Abstract:
Objective:To evaluate the improvement in the outcome of intracapsular condylar fractures(ICFs)treatment with pre-cise soft tissue reduction in combination with open reduction and internal fixation(PSTR-ORIF)by comparson with traditional open reduction and internal fixation(T-ORIF).Methods:40 patients with ICFs were treated by T-ORIF and PSTR-ORIF(n=20)re-spectively.Preoperative and 6-month postoperative whole-mouth panoramic tomography,CT and MRI imaging data were analyzed,the repositioning of the soft and hard tissues of temporomandibular joints(TMJs),the Helkimo index,clinical symptoms and subjec-tive symptoms were compared between the 2 groups.Results:In PSTR-ORIF(26 sides)and T-ORIF(27 sides)groups,the rate of complete anatomical restoration of fractured segments at 6 months after surgery was 96.15％and 81.48％,and the overall effective rate of ICF articular disc restoration was 96.15％and 74.07％respectively,the height of the ascending mandibular branch was bet-ter restored in patients with B-type fracture after surgery(P＜0.05).At 6 months postoperatively,patients in the PSTR-ORIF group showed significant improvement in mouth opening,mandibular anterior extension distance,and lateral movement compared with the T-ORIF group(P＜0.05).The Helkimo index showed that the PSTR-ORIF group got a significant improvement in the complaint symptom index score and the clinical symptom index score compared with the T-ORIF group(P＜0.05).Conclusion:PSTR-ORIF is more effective than T-ORIF in the treatment of ICFs for the healing of condylar fractures,restore postoperative TMJ mobility and reduce the postoperative joint discomfort through good repositioning of soft tissues.
