Reconstrucción de defecto de órbita con colgajo prelaminado de fascia temporal superficial / Orbit defect reconstruction with pre-laminated temporal superficial fascia flap

El colgajo de fascia temporal superficial es muy versátil para la reconstrucción de defectos tisulares localizados en los tercios superior y medio de la cara, en la región orbito-palpebral, en la cavidad oral, en la base del cráneo y a nivel mandibular. En nuestra experiencia, constituye una opción segura para reconstrucciones complejas de cavidades. En el presente artículo los autores exponen el caso de una paciente en quien se reconstruyó un defecto de órbita con un colgajo de fascia temporal superficial prelaminado

The superficial temporal fascia flap is versatile for the reconstruction of tissue defects located in the upper and middle thirds of the face, in the orbital-palpebral region, in the oral cavity, at the base of the skull and at the mandibular level. In our experience, it is a safe option for complex cavity reconstructions. In this article the authors present the case of a patient in whom an orbit defect was reconstructed with a pre-laminated superficial temporal fascia flap

Comparison between clinical and audiological results of tympanoplasty with modified sandwich technique and underlay technique / Comparação entre os resultados clínicos e audiológicos de timpanoplastia com a técnica "sanduíche" modificada e a técnica underlay

Abstract Introduction: Surgical repair of the tympanic membrane, termed a type one tympanoplasty is a tried and tested treatment modality. Overlay or underlay technique of tympanoplasty is common. Sandwich tympanoplasty is the combined overlay and underlay grafting of tympanic membrane. Objective: To describe and evaluate the modified sandwich graft (mediolateral graft) tympanoplasty using temporalis fascia and areolar fascia. To compare the clinical and audiological outcome of modified sandwich tympanoplasty with underlay tympanoplasty. Methods: A total of 88 patients of chronic otitis media were studied. 48 patients (Group A) underwent type one tympanoplasty with modified sandwich graft. Temporalis fascia was underlaid and the areolar fascia was overlaid. 48 patients (Group B) underwent type one tympanoplasty with underlay technique. We assessed the healing and hearing results. Results: Successful graft take up was accomplished in 47 patients (97.9%) in Group A and in 40 patients (83.3%) Group B. The average Air-Bone gap closure achieved in Group A was 24.4 ± 1.7 dB while in Group B; it was 22.5 ± 3.5 dB. Statistically significant difference was found in graft healing rate. Difference in hearing improvement was not statistically significant. Conclusion: Double layered graft with drum-malleus as a 'meat' of sandwich maintains a perfect balance between sufficient stability and adequate acoustic sensitivity.

Resumo Introdução: O reparo cirúrgico da membrana timpânica, denominado timpanoplastia tipo 1, é uma modalidade de tratamento já bem estabelecida. As técnicas overlay ou underlay de timpanoplastia são comuns. A timpanoplastia "sanduíche" é a técnica de enxerto de membrana timpânica overlay e underlay combinadas. Objetivo: Descrever e avaliar a timpanoplastia com a técnica "sanduíche" modificada (timpanoplastia mediolateral) utilizando fáscia temporal e fáscia aureolar. Comparar o desfecho clínico e audiológico da timpanoplastia com a técnica "sanduíche" modificada com o da timpanoplastia com a técnica underlay. Método: Foram estudados 88 pacientes com otite média crônica, 48 (Grupo A) foram submetidos à timpanoplastia tipo 1 com enxerto "sanduíche" modificado. A fáscia temporal foi utilizada na técnica underlay e a fáscia areolar na técnica overlay. 48 pacientes (Grupo B) foram submetidos à timpanoplastia tipo 1 com a técnica underlay. Foram avaliados os resultados da cicatrização e da audição. Resultados: O sucesso do enxerto ocorreu em 47 pacientes (97,9%) no Grupo A e em 40 (83,3%) do Grupo B. O fechamento médio do gap aéreo-ósseo no Grupo A foi de 24,4 ± 1,7 dB, enquanto no Grupo B foi de 22,5 ± 3,5 dB. Houve diferença estatisticamente significativa na taxa de cicatrização do enxerto. A diferença na melhora auditiva não foi estatisticamente significante. Conclusão: O enxerto de camada dupla e o tímpano-martelo posicionados como o "recheio" do sanduíche mantém um equilíbrio perfeito entre a estabilidade necessária e adequada sensibilidade acústica.

Manejo del sulcus vocalis con injerto de fascia temporal / Sulcus vocalis management with fascia temporal graft

El sulcus vocalis es una lesión en la cual el epitelio del pliegue vocal tiende a invaginarse y adherirse al ligamento y/o músculo resultando en disfonía. Existen múltiples tratamientos descritos ninguno con resultados ideales. Este es un estudio descriptivo-prospectivo en el Hospital Militar Central en pacientes operados por sulcus vocalis tipos II y III e implantados con fascia autóloga entre junio de 2006 y diciembre de 2008. De 17 pacientes operados cumplieron los criterios de inclusión 11. Edad promedio 32 años. 9 presentaron mejoría del análisis acústico de la voz con una tendencia a la mejoría en todas las variables, particularmente en el Shimmer y la frecuencia fundamental. En la estroboscopia, 10 pacientes presentaron recuperación de la onda mucosa y en 5 del cierre glótico. Ningún paciente presentó reacciones adversas al procedimiento. Del presente estudio se puede considerar que el manejo del sulcus vocalis con injerto autólogo de fascia temporal es un procedimiento seguro que en la mayoría de los casos representa una mejoría subjetiva y objetiva de la calidad de voz. Es necesario aumentar el tamaño de la muestra para obtener resultados de mayor poder estadístico y definir los criterios de éxito.

Sulcus vocalis is an injury in which the epithelium of the vocal fold tends to invaginate and attach to the ligament and / or muscle resulting in dysphonia. There are multiple treatments as described but none has ideal results. This is a descriptive – prospective study carried out at the Hospital Militar Central in patients that had been operated on due to sulcus vocalis of the type II and III and who have been given implants with autologous fascia between June, 2006 and December, 2008. Out of 17 patients that were operated on, 11 complied with the inclusion criteria. The average age was 32 years old. 9 of them exhibited an improvement on the acoustic analysis of the voice with a tendency to improvement in all variables, especially in Shimmer and the basic frequency. 10 patients exhibited a recovery of the mucous wave in the stroboscope analysis and 5 in the glottal closure. Not one patient showed adverse reactions to the procedure. It can be considered from this study that managing sulcus vocalis with a temporalis fascia autologous graft is a safe procedure that represents a subjective and an objective improvement of the quality of the voice. It is necessary to increase the size of the simple in order to obtain results with a greater statistical power and be able to define the criteria for success.
