Introduction: Disadvantages of open reduction of subcondylar fractures include visible facial scars and potential facial nerve damage. Endoscope-assisted procedures have solved these problems, however the anatomical adaptation of osteosynthesis plates to the fractured area is difficult in the limited surgical field. Three-dimensional pre-shaped plates specialized for subcondylar fractures recently became available. They are originally not for endoscope-assisted procedures but it may be useful for endoscopic approach because they are very small and pre-shaped. Case report: This paper presents a case of 43-year-old male patient with subcondylar fracture. The treatment provided was open reduction and internal fixation of a subcondylar fracture with three-dimensional pre-shaped plates via transoral approach under endoscopic visualization. Conclusion: The paper highlights contemporary management of subcondylar fracture to avoid complications associated with open reduction and restore the post-operative functions.
