Preoperative hypovitaminosis D and complications in plastic surgery: a pilot study.

Vitamin D plays a crucial role in various biological processes, including the well-known regulation of the immune system and calcium metabolism. While its involvement in the surgical outcomes of various medical specialties is recognized, there is a lack of consistent data regarding plastic surgery. This study aimed to assess preoperative serum levels of 25-hydroxyvitamin D and its relationship with complications in patients undergoing reconstructive and aesthetic plastic surgeries. prospective and observational cohort study, conducted from October 2021 to August 2023 at the Hospital das Clínicas, Universidade Federal de Pernambuco, involving 83 patients. vitamin D levels were deemed deficient in 7 (8,4%) patients, insufficient in 36 (43,4%), and sufficient in 40 (48,2%). No direct association was demonstrated between deficient or insufficient serum levels of 25-hydroxyvitamin D and the incidence of complications in plastic surgery, even when considering comorbidities. preoperative hypovitaminosis D was not associated with complications in plastic surgery.
