Sean Delaney, Russell W H Kridel
Background: The midface is particularly prone to the senescent changes of soft tissue ptosis and volume loss, which in individuals with aging or low adiposity can manifest as submalar hollowing. Facelift alone in those with submalar hollowing inadequately addresses the volume loss and may result in a gaunt appearance postoperatively. Submalar implant augmentation is a powerful tool for permanent midface volume restoration for a more youthful and natural contour, as opposed to soft tissue fillers that diminish over time...

BACKGROUND: Facial aging is a complex process influencing every layer of the facial structure. Most accepted surgical techniques for facial rejuvenation involve certain manipulation of the superficial musculoaponeurotic system (SMAS). Out of these SMAS-based techniques, SMAS plication or suspension provides excellent outcomes with shorter convalescence and fewer potential complications. Herein, we would like to present our own technique combining SMAS plication, periauricular purse-string, and malar fat pad elevation technique for mid and lower facelift...

Late epistaxis after rhinoplasty is a rare but potentially life-threatening occurrence. This case report concerns a 20-year-old woman who had severe epistaxis 5 and 10 days after a closed rhinoplasty with internal osteotomies and who ultimately required transcatheter arterial embolization for definitive control of the hemorrhagic source. Arterial hypervascularity, with signs of arteriovenous malformation, of the midface at the level of the piriform aperture and maxilla was seen on angiography.

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...

Orofacial clefting represents the most common craniofacial birth defect. Cleft lip with or without cleft palate (CL/P) is genetically distinct from cleft palate only (CPO). Numerous transcription factors (TFs) regulate normal development of the midface, comprising the premaxilla, maxilla and palatine bones, through control of basic cellular behaviors. Within the Pbx family of genes encoding Three Amino-acid Loop Extension (TALE) homeodomain-containing TFs, we previously established that in the mouse, Pbx1 plays a preeminent role in midfacial morphogenesis, and Pbx2 and Pbx3 execute collaborative functions in domains of coexpression...

Achim G Beule
Only about 8% of head and neck tumors affect the midface. This anatomical area is characterized by an enormous number of functionally important structures, and it is frequently only possible to achieve small resection margin distances. To avoid complications and unfavorable results, a dedicated preparation of both patient and surgeon is warranted. This review aims to provide encouragement for the postgraduate training of interested ENT specialists. Following the clinical course and based on recent literature, strategies to avoid complications of tumor surgery to the midface are given...

Background: Nasal fracture and orbital blowout fracture often occur concurrently in cases of midface blunt trauma. Generally, these multiple fractures treatment is surgery, and typically, the nasal bone and orbit are operated on separately. However, we have found that utilizing a transconjunctival approach in patients with concurrent nasal bone fracture and orbital blowout fracture is a useful method. Methods: The participants in the present study included 33 patients who visited the Plastic Surgery outpatient department between March 2014 and March 2017 and underwent surgery for nasal fracture and orbital blowout fracture...

Le Fort III distraction osteogenesis may be indicated in the treatment of syndromic craniosynostosis with severe midface retrusion and proptosis. This study assesses the stability of proptosis correction over 10-years.A retrospective review identified 15 patients with syndromic craniosynostosis treated by Le Fort III distraction prior to age 10 (9 males, 6 females; age 4.9 ± 1.5 years). Untreated, non-craniosynostotic age- and gender-matched controls were obtained from historical growth records. Lateral cephalometric tracings at pre-surgery (T1), immediate (T2), 1 year (T3), 5 years (T4), and 10 years (T5) (n = 11) post-distraction were superimposed using the best-fit of cranial base...

Mingi Hong, Robert S Krauss
Holoprosencephaly (HPE) is a common developmental defect caused by failure to define the midline of the forebrain and/or midface. HPE is associated with heterozygous mutations in Nodal and Sonic hedgehog (SHH) pathway components, but clinical presentation is highly variable, and many mutation carriers are unaffected. It is therefore thought that such mutations interact with more common modifiers, genetic and/or environmental, to produce severe patterning defects. Modifiers are difficult to identify, as their effects are context-dependent and occur within the complex genetic and environmental landscapes that characterize human populations...
