The Ideal Nasion in Chinese: A Preference Analysis of the General Population

Abstract

Augmentation rhinoplasty has gained popularity in China in the past decades and nasion profile is a key variable in aesthetic outcomes. The nasion is the deepest portion of the nasofrontal groove and its aesthetic preferences vary between different ethnic groups. At the time of this writing, there is limited research about ideal nasion measurements in the Chinese population. Therefore, we conducted an online survey of plastic surgeons and the public through social media. Participants were asked to rank nasion images according to their preferences. Images were created from a 3-dimensional scan of a Chinese Han female and modified to show various dimensions of nasion height, position, and forehead height. Nasion preferences were compared by age, sex, ethnicity, occupation, and whether had a history of plastic surgery. There were 777 respondents, including 461 (59.3%) women and 74 (9.5%) plastic surgeons. Nasion height of 8 and 10 mm ranked highest among all demographic groups. All respondents preferred nasion position to be level with the center of the pupil and forehead height of 4 mm above the nasion. Our study showed that the ideal Chinese nasion is in line with baseline ethnic characteristics. Therefore, plastic surgeons must be aware of these nasion preferences to guide preoperative discussions and achieve satisfactory outcomes.

Application of a Single T-Shaped Porous High-Density Polyethylene in Oriental Nasal Tip-Plasty

“…In our study, most nasal tips (93.8%) were improved with a PCC graft, with significant improvements in the nasal length ( P <0.0001) and nasal tip projection ( P =0.0005). There was also a significant change in the nasolabial angle similar to the aesthetic female nasolabial angle in a previous study 20 . The nasofrontal angle is a potentially important factor in the perception of facial profile attractiveness.…”

“…The nose is the central aesthetic feature of the face and the nasal length, nasal tip projection, and nasofrontal and nasolabial angle are the main parameters for anthropometric measurement in rhinoplasty. 20,21 Data from numerous anthropometric studies have shown that there are racial/ethnic differences in nasal measurements and even in the same race.

“…There was also a significant change in the nasolabial angle similar to the aesthetic female nasolabial angle in a previous study. 20 The nasofrontal angle is a potentially important factor in the perception of facial profile attractiveness. With the augmentation of nasion height in patients who seek dorsal augmentation rhinoplasty, the nasofrontal angle is simultaneously increased, 20,23 but there was no significant change in nasofrontal angle in our study, possibly because of many patients having undergone dorsal augmentation.…”
