Uso de ácido tricloroacético para fechamento de lesão por alargadores em lóbulos de orelhas / Use of trichloroacetic acid for closure of lesion by extensors in lobules of ears

Introdução: O uso de alargadores de lóbulos de orelhas provoca um defeito circular cujo fechamento se torna um desafio para o cirurgião plástico. Existem múltiplas técnicas com mobilização de retalhos locais na tentativa de promover o fechamento e devolver o formato natural do lóbulo. Nossa proposta é apresentar o ácido tricloroacético (ATA) como alternativa para a correção dessas lesões. Métodos: Foram selecionados um total de 5 pacientes com lesões por alargadores nos lóbulos das orelhas e utilizado ATA 90% para o fechamento dos defeitos. Resultados: Após a aplicação do produto, observouse uma hiperemia ao redor da área onde foi aplicado o ácido nos primeiros dias, a área de frosting foi substituída por uma crosta, que foi se soltando com o passar dos dias, concomitante a redução do diâmetro da lesão com fechamento progressivo do defeito. Conclusão: Apesar de mais estudos serem necessários, a utilização de ATA 90% se mostrou uma opção simples e eficaz para o fechamento de lóbulos de orelhas alargados.

Introduction: The use of ear lobe extenders causes a circular defect whose closure becomes a challenge for the plastic surgeon. There are multiple techniques with mobilization of local flaps in an attempt to close and return to the natural shape of the lobe. We propose to present trichloroacetic acid (TCA) as an alternative for the correction of these lesions. Methods: A total of five patients with lesions by ear skin eyelets were selected, and 90% TCA was used to close the defects. Results: After applying the product, in the first days, there was a hyperemia around the area where the acid was applied. The frosting area was replaced by a crust, which loosened over the days, concomitantly reducing the diameter of the lesion with progressive closure of the defect. Conclusion: Although more studies are needed, the use of 90% TCA proved to be a simple and practical option for the closure of enlarged ear lobes.

Use of an Osteoplastic Flap for the Prevention of Mastoidectomy Retroauricular Defects

Abstract Introduction After mastoidectomy, patients usually complain of bone depressions in the retroauricular region in the surgical site, especially in procedures that require extensive cortical resections. This causes inconveniences such as difficulty wearing glasses, cleaning, and aesthetics complaints. Objective This study aims to describe a vascularized flap surgical technique that uses the mastoid cortical bone adhered to the periosteum, which is pedicled on the anterior portion and repositioned at the end of the surgery. This ensures the coverage of the mastoid cavity generated by surgery and prevents ear retraction into the cavity. This preliminary report describes the technique and intraoperative and immediate postoperative complications. Methods After retroauricular incision, periosteal exposure is performed. A U-shaped incision is required for the procedure and delimits a periosteum area appropriate to the size of the mastoidectomy. The cortical bone is opened using a 2.5 mm drill around the perimeter of the "U," at a 3 mmdepth. A chisel is introduced through the surface cells of the mastoid, and a hammer evolves into the anterior direction. The flap is lifted, leaving the periosteum adhered to it and forming a cap. The flap is anteriorly fixed to not hinder the surgery, and repositioned at the end. The periosteum is then sutured to the adjacent periosteum. Results The first 14 cases had no intraoperative complications and were firm and stable when digital pressure was applied during the intraoperative and immediate postoperative periods. Conclusion The osteoplastic flap pedicle is a safe and simple procedure, with good results in the immediate postoperative period.

The implantation of Bonebridge in bilateral congenital malformation of external and middle ear / 中华耳鼻咽喉头颈外科杂志

Objective@#To evaluate the auditory efficacy of Bonebridge implantation in patients with bilateral congenital malformation of external and middle ear.@*Methods@#Eleven cases (6 males and 5 females) had unilateral Bonebridge implantation. The age ranged from 8 to 26 and the average age was 16.9. Seven to ten days after operation, the first fitting was undergone. In acoustic sound field, the average auditory thresholds were respectively measured for unaided ears and Bonebridge implanted ears by pure tone auditory (PTA, 0.25, 0.5, 1, 2 and 4 kHz). For the group over 12-year-old, MSTM was applied to evaluate speech discrimination score (SDS). For the other cases, MLNT was used as the test material. The auditory efficacy post Bonebridge implantation would be analyzed and evaluated by comparing the differences between unaided ears and Bonebridge implanted ears.@*Results@#The bone conduction audibility threshold after Bonebridge implantation was as well as the preoperative. The auditory threshold with Bonebridge aided was improved to 25-35 dB HL, when compared to that of the unaided ears in the sound field. The SDS in the group over 12-year-old was improved about 50%; the efficacy was slightly limited for the other two cases (both less than 12 years old). Statistical analysis showed that there were significant differences between unaided ears and Bonebridge implanted ears in the sound field and SDS(P<0.05).@*Conclusions@#The auditory efficacy of Bonebridge is significant and noticeable in patients with bilateral congenital malformation of external and middle ear. Bonebridge provides a new and effective way for patient with congenital malformation of external and middle ear to reconstruct hearing.

