The fibula free flap (FFF) has been a workhorse in maxillofacial reconstruction. High success rates of this technique are reported. However, identifying risk factors for failure and analyzing complications can open the way to better patient care. A retrospective analysis was conducted all FFFs performed over 20-year period at low-volume single tertiary center identify postoperative complications. total 129 were included (122 mandible, 7 maxilla). Complete occurred 12.4% partial 7.8%...

Abstract Condylar resorption is a feared complication of orthognathic surgery. This study investigated condylar in cohort 200 patients allowed for powerful update on incidence and risk factors. 9.5% developed resorption. These had average, 17% volume loss with 3.9 mm ramal height 3.1 posterior mandibular displacement. 2% bilateral Univariable analysis identified younger age, bimaxillary + genioplasty procedure, larger advancements, upward movements the distal segment, higher counterclockwise...

Three-dimensional models of mandibular condyles provide a way for condylar remodeling follow-up. The overall aim was to develop and validate user-friendly workflow cone beam CT (CBCT)-based semi-automatic registration segmentation.A rigid voxel-based (VBR) technique two post-operative CBCT-scans tested. Two modified rami, with or without gonial angle, were investigated as the volume interest registration. Inter- intraoperator reproducibility this tested on 10 rami orthognathic patients by...

Abstract Automatic craniomaxillofacial (CMF) three dimensional (3D) dense phenotyping promises quantification of the complete CMF shape compared to limiting use sparse landmarks in classical phenotyping. This study assesses accuracy and reliability this new approach on human mandible. Classic automatic techniques were applied 30 unaltered 20 operated mandibles. Seven observers indicated 26 anatomical each mandible times. All mandibles subjected rounds using Meshmonk. The toolbox performed...

The sagittal split ramus osteotomy is a key approach for treating dentofacial deformities. Although it delivers excellent results, the believed to induce stress temporomandibular joint. Potential inducers could be classified as intra- and postoperative factors resulting in an inflammatory response molecular cascades, which initiate physiological remodeling. Occasionally, this process exceeds its capacity causes pathological remodeling, through either degenerative joint disease or condylar...

Third molar removal complication rates can be as high 30%. Risk assessment tools may lower these rates. Artificial intelligence (AI) driven prediction models are a promising approach to predict possible unfavourable outcomes and cone beam computed tomography imaging play an important role. AI showing excellent results in research settings. To implemented clinical practice they will need overcome some robustness, security, liability, practical issues. If do, integrated electronic patient...

Arthroscopy is a minimally invasive diagnostic tool and treatment strategy in patients suffering from temporomandibular disorders (TMD) when conservative fails. This study aimed to find specific variables on pre-operative MRI or during arthroscopy that could predict success of arthroscopic lysis lavage.This retrospective analysis compared maximum interincisal opening (MIO), pain main complaint (pain, limited MIO joint sounds) with results at short-term medium-term follow-up (ST MT...

Chondrocalcinosis is a non-infectious, inflammatory arthropathy which typically characterized by intra-articular deposition of calcium pyrophosphate dihydrate crystals. The occurrence chondrocalcinosis in the temporomandibular joint uncommon. This report describes case 51-year-old female with periarticular left joint. Disease progression and prolonged complaints pain limitation mouth opening were indications for surgical treatment. placement an alloprosthesis was performed simultaneously...

A sample 151 adult dry (302 CPs) acquired. Three distances were measured, which included width, height, length CP. surface area measurements involved A: above width distance line; B: between incisura mandibulae-Alveolar ridge line C: lines height. Finally, angulations CP gonial angles identified. Both + B acted as...

Several surgical techniques are known to repair defects of the mandible after broad continuity resections due oral cancers. The combined use free vascularised bone grafts and patient-specific plates has proven lead optimal functional aesthetic results. Yet, donor site morbidity local mandibular complications suggest need for ideal patients. Unfortunately, patients with a high comorbidity frequent in population cancers which makes it appropriate think about less complex types reconstruction...

Orthodontic-surgical considerations of dental and bone corrections in cleft Cleft lip palate is a collective term for heterogeneous group congenital abnormalities at the level lips mouth. It most frequent craniofacial disorder subdivided into with or without palate. The condition has major impact on patient’s speech, hearing, appearance, nutritional intake mental stress. Therefore, goal treatment to restore function form ultimately satisfied patient. After primary surgery, closing clefts,...
