Objective assessment of surgical technique in rotation and nasal projection variation / Avaliação objetiva da técnica cirúrgica na variação da rotação e projeção nasal

ABSTRACT INTRODUCTION: In rhinoplasty, facial esthetic analysis is critical for proper surgical planning. Parameters such as rotation and nasal projection should be routinely evaluated. Few studies have objectively assessed changes in facial angles postoperatively. OBJECTIVE: To evaluate the effectiveness of medial intercrural sutures and of rotation of the nasal tip on the increase of rotation and nasal projection in Caucasian patients undergoing primary rhinoplasty. METHODS: A prospective study carried out between 2011 and 2013, with 27 patients treated with primary rhinoplasty with a basic technique by the same surgeon, with medial intercrural sutures and rotation of the nasal tip. Rotation and nasal projection were measured from photographs obtained preoperatively and after 12 months. RESULTS: All 27 patients completed the study. The mean age was 27.1 years. There was a mean increase of 8.4° in the rotation - a statistically significant value. There was no significant change in the projection. CONCLUSION: The medial intercrural and nasal tip rotation sutures are effective in increasing nasal rotation in Caucasian patients undergoing rhinoplasty.

RESUMO INTRODUÇÃO: Na rinoplastia, a análise estética facial é essencial para um planejamento cirúrgico adequado. Parâmetros como rotação e projeção nasal devem ser rotineiramente avaliados. Há poucos estudos que avaliem objetivamente as mudanças nos ângulos faciais no pós-operatório. OBJETIVO: Avaliar a eficácia das suturas intercrura mediais e de rotação da ponta nasal no aumento da rotação e projeção nasal em pacientes caucasianos submetidos à rinoplastia primária. MÉTODO: Estudo prospectivo realizado entre 2011 e 2013, com 27 pacientes submetidos à rinoplastia primária técnica básica, pelo mesmo cirurgião, com suturas intercrura mediais e de rotação da ponta nasal. Mediu-se a rotação e a projeção nasal a partir de fotografias no pré-operatório e 12 meses após. RESULTADOS: Todos os 27 pacientes completaram o estudo. A idade média foi de 27,1 anos. Houve aumento médio de 8,4° na rotação, com significância estatística. Não houve alteração significativa na projeção. CONCLUSÃO: As suturas intercrura mediais e de rotação da ponta nasal são eficazes no aumento da rotação nasal em pacientes caucasianos submetidos à rinoplastia.

Prospective Study of the Surgical Techniques Used in Primary Rhinoplasty on the Caucasian Nose and Comparison of the Preoperative and Postoperative Anthropometric Nose Measurements

Introduction The knowledge and study of surgical techniques and anthropometric measurements of the nose make possible a qualitative and quantitative analysis of surgical results. Objective Study the main technique used in rhinoplasty on Caucasian noses and compare preoperative and postoperative anthropometric measurements of the nose. Methods A prospective study with 170 patients was performed at a private hospital. Data were collected using the Electronic System Integrated of Protocols software (Sistema Integrado de Protocolos Eletrônicos, SINPE(c)). The surgical techniques used in the nasal dorsum and tip were evaluated. Preoperative and 12-month follow-up photos as well as the measurements compared with the ideal aesthetic standard of a Caucasian nose were analyzed objectively. Student t test and standard deviation test were applied. Results There was a predominance of endonasal access (94.4%). The most common dorsum technique was hump removal (33.33%), and the predominance of sutures (24.76%) was observed on the nasal tip, with the lateral intercrural the most frequent (32.39%). Comparison between preoperative and postoperative photos found statistically significant alterations on the anthropometric measurements of the noses. Conclusion The main surgical techniques on Caucasian noses were evaluated, and a great variety was found. The evaluation of anthropometric measurements of the nose proved the efficiency of the performed procedures. .

