Nakamura H, et al. - In this non-randomized, retrospective cohort study involving 106 patients, researchers analyzed the effect of skeletal muscle mass on surgical site infection (SSI) in flap reconstruction for defects after oral cancer resection. Participants in the study were patients who had this procedure after preoperative abdominal-lumbar CT. In univariate analysis, lower BMI, haemoglobin and skeletal muscle index (SMI) were significantly associated with recipient site SSI. A significant risk factor for recipient site SSI was lower SMI in a multiple logistic regression model. After resection of oral cancer and subsequent reconstruction, increasing skeletal muscle mass through exercise or diet before surgery can prevent recipient site SSI.
