PURPOSE: Reduction malarplasty is one of the most common esthetic surgical procedures performed in the Asian population. Traditional procedures have several complications, such as bone nonunion, malunion, cheek drooping, and damage to the infraorbital nerve and maxillary sinus. Therefore, a more straightforward and effective method of reducing the width of the midface is needed. In this study, we introduce an infracture technique using inward displacement of the zygomatic arch without fixation...

INTRODUCTION: Previous reports indicated that there is geographic and sociodemographic variation in the epidemiology of maxillofacial fractures. Audit of maxillofacial injuries managed at any institution is therefore necessary to understand the trends and proffer strategies for prevention. We therefore embarked on this study to determine the pattern of maxillofacial fractures and concomitant injuries in our institution. METHODS: We carried out a retrospective review of information on demography, aetiology and type of maxillofacial fracture, patients' status, type of crash, level of consciousness and concomitant injuries...

OBJECTIVE: The aim of this study was to describe a technique for midface rejuvenation combining lower blepharoplasty, midcheek lift and autologous fat transfer. METHODS: All patients who underwent a midface rejuvenation procedure performed by the same surgeon and using a classic subciliary blepharoplasty surgical approach were identified. The technique combined three distinct procedures: lower blepharoplasty with use of a transposition flap of orbital adipose tissue in the medial and central compartment to reduce the subpalpebral bags and attenuate the palpebrojugual sulcus; midcheek lift in the preperiosteal plane with trans-osseous fixation exerting traction on the soft tissues of the cheek along several vectors; autologous fat transfer to offset the loss of volume in the target area...

This article describes our surgical technique for subperiosteal midface elevation in patients with paralytic lower eyelid malposition or cicatricial inferior eyelid retraction. Nineteen patients with paralytic lower eyelid malposition and 15 patients with cicatricial inferior eyelid retraction underwent a subperiosteal midface lift (n = 34). The procedure was performed under local anesthesia through three nonvisible incisions. A transconjunctival incision allows preseptal dissection to the orbital rim, followed by a subperiosteal dissection of the midface...

Holoprosencephaly (HPE), a common developmental defect of the forebrain and midface, has a complex etiology. Heterozygous, loss-of-function mutations in the Sonic hedgehog (SHH) pathway are associated with HPE. However, mutation carriers display highly variable clinical presentation, leading to an "autosomal dominant with modifier" model, in which the penetrance and expressivity of a predisposing mutation is graded by genetic or environmental modifiers. Such modifiers have not been identified. Boc encodes a SHH co-receptor and is a silent HPE modifier gene in mice...

In the evolution of cleft lip repair, there have been continuous attempts to minimize local trauma and to improve lip and nasal appearances. In order to obtain an aesthetically balanced development of midface, the primary surgical correction of the nasolabial area is of paramount importance. In this study, the importance of a back-cut extending cephalically above the inferior turbinate at the mucocutaneous junction which elevates the nostril floor on the cleft side for the purpose of achieving symmetry of the alar bases are analyzed by pre and postoperative photographic anthropometry...

REVIEW
Lauren K Reckley, Jessica J Peck, Scottie B Roofe
Paramedian forehead and melolabial flaps are the most common examples of interpolated flaps used by facial plastic surgeons and are excellent options for reconstruction of the midface after Mohs surgery. They provide superior tissue match in terms of thickness, texture, and color, while leaving minimal defects at the tissue donor sites. The main advantage of interpolated flaps is the robust blood supply, which can be either axial of randomly based, and the maintenance of the integrity of facial landmarks. The main disadvantage is the frequent need for a multistage procedure, which eliminates some patients from consideration...

Integration of the sphenoid and ethmoid bones during early postnatal development is poorly described in the literature. A uniquely prolonged patency of sphenoethmoidal synchondrosis, or prespheno-septal synchondrosis (PSept) has been attributed to humans. However, the sphenoethmoidal junction has not been studied using a comparative primate sample. Here, we examined development of the sphenoethmoidal interface using ontogenetic samples of Old and New World monkeys, strepsirrhine primates (lemurs and lorises), and a comparative sample of other mammals...

S Hosseini-Farahabadi, S J Gignac, A Danescu, K Fu, J M Richman
The study of rare genetic diseases provides valuable insights into human gene function. Here, we investigate dominant Robinow syndrome (RS), which affects the WNT5A signaling pathway. Autosomal dominant RS is caused by missense mutations in WNT5A or nonsense mutations in the adaptor protein DVL1 or DVL3. The recessive form of the disease is caused by loss-of-function mutations in the receptor ROR2. RS is characterized by hypertelorism, midface, and mandibular hypoplasia. Here, we focus on the missense mutations in WNT5A, since the impact on function is difficult to predict from in silico analysis...

Mosaic trisomy 5 is a very rare condition in liveborns, with few cases reported in the last four decades. There are some reports of prenatally diagnosed mosaic trisomy 5 resulting in phenotypically normal offspring, suggesting a low level of mosaicism, but there are also reports associated with multiple congenital anomalies, cardiovascular malformations, and intrauterine growth restriction. We report an infant male diagnosed with mosaic trisomy 5 (5/15 cells) via amniocentesis. The patient was subsequently found to have uniparental disomy 5 (UPD5) by postnatal chromosome microarray, but high-resolution chromosome analysis on peripheral blood did not identify trisomy 5...

PURPOSE: Volumetric or multiplane defects of the upper and midface remain a challenge for reconstruction because of limited regional flap options. In this study, the authors harvested the reverse temporalis muscle flap and pericranial flap (RTMP flap) based on the same vascular pedicle, the superficial temporal artery, in a chimeric manner to obtain double-layer closure of deep facial defects. MATERIALS AND METHODS: This study was a prospective case series performed in the Department of Plastic Surgery of Ataturk University (Erzurum, Turkey)...
