Diced cartilage wrapped in blood products has been increasingly advocated in rhinoplasty. The complication is a major concern of the procedure. This meta-analysis aims to assess the complication rates and revision rate of this procedure.
All original articles published up to March 2022 were searched through PubMed, Embase, and Web of Science databases. Additional articles were added through reference searching. Articles were included for meta-analysis according to inclusion criteria. Data were extracted by 2 individuals independently and the analysis was conducted through Stata 12.0 software (StataCorp., College Station, Texas).
A total of 559 articles were initially found and an additional 1 article was added through reference searching. A total of 11 articles including 469 patients were included for meta-analysis. The results indicated that the total complication rates were 1.2% for irregularity, 0.2% for visibility, 0.7% for deviation, 1% for erythema, and 0% for graft resorption, depression, and infection. The revision rate was 1.2%.
The overall complication and revision rates of diced cartilage wrapped in blood products in rhinoplasty were relatively low. Considering the limited number of related studies, a larger sample size, long-term follow-up, clear diagnostic criteria, and detailed methods of measurement are expected in further research.
