The Association of Zygomaticomaxillary Complex Fractures with Naso-Orbitoethmoid Fractures in Pediatric Populations.

Plast Reconstr Surg 2021 Apr 7. Epub 2021 Apr 7.

From the Department of Plastic and Reconstructive Surgery, Johns Hopkins Hospital; the Department of Biostatistics, Boston University School of Public Health; and the Division of Plastic and Reconstructive Surgery, Department of Surgery, Rush Medical College.

Background: Naso-orbitoethmoid fractures associated with ipsilateral zygomaticomaxillary complex fractures are more challenging injuries than zygomaticomaxillary complex fractures alone. However, there is a paucity of information on this complex fracture pattern in the pediatric population. This study investigated the cause, treatment, and outcomes of combined zygomaticomaxillary complex and naso-orbitoethmoid fractures versus isolated zygomaticomaxillary complex fractures in pediatric patients.

The Rhino-Lip-Lifting: A Novel Proposal for Midface Profileplasty Performed as a Single Surgical Procedure.

Facial Plast Surg 2021 Apr 8. Epub 2021 Apr 8.

Department of Facial Plastic Surgery, Rigeneralab Center for Regenerative Medicine, Torino, Italy.

As facial aging occurs, aesthetic changes of the nasal tip and the senile upper lip include tip ptosis, increase in skin length, loss of vermillion height and Cupid's bow, and vertical wrinkles.Regardless of the rejuvenation procedure, the lips are not to be considered as a single anatomical entity, instead they should be placed in a strong correlation with the nose. The aim of this study is therefore to demonstrate the effectiveness of the association of primary closed rhinoplasty together with indirect subnasal lip-lifting technique. Read More

Bilateral Orbital Reconstruction With Autologous Bone Graft After Gunshot Wound to Upper Midface.

Cureus 2021 Feb 28;13(2):e13611. Epub 2021 Feb 28.

Plastic Surgery, University of Iowa Hospitals and Clinics, Iowa City, USA.

Ballistic maxillofacial injuries are highly destructive, producing significant morbidity and mortality. Survivors' defects pose unique reconstructive challenges, such as loss of periorbital bone stock in upper midface injuries. While orbital reconstruction has transitioned from primarily autologous grafts to alloplastic implants, ballistic trauma remains a niche that warrants the use of autologous bone equally with alloplastic materials.

Accuracy of Computer-Assisted Surgery in Maxillary Reconstruction: A Systematic Review.

J Clin Med 2021 Mar 16;10(6). Epub 2021 Mar 16.

Department of Oral and Maxillofacial Surgery/Pathology, Amsterdam UMC and Academic Center for Dentistry Amsterdam (ACTA), Vrije Universiteit Amsterdam, De Boelelaan 1117, 1081 HV Amsterdam, The Netherlands.

Computer-assisted surgery (CAS) in maxillary reconstruction has proven its value regarding more predictable postoperative results. However, the accuracy evaluation methods differ between studies, and no meta-analysis has been performed yet. A systematic review was performed in the PubMed, Embase, and Cochrane Library databases, using a Patient, Intervention, Comparison and Outcome (PICO) method: (P) patients in need of maxillary reconstruction using free osteocutaneous tissue transfer, (I) reconstructed according to a virtual plan in CAS software, (C) compared to the actual postoperative result, and (O) postoperatively measured by a quantitative accuracy assessment) search strategy, and was reported according to the PRISMA statement.

Cells 2021 Mar 8;10(3). Epub 2021 Mar 8.

Department of Plastic, Aesthetic and Reconstructive Surgery, University of Regensburg, Franz-Josef-Strauss-Allee 11, D-93053 Regensburg, Germany.

Lipofilling is a popular technique to treat volume loss in aging patients. The isolated adipose tissue is composed of adipocytes and stromal vascular fraction cells, which include adipose-derived stem cells (ASC). We hypothesize that the patient's wrinkle severity scale (WSS) and patient's satisfaction on the global aesthetic improvement scale (GAIS) can be improved after using concentrated lipoaspirate.

Aesthet Surg J Open Forum 2021 Jan 11;3(1):ojaa045. Epub 2020 Nov 11.

McGaw Medical Center, Northwestern University, Chicago, IL, USA.

Postoperative cicatricial lower lid retraction is a challenging surgical problem that often disfigures the shape of the eye and has functional consequences. Depending on the severity, more than one surgical procedure may be needed to achieve the desired lower lid shape and position given the recurrent nature of scarring. Concepts of scar release, establishing lower lid vertical height, soft tissue replacement, and midcheek support are discussed in this video. Read More

Biomechanical Impact of a Zygoma Complex Fracture Using Human Cadaver.

J Craniofac Surg 2021 Mar 22. Epub 2021 Mar 22.

Graduate Program in Biomedical Engineering, The University of Western Ontario Schulich School of Medicine and Dentistry, The University of Western Ontario Otolaryngology-Head and Neck Surgery, The University of Western Ontario Mechanical and Materials Engineering, The University of Western Ontario, London, Ontario, Canada.

Abstract: Zygomaticomaxillary complex fractures are common in midface trauma, with treatment often involving repair using titanium mini plates. However, the need for plate fixation along the zygomaticomaxillary suture on the infraorbital rim remains controversial. This study utilized a previously reported bite force simulator to investigate craniofacial strain patterns following zygomaticomaxillary complex fracture repairs with and without plating of the infraorbital rim.

Alloplastic Facial Implants.

Facial Plast Surg 2021 Mar 16. Epub 2021 Mar 16.

Division of Facial Plastic and Reconstructive Surgery, Department of Otolaryngology, Head and Neck Surgery, University of Minnesota, Minneapolis, Minnesota.

As the face ages, there is thinning of the epidermis, volume loss and rearrangement of the soft tissues, and malabsorption of the skeletal framework. It is essential to have a thorough understanding of the aging process for successful facial augmentation and rejuvenation. Alloplastic implants can be used to provide a long-lasting solution for augmentation of skeletal deficiencies, restoration of facial irregularities, and rejuvenation of the face. Read More

Was facial width-to-height ratio subject to sexual selection pressures? A life course approach.

PLoS One 2021 12;16(3):e0240284. Epub 2021 Mar 12.

Department of Anthropology, University of California, Santa Barbara, California, United States of America.

Sexual selection researchers have traditionally focused on adult sex differences; however, the schedule and pattern of sex-specific ontogeny can provide insights unobtainable from an exclusive focus on adults. Recently, it has been debated whether facial width-to-height ratio (fWHR; bi-zygomatic breadth divided by midface height) is a human secondary sexual characteristic (SSC). Here, we review current evidence, then address this debate using ontogenetic evidence, which has been under-explored in fWHR research. Read More
