- Resultados da ressecção de hemangiomas infantis nasais em fase proliferativa: abordagem segura para os tumores centrais da face(2012) GOLDENBERG, Dov Charles; FERNANDES, Thadeu Rezende Rangel; HIRAKI, Patricia Yuko; SMANIOTTO, Pedro Henrique de Souza; MOURA, Tatiana de; FERREIRA, Marcus CastroBACKGROUND: Infantile hemangioma is the most common benign tumor in infancy and occurs most often in the cervicofacial region. Its course can be divided into 3 phases with frequent spontaneous regression. However, residual sequelae or anatomical structure deformities can occur. An early and definitive surgical approach aiming at good aesthetic results and anatomical preservation is indicated in such cases because of the localization of the nasal hemangiomas and their capacity to disfigure. This study analyzed the results of the definitive surgical approach for proliferative nasal hemangiomas according to an objective evaluation. METHODS: From 1997 to 2009, 20 patients suffering from nasal hemangiomas in the proliferative phase were treated surgically. The lesions were analysed according to the area affected and type of treatment. Complication rates and the need for additional procedures were analyzed. The aesthetic results were evaluated by independent evaluators. RESULTS: The lesions were localized in the tip of the nose in 50% of patients, dorsal area in 20%, all subunits in 15%, paranasal areas in 10%, and alar area in 5%. Resection was total and subtotal in 60% and 40% of the patients, respectively. The mean follow-up period was 42.6 months. The mean number of surgical procedures per patient was 1.3 ± 0.7. No significant complications were observed. The results were positively evaluated with respect to the reduction of lesion volume and improved face shape, corroborating the proposed approach. CONCLUSIONS: Definitive surgical treatment is a safe and effective alternative for the management of nasal hemangiomas and has low complication rates.

- Surgical Treatment of Extracranial Arteriovenous Malformations after Multiple Embolizations: Outcomes in a Series of 31 Patients(2015) GOLDENBERG, Dov C.; HIRAKI, Patricia Y.; CALDAS, Jose Guilherme; PUGLIA, Paulo; MARQUES, Tatiana M.; GEMPERLI, RolfBackground: Surgical resection after embolization is the most accepted approach to treating arteriovenous malformations. The authors analyzed the outcome of surgically treated patients and how surgical resection was influenced by multiple embolizations. Methods: Thirty-one patients were included from January of 2000 to December of 2012. The mean patient age was 24.9 years. Anatomical involvement, definition of limits, functional impairment, number of embolizations, type of resection, reconstruction method, blood transfusion, and hospital stay were evaluated. Morbidity, mortality, and regrowth rates and need for additional procedures were evaluated. Results: Lesions were preferentially located at the orbits, cheeks, and lips. The number of embolizations per patient increased with lesion complexity. In 22 cases, total excision was accomplished, and in nine, subtotal resections were performed to favor function. After multiple embolizations, better lesion identification was observed. Primary closure was performed in 20 cases, local flaps were performed in seven cases, axial flaps were performed in two patients, and free flaps were performed in two cases. There were no deaths. Regrowth rates were influenced by limits between arteriovenous malformations and surrounding tissues (15.8 percent of cases with precise limits versus 58.3 percent of lesions with imprecise limits; p = 0.021) and by type of resection (18.2 percent of cases after total resection versus 66.7 percent after subtotal resections; p = 0.015). Conclusions: Multiple therapeutic embolizations seem to increase safety in the treatment of arteriovenous vascular malformations and suggest an additional positive effect besides bleeding control. Preoperative definition of limits and establishment of conditions for total resection are critical to determine management and risk of regrowth.

- Congenital Midline Cervical Cleft and Thyroglossal Duct Fibrous Cord-Like, is There a Mixed Presentation?(2023) KRUSCHEWSKY, Leonardo de Souza; MATOS, Leandro Luongo de; ALONSO, Nivaldo; SEIDLER, Cariline da Silva; LISBOA, Sonyara Rauedys Oliveira; SILVA, Roberto Cintra Lomanto Santos; GOLDENBERG, Dov Charles; SILVA, Tatiana Valeria NovaisIntroduction:Congenital midline cervical cleft is a rare condition and is frequently misdiagnosed as thyroglossal duct cyst. Otherwise, the combination of congenital midline cervical cleft and thyroglossal duct fibrosis in the same patient is as rare as important to be registered with the intention to inform and offer specific managements details for the literature.Case Presentation:Eight-year-old boy with simultaneous congenital midline cervical cleft and a thyroglossal duct fibrosis. The anatomic, clinical, radiologic, and pathologic characteristics of the congenital midline cervical cleft are described as well as surgical technique for removal and repair with Z-plasty.Conclusion:Congenital midline cervical cleft is a rare condition and when diagnosed must be surgically treated as early as possible. Its differential diagnosis is a clinical challenge.
