PURPOSE: Reduction malarplasty is one of the most common esthetic surgical procedures performed in the Asian population. Traditional procedures have several complications, such as bone nonunion, malunion, cheek drooping, and damage to the infraorbital nerve and maxillary sinus. Therefore, a more straightforward and effective method of reducing the width of the midface is needed. In this study, we introduce an infracture technique using inward displacement of the zygomatic arch without fixation...

Osteoradionecrosis occurs in 4.74% to 37.5% of patients following radiation therapy for head and neck cancer. Osteoradionecrosis mostly happens in the mandible but seldom occurs in other maxillofacial bones. Here, the authors reported a rare case of zygomatic osteoradionecrosis which occurred after maxillectomy and then radiotherapy because of maxillary myoepithelial carcinoma. After resection of zygoma sequestrum, the defect was repaired with forehead flap and healed uneventfully.

INTRODUCTION: Previous reports indicated that there is geographic and sociodemographic variation in the epidemiology of maxillofacial fractures. Audit of maxillofacial injuries managed at any institution is therefore necessary to understand the trends and proffer strategies for prevention. We therefore embarked on this study to determine the pattern of maxillofacial fractures and concomitant injuries in our institution. METHODS: We carried out a retrospective review of information on demography, aetiology and type of maxillofacial fracture, patients' status, type of crash, level of consciousness and concomitant injuries...

As a surgical approach targeting the pterygopalatine fossa following maxillary cancer due to tumor invasion, Crockett's method is conventional and useful. However, if the tumor is confined to the area between the maxilla and pterygopalatine fossa, it is not necessary to include the zygomatico-orbital in the access osteotomy, and the orbital floor may be preserved. Depending on the range of tumor invasion, the current study reports a more minimally invasive, modified Crockett's surgery that may be considered, which includes resection with modified osteotomy lines and repositioning with fixation of the zygoma and zygomatic arch following maxillary cancer ablation...

Aneurysmal Bone Cyst (ABC) is an uncommon benign lesion affecting mainly the long bones and vertebral column. Its occurrence in the maxillofacial skeleton is rare. So far only five cases of ABC in the zygoma have been reported in the literature. Radiographic features of ABC are not pathognomonic. There can be expansion of bone and it may manifest as cystic lesion with honeycomb or soap bubble appearance. There can be perforation or destruction of cortex of the bone as well. Therefore the differential diagnosis of ABC is quite conflicting with other types of maxillary bone lesions...

Ewing's sarcoma (ES) is an uncommon malignancy, especially in the head and neck region, with only 30 cases reported so far. The mandible is more affected than the maxilla. It represents the most frequent small round cell bone tumor of childhood and adolescence. This report presented a case of 19-year-old male with primary ES in the right side of maxilla, maxillary sinus, zygoma and temporal fossa areas. The clinical, radiographic, histopathologic features and main histopathologic differential diagnosis of ES were reviewed to avoid potential diagnostic pitfalls...

PURPOSE: Intraoperative imaging is gaining widespread use in the management of facial fracture repair. The aim of this study was to determine whether intraoperative imaging changes the management of orbital fracture repair. MATERIALS AND METHODS: A retrospective case series was performed of all cases of orbital fracture repair from 2008 to 2015 in which the intraoperative O-arm was used at Regions Hospital (St Paul, MN), a level I trauma center. The primary outcome variable was a change in management, ranging from orbital plate repositioning to proceeding with orbital floor exploration...

BACKGROUND: Several cadaveric studies demonstrate reliable localization of the transverse sinus and the transverse sigmoid junction (TSJ). These studies use the line drawn from the inion to the posterior root of the zygoma (IZ) and the asterion, respectively. We investigated how the size difference between the right and left transverse sinuses (TS) and sigmoid sinuses (SS) affected the accuracy of their respective superficial landmarks, particularly with regards to where this relationship may result in unsafe and/or complicated surgical access...

BACKGROUND: Various surgical methods have been developed and used to reduce prominent malar bones. The most common reduction malarplasty methods are resection of the bone strip of the malar bone with L-osteotomy or I-osteotomy, followed by setback and fixation. However, these methods could be associated with complications due to the bone strip resection. The present article introduces an effective and safe method that reduces the zygoma without resection of a malar bone strip. METHODS: Through preauricular and intraoral incisions, we performed the current L-osteotomy without resection of the malar bone strip using a reciprocating saw...

BACKGROUND: Zygoma fracture is of clinical importance because malar prominence plays an essential role in facial appearance. Traditionally, most maxillofacial surgeons perform osteosynthesis with titanium plates and screws for rigid fixation. However, this procedure has certain disadvantages that include the possibility of implant exposure, palpability or loosening of the screws, painful irritation, temperature sensitization, and radiographic artifacts. In this study, we compared the function and satisfaction outcome between Bonamates(®) bioabsorbable implant and Leibinger titanium implant...

Zygomatic hypoplasia can be an exceedingly difficult proposition for the surgeon treating facial deformity. The classical approach would be a coronal access, which is time-consuming, leaves a long scar on the scalp that shows in patients with balding patterns, and carries the risk of permanent facial weakness. The Edinburgh technique presents a minimal access approach to the zygomatic osteotomy. This is performed through local incisions and a bone cut made using hand-held diamond-coated wire that mobilizes the entire zygoma...

INTRODUCTION: Reconstruction of craniofacial defects due to traumatic injuries is a challenge for a reconstructive surgeon, given the functional impact, the aesthetic impact and the geometric complexity of the craniofacial skeleton. The use of cutting and repositioning guides enables a new approach from the craniofacial reconstruction with bone grafts on measure. We are presented to illustrate this technique the case of a patient. OBSERVATION: The patient was 50 years old, he presented a traumatic facial sequelar: a left frontal craniofacial deformation, an enlarged left orbit with enophthalmos and valgus left zygoma...

The purpose of this report is to evaluate the effectiveness of a high Le Fort I osteotomy design, including the malar bones, which allows segment sliding over the zygoma and forces the osteotomized segment to move forward with distraction. Two patients (male, 23-and 30-year-old) with malar deficiency underwent high Le Fort I osteotomy and surgically assisted rapid maxillary expansion procedure was followed. Records were taken before and 6 months after surgery for comparison, including intra and extra oral photographs and three-dimensional cone-beam computed tomography (CBCT) images...
