A 6-Year Epidemiological Study of Mandibular Fractures in Traumatic Patients in North of Iran: Review of 463 Patients

Abstract

BACKGROUND Mandibular fracture is considered the second most common facial fracture worldwide. We aimed to evaluate the epidemiology of mandibular fractures in traumatic patients hospitalized at Velayat Teaching Hospital in Rasht, Iran for 6-year. METHODS In this retrospective study, all traumatic patients with mandibular fractures admitted to Velayat Teaching Hospital, Rasht, northern Iran for 6-year (2013-18) were enrolled. The data collection tool was a checklist consisting of two parts: demographic information, and injury data. All data were collected through the Hospital Information System (HIS), and analyzed using SPSS software and descriptive and analytical statistics tests. RESULTS Overall, 463 hospitalized patients were reviewed. Males had higher frequency than females. The most common accident place was rural roads. The most frequent mechanism of fractures was road accidents. The most common injuries occurred in motorcyclists, followed by car passengers, pedestrians, and cyclists. The highest and lowest frequency of injury occurred in September, and February, respectively. The most common site of fracture was condyle, followed by trunk. In concurrent fractures, the most frequently affected site was maxillary bone, followed by zygomatic bones, orbital, nasal, and frontal bones. CONCLUSION The majority of patients with mandibular fractures were young men of working age following motor vehicle accidents. Consequently, the most effective strategy for reducing accidents leading to mandibular fractures is considering all three components of human, environment, and vehicle.

Correlation of radiomorphometric indices of the mandible and mandibular angle fractures

“…In the present study, 88.98% of patients were males and 11.02% were females, which was in line with other studies [ 2 , 3 , 15 , 33 , 34 ]. Also, the MAF and non-MAF groups were not significantly different regarding gender, which was in line with the findings of Dhara et al.…”

“…The mean age of patients with mandibular fracture in this study was 27.25 ± 9.63 years, which was in line with other studies [ 2 , 3 , 15 , 33 , 34 ]. The two groups of MAF and non-MAF had no significant difference in the mean age, which was similar to the study by Dhara et al.…”

“…The human mandible has an important complex role in facial esthetics, speech, mastication, and deglutition [ 1 , 2 , 3 ]. Mandibular fractures are the second most common fractures in the maxillofacial region after nasal fractures, accounting for 19%–40% of all fractures in this region.…”

Single Versus Two Plate Osteosynthesis for Parasymphysis Fractures of the Mandible: A Prospective Comparative Study

“…Fractures of the mandible occur more frequently than fractures of the other facial bones due to its prominent peripheral position around the lower third of the facial skeleton [5][6][7]. Mandibular fracture management focuses on the early regain of pre-injury form and function with as minimal morbidity as possible [8].…”

“…The mandibular fractures are the most common facial fractures with a high prevalence of condylar and subcondylar fractures of the mandible [1][2][3][4]. In elderly subjects, mandible fractures occur frequently, with an incidence between 27.8% and 43.3% [5,6].…”