- Análise bibliométrica dos artigos publicados na revista brasileira de cirurgia plástica entre 2005 e 2012. Parte III: desenhos de estudo e níveis de evidência(2014) DENADAI, RAFAEL; GOLDENBERG, DOV; RAPOSO-DO-AMARAL, CASSIO EDUARDOABSTRACT Introduction: Bibliometric methods have been used to analyze study designs and levels of evidence of articles published in various periodicals. Such information does not exist in the field of Brazilian plastic surgery. This study aimed to evaluate the study designs and levels of evidence of articles published in the Brazilian Journal of Plastic Surgery (“Revista Brasileira de Cirurgia Plástica,” RBCP), the only Brazilian journal devoted exclusively to plastic surgery. Methods: Study designs and levels of evidence of articles published in the RBCP between 2005 and 2012 were bibliometrically and quantitatively analyzed. The articles published in two periods (2005- 2008 and 2009-2012) were compared, in order to characterize the evolution of the scientific production of the RBCP. Results: During the period analyzed, 603 scientific articles met the inclusion criteria. The overall analysis revealed a significant predominance of retrospective studies and articles with level of evidence III (p < 0.05). The comparison between the periods showed a significant increase (p < 0.05) in the proportion of case series and scientific articles with level of evidence IV (2005-2008 < 2009-2012), and a significant reduction (p < 0.05) in the proportion of articles with level of evidence V (2005-2008 > 2009-2012). Conclusion: This study showed that a predominance of retrospective studies and articles with level of evidence III published in the RBCP between 2005 and 2012.
- Assimetria mamária: revisão da literatura e nova proposta de classificação clínica(2020) FARIA, GLADSTONE EUSTÁQUIO DE LIMA; GOLDENBERG, DOV CHARLES; BOGGIO, RICARDO FROTAABSTRACT Breast asymmetry is a prevalent diagnosis that has several surgical modalities for its treatment. The correct diagnosis, taking into account the existing classification systems, is imperative for achieving the best results. The leading and most accepted proposals for the classification and treatment of breast asymmetries were raised through the literature review. These available classifications date from the 60s and 70s and need to be updated to the current clinical context. A more simplified and reproducible classification was proposed after a comprehensive literature review, considering the most frequent asymmetries in aesthetic plastic surgery offices, with their respective treatment guides. Five groups were created: 1 - hypotrophic breasts with volume asymmetry; 2 - hypotrophy with volume and contour asymmetry; 3 - normotrophic, ptotic breasts and with no desire to increase the volume; 4 - normotrophic, ptotic breasts and with a desire to increase the final volume; 5 - asymmetric and hypertrophic breasts. Based on the clinical findings, a treatment algorithm was created for each subtype of asymmetry, including in this arsenal, breast implants of different volumes, mastopexies, reduction mammoplasty, and fat grafting. It is important to emphasize that breast asymmetry is the rule and not the exception, therefore, it is a reason for patient dissatisfaction and a challenge for the plastic surgeon.
- Análise bibliométrica dos artigos publicados na revista brasileira de cirurgia plástica entre 2005 e 2012. Parte I: análise quantitativa de artigos, autores e distribuição geográfica(2014) DENADAI, RAFAEL; GOLDENBERG, DOV; RAPOSO-DO-AMARAL, CASSIO EDUARDOABSTRACT Introduction: Bibliometric indicators have been implemented in several national and international studies. However, there is no specific information about the scientific articles discussing plastic surgery in Brazil. This study therefore aimed to carry out a bibliometric analysis of articles published in the Brazilian Journal of Plastic Surgery (RBCP), the official journal of the Brazilian Society of Plastic Surgery. Methods: A bibliometric analysis using quantitative indicators of all articles published in the RBCP was performed to characterize the scientific results over a seven-year period (2005-2012) marked by major changes to the journal. All articles selected were analyzed individually, in order to collect data on article and author numbers, and their geographical distribution. Two periods (2005-2008 vs. 2009-2012) were considered for comparative analysis. Results: A total of 603 articles met the inclusion criteria. The average number of articles published per year and the number of authors per article were 75.38 ± 32.12 articles/year and 3.98 ± 2.01 authors/article, respectively. There was a significant increase (p < 0.05) in articles/year in 20092012 compared to the earlier time period. No significant variations were detected (p > 0.05) in the number of authors/article (2005-2008 = 2009-2012). Most articles came from Brazilian institutions (98.67%; p < 0.05), and the Southeast region (63.70%; p < 0.05) accounted for most of these publications. Conclusion: During the observation period, the number of scientific articles published in the RBCP increased, there was no change in the number of authors per paper, and there was a predominance of articles coming from the Southeast Brazil.
