Background: The purpose of this study was to attempt to determine a reliable method of evaluating midface position. We assessed a novel parameter called WIZDOM (Width of the Interzygomatic Distance of the Midface) and its relationship to other facial metrics. Objectives: The goal was to evaluate midfacial position quantitatively in women by examining 2-dimensional photographs of a subset of women with idealized facial proportions. Methods: Three examiners analyzed stock photographs of nonsmiling female model faces...

Synkinetic movements are common among patients with incomplete recovery from facial palsy, with reported rates ranging from 9.1% to almost 100%. The authors propose the separation of the neural stimulus of the orbicularis oculi from that of the zygomatic muscular complex to treat eyelid closure/smiling synkinesis. This technique, associated with an anastomosis between the masseteric nerve and a central branch of the facial nerve, as well as with the use of a cross-facial nerve graft, resolves most of the spasms of the midface musculature, leading to a more relaxed tone when the mimic muscle is at rest and enhancing muscle excursion during voluntary and spontaneous smiling...

PURPOSE: The aim of this study was to describe radiological imaging findings of a complicated sinusitis, which should raise the suspicion of rhino-orbital-cerebral mucormycosis as being the underlying cause. METHODS: In this retrospective analysis, we describe the cases and imaging findings of 8 patients with proven mucormycosis. These patients presented mostly with new facial or orbital swelling and were referred for imaging to our institution. Magnetic resonance imaging and computed tomography images were classified as abnormal or normal with respect to orbital, paranasal and cerebral signal results...

Since electronic cigarette (ECIG) introduction to American markets in 2007, vaping has surged in popularity. Many, including women of reproductive age, also believe that ECIG use is safer than traditional tobacco cigarettes and is not hazardous when pregnant. However, there are few studies investigating the effects of ECIG exposure on the developing embryo and nothing is known about potential effects on craniofacial development. Therefore, we have tested the effects of several aerosolized e-cigarette liquids (e-cigAM) in an in vivo craniofacial model, Xenopus laevis, as well as a mammalian neural crest cell line...

This second article of a three-part series addresses techniques and recommendations for aesthetic treatment of the midface. Injectable fillers are important for rejuvenation of the midface by replacing lost volume and providing structural support; neuromodulators play a smaller role in this facial region. Fillers are used for volumization and contouring of the midface regions, including the upper cheek and lid-cheek junction and the submalar and preauricular areas. Also, treatment of the frontonasal angle, the dorsum, the nasolabial angle, and the columella may be used to shape and contour the nose...

Cleft lip and palate is the most common congenital craniofacial anomaly. Up to 60% of these patients will benefit from cleft orthognathic surgery, which consists primarily of maxillary advancement and mandibular setback to address midface retrusion and relative mandibular protrusion, respectively. It is believed that maxillary advancement can enlarge the airway whilst mandibular setback can reduce the airway, but this has not previously been quantified for cleft patients undergoing orthognathic surgery. This unique longitudinal prospective study of 18 patients was conducted between April 2013 and July 2016...

The pedicled buccal fat pad has occasionally been used for the closure of oroantral and oronasal fistulae. However, this versatile and convenient technique has not been used widely in the field of esthetic surgery. The main cosmetic interest in the buccal fat pads was to surgically extract them to reduce cheek prominence. Here, the authors introduce a novel operative technique using the pedicled buccal fat pad for midface augmentation in patients with deficient soft-tissue volume, particularly in the anterior malar or paranasal region...

BACKGROUND: Zygomatic arch is a bony arch constituting the lateral midface, which consists of 25% of all midface fractures. There are a number of ways to evaluate the extent of zygomatic arch fracture. Some authors have reported successful treatment outcomes using ultrasound (U/S). To add to the previous methods, we have considered ways to accurately display the location of the fracture line while using U/S with 23 gauge needle marking. We introduce our method, which provided satisfactory results for reduction using a portable U/S, and it can evaluate the fracture line simultaneously when reduction of an isolated zygomatic arch fracture is necessary, and needle marking, which can easily point out the fracture line on U/S...

The cleidocranial dysplasia is general skeletal disorder with an autosomal dominant inheritance. It is manifested by many craniofacial abnormalities, of which the maxillary hypoplasia is the most evident. The aim of the study was to use CBCT to evaluate the volume of the maxillary sinuses and the dimensions of maxillae in patients with CCD and compare them with healthy individuals. Files of four children with cleidocranial dysplasia were investigated. Volume of every maxillary sinus as well as two dimensional measurements of distances between particular points of interest located on surface of maxilla were calculated from reconstructed CBCT examination...

Nonsyndromic orofacial clefts (OFCs) are complex traits characterized by multifactorial inheritance and wide phenotypic variability. Numerous studies have shown subtle differences in the faces of unaffected relatives from cleft families compared to controls, the implication being that such outward differences are an incomplete expression reflecting an underlying genetic predisposition. Twins discordant for OFCs provide a unique opportunity to further test this idea, as the unaffected co-twin shares on average 50% (for dizygotic twins) and 100% (for monozygotic twins) of the genetic risk factors as the affected twin...

We present the case of a patient of Macedonian origin with unilateral renal agenesis and ureterovesical junction obstruction in combination with further abnormalities including midface hypoplasia, scoliosis as well as camptodactyly of one toe. Whole-exome sequencing analysis revealed compound heterozygous variants in the FAT4 gene. Recessive variants in FAT4 are a known cause of van Maldergem syndrome (VMS) in which congenital anomalies of the kidney and urinary tract are a less characteristic but common feature...

INTRODUCTION: Although orbital compartment syndrome is a rare condition, it is still the most common cause of blindness following simple or complicated facial fractures. Its pathomechanism is similar to the compartment syndrome in the limb. Little extra fluid (blood, oedema, brain, foreign body) in a non-space yielding space results with increasingly higher pressures within a short period of time. Unless urgent surgical intervention is performed the blocked circulation of the central retinal artery will result irreversible ophthalmic nerve damage and blindness...

INTRODUCTION: In this article, we aimed to establish an ideal definition for the craniofacial midsagittal plane (MSP) by first finding an optimal "plane of best fit" and then deriving a simple approximation for clinical use that is highly accurate. METHODS: For 60 adolescent patients, 3-dimensional coordinates of 8 central landmarks and 6 pairs of lateral landmarks were collected. Across all patients, the coplanarity of the central landmarks was compared with that of the midpoints of the lateral landmarks...

BACKGROUND: Soft tissue augmentation is increasingly being performed to treat male facial aging. OBJECTIVE: To review anatomical consideration specific for the male face and define an approach to male soft tissue augmentation that creates harmonious and natural results. CONCLUSION: Addressing aesthetic concerns in the upper face, midface, and lower face should be performed in concert with a combinatorial and pan facial approach. Correct filler placement at different areas of concern is important to achieve desired and natural results...

BACKGROUND: Maxillectomy defects significantly impair quality of life. Prosthetics can overcome some of these issues, but has limitations. The role of the osteocutaneous radial forearm free flap (OC-RFFF) has been established for reconstruction of smaller maxillectomy defects, but its role in larger defects is not well defined. We aim to evaluate outcomes after midface reconstruction utilizing the OC-RFFF. METHODS: Retrospective review of prospective database collected between 2005 and 2014 of midface reconstruction using OC-RFFF in a tertiary care centre...
