Levator Pull-Out Suture Technique for Immediate Postoperative Correction of Eyelid Asymmetry After Ptosis Surgery in Asians

Correction of Asymmetry of Palpebral Folds by Adopting Interrupted and Continuous Buried Suture Techniques Respectively on Different Eyelid

People with an obvious palpebral fold on 1 eye and a narrow or no palpebral fold on the other eye are usually more satisfied with the shape of the obvious palpebral fold and want to acquire symmetry by minimally invasive surgical methods that preserve the shape of the original folds they are more satisfied with. This study introduced a minimally invasive approach using 2 different buried suture techniques on different eyelids to acquire symmetry. The continuous suture method aimed to build palpebral folds, whereas the 3-point interrupted suture method aimed to enhance naturally formed palpebral folds. The 3-point interrupted buried suture method was used on the eye with an obvious palpebral fold, and the continuous buried suture method was performed on the eye with a narrow or no palpebral fold. Twenty patients underwent this procedure to correct the asymmetry between June 2010 and July 2022. The mean follow-up period was 18.12 months. The average swelling period was 7 days on the side using the interrupted buried suture technique and 10 days on the side using the continuous suture method. It took ~3 weeks to recover a relatively natural appearance. According to postoperative follow-up data, all patients were satisfied with the results. Our surgical approach of adopting 2 different buried suture techniques on different eyelids allowed the building of the palpebral fold on one eyelid while enhancing the original fold on the other eyelid, leading to satisfactory results of palpebral fold symmetry.

Müller Muscle-Conjunctival Resection for Treatment of Contralateral Ptosis following Unilateral External Levator Advancement

BACKGROUND

One of the main causes of unsatisfactory outcomes after unilateral blepharoptosis surgery is asymmetry of the upper eyelid height, which occurs as a result of a contralateral eyelid droop. Therefore, the authors evaluated the efficacy of Müller muscle-conjunctival resection (MMCR) for the treatment of contralateral ptosis following unilateral external levator advancement (ELA).

METHODS

This study analyzed 26 eyelids of 26 patients with upper eyelid height asymmetry following unilateral ELA who underwent contralateral MMCR retrospectively. The phenylephrine test was performed before ELA and before MMCR. The main outcome measures were symmetry outcomes and clinical outcomes.

RESULTS

The mean patient age was 55.81 ± 7.98 years (range, 44 to 70 years); 15 were female (57.7%). The Hering dependency was observed in 13 of the patients (50%) before ELA. An adequate response to phenylephrine was observed before MMCR but not before ELA. Symmetry outcomes after MMCR were perfect (<0.5 mm), good (≥0.5 mm and <1 mm), and fair (≥1 mm) in seven, 17, and two patients, respectively. An optimal upper eyelid height was noted in 47 of the 52 eyelids after the MMCR, whereas three of the 52 eyelids had minimal overcorrection, and two eyelids had undercorrection. The mean change in marginal reflex distance 1 of the contralateral eyelid droop was greater for patients with than without the Hering dependency ( P < 0.0001) after ELA but not after MMCR. Two patients (7.6%) underwent revision ELA surgery.

CONCLUSION

MMCR and use of the phenylephrine test to predict the eyelid position may represent an alternative approach in patients who require management of contralateral ptosis following unilateral ELA.

Efficacy of the Müller Muscle-Conjunctival Resection for the Correction of Unilateral Ptosis following External Levator Operations in Patients with Bilateral Involutional Ptosis

SUMMARY

Patients with aponeurotic blepharoptosis who are treated with external levator advancement may experience complications such as upper eyelid height asymmetry and often require revision surgery. The authors assessed the efficacy of Müller muscle-conjunctival resection in cases with upper eyelid height asymmetry following bilateral external levator advancement. The authors used retrospective analysis of 11 cases between September of 2016 and October of 2018 with eyelid asymmetry following bilateral external levator advancement. Following a positive phenylephrine test, these patients underwent unilateral Müller muscle-conjunctival resection revision surgery to treat the undercorrected eyelid. Preoperative and postoperative marginal reflex distance 1, symmetry outcomes, and clinical outcomes of patients were evaluated after the Müller muscle-conjunctival resection. The average patient age was 54.81 ± 3.95 years (range, 37 to 69 years; median, 56 years); seven patients (63.6 percent) were women. Hering dependency was seen in all patients before the external levator advancement. A total of three patients underwent bilateral external levator advancement simultaneously, and eight patients underwent bilateral external levator advancement sequentially. The phenylephrine test was positive in all patients before the Müller muscle-conjunctival resection. Symmetry outcomes were assessed after the revision surgery as perfect (<0.5 mm), good (≥0.5 to <1 mm), or fair (≥1 mm) in four patients, six patients, and one patient, respectively. An optimal correction was noted in 13 of the 22 eyelids after the revision surgery, whereas eight of the 22 eyelids had minimal undercorrection, and one eyelid had minimal overcorrection. Müller muscle-conjunctival resection revision surgery for treatment of the ptotic eyelid following bilateral external levator advancement is viable and may represent a new alternative among the limited revision techniques.

Adjustable Ptosis Correction via Posterior Levator Advancement With Minimal Superior Tarsectomy

PURPOSE

To report the surgical technique and outcomes for adjustable ptosis correction using a posterior levator advancement with minimal superior tarsectomy.

METHODS

A retrospective single-center study was conducted on patients who underwent adjustable ptosis repair via posterior levator advancement with minimal superior tarsectomy by a single surgeon from 2002 to 2018. Patients with greater than 1 mm asymmetry between eyes or contour abnormalities underwent nonsurgical adjustment in the office within 6 days of surgery.

RESULTS

A total of 79 patients (146 eyelids) were included in this study. The patients were female (67%), underwent bilateral surgery (87%) with mean age of 63 years (range, 20-92). The mean improvement in marginal reflex distance 1 at postoperative month 1 was 2.56 ± 1.04 mm (p ≤ 0.0001). Postoperative symmetry of 1 mm or less between eyes was achieved in 96.6% of patients. Only 8 eyes (5.4%) underwent in-office adjustment postoperatively. No demographic or clinical differences were noted in eyes that required adjustments. Postoperative complications included dry eyes that resolved by 3 months (13.6%), suture cyst (1.4%), corneal abrasion (1.4%), and persistent eyelid edema (1.4%). Surgical revision was required in 2.8% of eyes.

CONCLUSIONS

The adjustable posterior levator advancement with minimal superior tarsectomy is an effective surgical technique for ptosis repair with the added benefit of in-office adjustability to correct minor asymmetries.
