However, this surgery is associated with a risk of recurrence. Osteosynthesis techniques may be the cause of early recurrences. This study aims to demonstrate the efficiency and stability of osteosynthesis with two bicortical screws placed with a transjugal approach. We included patients who benefited from a BSSO alone, between May 2020 and August 2021. We performed the osteosynthesis using two bicortical screws placed with a transjugal approach. All the patients underwent lateral X-rays before the surgery, one week after and minimum six months after the intervention. These medical images allowed to study the mandibular movements during the intervention and the osteosynthesis stability. Twenty-five patients benefited from a BSSO alone. Patients obtained a satisfactory occlusal result. The results showed good stability of the two fragments, after surgery, during the studied period (average follow up of 8 months). Two bicortical screws osteosynthesis placed with a transjugal approach is a simple, effective and stable method for osteosynthesis in case of BSSO.
