Abstract
Diced cartilage grafts are used to increase and refine the nasal contour, providing
easy molding and versatility when compared with block grafts. However, all grafts
present the possibility of visibility, distortion, and absorption. The aim of this
study is to evaluate, through a systematic review, the outcome of the use of the free
diced graft cartilage in rhinoplasty. A systematic search of the literature was performed
in the databases (PubMed, Lilacs, Scielo, Cochrane) with the terms “diced cartilage”
and “rhinoplasty.” Studies were selected according to the inclusion and exclusion
criteria and data extracted and grouped for analysis. Six eligible studies were included.
In total, 4,044 patients underwent rhinoplasty with free diced cartilage graft, with
61 (1.51%) of them requiring reoperation. The main reasons were overcorrection and
irregularities of the nasal dorsum. The infection rate was reported in three studies,
with 2 (0.06%) of 3,252 patients presenting infection at the graft site. Two cases
of displacement were treated with external molding, without reoperation. The graft
resorption was reported in four articles, which described 22 (0.67%) cases of partial
resorption in 3,288 patients. Therefore, the available evidence suggests that resorption
of the graft and unfavorable outcomes are rare.
