- A clinical experience of the supraclavicular flap used to reconstruct head and neck defects in late-stage cancer patients(2012) ALVES, Helio R. N.; ISHIDA, Luis C.; ISHIDA, Luis H.; BESTEIRO, Julio M.; GEMPERLI, Rolf; FARIA, Jose C. M.; FERREIRA, Marcus C.The supraclavicular island flap has been widely used in head and neck reconstruction, providing an alternative to the traditional techniques like regional or free flaps, mainly because of its thin skin island tissue and reliable vascularity. Head and neck patients who require large reconstructions usually present poor clinical and healing conditions. An early experience using this flap for late-stage head and neck tumour treatment is reported. Forty-seven supraclavicular artery flaps were used to treat head and neck oncologic defects after cutaneous, intraoral and pharyngeal tumour resections. Dissection time, complications, donor and reconstructed area outcomes were assessed. The mean time for harvesting the flaps was 50 min by the senior author. All donor sites were closed primarily. Three cases of laryngopharyngectomy reconstruction developed a small controlled (salivary) leak that was resolved with conservative measures. Small or no strictures were detected on radiologic swallowing examinations and all patients regained normal swallowing function. Five patients developed donor site dehiscence. These wounds were treated with regular dressing until healing was complete. There were four distal flap necroses in this series. These necroses were debrided and closed primarily. The supraclavicular flap is pliable for head and neck oncologic reconstruction in late-stage patients. High-risk patients and modified radical neck dissection are not contraindications for its use. The absence of the need to isolate the pedicle offers quick and reliable harvesting. The arc of rotation on the base of the neck provides adequate length for pharyngeal, oral lining and to reconstruct the middle and superior third of the face.
- Analysis of the Strength of the Abdominal Fascia in Different Sutures Used in Abdominoplasties(2011) ISHIDA, Luis Henrique; GEMPERLI, Rolf; LONGO, Marco Vinicius Losso; ALVES, Helio Ricardo Nogueira; SILVA, Pedro Henrique Quintino da; ISHIDA, Luis Carlos; FERREIRA, Marcus CastroProtrusion of the abdominal wall secondary to abdominoplasty may occur in patients with weakness of the aponeurotic structures. The anterior layer of the rectus abdominis muscle consists of fibers that are transverse rather than vertical. Based on this anatomical feature, vertical sutures are suggested for the correction of diastasis recti, since they include a greater amount of fascial fibers and thus would be more resistant to tensile strength than horizontal ones. The anterior layers of the rectus abdominis muscles of 15 fresh cadavers were dissected. Two vertical lines were marked on each side of the linea alba, corresponding to the site where plication is usually performed in abdominoplasties. Three abdominal levels were evaluated: the supraumbilical, umbilical, and infraumbilical levels. A simple suture was placed in the vertical direction in one group and in the horizontal direction in the other group, at each of the three levels previously described. These sutures were connected to a dynamometer, which was pulled medially toward the linea alba until rupture of the aponeurosis occurred. The mean strength required to rupture the aponeurotic structures in which the vertical sutures had been placed was greater than for the horizontal ones (p < 0.0001). The vertical suture of the rectus abdominis sheaths was stronger than the horizontal suture because of the more transversal arrangement of its aponeurotic fibers. Thus, routine use of the vertical suture in plications of the aponeurosis of the rectus abdominis muscles is suggested.
- Translation, Cross-Cultural Adaptation and Linguistic Validation of the FACE-Q Questionnaire for Brazilian Portuguese(2019) BUSTILLO, Adriana Margarita Buelvas; LOBATO, Rodolfo Costa; LUITGARDS, Bruno Ferreira; CAMARGO, Cristina Pires; GEMPERLI, Rolf; ISHIDA, Luiz CarlosBackgroundPatient-reported outcomes measurement instruments (PRO) are a good way to measure results after aesthetic procedures. FACE-Q is a systematized and standardized PRO tool and was not available in Portuguese. MethodsThis cross-sectional study included four stages: translation of FACE-Q, backtranslation, testing in patients who underwent facial aesthetic procedures and review of the questionnaires between September and December, 2018. Guidelines merging WHO and ISPOR's rules were followed. ResultsTranslation was conducted by two translators, resulting in two versions, translation A and translation B, which were reconciled to generate the first Portuguese version. Reconciliation showed inconsistencies between TA and TB in 63% (n=222) of the 353 questions, which were solved by maintaining TA in 25% of cases (n=87), TB in 27% and a new version in 11% (n=40) of the questions. Backtranslation showed written differences with the original FACE-Q in 64 (22.7%) of the 353 question, but only one case of semantic difference, which was corrected resulting in production of the second Portuguese version. Seven patients with a mean age of 35.8years were interviewed to assess the difficulty in understanding the questionnaires. Four patients had no or minor difficulties understanding the questionnaire, and the other three had difficulties and suggested changes that led to a third Portuguese version. The third version was reviewed for grammar and spelling resulting in the final Portuguese version.ConclusionA Brazilian Portuguese version of the FACE-Q questionnaire was obtained maintaining equivalency with the source instrument. This will allow cross-cultural research and comparison of results between different studies.Level of Evidence VThis journal requires that authors assign a level of evidence to each article.
