Small incision external levator repair: technique and early results

Abstract

PURPOSE: To describe a new surgical technique and early results of external levator repair performed through a small skin incision. METHODS: A chart review of consecutive patients undergoing small incision external levator repair was conducted. This modified external levator repair was performed through an 8-mm eyelid crease incision. Patients with unilateral or bilateral aponeurogenic blepharoptosis were candidates for the technique. Patients with excessive horizontal upper eyelid laxity and those requiring blepharoplasty in addition to blepharoptosis surgery did not undergo this technique. Patients who underwent previous upper eyelid surgery or concurrent brow surgery were excluded from the review. Preoperative measurements included upper eyelid margin reflex distance, levator function, and degree of dermatochalasis, as well as Goldmann visual field results. Outcome measures included incidence and type of intraoperative complications, postoperative upper eyelid position (including margin reflex distance, eyelid contour, and symmetry), incidence and type of postoperative complications, and revisions or additional necessary surgery. RESULTS: Twenty-eight eyelids of 17 patients met study inclusion criteria. Preoperative margin reflex distance ± SD averaged 0.8 ± 0.4 mm. Average length of follow-up was 28 ± 5 weeks (range, 15 to 52 weeks). No significant intraoperative complications occurred. Postoperative margin reflex distance averaged 3.7 ± 0.3 mm. Two eyelids were mildly undercorrected, and one demonstrated moderately peaked contour postoperatively. Satisfactory eyelid position and contour were achieved in 25 of 28 treated eyelids. No patient elected reoperation. CONCLUSIONS: Early results demonstrated that small incision levator repair is safe and generally effective. This minimally invasive external levator repair is useful for a carefully selected subset of patients with aponeurogenic blepharoptosis.
