Among these, 197 (2.4%) had free flap failures necessitating a redo of either a free flap or a pedicled flap. Beyond comorbidities such as chronic obstructive pulmonary disease, end\u2010stage renal disease, and a history of prior radiotherapy, every 10\u2010unit decrease in the preoperative prognostic nutritional index (PNI) was consistently associated with an increased risk of both free flap complications and failure. The covariate\u2010adjusted odds ratios were 1.90 (95% confidence interval [CI]: 1.42\u20102.54) and 1.89 (95% CI: 1.13\u20103.17), respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A lower preoperative PNI suggests a higher likelihood of microvascular free flap complications in head and neck surgeries.
