Abstract

Abstract : Background: Autologous material remains the preferred graft material for use in rhinoplasty. However, resorption rates of autografts remain controversial. In addition, long-term follow-up studies on autografts are rare. Thus, the objective of the present study was to access long-term resorption rates of various autologous grafts on the upper nasal third. Methods: Medical records of patients who had undergone septorhinoplasty with dorsal augmentation using autologous tissues between 2009 and 2018 were retrospectively reviewed. Autogenous grafts applied on the nasal dorsum were categorized into three groups: rolled superficial mastoid fascia, diced cartilage wrapped with superficial mastoid fascia, and rolled sacral dermis. Preoperative and postoperative photographs were used to evaluate resorption rates and projection. Results: The rolled sacral dermis group showed a steep increase in postoperative projection but a sharp decrease in long-term follow-up projection compared to the other two groups. Among these three groups, there were statistically significant trend differences in rhinion ( p < 0.001) and ½ nasion-rhinion point ( p < 0.001), but not in nasion. Of these three groups, the rolled sacral dermis group showed the most projection, followed by the diced cartilage wrapped with superficial mastoid fascia group. The resorption rate was the highest in the rolled superficial mastoid fascia group ( p < 0.001). Regarding resorption rates in the other two groups, the rolled sacral dermis group had a higher rate than the diced cartilage wrapped with superficial mastoid fascia group. Conclusions: At least 50 percent of resorption was observed in almost all groups in the long term. The choice of graft material and proper decision-making could determine success or failure.
