Filter by: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.
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.
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.
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.
Orthognathic surgery aims to correct jaw position taking into account esthetic and functional criteria (dental occlusion, lip position, breathing...). These surgeries are planned using clinical, radiological and dental cast data. The result of this planning are occlusal splints. Orthognathic surgery had improved in the last decade with 3 dimensions computerized tomography scan (3D CT-Scan) planning and osteosynthesis implants. However the accuracy of the operative results compared to the planned ones has rarely been measured.
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
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.
The present study intends to clarify whether there is positional mandibular stability in patients to be submitted to orthognathic surgery. In case of any instability exists, it is needed to understand if this could be related to a particular type of dentofacial deformity or could have any short-term or long-term influence on outcomes of the orthognathic surgery.
The primary objective of this clinical trial is to assess the influence of orthognathic surgery on facial soft tissue, such as changes (volume, linear, angular) of facial hard and soft tissue, in three dimensions, so enabling the setup of 3D normative value tables.