Electronic data collection for the analysis of surgical maneuvers on patients submitted to rhinoplasty

Introduction: In the health field, computerization has become increasingly necessary in professional practice, since it facilitates data recovery and assists in the development of research with greater scientific rigor. Objective: the present work aimed to develop, apply, and validate specific electronic protocols for patients referred for rhinoplasty. Methods: The prospective research had 3 stages: (1) preparation of theoretical data bases; (2) creation of a master protocol using Integrated System of Electronic Protocol (SINPE©); and (3) elaboration, application, and validation of a specific protocol for the nose and sinuses regarding rhinoplasty. Results: After the preparation of the master protocol, which dealt with the entire field of otorhinolaryngology, we idealized a specific protocol containing all matters related to the patient. In particular, the aesthetic and functional nasal complaints referred for surgical treatment (i.e., rhinoplasty) were organized into 6 main hierarchical categories: anamnesis, physical examination, complementary exams, diagnosis, treatment, and outcome. This protocol utilized these categories and their sub-items: finality; access; surgical maneuvers on the nasal dorsum, tip, and base; clinical evolution after 3, 6, and 12 months; revisional surgery; and quantitative and qualitative evaluations. Conclusion: The developed electronic-specific protocol is feasible and important for information registration from patients referred to rhinoplasty...

Estreitamento da base nasal no nariz caucasiano através da técnica de cerclagem / Nasal base narrowing of the caucasian nose through the cerclage technique

Introdução: Diversas técnicas podem ser realizadas para diminuir a base nasal (estreitamento), como ressecção de pele vestibular, ressecção de pele columelar, ressecção de pele em elipse do bordo narinário, descolamentos e avançamentos de pele (técnica V-Y de Berstein) e o uso de suturas na cerclagem da base nasal. Objetivo: Avaliar a técnica de cerclagem realizada na base nasal, através de rinosseptoplastia endonasal por técnica básica sem delivery, no nariz caucasiano, diminuindo a distância inter-alar e corrigindo o alar flare com consequente melhora da harmonia nasal no conjunto facial. Método: Realizado estudo retrospectivo através da análise das fotos e documentos clínicos de 43 pacientes, nos quais foi confeccionada a cerclagem da base nasal, através da ressecção de pele em elipse da região do vestíbulo e base nasal (técnica de Weir modificada), utilizando-se fio mononylon® incolor 4"0" com agulha reta cortante. O estudo foi realizado nos anos de 2008 e 2009 no Hospital Instituto Paranaense de Otorrinolaringologia - IPO em Curitiba-Paraná, Brasil. Os pacientes tiveram um follow up que variou de 7 a 12 meses. Resultados: Em 100% dos casos foi atingida uma melhora na harmonia nasal, através da diminuição da distância inter-alar. Conclusão: A cerclagem associada a ressecção mínima de pele vestibular e da base nasal é um método eficaz para o estreitamento da base nasal no nariz caucasiano, com resultados previsíveis e de fácil realização.

Introduction: Several techniques can be performed to reduce the nasal base (narrowing), as skin resection vestibular columellar skin resection, resection of skin in elliptical lip narinary, sloughing of skin and advancements (VY technique of Bernstein) and the use of cerclage sutures in the nasal base. Objective: To evaluate the technique of cerclage performed in the nasal base, through endonasal rhinoplasty without delivery of basic technique, in the Caucasian nose, reducing the distance inter-alar flare and correcting the wing with consequent improvement in nasal harmony in the whole face. Methods: A retrospective analysis by analysis of clinical documents and photos of 43 patients in whom cerclage was made of the nasal base by resecting skin ellipse in the region of the vestibule and the nasal base (modified technique of Weir) using colorless mononylon® 4 "0" with a straight cutting needle. The study was conducted in 2008 and 2009 at Hospital of Paraná Institute of Otolaryngology - IPO in Curitiba, Parana - Brazil. Patients had a follow up ranging 7-12 months. Results: In 100% of cases was achieved an improvement in nasal harmony, by decreasing the inter-alar distance. Conclusion: The encircling with minimal resection of vestibular skin and the nasal base is an effective method for the narrowing of the nasal base in the Caucasian nose, with predictable results and easy to perform.
