Objective : To evaluat the patterns and characteristics of dentofacial deformities which were diagnosed and underwent surgical corrections in the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Prince of Songkla University.

Materials and methods : The records during an 8 - year period from 1991 - 1998 of 85 consecutive patients with dentofacial deformities were reviewed. The demographic data, clinical diagnosis, surgical procedure and complication were analyzed .

Results : The majority of the patients were female (75%) in the third decade of life (61%). Class III facial skeleton was the most common problem (60%). Class II and I facial skeleton accounted for 29% and 11% respectively. Of the surgical procedures, Le Fort I osteotomy was the most commonly performed (76%) for correction of maxillary deformities, while sagittal split ramus osteotomy was the most frequently performed (85%) for correction of mandibular deformities. Complications found in 15 cases (18%) were considered to be minor.

Discussion and conclusion : The high incidence of Class III facial skeleton may indicate that this deormity is among the most unacceptable to the general population and prompts many patients to seek treatment. This finding was comparable to previous studies. Long-term follow-up to study the result of surgical corrections is needed.
