RESUMO

Three-dimensional (3D) surface imaging has found its place in aesthetic surgery globally. The first attempt to use 3D surface imaging technique in clinic was in 1944 by Thalmaan, who used stereo photogrammetry to examine an adult with facial asymmetry and a baby with Pierre Robin syndrome. Three-dimensional photography is becoming more common allowing for a more dynamic facial evaluation, although it is associated with increased cost.

RESUMO

Cosmetic rhinoplasty involves surgical manipulation of the nasal cartilages, nasal bones, lining mucosa and extracartilaginous soft. The nasal tip is a complex composite arrangement of tissues. These structures are responsible for creating individuality and asymmetries and for controlling nasal air entry and valving. Medical aesthetics involves filling relevant areas of the tip with hyaluronic acid to disguise grooves or soft defect contour defects. Standard tip surgery involves an open or closed approach. Manipulation of the flexible alar cartilage using intracartilaginous and interartilaginous sutures is preferable to resection, and alar base reduction is becoming more prevalent.

RESUMO

BACKGROUND: Recently there have been concerns raised about anaplastic large cell lymphoma (ALCL) associated with breast implants. OBJECTIVES: The main aim of this article was to review and analyze the published literature specifically for hematopoietic malignancies associated with breast implants and postulate a hypothesis for their etiology and pathogenesis. METHODS: The PubMed database was searched using key words "lymphoma" and "breast implants" for published papers and abstracts on implant-associated hematopoietic malignancies. RESULTS: The authors found 83 published cases reported of lymphomas associated with breast implants in the medical literature. The reported cases involved various subtypes of lymphomas and the majority were ALCL, of which 66 were confirmed as ALK negative; however there was no association with any particular type of implant. The more aggressive cases and reported low death rate appeared to be related to the presence of breast masses at the time of presentation rather than effusion. The remaining reports were occasional case reports of T-cell lymphoma, follicular lymphoma, marginal zone B-cell lymphoma, primary effusion lymphoma and lymphoplasmacytic lymphoma. CONCLUSIONS: Considering the many thousands of women that have breast implants every year; the compiled data show that there is a very small risk of developing lymphoma. Increased awareness of association between implants and ALCL is needed globally and prospective patients considering breast implants should be fully informed of the risk. As the behavior of ALCL in these cases was indolent as compared with other primary breast lymphomas, it could suggest an abnormal reactive process. LEVEL OF EVIDENCE: 3

RESUMO

Since the first description of "The free abdominoplasty flap for breast reconstruction" by Hans Holmstrom in 1979, [see Ref. 1] the use of lower abdominal tissue has revolutionised reconstruction of the breast. DIEP (deep inferior epigastric perforator) free flap offers an abundance of reconstructive material, aesthetically-pleasing results and limited donor site morbidity. We report our first case of breast reconstruction with what presently is known as DIEP flap, performed in 1991 at St. Andrew's Centre for Plastic Surgery and Burns in Essex, The United Kingdom and the recent follow up results. We also discuss the historical events surrounding the evolution of this unpublished case and other documented cases.

RESUMO

BACKGROUND: Polyurethane-coated conical implants were introduced by Silimed (US distributor: Sientra, Santa Barbara, California) in 2008 and offer an alternative to round or anatomically shaped implants. By their design and volume distribution, they naturally create central volume and give a reasonable fullness to the upper pole while lifting some ptotic breasts, thus avoiding the need for classical mastopexy. OBJECTIVES: The authors discuss the advantages of conical implants as an alternative to conventional silicone implants for women with breast ptosis. METHODS: In the 2-year period between December 2010 and December 2012, a consecutive series of 302 women underwent implant-based breast surgery procedures (236 primary augmentations, 59 revisions, and 7 mastopexy-augmentations) with conical polyurethane devices. Implant volumes ranged from 225 to 560 cc, with low- to medium-profile devices predominating. No extra-high-profile implants were used. Only 1 patient had a drain inserted on completion of a revision augmentation. RESULTS: There were no infections (0%) and no wound dehiscence (0%). Four cases required reoperation (1.3%). Patient satisfaction scores were universally high (average, 9.94/10). There have been no capsular contractures to date, but follow-up is short. CONCLUSION: The modern conical, polyurethane implant has many advantages over the conventional round or anatomically shaped implants and offers patients an ideal compromise between volume, natural upper pole fullness, and a lift without mastopexy scars.

RESUMO

UNLABELLED: Abdominoplasty is a surgical procedure designed to rejuvenate truncal aesthetics, in which restoring "normal" waistline definition is one of the most challenging elements. Advancement in surgical techniques is reducing surgical risk and improving aesthetic outcomes. In this study we adopted the "Brazilian" abdominoplasty technique, originally presented by Ramos at the International Society of Plastic Surgeons Meeting in Australia (2008). Waist definition is improved by medially advancing Scarpa's fascia and repairing any divarication of the rectus abdominis muscles before vertically reducing redundant skin. In our study we demonstrated the role of Scarpa's fascia as an important part of the superficial fascial system, which helps define waist contour. The technique we demonstrate shows improved contouring and waist definition with lower complication rates (by minimising dissection and dead spaces).

