Résumé

Conservative treatment, including observation and closed treatment, as well as open reduction and internal fixation are existing options for treating condylar process fractures. Extraoral approaches are widely preferred for open reduction and internal fixation. Transoral access for condylar base and neck fractures is not yet commonly used as it is technically demanding and requires special equipment. In this study, the transoral endoscopically assisted approach is described, and its outcomes and complications were investigated. Imaging data and clinical records of 187 patients with condylar process fractures, treated via endoscopically assisted transoral approach between 2007 and 2017 were analyzed. Parameters included diagnosis and fracture classification, treatment, osteosynthesis configuration and postoperative complications. Early complications, including infection, transient postoperative malocclusion, pain and limited mouth opening, occurred in 35 patients (18.7%). Late onset complications, such as screw loosening were documented in only 4 patients (2.1%). Revision surgery following postoperative 3D imaging was required in only 3 cases (1.6%). Fragment length ranged from 15.5 to 38.3 mm. In 57.7% of patients with condylar fragment length < 20 mm, a single osteosynthesis plate was used, with no elevated complication rate. Two osteosynthesis plates with 4 screws each was used as standard in longer fragments. Endoscopically assisted transoral treatment of condylar process fractures is a reliable, yet technical demanding technique. It allows for reduction and fixation of fractures with a condylar fragment length of > 15 mm with low postoperative complication and revision rates.

BACKGROUND BACKGROUND
Conservative treatment, including observation and closed treatment, as well as open reduction and internal fixation are existing options for treating condylar process fractures. Extraoral approaches are widely preferred for open reduction and internal fixation. Transoral access for condylar base and neck fractures is not yet commonly used as it is technically demanding and requires special equipment.
PURPOSE OBJECTIVE
In this study, the transoral endoscopically assisted approach is described, and its outcomes and complications were investigated. Imaging data and clinical records of 187 patients with condylar process fractures, treated via endoscopically assisted transoral approach between 2007 and 2017 were analyzed. Parameters included diagnosis and fracture classification, treatment, osteosynthesis configuration and postoperative complications.
RESULTS RESULTS
Early complications, including infection, transient postoperative malocclusion, pain and limited mouth opening, occurred in 35 patients (18.7%). Late onset complications, such as screw loosening were documented in only 4 patients (2.1%). Revision surgery following postoperative 3D imaging was required in only 3 cases (1.6%). Fragment length ranged from 15.5 to 38.3 mm. In 57.7% of patients with condylar fragment length < 20 mm, a single osteosynthesis plate was used, with no elevated complication rate. Two osteosynthesis plates with 4 screws each was used as standard in longer fragments.
CONCLUSION CONCLUSIONS
Endoscopically assisted transoral treatment of condylar process fractures is a reliable, yet technical demanding technique. It allows for reduction and fixation of fractures with a condylar fragment length of > 15 mm with low postoperative complication and revision rates.
