This study evaluates whether adding visual tools to standard preoperative counseling can reduce anxiety in patients scheduled for bimaxillary orthognathic surgery. Participants aged 18-36 years undergoing elective surgery was randomly assigned to one of three groups: (1) standard verbal information, (2) standard verbal information with a short animation video, (3) standard verbal information with a 3-D anatomical skull model demonstration. Anxiety was assessed using the State-Trait Anxiety Inventory and a visual analog scale at two time points: before the information session and approximately one hour before surgery. The goal is to determine whether visual tools provide additional benefit beyond standard counseling in reducing preoperative anxiety.
