Alterações antropométricas da morfologia nasal em doentes propostos para rinosseptoplastia

Abstract

Background: Facial aesthetics surgery is an expanding area and rhinoplasty is one of the most common interventions in this field. Through anthropometry, it is possible to quantify the anthropometric parameters of the nose, being essential the recognition of deviations from the aesthetic standards. Objective: Measure anthropometric parameters of the nasal pyramid and face in patients proposed for rhinoseptoplasty, associate them with the aesthetic ideal and compare results between genders. Methods: This retrospective study involved 119 patients proposed for rhinoseptoplasty, 64 females and 55 males. Using photometry, the alar-intercanthal distance ratio, width-length ratio, nasofrontal angle, nasolabial angle, nasomental angle and projection of the nasal tip (Goode´s method) were obtained. A statistical analysis was performed to compare the measures obtained with the aesthetic ideals and between genders. Results: Compared to the ideal patterns, the sample presented an increased nasal tip projection, higher alar/intercanthal ratio, higher width/length ratio, increased nasofrontal and nasomental angles and a more acute nasolabial angle than the aesthetical pattern (p<0.001). Comparison between males and females revealed that the alar/intercanthal ratio and the width/length ratio were superior in males (p<0.001), while nasofrontal angle was superior in females (p<0.001). Nasomental angle, nasolabial angle and nasal tip projection had no differences between genders. Conclusion: The present study shows a statistically significant difference in all anthropometric measurements between patients proposed to rhinoseptoplasty and the aesthetic values described in the literature, as well as gender differences. Knowledge of nasal proportions of patients proposed to rhinoseptoplasty is crucial for surgeons in preoperative planning, comparative assessment and enhancement of surgical skills.
