Brow Fat Transposition for Reconstruction of Hollowing After Dermoid Cyst Excision on the Outer Upper Eyelid in a...

Periocular hollowing following tumor excision presents unique reconstructive challenges, particularly in young patients, as the literature on post-excisional reconstruction remains limited compared with that on age-related volume loss. We report the case of a 13-year-old female who presented with a dermoid cyst in the right upper eyelid causing mechanical ptosis. Following complete excision, a significant hollow developed at the surgical site. A single-stage reconstruction was performed using a pedicled brow fat (retro-orbicularis oculi fat) flap transposition to address the volume deficit. At the 18-month follow-up, excellent contour restoration and symmetry were achieved without complications. This case highlights that brow fat transposition offers a reliable, single-stage reconstructive option for upper eyelid hollowing following tumor excision, providing stable autologous volume augmentation with favorable aesthetic outcomes in young patients.
