This retrospective study aims to compare the effects of low-flow and high-flow anesthesia techniques on intraoperative hemodynamics, neutrophil-to-lymphocyte ratio (NLR), and postoperative outcomes in patients undergoing tympanoplasty or myringoplasty. The data were collected from medical records of patients who underwent ear surgery between \[September 1, 2022\] and \[April 1, 2023\]. The study seeks to evaluate whether the choice of anesthetic flow rate has a significant impact on inflammatory response and recovery.
