Supramaximal Levator Resection for Poor Function Congenital Ptosis
The video (see Video, Supplemental Digital Content 1, available at https://drive.google.com/open?id=10uuVCNADWhLRWo_EE8gx5GK2nqz5mATW) demonstrates the technique previously described in the report by Cruz et al. for correction of poor levator function (<4 mm) congenital ptosis.1 Supramaximal levator resection refers to resection of the muscle above the Whitnall ligament. The amount of resection is based on the severity of the ptosis and the measured levator function: the more severe the ptosis and poorer the levator function, the more muscle resection required. The end-point of the surgery is to have the eyelid margin rest 1 to 2 mm below the super limbus with the patient under general anesthesia. In the author’s practice, supra-maximal levator resection has become the procedure of choice for unilateral, poor levator function congenital ptosis.
