Incidence and Predisposing Factors of Postoperative Infection after Rhinoplasty: A Single Surgeon's 16-Year Experience with 2630 Cases in an East Asian Population.

[BACKGROUND] This study evaluated the incidence and clinical characteristics of postoperative infection following rhinoplasty.

[METHODS] This article is a retrospective review of 2630 East Asian rhinoplasty cases performed by a single surgeon (Y.J.J.), from July of 2003 to June of 2018. There were 1595 male patients (69.9 percent) and 687 female patients (30.1 percent), and the median age was 31 years. The incidence of infection was compared between primary and revision cases and analyzed according to the materials used. The authors evaluated the organisms cultured and the timeframe of infection development and intervention.

[RESULTS] There were 2134 primary and 496 revision cases. Materials included autologous costal cartilage (413 cases), conchal cartilage (572 cases), homologous fascia lata (829 cases), homologous costal cartilage (102 cases), Gore-Tex (373 cases), and silicone (32 cases). The authors identified 22 cases (0.84 percent) of postoperative infection, 18 of which were revision. Revision surgery had a 19-fold greater infection rate than primary surgery (3.63 percent versus 0.19 percent). Women were 3.6 times as likely to develop an infection ( p = 0.002). The infection rate using autologous costal cartilage was 3.39 percent, and that for simultaneous correction of a septal perforation was 8.57 percent. In 11 cases (50 percent), infection developed within 1 month after surgery (12 ± 7 days). Methicillin-resistant Staphylococcus aureus was cultured in eight cases. Infection manifested at the nasal tip in 45 percent and the caudal septum/columella in 32 percent of cases. Twenty cases (90.9 percent) underwent surgical débridement.

[CONCLUSION] Revision rhinoplasty in women, requiring the use of costal cartilage or simultaneous correction of septal perforation, showed a higher risk of postrhinoplasty infection, which usually manifested at the nasal tip and caudal septum/columella and needed to be managed by surgical débridement.
