Hemoglobin–Albumin–Lymphocyte–Platelet (HALP) Score as a Predictive Model for the Success of Reconstruction of Head and Neck Defects with Free Microvascular Flaps

Significant advances in reconstructive head and neck surgery with free microvascular flaps have had a positive impact on esthetic outcomes quality of life. However, complications still occur some patients. This study investigated the influence Hemoglobin, Albumin, Lymphocyte, Platelet Score (HALP score), an immunonutritive marker, flap success. The retrospective analysis included 194 patients who underwent reconstruction defects flaps. HALP score correlated strongly overall complications, including necrosis, infection, fistula, hematoma. albumin, lymphocytes, platelets individually showed associations specific complications. was extremely strong predictor (AUC = 0.85). may be valuable for assessing patient status predicting free-flap to allow timely interventions improve outcomes. Further research is needed investigate additional predictors postoperative care.
