Outcome of Y to V medial canthoplasty with medial canthal tendon plication for the correction of blepharophimosis syndrome

Abstract

AIM: Evaluation of the results of Y to V medial canthoplasty with medial canthal tendon (MCT) plication for the correction of blepharophimosis syndrome.

MATERIALS AND METHODS: Prospective interventional case series which included 15 cases of blepahrophimosis syndrome. Two stages management was used in all cases. The first stage was Y to V medial canthoplasty with MCT plication. 3 months later, ptosis was corrected by bilateral frontalis suspension or maximum levator resection in the more ptotic eyelid in patients with asymmetric ptosis. Data regarding margin reflex distance 1 (MRD1), horizontal palpebral fissure length (HPFL), inner intercanthal distance (IICD), and the ratio of IICD to HPFL were recorded before and after surgery and were statistically analyzed.

RESULTS: The mean age of patients was 3.7±0.8 years. According to the postoperative IICD/HPFL, 12 patients (80%) had successful outcome. The preoperative IICD had a mean of 37.6±1.5 mm, which was reduced post operative to a mean of 33.0±2.3 mm. The HPFL improved from preoperative mean 21±1.2 mm to postoperative mean 24.2±1.4 mm. The mean preoperative IICD/HPFL ratio was 1.8±0.2 which was reduced post operative to a mean of 1.37±0.2. The MRD1 improved from preoperative mean of 1±0.4 mm to 3.6±0.3 mm post operative. The main complication recorded was undercorrection which was observed in 3 patients (20%).

CONCLUSION: The two stage management using simple procedures as Y to V medial canthoplasty with MCT plication followed by frontalis suspension or maximum levator resection yielded satisfactory results in the correction of complicated deformity as the blepharophimosis syndrome.
