Numerous oral and maxillofacial procedures in dentate patients begin with the fixation of occlusions. While several techniques exist to perform mandibulo-maxillary fixation, many surgeons use arch bars in common practice. In cases of severe craniofacial traumas or jaw malformations, such as temporomandibular joint ankylosis, it may be impossible to use rigid arch bars. This technical note reports on the development of a technique to produce pre-shaped rigid arch bars using 3D printing technology. We take the case of a patient who presents Le Fort 1, Le Fort 2 and Le Fort 3 fractures as well as a central palatine disjunction, an angular mandibular fracture and bilateral zygomatic fractures...

BACKGROUND: Progress in medical branches that has taken place since the first child with Goldenhare syndrome (GS) had been described in 1952 by Maurice Goldenhar, facilitated better understanding of this congenital defect. It also gave new perspectives and the opportunity to achieve satisfactory treatment results, mainly due to development of surgical techniques. DATA SOURCES: Based on the literature and own experience, we discussed the phenotype of presentation of GS, ethiopathogenesis, genetic counselling and treatment with particular emphasis on surgery correction of hemifacial microsomia...

Gorlin-Goltz syndrome (GGS) is a rare genetic syndrome with variable expressivity and autosomal dominant inheritance. The major features of GGS include numerous basal cell carcinomas (BCCs), keratocysts of the jaw, palmar/plantar pits and calcification of the falx cerebri. Authors report the case of a 51-year-old male with a 19-year history of GGS and multiple BCCs of the head and neck. He presented with a large ulcerating lesion on the right side of his face involving cutaneous, subcutaneous and muscular tissues of the temporal and orbital region...

Surgical morbidity from open reduction and internal fixation (ORIF) of maxillary sinus wall fracture often surpasses the benefits of ORIF. Hence, the authors devised transnasal endoscopic-assisted reduction of maxillary sinus wall fracture (TERM) without internal fixation as a minimally invasive surgery for maxillary sinus wall fracture. The purpose of this study was to investigate the feasibility of TERM in cadavers and patients. Six cadavers were dissected to evaluate the feasibility of TERM. In addition, 20 patients with maxillary sinus wall fractures who underwent TERM in a tertiary hospital from August of 2013 to December of 2015 were enrolled in this study...

BACKGROUND: Oronasal/antral communication, loss of teeth and/or tooth-supporting bone, and facial contour deformity may occur as a consequence of maxillectomy for cancer. As a result, speaking, chewing, swallowing, and appearance are variably affected. The restoration is focused on rebuilding the oronasal wall, using either flaps (local or free) for primary closure, either prosthetic obturator. Postoperative radiotherapy surely postpones every dental procedure aimed to set fixed devices, often makes it difficult and risky, even unfeasible...

Dislocation of the mandibular condyle from the glenoid fossa can occur in anterior, posterior, lateral, and superior directions. Posterior, lateral, and superior dislocations are rare. Superolateral dislocation is seldom encountered in clinical practice. It is generally associated with fracture of the anterior or contralateral side of the mandible. The occurrence of superolateral dislocation of the condyle hooked above the zygomatic arch with an associated fracture of the medial pole of the condyle is rare and has been reported only once in the literature...

The mandibular coronoid hyperplasia can be classified as a congenital or development change of the temporomandibular joint. This condition occurs due to a no-neoplasic growth of the coronoid process to the infratemporal fossa. Thus, this part of the bone impacts in the posterior face of the zygomatic bone causing limitation of the mouth opening. The aim of this paper is to report a clinical case of a 43-year-old male with mouth-opening limitation 28 years ago. After clinical and computed tomographic examinations, he was diagnosed with bilateral mandibular coronoid hyperplasia...

OBJECTIVE: Surgical safety and efficiency during an OZ osteotomy rely on thorough knowledge of the surgical anatomy of the facial nerve. Although the anatomy of the facial nerve and its relation to the pterional craniotomy are described, a thorough assessment of facial nerve preservation techniques during the OZ approach and its variations is lacking. We assessed the surgical anatomy of the facial nerve related to the OZ and provided a thorough stepwise description on how to preserve it...

Palatal expansion has several orthodontic and orthopedic applications, such as increasing maxillary transverse dimensions and correcting maxillary atresia, oral breathing, and skeletal cross-bites. Little is known about the strain to which craniofacial bones are submitted when a palatal expander is loaded. The objectives of the present work were to propose a new palatal bone-borne titanium device (expansion screw), to determine patterns of strain distribution in craniofacial bones during palatal expansion and to show the clinical results of a new palatal expander supported by implants...

PURPOSE OF REVIEW: To review recent literature pertaining to the use of masseteric-facial nerve neurorrhaphy (MFNN) for facial reanimation in patients with facial paralysis. RECENT FINDINGS: First, MFNN effectively restores some midface tone and function, including the ability to smile. Second, use of the masseteric nerve minimizes synkinesis, dysarthria, and dysphagia that frequently occur after hypoglossal-facial nerve neurorrhaphy. Third, concurrent cable grafting to the zygomatic branch from an intact proximal facial nerve remnant - when available - can restore dynamic eye closure...

Food cravings are common experiences that precede dysfunctional eating behaviors, such as overeating and binge eating. These cravings are often related to negative affect, especially in emotional eaters. Recent studies have revived interest in a theory on the implicit modulation of affect: the facial feedback-hypothesis. This theory claims that mimic expressions influence affective experiences. Given the association between negative affect and food craving, facial feedback could provide a means to reduce or prevent food cravings...
