Anterior segmental maxillary osteotomy. A 24-month follow-up.

Anterior segmental maxillary osteotomies were performed in 14 patients. Both the downfracture and the Wunderer methods were used. The patients were examined regularly until 24 months after surgery. No major complications occurred. Long-term stability of the osteotomy was found to be acceptable except when used to correct deep overbites. In these cases, other methods should be considered.
