CLINICAL STUDY OF THE AMOUNT OF PAIN, EDEMA, AND MAXIMUM MOUTH OPENING BEFORE AND AFTER THE BROKEN ZYGOMATIC ARCH REDUCTION BY NEW METHOD OF USING FIFTY MM NEEDLE WITHOUT SURGERY CUT

The zygomatic arch is the most prominent portion of the face and is commonly
injured during facial trauma. It articulates with the frontal bone, temporal bone, maxilla, and sphenoid
bone, and serves as the main bridge amongst these bones. Isolated arch fractures comprise 10% of all
zygomatic fractures and 5% of all facial bone fractures. Treatment of zygomatic arch fractures varies
from observation to open reduction. The Gilles temporal approach is a commonly used surgical
technique for the reduction of zygomatic arch fractures. However, this surgical approach is associated
with a facial scar in the hairline and risks of facial nerve palsy. In this research, we performed a new
method using a fifty millimeter needle without surgery cut for replacement of broken zygomatic arch
and evaluated the amount of pain, edema, maximum mouth opening, and ecchymosis before and after
the surgery.
Materials & Methods: CT scans were taken of all the patients with isolated zygomatic arch fracture
who were referred to Imam Reza Medical Center and department of maxillofacial surgery during 2019-
20. The 50 mm needle was used for reduction with the new method.
Results: This study was performed on 7 patients with isolated fractures of zygomatic bone. The mean
age of patients was 33.85. 5.87 years. Significant reduction in pain was reported during 7 days after
surgery, but the rate of edema (p = 0.539) and the amount of mouth opening after surgery did not show
a significant difference.
Conclusion: In reviewing the above studies and comparing them with the present study, it was observed
that in simple fractures, the surgical method of the present study was a very useful and uncomplicated
method in patients. Despite open reduction methods, these methods have a lower scar rate, the duration
of surgery is reduced, and this can lead to faster recovery of the patient
