NCT ID: NCT06454825 Completed - Clinical trials for Maxillofacial Abnormalities

Effects of Antiemetic Agents in Orthognathic Surgery Patients

Start date: April 14, 2020
Phase: Phase 4
Study type: Interventional

In an effort to prevent or treat consistently high rates of PONV following maxillofacial operations, several medications, techniques and multimodal protocols have been studied. In the present study, the investigators hypothesized that combining metoclopramide with granisetron will improve PONV incidence when compared with granisetrone alone.

Does Subspinal Le Fort I Osteotomy Affect the Nasal Airway Volume

Start date: January 15, 2021
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06273189 Completed - Clinical trials for Maxillofacial Abnormalities

Ultrasonic Bone Scalpel in BSSO

Start date: December 15, 2018
Phase: N/A
Study type: Interventional

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.

Maxillofacial Rehabilitation Using Motor Imagery vs Sham After Orthognathic Surgery

MAXIMAND
Start date: March 1, 2024
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT06183853 Recruiting - Clinical trials for Maxillofacial Abnormalities

Evaluation of the Long-term Results of Extended Supra-basillary Genioplasty of the "Chin Wing" Type Without Bone Graft

SASCWatch
Start date: September 5, 2022
Phase:
Study type: Observational

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.

Impact of Maxillomandibular Deformities on Individuals' Nutritional Status

Start date: July 1, 2023
Phase:
Study type: Observational

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.

NCT ID: NCT05713084 Active, not recruiting - Clinical trials for Maxillofacial Abnormalities

Condylar Position Changes and TMJ Functions After BSSO Mandibular Setback, Low Medial Cut.

Start date: September 28, 2022
Phase: N/A
Study type: Interventional

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.

Study Evaluating the Performance and Safety of Global D Implants Indicated for Orthognathic Surgery

CMF-ORTHO
Start date: February 4, 2022
Phase:
Study type: Observational [Patient Registry]

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.

NCT ID: NCT05151042 Recruiting - Clinical trials for Congenital Abnormalities

Digital Occlusal Wafer Versus Waferless Distal Segment Repositioning for BSSO in Skeletal Mandibular Deformities

Start date: November 15, 2021
Phase: N/A
Study type: Interventional

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. .

NCT ID: NCT04895319 Completed - Clinical trials for Maxillofacial Abnormalities

Adherence to Computer-assisted Maxillofacial Reconstructions

Start date: January 1, 2014
Phase:
Study type: Observational

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.
