<p>This study aimed to report six cases of unilateral condylar hyperplasia (CH), regarding their demographic and clinical characteristics and imaging and histopathological findings. Sex, age, affected side, history of the case, complementary examinations and treatment were recorded. Five cases (83.3%) were females and the mean age of the study population was 19.3 years (range: 14-28 years). The right condyle was affected in 4 cases (66.6%). Five (83.3%) patients were subjected to condylotomy, and high condylectomy was done in 1 (16.6%) case. The patients were followed up postoperatively for a mean period of 27.5 months. All patients received surgical and orthodontic treatment. In the present study, CH occurred more frequently in the first decades of life and it was more prevalent in females. The right condyle was more affected than the left one and condylotomy combined with orthodontics was the main treatment performed.</p>

Objective: The aim of this study was to assess patients subjected to replacement surgery of the pre maxilla with bone graft, having as donor area the iliac crest and chin, and the relation with upper canines erupted in grafted areas. Materials and Methods: 54 records were evaluated from cleft patients that were under treatment at CAIF -Center of Attention to Clefts in Curitiba, PR, Brazil, both sexes, with unilateral and bilateral lip and palate clefts. Patients younger than fourteen years old, both sexes, that lost the surgical segment or did not continue the treatment at same welcoming institution, were excluded. The surgical segment average was 5.72 years. Results: Using both descriptive and chi-square statistics, we observed a statistically significant distinction regarding the eruption of upper canines in the region of secondary bone grafts when using iliac crest and chin grafts, which 62.8% of the sample that was treated with chin grafts happened to have an eruption of upper canines, and 37.2% were successful with iliac crest grafts (value-p 0.028). Conclusions: It is necessary to carry out a study with a larger sample size and where the samples are paired in order to confirm the superiority the iliac crest donor area as the gold standard for this surgical procedure.

Surgically assisted maxillary expansion is a technique used to correct transverse maxillary deficiency, which is a dentofacial anomaly related to the decrease of the upper arch over the lower arch. It is applied to patients in their late teens and adults due to skeletal maturity, causing obliteration of the intermaxillary suture, which requires orthodontic procedure, associated with surgery. The purpose of this study is to report the clinical case of a patient admitted for surgical maxillary expansion through the modified technique and point out the possible advantages, such as aesthetics maintenence, long-term stability, faster return to orthodontic treatment, and improved bone healing. However, there are some contraindications when the patient presents severe crowding, roots of the canine and lateral incisor are converging and in patients who will undergo to protraction with facial mask.
