Background: The purpose of this study was to prospectively test the accuracy of computer-aided orthognathic surgery comparing the virtual surgical planning with the three-dimensional (3D) outcome.
Methods: Patients that underwent computer-assisted orthognathic surgery were retrospectively evaluated. The postoperative results were compared with the surgical plan, superimposing the postoperative computed tomography (CT) scan onto the virtual plan. Surface-based superimpositioning of the postoperative CT scan onto the 3D preoperative plan was carried out to visualize the discrepancy between preoperative virtual plan and postoperative 3D CT result.
Results: A total of 17 consecutive patients that underwent two-jaw computer-assisted orthognathic surgery were enrolled in the study.The average linear differences for selected points were <1 mm in 12 patients out of 17. In 5 patients out of 17, the average differences for selected points were <2 mm.
Conclusions: An overall high degree of accuracy between the virtual plan and the postoperative result was found.

This reported case represents the first well-documented mandibular surgical ciliated cyst, following orthognathic surgery consisting of a combination of Le Fort I bimaxillary and sagittal osteotomy concomitantly with genioplasty, reported in a Brazilian patient. A case of 43-year-old female presenting a mandibular surgical ciliated cyst after 16 years of an orthognathic surgery, consisting of a combination of Le Fort I osteotomy and genioplasty, is reported. The cystic lesion was enucleated, and the histopathological analysis showed a cystic cavity lined by pseudostratified columnar respiratory-type epithelium presenting ciliated and mucous cells supported by fibrous connective tissue without inflammation.

Introduction: Orthognathic surgery is a fundamental component of a maxillofacial surgeon's practice. In France, 510 specialists actively practice oral and maxillofacial surgery. In OMFs, despite the existence of evidence-based recommendation that address diagnosis, treatment planning, and operating methods, each surgeon/institution has developed an individual approach towards clinical management.

Objectives: This study aims to identify patterns and to describe the clinical course of delayed adverse tissue responses in patients who underwent orthognathic osteotomy with biodegradable osteofixation.
Patients And Methods: Through a retrospective review of cases between 2013 and 2020, we identified three patients who underwent bimaxillary osteotomy and fixation with unsintered-hydroxyapatite/poly-L lactic acid (u-HA/PLLA) devices, after which they developed delayed inflammation. These lesions were treated with drainage and/or removal of the devices.

As maxillofacial surgery becomes increasingly digitized and the transformative impact of pre-surgical scanning and computer simulation is recognized, this clinical paper presents an algorithm for the selection of interventions in severe congenital oligodontia with Angle class-III malocclusion (OCIII) utilizing such technologies. A complex, multifactorial condition with varying degrees of craniofacial involvement, OCIII is associated with edentulous facial appearance, mandibular prognathism and deep underbite, as well as malocclusion. Our methodology involves the integration of CBCT imaging, intra- and extra- oral scanning, and 3D planning with the assessment of bone volume, number of missing teeth, skeletal discrepancies, and patient compliance in the selection of suitable treatments.
