Active clinical trials for "Maxillofacial Abnormalities"

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. .

This study will use a 3D scanner to print a 3D model or mold for each patient's prosthesis. The goal of this study to provide patients with a new, faster method of imaging and creating prostheses that preserves the quality of the current method while reducing time spent by both the patient and providers. Patients that are eligible will have a non-invasive 3D scanner (Artec Space Spider) to image the indicated areas of their head and face to help create their new prosthesis. Patients will come in for visits as needed to fit and adjust their prosthetic. Additionally, patients will be asked to complete questionnaires and have follow-up visits at certain time -points pre and post prosthetic completion.

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 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 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.

US-guided superficial cervical plexus block (SCPB) may be used for several head and neck surgeries. Local anesthetic is injected under the sternocleidomastoid muscle for SCPB. It has lower complication rate compared to the deep cervical plexus block. Postoperative pain management is important in patients underwent orthognathic surgery. Effective pain treatment provides early mobilization, and shorter hospital stay.

Orthognathic surgery aims to standardize position of the maxilla and the mandible and therefore chewing, breathing, phonation and swallowing functions. In postoperative, several physical and functional consequences are observed in patients: transient edema of the face, maxillo-mandibular blocking (causing difficulties to eat and occasional weight loss), pain and sensory disturbances (labial or/and chin paresthesias). Achieving sessions of manual lymphatic drainage by physiotherapist may allow faster decrease of postoperative edema, improved postoperative comfort and mental well-being. The main objective of this study is to evaluate the efficacy of sessions of manual lymphatic drainage to reduce postoperative edema.

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.

Comparing the pre and post-operative blood plasma levels of vitamin C according to oxidative stress and investigate the correlation between post-operative analgesia requirement and vitamin C levels following orthognathic surgery.

To determine if providing a written document in addition to the standard oral discussion of surgical risks improves risk recall for the parents/guardians of a child seen in consultation for cleft palate surgery, and if this has any effect on overall satisfaction after the procedure
