Delayed Bleeding of Sphenopalatine Artery as a Complication in Le Fort I Osteotomy.

Rates of severe complications in orthognathic surgery are low, but when they occur they can be fatal. This article reports a case of laceration of the junction of the posterior lateral nasal artery and the sphenopalatine artery, resulting in severe delayed bleeding. Patient undergoes a multiple segment Le Fort I osteotomy with no intraoperative or immediate postoperative complications.

Patient Specific Implants to Solve Structural Facial Asymmetry After Orthognathic Surgery.

Facial asymmetry is a challenge for surgeons. Some surgical strategies could be used involved soft or hard tissue of the face. The aim of this report is to show the use of patient specific implants (PSI) in a puzzle strategy based on computer aided design/computer aided manufacturer to solve a complex structural facial asymmetry after orthognathic surgery.

Mandibular Angle Contouring Using Porous Polyethylene Stock or PEEK-based Patient Specific Implants. A Critical Analysis.

Contour augmentation and mandibular angle modification surgery is becoming increasingly. The aim of this research is to compare technique and outcomes in augmentations done with standard implants or PEEK-based patient specific implants (PSI) in mandibular angle. Data from surgical planning, operative and post-operative of 6 months follow-up were revised for 21 patients who were submitted to facial surgery using a stock implant obtained from companies currently on the market or 3D implants created with CAD/CAM technology using PEEK 3D printing.

Patient-specific Implant for Temporomandibular Joint Replacement in Juvenile Arthritis and Facial Asymmetry.

The aim of this report is to present a patient with juvenile arthritis, condylar resorption, and residual facial asymmetry treated with orthognathic surgery and unilateral joint replacement with a full three-dimensional computer-aided design and computer-aided manufacture (CAD-CAM) temporomandibular joint (TMJ) prosthesis, including an increase in the left ramus and mandibular angle to achieve facial symmetry. The patient, a 30-year-old male, came to our department for orthosurgical treatment. The patient had been receiving treatment for juvenile arthritis for 15 years; at facial level, he had a chin deviation of 12 mm from the facial midline, maxillary retrusion, and Angle Class III.

Alveolar Cleft Reconstruction Using Morphogenetic Protein (rhBMP-2): A Systematic Review and Meta-Analysis.

Objective: This study aimed to review the existing evidence regarding reconstruction of the alveolar cleft using recombinant human bone morphogenetic protein-2 (rhBMP-2) in terms of bone volume and bone height.

Design: Systematic review and meta-analysis.

Patients—participants: A systematic search was done.

Temporomandibular Joint Ankylosis: Algorithm of Treatment.

Unlabelled: : Temporomandibular joint ankylosis, according to age of onset, causes severe functional and morphological disorders, as well as stunted craniofacial growth and development.The primary goal of treatment is to resolve the functional and morphological disorders.

Method: Pre- and posttreatment clinical and cephalometric registries were conducted in 15 patients with temporomandibular joint ankylosis over a 10-year period (2002-2012).

Indications of Free Grafts in Mandibular Reconstruction, after Removing Benign Tumors: Treatment Algorithm.

Background: Mandibular reconstruction has been the subject of much debate and research in the fields of maxillofacial surgery and head and neck surgery.

Materials And Methods: A retrospective observational study was undertaken with 14 patients diagnosed with benign tumorous pathologies and who underwent immediate mandibular resection and reconstruction at the Hospital del Salvador Maxillofacial Surgery Unit and Dr. Rodrigo Fariña's private clinic between the years 2002 and 2012.

Orthognathic surgery in craniofacial microsomia: treatment algorithm.

Craniofacial microsomia is a broad term that covers a variety of craniofacial malformation conditions that are caused by alterations in the derivatives of the first and second pharyngeal arches. In general terms, diverse therapeutic alternatives are proposed according to the growth stage and the severity of the alteration. When craniofacial growth has concluded, conventional orthognathic surgery (Le Fort I osteotomy, bilateral sagittal split osteotomy, and genioplasty) provides good alternatives for MI and MIIA type cases.

Osteonecrosis of the jaw in patient with denosumab therapy.

Osteonecrosis (ON) of the jaw has previously been linked to the use of biphosphonates; however, new drugs, also shown similar conditions. This article presents a female patient with mandibular ON related to the use of denosumab. The 55-year-old presented with bone exposure with 8 months of evolution after a dental extraction.

TMJ function after partial condylectomy in active mandibular condylar hyperplasia.

Condylar hyperplasia is a frequent pathology that causes severe facial asymmetries. The partial condylectomy generally halts the disease. The aim of this research was to examine post-condylectomy TMJ function; 14 patients were included in this study, 6 male and 8 female.

[Relationship Between Condylar Size and Transverse Facial Asymmetry in Subject with Condylar Hyperplasia].

Facial asymmetry is a functional and esthetic pathology that can be related to condylar hyperplasia; the aim of this research was to asses the condylar size in the facial asymmetry. Twelve subjects was studies with cone beam computed tomography; the analysis was realized in the software Pax Zenith, Vatech (Korea 2011), using 90 kV and 120 mA and was realized anterior-posterior measurement, superior and inferior measurement and medial-lateral measurement of condylar head and was realized the relations with condylar position with the medial facial line and the position of facial point between superior central incisior, inferior central incisior and chin. The results show that the chin was displaced 6.
