Levator resection is a ptosis surgery that shortens the levator muscle to increase its lifting power. It is typically used in congenital ptosis with moderate levator function.
Surgical Approach
Through an upper lid incision, a segment of levator muscle and aponeurosis is resected and reattached closer to the tarsal plate. The amount removed depends on pre‑operative levator measurements and desired lid height.
- Provides stronger elevation than simple advancement in poorly functioning muscles
- Requires intraoperative assessment to avoid overcorrection
- Often combined with creation of a lid crease for cosmetic symmetry
- General anaesthetic is usually needed, particularly in children
Outcomes
Levator resection can significantly improve eyelid position and visual field. However, risk of incomplete closure and exposure is higher in very large resections.
- Post‑operative lubrication and sometimes taping at night protect the cornea
- Follow‑up evaluates lid height, contour, and ocular surface health
- Occasional revisions may be necessary as tissues remodel or children grow
- Timing is balanced against risk of amblyopia and anaesthetic considerations
