Application of modified inferior pedicle technique with inverted T pattern for severe breast hypertrophy / 中国修复重建外科杂志

Objective: To explore the effectiveness of modified inferior pedicle technique with inverted T pattern for severe breast hypertrophy. Methods: Between January 2016 and May 2017, 15 patients of severe breast hypertrophy had undergone breast reduction using inferior pedicle technique with inverted T pattern combined with dermal suspension sling technique. The patients were 20 to 49 years old, with an average age of 31.6 years. Body mass index ranged from 24.9 to 32.5 kg/m 2, with an average of 30.8 kg/m 2. Among them, 11 cases had a history of childbearing. The degree of breast ptosis was rated as degree Ⅱ in 6 cases and degree Ⅲ in 9 cases. The unilateral breast reduced 615 g on average (range, 480-1 050 g). Results: The skin flap necrosis at the "T" trilateral junction occurred in 3 cases, and healed after dressing changes. The incisions of 12 cases healed and no fat liquefaction, hematoma, or seroma occurred. The sensation of nipple and areola declined at early period after operation in 2 cases, and gradually recovered. All patients were followed up 6-18 months (mean, 13 months). The shapes of bilateral breasts and the height and symmetry of nipple-areolar complex were good, and no obvious scar was found. The effectiveness was evaluated by surgeon and showed that there were 12 cases with satisfactory breast shape and 3 cases with unsatisfactory breast shape; 3 cases with obvious scare and 12 cases with insignificant scar; 13 cases with normal nipple sensation and 2 cases with hypoesthesia; 11 cases with symmetric nipples and 4 cases with asymmetric nipples. The effectiveness was evaluated by patients and showed that the satisfactory breast shape in 10 cases, relatively satisfactory breast shape in 4 cases, and unsatisfactory breast shape in 1 case; highly acceptable scar in 9 cases, moderately acceptable scar in 4 cases, and unacceptable scar in 2 cases; overall satisfactory in 10 cases, relatively satisfactory in 4 cases, and unsatisfactory in 1 case, with the overall satisfaction rate of 93.3% (14/15). Conclusion: For severe breast hypertrophy, the modified inferior pedicle technique with inverted T pattern can obtain satisfactory appearance and avoid the mastoptosis.

Mamoplastias redutoras e mastopexias realizadas no HC-UNICAMP: análise comparativa entre duas técnicas / Reduction mammoplasties and mastopexies performed at HC-UNICAMP: comparative analysis between two techniques

Introdução: Diferentes técnicas para mamoplastia redutora e mastopexia são descritas na literatura, visando a resultados que reconstituam o polo superior, ofereçam melhor projeção e proporcionem tratamento adequado para a ptose mamária. No entanto, devemos nos atentar para a segurança da técnica, com manutenção da vascularização, inervação dos tecidos e possibilidade de amamentação. Análise comparativa com pacientes operadas pela técnica com retalho de pedículo inferior e pacientes operadas pela técnica com sutura circular em bolsa. Métodos: Análise de 85 pacientes submetidas à mamoplastia redutora ou mastopexia sem implantes, entre janeiro de 2011 e dezembro de 2012, no Hospital de Clínicas da Unicamp. Foram excluídos 31 pacientes, as quais foram submetidas apenas à mamoplastia redutora pela técnica de Pitanguy (sem utilização de retalhos ou sutura circular). Dentre as 54 pacientes restantes, cinco foram posteriormente excluídas devido ao não comparecimento à consulta ou à não realização da ultrassonografia pós-operatória. Foram agrupadas 16 pacientes submetidas à sutura circular contínua e 33 pacientes operadas pela técnica de pedículo inferior. Resultados: Dados demográficos foram semelhantes nos dois grupos. Maior número de pequenas complicações e resultados insatisfatórios foi observado no grupo submetido à técnica de pedículo inferior, bem como maior índice de achados ultrassonográficos relevantes no pós-operatório. Conclusão: A técnica de sutura circular contínua apresentou elevado índice de satisfação, menor número de complicações e resultados mais duradouros quando comparados com a técnica de pedículo inferior, durante o período analisado.

