Abstract

Although prior studies have identified a low risk of venous thromboembolism (VTE) in rhinoplasty, these studies are limited by small samples, and associated risk factors remain unknown.We sought to discern the incidence of VTE following rhinoplasty in a large patient population using a nationwide insurance claims database.Population-based retrospective analysis of insurance claims of patients who underwent rhinoplasty between 2007 and 2016. Established risk factors for VTE, demographic data, procedural details, and absolute incidence of VTE were collected.We identified a total of 55,287 patients who underwent rhinoplasty from 2007 to 2016. Mean age (SEM) was 38.74 ± 0.06 (range 18-74), and 54% were female. The overall incidence of VTE was 111, of which 70 were DVT, 41 were PE. On multivariate regression analysis, previous VTE (OR, 52.8, 95% CI, 35.2-78.6, p < 0.0001), PICC/central line placement (OR, 19.6, 95% CI, 9.8-153, p < 0.05), rib graft (OR, 4.6, 95% CI, 2.3-8.5, p < 0.0001), age 41-60 (OR, 2.65, 95% CI, 1.7-4.3 p < 0.01), IBD (OR 2.6, 95% CI, 1.0-5.5, p < 0.05), and age 61-74 (OR, 2.4, 95% CI, 1.2-4.8, p < 0.05) were associated with an increased risk of VTE.We demonstrate a low overall incidence of VTE in rhinoplasty patients. Previous VTE, PICC/central line, advancing age, IBD and intraoperative rib graft harvest were most strongly associated with VTE in this population cohort.
