Comparison of Conjoint Fascial Sheath Suspension and Levator Muscle-conjoint Fascial Sheath Complex Suspension in...

The conjoint fascial sheath (CFS) has been widely utilized for blepharoptosis correction recently. However, the different effects of various surgical techniques and the intraoperative palpebral fissure height (PFH) under general anesthesia are unclear. Therefore, we compared and observed the effects of CFS suspension and levator muscle (LM)-CFS complex suspension under general anesthesia.

A retrospective analysis was performed on children with congenital moderate-to-severe blepharoptosis who underwent CFS suspension (group A) from January to December 2019 and LM-CFS complex suspension (group B) from January to December 2021. The main indices included the PFH, margin reflex distance 1 (MRD-1) value preoperatively and immediately, 1 day, 1 week, 1 month, and 6 months after surgery.

Thirty-six patients in group A and 51 patients in group B were included in the final statistical analysis. There was no significant difference in the preoperative mean PFH and MRD-1 values between the 2 groups (P > 0.05). The mean PFH and MRD-1 values in group B were significantly higher than those in group A at 6 months after surgery (8.05 ± 0.90 mm versus 6.75 ± 1.50 mm, P < 0.001; 3.71 ± 0.72 mm versus 2.64 ± 1.63 mm, P = 0.001). The postoperative satisfaction rate of patients in group B was significantly higher than that in group A (92.16% versus 72.22%, P = 0.013).

Compared with CFS suspension, LM-CFS complex suspension for the treatment of moderate-to-severe blepharoptosis in children under general anesthesia had better results, with relatively more stable PFH.
