This prospective observational study aims to evaluate the relationship between anesthesia type and postoperative sleep quality in adult patients undergoing septoplasty. Patients will receive either total intravenous anesthesia or inhalational anesthesia as part of routine clinical care, without any intervention or modification to standard practice.
