The Pitanguy ligament is a crucial structure in nasal tip support and in maintaining the integrity of the soft tissue envelope of the nose. In this cadaveric study, we dissected out the Pitanguy ligament on a series of fresh human cadaver specimens to better elucidate the structure of the ligament and its fate in open rhinoplasty. The Pitanguy ligament can act as a tethering force to the nasal tip when reshaping the nasal tip.

Autografting with split-thickness skin grafts (STSG) remains an essential procedure in burn and reconstructive surgery. The process of harvesting STSG, however, leaves behind a donor site, an exposed area of partial-thickness dermis left to heal by secondary intention. There has yet to be a consensus amongst surgeons regarding optimal management of the donor site.

On-surface polymerization of functional organic molecules has been recently recognized as a promising route to persistent low-dimensional structures with tailorable properties. In this contribution, using the coarse-grained Monte Carlo simulation method, we study the initial stage of the Ullmann coupling of doubly halogenated chrysene isomers adsorbed on a catalytically active (111) crystalline surface. To that end, we focus on the formation of labile metal-organic precursor structures preceding the covalent bonding of chrysene monomers.

Hemangiomas of the nasal tip are a relatively uncommon presentation of a common tumor. While optimal medical and surgical management of nasal tip infantile hemangiomas has been described and debated extensively in the literature, to our knowledge, there is no report of secondary aesthetic and functional rhinoplasty in these patients at skeletal maturity, until now. This special topic article provides an excellent example of the 5 key technical elements to revision rhinoplasty in the skeletally mature patient with a history of nasal tip infantile hemangioma.

The diversity of surface-confined metal-organic precursor structures, which recently have been observed experimentally, poses a question of how the individual properties of a molecular building block determine those of the resulting superstructure. To answer this question, we use the Monte Carlo simulation technique to model the self-assembly of metal-organic precursors that precede the covalent polymerization of halogenated PAH isomers. For this purpose, a few representative examples of low-dimensional constructs were studied, and their basic structural features were quantified using such descriptors as the orientational order parameter, radial distribution function, and one- and two-dimensional structure factors.

A particularly prominent mandibular angle or a hypertrophied masseter muscle can result in an excessively wide facial appearance, which some individuals may find less aesthetically pleasing. Although normally a benign condition and strictly an aesthetic concern, a hypertrophied masseter can also cause pain, bruxism, and headaches. Neuromodulator for masseter reduction and treatment of bruxism has become first-line treatment.

Summary: Alar base surgery is approached with hesitancy and is often avoided by many surgeons because of inexperience and a lack of understanding. However, with a thorough knowledge of the anatomy and dynamic nature of the lower third of the nose, alar base resection can achieve favorable and reproducible results. Beyond correcting alar flare, an appropriately diagnosed and performed alar base procedure serves to contour both the alar rim and the alar base.

The lip lift is a powerful yet finesse operation in the realm of facial rejuvenation. In an era of increased popularity of nonsurgical lip augmentation, the astute plastic surgeon must identify which patients will end up with an unnatural appearance should they receive volume enhancement alone in pursuit of central facial and perioral rejuvenation. In this article, the authors review the ideal youthful lip appearance, characteristics of the aged lip appearance, and indications for lifting.

Neuromodulators have become a treatment of choice for the management of excess gingival show, or "gummy smile." There have been many proposed algorithms for the optimal placement and dosage of neuromodulator to inject in these locations. The authors aim to clarify these points and provide surgeons with a reliable way to manage the gummy smile that results from hyperactive muscles of the midface.

Revision rhinoplasty is a finesse procedure requiring careful consideration of all of its requisite steps. Lateral osteotomies are required in many cases and, in the setting of prior lateral osteotomies, can often be recreated with digital pressure alone, without the use of an osteotome. The advantages of doing so include decreased dead-space creation and preservation of attachments between the skeleton and overlying soft tissue.

Background: Mastopexy and reduction mammaplasty are commonly performed procedures in plastic surgery with many variations in incision pattern, pedicle design, and additional support maneuvers. Aesthetically pleasing on table results are widely accomplished; however, the longevity of the outcome and sustained correction of ptosis or pseudoptosis is not universal. A systematic review of mastopexy and reduction mammaplasty procedures was performed to investigate which techniques provided the greatest long-term correction of ptosis.

The availability of advanced telecommunication technology and the social restrictions introduced by a global pandemic have compelled the medical community to explore new avenues of surgical education. Although cadaver courses have long been a fundamental method for learning surgical anatomy and improving operative preparedness, the COVID-19 pandemic has made traditional dissections less practical. The need for quality virtual learning experiences motivated the authors to design and assess the feasibility of organizing a live, virtual upper extremity peripheral nerve cadaver dissection course.

Background: Computed tomography (CT)-based quantitative analysis of primary ossification centres in the cranium has not been carried out to date due to the limited availability of the foetal human material. Detailed morphometric data about the development of primary ossification centres in human foetuses may be useful in the early detection of developmental defects. Understanding the growth and development of the occipital bone is crucial in assessing the normal and pathological development of the cranial base, and the cranium as a whole.
