Filter by:After the description of Le Fort fractures, maxillary osteotomies are used to correct dentofacial deformities. The profile changes on nasolabial region resulting from a Le Fort I osteotomy, also that affects nasal airway. The Subspinal Le Fort I osteotomy (SLFIO) describe to prevent undesirable soft tissue changes. In the literature, too many articles have reported the effectiveness of SLFIO in preventing nasal deformation. However, there is no study to evaluate the nasal volume or septum deviation.
The conventional saw compared with the piezo surgery in BSSO to evaluate cutting time, surgery duration, amount of bleeding. The purpose of this study was to answers following clinical questions: Is ultrasonic bonescalpel effective osteotomy like conventional bur in BSSO? and 2) Does it reduce operative parameter like bleeding, duration, lingual split pattern? 3) Does it reduce postoperative morbidity after BSSO.
Dento-maxillary dysmorphoses are defined as an anomaly in the relative growth of the maxilla and/or mandible. They lead to functional disorders (i.e., disturbances in chewing or oral communication) and aesthetic issues with psychological repercussions on self-esteem, affecting the quality of life of these patients. The multidisciplinary treatment involves orthodontics (duration = 18-24 months), orthognathic surgery involving the maxillary and/or mandibular bone (at 12 months), immediately followed by physiotherapy (duration = 3 months). One main goal after surgery is the recovery of month opening to restore an appropriate orofacial function. Motor imagery (mental rehearsal of a movement without actually moving) is effectively used in athletes and in rehabilitation mainly neurological but so far has not been investigated in maxillofacial rehabilitation. Considering that the effectiveness of rehabilitation is increased when physical and mental practices are combined, this leads to propose this study aiming to investigate whether the addition of motor imagery of the maxillofacial region to maxillofacial physiotherapy (based on a practice of physical therapeutic exercises) modifies the recovery of maximum mouth opening, other ranges of motion, jaw function, and quality of life in patients after orthognathic surgery compared to the addition of a control cognitive task [watching a non-emotional content film or filling out a crossword or Sudoku grid] to maxillofacial physiotherapy.
The correction of maxillomandibular dysmorphoses, responsible for both functional discomfort (lip incompetence, ventilation disorders, periodontal disease) but also aesthetic, calls in particular for genioplasty, of which there are several techniques. One of these chin repositioning techniques, called "Chin Wing", cuts the bone to optimize the functional and aesthetic result. While all genioplasty techniques expose the risk of nerve damage and lack of bone consolidation, these parameters are only rarely addressed in the literature in the specific context of this extensive bone cutting. The objective of this work is to assess the satisfaction of patients who have benefited from chin advancement surgery using the "Chin Wing" technique.
This cross-sectional study explores the influence of various types of maxillomandibular deformities on the nutritional status of individuals. Maxillomandibular deformities, which involve the misalignment of the upper and lower jaws, can significantly affect oral functionality, potentially leading to nutritional deficiencies due to compromised food intake. By analyzing the dietary habits and nutritional health of a diverse group of individuals with these deformities, the study seeks to establish the correlation between the severity of the deformity and the individual's nutritional status. Findings from this research can provide a deeper understanding of the additional health risks that maxillomandibular deformities pose and help in the development of nutritional guidelines specifically tailored for individuals suffering from these conditions.
This study hypotheses that using low medial cut osteotomy BSSO in mandibular setback can be an efficient and effective method to limit the bony segment interferences , decreasing muscles stripping during osteotomy ,decrease condylar torque and so securing preoperative condylar position during BSSO in comparison with using high medial cut BSSO.
This study is set up within the framework of the European Union regulation 2017/745 on medical devices. Its objective is to confirm the performance and safety of the Global D implants (ORTRAUTEK® and MINITEK®) used for orthognathic surgery.
Research studies continues to attempt testing modifications to refine the treatment protocols through computer assisted design or computer-generated surgical Wafer splints, have greatly revolutionized the incorporation of digital imaging and 3D design in Orthognathic surgery. Integrating computer guided technology in orthognathic surgery aims to to simplify workup and reduce surgical errors, eliminate occlusal discrepancy, increase the realignment accuracy of the distal segments according to the preoperative plan. Implementing a waferless technique raised the question of efficiency versus the use of occlusal wafers and whether it has a significant measurable effect on the surgical outcome and objectives. Rationale for conducting this study is to assess the difference between the effect of computer guided waferless technique and computer guided technique with occlusal wafer on accuracy of postoperative occlusion and condylar position. .
The study was approved by the Local Ethics Committee and was conducted in compliance with the World Medical Association Declaration of Helsinki on medical research. A total of 335 patients who underwent oral and maxillofacial reconstruction were recorded from Jan 2014 to Jun 2020. Reconstruction with computer-assisted surgery ( CAS), which included, virtual surgical planning, computer-aided design-computer-aided manufacturing (CAD-CAM) surgical guides/templates and pre-bent plates on 3D printed models. Reasons for tissue defect were oncologic, osteoradionecrosis, trauma and osteoporosis. Patients undergoing dental implant placement and orthognathic surgery were excluded. Finally, 136 patients were selected and the reasons for partial or abandon surgical plan performance were described and analyzed.
Orthognathic surgeries for maxillofacial deformities are commonly performed globally. However, they are associated with significant blood loss which can affect the surgical field and result in blood transfusion and its risks. We aim to review the different hypotensive anaesthetic practices for orthognathic surgeries, and their effects on intraoperative blood loss and transfusion requirements.
