Design outcomes

Primary

Measure	Time frame
The primary variable is the amount of pain based on the visual analog system (VAS), which is asked of the patient on a scale of 0 to 10. Timepoint: Days 2 and 7 after surgery. Method of measurement: Use the VAS system to measure pain.;Another primary consequence variable is the amount of swelling, which is measured by measuring the distance from the corner of the eye to the angle of the jaw on the same side and the distance from the ear hole to the corner of the lip on the same side using a ruler or meter. Timepoint: Days 2 and 7 after surgery. Method of measurement: Use a meter or ruler to measure inflation.;Another primary outcome variable is the amount of trismus, which measures the amount of mouth opening using a ruler or meter. Timepoint: Days 2 and 7 after surgery. Method of measurement: Use a meter or ruler to measure the amount of trismus.	—
