A patient with congenital ptosis has a levator function of 3 mm. The preferred surgical procedure in this case is:

• A Müller's muscle-conjunctival resection (MMCR)
• B Levator aponeurosis advancement
• C Fasanella-Servat procedure
• D Frontalis suspension (brow suspension) using fascia lata ✓

Explanation

When levator function is severely reduced (≤4 mm), the levator muscle cannot generate adequate movement to correct ptosis — surgeries that rely on levator function (MMCR, aponeurosis advancement, Fasanella-Servat) will fail. Frontalis suspension (brow suspension) using autogenous fascia lata or a synthetic material harnesses the frontalis muscle to elevate the lid, providing adequate correction when levator function is poor. Fascia lata harvesting is possible in children over 3 years.
