Effectiveness of Cross-Linked Acellular Dermal Matrix to Correct Post-Traumatic Enophthalmos

The use of an acellular dermal matrix is rarely reported in orbital wall fracture reconstruction. This study aimed to share the author's experience with the cross-linked acellular dermal matrix as an allograft material for enophthalmos correction.

In this retrospective study, the author evaluated the medical records and 3-dimensional facial computed tomography scans of patients with enophthalmos caused by neglected orbital fractures between May 2021 and June 2022. Facial computed tomography scans confirmed the clinical diagnosis of enophthalmos. A single surgeon performed all surgical operations. In all patients, the author accessed the orbital floor via subciliary incision while approaching the medial wall with a retrocaruncular incision. After fully exposing the lesion, the author used a 1.0-mm-thick cross-linked acellular dermal matrix (ADM) (MegaDerm; L&C Bio, South Korea). After trimming the cross-linked ADM to a proper size, the author implanted the ADM into the lesion.

During May 2021 and June 2022, 3 cases of enophthalmos were successfully corrected with cross-linked ADM at the author's hospital. All patients were improved clinically and radiologically.

This is the first study to show the effectiveness of cross-linked ADM for the correction of enophthalmos.
