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...

The Early to Late Oligocene Propalaeocastor is the earliest known beaver genus from Eurasia. Although many species of this genus have been described, these species are defined based on very fragmentary specimens. Propalaeocastor irtyshensis from the Early Oligocene Irtysh River Formation in northwestern Xinjiang, China is one of the earliest-known members of Propalaeocastor. This species is defined on a single maxillary fragment. We revise the diagnosis of P. irtyshensis and the genus Propalaeocastor, based on newly discovered specimens from the Irtysh River Formation...

A novel surgical treatment sequence for secondary orbitozygomatic complex (OZC) reconstruction is described. Orbital reconstruction is performed before OZC repositioning. A surgical plan is made: the affected OZC is virtually osteotomized and aligned with a mirrored model of the unaffected OZC. A patient-specific implant (PSI) is designed for orbital reconstruction. Screw holes from the primary reconstruction are used for fixation. Primary screw hole positions at the repositioned OZC are embedded in the design, to guide OZC repositioning...

This study uses five well-documented cranial nonmetric traits (glabella, mastoid process, mental eminence, supraorbital margin, and nuchal crest) and one additional trait (zygomatic extension) to develop a validated decision tree for sex assessment. The decision tree was built and cross-validated on a sample of 293 U.S. White individuals from the William M. Bass Donated Skeletal Collection. Ordinal scores from the six traits were analyzed using the partition modeling option in JMP Pro 12. A holdout sample of 50 skulls was used to test the model...

The association of traumatic head injury (THI) with maxillofacial fractures (MFF) is a major health concern worldwide. In spite of the close anatomical proximity of maxillofacial bones to the cranium, the association of THI with MFF is controversial. The aim of this study was to assess the association between traumatic head injuries (THI) and maxillofacial fractures (MFF). Other factors associated with THI in patients with MFF were also investigated MATERIALS AND METHODS: A hospital-based retrospective study was conducted at the OMFS Unit, Hospital USM, Kelantan, Malaysia...

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...

Patterns of wear on the canine teeth were examined in 260 adult male babirusa skulls. Video recordings of 161 adult male babirusas at salt licks in North Sulawesi were viewed for behaviour related to erosion of the canine teeth. Corresponding observations were made of the behaviour of male babirusa in Antwerp and Surabaya Zoos. Most loss of maxillary canine dental tissue was from the ventro-lateral or lateral surface of the tooth, towards its distal end. The teeth were smoothly flattened on a plane approximating to the plane formed on the side of the face by the snout, the zygion and the zygomatic process...

J N Philip, D F Campbell
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...

In recent years, several studies related to fixation systems have been published, but few suggest any variations of the Le Fort I osteotomy technique, and the use of plates and screws placed along the canine and zygomatic pillar are common. The 20-year-old patient with Crouzon syndrome presented with severe hypoplasia of the maxillary, mandibular prognathism, and class III facial pattern. The patient underwent orthognathic surgery and high Le Fort I osteotomy with the fixation of eight positional screws. The aim of this paper is to describe a different technique for the fixation in high maxillary osteotomies, which can be used in specific cases...
