Septorhinoplasty and Septoplasty: Outcomes of a Large Cohort Using Autologous Versus Homologous Cartilage, 1999-2019.

This study describes the complication rate and use of autologous and/or homologous cartilage in a large 20-year cohort of septo(rhino)plasty surgeries in a Dutch hospital, in relation to postoperative complications of septo(rhino)plasty surgery described in previous studies. A retrospective medical chart review was conducted. 2606 patients, mean age 34.7 (± 13.2) and 59.9% male, underwent primary or revision septo(rhino)plasty surgery from 01/01/1999 to 01/09/2019. Follow-up was known in 1384 of 2606 patients (53.1%) with a mean duration of 47.5 months. Complication registration was complete for 1774 patients. The overall complication rate was 270 out of 1774 (15.2%). The use of autologous costal cartilage (ACC) was a risk factor for overall complication with an odds ratio (OR) of 11.1 (95% CI 0.03-0.30; P < 0.01) as compared to 5.9 (95% CI 0.06-0.45; P < 0.01) when using homologous costal cartilage (HCC). Infections were more likely when ACC (5/26 [19.2%]) was used than when HCC (1/28 [3.6%]) was used. Notable resorption of cartilage was more likely when HCC (9/28 [32.1%]) was used than when ACC (1/26 [3.8%]) was used. Both the use of autologous costal cartilage grafts (OR 11.1) and homologous costal cartilage grafts (OR 5.9) lead to an increased risk of complications. When choosing cartilage type for reconstruction in septo(rhino)plasty, it should be taken into account that both ACC and HCC are associated with a higher risk of complications.
