A New Technique for Coronaplasty in Penile Reconstruction.
2018
Abstract Background The coronaplasty is an important step of the phalloplasty procedure as it creates a prominent coronal ridge and a constricted coronal sulcus, resulting in the transformation of a regular skin flap into a flap resembling a circumcised penis. Aim The aim of this article is to describe our new coronaplasty technique that exploits opposing contracting forces of 2 different skin grafts to hold the shape of a thick, distally based skin flap, resulting in a natural looking neo-phallus. Methods A distally based flap is raised at the junction of the middle and distal thirds of the neo-phallus. The dissection continues until adequate mobilization is obtained, so the flap can stand…
Clinical parameters of implants placed in healed sites using flapped and flapless techniques: A systematic review
2017
Background: Dental implant placement using flapless surgery is a minimally invasive technique that improves blood supply compared with flapped surgery. However, the flapless technique does not provide access to allow bone regeneration. Objectives: The aim of this systematic review was to evaluate the clinical parameters following implant surgery in healed sites, using two procedures: flapped vs. flapless surgery. Material and Methods: A detailed electronic search was carried out in the PubMed/Medline, Embase and Cochrane Library databases. The focused question was, “How do flapped and flapless surgical techniques affect the clinical parameters of dental implants placed in healed sites?”. Al…
Propeller Flaps: A Review of Indications, Technique, and Results
2014
In the last years, propeller flaps have become an appealing option for coverage of a large range of defects. Besides having a more reliable vascular pedicle than traditional flap, propeller flaps allow for great freedom in design and for wide mobilization that extend the possibility of reconstructing difficult wounds with local tissues and minimal donor-site morbidity. They also allow one-stage reconstruction of defects that usually require multiple procedures. Harvesting of a propeller flap requires accurate patient selection, preoperative planning, and dissection technique. Complication rate can be kept low, provided that potential problems are prevented, promptly recognized, and adequate…
Evaluation of cut quality using the Amadeus microkeratome with different settings.
2004
Abstract Purpose: To evaluate the quality of keratectomy specimens created with the Amadeus® microkeratome (AMO) using scanning electron microscopy (SEM). Setting: Johannes Gutenberg-University Hospital, Department of Ophthalmology, Mainz, and the Department of Anatomy, Justus Liebig-University, Giessen, Germany. Methods: Corneal cuts were performed in freshly enucleated pig eyes using the Amadeus microkeratome with 9 combinations of oscillation rate and head-advance speed. For the cutting trials, oscillation rates of 8000, 13000, and 18000 rpm and head-advance speeds of 1.0, 2.5, and 4.0 mm/s were chosen. Fifty-four eyes were included, resulting in 9 groups of 6 eyes for each configuration…
The foot fillet flap for ischial pressure sore reconstruction: A new indication
2018
Abstract Introduction The main cause of ischial pressure sores in paraplegic patients is prolonged sitting without pressure relief. These wounds are subject to recurrence and may need repeated reconstruction with local flaps. When all options are exhausted, the total thigh flap is the last resort. Disarticulation of the hip joint impairs stability even when sitting and causes subsequently very high discomfort. In this manuscript, we describe an alternative to the total thigh flap to avoid hip disarticulation: the foot fillet flap. Materials & Methods This study was performed on four patients at the department of Plastic & Reconstructive Surgery of the Ghent University Hospital, Belgium. Inc…
Lentiviral transduction of face and limb flaps: implications for immunomodulation of vascularized composite allografts.
2012
Background Ex vivo introduction of an immunomodulatory transgene into a face or hand allograft may improve the risk-to-benefit ratio of vascularized composite allografts. Abrogation of the immunogenicity of the skin component of a face or hand allograft may decrease alloreactivity and permit the induction of immunologic tolerance. Proof-of-principle demonstrations of transduction of composite tissue have been established using adenoviral vectors, producing transient gene expression. The authors hypothesized that transduction, integration, and long-term expression of transgenes in a vascularized composite allograft could be achieved using lentiviral vectors. Methods Ex vivo transduction of h…
Meta-analytic study on the frequency and treatment of oral antral communications
2010
Objective: To determine the optimum surgical treatment for oral antral communications (OAC) and to understand the main post-operative complications.Study Design: Meta-analytical, observational and retrospective study of 1,072 cases of OAC obtained from a literature review of 15 articles. Results: OAC occur slightly more often in men and during the fourth decade of life. Its primary etiological factor is dental extraction, most often affecting the third molar. The most common treatment has been the use of Bichat's fat pad grafts, whereas the technique with the highest percentage of complications has been the use of the palatal rotation flap. The most frequent complication has been the fistul…
Botulinum toxin in preparation of oral cavity for microsurgical reconstruction.
2010
CONCLUSIONS: Infiltration of botulinum toxin in the major salivary glands allows a temporary reduction of salivation that begins 8 days afterwards and returns to normal within 2 months. The inhibition of salivary secretion, carried out before the oral cavity reconstructive surgery, could allow a reduction of the incidence of oro-cutaneous fistulas and local complications. OBJECTIVES: Saliva stagnation is a risk factor for patients who have to undergo reconstructive microsurgery of the oral cavity, because of fistula formation and local complications in the oral cavity. The authors suggest infiltration of botulinum toxin in the major salivary glands to reduce salivation temporarily during th…
Noninvasive Flap Preconditioning by Foam-Mediated External Suction Improves the Survival of Fasciocutaneous Axial-Pattern Flaps in a Type 2 Diabetic …
2018
Background Advances in reconstructive surgery are leading to an increased number of flaps at risk for ischemic necrosis, because of either intrinsic (e.g., larger flap size) or extrinsic (e.g., diabetes) factors. Methods to preoperatively improve flap vascularity and limit postoperative ischemia are lacking. Noninvasive suction, using either a macrodeformational silicone cup interface (external volume expansion) or a microdeformational polyurethane foam interface (foam-mediated external volume expansion), has been shown to induce angiogenesis in tissues. The authors investigated whether the preoperative use of external volume expansion/foam-mediated external volume expansion improves flap s…
Technique des membranes induites en chirurgie maxillo-faciale
2012
Maxillofacial defects reconstruction represents a formidable challenge to achieve both functional and aesthetic goals. To succeed, numerous parameters must be taken into account: patient's general conditions, defect's location, width and type of the defect and eventual donor sites which can provide the tissues. Routine reconstructions include bone transplantation (autologous, homologous or heterologous), implantation of biomaterials and osteogenic distraction. The advantages of these techniques are evident, but they are usually limited by their complexity in patients with bad general health. The technique of induced membranes needs to be more known in maxillofacial surgery.
