Many patients who will undergo surgery experience varying degrees of anxiety and fear in the preoperative period. The aim of this study is to investigate the effects of preoperative detailed information on postoperative pain and anxiety levels in rhinoplasty surgery. A total of 64 patients between the ages of 18-65, in ASA I-II class, and undergoing rhinoplasty surgery were included in this study. The patients were randomized into two groups as group B and group N. Patients in Group B were informed in detail about the anesthetic and surgical procedure. Only routine information was given to the patients in Group N. Preoperative anxiety levels of all patients were measured with the STAI FORM TX-1 anxiety scale. Anxiety levels were re-measured at the 3rd postoperative hour and pain levels were evaluated with the VAS score and recorded. Preoperative anxiety levels and 3rd hour VAS scores were found to be similar in both groups. The anxiety level measured at the 3rd postoperative hour was found to be lower in the group that received detailed information, compared to the group that was not informed. Informing patients about anesthetic and surgical procedures in the preoperative period can reduce their perioperative anxiety. In this study; we found that preoperative detailed information in aesthetic nose surgery did not affect the level of postoperative pain, but reduced anxiety levels.
