摘　　要：Purpose::The main aim is to provide clinical reference for the application of mini suture anchor in the reduction and fixation of displaced temporomandibular joint(TMJ)disc with intracapsular condylar fracture.Methods::From October 2018 to October 2019,21 patients(31 sides)with intracapsular condylar fractures and articular disc displacement from West China Hospital of Stomatology,Sichuan University were included.The selection criteria were:(1)mandibular condylar fractures accompanied by displacement of the TMJ disc,confirmed by clinical examination,CT scan and other auxiliary examinations;(2)indication for surgical treatment;(3)no surgical contraindications;(4)no previous history of surgery in the operative area;(5)no facial nerve injury before the surgery;(6)informed consent to participate in the research program and(7)complete data.Patients without surgical treatment were excluded.The employed patients were followed up at 1,3,6 and 12 months after operation.Outcomes were assessed by success rate of operation,TMJ function and radiological examination results at 3 months after operation.Data were expressed as number and percent and analyzed using SPSS 19.0.Results::All the surgical procedures were completed successfully and all the articular discs were firmly attached to the condyles.The articular disc sufficiently covered the condylar head after the fixation.The fixation remained stable when the mandible was moved in each direction by the surgeons.No complications occurred.The functions of the TMJ were well-recovered postoperatively in most cases.CT scan revealed that the screws were completely embedded in the bone without loosening or displacement.Conclusion::Mini suture anchor can provide satisfactory stabilization for the reduced articular disc and also promote the recovery of TMJ functions.
