Abstract (original English)

Lower eyelid scaring and malposition following violation of all three lamellae pose a significant ophthalmologic reconstructive challenge. The purpose of our study was to document a staged approach for this problem using: 1) transconjunctival scar release followed by palatal graft below the tarsal plate and subciliary scar release followed by full-thickness skin graft superficial to the tarsal plate and 2) subsequent autologous fat grafting to the lower eyelid. Cadaveric anatomic dissections were performed. Post-traumatic and post-surgical lower eyelid deformities requiring reconstruction were reviewed and outcome assessment was based on symptomatic improvement, perioperative complications, reoperations and long-term follow-up (> 1 year). Cadaver dissections demonstrated consistent lower eyelid tarsal plate and lamellar anatomy for the use of palatal graft and skin grafting. Clinically, 75% cases resulted from full thickness traumatic laceration of the lower eyelid or malar region and 25% of cases occurred after transconjunctival incisions were made for zygomatic maxillary repositioning following partial lower eyelid laceration. Preoperative symptoms of: epiphora, tearing, redness, blurry vision and dryness improved in all patients and complete resolution was seen in 63% of patients. Thirty-seven percent of patients had complications: Redundancy of palatal graft, Partial FTSG l
