Autologous Fat Graft for the Treatment of Sighted Posttraumatic Enophthalmos and Sunken Upper Eyelid.

[PURPOSE] The treatment of enophthalmos and sunken upper eyelid is challenging. Although autologous fat graft has been widely used in breast augmentation, buttock contouring, and facial rejuvenation, its application in enophthalmos and sunken upper eyelid is not yet widely utilized. The clinical safety and value of autologous fat graft in sighted patients with enophthalmos and sunken upper eyelid are unclear. This study retrospectively analyzed the cosmetic results and safety of autologous fat graft in the correction of sighted traumatic enophthalmos and sunken upper eyelid.

[METHODS] Autologous fat graft was performed in 9 patients with posttraumatic enophthalmos and sunken upper eyelid. The visual acuity, orbital swelling, eye movement, enophthalmos, and sunken upper eyelid were observed.

[RESULTS] Eight to 24 months after autologous fat graft, enophthalmos and sunken upper eyelid in 9 patients improved significantly. Although orbital swelling occurred in the early postoperative period, no vision loss, eye movement limitation, or fat embolism had occurred.

[CONCLUSION] Autologous fat graft is an effective, predictable, scarless, and minimally invasive surgery for the correction of the sighted posttraumatic enophthalmos and sunken upper eyelid. The possible risk of fat embolization and blindness from the compression of the optic nerve should not be neglected. Further studies and more cases must be performed.