Manejo da deformidade auricular de Stahl: um relato de caso / Management of Stahl's ear: a case report

Descrita no século XIX, a deformidade auricular de Stahl consiste em uma má formação auricular rara, caracterizada por hipoplasia da raiz da anti-hélice com o alargamento de sua base e uma terceira raiz da anti-hélice conectando-a à parte posterior da hélice, deformando a porção posterossuperior do pavilhão auditivo. A correção cirúrgica é o tratamento definitivo, porém, pela diversidade de apresentações clínicas, não há uma técnica padrão para todos os casos. O método descrito neste relato é mais uma opção de tratamento e consiste na ressecção da terceira cruz e confecção da raiz superior da anti-hélice.

Stahl's ear deformity was first described in the 19th century and it consists of a rare auricular deformity characterized by hypoplasia of the antihelix crus with enlargement of its base and a third crus of the antihelix connected to posterior portion of helix crus, which deforms the posterolateral wall of the external auditory canal. Reconstructive surgery is the definitive treatment, however, because of the diversity of clinical presentations, no standard technique exist for all cases. The method described in this report is another treatment option and entails the resection of the third crus and reconstruction of superior crus of the antihelix.

The Rolling Earlobe Flap for Dilated Ear Holes Following Ear Gauging: A Novel Approach to Aesthetically Preserving Earlobe Soft Tissue Volume

Patients are increasingly seeking repair of their earlobes following ear gauging. Research has shown that current repair techniques either excessively reduce the lobular volume or leave an obvious scar along the free edge of the earlobe. In our case series, we describe the use of a novel technique for repairing earlobes following ear gauging using a rolling earlobe flap that preserves the lobular volume and avoids leaving a scar on the free edge of the lobule. The procedure was performed on 3 patients (6 earlobes) who had defects from ear gauging that ranged from 3.0 to 6.5 cm. There were no postoperative complications of infection, wound dehiscence, flap necrosis, hypertrophic scars, or keloids, and all patients were highly satisfied with the postoperative results. This versatile technique allows for an aesthetically pleasing reconstruction of the lobule with the advantages of: the absence of a surgical scar on the free edge of the lobule, preserving the lobule volume, and presenting a highly customizable technique that allows lobules to be created with various shapes and volumes.

A Modified Closed Cartilage-Preserving Otoplasty Technique for Prominent Ear Correction

BACKGROUND: In the surgical correction of prominent ear, a technique known as percutaneous adjustable closed otoplasty (PACO), which does not involve skin incision, undermining, or cartilage manipulation, has been developed to resolve problems including hematoma, infection, contour deformities, prolonged use of a compressive dressing, and hospitalization. We modified this procedure to make it more practical and accessible and to achieve better results. In this article, we introduce our modifications and demonstrate the clinical applicability of the modified procedure to patients with hardened auricular cartilage. METHODS: Two adult patients with prominent upper ears underwent closed otoplasty in an outpatient setting. Based on the anatomical features of the patients, three lines for traction sutures were designed on the scapha and counter scapha. Tab incisions were made at all predetermined puncture sites. Three antihelix-forming sutures (4-0 nylon) were put in place via percutaneous punctures. The sutures were performed from the counter scapha to the postauricular sulcus subcutaneously, using an 18-mm empty curved needle. The sutures were scraped over the mastoid bone such that they were anchored to the mastoid periosteum. After determining an adequate auriculocephalic distance, the sutures were tied at the postauricular sulcus. A slight overcorrection was made to compensate for post-surgical relapse. RESULTS: We observed no complications such as hematoma, infection, contour deformities, epithelial inclusion cyst formation, suture extrusion, or dimples on the scapha. At a long-term follow-up examination, the patients had well-defined antihelical folds and were satisfied with the aesthetic results of the procedure. CONCLUSIONS: We propose our technique as a reliable treatment option for the correction of prominent ear.

