ABSTRACT
Os princípios para uma rinoplastia bem-sucedida incluem consulta e planejamento pré-operatório e uma análise clínica abrangente que defina as metas da cirurgia. Mais recentemente, a digitalização e a impressão doméstica em 3 dimensões tornaram-se disponíveis. O objetivo deste estudo é descrever um método de digitalização em 3 dimensões e de impressão doméstica da anatomia real do paciente para ser usada como ajuda intraoperatória. Nós apresentamos uma forma de uso desta tecnologia no transoperatório, auxiliando o cirurgião a comparar os resultados obtidos após suas manobras, verificar a sua adesão ao plano cirúrgico previamente estabelecido e melhorar a sua tomada de decisão durante a cirurgia. Em conclusão, a aplicação da impressão doméstica em 3 dimensões demonstra um efeito positivo sobre o tratamento de alterações estéticas do nariz.
The principles for a successful rhinoplasty include preoperative consultation and planning, as well as a comprehensive clinical analysis and defining rhinoplasty goals. Three-dimensional domestic scanning and printing have recently become available. We sought to objectively describe this method as an intraoperative aid in patients' anatomy. This method can be used trans-operatively to help surgeons compare the results of his or her technique, check adherence to the surgical plan, and improve his or her surgical decision-making. We found that the application of 3-dimensional printing had a positive effect on the treatment of patients with aesthetic nose disorders.

Introduction: Refinement of the nose tip can be accomplished by a variety of techniques, but currently, the use of sutures in the nasal tip with conservative resection of the alar cartilage is the most frequently recommended approach. Objective: To classify the nasal tip and to demonstrate the interdomal suture applied to nasal tip refinement in the Caucasian nose, as well as to provide a simple and practical presentation of the surgical steps. Method: Development of surgical algorithm for nasal tip surgery: 1. Interdomal suture (double binding suture), 2. Interdomal suture with alar cartilage weakening (cross-hatching), 3. Interdomal suture with cephalic removal of the alar cartilage (McIndoe technique) based on the nasal tip type classification. This classification assesses the interdomal distance (angle of domal divergence and intercrural distance), domal arch width, cartilage consistency, and skin type. Interdomal suture is performed through endonasal rhinoplasty by basic technique without delivery (Converse-Diamond technique) under local anesthesia Conclusion: This classification is simple and facilitates the approach of surgical treatment of the nasal tip through interdomal suture, systematizing and standardizing surgical maneuvers for better refinement of the Caucasian nose...

Esta revisión aborda específicamente el uso de materiales aloplásticos en rinoplastía. Es importante destacar que los injertos autólogos siguen siendo los materiales preferidos en rinoplastía, debido a su alta biocompatibilidad y bajo riesgo de infección y extrusión. Sin embargo, las dificultades relacionadas al sitio donante, disponibilidad del injerto y reabsorción de éste han motivado el desarrollo y uso de implantes aloplásticos. Después de leer este artículo, el lector debe ser capaz de identificar los usos apropiados de implantes aloplásticos en reconstrucción y reconocer las ventajas y desventajas de cada uno de estos biomateriales.
This review specifically addresses the use ofalloplasts materials in rhinoplasty. It is important to stress that autologous grafts remain the preferred material for use in rhinoplasty, owing to their high biocompatibility and low risk of infection and extrusion. However, concerns of donor-site morbidity, gran availability, and gran resorption have motivated the development and use ofalloplasts implants. After reading this article, the reader should be able to identify the appropriate uses of various implants in reconstruction and recognize the advantages and disadvantages of each of these biomaterials.

Presentamos este trabajo con el propósito de difundir y demostrar la eficacia de los injertos de cartílago en el perffeccionamiento de la rinoplastía. El trabajo se realizó en el Servicio de Cirugía Plástica del Hospital Víctor Lazarte Echegaray IPSS de Trujillo, Perú, entre abril de 1994 y agosto de 1998. Se operó a 31 pacientes usando injertos cartilaginosos autólogos de diverso tfamaño y forma para p;erfeccionar el rfesultado de la rinoplastía. Los paciedntes operados fueron 17 varones y 14 mujeres, cuya edad p;romedio fue 29.3 años. La indicación de la rinoplastía fue en nueve pacientes con fines estéticos (proyección secundaria, fracturas nasales, desviaciones de la pirámide nasal yh secuela de labio fisurado). Los 31 pacientes presentaron resultados satisfactgorios, ningún paciente experimentó rechazo del injerto, no se observaron complicaciones de importancia. Un paciente necesitó de revisión en área diferente a la del injerto. Se concluye que el uso de injertos cartilaginosos es seguro y necesario en las operaciones de rinoplastía para proyectar la punta y tratar depresiones del dorso de la nariz

A 25 pacientes de uno y otro sexo y en buenas condiciones generales, se les hizo rinoseptoplastía bajo anestesia general balanceada e hipotensión controlada inducida con 2.4 mcg/kg de peso/minuto de nitroprusiato de sodio, previa administración de 1 mg/kg de peso de propanolol. La técnica permite un flujo sanguíneo periférico adecuado y no se hicieron aparentes signos de complicaciones neurológicas, cardiocirculatorias o metabólicas. Se describen los diferentes procedimientos anestésicos para el manejo de este grupo de pacientes y las consecuencias que conlleva la infiltración de catecolaminas exógenas y la liberación de sustancias vasoactivas endógenas
