OBJECTIVE: Fractures of the zygoma and orbit are common facial skeleton injuries. Inadequate reduction and internal fixation may result in functional and aesthetic impairment. The aim of this study was to assess the use of intraoperative 3-dimensional (3-D) cone beam computed tomography (CBCT) for determining the intraoperative revision rate and the need for additional reconstruction of the orbit. STUDY DESIGN: We conducted a retrospective analysis of 48 consecutive patients (15 females, 33 males) suffering from simple or complex zygomatic fractures, seen between June 2015 and October 2016...

BACKGROUND: Dermoid cysts are rare tumors that are usually seen in the midline structure of the brain, but rarely arise in the petrous apex and cavernous sinus. There have been very few reports of dermoid cysts arising in the infratemporal fossa with scarce anatomical descriptions. Here, we report the case of a patient with a dermoid cyst in the left infratemporal fossa. CASE DESCRIPTION: The patient was a 43-year-old female with complaints of non-specific headaches...

Importance: Spontaneous cerebrospinal fluid leaks (sCSF-L) of the temporal bone are associated with obesity, calvarial thinning, and obstructive sleep apnea (OSA), and the incidence has doubled in the past decade. It is currently unknown if OSA is independently associated with skull thinning. Objective: To determine if patients with OSA have thinner skulls than patients without OSA. Design, Setting, and Participants: A retrospective cohort study of patients who underwent a level 1 polysomnogram (PSG) and also had high-resolution computed tomographic (CT) imaging of the head from January 2010 to March 2017 at Indiana University was carried out...

Richard A Hopper, Hitesh Kapadia, Srinivas M Susarla
In this technical note, the authors describe a technique for correction of exorbitism with simultaneous correction of central midface vertical and sagittal deficiency. The technique involves a combination of a Le Fort III osteotomy with a Le Fort II distraction. The Le Fort III osteotomy allows for repositioning and fixation of the zygomas to correct lateral hypoplasia and exorbitism and maintains the globes in this more functional position. The Le Fort II distraction allows for movement of the central midface independent of the lateral orbits and zygomas, allowing sagittal and vertical correction without orbital distortion...

The zygomaticomaxillary complex fractures are common fractures among the all facial fractures, and the zygomatic arch fracture accounts for approximately 10% of all facial fractures. Various routes (Gillies app, Direct cutaneous app, Bicoronal, intraoral) and devices (Foley's ballon catheter, Rowe zygoma elevator, Langenbach, deschamps needle holder, Bone hook) for a surgical intervention of the zygomatic arch have been introduced. However, no study exists that has described an effective method of surgery for zygomatic arch fractures that have been left untreated for a long period, or for unstable reduction that have not been reduced >1 month after surgery...

Intraosseous hemangioma is an extremely rare tumor that accounts for 1% or fewer of all osseous tumors. The most common sites of its occurrence are the vertebral column and calvaria. Occurrence in a facial bone is very rare. The authors aim to report a case of the surgical treatment of intraosseous hemangioma occurring in the periorbital region, which is a very rare site of occurrence and to introduce our own experiences with the diagnosis and treatment of this condition along with a literature review. A 73-year-old male patient visited our hospital with the chief complaint of a mass touching the left orbital rim...

Background: Actinomycosis israeli is a gram-positive non-acid-fast bacterium and is the most common causative agent of actinomycosis. It usually presents as a brain abscess via a secondary spread from the cervicofacial region or lungs. However, presentation as an en-plaque lesion with bone involvement out of proportion to brain parenchyma is rare and needs to be acknowledged. Case Description: We report a case of intracranial en-plaque lesion in a 47-year-old female with restriction of mouth opening and right third nerve palsy for 1 year...

Zygoma reduction malarplasty is a standard procedure primarily performed in Asia on patients who prefer an oval facial shape. The technique is well established and standardized. However, the esthetic results are frequently unsatisfactory or accompanied by complications such as nonunion, malunion, and cheek drooping. These complications are generally attributed to postoperative bone fragment movement. In this study, we present an improvement to this standard procedure that involves modifying the surgical technique...

The aim of this study is to search for the origin of the term "ligament' in the face, present its status, and suggest a principle to rectify the use of unclear terminology.The structure that connects the zygoma to the skin was first presented by McGregor (1959). Kaye (1981), in describing his "extended facelift," wrote that the adherent area of the cheek over the malar eminence (McGregor's patch) usually requires sharp dissection. Bosse (1987) reported that the zygomatic ligament is quite solidly bound to the malar eminence and usually requires sharp dissection to release it...

Maxillofacial injuries can be complex and are clinically important due to their functional and cosmetic significance. Maltreated and missed fractures might cause deformity of the face; thus, accurate evaluation of the fracture provided by X-ray images is critical. In this study, we explore the application of cone-beam computed tomography (CBCT) for diagnosis of severe maxillofacial traumas. A patient with a complex fracture that affects the maxilla, mandible, wall of the maxillary sinus, zygoma, zygomatic arch and nasal bone was diagnosed using 3D reconstruction of CBCT images...

Reduction malarplasty is utilized to reshape the facial form into an oval shape. However, complications and unfavorable results in reduction malarplasty have been reported. Reoperation of a nonunion malar complex is difficult relative to the achievement of a satisfactory outcome using the intraoral approach with a narrow surgical field because the normal anatomy has been destroyed, and previous surgery may have caused asymmetry. In this situation, computer-aided simulation surgery and surgical guides can serve as effective solutions to overcome the limitations of reoperative malarplasty using the intraoral approach...
