Measurement of Hunan Han young female nasal shape and its application for short nose rhinoplasty / 中华整形外科杂志

ABSTRACT

Objective@#To explore the measurement of Hunan Han young female nasal shape and its application for short nose rhinoplasty.@*Methods@#From June to December 2015, 162 Han young females in Hunan Xiangtan were chosen. Their photographs were used by the photogrammetry for measuremnet of nasal length, nasal height, nasal breadth, nasal depth, nasolabial angle, nasofrontal angel, nasorostral angel, columellar-facial angle, nose width-nose height index, nasal depth-nose width index, nasion to tip-defining point. The measurementresult were collected to create nasal shape database. During the period of January to June 2016, the database was applied to thirty-nine cases with short nose, to serve as guidelines for preoperative design and postoperative evaluation. Independent sample t-test was used to evaluate theresult of the operations by comparing the postoperative data with the nasal shape database of Hunan female nose assessment system.@*Results@#The measurementresult of Hunan Han young female nasal shape were as follow nasal length (4.4±0.2) cm, nasal height(4.8±0.2) cm, nasal width (3.3±0.2) cm, nasal depth (1.8±0.2) cm, nasolabial angle (88.6±7.0)°, nasofrontal angle (136.0±5.5)°, columellar-facial angle (33.3±3.0)°, nasal tip angle (82.4±5.4)°, nose width-nose height index 70.4±4.8, nasal depth-nose width index 55.1±5.7, nasion to tip-defining point (47.4±11.4)%.The short noses deformity was corrected greatly. The measurement data of nasolabial angle, nasofrontal angel, nasorostral angel, columellar-facial angle, nose width-nose height index, nasal depth-nose width index and nasion to tip-defining point had no statistical significance between postoperative patient and Hunan female, but nasal length, nasal height, nasal width and nasal depth difference have statistical significance.@*Conclusions@#The Hunan Han young female nasal shape database could provide quantitative reference for preoperative design, performance and post-operative aesthetics evaluation.
