Unlocking nasal angle anthropometry and nasolabial angle preferences: a key to achieve the perfect rhinoplasty

Abstract

Objectives: Determining the ideal nasolabial angle is very important for setting aesthetic goals in rhinoplasty. By knowing the demographic data of the three main nasal angles, which are the key to facial balance, indications, planning and peroperative evaluations of surgery can be better applied. The aim of this study was not only to measure nasal angles but also to find out the nasolabial angle preferences of the Anatolian population. Methods: 142 participants had their nasal angles (nasolabial, nasofrontal, nasofacial angles) measured both digitally and manually and a questionnaire was administered. Each participant was asked about their ideal nasolabial angle preferences and their propensity for rhinoplasty. The results were then compared between each other, age and gender. Results: According to digital measurements, the mean nasolabial angle was 99.51±9.51° in men and 100.49±9.37° in women. The mean nasofacial angle was 32.35±3.44° mm in men and 32.54±3.17° in women. The mean nasofrontal angle was 138.49± 9.29° in men and 141.64±8.10° in women. Manual measurements were similar. The mean ideal nasolabial angle in women (91.32±6.11°) was lower than the mean ideal nasolabial angle in men (94.78±4.47°). It was observed that the aesthetic perception of the participants was similar whether they had rhinoplasty or not. Participants aged less than 24 years were more likely to prefer higher nasolabial angles. Conclusion: The nasal angles and preferred nasolabial angle results presented in this study may be useful in planning and evaluating rhinoplasty operations.
