结局指标
主要结局
Upper Lip Projection
时间窗: Baseline and 2 months
baseline upper lip position will recorded by measuring the Z-angle, which is the intersection of the Frankfort horizontal line and the profile line as described by Merrifield. From the straight portrait image, the ratio of the upper lip vermillion height to the lower lip vermillion height will be documented. Upper lip projection was assessed via measurement of the Z angle. On each subject's right lateral view photograph, a profile line was drawn tangential to the pogonion of the chin and to the most anterior point of the upper lip. A second line was drawn along the Frankfort horizontal plane. The resulting angle at which these two lines intersected corresponded to the Z angle. A decrease in the Z angle to a more acute value on post-treatment photographs would correspond to an increase in upper lip projection.
Nasal Tip Projection
时间窗: Baseline and 2 months
Baseline nasal projection measurements will be documented according to Goode's ratio. The Goode ratio was used as a measurement of tip projection and is defined as the ratio of the nasal height in relation to the nasal length. For each subject's right lateral view photograph, the nasal height was measured as the length of a line drawn from the alar-facial groove to the tip-defining point, and the nasal length was measured as the length of the line drawn from the nasion to the tip-defining point. The nasal height value was then divided by the nasal length value to determine the Goode ratio for a given photograph. The ratio of the line from the alar crease to the nasal tip to the nasion to the nasal tip should be . 55. If it is more than that the nose is overprojected, if it is under that ratio the nose is underprojected.
