Comparison 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

Abstract

Introduction: 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. The main clinical features of zygomatic arch fractures include diplopia, enophthalmos, sub conjunctival ecchymosis, extraocular muscle entrapment, cosmetic deformity with depression of the malar eminence, facial widening, malocclusion and neurosensory disturbances of the infraorbital nerve. Treatment of zygomatic arch fractures varies from observation to open reduction. The Gilles temporal approach has been 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 used a new method: using fifty millimeters needle without surgery cut for replacement of broken zygomatic arch and we compromise the amount of pain, edema, maximum mouth opening and ecchymosis before and after the surgery. Materials and Methods: All patients with isolated zygomatic arch fracture referred to Imam Reza Medical Center, department of maxillofacial surgery during 2019-20 were taken ct scan.the 50 mm needle were used for reduction with 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.
