ABSTRACT

The goal of aesthetic otoplasty is the correction of ear deformities by creating harmonious and symmetrical external ears, without visible scars. Otoplasty techniques based on the excision of postauricular skin are associated with high recurrence rates. Modern otoplasty is based on cartilage-cutting and cartilage-sparing techniques, alone or in combination, which lead to lower recurrence rates. Objective: We evaluated the efficacy of otoplasty combined with other techniques in the correction of ear deformities, based on a modified version of the "algorithm for otoplasty at the Craniofacial Center at Texas Children's Hospital". Methods: Forty patients, who underwent otoplasty for prominent ears in our institution between March and September of 2009, were prospectively assessed. The mastoid-helix distance was measured preoperatively (baseline) and at 1, 3, and 6 months postoperatively. Results: The most common deformities were scaphoconchal angle greater than 90° (51.3%, 41/80 ears) and conchal hypertrophy > 2.5 cm (46.3%, 37/80 ears). Recurrence occurred in 2 (5%) patients and partial stenosis of the ear canal in 1 (2.5%). Significant reductions in the mastoid-helix distance were observed at the three time points compared with baseline (P

O objetivo da otoplastia estética é a correção de deformidades da orelha, criando orelhas externas harmoniosas e simétricas. As técnicas de otoplastia, baseadas na excisão da pele pós-auricular, estão associados com a recorrência elevada. A otoplastia moderna é baseada nas técnicas de ressecção e/ou modelagem da cartilagem, que levam que menores taxas de recorrência. Objetivo: Foi avaliada a eficácia da otoplastia com técnica combinada na correção de deformidades da orelha, baseado numa versão modificada do "algoritmo para otoplastia", na Centro Craniofacial do Hospital Infantil do Texas". Método: Quarenta pacientes submetidos à otoplastia por orelhas proeminentes, entre março e setembro de 2009, foram avaliados prospectivamente. A distância mastoide-hélice foi medida no pré-operatório e após 1, 3 e 6 meses após a cirurgia. Resultados: As deformidades mais comuns foram ângulo escafo_concha I maior que 90° (51,3%, 41/80 orelhas) e hipertrofia de concha> 2,5cm (46,3%, 37/80 orelhas). Reduções significativas na distância mastoide_hélice foram observadas nos três períodos em comparação com os valores basais (P