O crescente número de traumas de orelha impõe soluções simples e eficazes. Objetivo: Ser capaz de reconstruir uma orelha parcialmente lesada por trauma, mesmo num pequeno hospital. Muitas técnicas podem ser usadas, porém a solução pode ser a utilização de um retalho cutâneo ou condrocutâneo. Métodos: Para reconstruir o 1/3 superior e/ou médio da orelha, um retalho cutâneo de mastoide associado ou não ao enxerto de cartilagem, ou um retalho condrocutâneo foi utilizado. Estes foram escolhidos levando-se em consideração o tamanho do defeito e a necessidade ou não do enxerto cartilaginoso. Resultados: Os pacientes puderam usar óculos e ficaram felizes com seus resultados. A maioria apresentou bom contorno de hélice e do arcabouço cartilaginoso. Alguns apresentaram cicatrizes hipertróficas das áreas enxertadas e dois solicitaram retoques tardios. Conclusão: O uso do retalho cutâneo de mastoide ou condrocutâneo local pode ser uma boa solução para as perdas parciais de orelha pós-trauma. A maioria dos pacientes apresentava expectativa muito alta sobre o que esperar da reconstrução da orelha. Isto determina um grande desafio técnico para o cirurgião e requer informações prévias sobre as reais possibilidades de resultados.

The growing number of ear trauma cases has brought about the need for simple and efficient solutions. AIM: To be able to rebuild an ear partially injured by trauma, even in a small hospital setting. Many techniques can be used; however, the solution can be the use of cutaneous or chondrocutaneous flaps. Methods: To reconstruct the ear upper or middle thirds we used a mastoid cutaneous flap with or without a cartilage graft or a chondrocutaneous flap - chosen considering the size of the defect and the need for a cartilage graft. Results: The patients were able to wear glasses and were pleased with the results. Most of the patients ended up having a good helix and cartilaginous contour. Some had hypertrophic scars on the grafted areas and two required a second procedure. Conclusion: Mastoid cutaneous flaps or local chondrocutaneous flaps can represent a good solution for partial ear loss after trauma. Most of the patients had very high expectations concerning the procedure. This poses a major technical challenge for the surgeon and requires prior discussion with the patients regarding the true possibilities of outcome.

Conclusão: A técnica é de fácil reprodutibilidade e uma boa opção para o tratamento da macrotia.

Introduction: Macrotia is a rare congenital ear deformity. Macrotic ears are out of proportion to the normal facial features. Few surgical techniques are described on the literature to treat this deformity. Objective: The experience of the Division of Plastic Surgery from University of São Paulo Faculty of Medicine on the correction of macrotia is presented. Methods: On a ten year period, eight patients with bilateral macrotic ears were treated. The technique used was that developed by Bauer. Results: Our results showed that an mean reduction of ear length in 1.37 cm and the width in 0.48 cm was achieved. There were no complications and the aesthetic results were satisfactory. The resection using natural ear creases has reduced both the length and width of the ear, preserving its proportions and positioning incisions and scars in a hidden location. Conclusion: This technique is easily reproducible and it is a good option for the treatment of macrotia.

Reparo do lóbulo da orelha partido: revisão da literatura e proposta de nova técnica / Split ear lobe repair: literature review and new technique proposal

A fenda do lóbulo da orelha normalmente resulta de trauma súbito ou uso contínuo de brincos pesados. Dentre as diversas técnicas cirúrgicas propostas para a sua correção, a escolha dependerá do tipo de fenda existente, parcial ou total, e deverá permitir a menor chance de recidiva. As correções da fenda total poderão ser feitas com ou sem preservação do orifício do brinco. A fixação do lóbulo durante a intervenção é fundamental, qualquer que seja a técnica utilizada, e pode ser feita com abaixador de língua estéril ou pinça de calázio. Para o procedimento cirúrgico, são utilizados pinça de Adson, tesoura íris e lâmina de bisturi 11 ou 15, sendo o fechamento da pele realizado com fio mononylon 5.0 ou 6.0. Na nova técnica descrita, obtém-se, além da vantagem da manutenção do pertuito, maior segurança ao apoio do brinco com menores chances de recidiva.

Split earlobe usually results from sudden trauma or continuous use of heavy earrings. Among the various surgical techniques proposed for split earlobe correction, the choice will depend on the existing split, partial or total, and should offer a lower chance of recurrence. The total split corrections may be made with or without preservation of the earring orifi ce. Lobe fi xation during intervention is essential, whatever the technique used, and can be done with tongue blade or sterile chalazion clamp. For the surgical procedure, we used Adson clamp, iris scissors, and scalpel blade 11 or 15. Skin suture was done with mononylon 5.0 or 6.0. In the new technique, besides the advantage of maintaining the orifi ce, there is greater security to support the earring with less chance of recurrence.