- Validation of Videoconference With Smartphones in Telemedicine Facial Trauma Care: Analysis of Concordance to On-Site Evaluation(2016) FONSECA, Alexandre Siqueira Franco; GOLDENBERG, Dov Charles; STOCCHERO, Guilherme Flosi; LUIZ, Arthur Vicentini Costa; GEMPERLI, RolfBackground The continental size of some countries and heterogeneous hospital network prevents patients who live in remote areas from getting adequate initial assessment of facial trauma. The authors present an alternative model for trauma assessment by videoconference via smartphones and analyze the concordance between telemedicine and face-to-face management. Methods Fifty patients with either a confirmed or suspected diagnosis of facial trauma were independently evaluated by 2 teams of physicians: Face-to-face and telemedicine-based. The face-to-face team attended patients at bedside (physical examination and computed tomography scan analysis). The telemedicine team consisted of a general surgery resident on duty in the emergency room and a plastic surgeon researcher remotely communicating via smartphones. Both teams answered a questionnaire, which contained data concerning patient's epidemiology, physical examination, computed tomography (CT) scan findings, and treatment option to be followed. Data were analyzed and compared regarding the similarity of answers. Results The sample studied was consistent with the literature, showing a predominance of young males. Traffic accidents and personal violence were the main causes of trauma. The concurrency of answers for physical examination findings was considered substantial ( = 0.720). For CT scan findings, it was almost perfect ( = 0.899); for defining the treatment option, it was almost perfect ( = 0.891). High concurrency of face CT scan findings was observed after we calculated the positive predictive value (89.9%), negative predictive value (99.3%), sensitivity (94.2%), specificity (98.8%), and accuracy (98.3%). Conclusions The proposed model to facial assessment trauma by videoconference via smartphones is feasible, showing high concordance level with face-to-face assessment.
- Surgical Treatment of Facial Infantile Hemangiomas: An Analysis Based on Tumor Characteristics and Outcomes(2016) GOLDENBERG, Dov C.; HIRAKI, Patricia Y.; MARQUES, Tatiana Moura; KOGA, Andrea; GEMPERLI, RolfBackground: Surgical treatment of infantile hemangiomas may interfere with patient appearance. The use of an algorithm is essential to select candidates. The objective of this study was to evaluate outcomes of surgical treatment based on tumor characteristics. Methods: Seventy-four patients were treated surgically between 1997 and 2010. Demographics, tumor characteristics, surgical approach, and outcomes were evaluated. Results: The female-to-male ratio was 5.7:1. Mean age and follow-up were 24 years and 33 months, respectively. Surgery was elective in 83.8 percent and emergent in 16.2 percent of patients. Most frequent locations were lips, nose, eyelids, and cheeks. Surgery was performed during the proliferative phase in 43 patients (58.1 percent), and growth-related deformity was the main indication. No significant association between sex and the presence of complications or treatment indication was observed. Patients who underwent emergency procedures were younger (p = 0.0031) and had a higher incidence of evolutional complications (p = 0.012). Also, they were more frequently operated on during the proliferative phase (p = 0.011). Favorable outcome of surgical treatment was observed in both simple and complex cases for facial contour, volume reduction, and need for reoperation. The best candidates for elective surgery were patients with localized eyelid, nasal, or lip hemangiomas, presenting growth-related deformities during the proliferative phase. For patients undergoing emergency procedures, the best candidates were nonresponders to pharmacologic therapy with segmental periorbital hemangiomas, treated by partial resection. Conclusions: A profile of patients and their specific surgical approach was established. Satisfactory results could be achieved following the proposed algorithm. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