Introduction: Several reduction mammoplasty and mastopexy techniques are described in the literature, with the aim of reconstituting the upper pole, offering better projection, and providing adequate treatment for breast ptosis. However, particular attention should be devoted to the safety of the technique, with maintenance of vascularization, tissue innervation, and the capability of breastfeeding. Female patients operated on with the inferior pedicle flap technique were compared with those operated on with purse-string circular suturing. Methods: Eighty-five patients who had undergone reduction mammoplasty or mastopexy without implants, between January 2011 and December 2012 at Unicamp's Clinical Hospital, were evaluated. Thirty-one patients who only underwent reduction mammoplasty by Pitanguy's technique (without the use of flaps or circular sutures) were excluded. Of the remaining 54 patients, five were subsequently excluded for not attending medical appointments or failure to have postoperative ultrasonography. A group of 16 patients who had undergone circular suturing and a group of 33 operated on by the inferior pedicle technique were considered. Results: Demographic data were similar for both groups. A higher number of minor complications and unsatisfactory results were observed in the group that underwent the inferior pedicle technique, who also had a higher rate of relevant post-operative ultrasonography events. Conclusion: The circular suturing technique resulted in a high satisfaction rate, lower number of complications, and longer lasting results than the inferior pedicle technique, during the period analyzed in this study.

Aplicação estética e reconstrutora da mamoplastia com pedículo areolado / Aesthetic and reconstructive application of mammoplasty with the inferior dermal pedicle technique

Introdução: A mamoplastia redutora é uma das mais frequentes cirurgias realizadas no âmbito da cirurgia plástica, sendo que diversas técnicas são descritas. A técnica do pedículo inferior areolado é uma técnica pouco difundida no Brasil, que pode ter aplicação tanto em cirurgias estéticas quanto reconstrutoras. O objetivo deste estudo foi analisar os resultados de mamoplastias realizadas com esta técnica. Métodos: Análise retrospectiva de prontuários, contato telefônico com as pacientes e análise fotográfica, identificando perfil das pacientes, finalidade da cirurgia, complicações, grau de satisfação e grau de sensibilidade do complexo aréolo-papilar (CAP). Resultados: No período analisado, 74 pacientes foram submetidas à mamoplastia com a técnica do pedículo inferior areolado (42 mamoplastias redutoras estéticas, 13 mamoplastias para reconstrução imediata de mama pós-ressecções segmentares, e 19 mamoplastias de simetrização pós-reconstrução com outras técnicas). Complicações ocorreram em 20 pacientes. Em relação à avaliação da satisfação pelas pacientes, o resultado foi considerado ótimo em 62,16% dos casos, bom em 25,67%, e regular em 12,17%. Quanto à sensibilidade do CAP, 72,97% das pacientes referiram não haver perda da sensibilidade, 20,27% referiram pequena diminuição, 6,76% referiram diminuição significativa e nenhuma relatou perda total da sensibilidade. Conclusões: A técnica de mamoplastia redutora com pedículo inferior areolado apresenta boa aplicabilidade, tanto em cirurgias estéticas quanto reconstrutoras, seja em reconstruções imediatas (quadrantectomias superiores) ou em simetrizações, principalmente pós TRAM. Apresenta alto grau de satisfação com o resultado, baixa taxa de complicações, alta preservação da sensibilidade do CAP e boa manutenção do resultado.

Introduction: Reduction mammaplasty is one of the most common surgeries performed in the field of plastic surgery, and several techniques have been described. The inferior dermal pedicle technique, which is relatively unknown in Brazil, may have applications in both aesthetic and reconstructive surgery. The aim of the current study was to analyze the results of mammaplasty performed with this technique. Methods: Data were collected from a retrospective analysis of medical records. Study data also included data obtained through telephone contact with patients, photographic analysis, and patient profiles, as well as data on the purpose of the surgery, complications, satisfaction with results, and degree of sensitivity of the nipple-areolar complex (NAC). Results: During the study period, 74 patients underwent mammaplasty with the inferior pedicle technique (42 aesthetic reduction mammaplasties, 13 mammaplasties for immediate breast reconstruction following segmental resections, and 19 post-reconstruction symmetrization mammaplasties with other techniques). Complications occurred in 20 patients. Regarding the assessment of satisfaction by the patients, the outcome was rated as excellent in 62.16% of cases, good in 25.67%, and fair in 12.17%. In terms of the sensitivity of the NAC, 72.97% of patients reported no loss of sensitivity, 20.27% reported a small loss, 6.76% reported significant loss, and no patients reported a total loss of sensitivity. Conclusions: The inferior pedicle reduction mammaplasty technique has good applicability both in aesthetic reconstructive surgeries and in immediate reconstructions (upper quadrantectomies) or symmetrizations, especially after the use of a transverse rectus abdominis myocutaneous flap. The technique offers a high degree of satisfaction with the results, a low rate of complications, a high degree of preservation of the sensitivity of the NAC, and good maintenance of the results.
