Transplantation with autologous fat granules to cure vocal cord sulcus

Abstract

Objective To discuss the effects of transplantation with autologous fat granules to cure vocal cord sulcus. Methods In this study we treated 32 cases of vocal cord sulcus with improved autologous fat grafting technique. Each case was treated 1-2 times and the interval period was 3-6 months. The result was based on comparing the size of fissure glottis, the surface area of the sick vocal cord and patients self evaluation. Results Long time follow up showed that fat graft can be alive in the recipient site for long time after 1-2 times autologous fat injection. More than 78.13% patients were satisfactory with the curative effect while less than 9.38% patients were unsatisfactory. Conclusions Autologous fat grafting technique is an effective and safe treatment for vocal cord sulcus. Key words: Autologous fat graft; Fat granule injection grafting; Vocal cord sulcus
