- Tratamento cirúrgico de hemangioma infantil nasal e labial na fase involuída: relato de caso(2020) MENDES, MONIQUE; LOBATO, RODOLFO COSTA; ISHIDA, LUIZ CARLOS; GEMPERLI, ROLFABSTRACT Infantile hemangioma (IH) is the most common vascular tumor and the most frequent benign neoplasm in childhood, with the highest incidence in females and the white population. Almost 60% of cases occur in the head and neck, and active treatment during the proliferative phase is the most frequently indicated, due to possible functional problems and disfiguring potential. We report a case of a patient with involute infantile hemangioma of the nasal tip and upper lip, treated expectantly during childhood, submitted to residual deformity correction with rhinoplasty techniques, associated with zetaplasty and upper lip grafting with good results and patient satisfaction.
- Detecção de trombose venosa em retalhos livres por medidas de glicemia capilar(2012) MILLAN, Lincoln Saito; ISHIDA, Luiz Carlos; CHOI, Esther Mihwa Oh; GIACCHETTO JUNIOR, Enio Cesar; WEI, Teng Hsiang; MATTAR JÚNIOR, Rames; FERREIRA, Marcus CastroBACKGROUND: Monitoring of free flaps after surgery is vitally important, especially in the first few hours because the timing of reoperation can determine flap salvage or loss. To date, no study has examined the decision to reoperate on a flap based on the objective measure of glycemia or a comparison between flaps that showed good outcomes and those that showed vascular damage. The objective of this study was to evaluate the validity of blood glucose measurements within the flap as a method for monitoring free flaps and to compare the efficacy of this method with that of clinical assessments. METHODS: The study was prospective, included 16 patients with free flaps, and was conducted from May 2012 to July 2012. A team of professionals not involved in the surgery evaluated capillary glycemia. Flaps were clinically evaluated during the immediate postoperative period, on ICU admission, at every 3 hours, and as needed. RESULTS: Of the 16 patients, 5 (31.3%) had venous thrombosis in the first 24 hours. Statistically significant differences were noted in capillary glycemia in patients with or without venous thrombosis in measurements obtained 6, 9, and 12 hours after surgery (P < 0.05). CONCLUSIONS: The measurement of capillary glycemia was not superior to clinical evaluation by an experienced professional for the detection of venous thrombosis within free flaps.
- Rinoplastia preservadora piezoelétrica: uma abordagem alternativa para tratamento de nariz bífido em fissura facial nº 0 de Tessier(2020) ISHIDA, LUIZ CARLOS; LOBATO, RODOLFO COSTA; LUITGARDS, BRUNO FERREIRA; CARVAS, MARCELO JOSÉ MONTEIRO; RODRIGUEZ, JUAN FELIPPE GUIMARÃES URCIOLI MOSQUERA DE; GEMPERLI, ROLFABSTRACT The bifid nose management in Tessier nº 0 facial cleft is controversial due to its characteristics, such as a wide bone vault, low dorsal height, excessive skin, soft tissues volume, and distant upper and lower lateral cartilages. Conservative rhinoplasty techniques, using piezoelectric instruments, can be a good option for the bifid nose treatment, as they preserve the roof and upper lateral cartilages and perform a more accurate osteotomy. We report the treatment of bifid nose in a 13-year-old boy with facial cleft No. 0, to whom was performed conservative rhinoplasty with the aid of piezoelectric material. Given the excess of skin and soft tissues, a completely external transcutaneous approach was chosen. For osteotomies, lateral fractures under direct piezo-assisted vision were performed to have better control of the bone vault narrowing. The upper lateral cartilages and the internal nasal valves were preserved and brought back to the midline with horizontal “U” sutures to obtain a projection of the cartilaginous vault. A large segment of skin and soft tissue was excised after narrowing the nasal vault. A year of follow-up shows a narrow bone pyramid, better projection, and tip definition, but persisting with a vertically short nose. Conservative rhinoplasty techniques, assisted by piezoelectrics, may be an option for bifid nose treatment, requiring long-term follow-up and a study with more cases.
