    Abstract:
    OBJECTIVE: To evaluate the long-term clinical and radiologic outcomes of treating severely dislocated fractures of condylar neck and base with the comminuted fractures of parasymphysis or mental foramen, specially with crown fracture of deciduous molar and permanent molar or dislocation of the teeth sustained in childhood using bioabsorbable miniplate with open reduction and internal fixation (ORIF). METHODS: Five children (age ranged from 3 to 11 years old averaged 8.2 years; 3 boys and 2 girls) with severely (the condyle dislocated from the glenoid fossa) dislocated fractures of condylar neck or base with the comminuted fractures of parasymphysis or mental foramen, specially with crown fracture of deciduous molar and permanent molar or dislocation of the teeth were treated with ORIF using 1 or 2 bioabsorbable miniplates (through preauricular approach and an oral vestibular approach). All patients have been followed-up clinically and radiographically for a mean of 5.6 years (range, 3-10 years). RESULTS: All patients were cured satisfactorily with excellent occluding relation without restricted mandibular movement, facial asymmetry, retrognathism and ankylosis. 3-10 years follow-up study did not occur any mandibular development disorder. CONCLUSION: The results suggested that ORIF using bioabsorbable miniplate was a reliable fixation technique for use in the treatment of severely dislocated fractures of the condylar neck and base with the comminuted fractures of parasymphysis or mental foramen, specially with crown fracture of deciduous molar and permanent molar or dislocation of the teeth in children when the non-invasive or occlusal therapies were ineffective.
