Individual and ethnic aspects of preoperative planning for posttraumatic rhinoplasty
The aim of this study was to compare the aesthetic results of post traumatic rhinoplasty among Europeans with populations of healthy Caucasians described in earlier reports, and to collate correct parameters of nasal shape in healthy representatives of both sexes and various races for improvement in aesthetic results of surgery. 3-D scanning of the face was performed in 54 patients after posttraumatic septorhinoplasty. Analysis of 3D model was based on two indices of the nasal proportions and four angles of the region from 18 anthropological points. Parameters of the nasal shape in addition to gender were compared to average values of healthy Caucasian population, described before. Normal characteristics of the nose among individuals of three races from previous studies were also compared to one another. In females, mean height and width of the nose as well as length of both nostrils was smaller. Neither were there any significant differences in width of the nostrils and length of the nasal pyramid nor nasal prominence. Nasal proportions were similar in both sexes. Some of the nasal angles differed in addition to gender. Posttraumatic rhinoplasty resulted in correct shape of the nose similar to the healthy Caucasian population. The aesthetic nose differ among healthy individuals of the three races analysed. While preoperative planning is important, knowledge of the normal values of parameters characterising shape in both genders is equally important as the individual differences in relation to the whole face

Rinoplastia do nariz negróide por via intra-oral sem ressecções externas: avaliação da eficácia da técnica Negroid nose's rinoplasty through intra-oral approach without external excisions: evaluation of the efficiency of the technique
OBJETIVO: Avaliar a eficácia da técnica de redução da largura da base nasal do nariz negróide, modificando a inclinação dos eixos das narinas pela mobilização de tecidos internos, por abordagem intra-oral, evitando cicatrizes externas. MÉTODOS: Foram operadas 11 pacientes adulta do sexo feminino, com idade variando entre 19 a 45 anos, distribuindo-se em 2 da raça caucasóide e 9 da raça negróide, sendo desta 5 de cor parda e 4 de cor negra. O método de fotografia foi padronizado, e as imagens em papel foram digitalizadas. Por meio de software foram mensurados nas fotografias pré-operatórias e com 3 meses após a rinoplastia, 8 Ãndices relativos à base nasal baseados em pontos antropométricos. Os valores obtidos foram submetidos à análise estatÃstica descritiva e inferencial. RESULTADOS: Não houve diferença estatisticamente significante em 7 Ãndices relativos a redução da largura da base nasal e à inclinação dos eixos das narinas. Apenas houve alteração significante no aumento do Ângulo Nasolabial (p=0,001). CONCLUSÃO: A técnica de rinoplastia de nariz negróide por via intra-oral sem ressecções externas, apenas com mobilização dos tecidos internos, não é eficaz para a reduzir a largura da base nasal.<br>OBJECTIVE: To evaluate effectiveness of the technique of reduction of the width of the nasal base of negroid nose, modifying the inclination of the axes of the nostrils for the mobilization of internal tissues, through intra-oral approach, avoiding external scars. METHODS: Eleven adult female patients were operated with age varying between 19 to 45 years old, being distributed in 2 of the Caucasoid race and 9 of negroid race, being of this 5 brown color and 4 of black color. The picture method was standardized, and images in paper were digitized. Through software they were measured in the pre-operative pictures and with 3 months after the rhinoplasty. 8 relative indexes to the nasal base based on anthropometrics points. The obtained values were submitted to statistically descriptive analysis. RESULTS: No significant statistically differences were found in seven of these features, relative reduction of the width of the nasal base and the variation in the axis of the nostrils inclinations. Just one significant alteration found, an increased in the nasal labial angle (p=0,001). CONCLUSION: The technique of rhinoplasty of negroid nose through intra-oral approach without external resection, just with mobilization of the internal tissues is not effective to reduce the nasal base
