Brazilian Approach to Dorsum Preservation.

Brazil has always been a fertile place for plastic surgery techniques, especially cosmetic, and it was not different in rhinoplasty. In Brazil surgeons started using the dorsal preservation rhinoplasty in the 1970s. Techniques have changed, the problems and contraindications were challenged, and solutions proposed. As a result, indications were expanded to almost every kind of nose. Surface working executed with power tools, such as the piezoelectric device and the power drill, complemented the techniques and allowed for refinement in execution. Today the Brazilian preservation techniques are adopted and improved by many surgeons around the world.

Rinoplastia de preservación dorsal, una nueva filosofía: Experiencia en el Hospital Naval Almirante Nef / Dorsal preservation rhynoplasty, a new philosophy: Experience in the Almirante Nef Naval Hospital

Resumen Introducción: La rinoplastia de preservación dorsal es una técnica innovadora en rinoplastias de reducción primaria, logrando una adecuada ventilación nasal y resultados estéticos naturales. Objetivo: Describir los resultados estéticos y funcionales en pacientes sometidos a rinoplastias de preservación dorsal. Material y Método: Se realiza un estudio de intervención no aleatorio "antes-después", donde se evaluaron las variables estética y funcional previo a la cirugía y luego a los seis meses. La variable estética se evaluó mediante el cuestionario de Utrecht (CU), escala visual análoga de apariencia nasal (EVA) y set de fotos clínicas. La variable funcional mediante el cuestionario de NOSE (Nasal Obstruction Symptoms Evaluation). Resultados: Un total de 15 pacientes fueron sometidos a rinoplastia de preservación dorsal. No hubo complicaciones tanto intra como posoperatorias. Ningún paciente intervenido presentó irregularidades dorsales, asimetrías, ni deformidades en "V" invertidas. Se observó una mejoría estadísticamente significativa (p < 0,01) en los resultados del CU, EVA y NOSE. Conclusión: La rinoplastia de preservación dorsal ofrece como resultado una nariz funcional, con líneas dorsales posoperatorias naturales. Esta técnica no presenta estigmas quirúrgicos, por lo que no es necesario la utilización de injertos para reparación del dorso nasal. Es rápida y fácil de realizar por cualquier cirujano especialista en rinoplastias.

Abstract Introduction: Dorsal preservation rhinoplasty is an innovative technique in primary reduction rhinoplasty, achieving adequate nasal ventilation and natural aesthetic results. Aim: To describe the aesthetic and functional results in patients undergoing dorsal preservation rhinoplasties. Material and Method: A non-randomized "before-after" intervention study was carried out, where the aesthetic and functional variables were evaluated before surgery and then at six months. The aesthetic variable was evaluated using the Utrecht questionnaire (CU), the visual analog scale of nasal appearance (VAS), and a set of clinical photos. The functional variable using the Nasal Obstruction Symptoms Evaluation (NOSE) questionnaire. Results: A total of 15 patients underwent dorsal preservation rhinoplasty. There were no intraoperative and postoperative complications. No patient who underwent surgery presented dorsal irregularities, asymmetries, or inverted "V" deformities. A statistically significant improvement (p < 0.01) was observed in the UC, VAS, and NOSE results. Conclusion: Dorsal preservation rhinoplasty results in a functional nose, with natural postoperative dorsal lines. This technique does not present surgical stigmata, so it is not necessary to use grafts to repair the nasal dorsum. It is quick and easy to perform by any rhinoplasty surgeon.
