: Mandibular fractures are among the most common facial injuries. Bilateral fractures of the mandibular body region (BBMFs), however, are rare. The aim of this retrospective study was to analyze the characteristics, surgical management, and outcomes of BBMFs in a third-level trauma center in northern Italy. : Between 1 January 2001 and 31 December 2023, the following data were collected about patients hospitalized for BBMFs: age, sex, cause of fracture, dental status, degree of mandibular atrophy, surgical approach, number and thickness of plates used, concomitant maxillofacial fractures, length of hospital stay, and outcomes. Statistical analysis was performed using SPSS software. : During the study period, 26 patients (11 males and 15 females) presented with BBMFs, of which five were dentate (median age, 19 years) and 21 edentulous (median age, 80 years). The primary cause of trauma was road traffic accidents (RTAs) in dentate patients and falls in edentulous patients. In most dentate patients, fractures were treated using an intraoral approach with rigid or mixed fixation, using ≤1.4 mm thick plates. Edentulous patients were primarily treated using an extraoral approach and rigid fixation with ≥1.5 mm plates. The use of plates ≥ 1.5 mm was statistically associated with edentulous patients ( = 0.042) and with increasing degrees of atrophy ( = 0.020). : This study shows that BBMFs are uncommon injuries, associated with high-impact trauma in dentate patients and medium- or low-impact trauma, such as falls, in edentulous patients. Internal fixation was predominantly rigid, with thicker plates used as the degree of mandibular atrophy increased.
下颌骨骨折是最常见的面部损伤之一。然而，下颌体部双侧骨折（BBMFs）却很罕见。本回顾性研究的目的是分析意大利北部一家三级创伤中心中BBMFs的特征、手术治疗方法及治疗效果。：在2001年1月1日至2023年12月31日期间，收集了因BBMFs住院患者的以下数据：年龄、性别、骨折原因、牙齿状况、下颌骨萎缩程度、手术入路、所用钢板的数量和厚度、伴发的颌面骨折、住院时间及治疗效果。使用SPSS软件进行统计分析。：在研究期间，26例患者（11例男性和15例女性）出现BBMFs，其中5例有牙（中位年龄19岁），21例无牙（中位年龄80岁）。有牙患者创伤的主要原因是道路交通事故（RTAs），无牙患者则是跌倒。在大多数有牙患者中，骨折采用口内入路，使用厚度≤1.4 mm的钢板进行坚固或混合固定。无牙患者主要采用口外入路，使用厚度≥1.5 mm的钢板进行坚固固定。使用≥1.5 mm的钢板在统计学上与无牙患者相关（P = 0.042），且与萎缩程度增加相关（P = 0.020）。：本研究表明，BBMFs是罕见的损伤，有牙患者与高冲击力创伤相关，无牙患者与中低冲击力创伤（如跌倒）相关。内固定主要为坚固固定，随着下颌骨萎缩程度增加，使用的钢板更厚。
