In spite of the development of a superior (middle cranial fossa) and posterior (translabyrinthine) approach to the temporal bone, tumours situated in the infralabyrinthine and apical compartments of the pyramid and surrounding base of the skull were still a challenge for neurosurgeons and otologists as well. The infratemporal fossa approach closes the existing gap in the surgical management of ...

Displaced tripod zygomaticomaxillary complex (ZMC) fractures are generally treated with open reduction and 3-point rigid internal fixation at the frontozygomatic suture, zygomaticomaxillary buttress, and inferior orbital rim. However, a clinical dilemma still exists in the postoperative morbidities such as ectropion of the lower eyelid and palpability of the Ti-plate at the inferior orbital rim...

The objective of this study is to analyze the biomechanical effects of sinuses in the skull on the facial impact response. Two models were built, where one had sinuses and the other had none. The models were verified using cadaver test data, including impacts to frontal bone, zygomatic bone, and maxillae. In the maxilla and zygoma impact, sinuses were found to have no significant effect on the ...

PURPOSE A systematic review was performed to find evidence for prophylactic administration of antibiotics in relation to treatment of maxillofacial fractures. METHODS Four studies were retrieved that fulfilled most of the requirements of being randomized controlled clinical trials. RESULTS An analysis of these studies showed a 3-fold decrease in the infection rate of mandibular fractures in...

One hundred Korean adults (50 men, 50 women) were scanned in the upright position using a cone-beam CT (CBCT) scanner. The soft tissue (ST) thicknesses were measured at 31 landmarks, 10 midline and 21 bilateral landmark sites, and the means and standard deviations were obtained for male and female subjects. While 18 of 31 landmarks showed sex differences, the majority showed higher values for m...

Hairline correction surgery is an advanced form of hair transplantation and is performed substantially for Korean females with a flat, broad face and prominent zygoma. However, this procedure demands a considerable learning curve in order to acquire natural results because Koreans have coarse hairs and there is a strong contrast in color between their skin and hair color. As a result, quite a f...

Rehabilitation of maxillofacial defect patients is a challenging task. The most common prosthetic treatment problem with such patients is, getting adequate retention, stability, and support. In cases of large maxillofacial defect, movement of the prosthesis is inevitable. The primary objectives in rehabilitating the maxillofacial defect patients are to restore the function of mastication, deglu...

This paper describes work in progress in the area of planning and prediction of maxillofacial surgery. We focus on true 3D problems which cannot be addressed by conventional 2D cephalometric radiographs. Examples are bilateral repositioning of the zygoma's or treating facial asymmetries. The environment being developed arose from the need of patients for prediction of their expected post-op out...

The loss of midface structures always leads to significant functional and cosmetic deficits, and the reconstruction work remains a challenge for surgeons. We report a rare case with severe midfacial defects involving the maxilla, nasal bone, and zygoma. This patient was treated with a comprehensive approach that included distraction osteogenesis, computer-aided surgery, a fibula bone graft, den...

Intraosseous hemangiomas are benign vascular malformations which are extremely rare in the maxilla, but have been reported in the mandible, zygoma and orbital region. A 12 years old female presented to the oral and maxillofacial department with an ectopically positioned upper left canine in her zygomatic bone and buccal alveolar expansion between the upper left lateral incisor and upper left fi...
