The aim of this research work was to verify the usefulness of cephalometric analysis in the valuation of patients with obstructive sleep apnea (OSA), comparing the initial study and at the end of the study six months later, after using Karwetzky's repositioning mandibular device, only during sleep. The cephalometric measurements used were those described by Johns, Sandler and Braun to value patient with OSA, of which we took into account the following measures: longitude of the mandibular plane to the hyoids bone, posterior space of airway, longitude of soft palate and lingual height, because they are structures in where changes are observed when using the surgical appliance. Ten patients of both sexes were studied (4 women and 6 men), between 30 to 65 years old, whose an improvement was observed only in three of them after six months of continuous use during the night; in the other patients we verified that results were not satisfactory because surgical appliance was not use as constant as we wanted. The parametric statistical analysis used was Student paired t test. In spite of having few patients in this study, the obtained results were as satisfactory as those described in the literature (decrease of the longitude among the mandibular plane to the hyoids bone, increase of the posterior space of airways, decrease of the longitude of the soft palate and the lingual height), although the sample was not statistically significant. Therefore, we concluded that Karwetzky's mandibular advance device is an option of treatment for patients with light to moderate OSA, provided that patient cooperates, constantly using the repositioning device and following the indications of the specialist.
