BACKGROUND: The available referential measures defining the zygomatic bone morphology are adequate enough for full determination of the zygoma positioning, especially for trauma surgery, but osteometric analysis of the zygoma positioning based on tomographic examinations could be useful in peroperative and postoperative imaging. In this study, we propose referential measures, taking into account the morphology and the symmetry of the zygoma. In addition, the reliability and reproducibility are considered...

PURPOSE: Lateral displacement of fracture zygomaticomaxillary complex (ZMC) can cause significant increase in orbital volume leading to enophthalmos. The aim of this study was to radiologically evaluate the efficacy of sphenozygomatic (SZ) suture fixation for restoration of orbital volume after elevation of the temporalis in cases of fracture ZMC where the fixation of zygomatic arch (ZA) was deemed necessary through latero-posterior approach. MATERIALS & METHODS: 43 operated cases of fracture ZMC using 4-point fixation were divided into two groups...

PURPOSE: During surgery for major maxillofacial fractures, orotracheal intubation can interfere with some surgical procedures and nasal intubation can be contraindicated or impossible. That is why tracheotomy is presented as a solution, although it carries a relatively high incidence of complications. In this study, the use of submandibular tracheal intubation is basically evaluated as an alternative to tracheotomy in such circumstances. MATERIALS AND METHODS: This prospective study was performed in patients undergoing surgery for major maxillofacial fractures in which oral intubation and/or nasal intubation have been unsuitable, impossible, or contraindicated...

The craniofacial skeleton is often described in the clinical literature as being comprised of vertical bony pillars, which transmit forces from the toothrow to the neurocranium as axial compressive stresses, reinforced transversely by buttresses. Here, we review the literature on bony microarchitecture, in vivo bone strain, and finite-element modeling of the facial skeleton of humans and nonhuman primates to address questions regarding the structural and functional existence of facial pillars and buttresses...

BACKGROUND AND AIM: This study aims at evaluating the reliability on specific multi-planar cone beam computer tomography (CBCT) reconstruction in the orbital floor fractures. METHODS: CBCT examination of the mid-face fractures area involving the floor of the orbit was performed in a number of 93 trauma patients by two independent radiologists. Both radiologists assessed the axial, coronal and sagittal sections and also the oblique coronal and sagittal extracted sections evaluating the location of the orbital fractures, its size and displacement, the involvement of the infra-orbital foramen, herniation of fat or muscle within the maxillary sinus, the overall type of the fracture and the implication of lateral or medial orbital wall...

This article presents an unusual case of maxillary sinus mucocele as a late complication of zygomatic-orbital complex fracture, 23 years after the initial treatment. The patient was referring diplopia and decreased visual acuity with signs of dystopia, proptosis, and epiphora. Computed tomographic scan revealed an expansive lesion in the maxillary sinus with surrounding bone erosion and displacement of the eyeball. Treatment option was excisional biopsy and orbital floor reconstruction with titanium mesh restoring the appropriate orbital position...

PURPOSE: The intraoral quadrangular Le Fort II osteotomy (IQLFIIO) represents a reliable surgical method in cases of midfacial deficiency with good functional, esthetic, and stable long-term results. PATIENTS AND METHODS: In this technical note, we present 3 surgical modifications to previous reports: 1) inferior orbital rim osteotomy by angulated piezosurgical instruments, thereby avoiding the use of chisels in the orbital region; 2) osteosynthetic fixation only laterally at the zygomatic buttress with 2 L-shaped miniplates, thus avoiding paranasal osteosynthesis; and 3) advancement step camouflage in the lateral infraorbital region with a compound mass of autologous bone chips and fibrin glue with the intention to reduce bone block-associated side effects...

INTRODUCTION: In recent years, bioresorbable plates have undergone remarkable development. However, there has been no attendant improvement in their strength, because strength requires thickness, and complications such as palpability are related to the thickness of bioresorbable plate systems. In this clinical study, we compared the surgical management of zygomatic fractures using newly developed thinner bioresorbable materials or conventional titanium miniplates. METHODS: Twelve patients with zygomatic fractures were randomly divided equally into 2 groups (6 with new bioresorbable osteosynthesis materials and 6 with standard titanium miniplates)...

Ballistic injuries of oral and maxillofacial region are usually fatal due to close propinquity with the vital structures. The severity of injury depends on the caliber of the weapon used and distance from which the patient is shot. The preliminary care of facial ballistic wounds strictly adheres to the basics of trauma resuscitation. Early and appropriate surgical management has proved to be influential on the final outcome and esthetic result. Treatment of facial gunshot wounds should be planned and carried out carefully to avoid esthetic complications...

Fractures of the zygoma are relatively frequent and their management has been extensively described. Above all, isolated zygomatic arch fractures comprise about 10% of all zygomatic fractures. Temporal approach is common surgical method, Gillies approach, but it has the limitation of blinded surgical approach. So, the mobile intraoperative fluoroscan is used famously for more suitable reduction, but it needs an additional man to control the machine and increases irradiation doses. The authors got the simple idea, but so helpful tool, and it has been performed since 2012...

Zygomatico-maxillary complex fractures present a challenging diagnostic and reconstructive task to the surgeon. Gillie's temporal approach has been a commonly used technique for zygomatic arch reduction but surgeons have been commonly using a buccal sulcus approach for the reduction of zygomatic arch fractures as well as for combined zygomatico-maxillary complex fractures. This paper outlines the use of Rowe's elevator (modification of Bristow's elevator) intra-orally to reduce zygomatic arch fractures and if required, simultaneously plate the zygoma through the same approach...
