Las variables fueron la respuesta al tratamiento y presencia o no de eventos adversos. Resultados: Predominó el sexo masculino, la localización en la concha de la oreja, subtipo clínico nódulo ulcerativo y el histológico sólido, con respuesta completa en la mayoría de los pacientes. Como eventos adversos más comunes se presentaron dolor en el sitio de inyección, fiebre, edema y eritema perilesional. Conclusiones: La respuesta al tratamiento fue favorable en la mayoría de los pacientes y los eventos adversos que se observaron fueron los descritos en la literatura sin cambio en la actitud farmacológica.

Background: Basal cell carcinoma of the auricular region is one of the most aggressive cancers and with the worst prognosis, is usually destructive and mutilating, therefore conservative treatment, such as the use of interferons, is important in routine medical practice. Objective: To evaluate the results of HeberFERON application in a series of patients with basal cell carcinoma in the auricular region. Methodology: An observational, descriptive and longitudinal study was conducted on a series of cases with clinical, dermoscopic and histopathologic diagnosis of basal cell carcinoma of the ear treated with HeberFERON at the Center Polyclinic in Sancti Spíritus city, during the period from February 20, 2017 through December 20, 2022. A total of 29 patients were included in the study. An evaluation was conducted at the start of treatment, during treatment, and 16 weeks after treatment; the patients were treated with 10.5 IU of HeberFERON by perilesional and intradermal injections three times a week until completing nine doses. The variables were the response to the treatment and the presence or absence of any adverse events. Results: The male sex predominated, location in the ear turbinate, clinical subtype ulcerative nodule and solid histologic subtype, with a complete response in the majority of patients. The most common adverse events were injection site pain, fever, edema, and perilesional erythema. Conclusions: The response to treatment was favorable in most patients, and the adverse events observed were those described in the literature, with no change in pharmacologic attitude.

Prurito ótico por carcinoma basocelular en conducto auditivo externo / Otic pruritus due to basal cell carcinoma of the external auditory canal

El carcinoma basocelular es el tumor cutáneo más frecuente en el área de cabeza y cuello; la exposición crónica al sol es el factor de riesgo más importante para este tumor. Suele manifestarse clínicamente con síntomas anodinos en estadios iniciales, lo que contribuye a que su diagnóstico sea difícil y tardío. Tiene un comportamiento localmente invasivo, especialmente a nivel del pabellón auricular. Este es el único caso descrito en el conducto auditivo externo no relacionado con la exposición al sol, con características clínicas y terapéuticas que lo hacen peculiar.

Basal cell carcinoma is the most frequent skin tumor in the head and neck area, and chronic sun exposure is the most important risk factor. It usually manifests clinically with anodyne symptoms in the early stages, which contributes to its difficult late diagnosis. It is locally invasive, especially at the level of the pinna. It is the only case described in the external auditory canal not related to sun exposure; it presents clinical and therapeutic characteristics that make it peculiar.

Application of free skin graft or auricle composite tissue in the correction of nasal flange retraction / 中华医学美学美容杂志

Objective:To investigate the clinical effect and application value of free skin or auricle composite tissue transplantation in the correction of nasal alar retraction.Methods:From August 2019 to January 2023, a total of 45 patients with nasal retraction (7 males and 38 females) were treated in Shanghai United Regal Medical Cosmetology Hospital. Age ranged from 18 to 46 years, with a mean of 26.6 years. All patients had retroalar margin retraction caused by insufficient alar lining to varying degrees, with a retraction distance between 2-5 mm, with an average retraction distance of 3.3 mm. 11 cases of nasal flange retraction were corrected by free transplantation of composite tissue of auricle directly. The remaining 34 patients were corrected by alar border cartilage graft and free skin graft.Results:During 2-18 months of follow-up, 41 patients had satisfactory results and no obvious complications. Partial necrosis of free skin was observed in 2 patients, ischemic necrosis of complex flap of auricle was observed in 1 patient, and necrosis of free skin was observed in 1 patient. In addition to the above complications, 3 patients reported that the correction of alar retraction did not achieve the expected effect, but indicated that they were satisfied with the surgical effect, which was considered to be caused by skin contracture and other factors. The overall satisfaction rate of all patients was 91.1%. After follow-up and statistics, 41 patients in this group were satisfied with the results, with an overall satisfaction rate of 91.12%.Conclusions:The application of free skin graft (or auricle composite tissue) to correct nasal alar retraction has the advantages of simple operation, wide indications and accurate efficacy, and is worthy of clinical promotion.

