Human lip crosses outwards, show one part mucous membrane, if mucous membrane is beyond the mark outside protruding can create labial heavy panel. Alleged " thick lip " it is to point to, male labrum ply exceeds 9 millimeter, labium exceeds 10.5 millimeter; Female labrum exceeds 8 millimeter, labium exceeds 9 millimeter.
If the mucous gland of lower part of labial mucous membrane stimulates proliferous hypertrophy as a result of a variety of reasons, there still can be the tendency that falls downward below gravitational action. When talk or smiling, the labial flesh systole of normal place forces straining to be in mucous membrane to organize flagging evaginate accentuation, form the deformation that weigh a lip. Heavy lip basically sees at labrum, behave in adolescence more most apparent. This deformation is very big to appearance influence, when closing a mouth, deformation is not shown, when the mouth, see two lips reason. There is one horizontal channel between two lips predestined relationship, two clear red lips appear when laughing.
Thick lip and heavy lip all can give through hairdressing operation correctional.
Thick lip repairs light method, it is to be in skin of fluctuation lip red lip and mucous membrane boundary, inspect form of shuttle of labial large degree or zigzag excision mucous membrane of an oral cavity and muscle, next cut of suture of direct hook in, thickening lip changes thin. Scar of this operation cut concealments inside the mouth, effect ideal.
Weigh remedial principle of the lip, it is to make partial excision, make red lip returns to normal appearance. Art form has two kinds. "Shuttle form excises a law " and " form of horizontal Zong Leng excises a law " , law of arris form excision is an edge the Zhou Yuan that weigh a lip makes shuttle form cut, wedge excises the organization below mucous membrane and mucous membrane, next statified suture cut. Law of excision of form of horizontal, vertical shuttle is in labrum two side seam stitch each, drawing two lines make labrum evaginate. In two emphasize particularly on the lip highlights place to make cut of form of one horizontal shuttle each, and central line ministry makes vertical form cut, after excision is organized below redundant mucous membrane and mucous membrane statified suture.
