BACKGROUND: Cherubism is an autosomal dominant syndrome characterized by excessive bilateral maxillomandibular bony degeneration and fibrous tissue hyperplasia. Conservative management is the preferred treatment as cherubism has a self-limiting course. Functional or emotional disturbances may, however, demand surgical intervention. We report a patient who underwent surgical intervention. Method/Description: He had significant enlargement of lower cheeks and bilateral lower lid scleral show...

Klippel-Feil syndrome (KFS) is classically characterized by fusion of any of the two of seven cervical vertebrae. It is identified by the presence of a triad of clinical signs including short neck, limitation of head and neck movements and low posterior hairline. Unusual bony malformations leading to facial asymmetry is the most common oral manifestation associated with KFS. Such maxillomandibular fusion can also result in restricted mouth opening in children. It's a challenge to provide complete rehabilitation in such children...

Prosthodontic oral rehabilitation procedures are time consuming and require efforts to maintain the confirmed maxillomandibular relationship. Several occlusal registrations and impressions are needed, and cross-mounting is performed to transfer the diagnostic wax-up to master working casts. The introduction of a digital workflow protocol reduces steps in the required process, and occlusal registrations with less deformation are used. The outcome is a maintained maxillomandibular position that is accurately and conveniently transferred...

Various methods have been described to establish maxillomandibular fixation in the treatment of fractures of atrophic, edentulous mandibles. We used the Synthes MatrixWAVE™ system (DePuy Synthes) in combination with dentures in two patients with fractured, edentulous, atrophic mandibles. Fixation was maintained for fractures that were not amenable to, or did not require, open reduction and internal fixation, and the mandibles were both well-healed and had good function at the end of treatment.

PURPOSE: The effects of noncontinuous positive airway pressure (non-CPAP) therapies on the airflow in the upper airway in obstructive sleep apnea (OSA) patients are not completely clear yet. Therefore, the primary aim of this systematic review was to determine the effects of various non-CPAP therapies on the aerodynamic characteristics of the upper airway in OSA patients. MATERIALS AND METHODS: A PICO (population or patient, intervention, comparison, outcome) search strategy, focusing on the effects of various non-CPAP therapies on the aerodynamic characteristics of the upper airway (ie, velocity, wall shear stress, wall static pressure, airway resistance, pressure drop, and pressure effort) of OSA patients, was conducted in the following databases: MEDLINE (PubMed), Embase (Excerpta Medica), and Web of Science...

This article describes 2 patients with complex facial asymmetry characterized by hemiarhinia, microorbitism, palpebral fissure shortening, ipsilateral canthal dystopia, maxillomandibular hypoplasia, and occlusal plane inclination. These unusual phenotypes are part of the oculoauriculo-vertebral spectrum. Their devastating functional, esthetic, and psychologic effects demand the use of different craniofacial surgery techniques, in order to alleviate the profound impact of these pathologies. Initial skeletal balance through bimaxillary distraction osteogenesis and orbital expansion sets the basis for further reconstruction of the nose and periorbital area with local tissue...

Congenital maxillomandibular fusion is a rare disorder of the craniofacial region. Maintenance of the airway and difficulty in feeding are the main concerns for such patients. We performed a PubMed search to identify reported cases of syngnathia. With reference to the site of fusion and corresponding anomalies, the available studies were reviewed. The maxillomandibular fusion can be anterior fusion, unilateral or bilateral fusion, and complete fusion. The condition can be an isolated problem or associated with a syndrome...

Patients with considerable maxillomandibular anteroposterior discrepancies and maxillary hypoplasia require corrective treatment through orthognathic surgery. However, in the treatment of severe maxillary retrognathism, it is necessary to reconstruct areas of bone deficiency through grafting techniques in addition to maxillary advancement using only the Le Fort I osteotomy. Treatment in these patients is more challenging and requires high surgical predictability. Alloplastic materials often have been used for the reconstruction of poor bone contours...

The surgical management of edentulous mandible fractures presents unique challenges secondary to poor bone stock and the absence of dentition to assist with fracture reduction. In complex injury patterns, such as bilateral edentulous mandible fractures, an external approach is often necessary to achieve adequate reduction and adaptation of a load-bearing reconstruction plate. We report a case in which computer-assisted design/computer-assisted manufacturing (CAD/CAM) was applied as an adjunct for the acute management of bilateral edentulous mandible fractures in a 58-year-old man...
