Does abdominoplasty have a positive influence on quality of life, self-esteem, and emotional stability?

Background: In a previous prospective study, the authors evaluated the quality of life in patients undergoing aesthetic surgery. In this survey, the authors split up the operative indication and analyzed quality of life, self-esteem, and emotional stability after abdominoplasty alone.

Methods: Sixty-three patients participated in the study.

Three-dimensional evaluation of breast augmentation and the influence of anatomic and round implants on operative breast shape changes.

Background: Currently, postoperative outcome analysis in breast augmentation is essentially subjective, and objective evaluation of treatment efficacy is lacking. This study evaluates the influence of anatomic and round implant parameters on breast contour changes after subpectoral breast augmentation using three-dimensional (3D) surface imaging.

Methods: 3D surface breast scans of 17 patients (34 breasts) undergoing subpectoral breast augmentation with round implants and of ten patients (20 breasts) receiving anatomic implants via an axillary approach under endoscopic assistance or a submammary fold incision were obtained before and 6 months postoperatively.

Peripheral nerve reconstruction with collagen tubes filled with denatured autologous muscle tissue in the rat model.

Conventional nerve conduits lack cellular and extracellular guidance structures critical for bridging larger defects. In this study, an exogenous matrix for axonal regeneration was provided by pretreated muscle tissue. In 24 rats, 14-mm sciatic nerve segments were resected and surgically reconstructed using one of the following methods: autograft (AG); bovine type I collagen conduit; (MDM) collagen tube filled with modified denatured autologous muscle tissue.

Three-dimensional evaluation of breast contour and volume changes following subpectoral augmentation mammaplasty over 6 months.

Background: Changes in breast-morphology occur after all types of breast surgery, but a systematic and objective surgical result assessment is currently lacking. Three-dimensional (3-D) surface imaging offers the ability to quantitatively evaluate breast contour, shape, surface and volume changes after surgery. This study evaluates 3-D breast contour and volume changes after breast augmentation over time.

Women's quality of life and surgical long-term outcome after breast reconstruction in Poland syndrome patients.

Background: In the last decades, several surgical approaches have been used to improve the appearance and quality of life of female Poland syndrome patients. The aim of this study was to analyze the women's quality of life and long-term outcome after breast reconstruction.

Methods: Forty-nine women with Poland syndrome who were treated surgically between 1974 and 2007 received standardized questionnaires to evaluate their quality of life and satisfaction after surgical treatment.

Successful anatomic repair of fetoscopic access sites in the mid-gestational rabbit model using amnion cell engineering.

Background/aim: Our aim was to evaluate the impact of in vitro cultured amnion cells, injected and/or seeded in different scaffolds, on in vivo fetal membrane repair.

Materials And Methods: Amnion cells, isolated from allogeneic fetal membranes, were cultured on three different scaffolds for 14 to 21 days. In 33 mid-gestational rabbits, fetoscopic access sites were randomly allocated to four closure study groups: conventional collagen plug, as well as collagen plug, collagen foil, and fibrin glue as scaffolds for the cultured amnion cells.

The free vascularized fibular epiphyseal transfer: long-term results of wrist reconstruction in young patients.

To date, the dominant blood supply to the head of the fibula and to the growth plate is known to be the anterior tibial artery. The peroneal artery had been used before, among other donor pedicles, for microvascular transfers of this epiphyseal region. This study presents the long-term results of this now obsolete pedicle and compares them to other reports in the literature.

Searching for the right timing of surgical delay: angiogenesis, vascular endothelial growth factor and perfusion changes in a skin-flap model.

Background: The angiogenic potential of vascular endothelial growth factor (VEGF) and its oxygen pressure-dependent regulation suggest a strong connection between this growth factor and the 'delay phenomenon'. In this study we focused on the chronological changes in VEGF concentration and flap perfusion in order to optimise the duration of surgical delay.

Methods: The VEGF concentration in skin and underlying muscle was measured in oversized, random-pattern flaps on 38 male Sprague-Dawley rats after 3, 5 or 7 days of surgical delay.

Mandibular reconstruction with free osteofasciocutaneous fibula flap: a 10 years experience.

The aim of this study was to evaluate the usefulness of the free osteofasciocutaneous fibular flap in mandible reconstruction in 23 patients. We reviewed their clinical records and asked the subjects to answer a questionnaire, as well as to attend our hospital for a clinical and radiological examination. The mean follow up was 1.

The use of free prelaminated and sensate osteofasciocutaneous fibular flap in phalloplasty.

The aim of this study was to present our latest modified protocol on neophallus construction that we have applied in 32 female-to-male transsexuals. The applied protocol consisted of neourethra prelamination with split skin thickness grafting at the lateral donor lower leg, and neophallus construction after 6 months with the free, prelaminated, and sensate osteofasciocutaneous fibular flap, followed by urethro-urethral anastomosis. Because of initial difficulties on harvesting and positioning the fibular flap, we had 2 total and 4 partial necrosis.

Fetoscopic closure of punctured fetal membranes with acellular human amnion plugs in a rabbit model.

Objective: To explore a surgical plug formed from decellularized term human amnion membrane for fetoscopic closure of iatrogenic defects in fetal membranes in a rabbit model.

Methods: The study was performed in eight rabbit does. Punctures were created at midgestational day 23 by 14-gauge needle fetoscopy on surgically exposed rabbit amniotic sacs.

