Preoperative evaluation characteristics of bimaxillary surgery patients: A retrospective study in which prominent findings were evaluated with the literature review

In this study, we aimed to share our experience in preoperative anaesthesia evaluation for patients undergoing bimaxillary surgery in our hospital and review the relevant literature. We retrospectively evaluated 139 patients with ASA (American Society of Anesthesiology) physical status 1 and 2 who underwent bimaxillary surgery. Data were collected on demographic characteristics, ASA physical status, mallampati scores, systemic diseases, allergy history, consultation request status, consulted departments, smoking, alcohol or drug use, and previous exposure to general anaesthesia. The preoperative evaluation of bimaxillary surgery patients revealed several notable findings, including a relatively high rate of cardiovascular problems (48% rate among those with additional systemic disease), the need for otolaryngology (ENT) consultation being the most frequent (44% rate among all consultations), and a relatively high rate of active smoking (23.7%). Our findings suggest that the bimaxillary surgery patient group should be carefully evaluated, particularly regarding cardiovascular disease and difficult airway management
