Tratamento da flacidez músculo aponeurótica acentuada da parede abdominal, experiência de 26 anos / Treatment of marked abdominal wall musculoaponeurotic flaccidity: 26 years of experience

Realizamos uma análise de quais são os elementos responsáveis pelo sustento e formato abdominal, determinando assim, que é devido a uma excessiva flacidez musculoaponeurótica de origem primária, à qual promove uma incapacidade do suporte da parede abdominal e pode estar relacionada a fatores predisponentes. Para esses casos específicos, desenvolvemos um tratamento propondo a colocação da tela e apresentando nossa experiência. Apresentamos esta série de casos de experiência em 26 anos. Onde 15 pacientes foram tratados com abdominoplastia primária e secundária. O reforço da parede abdominal foi realizado através da colocação de tela de polipropileno no plano submuscular com pontos em U na fáscia transversalis, buscando-se fortalecer o músculo e a fáscia transversa. Os resultados foram satisfatórios a longo prazo. Obtendo resolução das protuberâncias abdominais e restaurando a harmonia dos músculos. Apenas duas complicações ocorreram, que foram a presença de dor crônica localizada no abdome tratada com infiltrações de esteroides e fístula umbilical precoce de resolução rápida espontânea, independente da proposta.

We investigated the causative factors of abdominal support and shape and found that excessive musculoskeletal flaccidity of primary origin causes an inability to support the abdominal wall and may be associated with the predisposing factors. For such cases, we developed a treatment consisting of the placement of a subcutaneous mesh. Here, we present our experience with this treatment. We present a case series of 15 patients in our 26 years of experience who were treated with primary and secondary abdominoplasties. The abdominal wall was reinforced by placing a polypropylene mesh in the submuscular plane with U-stitches in the transversalis fascia, aiming at strengthening the muscle and transverse fascia. The results were satisfactory in the long term. Abdominal bulges were repaired, and muscle harmony was restored. Only two complications occurred: chronic pain localized in the abdomen, which was treated with steroid infiltrations, and an early umbilical fistula with spontaneous and rapid resolution, regardless of the proposal.

Comparative Analysis of Phase Lag Entropy and Bispectral Index as Anesthetic Depth Indicators in Patients Undergoing Thyroid Surgery with Nerve Integrity Monitoring

BACKGROUND: Most depth of anesthesia (DOA) monitors rely on the temporal characteristics of a single-channel electroencephalogram (EEG) and cannot provide spatial or connectivity information. Phase lag entropy (PLE) reflects DOA by calculating diverse connectivity from temporal patterns of phase relationships. The aim of this study was to compare the performance of PLE and bispectral index (BIS) monitors for assessing DOA during anesthesia induction, nerve integrity monitoring (NIM), and anesthesia emergence. METHODS: Thirty-five patients undergoing elective thyroid surgery with recurrent laryngeal nerve NIM received propofol and remifentanil via target-controlled infusion. After applying PLE and BIS monitors, propofol infusion was initiated at a calculated effect site concentration (Ce) of 2 µg/mL and then increased in 1-µg/mL Ce increments. After propofol Ce reached 5 μg/mL, a remifentanil infusion was begun, and anesthesia induction was considered complete. During NIM, PLE and BIS values were compared at a specific time points from platysma muscle exposure to subcutaneous tissue closure. PLE and BIS values were recorded continuously from preanesthetic state to full recovery of orientation; bias and limits of agreement between monitors were calculated. RESULTS: PLE and BIS values decreased progressively with increasing propofol Ce during anesthetic induction and increased by stages during emergence. The prediction probabilities of PLE and BIS for detecting propofol Ce changes were 0.750 and 0.756, respectively, during induction and 0.749 and 0.746, respectively, during emergence. No aberrant PLE or BIS values occurred during NIM. Correlation coefficients for BIS and PLE were 0.98 and 0.92 during induction and emergence, respectively. PLE values were significantly higher than BIS values at full recovery of orientation. Estimated bias between monitors was −4.16 ± 8.7, and 95% limits of agreement were −21.21 to 12.89. CONCLUSION: PLE is a reasonable alternative to BIS for evaluating consciousness and DOA during general anesthesia and during NIM.

