- 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.
