Correction of Tear Trough Deformity Using Autologous Fibroblast Combined with Keratin: New Soft Tissue Filler.

OBJECTIVE

To evaluate the effectiveness and safety of autologous fibroblasts combined with keratin gel for tear trough deformity rectification as injectable soft tissue filler.

MATERIALS AND METHODS

The new injectable soft tissue filler was derived from autologous fibroblasts and keratin gel. A total of 35 patients received treatment of this filler injection for tear trough deformity rectification. All the patients were followed up, and the clinical features including photographs and satisfaction were collected and assessed at 1, 3, 6, 12 and 24 months after injection. The efficacy of each patient was evaluated independently by blinded evaluators at different time points. All patients consented to publish identifiable photographs in this study.

RESULTS

Tear trough deformity was improved even at 18-24 months post-injection. No severe adverse effects were observed resulting from the filler injection.

CONCLUSION

Combination of autologous fibroblasts and keratin is efficient and safe for correction of the tear trough deformity with long-term satisfaction and desirable result.
