Purpose:
The aim of this survey was to investigate the surgical management of bilateral mandibular angle fracture (BMAF) in Europe.
Methods:
Data were collected from 2008 to 2018 on patients ≥ 16 years of age who underwent open reduction internal fixation (ORIF) for BMAF with a third molar in the fracture line. The study was conducted at 6 European trauma centers. The following data were recorded: sex, age, cause of the fracture, type of fracture (nondisplaced, displaced, comminuted), type of approach (intraoral, transbuccal, or extraoral), thickness of the plate (≤1.4 mm or ≥1.5 mm), number of plates, cause of plate removal, and third molar extraction status.
Results:
25 patients with BMAF (24 males, 1 female, 17 to 83 years old [mean: 28.2 years]) were collected. The main cause of BMAF was assault, and the main surgical approach was intraoral. The most common types of BMAF were displaced + undisplaced (11 patients), displaced + displaced (7 patients), undisplaced + undisplaced (6 patients), and comminuted + comminuted (1 patient). Osteosynthesis was performed with 2 ≤1.4 mm plates on 1 angular fracture and 1 ≤1.4 mm plate on the other fracture in 11 patients, 1 ≤1.4 mm plate on both angular fractures in 6 patients, 1 ≥1.5 mm plate on both fractures in 5 patients, and 2 ≤1.4 mm plates on both fractures in the remaining 3 patients. Out of 25 patients with BMAF, 7 third molars were extracted during ORIF. Among these patients, angular fracture fixation was performed in 3 cases with 1 ≥1.5 mm plate and in 4 patients with 2 ≤1.4 mm plates.
Conclusions:
This retrospective multicenter survey indicates a trend of treating with open reduction and rigid internal fixation at least 1 angular fracture of BMAF and those cases requiring extraction of the third molar in the line of fracture.
