Outcomes of Autogenous Dermis Fat Grafting with Different Donor Sites in Exposed Porous Orbital Implants

ABSTRACT

PURPOSE: To compare the outcomes of autogenous dermis fat grafting with different donor sites in the treatment of exposed porous orbital implants. METHODS: The present study retrospectively evaluated the medical records of 17 patients (17 anophthalmic eyes) who had undergone autogenous dermis fat grafting based on the diagnosis of exposed porous orbital implants and were regularly followed up for at least 12 months since the surgery from January 2001 to December 2010. The patients were divided into 2 groups (thigh and abdomen) according to the site of the donor grafting. The treatment outcome and complications were compared between the 2 groups. RESULTS: The success rate of thigh dermis fat grafting was 88.9% (8/9) and 100.0% (8/8) in the abdominal dermis fat grafting, and there was no statistically significant difference between the 2 groups (p = 1.000). Regarding ocular complications, graft tissue infection (thigh 11.1%, abdomen 0%) and superior sulcus deformity (thigh 22.2%, abdomen 25.0%) were present. Regarding donor site complications, tenderness (thigh 55.6%, abdomen 25.0%), dehiscence (thigh 22.2%, abdomen 25.0%) and scar formation (thigh 33.3%, abdomen 25.0%) were observed. In the gait associated complications, pain (thigh 55.6%, abdomen 25.0%) and limping (thigh 22.2%, abdomen 12.5%) were observed. The rate of all complications showed no statistically significant difference between the thigh dermis fat grafting and the abdominal dermis fat grafting (all p > 0.05). CONCLUSIONS: Thigh and abdomen can both be considered as an effective donor site for the autogenous dermis fat grafting in the treatment of exposed porous orbital implants.
