BACKGROUND: The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities...

BACKGROUND: Syngnathia is a congenital craniofacial disorder characterized by bony or soft tissue fusion of upper and lower jaws. Previous studies suggested some causative signals, such as Foxc1 or Bmp4, cause the disruption of maxillomandibular identity, but their location and the interactive signals involved remain unexplored. We thus wanted to examine the embryonic origin of syngnathia based on the assumption that it may be located at the separation between the maxillary and mandibular processes...

Multilevel surgery has been established as the mainstay of treatment for the surgical management of obstructive sleep apnea (OSA). Combined with uvulopalatopharyngoplasty, tongue-base surgeries, including the genioglossus advancement (GA), sliding genioplasty, and hyoid myotomy and suspension, have been developed to target hypopharyngeal obstruction. Total airway surgery consisting of maxillomandibular advancement (MMA) with/without GA has shown significant success. Skeletal procedures for OSA with or without a palatal procedure is a proven technique for relieving airway obstruction during sleep...

An implant-supported fixed dental prosthesis is one of the treatment options for an individual with a completely edentulous maxilla. However, a screw-retained or cemented prosthesis can make oral hygiene difficult, especially for patients with a history of periodontal disease or disabilities. Compared with maxillary fixed dental prostheses, implant-supported overdentures offer similar retention and function and facilitate esthetics, phonetics, and hygiene. This report describes the prosthetic rehabilitation of a patient with an edentulous maxilla and a severe maxillomandibular discrepancy that involved the use of a novel prefabricated telescopic system to retain an implant-supported removable dental prosthesis...

Obstructive sleep apnea represents a large burden of disease to the general population and may compromise patient quality of life; workplace and automotive safety; and metabolic, cardiovascular, and neurocognitive health. The disease is characterized by repetitive cycles of upper airway collapse resulting from a lack of pharyngeal airway structural support and loss of muscle tone among upper airway dilators. Polysomnography serves as the gold standard for diagnosis of obstructive sleep apnea and the apnea-hypopnea index is the most commonly used metric for quantifying disease severity...

Maxillomandibular advancement (MMA) surgery, which is the most effective treatment modality for patients with moderate-to-severe obstructive sleep apnea with apparent skeletal discrepancies, has been modified in conjunction with segmental osteotomies, counterclockwise rotation of maxillomandibular complex, and other adjunctive procedures. However, any single type of MMA could not treat or cure all the patients with obstructive sleep apnea showing different dentofacial and pharyngeal patterns. We aimed to suggest critical decision factors for the selective application of MMA subtypes, categorized as straight MMA with genioplasty, rotational MMA, segmental MMA, and segmental-rotational MMA, in the surgical treatment objective process: anteroposterior position of maxilla, upper lip projection, overjet, lower incisor inclination as sagittal factors, and upper incisor exposure and occlusal plane angle as vertical factors...

BACKGROUND AND AIMS: Airway management in anaesthesia for maxillofacial surgical procedures is tricky at times when the nasal/oral routes are contraindicated or are impossible. Tracheostomy as an alternative inherits its own complications. We present a case series of the submandibular route for tracheal intubation as an alternative. METHODS: The procedure was performed in ten selected adult patients with maxillofacial/mandibular fractures associated with a fracture of skull base or nasal bone...

OBJECTIVE: Various techniques have been employed from time to time to achieve maxillomamdibular fixation. Although arch bars provide an effective and versatile means of maxillomandibular fixation, their use is not without shortcomings. However the introduction of intermaxillary fixation screws (IMF) has eliminated many of these issues of arch bars. The aim of the present study was to compare the advantages and disadvantages of intermaxillary fixation screws over the Erich arch bars in mandibular fractures...

Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlusion and function with the long-term objective of bony union. Indirect fixation techniques commonly used for stabilization of caudal mandibular and temporomandibular joint fracture/luxation include maxillomandibular fixation (MMF) with acrylic composite, interarcade wiring, tape muzzles, and the bignathic encircling and retaining device (BEARD) technique...

Accurate repositioning of the maxillary and mandibular segment is essential to improve esthetics and function in orthognathic surgery. With the improvement of three-dimensional imaging technology and computer-aided design and manufacturing techniques, various computer-aided design and manufacturing templates have been developed as alternatives to the traditional error-prone and time-consuming intermediate splint. However, the majority of previously developed templates still use an intermediate splint or the structures connected to occlusal surface and transferred the preoperative virtual plan to the real operation field indirectly...

The present article reports the treatment of a 7-year-old girl with maxillary hypoplasia associated with multiple tooth agenesis through maxillary protraction with skeletal anchorage and pterygomaxillary separation. Two titanium mini-plates were placed in the lateral region of the nasal cavity and used as anchorage for maxillary protraction with a reverse-pull facemask. Pterygomaxillary separation was also performed to enhance the effects of maxillary protraction. One week after surgery, 300 g of force was applied on each side to protract the maxilla...