RESUMO

Surgeons are commonly confronted with breast contour deformities and defects that result from previous surgical interventions. These soft tissue deformities can be corrected by conventional reconstructive flap surgery using autologous tissue, but there can be donor site morbidity. Smaller volume replacement is possible using temporary fillers such as hyaluronic acid or polylactic acid, or by using 'permanent' fillers such as autologous fat, but large defects are notoriously difficult to fill and often the fillers resorb or migrate. The patient described in this case report had an exchange of polyurethane implant (PU) in the left breast and correction of a contralateral breast contour filling deformity. A left breast partial capsulectomy was performed after implant removal and the capsule graft was inserted into a predissected pocket where soft tissue augmentation was required. A biopsy from the PU capsule was reported to show a foreign body type giant cell reaction to PU material in a fibrous capsule, lined by synovial metaplasia. The post-operative result showed satisfactory soft tissue revolumisation. PU breast implant structured capsule has thus been used as filler to correct breast soft tissue deformity and contour defects. Clearly it may have a use in other anatomical sites.

RESUMO

BACKGROUND: Yannas and Burke developed the concept of the dermal regeneration template in the 1970s. It is now a widely accepted tool in the treatment of burns as well as in reconstructive surgery. METHODS: The authors present a previously published study of Integra used in 20 consecutive patients to reconstruct 30 anatomical sites and then analyze the histologic and clinical outcomes. Wound healing was evaluated by examination of weekly punch biopsy specimens with standard and immunohistochemical stains. Patient satisfaction was assessed using a visual analogue scale, and scar appearance was assessed using a modified Vancouver Scar Scale. RESULTS: Four distinct phases of dermal regeneration could be demonstrated histologically: imbibition, fibroblast migration, neovascularization, and remodeling and maturation. Full vascularization of the neodermis occurred at 4 weeks. Patients reported increased range of movement and improvement in appearance compared with their preoperative states. CONCLUSIONS: The color of the matrix reflected the stage of neodermal vascularization. No adnexa, nerve endings, or elastic fibers were seen in any of the specimens. The new collagen was histologically indistinguishable from normal dermal collagen. The authors also present their current protocol and experience with using Integra for a range of reconstructive procedures.

RESUMO

We report a head and neck full-thickness burn injury that was reconstructed with a tissue-engineered dermal template and then early implantation of microdissected hair follicles through the silicone epidermis 12 days after the burn injury. The treatment resulted in complete reepithelialization and a hair-bearing scalp without the need for a split-thickness skin graft. Restoration of the stem cell population, hair growth, and earlier reepithelialization were achieved using this novel micrografting technique, and histologic examination confirmed maturation of a normal skin type over the subsequent 2 years.

RESUMO

Integra dermal regeneration template (Integra Life Sciences, Plainsboro, N.J.) is an effective treatment for full-thickness burns. It can also be useful in contracture release procedures; however, the clinical utility of a dermal regeneration template in contracture release procedures has not been adequately characterized. In this multicenter investigation, the outcomes of release procedures incorporating a dermal regeneration template for 89 consecutive patients, who underwent a total of 127 contracture releases, were retrospectively evaluated. The procedures involved the application of Integra, which includes a temporary silicone epidermal substitute and an artificial dermal layer. After formation of a neodermis, the silicone layer is removed and replaced with an epidermal autograft. Data on patient and contracture site history, treatment methods, physician assessments of range of motion or function, patient satisfaction, recurrence, and adverse events were collected with a standardized questionnaire. Release procedures for the study patients involved the neck, axilla, trunk, elbow, knee, hand, and other anatomical sites. The mean postoperative follow-up period was 11.4 months. At 76 percent of the release sites, range of motion or function was rated as good (significant improvement in range of motion or function) or excellent (maximal range of motion or function possible) by physicians. Responding patients expressed satisfaction with the overall results of treatment at 82 percent of the sites. No recurrence of contracture at 75 percent of the sites was observed during follow-up monitoring. Patient age and prior surgical treatment at the site did not significantly affect the results of treatment. However, outcomes were superior at mature sites, i.e., those for which more than 12 months had elapsed since the original injury. Postoperative complications rarely necessitated regrafting. These results indicate that a dermal regeneration template provides a useful alternative technique for contracture release procedures. The study data indicate that this approach leads to favorable functional outcomes and a high rate of patient satisfaction. This modality also seems to be versatile, because a range of anatomical sites are amenable to treatment with a dermal regeneration template, regardless of prior surgical treatment, and both pediatric and adult patients respond well to this form of therapy. Furthermore, Integra confers functional and cosmetic benefits similar to those of full-thickness grafts but without comparable potential for donor-site morbidity.
