Comparing Minimally Invasive Modified Levator vs. Conjoint Fascia Sheath-Levator Suspension in Correcting Severe Congenital Ptosis.

PURPOSE: To analyze the clinical efficacy and differences between minimally invasive modified levator palpebrae complex and conjoint fascia sheath-levator muscle complex suspension surgeries in correcting severe congenital ptosis.

METHODS

This retrospective analysis included 40 patients with severe congenital ptosis, of whom 22 (25 eyes) and 18 (21 eyes) underwent minimally invasive modified levator palpebrae complex and conjoint fascia sheath-levator muscle complex suspension, respectively. Palpebral fissure height, marginal reflex distance 1, scleral exposure, and eyelid mobility at 1 week and 1 and 3 months postoperatively were compared between the surgical groups.

RESULTS

The overall correction rates did not differ significantly between the minimally invasive modified levator palpebrae complex and conjoint fascia sheath-levator muscle complex suspension surgeries (88% vs. 66.67%). At 1 month postoperatively, the average scleral exposure was significantly lower in the modified levator palpebrae complex group than in the conjoint fascia sheath-levator muscle complex group (1.28 ± 1.29 mm vs. 2.17 ± 0.96 mm). Additionally, at both 1 and 3 months postoperatively, eyelid mobility was significantly greater in the modified levator palpebrae complex group than that observed in the conjoint fascia sheath-levator muscle complex group (6.84 ± 1.16 mm and 7.08 ± 1.18 mm vs. 5.54 ± 1.43 mm and 5.91 ± 1.69 mm).

CONCLUSION

Both minimally invasive modified levator palpebrae complex and conjoint fascia sheath-levator muscle complex suspension surgeries effectively correct severe congenital ptosis; however, the former demonstrates superior eyelid mobility and closure function recovery as postoperative outcomes.
