Abstract
Background:
Complications associated with the use of autologous and homologous costal cartilage for nasal tip stabilizing grafts in septorhinoplasty are not well understood.
Objective:
The authors review current literature to evaluate complications associated with autologous and irradiated homologous costal cartilage (IHCC) used for septal extension and columellar strut grafts in rhinoplasty.
Method:
A comprehensive literature search was conducted in PubMed, Embase, Scopus, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov. Articles that used autologous or IHCC for either septal extension or columellar strut grafts in patients undergoing septorhinoplasty were included. The primary outcomes analyzed were postoperative complications.
Results:
A total of 14 studies representing 1358 patients were included. The pooled complication rate was 4.7%. IHCC grafts were associated with a higher incidence of complications (n = 21, 5.0% vs. n = 44, 4.6%, p = 0.01). Resorption was the most common complication in the IHCC group and occurred significantly more frequently than in the autologous costal cartilage (ACC) group (n = 10, 2.4% vs. n = 5, 0.49%, p = 0.002). Deviation/warping was the most common complication in the ACC group (n = 16, 1.7%).
Conclusion:
Autologous and irradiated homologous costal rhinoplasties remain safe procedures. The increased incidence of resorption associated with IHCC grafts should be considered during preoperative planning.
