The Utility of Preoperative Phenylephrine Testing in Müller Muscle Conjunctival Resection Surgery for Involutional Ptosis.

Ophthalmic plastic and reconstructive surgery·2025

Sutureless conjunctiva-sparing Müllerectomy (CSM) offers comparable eyelid elevation to Müller muscle-conjunctival resection (MMCR) in pediatric ptosis repair. This technique significantly reduces operative time, making it a safe and efficient alternative.

Area of Science:

  • Ophthalmology
  • Pediatric Surgery

Background:

  • Ptosis, or drooping eyelid, affects children and can impact vision.
  • Traditional Müller muscle-conjunctival resection (MMCR) is a common surgical approach.
  • Sutureless conjunctiva-sparing Müllerectomy (CSM) is a newer technique aiming for improved efficiency.

Purpose of the Study:

  • To compare the efficacy and safety of sutureless CSM versus MMCR for pediatric ptosis repair.
  • To evaluate outcomes such as eyelid elevation, symmetry, operative time, and complications.

Main Methods:

  • Retrospective comparative study of pediatric patients (<18 years) with mild ptosis and good levator function (≥10 mm).
  • Patients underwent either sutureless CSM or MMCR.
  • Primary outcomes: change in margin-reflex distance 1 (ΔMRD1) and postoperative symmetry. Secondary outcomes: operative time, complications, reoperation.

Main Results:

  • Thirty-three eyelids were analyzed (13 CSM, 20 MMCR).
  • Both techniques yielded similar mean ΔMRD1 (1.2 mm vs. 1.3 mm) and symmetry (0.7 mm vs. 0.8 mm).
  • Sutureless CSM had a significantly shorter operative time (7.5 min vs. 13.5 min per eyelid; P=0.001), with comparable reoperation and complication rates.

Conclusions:

  • Sutureless CSM provides comparable eyelid elevation and symmetry to MMCR in pediatric ptosis repair.
  • The technique significantly reduces surgical time, indicating it's a safe and efficient alternative.
  • This supports the adoption of sutureless CSM for pediatric ptosis surgery.