Injertos de Recubrimiento en Rinoplastia Una nueva propuesta / Nasal autologus grafts in Rinoplasty A new propousal

El objetivo de este artículo es exponer nuestra experiencia en el uso de injertos de recubrimiento para la punta y el dorso nasal. Se mostrará detalladamente la técnica quirúrgica por medio de un abordaje abierto y una serie de 59 pacientes en quienes se colocaron injertos de recubrimiento obtenidos del SMAS (sistema músculo aponeurótico superficial) y su seguimiento. Esta técnica no descrita previamente se presenta como una alternativa que podría ser de utilidad para los otorrinolaringólogos y cirujanos plásticos faciales. La principal ventaja que ofrece esta técnica, es la prevención de retracciones y favorecer el camuflaje de los injertos nasales, especialmente postes y escudos bajo pieles delgadas, con el fin de obtener resultados más naturales y consistentes a largo plazo.

The aim of this article is to present our experience in the use of coverage grafts for the tip and dorsum of the nose. A detailed description of the technique is shown, via an open rhinoplasty approach. Selected cases, in which a graft harvested from the SMAS (nasal superficial musculoaponeurotic system) was used, are depicted for pre and postoperative comparison. This technique is suggested as a useful surgical alternative for otolaryngologists and facial plastic surgeons. The main advantages of this technique is the prevention of retractions and an appropriate camouflage of nasal grafts, especially struts and shields underlying thin nasal skin, in order to achieve more natural and aesthetic results, consistent in the long term.

A Novel Approach to Submandibular Gland Ptosis: Creation of a Platysma Muscle and Hyoid Bone Cradle

Submandibular gland ptosis is a common impediment to obtaining superior surgical aesthetic results in neck lift surgery. Techniques for suspending the submandibular gland have been proposed, but these procedures have the drawbacks of disturbing the floor of the mouth mucosa and periosteum. We present an approach of submandibular gland suspension for the treatment of gland ptosis by employing a platysma and hyoid bone fascia cradle. Our technique was performed on cadaveric models. The platysma muscle and hyoid bone cradle for submandibular gland ptosis was created on the left side of the neck in two cadavers. A submental incision with sharp dissection was performed to raise a supraplatysmal flap. A subplatysmal plane was developed until the submandibular gland was identified. Sutures were used to pexy the platysma to the hyoid bone periosteum and deep cervical fascia, tightening the overlying muscle and in turn elevating the submandibular gland. Submandibular gland ptosis must be corrected in order to achieve exemplary aesthetic results. Our approach of creating a cradle with the platysma and hyoid bone avoids the potential complications of previously described sling procedures, while still maintaining the integrity of the gland and surrounding tissues.

Individualized Considerations Regarding Sub-Superficial Musculoaponeurotic System Facelift Techniques

Based on a thorough understanding of facial structure around the superficial musculoaponeurotic system (SMAS), some types of sub-SMAS techniques have emerged to allow more harmonious rejuvenation procedures in the lower face and midface. These techniques are the Hamra composite facelift, the Stuzin extended SMAS technique, the Barton high SMAS technique, and the Ramirez subperiosteal facelift, each of which involves a specific dissection plane and is informed by distinct rationales with reasonable support. Each patient presents a unique facial structure and undergoes an individual rate of aging. The facial structures of East Asian faces, in particular, differ from those of Western faces. While emphasizing that the theory of structural mid-cheek anatomy is an essential part of facial rejuvenation, we would like to discuss the advantages and disadvantages of various sub-SMAS facelift techniques and to propose the most suitable techniques for a variety of individual faces.

