Tae Sung Lee, Sanghoon Park
The pedicled buccal fat pad has occasionally been used for the closure of oroantral and oronasal fistulae. However, this versatile and convenient technique has not been used widely in the field of esthetic surgery. The main cosmetic interest in the buccal fat pads was to surgically extract them to reduce cheek prominence. Here, the authors introduce a novel operative technique using the pedicled buccal fat pad for midface augmentation in patients with deficient soft-tissue volume, particularly in the anterior malar or paranasal region...

Most knowledge concerning Mesozoic Era floras has come from compression fossils. This has been augmented in the last 20 years by rarer permineralized material showing cellular preservation. Here, we describe a new genus of anatomically preserved gymnosperm seed from the Callovian-Oxfordian (Jurassic) Oxford Clay Formation (UK), using a combination of traditional sectioning and synchrotron radiation X-ray micro-tomography (SRXMT). Oxfordiana motturii gen. et sp. nov. is large and bilaterally symmetrical. It has prominent external ribs, and has a three-layered integument comprising: a narrow outer layer of thick walled cells; a thick middle parenchymatous layer; and innermost a thin fleshy layer...

Autologous lipofilling is a relatively new method of reconstructing congenital and acquired soft tissue defects. However, long-term results are unpredictable due to varying survival rate of the fat graft, and additional treatments are often required. We present a case of a 53-year-old woman who had a right hemifacial soft tissue deficit and received lipofilling twice with no complications and satisfactory cosmetic results. We consider conventional lipofilling to be safe and viable for facial soft tissue augmentation...

Connective tissue grafting is a means of developing stable and natural-looking soft-tissue architecture. The use of a subepithelial connective tissue graft (SCTG) has been successful in achieving root coverage and augmenting tissue thickness. Tunnel techniques enable root coverage with results that appear natural. These techniques can be applied to the treatment of dental implants with gingival recession. The purpose of this article is to demonstrate the use of a SCTG and a lateral access pouch in the treatment of multiple gingival recession defects affecting adjacent implants...

BACKGROUND: Age-related volume loss in the temporal fossae is due to thinning of the epidermis, loss of subcutaneous structural volume, and change in the bony architecture. Temporal concavities are important areas of 3-dimensional volume restoration. The temporal fossae is becoming an increasingly popular area for patients seeking soft tissue augmentation with injectable fillers such as calcium hydroxylapatite with integral lidocaine [CaHA (+)]. OBJECTIVE: This pilot study aims to define the safety, efficacy, technique, and patient-reported outcomes for injectable CaHA (+) to correct volume loss in the temporal fossae over a 12-month period...

In the past decade, adipose tissue has become a highly interesting source of adult stem cells for plastic surgery and regenerative medicine. The adipose source offers two options for the isolation of regenerative cells: the enzymatic digestion an expensive time-consuming procedure lacking a common standard operating protocol, or the non-enzymatic dissociation methods based on mechanical forces to break the processed adipose tissue. Here, we propose innovative inexpensive non-enzymatic protocols to collect and concentrate clinically useful regenerative cells from adipose tissue by centrifugation of the infranatant fraction of lipoaspirate as first step, usually discarded as a byproduct of the surgical procedure, and by fat shaking and wash as second enrichment step...

Advances in mechanobiology have evolved through insights from multiple disciplines including structural engineering, biomechanics, vascular biology, and orthopaedics. In this paper, we reviewed the impact of key reports related to the study of applied loads on tissues and cells and the resulting signal transduction pathways. We addressed how technology has helped advance the burgeoning field of mechanobiology (over 33,600 publications from 1970 to 2016). We analyzed the impact of critical ideas and then determined how these concepts influenced the mechanobiology field by looking at the citation frequency of these reports as well as tracking how the overall number of citations within the field changed over time...

Guided bone regeneration has become more predictable due to advances in material sciences. Nevertheless, vertical ridge augmentation (VRA) remains a potential challenge due to the complexity of soft tissue management. This becomes more complicated in the posterior atrophic mandible due to limited access and poorer blood supply. As such, a number of critical elements must be taken into consideration in treatment planning. Anatomical structures potentially jeopardize intraoperative adverse events such as bleeding or neurosensory disturbances...
