BACKGROUND: Lower eyelid retraction can be the unfortunate result of aesthetic surgery, trauma, disease or simply aging processes. The purpose of this article is to assess whether midface lifting based on purely vertical repositioning constitutes an effective procedure for its correction. METHODS: A retrospective study was carried out on 199 patients (311 eyelids) operated on between January 2004 and January 2014. The various causes of eyelid retraction in this population comprised cosmetic blepharoplasty (56...

BACKGROUND: Cleft Lip with or without Palate (CL/P) is present in approximately 1 in 500-700 live births, representing the most common congenital craniofacial anomaly. Previously, we developed a unique murine model with compound Pbx deficiency that exhibits fully penetrant CL/P. To investigate the possibility of tissue repair at an early gestational stage, we designed a minimally invasive surgical approach suitable for intrauterine repair using Wnt9b-soaked collagen microspheres to restore craniofacial developmental programs for cleft correction...

Blast-induced traumatic brain injury (TBI) has been on the rise in recent years due to the increasing use of improvised explosive devices (IEDs) in conflict zones. Our study investigates the response of a helmeted human head subjected to a blast of 1 atm peak overpressure, for cases with and without a standard polycarbonate (PC) face shield and for face shields comprising of composite PC and aerogel materials and with lateral edge extension. The novel introduction of aerogel into the laminate face shield is explored and its wave-structure interaction mechanics and performance in blast mitigation is analysed...

We report the case of a 7-month-old girl with atypical oculo-facio-cardio-dental syndrome (OFCD). A novel de novo pathogenic mutation in the BCL6 interacting co-repressor gene (BCOR) (c.4540C>T; p.Arg1514*), was identified on the X chromosome. This case expands the phenotype of OFCD as it is the first report of a case presenting with craniosynostois, temporal hypertrichosis, supraorbital grooving, and underdevelopment of the midface.

This technical protocol outlines the use of computer-assisted image-guided technology for the preoperative planning and intraoperative procedures involved in implant-retained facial prosthetic treatment. A contributing factor for a successful prosthetic restoration is accurate preoperative planning to identify prosthetically driven implant locations that maximize bone contact and enhance cosmetic outcomes. Navigational systems virtually transfer precise digital planning into the operative field for placing implants to support prosthetic restorations...

INTRODUCTION: The purpose of this study is to demonstrate the surgical technique for the correction of midfacial deformities; vertical excess and posteroanterior hypoplasia. This situation obligates the need to move the whole osseous structure in an oblique posteroanterior movement that should correct both midfacial deformities. This should also correct the lip incompetence while improving the malar projection on a profile view of the patient. We also present a mathematical formula that gives the angulation needed for moving the midface complex in a simultaneous vertical and posteroanterior direction...

PURPOSE: We will aim to develop implants made of a Ni-Ti shape memory alloy which can be applied for the treatment of midface fractures, such as isolated orbital floor fractures. These can then be implanted in a compressed form and unfold automatically in the body. With the help of newly developed application instruments, the implants can be applied along transnasal and transantral approaches into the maxillary sinus. Our objective is to evaluate the operation process and the functionality of these implants, already in a pre-investigation by an experienced surgeon on a phantom...

We report a case of congenital orbital teratoma. A 3-day-old male, born at 39 weeks' gestation without relevant prenatal history, presented with a large vascularized proptotic mass distorting the left midface. Laboratory studies showed elevated serum alpha-fetoprotein (12,910 ng/ml). Computed tomography showed a multiloculated heterogeneous lesion composed of hypodense and hyperdense calcified areas encompassing the whole orbital cavity with expansion of the bony walls, as well as forward displacement and compression of the eyeball without extension to surrounding structures...

Aging changes to the lower eyelids and midface include pseudoherniated orbital fat, tear trough deformity, lid laxity, and dermatochalasis. Surgical repair often aims at treating redundant skin or orbital fat malposition with a lower eyelid blepharoplasty. Either a transcutaneous or transconjunctival approach may be used, though recent trends have favored the transconjunctival technique if procedures require more than simple skin excision. In manipulating the inferior orbital fat pads, a surgeon has many options including excision, repositioning, or augmentation with synthetic dermal filler, autologous fat grafts, or acellular dermal allografts...

We created the Ontology of Craniofacial Development and Malformation (OCDM) [1] to provide a unifying framework for organizing and integrating craniofacial data ranging from genes to clinical phenotypes from multi-species. Within this framework we focused on spatio-structural representation of anatomical entities related to craniofacial development and malformation, such as craniosynostosis and midface hypoplasia. Animal models are used to support human studies and so we built multi-species ontologies that would allow for cross-species correlation of anatomical information...

CONTEXT: Several studies showed, from the clinical point of view, the advantages of the various techniques and surgical approaches to obtain facial rejuvenation. A few studies have highlighted the satisfaction or not of patients who underwent a traditional facelift; however, a long-term follow-up study measuring patient satisfaction with midface-lift surgery has not been published yet. AIMS: The aim of this study is to measure individual patient satisfaction with the midface lift, to find out from each patient his/her level of satisfaction 1 and 5 years after the operation and to compare the results to assess the benefits of the surgery...

Facial feminization surgery is a term to describe the surgical alteration of a masculine facial appearance to a more feminine appearance, which is most commonly performed for male-to-female transsexual individuals. To alter the midfacial relations, segmentalized osteotomies were performed in selected patients expanding on the established techniques for facial feminization surgery. All patients underwent a preoperative 3D computerized tomography scan and 3D photography before and after the surgery. The inclusion of the midface in surgery was determined based on the relative projection and angle of the zygomatic body compared with the supraorbital region (the supraorbital region was reduced in all patients)...

PURPOSE: This study evaluates the accuracy of a statistical shape model (SSM) for virtual fracture reconstruction of the lateral midface. MATERIALS AND METHODS: A uniform bony defect of the right zygoma was created. A virtual reconstruction was performed by using the standard procedure of mirroring the unaffected to the affected side (Group I) and by using the statistical model based on 178 pathologically unaffected CT scans (Group II). The accuracy of the statistical shape model was evaluated in comparison to the present mirroring protocol...

The bilateral sagittal split mandibular osteotomy (BSSMO), a common maxillofacial technique for expanding the oropharynx during treatment of micrognathia, is a rarely employed but useful adjunct to improve surgical access to the ventral cervical spine in children. Specifically, it provides enhanced exposure of the craniocervical junction in the context of midface hypoplasia, and of the subaxial cervical spine in children with severe kyphosis. The authors describe their technique for BSSMO and evaluate long-term outcomes in patients...

Porous polyethylene (PPE) implants are biocompatible alloplastic materials commonly used for facial augmentation. However, the effect of sub-periosteal PPE application on the surrounding tissues has not been analyzed clearly. This report documents the case of a 22-year-old woman who underwent peri-alar augmentation with PPE to improve midface retrusion. Although no infection or inflammation occurred at the surgical site, the patient requested removal of the PPE implant for aesthetic reasons alone at 1 year after the surgery...
