Abstract
The aim of the present work was to compare endoscopic assisted open reduction and rigid fixation with the conventional extraoral approaches in terms of major surgical complications including, risk of facial nerve injury as well as patient satisfactory outcomes in terms of early recovery and function.
The current study included 12 patients suffered from mandibular traumatic injuries that were diagnosed as unilateral condylar fractures either isolated or accompanied with another mandibular fracture. Patients treated by ORIF either through retromandibular incision {group I} or endoscopic assisted transoral approach {group II}. Patient’s age ranged from 18 to 43 years with mean age 27.5 years. Eleven from twelve patients were males (91.7%). Nine patients were from Alminia governorate, eight of them were from cities of the province and only one patient from the provincial capital. The remained three patients were from Cairo, the capital of Egypt. Road Traffic Accident (RTA) was the trauma etiology of nine injuries (75%), while interpersonal violence, fall from heights and work accidents were the etiology of the remained traumatic injuries.
Patients were operated under GA anesthesia. Patients were evaluated clinically at 24, 72 hrs, 1, 2 weeks, 1, 3 and 6 months in terms of postoperative edema, pain, facial nerve integrity, dental occlusion, TMJ functions and post-operative scars. Patients also evaluated radiographically by immediate post operatively panoramic view and CT scan at the completion of follow up period.
The clinical results showed moderate post-surgery edema and pain similarly in both groups. Dental occlusion and TMJ functions returned to normal about 3 months post operatively. Facial scars were considerable in patients treated using retromandibular approach while patients of endoscopic group exhibited almost completely hidden scars. Radiographically the fractured condyles appeared anatomically reduced in the panoramic view and CT cuts. The ramus height of the repaired side was comparable to that of the non-affected side. The condylar angles of the repaired rami did not differ significantly than those of the normal sides. The radiographic findings indicated that the fractured mandibular condyles were reduced appropriately through both techniques.
from the current study we can conclude that, there are comparable results between using EAORIF and CORIF in the treatment of extracapsular condylar fractures with the least risk of facial nerve injury and minimal scar in favor of EAORIF.
