Evaluation and refinement of the intraoral vertical subcondylar osteotomy.

Data were collected from the use of intraoral vertical subcondylar osteotomy in 42 patients. The results of treatment compare favorably with those attained with sagittal split osteotomy and extraoral vertical subcondylar osteotomy. Modification in instrumentation and techniques has further improved the intraoral vertical subcondylar osteotomy. The primary advantage of this technique compared to the sagittal split osteotomy is the much less frequent and less severe damage to the mandicular nerve. This intraoral technique deserves serious consideration as the method for reduction of the prognathic mandible.