Surgical strategy for postburn cervical scar contracture / 中华烧伤杂志

<p><b>OBJECTIVE</b>To explore the surgical strategy for postburn cervical scar contracture.</p><p><b>METHODS</b>Sixty-five patients with scar contracture as a result of burn injury in the neck were hospitalized from July 2013 to July 2014. Release of cervical scar contracture was conducted according to different demands of the 3 anatomic subunits of neck, i.e. lower lip vermilion border-supramaxillary region, submaxillary region, and anterior region of neck. After release of contracture, platysma was released. For some cases with chin retrusion, genioplasty with horizontal osteotomy was performed. The coverage of wound followed the principle of similarity, i.e. the skin tissue covering the wound in the neck should be similar to the characters of skin around the wound in terms of color, texture, and thickness. Based on this principle, except for the preschool children in whom skin grafting was performed, the wounds of the other patients were covered by local skin flaps, adjacent skin flaps, or free skin flaps.</p><p><b>RESULTS</b>All patients underwent release of scar and platysma, while 9 patients underwent genioplasty with horizontal osteotomy. Wounds were covered with local skin flaps in 32 patients, with adjacent skin flaps in 7 patients, with free skin flaps in 11 patients, and with skin grafts in 15 patients. All skin grafts and flaps survived. Good range of motion was achieved in the neck of all patients, with the cervicomental angle after reconstruction ranging from 90 to 120°. All patients were followed up for 6 to 24 months. Six patients who had undergone skin grafting were found to have some degrees of skin contracture, while none of the patients who had undergone flap coverage showed any signs of contracture recurrence.</p><p><b>CONCLUSIONS</b>Restoration of the cervicomental angle is critical in the treatment of postburn cervical scar contracture, and the release of scar contracture should conform to the subunit principle. The coverage of wound should be based on the principle of similarity, with repair by skin flaps as the first choice, and skin grafting as the second choice. Satisfactory effect of repair would be achieved by following the above surgical principles.</p>

Método de avaliação da suspensão do SMAS no rejuvenescimento facial / A method to evaluate the SMAS suspension in facelift

INTRODUÇÃO: A suspensão do sistema musculoaponeurótico superficial (SMAS) é um procedimento amplamente aceito nas ritidoplastias. Com o objetivo de avaliar a eficácia de tal suspensão na técnica de tratamento do SMAS em round block com cicatrizes curtas, foi proposto método em que a redução da área descolada é avaliada ao final da cirurgia, assegurando sua eficácia, baseada em clara evidência. MÉTODO: Foram analisadas 20 cirurgias consecutivas de ritidoplastia, todas realizadas pelo mesmo cirurgião, com os mesmos padrões. Foram tomadas 12 medidas em cada lado da face, 7 antes e 5 após a realização da suspensão, permitindo a elaboração de 40 diagramas compreendendo as áreas avaliadas antes e após o procedimento. Foi utilizado o software ImageJ (NIH Image) para cálculo das áreas. RESULTADOS: A área descolada nas 40 medidas apresentou média de 52,6 cm², mudando para 32,6 cm² após a suspensão, com redução média de 38%. Os diagramas obtidos refletiram a exata atuação nos diversos pontos da face. CONCLUSÕES: O método descrito confirma que a técnica é eficiente quanto à suspensão do SMAS, com redução significativa da área descolada e consequente diminuição do espaço morto pós-operatório, e pode servir como parâmetro para comparação de diferentes técnicas.

