Inverted V-Y advancement Epicanthoplasty

Point A is marked in the apex of the caruncula fornix just near the skinemucosal junction while the medial semilunar skin is pulled medially to expose the lachrymal lake. Point B is located at the new desired medial canthus and is projected onto the surface of the medial semilunar skin when in the natural state of tension. Point C is located at the supralateral edge of the semilunar skin by making the length of AC equal to that of BC. Lines AC, BC and AB form a vertical inverse V-shaped skin flap. Point D is on the subciliary line, the length of AD can be adjusted by the extension of the inverse V-shaped skin flap.

the vertical V-shaped skin flap is elevated by sharp dissection in the plane superficial to the orbicularis oculi muscle. The excision of the underlying orbicularis oculi muscles should be individualised, continuing to undermine the base of the V-shaped flap. The vertical inverse V flap was released fully and retracted to the inferior area of “bd” line. Points B and A are sutured together on the medial canthus. The tip of the V flap superior to the level of line BD is trimmed.

palpebral margin incision Epicanthoplasty
Wen Chen 2009年
Point A was marked 1 mm medial to the lacrimal lake. Extending from point A, two lines along the ciliary margins were marked. The lengths of AB (supraciliary) and AC (subciliary) were made 5 mm and 2 mm. Incisions were made along AB and AC. By cutting and dissecting the dense connective tissue located between skin and orbicularis oculi muscle in the medial canthal area. Double eyelidplasty was then performed. After the double eyelidplasty procedure, the end point of the double eyelid fold in the medial canthus was marked as A’.
F.C. Li
Point a is marked on the edge of the epicanthal fold at the level of the mid-caruncle. From point a, a horizontal line is drawn medially on the outer surface of the epicanthal fold up to point b. the nasal skin is pulled medially to completely expose the lacrimal lake. From point a, two lines are made. The line on the upper eyelid corresponds with the planned line for the double eyelid fold. The line on the lower eyelid locates along the lower eyelid border.

内眦赘皮的影响
内眦赘皮是内眦角前方呈斜向或 垂直向分布的半月形皮肤蹼状皱 襞，在亚洲人群中发生率约为 50%。 内眦赘皮使正常内眦角被掩盖， 眼裂变短，两眼间距过宽，严重 影响眼部的美观。 重度内眦赘皮遮挡部分视野。
