Relación entre la dimensión vertical oclusal y la longitud lineal del pabellón auricular / Relationship between occlusal vertical dimension and linear ear length

Resumen Introducción: La dimensión vertical oclusal en algunos casos se altera y para predecirla se suelen utilizar métodos, tanto subjetivos como objetivos y entre los que se encuentran los antropométricos. Objetivo: Evaluar la correlación entre la longitud lineal del pabellón auricular y la dimensión vertical en jóvenes dentados. Métodos: Se evaluaron 47 estudiantes a nivel de la longitud vertical del pabellón auricular (punto más superior al punto más inferior del lóbulo de la oreja), medición del canto exterior del agujero ocular al tragus y la dimensión vertical oclusal (situados en el punto subnasal y en el borde más prominente del mentón). Todas las mediciones se hicieron con un calibrador digital. Resultados: La dimensión vertical oclusal promedio fue de 65,68 ± 4,14 mm. La distancia promedio entre el canto externo del ojo al tragus derecho fue de 67 ± 3,52mm (correlación de r = 0,776; p < 0,01) mientras que en el lado izquierdo fue de 66,95 ± 3,98 mm (correlación de r = 0,733; p < 0,01). La distancia de la longitud del pabellón auricular en el lado derecho fue de 64,74 ± 4,47mm (correlación de r = 0,643; p < 0,01) mientras que en el lado izquierdo fue de 64,84 ± 4,46 mm (correlación de r = 0,657; p < 0,01). Conclusiones: Las medidas antropométricas de la longitud lineal del pabellón auricular derecho e izquierdo se correlacionó con la dimensión vertical oclusal así como la medición entre el canto externo del ojo al tragus también se correlación con la dimensión vertical oclusal(AU)

ABSTRACT Introduction: When occlusal vertical dimension becomes altered, as is sometimes the case, use should be made of subjective and objective methods, including those based on an anthropometric approach. Objective: Evaluate the correlation between linear ear length and vertical dimension in dentate young subjects. Methods: A total 47 students were evaluated for linear vertical ear length (from the highest to the lowest end of the earlobe), and measurements were taken from the outer edge of the ocular hole to the tragus and the vertical occlusal dimension (located at the subnasal point and the most prominent edge of the chin). All measurements were taken with a digital caliper. Results: Average vertical occlusal dimension was 65.68 ± 4.14 mm. Average distance from the outer edge of the eye to the right tragus was 67 ± 3.52 mm (r correlation = 0.776; p < 0.01), whereas on the left side it was 66.95 ± 3.98 mm (r correlation = 0.733; p < 0.01). Ear length distance was 64.74 ± 4.47 mm on the right side (r correlation = 0.643; p < 0.01) and 64.84 ± 4.46 mm on the left side (r correlation = 0.657; p < 0.01). Conclusions: Right and left linear ear length anthropometric measurements correlated with vertical occlusal dimension. The distance from the outer edge of the eye to the tragus also correlated with the vertical occlusal dimension(AU)

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.

Incision and drainage with daily irrigation for the treatment of auricular pseudocyst

Introduction: Pseudocyst of the pinna is a rare condition that occurs when fluid accumulates in the intercartilagenous space of the auricle. The main goal when treating this condition is to keep acceptable cosmetic results with no recurrence rate. Objective: To demonstrate the superior impact of incision and drainage of auricular pseudocysts with the insertion of a catheter drain and daily irrigation as the treatment of this condition. Methods: A total of 42 patients with auricular pseudocysts were enrolled in the present study in the period between May 2011 and May 2017. All of the patients were treated with incision and drainage with compression. The average follow-up time reached ~ 6 months in all of the cases. Results: All of the patients had satisfactory cosmetic results with no recurrence and no complications. Conclusion: Among the different methods of surgical treatment of pseudocyst of the pinna, incision and drainage with daily irrigation is a significantly efficientmethod both for the eradication of auricular pseudocysts and for good cosmetic results (AU)

Otoplastia Combinada / Combined Otoplasty

Introdução: Orelha em abano é a deformidade congênita mais comum de cabeça e pescoço, cuja transmissão se dá por herança autossômica dominante, sem predileção por gênero. A orelha proeminente ou "em abano" ocorre quando há um excesso ou hipertrofia da concha auricular, apagamento da antélice, um ângulo escafoconchal maior que 90º ou uma combinação destes, ocorrendo uni ou bilateralmente. O objetivo é apresentar uma abordagem conservadora para correção de orelha em abano, com a associação de técnicas. Métodos: Foi utilizada uma variação cirúrgica para realização de otoplastia com o auxílio de uma abordagem anterior para ressecção da concha auricular associada ao enfraquecimento da antélice com incisões parciais na cartilagem também por via anterior e a realização de pontos de Mustardé por via posterior para melhor definição da antélice, sem a fixação da concha à mastoide. Foram operados 200 pacientes com idade média de 17 anos, entre janeiro de 1987 e janeiro de 2015, sendo 60% do gênero feminino. Resultados: Dos 200 pacientes, apenas 24 necessitaram revisões cirúrgicas discretas. Conclusão: O procedimento cirúrgico é simples, facilmente reprodutível, proporcionando bons resultados, com alto grau de satisfação e baixo índice de complicações/morbidade.

