PURPOSE: Maxillofacial fractures represent a serious public health problem. Their epidemiology is extremely variable, and its analysis is crucial to establish effective treatment and prevention of these injuries. However only two works have been published about maxillofacial fracture epidemiology in Italy. MATERIALS AND METHODS: The records of 1720 patients diagnosed with maxillofacial fractures in a 15-years period (2001-2015) in our department were retrospectively reviewed...

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...

This case report describes a patient with ankyloglossia, oligodontia, unilateral hypoplasia of the zygoma and mandible, along with bilateral distal reduction anomalies of his limbs without long bone abnormalities. This may represent a mild variant of oromandibular limb hypogenesis syndrome, expanding the phenotypic spectrum, or a previously unrecognized malformation syndrome.

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...

Hae-Won Yang, Jin-Joo Hong, Youn-Taek Koo
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...

OBJECTIVES: As intraosseous venous malformations (IVMs) of the zygoma are very rare and clinical features are not typical, a correct preoperative diagnosis may be difficult to make. This study presents 4 cases of IVM of the zygoma and gives a review of their clinical manifestations, radiographic features, preoperative diagnosis, and differentials. METHODS: The report of 4 cases was performed with an average 6-year follow-up. Medical records including clinical, radiographic, and histopathological information were reviewed...

PURPOSE: The zygomaticofacial/temporal/orbital nerve is a terminal branch of the zygomatic nerve and exits the orbit through zygomatic foramina. The nomenclature in the literature varies with some studies identifying all 3 foramina on the malar surface of the zygoma, while others describe each along different aspects of the zygoma. In this study, foramen on the malar surface of the zygoma is termed zygomatic foramen, and the authors describe anatomical variations in the position and number of these foramina in an African American population...

BACKGROUND: The aim of the study was to detect by skin high-frequency ultrasound (US) possible subclinical skin involvement in patients affected by limited cutaneous systemic sclerosis (lcSSc), in those skin areas apparently not affected by the disease on the basis of a normal modified Rodnan skin score (mRSS). Differences in dermal thickness (DT) in comparison with healthy subjects were investigated. METHODS: Fifty patients with lcSSc (age 62 ± 13 years (mean ± SD), disease duration 5 ± 5 years) and 50 sex-matched and age-matched healthy subjects (age 62 ± 11 years) were enrolled...

In patients with fractures of the zygomatic complex, computed tomography (CT) often identifies extensive defects in the orbital floor. Some surgeons recommend routine exploration and repair of these defects during repair of the zygoma, while others advocate a more selective approach, but there is a paucity of evidence either way. We report a retrospective case series of 50 patients who had open reduction and internal fixation of zygomatic fractures by a single surgeon in the maxillofacial department at the John Radcliffe Hospital, Oxford, between 2011and 2014...

This article details the significant complications associated with treatment of a patient who underwent maxillary reconstruction based entirely on zygomatic implants. The use of zygomatic implants is becoming increasingly widespread, and treatment has been shown to be predictable and generally free of surgical complications. However, extending from the maxillary alveolus, alongside or through the maxillary antrum, toward the zygoma or orbital rim, these long implants have the potential to create a range of complications that may be more serious than those encountered with conventional dental implants...

BACKGROUND: We have adopted an intraoral microsurgical anastomosis to the facial vessels to eliminate the need for any visible facial incisions. METHODS: Cadaveric dissection was used to demonstrate accessibility of the facial artery and vein through an intraoral approach. Additionally, 5 patients underwent free tissue transfer for reconstruction of major defects of the midface through an intraoral, transmucosal approach, obviating the need for visible skin incisions...