Efectividad de la reconstrucción de la oreja con cartílago costal en el tratamiento de microtias / Effectiveness of Auricle Reconstruction with Costal Cartilage for the Treatment of Microtias

Introducción: La reconstrucción de la oreja en la actualidad es un problema difícil de solucionar. Se han propuesto varias técnicas quirúrgicas y solo las que se basan en el uso de cartílago costal autólogo son las que se aceptan a nivel mundial. Objetivo: Evaluar la efectividad de la técnica de reconstrucción del pabellón auricular descrita por Burt Brent. Métodos: Se realizó un estudio cuantitativo con diseño descriptivo de corte transversal con 41 pacientes que presentaron microtia congénita o perdida adquirida de la oreja; a quienes se les realizó reconstrucción auricular con cartílago costal autólogo tratados en el Hospital "William Soler", el Centro de Investigaciones Médico-Quirúrgica y Clínica Central "Cira García" en el Servicio de Cirugía Plástica desde 1994 hasta 2019. Se describió y se documentó la técnica empleada descrita por Burt Brent. Se utilizó una escala de 10 puntos que se basó en la anatomía auricular normal para la valoración de los resultados. Resultados: Se encontraron 32 pacientes portadores de microtia congénitas (78,04 %) y 9 pérdidas traumáticas (21,95 %), predominó el sexo femenino (56,09 %). La incidencia fue mayor en el lado derecho (68,75 %) en pacientes con microtia congénita. En el 95 % de los casos se alcanzaron resultados favorables y satisfactorios. Conclusiones: La reconstrucción del pabellón auricular requiere el empleo de un fragmento de cartílago costal de suficiente tamaño, forma y proyección. La clave consiste en esculpir un marco cartilaginoso de la oreja y mantener estos detalles a través de la piel lo más semejante a la oreja normal. Para un resultado satisfactorio se requiere una alta especialización.

Introduction: Auricle reconstruction is, nowadays, a difficult problem to solve. Several surgical techniques have been proposed and only those based on the use of autologous costal cartilage are accepted worldwide. Objective: To evaluate the effectiveness of the auricle reconstruction technique described by Burt Brent. Methods: A quantitative study with a cross-sectional descriptive design was carried out with 41 patients who presented congenital microtia or acquired loss of the ear and who were performed auricle reconstruction with autologous costal cartilage in the plastic surgery service at Hospital "William Soler", Centro de Investigaciones Médico-Quirúrgicas and Clínica Central "Cira García", from 1994 to 2019. The used technique described by Burt Brent was, in turn, described and documented. A 10-point scale based on the normal atrial anatomy was used to assess the outcomes. Results: Thirty-two patients with congenital microtia (78.04 %) and nine traumatic losses (21.95 %) were found, with a predominance of the female sex (56.09 %). The incidence was higher on the right side (68.75 %) in patients with congenital microtia. Favorable and satisfactory outcomes were achieved in 95 % of cases. Conclusions: Auricle reconstruction requires the use of a costal cartilage piece of enough size, shape and projection. The key is to sculpt a cartilaginous framework of the ear and to maintain these details through the skin as close as possible to the normal ear. A high level of specialization is required for a satisfactory outcome.

The patients were followed up for more than 18 months continuously; the clinical efficacy, satisfaction with auricle morphology, and the occurrence of infection and recurrence were observed in the two groups.Results:The effective rate of surgical injection compression group (24 ears, 92.31%) was higher than that of surgical injection group (16 ears, 59.26%), and the difference was statistically significant (χ 2=5.121, P<0.05). The Vancouver scar scale (VSS) scores of the two groups at 6 months and 12 months after treatment were significantly lower than that before treatment, and the VSS score of the surgical injection compression group was lower than that of the surgical injection group, the difference was also statistically significant ( P<0.05). The satisfactory rate of the surgical injection compression group (22 ears, 84.62%) was higher than that of the surgical injection group (13 ears, 48.15%), and the difference was statistically significant (χ 2=4.048, P<0.05). The recurrence rate of the surgical injection compression group was significantly lower than that of the surgical injection group (χ 2=5.779, P<0.05); there was no significant difference in the infection rate between the two groups of patients after treatment (χ 2=0.001, P>0.05). Conclusions:Surgical resection of auricle keloids combined with local injection of corticosteroids and local shaping and compression can significantly improve the clinical efficacy, maintain the shape of the auricle, and the therapeutic effect is satisfactory.

