The “arrow flap” technique in reduction mammaplasty: Combining short scars, narrow base, and high and persistent breast projection
No full textIntroduction: Breast reduction is one of the most common procedures performed by plastic surgeons worldwide. Despite that several techniques have been proposed for management of ptotic or hypertrophic breasts, most of them often deal with too large breast bases, poor breast projection, persistent “dog ears,” and a certain percentage of bottoming out. Lower-pole shaping of the breast remains one of the challenge of vertical mammoplasty. Materials and Methods: The authors report their 5-year-long experience with a modification of the vertical scar technique, the “arrow flap,” in which they harvest a double lateral glandular and cutaneous flap, to tighten and better shape the base of the breast and to improve the breast projection with a “double-bra” effect. From April 2015 to February 2019, 75 patients with moderate to severe macromastia/breast ptosis underwent bilateral reduction mammoplasty. Results: Postoperative outcomes showed an overall satisfactory results and low incidence of complications. Two patients presented with an asymmetry between the 2 breasts, and no nipple-areola complex necrosis occurred. One patient reported a wider vertical scar, whereas no bottoming out was observed. Conclusions: All patients reported a stable and durable projection of the breast, with pleasant cosmetic results. By combining short scars and narrow base, we can obtain a pleasant lower pole reshaping of the breast, even in that challenging cases of large and squared breast. The authors believe that this technique provides a useful surgical option, increasing the versatility of the superior pedicle vertical mammaplasty both for mastopexy and breast reduction, even in cases of severe macromastia

No full textAcellular dermal matrix for rhinophyma: Is it worth it? A new case report and review of literature
No full textIntroduction: nasal reconstruction after rhinophyma surgery could be challenging. In the last decade, some authors proposed the use of dermal substitutes, but only few case reports have been described throughout the Literature. Presentation of case: we described a new case of severe and disfiguring rhinophyma treated by total excision and a two-step reconstruction by using acellular dermal matrix and subsequent full-thickness skin graft. Despite an overall improvement of the nasal shape and a good functional recovery were observed after 12 months of follow-up, the aesthetic outcome was not satisfactory and the patient required further surgical revisions. Discussion: the use of ADMs in rhinophyma poses some important aspects to be discussed. The resorption rate of the matrix and retraction rate of the skin graft make the final thickness of the neodermis unpredictable. Moreover the location of phymatous lesions and the extent of the surgical removal may strongly impact the final aesthetic outcome, often leading to a multistep procedure and patient dissatisfaction. Conclusion: although we believe that ADM represents a simple and reliable alternative for surgical reconstruction after rhinophyma, basing on our clinical experience we suggested some important tips and tricks in order to avoid surgical revisions, and both surgeons and patients should be aware about the potential drawbacks of this technique
Reconstruction of full-thickness soft tissue defects with integra: Risk factors and treatment algorithm
No full textBackground: Despite the fact that dermal substitutes are widely used in reconstructive surgery, there have been no studies focused on predictors of complications or delayed matrix take. We propose an algorithm for management of soft tissue reconstruction with Integra dermal matrix, based on our 5-year-long clinical experience. Methods: An estimated 111 patients who underwent Integra reconstruction of full-thickness soft tissue defects of different anatomical sites and etiology were enrolled, and dichotomized in two groups according to complications. Participants were further studied according to the wound healing strategy: healing by secondary intention, skin graft (STSG), and flap surgery. A regression analysis was conducted in the whole sample to identify possible predictors of complications. Results: No significant differences according to complications were observed. The between-group statistical analysis showed significant differences in age, comorbidities, defect area, diagnosis, and defect site. The regression analysis revealed that the timing of split-thickness skin graft (STSG) was not influenced by age, comorbidities, body mass index (BMI), defect area, site, wound etiology, and risk factors in the subjects who underwent a two-step reconstruction. Healing by secondary intention is recommended for small post-oncological defects of the head, especially in elderly and multimorbid patients. Variables that may interfere with dermal substitutes' incorporation are independent of the timing of STSG placement; therefore, no predictors of complications or delayed matrix take were identified. Conclusions: Our findings showed that Integra can be used in a wide range of patients regardless of their general features, thus acting as a useful alternative to conventional reconstructive techniques in selected cases
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
