Abstract
INTRODUCTION
Grafts play key roles in functional and aesthetic rhinoplasty. Autologous grafts are generally preferred for their biocompatibility and less visibility when used in a fragmented fashion. The aim of this study was to review mechanically fragmented cartilage grafts techniques described in the literature, outlining indications, outcomes, and complications.
MATERIAL AND METHODS
A systematic review of articles published from 1999 until December 2022 was conducted, using the following key words: "rhinoplasty," "cartilage," and "graft." Studies were selected according to the inclusion and exclusion criteria, and data were extracted and grouped for subgroup analysis. Rates of partial resorption, total resorption, surgical revision, and major and minor complications were statistically analyzed.
RESULTS
Thirty eligible studies were included. Three cartilage fragmentation methods were identified: diced, shaved, and crushed. Cartilage grafts were further divided into injectable and noninjectable grafts. Diced cartilage was the most commonly used. Dorsal irregularities were the main indication. Overall, 1.68% of patients experienced partial resorption, 0.27% experienced total resorption, and 1.46% needed revision. The partial resorption rate in the diced group was significantly lower than that in the shaved group. Injectable grafts showed a higher rate of partial resorption. The revision rate was higher with noninjectable grafts.
CONCLUSION
The partial resorption rate was lower in patients treated with diced cartilage. Injectable grafts are malleable and suitable for the correction of minimal irregularities, although they are affected by a higher rate of partial resorption. Wrapping materials may be used when significant augmentation is required.