Replantation of severed auricle distal to helix with microsurgical technique: Report of 5 cases / 中华显微外科杂志

Objective:To summarise the clinical experience in replantation of the severed auricle distal to helix with microsurgical technique.Methods:From December 2018 to October 2021, a total of 5 patients with severed auricle injury were treated in the Department of Hand and Foot Surgery of The Affiliated Hospital of Qingdao University. They were 4 males and 1 female with 23-62 years old. After complete debridement of the auricular pinna, the retrograde replantation method was used. For arteries: a dorsal vein of the foot was used to bridge the posterior auricular artery. For veins: 2 patients had the veins directly anastomosed, 2 had the arteriovenous bridging to the posterior ear vein with dorsal foot veins, and the veins in 1 case were not anastomosed. Among the patients, 2 developed venous occlusions after severed auricle, and were treated with bloodletting through small incision at the skin margin. Two patients who received the arteriovenous of the severed auriclse achieved good blood supply. All the patients underwent treatments including anti-freezing, anti-spasm and anti-infection after the emergency surgery. The follow-ups were conducted regularly by telephone and by display photos via WeChat after surgery.Results:All 5 severed auricles were successfully replanted and survived. Postoperative follow-up ranged from 3 months to 2 years, with an average of 10 months. In the 2 cases with venous crisis, the auricles had mild atrophy. All auricles had no obvious pigmentation, and had the sensation recovery back to normal in 1 year after surgery.Conclusion:The pre-judgment of blood vessel quality and high-quality microsurgery skills are the necessary pre-conditions for auricle replantation. For replantation of severed auricle, it is the key to prevent vascular crisis by having the injured blood vessels thoroughly removed.

Case for diagnosis. Pruritic erythematosquamous lesion in the auricle

Abstract Chromoblastomycosis is a subcutaneous mycosis with chronic evolution that mainly affects the lower limbs and, less frequently, the auricles. Clinically, it presents with papillary verrucous, nodular, and/or tumoral lesions, whether isolated or infiltrated, forming plaques and, sometimes, atrophic in some areas. Histopathologically, it is characterized by a dermal granulomatous inflammatory infiltrate, and the diagnosis can be confirmed by the presence of fumagoid bodies in anatomopathological or direct mycological exams. The treatment to be indicated will depend on the extent and location of the lesions, using systemic antifungals, surgical removal, cryotherapy, thermotherapy, and immunoadjuvants. The present study reports an atypical presentation of chromoblastomycosis on the auricle.

RESUMEN Fundamento: Los traumatismos del pabellón auricular, producidos por diversas causas, no se presentan con frecuencia, pero siempre son un reto para el cirujano encargado de la reconstrucción. Objetivo: describir los resultados de la cirugía reconstructiva del pabellón auricular. Métodos: estudio descriptivo, de serie de casos, realizado en el Hospital Dr. Gustavo Aldereguía Lima, de Cienfuegos, en el periodo 2015-2019. Se aplicó anestesia local en todos los casos (5), y las técnicas Tubo de Filatov, y la retro auricular, de Dieffenbach, las cuales fueron ilustradas a través de imágenes de los diferentes casos. Se analizó para cada paciente la edad, sexo y causa del traumatismo. Resultados: los pacientes presentados fueron relativamente jóvenes, y solo uno fue del sexo femenino. En 4 de ellos la pérdida parcial del pabellón auricular fue causada por traumatismos con armas blancas y mordidas humanas, respectivamente; en el paciente restante la ausencia de la estructura era congénita. En todos se combinaron ambas técnicas (Filatov y Dieffenbach) para la reconstrucción quirúrgica, con un resultado estético favorable. Conclusión: La serie presentada, aunque no es extensa, evidencia que es posible la rehabilitación de los defectos estructurales del pabellón auricular, ya sea parcial o total, mediante técnicas quirúrgicas sencillas que permiten alcanzar el resultado estético esperado.

ABSTRACT Background: Injuries to the pinna, caused by various causes, are not frequent, but they are always a challenge for the surgeon in charge of reconstruction. Objective: to describe the results of reconstructive surgery of the pinna. Methods: descriptive study, case series, carried out at the Dr. Gustavo Aldereguía Lima Hospital, Cienfuegos, in the period 2015-2019. Local anesthesia was applied in all the cases (5), and the Filatov tube techniques, and the retro auricular, of Dieffenbach, which were illustrated through images of the different cases. The age, sex and cause of the trauma were analyzed for each patient. Results: the patients presented were relatively young, and only one was female. In 4 of them, the partial loss of the auricle was caused by trauma with sharp weapons and human bites, respectively; in the remaining patient, the absence of the structure was congenital. Both techniques (Filatov and Dieffenbach) for surgical reconstruction were combined in all, with a favorable aesthetic result. Conclusion: The series presented, although not extensive, shows that it is possible to rehabilitate the structural defects of the auricle, either partially or totally, using simple surgical techniques that allow achieving the expected aesthetic result.

