Design outcomes

Primary

Measure	Time frame	Description
Change in Oral Health-related Quality of Life	14 days	Evaluated by OHIP-14

Secondary

Measure	Time frame	Description
Change in pain	7 days	Postoperative pain was assessed using a Visual Analogue Scale (VAS) ranging from the absence of pain (score 0) to the most severe pain imaginable
Change in Mouth opening	7 days	The distance between the mesio-incisal corners of the upper and lower central incisors was measured with the help of a ruler when the mouth opening was at its maximum.
Operation time	Intraoperative	The total time from the first incision of the operation site to the last suture was measured with the help of a digital stopwatch as the operation time.
Change in facial swelling	7 days	With the technique described by Neupert ; * Angle of mandible-tragus * Angle of mandible-lateral canthus of eye * Mandible corner-nose wing * Angle of mandible oral-commissures * Measurements were made with a tape measure from 5 points, with the mandible corner-pogonion.