Introduction: Protruding ear is the most common congenital deformity of the head and neck, with an autosomal dominant inheritance and no predilection for sex. Protruding ear or prominent ear occurs when there is concha excess or hypertrophy, erasure of the antihelix, a scapho-conchal angle greater than 90°, or a combination of these factors, occurring unior bilaterally. The objective is to present a conservative approach to correct protruding ear, with a combination of techniques. Methods: The otoplasty surgical technique involved an anterior approach for resection of the auricular concha, which was associated with weakening of the antihelix, and partial incisions of the cartilage were performed through anterior access and of Mustardé sutures, through posterior access for better definition of the antihelix without fixation of the concha to the mastoid. Two hundred patients with a mean age of 17 years underwent operations between January 1987 and January 2015, 60% of whom were female. Results: Of the 200 patients, only 24 patients needed discrete surgical revisions. Conclusion: The surgical procedure is simple, easily reproducible, provides good results, and is associated with a high degree of satisfaction and a low rate of complications/morbidities.

Multiple Epiphyseal Dysplasia: Uncommon Diagnosis in a Patient with Swelling over Pinna

Multiple Epiphyseal Disorder (MED) is a congenital birth disorder presenting with abnormalities of bone and cartilage and is of two types – dominant and recessive. Nearly 50% of individuals with recessive multiple epiphyseal dysplasia (rMED) are born with at least one abnormal feature, including clubfoot, cleft palate, clinodactyly, or ear swelling. A case report of 6-year-old male child with left ear swelling and deafness is presented to highlight the need for maintaining a high index of suspicion for this disorder. A missed or delayed diagnosis of this diagnosis may lead to an erroneous treatment plan

Carcinoma espinocelular del oído externo con extensión parotídea: a propósito de un caso / Squamous cell carcinoma of the external ear with parotid extension: case report

El pabellón auricular y el conducto auditivo externo constituyen una región anatómica que puede ser asiento de múltiples patologías, entre ellas procesos inflamatorios, infecciosos y neoplásicos, tanto benignos como malignos. Con respecto a los tumores, los diversos tipos suelen presentarse con síntomas y signos similares y en general es difícil inferir la variedad histológica del tumor a través del examen físico, por lo cual es necesario el estudio histopatológico para determinar el diagnóstico. La mayoría de los tumores del oído externo son carcinomas; entre ellos se destacan el carcinoma basocelular, el más frecuente, y el carcinoma espinocelular. Menos frecuentemente se encuentran otros tipos de tumores como los melanomas, adenocarcinomas, carcinomas de glándulas ceruminosas, carcinomas mucoepidermoides, sarcomas, procesos linfoproliferativos, etc. Suelen ocurrir en la edad media y avanzada (50-70 años) y con mayor periodicidad en el sexo masculino. En el presente trabajo se describe un caso clínico de carcinoma espinocelular del oído externo, tratado exitosamente mediante cirugía y radioterapia, así como también se describen las características clínicas de esta enfermedad, con especial atención al compromiso del oído externo por ella.

The pinna and the ear canal are an anatomical region that can be affected by many diseases, including inflammatory, infectious and benign and malignant neoplastic processes. With regard to tumors, various types usually present with similar symptoms and usually is very difficult to know the histological type through physical examination, so histopathological examination is necessary in order to determine the diagnosis. Most tumors are carcinomas; they can be basal cell carcinoma (more frequently), or squamous carcinoma. Less frequently are other types of tumors such as melanomas, adenocarcinomas, ceruminous glands carcinomas, mucoepidermoid carcinomas, sarcomas, lymphoproliferative disorders, etc. They usually present in middle and advanced age people (50-70 years) and are more frequently in men. In this article we present a case of squamous cell carcinoma of the external ear with extention to parotid gland, successfully treated with surgery and radiotherapy, as well as we describe the clinical characteristics of this disease, with special attention to the compromise of the external ear.

OBJETIVO: Avaliação dos resultados do fechamento de FLO's por meio de simples remoção de suas bordas e fechamento usando adesivo tissular. MÉTODOS: Estudo prospectivo no qual FLOs (36) foram tratadas por simples excisão de suas bordas epitelizadas e fechamento usando cianoacrilato como adesivo tissular. RESULTADOS: Foram tratadas FLOs causadas por brincos (91,7%) e por trauma (8,3%). Achatamento (14,8%), cicatriz inestética (13,9%), entalhe (11,1%), alongamento lobular (7,4%) e deiscência (5,6%) foram os problemas encontrados. Não houve casos de necrose ou queloides. CONCLUSÕES: O tratamento proposto mostrou-se seguro e com resultados cosméticos satisfatórios em 92,6% das pacientes.

