Experience with Anterior Maxillary Osteotomy Techniques: A Prospective Study of 20 Cases.

Abstract

This prospective study aimed at studying the complications associated with different techniques of anterior segmental maxillary osteotomy. The study was conducted on 20 cases diagnosed with anteriorly prognathic maxilla with class 1 molar relation. The patients were followed up for a period of at least 1year. The clinical and demographic data along with the intraoperative and postoperative complications associated with different treatment techniques were recorded. In five cases, Wassmund technique was followed with average time span of 32min. Wunderer and Cupar technique took average time span of 23min. Two patients presented with four non-vital teeth in a follow-up period of 1year and one patient treated with Cupar's technique had complication of palatal tear. Only one patient reported with relapse in a follow-up period and none of the patients had any complication associated with hemorrhage, neurosensory alteration or requiring plate removal. The findings of our study recommend ASMO as treatment modality of choice in patients with bimaxillary and/or dentoalveolar protrusion with Cupar's technique providing more ease of operation.
