excellent results (difference of lid height
