Infrequently found in the head and neck region, it can cause local or neurologic symptoms depending on its location and interaction with cranial nerves. While uncommon, it is an important diagnosis to have on the differential of periorbital lesions as surgical removal and prognosis are generally good.

Biomechanics of the Levator Aponeurosis.

Purpose: To investigate biomechanical properties of the levator aponeurosis.

Methods: Patients undergoing external levator resection for primary or revision correction of acquired ptosis were analyzed as primary and revision groups. Immediately postoperatively, the resected segments of the levator aponeurosis were stressed by adding sequential masses to the tissue.