Electrophysiologic assessment of sciatic nerve regeneration in the rat: surrounding limb muscles feature strongly in recordings from the gastrocnemius muscle.

Striking inconsistencies between the results of morphometric and electrophysiologic examinations of the regenerating nerve were observed in a previous study featuring the bridging of a 14 mm gap in the rat sciatic nerve. To shed light on this dichotomy, seven further rats were subjected to permanent sciatic nerve transection and assessed electrophysiologically, histologically and by retrograde axonal tracing at various postoperative intervals (1 h to 8 weeks). The results of the histological examinations and retrograde tracing revealed that in spite of the fact that compound muscle action potentials could be recorded in the gastrocnemius muscle, no reinnervation of the gastrocnemius muscle, either physiological or aberrant, had actually taken place.

New aspects of breast volume measurement using 3-dimensional surface imaging.

Precise and objective calculation of breast volume is helpful to evaluate the aesthetic result of breast surgery, but traditional methods are unsatisfactory. Three-dimensional (3D) scanning of the body surface allows reproducible and objective assessment of the complex breast region but requires further investigation before clinical application. The main goal of this study was to investigate the precision and accuracy of breast volume measurement using 3D body scanning.

Comparison between breast volume measurement using 3D surface imaging and classical techniques.

Quantification of the complex breast region can be helpful in breast surgery, which is shaped by subjective influences. However, there is no generally recognized method for breast volume calculation. Three-dimensional (3D) body surface imaging represents a new alternative for breast volume computation.

Amnion cells engineering: a new perspective in fetal membrane healing after intrauterine surgery?

In this study we aimed to set up an in vitro culture of the rabbit amnion in order to support in vivo fetal membrane healing capacity following fetoscopy. Fetal membranes were collected from a mid-gestational rabbit, and cultured on collagen support material for 14 days. 34 rabbits at 22-23 days gestational age (GA) underwent fetoscopy.

Optimization of 3-dimensional imaging of the breast region with 3-dimensional laser scanners.

The anatomic conditions of the female breast require imaging the breast region 3-dimensionally in a normal standing position for quality assurance and for surgery planning or surgery simulation. The goal of this work was to optimize the imaging technology for the mammary region with a 3-dimensional (3D) laser scanner, to evaluate the precision and accuracy of the method, and to allow optimum data reproducibility. Avoiding the influence of biotic factors, such as mobility, we tested the most favorable imaging technology on dummy models for scanner-related factors such as the scanner position in comparison with the torso and the number of scanners and single shots.

Three-dimensional cephalometric evaluation of maxillary growth following in utero repair of cleft lip and alveolar-like defects in the mid-gestational sheep model.

Objective: To evaluate maxillary growth following in utero repair of surgically created cleft lip and alveolar (CLA)-like defects by means of three-dimensional (3D) computer tomographic (CT) cephalometric analysis in the mid-gestational sheep model.

Methods: In 12 sheep fetuses a unilateral CLA-like defect was created in utero (untreated control group: 4 fetuses). Four different bone grafts were used for the alveolar defect closure.

Study of the neovascularisation of prefabrication of flaps using a silicone sheet and an isolated arterial pedicle: experimental study in rabbits.

Use of an isolated artery as an implanted pedicle in prefabricated flaps has rarely been reported either clinically or experimentally. In Chinchilla Bastard rabbits (n = 36), we dissected an isolated arterial pedicle from the femoral and saphenous artery, anastomosed it end-to-end to the femoral vein at the inguinal ligament and created an isolated arterial loop pedicle. This was implanted and fixed with polyglactin 9/0 under a random-pattern vascularised abdominal fasciocutaneous flap.

Three-dimensional fetal cephalometry: an evaluation of the reliability of cephalometric measurements based on three-dimensional CT reconstructions and on dry skulls of sheep fetuses.

Aim: To develop a 3D CT cephalometric analysis for maxillary growth evaluation of sheep fetuses operated in utero, and to evaluate the reliability of this analysis by comparing it with a direct cephalometric analysis on dry skulls.

Material And Methods: Five skulls of operated sheep fetuses were used, which after preparation were CT scanned and a 3D reconstruction was performed. A cephalometric analysis was performed directly on the dry skulls as well as on the reconstructed 3D CT images.

Patterns of subchondral bone mineralization in the distal radioulnar joint.

Purpose: Studies have shown that it is possible to derive direct knowledge about the actual mechanical conditions of the wrist by analyzing the subchondral mineralization. The aim of the present study was to evaluate the distribution of the subchondral bone mineralization of the distal radioulnar joint (DRUJ) noninvasively in living subjects by using computed tomography (CT) osteoabsorptiometry to gain new information about the long-term loading conditions.

Methods: Twenty-two wrist joints were investigated in 11 healthy young subjects by means of CT osteoabsorptiometry.

Proposed new method for angiographically quantifying neovascularization in prefabricated flaps.

Prefabricated flaps have many potential applications in plastic and reconstructive surgery. Despite numerous experimental investigations and clinical applications, a standard quantification procedure for analyzing neovascularization in prefabricated flaps has not yet been established in the literature. In this study, we developed a new method for quantifying neovascularization, using a standard integral line plate including 25 evenly spaced lines corresponding to a 15-cm flap length, which was subsequently analyzed under a 2x magnification loupe.