- Análise morfométrica do lábio superior e da ação do envelhecimento(2013) LONGO, MARCO VINICIUS LOSSO; ISHIDA, LUIS HENRIQUE; FORTES, FERNANDO SARTOR GUIMARÃES; KASAI, KIRIL ENDO; ISHIDA, LUIS CARLOS; ALONSO, NIVALDO; FERREIRA, MARCUS CASTROABSTRACT Background: A pleasant smile depends on harmonious relationships between the teeth, gums, and lips. The present study measured upper lip changes related to ageing using a morphometric analysis. Methods: Fortysix Caucasian women at least 15 years of age were selected and divided into four groups: 15 - 30 years old, 31 - 45 years old, 46 - 60 years old, and > 60 years old. Frontal photographs with closed lips and parted lips were taken. The following measurements were performed: upper lip height, upper vermilion height in parted and closed lips positions, and exposure of the central upper incisors in the relaxed position. Results: Upper lip height increased with age. The average upper lip height in the closed lips position was 13.75 mm in the youngest age-range (15 - 30 years old). The upper lip height gradually increased with age until reaching an average of 19.24 mm was observed in the > 60 years old group. The opposite result was observed in upper vermilion height, which decreased with increasing age. The average vermilion height in the parted lips position was 7.09 mm in the youngest age-range (15-30 years old) and decreased to 4.58 mm in the oldest group (> 60 years old). Teeth exposure decreased with age. The average upper teeth exposure was 3.55 mm in the youngest group and decreased to 0.40 mm in the oldest group. Conclusion: The upper lip height increases, while the upper vermilion height and exposure of the upper teeth decrease with age.
- 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.

article 7 Citação(ões) na Scopus Evaluation of use of acrylic resin-based surgical guide in the function and quality of life provided by mandibular prostheses with microvascular free fibula flap: A four-year, randomized, controlled trial(2016) BRANDAO, Thais Bianca; VECHIATO FILHO, Aljomar Jose; RIBEIRO, Ana Carolina Prado; GEBRIM, Eloisa Maria Mello Santiago; BODARD, Anne-Gaelle; SILVA, Dorival Pedroso da; SANTOS-SILVA, Alan Roger; LSHIDA, Luiz Carlos; DIAS, Reinaldo BritoStatement of problem. The correct positioning of the microvascular-free fibula flap (MFFF) is essential for satisfactory mandibular reconstruction. However, the effect of acrylic resin-based surgical guides on prosthetic rehabilitations has not yet been properly investigated. Purpose. The purpose of this randomized clinical trial was to evaluate whether intraoral and extraoral acrylic resin-based surgical guides improve anatomic, functional, esthetic, and quality of life (QoL) results for dental prosthetic rehabilitation with MFFF. Material and methods. Participants subjected to mandibular reconstruction with MFFF were selected and randomly distributed into 2 groups, control (Co; using conventional surgery) and acrylic resin-based surgical guides (Sg). Functional parameters related to prosthetic rehabilitation and QoL were evaluated by interviews and an oral health impact profile (OHIP)-14 questionnaire. Functional parameters and questionnaire scores were subjected to statistical analysis: the likelihood ratio and the Fisher exact and Mann-Whitney U tests (alpha=.05). Results. Of 40 participants, 18 were rehabilitated, 10 with tooth-tissue-supported partial removable dentures and 8 with implant prostheses. In Sg, the study measured an enhancement in functional parameters and revealed a significant improvement in QoL (P=.020). Conclusions. The guides proposed directly improved mandibular reconstruction. Functional aspects may be improved by allowing good intermaxillary relationships and posterior dental rehabilitation. Functional success is directly dependent on soft tissue status and the quality of its reconstruction. Soft tissue evaluation is important before dental rehabilitation.- Ferreira-Ishida Technique: Spare Roof Technique B. Step-by-Step Guide to Preserving the Bony Cap While Dehumping(2022) FERREIRA, Miguel Goncalves; ISHIDA, Luiz Carlos; ISHIDA, Luiz Henrique; SANTOS, MarilineFor V-shaped nasal bones, the authors consider that ostectomy of the dorsal keystone area can be avoided, and this has led to the development of a new preservation technique: the spare roof technique B (or Ferreira-Ishida technique), where the bony cap is preserved. It includes six main steps, as follows. Step 1, draw on the surface of the skin the desired dorsal brow-tip aesthetic lines, the pyriform aperture, the rhinion, and the amount of triangular bone that has to be taken out to allow pushing-down the bony cap, and the transversal line in the beginning of the nasal hump. Step 2, release the upper lateral cartilages from the dorsal septum (""high septal strip""). Step 3, take out the amount of dorsal septum necessary to dehump. Step 4, perform the paramedian high parallel osteotomies exactly below the marked brow-tip dorsal aesthetic lines. Then, perform the second group of lower osteotomies, until the E-point, to achieve a triangular shape of bone in each side of the bony cap. Perform the ostectomy of the mentioned triangular areas. Release the lateral keystone area. Perform partial ultrasonic ostectomy endonasally, below the nasal bones, to promote the weakening of the transverse fracture line, in the sagittal plane just above the E-point. Push-down gently the rectangular bony cap with a Luc nasal forceps (19 cm) in a greenstick fashion. Perform lateral traditional osteotomies from high to low to high to narrow the bony bridge as much as is needed. Step 5, perform a regular L-shape Cottle septoplasty (if necessary). Step 6, suture the cartilaginous middle vault (upper lateral cartilages) to the dorsal aspect of the remaining septum.
