Double lip correction surgery effectively addresses this condition through a simple, straightforward procedure with lasting results. So what exactly is double lip correction surgery? Let's explore the expert's detailed explanation below.
Treatment Principles for Double Lip Correction:
When mucous glands beneath the lip mucosa become enlarged due to various stimuli, they may sag downward under gravity. During speech or smiling, contraction of normal lip muscles exacerbates this drooping and outward flipping of the mucosal tissue, creating the double lip deformity.
Double lips primarily affect the upper lip and are most noticeable during adolescence. This deformity significantly impacts appearance: it remains inconspicuous when the mouth is closed but reveals two distinct lip edges when open. A horizontal groove appears between the lip edges, creating two distinct red lip lines when smiling.
Both thick lips and double lips can be corrected surgically.
Thick lip reduction involves making an oblong or serrated incision at the junction of the vermilion border and mucosa on both upper and lower lips, removing a strip of oral mucosa and muscle tissue according to the degree of lip thickness. The incision is then directly approximated and sutured to thin the lips. The surgical scar is concealed inside the mouth, yielding satisfactory results.
The treatment principle for double lips involves partial excision to restore the vermilion border to a normal contour. Two surgical techniques exist:
The "elliptical excision method" and the "transverse-longitudinal rhombic excision method." The rhombic excision involves making an elliptical incision along the edge of the double lip, excising mucosa and submucosal tissue in a wedge shape, then layered suturing of the wound.
The transverse-longitudinal wedge resection involves placing a suture on each side of the upper lip to retract the tissue outward. Transverse wedge incisions are made at the protruding areas of the double lip on both sides, while a longitudinal incision is made along the midline. Excess mucosa and submucosal tissue are excised, followed by layered suturing.
