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.
