Abstract

Summary: Background: The use of irradiated homologous costal cartilage (IHCC) as an alternative source of graft material for rhinoplasty remains controversial because of the risk of complications. Herein, we aimed to perform a comprehensive assessment of complications associated with IHCC use in rhinoplasty through a meta-analysis of published studies. Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify eligible published studies, and we evaluated the complication rates of IHCC use in rhinoplasty. Published studies meeting the inclusion criteria included clinical studies involving at least 10 patients and assessing at least 1 postoperative long-term complication of rhinoplasty. Two investigators independently extracted data from the included studies using a standardized form. Meta-analysis was performed using a random-effects model. The main outcomes were the rates of various complications, including the need for revision surgery. Results: Ten studies involving a total of 959 patients were analyzed. The complication rates were 2.07% (95% confidence interval [CI], 0.80%–5.23%) for warping, 1.77% (95% CI, 1.10%–2.83%) for infection, 1.34% (95% CI, 0.34%–5.16%) for resorption, 2.13% (95% CI, 0.86%–5.19%) for displacement, 2.99% (95% CI, 1.24%–7.03%) for revision, 0.16% (95% CI, 0.01%–3.25%) for extrusion, and 2.04% (95% CI, 1.02%–4.02%) for avulsion. All the included trials had moderate-to-high methodological quality except for small sample sizes and subjectively reporting of some complications. Conclusions: The overall long-term complication rates associated with IHCC use in rhinoplasty were low. Revision and displacement were the most common complications at the one-year follow-up; surgeons should pay special attention to the risk of these complications. IHCC can serve as a reliable material for rhinoplasty and achieve good patient satisfaction.
