A new method of intra-oral open reduction using a screw applied through the mandibular crest of condylar fractures.

As a result of dry skull morphometry on 50 mandibles, the author has obtained evidence that the mandibular crest, the protuberance between the retromolar trigone and the condylar process, was the thickest portion of the ascending ramus of the mandible. This anatomical structure is available for osteosynthesis of condylar fractures when an appropriate surgical procedure is developed and applied. In this paper, a new intra-oral approach technique is presented which is devised for osteosynthesis of condylar fractures using a cancellous bone screw primarily applied through the mandibular crest.
