ABSTRACT
Abstract Objectives Prominent ear abnormalities affect 5% of the population. A prospective, double-blind study of patients who underwent otoplasty procedures to correct these abnormalities was conducted to compare two surgical techniques. They diverge by the preservation or not of conchal cartilage. Methods The two techniques were compared by measuring the cephalo-auricular and scapho-conchal angles. Measurements were performed in pre and 6-months post-operative periods using alginate molding. Twenty patients were randomly assigned to two groups (with and without cartilage preservation) with 10 participants each. Student's t-test, Covariance Analysis Model (ANCOVA), and non-parametric Mann-Whitney were used in the statistical analyses. Results A significant reduction in the average of the cephalo-auricular and scapho-conchal angles was observed in both surgical procedures (p < 0.001). However, no significant difference was found between them (p = 0.887). Conclusion The two techniques analyzed in this study fulfilled their objectives. Therefore, further comparative studies are needed to confirm the superiority of one over the other. Level I Evidence obtained from at least one properly designed randomized controlled trial.
ABSTRACT
Abstract Introduction The ear deformity Tanzer type V, also known as prominent ears, is the most common genetic defect of the pinna. The surgery designed for its correction is known as otoplasty. This esthetic surgery can be performed using different techniques, which requires great skill of its operator. Objective The purpose of this work is the development of a new tool for otoplasty techniques training, aimed on the possibility to minimize errors during the otoplasty. Methods Synthetic molds of the external ear from patients with Tanzer type V deformity were made, using silicone material and rayon. Results The main procedures of otoplasty could be performed in the molds made of silicone and rayon with a good esthetic result. Conclusion The elaborated molds had identical size and shape of a human ear and could be positioned in the same shape of the patient ears. Thus, the synthetic molds were presented as promising simulation tools for the training and surgical enhancement of otoplasty, especially for doctors beginners.
Resumo Introdução A deformidade da orelha tipo V de Tanzer, também conhecida como orelhas proeminentes, é o defeito genético mais comum da aurícula. A cirurgia criada para sua correção é conhecida como otoplastia. Essa cirurgia estética pode ser feita com diferentes técnicas, o que requer grande habilidade de seu operador. Objetivo O objetivo desse trabalho é o desenvolvimento de uma nova ferramenta para o treinamento de técnicas de otoplastia, com o objetivo de minimizar erros durante a otoplastia. Método Foram feitos moldes sintéticos da orelha externa de pacientes com deformidade tipo V de Tanzer com material de silicone e rayon. Resultados Os principais procedimentos de otoplastia foram feitos nos moldes de silicone e rayon com um bom resultado estético. Conclusão Os moldes elaborados tinham tamanho e forma idênticos aos de uma orelha humana e puderam ser posicionados no mesmo formato das orelhas dos pacientes. Assim, os moldes sintéticos foram apresentados como ferramentas de simulação promissoras para o treinamento e aperfeiçoamento cirúrgico da otoplastia, especialmente para médicos iniciantes.

Objective@#To investigate the feasibility and efficiency of refined Converse otoplasty with Ω shape for correcting prominent ears.@*Methods@#Refined Converse otoplasty with Ω shape was performed in 8 cases(3 cases of bilateral deformities)of prominent ears during January 2014 to September 2016. The postauricular fascial-perichondrial complex tissues were elevated through postauricular incision based on Converse otoplasty. The new antihelix was reformed by parallel mattress sutures though postauricular parallel cartilaginous incisions. The Ω shape appeared on the transverse section of the auricular cartilage after fascial-perichondrial sutures.@*Results@#Postoperative 6 month to one year follow-up presented satisfactory results in all 8 cases. The appropriate location and contour of the recreated antihelix was achieved. The included angle between fossae helicis and concha was decreased. The auricles were symmetric in both unilateral and bilateral patients of prominent ears. The scars were inconspicuous. Hematoma, infection, suture extrusion and secondary deformities were not seen in our series.@*Conclusions@#Natural and clear contour of the recreated antihelix was achieved by refined Converse otoplasty with Ω shape. Reoccurrence was not seen and complications were rare.
ABSTRACT
External ear anomaly was not uncommon disease. The spectrum of anomaly is wide, from mild anomalies including prominent ears, cryptotia to absence of external ear. In western countries, prominent ears were common and surgical correction was usually performed in their childhood period. However in Asian countries, including Korea, prominent ears were not considered correcting condition. Many techniques and skills were introduced to perform otoplasty since 19th century. For improving surgical result of otoplasty, operator should choose suitable surgical techniques considering patient's condition in these techniques and can read demands of patients.
