Complications
Complications included infection (3.5%), necrosis (0.7%), septal perforation (0.5%), deep mucosal laceration (1.5%) and the loss of NFB during removal (1.2%). The overall complication rate was 5%. In multivariate analysis, increased risk for complications was associated with NFB-type (OR=6.5, p=0.01), multiple attempts to remove NFB (OR=6.4, p=0.01), posterior insertion of NFB (OR= 2.4, p=0.02) and left side insertion (OR=1.8, p=0.02). Characteristics of the cohort are presented in table 2.
