Sir Harold Gillies first described rotating a band of temporalis muscle over the zygoma where the muscle sling was augmented with strips of fascia lata to rehabilitate facial paralysis (1) . McLaughlin later modified this technique in the 1950s without inversion of the temporal muscle but in an orthodromic manner thus avoiding the soft tissue fullness over the zygomatic arch area and depression of the donor site (2) . Although several refinements of this technique have been described, all required skin incisions on the face until a transoral technique was described recently by this clinical group (3) ...

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...

Andrew Dawood, Nicholas Kalavresos
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...

Yasuhiro Takahashi, Hirohiko Kakizaki
A bifurcated periosteal flap is useful for simultaneous reconstruction of the upper and lower lateral canthal tendons. The original technique harvested the flap horizontally from the frontal process of the zygoma, which mostly resulted in an insufficient flap length because of the narrowness of the zygoma. Here, the authors report the use of a modified bifurcated periosteal flap, raised from the superolateral orbital rim. The lower flap was positioned to slant inferiorly to create a downward slope of the lower eyelid for smooth lacrimal drainage by gravity...

The etiology of fractures of the maxillofacial skeleton varies among studies, with motor vehicle accidents and assaults oftentimes the most common. The number of males outnumbers females throughout most studies. Fractures of the zygoma, orbit, and mandible are usually cited as most common fracture types. This study examines a single center's experience with regards to etiology and distribution of fractures. A retrospective review of all radiologically confirmed facial fractures in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012...

REVIEW
David B Powers, Elda Fisher, Detlev Erdmann
Intraosseous hemangiomas are uncommon intrabony lesions, representing approximately 0.5 to 1% of all intraosseous tumors. Their description varies from "benign vasoformative neoplasms" to true hamartomatous proliferations of endothelial cells forming a vascular network with intermixed fibrous connective tissue stroma. These commonly present as a firm, painless swelling. Intraosseous hemangiomas present more commonly in females than in males and most likely occur in the fourth decade of life. The most common etiology of intraosseous hemangioma is believed to be prior trauma to the area...

PURPOSE: This study evaluates the accuracy of a statistical shape model (SSM) for virtual fracture reconstruction of the lateral midface. MATERIALS AND METHODS: A uniform bony defect of the right zygoma was created. A virtual reconstruction was performed by using the standard procedure of mirroring the unaffected to the affected side (Group I) and by using the statistical model based on 178 pathologically unaffected CT scans (Group II). The accuracy of the statistical shape model was evaluated in comparison to the present mirroring protocol...

INTRODUCTION: Faciomaxillary fractures (FMF) occur in a significant proportion of trauma patients. Nearly all polytrauma patients and even those with isolated FMF are managed under general anesthesia for definitive management. We propose the use of regional nerve blocks as a safe and effective means for open reduction and fixation of isolated FMF. AIM AND OBJECTIVES: The aim is to evaluate the feasibility, effectiveness and safety of base of skull maxillomandibular and distal trigeminal nerve blocks in the management of FMF...

David C G Sainsbury, Alan George, Christopher R Forrest, John H Phillips
The authors performed bilateral malar reconstruction using polyether ether ketone implants in 3 patients with Treacher-Collins syndrome with absent, as opposed to hypoplastic, zygomata. These patient-specific implants were fabricated using computed-aided design software reformatted from three-dimensional bony preoperative computed tomography images. The first time the authors performed this procedure the implant compressed the globe resulting in temporary anisocoria that was quickly recognized intraoperatively...

INTRODUCTION: The recent finding that shrinkage of key areas of the facial skeleton contributes to the aging appearance of the face has prompted a search for the most appropriate bone-like implant material. Evidence that hydroxyapatite, in granular form, maintains volume in the long term supports its use in the correction of aging, in addition to its use in the correction of inherently deficient areas of the facial skeleton. The biologic response of hydroxyapatite needs to be fully understood for its use to be confidently recommended...