Comparação de técnicas cirúrgicas de correção de orelhas proeminentes: Mustardé versus Converse / Comparison of surgical techniques for prominent ear correction: Mustardé versus Converse

Introdução: As orelhas proeminentes, popularmente chamadas de "orelhas em abano", representam a deformidade congênita mais comum da orelha externa, atingindo cerca de 5% da população. Métodos: Estudo primário, prospectivo e de intervenção comparando os resultados de pacientes submetidos ao procedimento cirúrgico de correção de orelhas proeminentes por meio da técnica de Converse e de Mustardé, realizado no Serviço de Cirurgia Plástica do Hospital das Clínicas da Universidade Federal de Pernambuco (HC-UFPE). Resultados: Foram avaliados 20 pacientes, 10 por meio da técnica de Converse e 10 por meio de Mustardé, no período de junho de 2016 a dezembro de 2017. Ambos os grupos mostraram diminuição das distâncias mastoideas auriculares ao final do período de observação, variando de 6.67 a 14.6 mm, a depender da técnica cirúrgica e do ponto de avaliação, mas sem significância estatística. Quanto às distâncias mastoideas auriculares médias ao final do período de observação, observou-se diferença de no máximo 6.3mm entre os grupos avaliados, mas sem significância estatística. Em relação a simetria das orelhas dentro do mesmo grupo, o nível máximo de assimetria média nos grupos Mustardé e Converse foi de respectivamente 0.9mm e 0.5mm. A porcentagem da perda de correção das medidas obtidas cirurgicamente ao longo do período de observação em ambos os grupos variaram de 15-19%, no entanto, sem significância estatística. No que se refere as complicações, houve 1 (10%) caso de hematoma no grupo Mustardé. Conclusão: As técnicas de Converse e Mustardé demostraram não ter diferença estatística nos resultados.

Introduction: prominent ears, popularly called "flappy ears," represent the most common congenital deformity of the external ear, affecting approximately 5% of the population. Methods: Primary, prospective and intervention study comparing the results of patients undergoing the surgical procedure to correct prominent ears using the Converse and the Mustardé techniques, performed at the Plastic Surgery Service of the Hospital das Clínicas, Federal University of Pernambuco (HC) -UFPE). Results: Twenty patients were evaluated, 10 with the Converse technique, and 10 with the Mustardé technique, from June 2016 to December 2017. Both groups showed a decrease in auricular mastoid distances at the end of the observation period, ranging from 6.67 to 14.6 mm, depending on the surgical technique and the evaluation point, but without statistical significance. Regarding the average auricular mastoid distances at the end of the observation period, a difference of a maximum of 6.3 mm was observed between the evaluated groups, but without statistical significance. Regarding the symmetry of the ears within the same group, the maximum mean level of asymmetry in the Mustardé and Converse groups was 0.9 mm and 0.5 mm, respectively. However, the percentage of loss of correction of the measures obtained surgically during the observation period in both groups ranged between 15 and 19%, without statistical significance. Regarding complications, there was 1 (10%) case of hematoma in the Mustardé group. Conclusion: Converse and Mustardé techniques did not show statistical differences in the results.

ABSTRACT Townes-Brocks syndrome, described in 1972, is characterized by three major congenital anomalies: anorectal malformation, dysplastic ears and thumb anomalies. It is a rare genetic disorder with autosomal dominant inheritance and an estimated prevalence of 1/250.0000. Approximately 164 cases have been reported in the literature. In Colombia, only one case was previously reported in a scientific event. Our case report is the first published in an indexed journal. Our article aims to report the patient's phenotype and the state of art of Townes-Brocks syndrome.

A Comparative Study between Standard Weight‑Based Technique and Pinna Size-Based New Technique for Classic Laryngeal Mask Airway Size Selection in Pediatric Population

Introduction: The laryngeal mask airway (LMA) is a non-invasive supraglottic airway device designed to maintain the airway,which sits outside of and creates a seal around the larynx. In clinical practice, the most commonly used method for sizeestimation is the weight-based method. However, this may not be suitable due to lack of standardization in pediatric patients,emergencies, overweight, etc. Therefore, this study was undertaken to evaluate the efficacy of the new pinna size-basedmethod for the estimation of LMA size.Materials and Methods: A total of 100 pediatric patients, aged under 15 years, undergoing ambulatory surgeries, belonging toAmerican society of anesthesiologists (ASA) Grades I and II, were randomly divided into two groups: Weight-based and Pinnasize-based estimation. Parameters such as number of attempts and change of size required were monitored.Results: LMAs were inserted in both the groups in the first attempt. However, LMAs needed to be exchanged in 2% of casesin Group A and in 16% of cases in Group B.Conclusion: Pinna size-based estimation for the size of LMA is a convenient and feasible alternative to the traditional weightbased estimation.
