A meeting was conducted with the children and their parents. Information about the content of the research was provided. Consent forms were completed by the children and their parents. Instructions on how to use the virtual reality headset were given to the children and their parents.

Mothers were asked to comfort and caress their children during the preoperative period.

The first 15-20 minutes of the cartoon were shown to the children before the surgery. After watching the cartoon, the children were sent for tonsillectomy and adenoidectomy surgery. The remainder of the cartoon was shown one hour after the surgery once the child had settled in the recovery room.

Before the tonsillectomy and adenoidectomy surgery, immediately after the child returned to the ward post-surgery, and 8 hours after the surgery:

The child's vital signs were recorded. The child's anxiety and pain scores were assessed.

Consent forms were completed by the children and their parents. Mothers were asked to comfort and caress their children.

Before the tonsillectomy and adenoidectomy surgery, immediately after the child returned to the ward post-surgery, and 8 hours after the surgery:

The child's vital signs were recorded. The child's anxiety and pain scores were assessed. The children in the control group were allowed to watch the cartoon via virtual reality (VR) after all data for the research had been collected to ensure ethical equality.

In the study, a 400-gram virtual reality (VR) headset with an anti-reflective lens system was used, compatible with all earphones with screens ranging from 4.5 to 7.0 inches. The virtual reality (VR) headset, which was lightweight enough for children to wear, was supported on three sides to fit securely on the children's heads and was disinfected after each use. For the experimental group, the compartment at the front of the virtual reality (VR) headset was removed. The earphone was placed into the removed compartment, which was then reinserted. Subsequently, the YouTube virtual reality (VR) feature was activated on the phone, making it ready for viewing.

Systolic Blood Pressure (mmHg) Description: Systolic blood pressure levels measured during the perioperative period.

Diastolic blood pressure levels will be measured to assess changes in blood pressure during the perioperative period.

Heart rate will be measured to monitor cardiac activity during the perioperative period.

Body temperature will be measured to observe temperature changes during the perioperative period.

Hemoglobin levels will be measured preoperatively and within 24 hours postoperatively to evaluate changes in blood parameters during the perioperative period.

Creatinine levels will be measured preoperatively and within 24 hours postoperatively to monitor renal function during the perioperative period.

Pain Score: The Visual Analog Scale (VAS) was used to measure pain intensity in children during the postoperative period following tonsillectomy and adenoidectomy. The children were assessed using the Visual Analog Scale (VAS) before surgery, immediately after returning to the ward post-surgery, and 8 hours after surgery.The Visual Analog Scale (VAS) ranges from 0 to 10, with 0 indicating no pain and 10 representing the worst possible pain. Higher scores indicate greater pain intensity.

Anxiety Score: The Perioperative Multidimensional Anxiety Scale for Children is a visual analog scale consisting of 5 items, each scored between 0 and 100. The scale was used to measure anxiety levels in children during the perioperative period.
