RESUMO
<p><b>OBJECTIVE</b>To investigate one-staged orthognathic surgery and arthroscope-assisted condylar reconstruction with costochondral graft for temporomandibular diseases combined with dental-maxillofacial deformities.</p><p><b>METHODS</b>The preoperative measurement and model surgery was performed. The patients underwent arthroscope assisted condylar reconstruction with costochondral graft combined with bimaxillary surgery or mandibular surgery.</p><p><b>RESULTS</b>From Sept. 2003 to Dec. 2005, 15 cases were treated successfully with no bleeding, nerve injury and infection. The patients were followed up for 29 to 52 months (mean, 31.8 months). The appearance was markedly improved. TMJ function was good with no pain. The average maximum interincisal opening was 33.6 mm.</p><p><b>CONCLUSION</b>Compared with traditional operation, one-staged orthognathic surgery and arthroscope-assisted condylar reconstruction with costochondral graft has its advantages. Indication selection and preoperative design are very important.</p>
