The effect of subperiosteal tunnel in internal lateral osteotomy on the amount of periorbital edema and ecchymosis and subconjunctival ecchymosis after rhinoplasty

investigate the effect of subperiosteal tunnel in lateral internal osteotomy on periorbital edema and ecchymosis and subconjunctival ecchymosis after rhinoplasty.

For patients on one side of the nose, before the lateral osteotomy, the subperiosteal tunnel will be created by the periosteal elevator, and on the opposite side, the osteotomy will be performed without creating the subperiosteal tunnel and maintaining the periosteal adhesion. In each patient, which side will be osteotomy by which method is chosen randomly. Edema and ecchymosis on the 2nd and 7th days after surgery will be evaluated using the standard 5-grade Gokalan-kara periorbital edema and ecchymosis system by a third surgeon who does not know how to perform the surgery.

Imam Khomeini Hospital in Ahvaz All patients underwent open rhinoplasty, and one side of the nose of the subperiosteal tunnel was created by periosteal elevator, and on the opposite side, without creating a subperiosteal tunnel and maintaining periosteal adhesion, osteotomy was performed, and at the end, a splint was placed on the patient. After the surgery, a new dose of dexamethasone 8 mg is prescribed for all patients

Patients in need of rhinoplasty surgery. Patients with coagulation problems and a family history of bleeding disorders, patients with high blood pressure and patients with a history of taking anticoagulant drugs, Patients with a history of previous rhinoplasty, trauma will be excluded from the study.

In each patient, a subperiosteal tunnel will be created by a periosteal elevator on one side of the nose randomly before the lateral osteotomy, and on the opposite side, the osteotomy will be performed without creating a subperiosteal tunnel and maintaining the adhesion of the periosteum.

edema and ecchymosis

Simple randomization For patients who have a subperiosteal tunnel created on the right side of the nose and the left side has no tunnel, an even number is considered, and for patients who have a subperiosteal tunnel created on the left side of the nose and the right side has no tunnel, an odd number is considered. will be Then we will extract the relevant numbers from the table of random numbers according to the number of the studied sample. Each number is written on a card and placed in an envelope. The envelopes are sealed and the patient's number is written on each envelope. If the number inside the patient envelope is even, the subperiosteal tunnel is created on the right side, and if the patient number is odd, the subperiosteal tunnel is created on the left side.

The evaluators of the outcome after the completion of the surgery did not know about the type and location of the osteotomy
