ABSTRACT
Objective:To observe and evaluate reductional M-shaped plasty method in patients with thick lips and dissatisfied lip appearance.Methods:From 2013 to 2019, 415 Chinese cases of thick upperlip without clear vermilion curve and tubercle were included. A reduction method for upper lip M-shaped plasty was performed. Objective data of lip morphology before and after operation were measured, and subjective satisfaction survey and long-term follow-up were conducted.Results:According to the statistics of 415 patients, the time of detumescence was 3-21 (11.8±2.6) days; the time of incision scar softening was 1-24 (2.6±0.8) months; the time of expression recovery was 1-24 (3.1±1.4) months; the time of numbness disappearance was 1-2 years. Three months after the operation, there was no significant change in the height of the central part of the upper red lip compared with that before the operation, the height of the red lip at the peak of the lip was significantly reduced, the height of the red lip was (13.3±2.2) mm before the operation, and (11.4±1.7) mm after the operation; the relative height of the dome point was significantly increased, the height was (0.4±1.0) mm before the operation, and the height was (2.1±0.5) mm after the operation. After more than 6 months of follow-up, patients' satisfaction rate of one operation was 72.0%, the satisfactory rate of upper lip shape was 75.4%, the long-term complications included obvious scars or discomfort (3.6%), local numbness (1.7%), and unnatural expression (0.7%).Conclusions:The reduction method for upper lip M-shaped plasty displays a significant effect in improving the shape of upper vermilion with thick and normal lips. The complications are slight and repairable. This lip cosmetology and rejuvenation procedure is recommended for further clinical application.
ABSTRACT
Objective:To prove the effect of double V-Y procedure for paramedian tubercles plasty in patients with thin lower lips and dissatisfied appearance of lower lips.Methods:From 2013 to 2019, 127 Chinese cases of thin and dissatisfied appearance of lower lips were included. A double V-Y procedure for paramedian tubercles plasty was performed. Objective data of lip morphology before and after operation were measured, and subjective satisfaction survey and long-term follow-up were conducted.Results:The midline lower red lip height, the height of paramedian tubercles of lower-lip and the protrusion of lower-lip were significantly higher than that before the operation. The time of apocatastasis, scar softening of incision, natural expression recovery and local numbness relief were evaluated by following up at 7 d, and 3-24 months after operation, and it showed 73.2% of subjective satisfaction. The time of detumescence was 6-32 (15.2±3.5) days; the time of incision scar softening was 2-10 (5.1±2.3) months; the time of expression recovery was 1-7 (3.1±0.9) months; the time of numbness disappearance was 5 d-2 years (158.2±82.6) days.Conclusions:The double V-Y advancement of vermilion mucosa flap procedure for paramedian tubercles plasty displays a significant effect in improving volume and shape of lower lips. It is recommended for further clinical application.
ABSTRACT
Objective@#To summarize and update the terminology of the lip and perioral morphological aesthetic subunits and aesthetic landmarks in the domestic medical aesthetics field.@*Methods@#36 English literatures, 13 Chinese literatures, 3 foreign academic compositions, 2 domestic academic compositions, 1 domestic medical aesthetics textbook, and 14 websites of the medical aesthetic field have been included. We summarized the commonly seen terminology of the lip and perioral morphological aesthetic subunits and aesthetic landmarks. Moreover, for the aesthetic subunits and aesthetic landmarks which are commonly used in clinical practice but have not yet been named in Chinese term are named following the current Chinese terminology rule. We summarized not only the terminology of lips but also the anatomical acknowledge of the commonly used aesthetic subunits.@*Results@#There are 17 standard nomenclatures for aesthetic subunits, 8 standard nomenclatures with abbreviations for aesthetic surface landmarks, 20 standard terms for aesthetic measurement and distance. Moreover, we named 5 aesthetic subunits and 6 aesthetic surface landmarks for which there are no standard Chinese medical terms.@*Conclusions@#The standard terminology for the aesthetic subunits and landmarks is the foundation for the lip and perioral measurement and evaluation. Besides, it also provides a reference basis for the development of lip cosmetic and perioral rejuvenation treatment programs.
ABSTRACT
Objective To explore the feasibility of our method on assessing the three-dimensional facial morphological features based on three-dimensional surface imaging techniques.Methods According to the admission criteria,three-dimensional facial images of 34 attractive young Chinese women and 172 healthy reference young women were selected from the three-dimensional facial images database of our department.For those images,anthropometric facial measurements including facial height,width,the degree of convexity and concavity were computed using three-dimensional surface imaging techniques combined with three-dimensional coordinate system.The variance between attractive group and reference group was analyzed and the facial morphological features of each group were preliminarily summarized.Results Both groups met the criteria of mesoprosopy,not the "vertical facial trisection and rule of fifths".The attractive group had a relatively narrow anterior facial frame,a more rounded and full upper face compared with the reference group.They also had smaller intercan thai width compared with the reference group.Moreover,the attractive group showed more prominent nose,more full and prominent medial cheek.In addition,the attractive group shared less protruded upper lips and less retruded chin compared with the reference group.Conclusions Assessing facial morphology using three-dimensional surface imaging techniques is a convenient and feasible method.The evaluation of sagittal facial convexity and concavity is an indispensable part of facial morphology features assessment.
