Maxillary setback of patients with protruded maxilla is a complex procedure. This complexity is aggravated when combined with thalassemia. The Aim of this case report was to treat a beta-thalassemia major girl with severe maxillary protrusion. A 16 year-old beta-thalassemia major girl presented with excessive maxilla, incompetent lips and an everted upper lip was referred for treatment. She had her spleen removed at the age of 9 and her blood transfusion was stopped 3 month before referral. After leveling and aligning with 018 standard edgewise system the patient was sent for Lefort 1 osteotomy. Segmental osteotomy was denied due to excessive bleeding in the procedure. The results showed that the thalassemic patient was effectively treated with presurgical orthodontics, Lefort 1 osteotomy followed by post surgical orthodontics. Very satisfactory esthetic results were obtained in the patient after 4.5 years of active treatment.

Background: To analyze the biomechanical and functional characteristics of different maxillary fixation techniques after Le Fort I osteotomy and occlusal plane rotation, using the finite element method to simulate the mechanical behavior of three different osteosynthesis approaches.
Material And Methods: This is a virtual experimental study carried out using finite element analysis to compare three different osteosynthesis techniques after Le Fort I osteotomy and rotation of the maxillary occlusal plane. Three configurations were tested: four-point fixation with "L" plates (C1), two-point fixation with "L" plates (C2), and two-point fixation with pre-modeled Lindorf plates (C3).

Vertical maxillary excess (VME) is a facial condition characterized by an increased height in the lower third of the face, leading to a longer overall facial appearance. This condition is linked to a significant proportion of malocclusions and is often associated with greater dissatisfaction among patients concerning their appearance. The amalgamation of orthodontics with surgery is a desirable protocol to address VME.

: Orthognathic surgery is used to restore a correct anatomical and functional relationship between the jaws, with postoperative nasal septal deviation (NSD) being a common complication of Le Fort I osteotomy (LF-IO). The aim of this study was to evaluate the occurrence of NSD after LF-IO and to identify possible risk factors. : Pre- and postoperative cone beam computed tomography (CBCT) scans from 2018 to 2023 of 102 patients after LF-IO were analyzed.

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.