BACKGROUND: The superficial musculo-aponeurotic system (SMAS) suspension is a globally accepted procedure in rhytidoplasties. In order to evaluate the efficacy of suspension performed with the round block SMAS treatment, the authors planned a method in which the wound area reduction is measured to assure its functionality, based in clear evidence. METHODS: Twenty consecutive rhytidoplasties were evaluated, all of them done by the same surgeon, using the same standards. Twelve measures were taken in each side of the face, 7 before suspension and 5 after, allowing for the elaboration of 40 diagrams comprising the areas evaluated before and after suspension. The software ImageJ (NIH Image) was used to evaluate the surfaces. RESULTS: The undermined area in the 40 measures had a mean of 52.6 cm², which changed to a mean of 32.6 cm² after suspension, with a mean reduction of 38%. The diagrams also showed the exact handled points of the face. CONCLUSIONS: The described methodology confirms that the round block SMAS treatment technique is efficient regarding the suspension of the superficial muscular aponeurotic system, with significant reduction of the undermined area, consequently reducing the dead space, and may be a parameter to comparison of different techniques.

Minimally invasive lift of the middle third of the face using musculoaponeurotic suspension with periosteal fixation technique: a review of 50 cases / Suspensão musculoaponeurótica com fixação periostal minimamente invasiva do terço médio da face: revisão de 50 casos

BACKGROUND: At present, demanding workplaces in our society cause patients to search for less invasive procedures with diminished morbidity and more rapid healing to meet their cosmetic requirements. A combination of several new noninvasive procedures allows significant facial changes, achieving a youthful and healthy appearance without traditional surgical procedures. OBJECTIVE: The purpose of this study is to describe the minimally invasive lift of the middle third of the face using a musculoaponeurotic suspension with periosteal fixation technique. METHODS: Fifty patients (age, 39 to 68 years; all female) who underwent an operation from December 2008 to June 2010 were enrolled in this study. The patients underwent a minimally invasive facelift technique for the middle third of the face, based on a thread lift of the temporal region and musculoaponeurotic suspension with periosteal fixation, inside the hairline. RESULTS: During the follow-up period of up to 18 months after the procedure, satisfactory results were observed. The patient satisfaction degree, especially in the first 6 months after the procedure, was extremely high (88 percent). CONCLUSIONS: The procedure offers good and immediate results, without incisions or a recovery period. The association of this procedure with other procedures is a good option for patients who cannot undergo or do not want to undergo traditional surgical procedures. The procedure is very different from current techniques that use threads because the suspension is musculoaponeurotic and does not invade the face. Therefore, morbidity and recovery time are decreased.

INTRODUÇÃO: Na sociedade atual, em decorrência das demandas profissionais, os pacientes cada vez mais procuram por procedimentos menos invasivos, com baixa morbidade, rápida recuperação, e que atendam a suas preocupações estéticas. Uma combinação de vários novos procedimentos não-invasivos permite mudanças faciais significativas e aparência jovem e saudável, sem a utilização de procedimentos cirúrgicos tradicionais. OBJETIVO: O objetivo deste estudo é a descrição de técnica de suspensão musculoaponeurótica com fixação periostal minimamente invasiva do terço médio da face. MÉTODO: Foram incluídos nesse estudo 50 pacientes, com idades entre 39 anos e 68 anos, todos do sexo feminino, operados no period de dezembro de 2008 a junho de 2010. As pacientes foram submetidas à realização de facelift minimamente invasivo do terço médio da face, com suspensão musculoaponeurótica com fixação periostal, baseado na tração com fio passado na região temporal, dentro da área do cabelo. RESULTADOS: No acompanhamento das pacientes, até 18 meses após a realização do procedimento, verificaram-se resultados satisfatórios. O grau de satisfação das pacientes com os resultados obtidos, principalmente nos primeiros seis meses após a realização do procedimento, foi extremamente alto (88 por cento). CONCLUSÕES: O procedimento ofereceu bons e imediatos resultados, sem incisões ou período de recuperação. Associado a outros procedimentos de rejuvenescimento facial, trata-se de boa opção a pacientes que não podem ou não querem se submeter a procedimentos cirúrgicos tradicionais. O procedimento difere significativamente das técnicas atuais que usam fios, pois a suspensão é musculoaponeurótica e não invade a área da face, o que diminui a morbidade e o período de recuperação.