INTRODUCTION: The use of ear ornaments is a multicultural practice. The lack of objective evaluations published in the national and international literature is surprising considering the high incidence of torn earlobe (TEL) worldwide. OBJECTIVE: Evaluation of the results of torn earlobe repair with simple marginal excision and closure using a tissue adhesive. METHODS: This was a prospective study in which TELs (36) were treated by simple excision of epithelialized edges and closure using cyanoacrylate as tissue adhesive. RESULTS: TELs caused by earrings (91.7%) and trauma (8.3%) were treated. The following issues were found: flatness (14.8%), unsightly scar (13.9%), notching (11.1%), stretched earlobe (7.4%), and dehiscence (5.6%). No cases of necrosis or keloid scars occurred. CONCLUSIONS: The proposed treatment proved safe and had satisfactory cosmetic results in 92.6% of patients.

Improvement of Adult BTE Hearing Aid Wearers' Front/Back Localization Performance Using Digital Pinna-Cue Preserving Technologies: An Evidence-Based Review

This systematic review evaluated the impact of using digital pinna-cue preserving technologies (PPT) on front/back sound localization for adult hearing aid users. Two peer-reviewed studies and two non-peer-reviewed studies were included. Lab-based and self-report outcomes were both assessed. The overall findings suggested that PPT was superior to omni-directional and full directional settings in a relatively quiet, well-controlled laboratory environment but not in the real world. However, observed individual differences in self-report measures suggested that PPT was potentially beneficial to certain hearing aid users. PPT candidacy was discussed and the importance of a pre-fitting interview/consultation was emphasized to assist clinicians in making a solid evidence-based and cost-effectiveness decision when prescribing hearing aids to adults with hearing impairment.

Reconstrução parcial de orelha pós-trauma: técnicas simples e eficazes / Partial reconstruction of the external ear after a trauma: simple and efficient techniques

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.

Unusual Presentation of Obesity-associated Dermatoses: Acanthosis Nigricans Involving Both Auricles

Acanthosis nigricans is prevalent in the general population and is the most common dermatological manifestation of obesity. It is typically observed in the flexural areas such as the neck, axillae, and groin. Herein we report an interesting case of extensive acanthosis nigricans involving the neck, axillae, groin, and, uncommonly, the sulci of both auricles in an otherwise healthy but obese 23-year-old patient.

Solitary tuberculous ulceration of Pinna: A rare presentation.

Tuberculosis of pinna is a rare presentation. We present a case of a 25 year-old woman who presented with a chronic, non-healing ulceration of pinna. On histopathological evaluation of the incisional biopsy from the lesion, she was found to have tuberculosis of pinna. She responded to 4-drug anti-tubercular treatment. To our knowledge, there has been no previous report of any similar case in the past.

Measurements of the ear pinna in Thais: The first report.

The contour of the normal ear pine was studied in 434 Thai people i.e. 686 ears. The subjects were 219 males and 215 females who had never had sever injury or ear surgery. There age group’s were studied years, 3-5 years and 18-20 years. Four measurements were done i.e. ear width and ear length using a sliding caliper and auriculo-cephalic angle and concho-scaphalic angle using a goneometer. The results of the study revealed that the average ear width in Thais of different age groups differed little : was not much different (2.9 + 0.3 cm. At aged 0 - 2 years, 3.3 + 0.4 cm. At age 18-20 years in males and 2.8 + 0.3 cm. To 3.0 + 0.2 cm. in females. However the average ear height increased significantly with age (4.8 + 0.6 cm. At 0-2 years, 6.2 + 0.2 cm. At 18 -20 years in males and 4.7 + 0.5 cm, 6.1 + 0.2 cm. In females). The average auriculo-cephalic angle increased rapid during the early period. The increment of this angle exceeded 85 per cent of adult size at the age of 3 - 5 years (22.3 + 3.8 degrees, at aged 0 - 2 years, 28.0 + 2.5 degrees at aged 3-5 years, 28.4 + 3.1 degrees at aged 18 - 20 years in males and 21.8 + 3.6 degrees, 27.1 + 2.6 degrees and 28.2 + 1.6 degrees respectively in females). In contrast, the concho-scaphalic angle increased gradually with age (79.0 + 4.9 degrees at age 0 -2 years, 82.1 + 4.1 degrees at aged 18.20 years in males, and 79.4 + 4.6 degrees, 82.2 + 4.2 degrees in females). Statistical analysis of all the measurements of the ear pinna showed that the ear width in man at age 18 -20 years is wider than in women (3.3 + 0.4 cm. Versus 3.0 + 0.2 cm.), the ear height was significantly different (between the sexes) from aged 9 -11 years onward (5.9 + 0.4 cm. Versus 5.6 + 0.4 cm.) but there were no significant differences in either the suriculo-cephalic or the concho-scaphalic angles between males and females. Thai ear measurements when comparined with ear measurements in Caucasians were significantly smaller. This may be attributed to the different body structure of the different races. However, the percentage ratio of ear width to ear height was similar i.e. 50.60 per cent in both populations. The auriculo-cephalic angles in Thais were in the same range as western people.
