epicanthal surgery

Oriental nose is relatively flat, so it is very common for newborn babies in China to have internal ecdysis. However, most of them develop with the bridge of the nose, and the internal ecdysis disappears or is relieved. Generally, no surgery is needed. Only those who have obvious skin after puberty need surgery. Congenital internal ecdysis, due to the vertical tension of the internal iliac crest, causes a skin fold in the medial malleolus. The formation of the internal ecdysis is not due to the excessive level of the internal iliac crest to the skin, so the resection of the medial temporal skin can not correct the molting. Reasonable correction of suede surgery is to use the flap indexing method to reduce the vertical skin tension to achieve corrective effect. Since the internal molting can disappear or reduce with age, surgery should be performed after puberty. However, those who have a combination of ptosis and small cleft palate, especially those with a reverse type of internal ecdysis, can undergo surgery before the age of 2 years. Treatment of diseases: congenital cleft palate syndrome Indication Internal suede is a cosmetic correction for cosmetic purposes. Preoperative preparation 1, the patient should be explained before surgery, surgical scars can be seen locally, especially within 6 months. 2, the normal internal hemorrhoids position should be 1/2 pupil distance, that is, positioned at the midpoint of the center of the bridge of the nose and the center of the pupil. Surgical procedure Yv correction 1. Mark the normal internal hemorrhoids first and measure the distance that needs to be shortened. 2. The inner ankle is made into a y-shaped skin incision, and the arms of y are substantially parallel to the upper and lower condyles. The long axis of y is in the medial condyle plane, from the nasal side of the internal condyle to the nasal side, and the length of the incision is determined according to the degree of the internal epidermis. 3. After the subcutaneous sneak separation, the y-shaped incision is made into a v-shaped suture. If the internal suede is more obvious, the local tension is larger when the v-shaped suture is used, and a suture can be made under the skin before suturing. Blair correction 1. Make a y-shaped skin incision in the medial malleolus, and make a branch incision at the upper and lower ends of the incision to the inner ankle to make four triangular flaps a, b, c, and d. 2. The two flaps a, b, c and d are staggered and transposed, and the skin incision is sutured intermittently. Stallard correction 1. The entire length of the sacral sacral fold is a curved skin incision. A substantially vertical skin incision is made at the upper end of the incision. The skin incision was made from the arc-shaped incision to the upper side of the nose 4 mm below the inner ankle. The incision was terminated at a level of about 4 mm from the horizontal incision of the incision. At this time, the skin incision was z-shaped. 2. Free up and down two triangular flaps for staggered indexing. Intermittently suture the skin incision. Speath correction A curved skin incision ab along the inner suede edge. The skin incisions ac and bd which are almost perpendicular to the inner and lower rims of the upper and lower rims are formed at both ends of the slit, and two triangular flaps a and b are separated. At both ends of a and b, the flap is pulled up to the nose and under the nose, so that the inner ankle is completely exposed, and the proper position is marked with gentian violet, ie, e and f points. The branch incision 0e, 0f was made to e and f at the central 0 point of the incision of the internal sac, and the subcutaneous tissue was separated into two triangular flaps c and d. The two skin flaps a and c and the two flaps b and d are interdigitated and transposed, and the skin wound edge is sutured intermittently. Mustard correction 1. Use gentian violet to mark the original sputum and normal sputum position p1, p2. The incision line oa, ob, which is 60° in the oblique direction of the squat and the underarm, is oa=ob=p 1p2 minus 2 mm. Then, the 45° slit lines ac and bd are made to the nose side at both ends of a and b, and the length thereof is equal to oa and ob. P2 is the skin incision line p2e, p2f parallel to the upper and lower temporal margins, and the length is also equal to oa, ob. 2. Cut the skin and the orbicularis muscle along the incision lines above, taking care to avoid damage to the internal iliac vein. The medial malleolar ligament was cut, and the suture was made at the rupture end of the temporal side, and the medial malleolar ligament was fixed at the p1 or slightly upward lining of the iliac crest. 3. Free the above four flaps, and interdigitate the a pair of flaps a, c and b, d. Trim the excess skin at the incision and suture the skin incision intermittently. Lower suede l-shaped skin resection correction 1. At the upper part of the inner iliac crest, 2mm below the lashes under the rim of the rim, make a skin incision parallel to the rim, and the incision should not be shorter than the central part of the lower jaw. According to the condition of the lower suede, the width of the skin that should be removed from the inner iliac crest is determined, and the skin of the upper edge of the incision of the lower iliac crest is pulled downward in the nasal direction, until the lower epidermis disappears, and the lashes return to the normal position. Mark the points with gentian violet. A skin incision is made from the marked point to both ends of the original skin incision. Cut off the l-shaped skin at this place. 2. Make a little sneak separation to the surrounding subcutaneous tissue. Intermittently suture the skin incision.
