Treatment of post-traumatic open bite by radiofrequency

An 18-year-old man with a fracture of the mandibular symphysis and both condylar heads was treated by open reduction of the fractured symphysis and closed reduction of the fractures of the condylar heads. As the open-bite was not resolved by the operation, elastic traction was applied for three weeks, but there was no improvement. Finally, we gave radiofrequency treatment to the anterior bellies of the digastric muscle, after which the open-bite disappeared and at the follow-up examinations there was no recurrence.
