Ultrasound Guided Trigeminal Nerve Block in Maxillofacial Surgeries

Maxillofacial Injuries

This study aims to evaluate the perioperative analgesic effect of USG Trigeminal Nerve Block in adult patients undergoing maxillofacial surgery. We hypothesized that giving USG-guided TNB in patients undergoing maxilla-facial surgery could reduce the requirements of opioids perioperatively and avoid the side effects of opioids used. The aim of this double-blind study is to evaluate the effect of USG-guided TNB intra- and post-operatively in terms of pain relief, opioid consumption and adverse effects in patients undergoing such elective surgeries.

A Cohort Prospective Study of Predictors Influencing the Quality of Visualization of the Operating...

MalocclusionMaxillofacial Injuries2 more

It is very important to decrease the bleeding during bimaxillary osteotomy in order to increase the visibility of the surgical site. Our primary goal is to investigate the predictive value of pre- and perioperative factors, including controlled hypotension, on visibility of surgical site during bimaxillary osteotomy.

Comparison Between Occlusal Versus Apical Bent Wires in Patients on Erich Arch Bar

Maxillofacial Injuries

Patients with jaw fractures requires placement of Erich arch bar for immobilization of the fractured jaw. However, the usage of Erich arch bar is associated with an increased in the incidence of mucosal trauma and plaque accumulation. Conventionally, the ends of the wires has always been placed apical to the teeth. This study aims to determine if a change in the placement of the wire by directing it to the occlusal direction will reduce the incidence of mucosal trauma, plaque accumulation and if the stability of the Erich arch bar will be affected by this intervention. The patients' teeth will be divided into left and right side and randomized into control side (wires end apically) and interventional side (wires end occlusally)

A Clinical Trial of Locally Made Titanium Miniplate and Screw in Maxillofacial Fractures Management...

Maxillofacial InjuriesMaxillofacial Prosthesis Implantation2 more

The study is a blind randomized clinical study on patients with midface maxillofacial fractures coming to Cipto Mangunkusumo Hospital. The subject is the fracture line who met the inclusion criteria and randomly allocated into the study (locally-made miniplate and screw) and control (BIOMET® miniplate and screw) group through a predetermined randomization list. The healing process is follow up using non-contrast head computed tomography immediately after surgery as a baseline, and 3 months post-op. Afterward, a radiologist consultant as a blinded evaluator will evaluate the score of bone density, and screw loosening, while local tissue reaction after fixation evaluates during the patient's visit outpatient clinic. All scores from points of the evaluation group will be collected and going to statistically evaluated using independent t-test or Mann Whitney test depending on the distribution of the data

Superficial Cervical Plexus Block for Orthognathic Surgery

Maxillofacial InjuriesMaxillofacial Trauma2 more

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.

Immediate Reconstruction and Dental Rehabilitation of Maxillofacial Defects

Maxillofacial Injuries

Immediate reconstruction and dental rehabilitation of maxillofacial ablative defects with patient specific reconstruction plates, dental implants, and immediate load provisional screw-retained prosthesis will improve patient short and long term outcomes and improve patient quality of life. Utilizing current technologic advances, patients undergoing large ablative procedures for benign head and neck pathology can now not only have immediate bone and soft tissue reconstruction, but dental rehabilitation as well. Using virtual surgical planning, patient specific selective laser melded reconstruction plates, and dental implants, a screw-retained provisional dental restoration can be fabricated and placed during a one-stage procedure with minimal to no intra-operative prosthetic work required.

Three-Dimensional Printing of Patient-Specific Titanium Plates in Jaw Surgery: A Pilot Study

Mandibular NeoplasmsMaxillary Neoplasms2 more

Medical titanium plates are routinely used in fixing mobilized bone segments in jaw surgeries. Generally these plates are commercialized with standard construction specifications. Thus they should be repeatedly bended and arched to match the contour of anchored jaw bones before located in place and fastened by screws. To prevent stress fatigue induced by plate bending and improve structural design, we utilized the three-dimensional printing technique and developed a new production procedure in fabricating customized titanium plates according to each patient's specific skeletal contours and dimensions derived from medical imaging data. In general, the three-dimensional printing of customized implants are expected to facilitate surgical operation, reduce application duration and improve precise restoration. Up until now, the application of three-dimensional printing of titanium fixation plates in jaw surgery has been available only at two centers globally. The published preliminary work have proved the prospect of customized titanium plates in promoting mandibular reconstruction surgery and upper maxilla orthognathic surgery though their printed titanium plates looked rather bulky and the sample sizes were small and there is still lack of qualified randomized controlled trials between the printed and the conventional titanium plates. To better benefit from the burgeoning use of three-dimensional printing in health care, it is imperative to conduct a feasibility study in exploring the application of three-dimensional printing of titanium fixation plates in jaw surgery based on our patients. The aim of the study is to conduct a case series study focusing on the feasibility and safety of applying three-dimensional printed titanium plates in jaw reconstruction surgery and orthognathic surgery. The outcome measures include the success rate, potential adverse events and accuracy. A sample size of 48 subjects will be recruited prospectively. Considering the facts that titanium plates are widely used in jaw surgery and our unit is the largest oral and maxillofacial surgery center in Hong Kong, the well-designed customized titanium plate is therefore with great potential benefit for the patients in our population. Furthermore, the well-developed three-dimensional manufacturing protocol could also be applied in other relevant medical areas and push forward the personalized medicine era in the future.

REDucing Unnecessary Computed Tomography Imaging for MaxillOfacial INjury

Maxillofacial InjuriesImage Interpretation3 more

The aim is to prospectively assess the association between clinical parameters and the presence of maxillofacial fractures in trauma patients admitted to the emergency department. Our hypothesis is that a clinical decision aid of critical parameters reduces unnecessary produced CT scans in maxillofacial trauma patients.
