Purpose:
Extraoral approaches for open reduction and fixation of condylar fractures in children are associated with serious risks of complications, including facial nerve injury, facial scarring, parotid fistula, and auriculotemporal nerve injury. The purpose of this study was to retrospectively evaluate the outcomes of transoral endoscopic-assisted open reduction and internal fixation of condylar fractures and hardware removal in pediatric patients.
Material And Methods:
This study was designed as a retrospective case series. The study included pediatric patients admitted with condylar fractures that were indicated for treatment with open reduction and internal fixation. The patients were clinically and radiographically evaluated with regard to occlusion, mouth opening, lateral and protrusive movement of the mandible, pain, chewing and speech difficulties, and bone healing at the fracture site. Computed tomography images were used to assess the reduction of the fractured segment, the stability of fixation and progress of healing of the condylar fracture at follow-up visits. The same surgical treatment approach was applied to all patients. The data from the study were analyzed for a single group without any comparison to other groups.
Results:
The technique was used for the treatment of 14 condylar fractures in 12 patients between the ages of 3 to 11 years. A total of 28 transoral endoscopic-assisted approaches to the condylar region either for reduction and internal fixation or hardware removal were applied. The mean operating time was 53.1 (±11.3) minutes for the fracture repair and 20 (±2.6) minutes for hardware removal, respectively. The mean follow-up time of the patients was 17.8 (±2.7) months (median: 18) months. All patients regained stable occlusion, satisfactory mandibular motion, stable fixation, and complete bone healing at the fracture site at the end of their follow-up period. There was no transient of permanent facial nerve or trigeminal nerve injury in any of the patients.
Conclusions:
Endoscopically assisted transoral approach is a reliable technique for reduction and internal fixation of condylar fracture and hardware removal in pediatric patients. The serious risks of extraoral approaches including facial nerve injury, facial scar, and parotid fistula can be eliminated by using this technique.
