INTRODUCTION: The gastrocnemius muscular flap has already proven its efficiency for soft tissue coverage in cases of knee joint exposure. However, it may be too small to cover large defects and has not the same aesthetic and mechanical properties as normal skin. Perforator fasciocutaneous flaps have recently been described in knee joint coverage with good results as they replace skin by skin, but they can be hard to harvest. Gastrocnemius flaps can be easily harvested with a planned skin paddle designed over the chosen muscle...

Background: HFM patients' reconstruction has always been a challenge for maxillofacial surgeons, and numerous reconstructive techniques have been described. Surgical treatment depends on the patient's age and contemplates Temporomandibular Joint (TMJ) reconstruction in conjunction with orthognathic surgery, usually necessary following completion of growth to maximize the functional and esthetic results. Distraction osteogenesis had gained popularity as valid alternative in growing patients, but the two primary methods to reconstruct the TMJs involve the use of autogenous, using free or microvascular bone grafts, or alloplastic graft, but there is no widely accepted method...

PURPOSES: Bone tumours have been a tragedy for the patient in any time period. In the majority of the cases it occurs in children or young adults. In the past the affected limbs could not be spared and the overall prognosis was poor. METHODS: Chemotherapy successfully introduced for the purpose of overcoming the poor overall prognosis (Rosen and Jaffe) and tumour prostheses were invented for the purpose of salvaging the affected limbs (Marcove, Scales, Campanacci, Sivas, Salzer)...

PURPOSE OF REVIEW: A growing number of transgender patients are seeking gender-affirming genital reconstructive surgery (GRS). These complex procedures have high complication rates. We describe common surgical pitfalls in GRS and approaches for minimizing complications. RECENT FINDINGS: Penile inversion vaginoplasty has been associated with excellent cosmetic and functional outcomes. A robotic-assisted dissection may minimize risk of rectal injury. As a younger transgender population chooses pubertal suppression, alternative sources for lining the vaginal canal, such as enteric vaginoplasties, may be more widely utilized...

The growing interest in minimally invasive implant placement and delivery of a prefabricated provisional prosthesis immediately, thus minimizing "time to teeth," has led to the development of numerous 3-dimensional (3D) planning software programs. Given the enhancements associated with fully digital workflows, such as better 3D soft-tissue visualization and virtual tooth rendering, computer-guided implant surgery and immediate function has become an effective and reliable procedure. This article describes how modern implant planning software programs provide a comprehensive digital platform that enables efficient interplay between the surgical and restorative aspects of implant treatment...

In recent years, there have been a growing number of procedures involving dental implants. Most cases, though, are characterized by bone atrophy, especially horizontal atrophy. This clinical case aims to report a technique for the expansion of the horizontal alveolar ridge. A longitudinal fracture was created in the alveolar ridge to expand the bone, followed by immediate insertion of dental implants along with a particulate allogeneic bone graft. Eight implants were placed in the maxilla, and after 12 months, a surgical reopening was performed, along with rehabilitation with a protocol-type prosthesis, for which a zirconia infrastructure was made...

Opioid analgesics and antibiotics prescribed by dentists is a useful and cost-effective measure when prescribed appropriately. Common dental conditions are best managed by extracting the offending tooth, restoring the tooth with an appropriate filling material, performing root canal therapy, and/or fabricating a prosthesis for the edentulous space. Unnecessary prescription of opioid analgesics and antibiotics to treat dental pain and bacterial infection is a growing public health concern. This article highlights the state of the literature on opioid analgesic and antibiotic prescribing practices in dentistry, the impact of opioid analgesic overdose, and prevention strategies to reduce opioid analgesics and antibiotic overprescription...

Titanium (Ti) is the most widely used metal in biomedical applications because of its biocompatibility; however, the significant difference in the mechanical properties between Ti and the surrounding tissues results in stress shielding which is detrimental for load-bearing tissues. In the current study, to attenuate the stress shielding effect, a new processing route was developed. It aimed at growing thick poly(methyl methacrylate) (PMMA) layers grafted on Ti substrates to incorporate a polymer component on Ti implants...

BACKGROUND: The prevalence of obesity with aging is escalating alarmingly; and pelvic organ prolapse (POP) and stress urinary incontinence (SUI) are now becoming a growing epidemic among the elderly. Synthetic transvaginal mesh has been employed with increasing popularity in the treatment of POP and is usually highly effective in controlling the principal symptoms of prolapse. However, studies have reported that mesh operations provide fairly unfavorable SUI cure rates. Therefore, additional anti-incontinence surgical strategies are increasingly being scrutinized to achieve better postoperative continence without any significant side-effects for patients with both POP and SUI...

Transcatheter aortic valve replacement (TAVR) has been approved in the United States for intermediate and high-risk patients with severe symptomatic aortic stenosis. More than 80 000 TAVR procedures have been performed in the United States and the number is growing every year. Two valve designs are approved in the United States including the balloon expandable Edwards Sapien prosthesis and self-expanding CoreValve prosthesis. The PARTNER trial of the Sapien valve, involving patients who were considered inoperable, reported a 19% absolute risk reduction in mortality compared with medical therapy, with a number needed to treat of 5...
