Postoperative Complications after Surgical Management of Mandibular Angle Fracture
Keywords:Mandibular fracture, surgical management, nerve injury, infection
Introductions: Mandibular angle fractures represent a high percentage and an important clinical challenge because of their treatment pattern and the highest postsurgical complication rate among all mandibular fractures.
Materials and methods: The objectives of this cross-sectional observational study were to observe the postoperative complications after surgical management of a mandibular angle fracture and to facilitate early detection of complications and reduction of patients’ morbidity. This study was carried out among forty patients with mandibular angle fractures who were managed by open reduction and internal fixation by miniplate osteosynthesis. All the study patients were evaluated clinically pre- and postoperatively for various parameters at the 1st week, 2nd week, 1st month, and 4th month. Radiographs (OPG, PA skull, lateral skull, and CT scan of the oral and maxillofacial region) were taken pre- and postoperatively to assess complications. The infection was detected by culture and a sensitivity test. Nerve injury was evaluated by the “tactile test”, the brush directional stroke test by using a ’00’ camel hair brush, and the pinprick test performed by using a sterile 27-gauge syringe needle. Occlusion and chewing were evaluated postoperatively according to the Treatment Scoring System developed by V. Uglesic in 1993. The data was analyzed using the SPSS version 20 statistical software.
Results: In this study, most of the patients (85%) were male and the mean age was 24.5 years. In the fracture line third molar was present in 55% cases. The most common complication of this study shows postoperative nerve injury 30% cases. Infection in 10% cases, malocclusion in 7.5% cases. Slight restricted mouth opening in 5% cases. Other complications such as malunion,, delayed union, and non-union were absent.
Conclusion: The most common complication after surgery is nerve injury along with infection and malocclusion. A careful preoperative assessment, early surgical intervention, meticulous surgical technique, postoperative care and appropriate rehabilitation are the main concern to prevent neurological and other complications.
