SCARIOT, Rafaela et al. Epidemiological analysis of orthognathic surgery in a hospital in Curitiba, Brazil: Review of 195 cases. Rev Esp Cirug Oral y Maxilofac [online]. 2010, vol.32, n.4, pp.147-151. ISSN 2173-9161.

Objective: The present retrospective study explored the spectrum and characteristics of patients treated with orthognathic surgery at the Universidade Federal do Paraná, Brazil. Materials and method: Over a six-year period from July 2002 to July 2008, the records of 195 patients with dentofacial deformities who underwent orthognathic surgical procedures were followed up. Results: Mean patient age was 25.87 years (range 14 to 65 years) and the female to male ratio was 1.5:1. The predominant racial group was "white". Most patients belonged to the economically productive population. Sixty-two patients had complete dentition. Only 3.59% patients had local anesthesia (rapid palatal expansion). Transverse maxillary deficiency was the most common deformity, followed by maxillary anteroposterior deficiency associated with mandibular anteroposterior excess. Mandibular set-back was the intervention most frequently performed. The surgical procedures took an average of 3 hours 51 minutes and orthodontic treatments took an average of 44.48 months. Complications occurred in 22.57% of patients, the most common of which were permanent paresthesia of the lower lip (7.17%) and inadequate fracture reduction (5.12%). Conclusions: The findings included concepts that were useful for characterizing the profile of patients who undergo orthognathic surgery in southern Brazil. The results also may help to correctly develop protocols for patient care designed to improve the overall results of the procedures.
