N/A Skeletal Deformity of Jaws. Intervention 1: alar cinch suture will be used by classic method and reinsertion cinch. For this purpose, a 33 mm needle with 2-0 Nylon monofilament thread of LINX brand made in India is used. In the classic method: the mucosa and muscle on one side are taken with nylon thread 2_0, then the mucosa and muscle on the opposite side are taken directly without touching the skin of the muscle and mucosa on both sides and pulled together. Intervention 2: Intervention group: alar cinch suture will be used by classic method and reinsertion cinch. For this purpose, a 33 mm needle with 2-0 Nylon monofilament thread of LINX brand made in India is used. In the reinsertion method: mucosa and The muscle on one side of the baselar is taken from inside the mouth and the needle comes out of the skin of the baselar area on one side and enters from the same area, and then the mucus, muscle and skin of the other side are taken in this way and finally The two sides of the base are pulled together and swing in the midline. Yes - There is a plan to make this available What will be shared: Comparison of two techniques (classic & reinsertion cinch suturing) in preventing interalar widening before and six months after maxilla orthognathic surgery (advancement, impaction, advancement and simultaneous impaction) in patients referred to Bo Ali Hospital When: Access period starts 6 months after the results are published To whom: Researchers working in academic and scientific institutions Conditions: There is no other special case Where to obtain: To the faculty research site at www.ris.iau.ac.ir How to obtain: To the faculty research site at www.ris.iau.ac.ir Comments:

Interalar width: The width of the base of the nose is the distance between the most prominent point on both sides of the blade of the nose, the ideal position of which should be 1 mm more than the distance between the two inner cantons of the eyes. Timepoint: Six months after surgery. Method of measurement: Patients are divided into three groups based on the type of Lefort surgery: advancement, impaction, advancement, and simultaneous impaction (17). Then, six months after the surgery, patients are asked to go to Bouali Hospital and the interalar width is re-measured blindly by a specialist assistant. Third party assistant (except surgical team and project manager) is used after intra-surgical operation.
