Uso do retalho tubular retroauricular para reconstrução da hélice e lóbulo da orelha

Defeitos de orelha são frequentes e de etiologias diversas. Ainda assim, a reconstrução de orelha permanece um desafio dentro da cirurgia plástica reconstrutiva, principalmente devido a anatomia e a escassez de tecido local. Embora pouco utilizado, o retalho tubular retroauricular se apresenta como alternativa para reconstrução da hélice e lóbulo. No presente estudo os autores descrevem a técnica operatória, bem como relatam um caso em que foi utilizado. Realizou-se uma avaliação do resultado operatório de quatro casos de reconstrução de orelha utilizando o retalho tubular retroauricular, através de questionários encaminhados para avaliadores leigos e cirurgiões plásticos. O resultado estético final foi classificado como bom ou excelente por 35% dos avaliadores leigos e 50% dos cirurgiões plásticos. Já o resultado operatório foi avaliado como bom ou excelente por 70% dos leigos e 80% dos cirurgiões plásticos. Os resultados permitem concluir que a técnica do retalho tubular retroauricular para reconstrução de defeitos da borda de hélice pode ser indicada, com resultados satisfatórios

Use of retroauricular tubular flap for ear helix and ear lobe reconstruction

Ear defects are frequent and result of many etiologies, even though ear reconstruction remains a challenge in plastic reconstructive surgery due to anatomy and local tissue paucity. Despite being rarely used, the tubular retroauricular flap presents as an alternative for helix and lobule reconstruction. In this article, the authors describe the operative technique and report a case in which it was used. Also, plastic surgeons and laypeople rated the operative results of four cases of ear reconstructions using the tubular retroauricular flap. The final esthetic result was rated as good or excellent by 35% of laypeople and 50% of plastic surgeons, whereas the operative result was rated as good or excellent by 70% of laypeople and 80% of plastic surgeons. Thereby the findings and authors’ experience, we can recommend the tubular retroauricular flap technique for reconstructing ear helix border defects

Evaluation of the use of tissue expander in a university service

Introduction: Tissue expansion is an important reconstruction method to solve defects such as burns and giant nevi or breast reconstruction. This article aims to report the experience of the Plastic Surgery Service of the Hospital de Clínicas of the Federal University of Paraná (UFPR) with the use of expanders. Methods: This is a retrospective, descriptive, and analytical study of patients who underwent tissue expansion for reconstructive surgery at the Hospital de Clínicas da UFPR, from January 2010 to December 2016. Results: 61 patients and 80 surgeries were analyzed, including re-expansion procedures. Age ranged from 2 to 73 years (mean 31). The majority of patients were female (83.6%), aged over 40 years, undergoing breast reconstruction treatment after radical mastectomy (36%). The complications observed in these patients were: signs of infection (14.7%), suture dehiscence (3.2%), seroma (3.2%), defect in the expander (3.2%), exposure of the expander (3, 2%), necrosis (1.6%) and signs of hypoperfusion (1.6%). Patients undergoing breast reconstruction had the highest number of complications (40.1%). Reexpansion was necessary for 37.7% of patients. Conclusion: The skin expansion technique is indicated for several pathologies' treatment. The tissue expansion procedure has high complication rates. Knowing the patient's profile, the main types of complications, and the factors associated with these complications can help prevent them

Adjuvant-induced autoimmune syndrome triggered by silicone breast implants: systematic review

Adjuvant-induced autoimmune syndrome (ASIA) and its diagnostic criteria were described by Shoenfeld in 2011, relating symptoms of autoimmunity to adjuvants, such as silicone, present in breast implants. This systematic review aimed to gather data from the literature on symptomatology, incidence and proposed treatments for ASIA caused by silicone breast implants (SBI). Searches were carried out in PubMed, LILACS, Embase and Cochrane databases, using the descriptors “Autoimmune Syndrome Induced by Adjuvants,” “Breast implant,” and “Silicone Implant Incompatibility Syndrome.” The search strategy generated 95 articles, of which 20 were included in the review. The authors suggest three main theories to explain the development of the syndrome: genetic predisposition, silicone bleeding and the formation of a periprosthetic capsule. The most frequently described clinical manifestations include chronic fatigue, arthralgia, myalgia, and cognitive and sleep disorders. There is no consensus on laboratory findings and associated risk factors; recent studies propose expanding the diagnostic criteria initially described. Adequate treatment remains controversial, ranging from medications to prosthesis explantation. Although the reviewed articles suggest the existence of ASIA related to SBI, its precise pathophysiology is unknown, the symptoms reported are nonspecific, and the time between exposure and the onset of manifestations is uncertain. This systematic review concludes that, to date, there is not enough scientific evidence to establish the causality of the development of adjuvant-induced autoimmune syndrome resulting from silicone breast implants
