#1
Peter J Hundt, Andrew M Simons
The dentition of fishes can be quite striking and is often correlated with a specific diet. Combtooth blennies have long incisiform oral teeth, unlike most actinopterygians. It has been suggested that the long tooth morphology is an adaptation for detritivory, but given the diversity of diets (detritus, coral polyps, polychaetes, and pieces of other fishes), are blenny teeth indeed monomorphic? Or does tooth variation associated with diet still exist at this extreme? To explore tooth and diet diversification, we used a new phylogenetic hypothesis of Blenniidae, measured tooth shape, number, and mode of attachment, and quantified blenniid diet...

BACKGROUND: Perioperative pain, increased sympathetic tone, and peripheral vasospasm may be safely managed with regional nerve blockade during microvascular reconstruction in the lower extremity. Limited reports exist in this setting; therefore, we evaluated our use of peripheral nerve catheters (PNCs) during microvascular limb salvage to determine safety and efficacy for both patient and flap. METHODS: A single-institution, retrospective review of a prospectively maintained database on all patients with lower extremity free tissue transfers between 2012 and 2017 was completed...

Ameloblastoma is an aggressive odontogenic tumor which typically occurs between third and fourth decade of life that often needs resective approach. Immediate reconstruction may show better results. The treatment of multicystic ameloblastoma in the mandible being a rare case that occurred in the late second decade of life, which was surgically removed along with the affected teeth with safety margins, and the region was immediately reconstructed using a vascularized graft, removed from the fibula. Its integration, in combination with osseointegrated dental implants and fixed implant-supported prostheses, restored chewing function and esthetics...

Total esophagogastric dissociation (TED) is used to treat gastroesophageal reflux (GER) after failed fundoplication in neurologically impaired patients. It is now performed for some otherwise healthy patients with severe GER. In this procedure, the gastrointestinal tract is reconstructed in a non-physiological way with a Roux-en-Y esophagojejunal anastomosis and jejuno-jejunostomy. Although TED eliminates almost all GER, some patients experience late complications. In this review, we investigated the long-term outcomes after TED to determine the best indications...

BACKGROUND: Mandibular reconstruction after ablative surgery is challenging not only for the amount of bone tissue needed following bone loss after benign or malignant tumor surgical removal, but mainly to reconstruct bone shape and structure necessary for subsequent implant insertion to preserve the function (speech, swallowing and chewing) and aesthetic of the lower face. Several different techniques for maxillary bone defects reconstruction have been described. The aim of our work is to describe a new technique for mandibular reconstruction that uses an intramural distractor, which is placed in one surgical step and without the need for a skin incision...

BACKGROUND: Lengthening temporalis myoplasty is a faster and less invasive alternative to free muscle transfer for smile reconstruction. However, it requires a nasolabial fold incision, which leaves a midfacial scar. Based on esthetic considerations, a modified approach, involving an extended lazy-S (parotidectomy) incision instead of a nasolabial fold incision, was developed. METHODS: A cadaveric study involving 10 hemifaces was conducted. From February 2013 to March 2016, the modified lengthening temporalis myoplasty procedure was employed in 10 patients...

INTRODUCTION: We aimed to compare alternative synthetic scaffolds suitable for future implantation and to examine the use of an inhibitor of lysyl oxidase (beta-amino- propionitrile [β-APN]) to reduce contraction in these implants. METHODS: Three synthetic scaffolds were compared to natural dermis as substrates for the production of tissue-engineered skin. For natural dermis, Euroskin was used to provide a cell-free cadaveric dermis. Synthetic scaffolds consisted of microfibrous PLA, nanofibrous PHBV, and a micro-/nanofibrous trilayer of PLA-PHBV-PLA...

The anterolateral thigh flap (ALT) is a workhorse for a spectrum of reconstructive problems including head and neck defects. Its versatility as a chimeric flap employing a variety of soft tissues with a robust pedicle is useful for three-dimensional defects. The authors investigated the anatomical relationship between the vascular supply to the ALT and anterior femur. We studied 16 fresh cadaver limbs to identify the typical branching patterns to the femur off the descending branch of the lateral circumflex femoral artery...
