The purpose of this study is to evaluate the rate of incidence and risk factor of postoperative nausea and vomiting (PONV) in patients who underwent orthognathic surgery. The subjects were 84 patients aged 1₅–₅2 years old (3₇ males and 4₇ females) who underwent orthognathic surgery under general anesthesia in Matsumoto Dental University Hospital from January 2011 to October 2016. The operation methods were sagittal split ramus osteotomy (SSRO) 44 cases, SSRO and Le Fort I osteotomy(Le Fort I)28 cases, SSRO, Le Fort I and genioplasty 6 cases, SSRO and genioplasty 4 cases, Le Fort I and anterior maxillary alveolar osteotomy 1 case, and SSRO, Le Fort I and genioplasty with upper and lower alveolar bone osteotomy 1case. Anesthesia was maintained with nitrous oxide or air in oxygen, sevoflurane or desflurane, remifentanil and fentanyl. The factors investigated were age, gender, minimum alveolar concentration hours (MAC hours), use of nitrous oxide, remifentanil dose, anesthesia time and the type of surgery. Statistical investigation was preformed using logistic regression analysis to confirm the significance between the incidence of PONV and follows; age, gender, MAC hours, use of nitrous oxide, remifentanil dose, anesthesia time and the type of surgery. The rate of incidence in nausea was ₇₇%, and that in vomiting was 3₅%. The incidence of nausea was 4.4 times higher in females than males. The incidence of vomiting was 4.6 times higher in cases with nitrous oxide than those without nitrous oxide.
