Abstract: (204 Views)
Introduction: Symphysis and parasymphysis fractures have been reported to be associated with mandibular condyle fractures. The aim of this study was to evaluate the relationship of mandibular chin angle, age, gender, and anterior fracture type with the condylar fracture occurrence.
Materials and Methods: This cross-sectional study included 142 patients with symphysis or parasymphysis fracture, conducted at Imam Reza Hospital, Tabriz, Iran (2022–2023). Patients’ CT scans were reviewed and divided into two groups: those with condylar fractures and those without condylar fractures. The mandibular chin angle was measured on CT scout views using ImageJ software. Demographic data were obtained, and statistical analyses were performed (α = 0.05).
Results: The mean ± standard deviation of the chin angle in patients with and without condylar fractures was 129.07 ± 8.68 and 127.03 ± 8.11, respectively, with no statistically significant difference (P = 0.151). The mean ± standard deviation of age in patients with condylar fractures was 27.87 ± 9.20 compared with 27.22 ± 8.41 in those without, which was not statistically significant (P = 0.350). The incidence of condylar fractures was higher in males than in females, but the difference was not statistically significant (P = 0.106). Condylar fracture rates were 52.25% in patients with parasymphysis fractures and 41.94% in those with symphysis fractures, and this difference was not statistically significant (P = 0.310).
Conclusions: None of the evaluated factors were reliable predictors of condylar fracture, highlighting the need for further multicenter studies with larger samples to clarify potential risk factors.
