Abstract

Objective: To analyze the incidences of long-term complications and revision surgery associated with diced cartilage grafts in dorsal augmentation rhinoplasty. Methods: The PubMed, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched for clinical studies on the use of diced cartilage for dorsal augmentation published. A meta-analysis was conducted to pool the estimated rates of infection, overcorrection, visible irregularity, absorption, and revision surgery. Result: A total of 14 studies involving 2380 patients were included in the systematic review. The combined rates were 11.5% for overall complications and 5.3% for revision surgery. The rates of the most frequently reported complications were 4.5% for infection, 5.3% for visible irregularity, 0.7% for overcorrection, and 0.5% for absorption. There was no significant difference in the rates of visible irregularity (p = 0.23) and revision surgery (p = 0.71) among the wrapped diced cartilage, glued diced cartilage, and free diced cartilage groups. Conclusion: This meta-analysis presents the first comprehensive and quantitative report of long-term complications associated with diced cartilage in dorsal augmentation rhinoplasty. Infection and visible irregularity were the most frequently reported complications. The rates of irregularity and revision surgery were not correlated with the diced cartilage packing methods.
