It was observed that the counterclockwise rotation of the maxillomandibular complex produces stable results in patients with long-face pattern undergoing orthognathic surgery.
The present study aimed to establish the profile of patients who underwent orthognathic surgery in a private clinic by evaluating their demographic characteristics, their facial types, and aspects related to the surgical procedures that were performed. The sample consisted of 419 medical records from male and female patients aged 15 to 62 years who underwent orthognathic surgery between 2001 and 2011. A single examiner collected data by evaluating a database of information extracted from medical records, particularly radiographic and photographic analyses. The following criteria were evaluated: gender, age, skin color, type of orthognathic surgery, type of associated temporomandibular joint (TMJ) surgery, complications, and recurrences. Seventeen patients were rejected because they had incomplete records. The average age of the patients was 28.5 years old; most were females (255 patients) and faioderm (295 patients). The most prevalent facial pattern was Pattern III (n = 166, 41.3%). Orthognathic surgery that affected the maxilla, jaw, and chin was the most prevalent type (n = 199, 49.5% of cases). A genioplasty was performed concurrently with combined surgeries and single-jaw surgery in 76.86% of patients (n = 309). TMJ surgery was performed concomitantly with orthognathic surgery in 4% of cases (n = 16). The most common postoperative complication was infection/inflammation (n = 12). We concluded that there was a higher frequency of orthognathic surgery among women and young people, the brunette skin phenotype was prevalent, and most patients had a combination of maxillary and mandibular problems.
Introduction: to compare the condyle morphology of individuals with hyperdivergent skeletal patterns in class ii and class iii skeletal patterns. Methods: multislice computed tomography examinations of 41 individuals (82 temporomandibular joints), aged 18 to 42, with an accentuated vertical growth pattern, of whom 21 had a class ii skeletal pattern and 20, a class iii skeletal pattern were evaluated retrospectively. The following measurements were taken: width (d1), thickness (d2), horizontal angle (a1), and anterior angle (a2) of the condyle. The normality of data distribution was verified by means of descriptive statistics, graphical analysis, and the shapiro-wilk test. The student’s-t test was used to compare the measurements between the groups tested. The pearson correlation was used to identify correlations among quantitative measurements. A 5% level of significance was used for all tests. Results: there was statistically significant difference between groups for the four measurements analyzed (p 0.05). D1 and d2 values were lower for hyperdivergent individuals with a class ii skeletal pattern. A1 was higher for hyperdivergent individuals with a class ii skeletal pattern, and a2, higher for hyperdivergent individuals with a class iii skeletal pattern. Conclusions: hyperdivergent individuals with a class ii pattern have a condyle with a smaller thickness and width, than individuals with a class iii pattern, and these characteristics should be considered when planning the orthodontic and orthognathic treatments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
