  • Title: Treatment of Tear Trough Deformity: Fat Repositioning versus Autologous Fat Grafting.
    Author: Chiu CY, Shen YC, Zhao QF, Hong FL, Xu JH.
    Journal: Aesthetic Plast Surg; 2017 Feb; 41(1):73-80. PubMed ID: 28008460.
    Abstract:
    BACKGROUND: Fat-preserving lower blepharoplasty techniques and filling techniques using autologous or non-autologous materials are increasingly used to treat tear trough deformity. However, there has been no definitive comparison of the results of fat repositioning versus autologous fat grafting for this condition. The authors used statistical analysis to compare the results of the two methods. METHODS: From October 2013 to September 2015, a total of 101 patients, aged 20-43 years, underwent fat repositioning or autologous fat grafting in our department. Group 1 (51 patients, 102 eyes) underwent intraorbital fat repositioning with septal reset by transconjunctival lower blepharoplasty. Group 2 (50 patients, 100 eyes) underwent autologous fat grafting by lipoinjection. RESULTS: No significant complications occurred in any patient postoperatively. Four of 102 eyes in Group 1 and seven of 100 eyes in Group 2 had no improvement; the rest had different degrees of improvement. In Grade II and III deformities, fat repositioning resulted in significantly greater improvement of grade compared with autologous fat grafting. The surgical method of Group 1 resulted in better curative effects than that of Group 2. CONCLUSION: In patients with tear trough deformity and without obvious skin or orbicularis oculi muscle laxity, both fat repositioning and autologous fat grafting are acceptable for mild deformity. In patients with higher-grade deformities, fat repositioning produced superior results than autologous fat grafting.
