The aim of this study is to compare the changes in upper airway edema with the preoperative and postoperative ultrasonographic measurements of patients who undergo pobotic prostatectomy in the trendelenburg position. The secondary aim is to investigate the correlation between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.
