Summary

Objective: This study aims to detect changes in blood flow in the mental foramen after surgery compared to before orthognathic surgery. Materials and Methods: This study will include a total of 16 patients, aged between 18-60, who were planned for orthognathic surgery due to malocclusion complaints. Patients will be evaluated clinically and radiologically before surgery, 1 week, 1 month, and 3 months after the surgery. Panoramic radiographs will be taken before surgery and 3 months after surgery, and a fractal analysis of the ROI area determined distal to the mental foramen will be performed. Pain will be scored from 1 to 5 using the Pinprick test before surgery, 1 week, 1 month, and 3 months after surgery, while pressure and neurosensitivity will be scored using VAS. Neurosensory evaluation will be performed using two-point discrimination (dividing the area between the lower lip and chin into 9 regions), and left-right discrimination will be checked using the brush test. Blood flow in the mental foramen will be evaluated using ultrasonography.

Conditions

• Orthognathic Surgery

Interventions

Type	Name	Description
PROCEDURE	orthognathic surgery	Mandibular setback, Maxillary advancement, Bilateral sagital split osteotomy
PROCEDURE	USG examination	Comparison of blood flow in the mental foramen before and 1week, 1 month and 3 month after orthognathic surgery using ultrasound examination
PROCEDURE	Subjective evaluation - Neuro-sensitivity tests	Direction determination, two-point separation, pinprick, and brush tests, along with neurosensitivity VAS and pressure VAS, were applied to the patients. These tests were performed before surgery (T0), seven days after surgery (T1), one month after surgery (T2), and three months after surgery (T3).
