The Influence of Gonial Angle on the Incidence of Mandibular Angle Fracture and Evaluation of Treatment Modalities

Author(s): Dalya Abbood* and Waleed Khalil Ismael


Background: Fractures of the mandible are the most common facial fractures, despite considerable collective experience and extensive literature on the subject; some aspects of care still remain controversial. Anatomically there is several regional classifications for fracture sites. Each fracture site has different etiological complex factors according to the force, direction, and the nature of trauma also there are endogenous factors may be had relation with fractures evolving mechanism. This study discusses one factor about the gonial angle measurements and its relation to the fracture site, management work up and possible treatment options. Aims of study: The aims of this prospective study are to analyse the association between the gonial angle measurement and the incidence of mandibular angle fracture radiographically and to evaluate the outcome of different treatment modalities clinically and radiographically. Materials and Methods: Between January 2017 and August 2018, in Al-Yarmuk teaching hospital, the maxillofacial department, (97) patients with fracture mandible were admitted, (36) patients from them had angle fracture. The data for (61) patients were used to compare with included data (Digital precise method were used to measure the mandibular gonial measurement parameter), all data were collected carefully and full history and examination achieved with selective radiological investigation (othropantography) were chosen according to patient data sheet and the outcomes of different treatment modalities were evaluated by using appropriate analytic and statistical Methods and software for representation of the data results. Results: The findings about the relation of the gonial angle measurements to the mandibular angle fracture were significantly remarkable, the mean measurement of gonial angle between patients with angle fracture were (128.3 ± 12.5) which was higher than others non-angled fractures also this result were tested and (P value=0.00728, also impacted 3rd molar tooth among patients is also included and the results was significant, and the high gonial angle measurements (mean=137.6) was significantly positive for selection of the type of managements (open reduction), (p value=0.0359). Conclusions: High gonial angle in early orhtopantography at admission time may be predicted for probable mandibular angle fractures more than others fracture sites also higher angle measures may be predictive factor for advance open reduction surgery. The impacted 3rd molar tooth may be acted as aggravating factors for developing angle fractures.
