OBJECTIVE: To provide an ideal method for repairing the circular cicatricial contracture of thigh. METHODS: Deep inferior epigastric perforator (DIEP) island flaps was elevated based only on the deep inferior epigastric artery and vein and transferred to cover the thigh wound after scar had been resected. RESULTS: Four DIEP island flaps was applied clinically and all flaps survived. The size of the flaps ranged from (8 cm x 28 cm) to (11 cm x 32 cm). Venous return and edema had been obviously improved postoperatively. There was no abdominal weakness and hernia in the donor sites. CONCLUSION: DIEP flap not only retains the advantages of TRAM flap such as good blood supply and rich tissue volume, but also preserves the integrity of the rectus abdominis muscle. DIEP island flap is a good material for repair of the circular cicatricial contracture of the thigh.
OBJECTIVE: To provide anatomical bases for dorso-ulnar aspect of mid-hand reverse flap. METHODS: After red latex was infused into the arteries of 40 sides of adult cadava upper limbs, the origin, course, branches, distribution and distal anastomosis on the dorsal carpal branch of ulnar arteries were observed. And the mid-hand flap transfer was used to repair two cases of soft tissue defect (ranged 4.5-5.0 cm x 2.0-3.5 cm on ring and little fingers). RESULTS: The dorsal carpal branch begins with ulnar artery (3.9 +/- 1.2) cm above the pisiform with diameter of (1.3 +/- 0.2) mm, and branches off into ascending and descending branches. The descending one is the continuing of dorsal branch, it crosses the ulnar edge of the fifth metecarpal bone and anastomizes with the digital artery of little finger or hypothenar branch of deep palmar (accounted for 70%). While the other ascending branch with the former two branches formed anastomosis accounts for 30%. The two cases got healed in one-stage. The function of fingers recovered after 3-4 month follow-up. CONCLUSION: The reverse flap of dorso-ulnar aspect of mid-hand is available to repair the soft tissue defect on dorsum of hand with neighbor finger.
In six cases, the soft tissue expander was instituted as a pretreatment for obtaining a modified frontal cutaneous island flap with the superficial temporal artery in the repair of skin defects of face. The postoperative results in these 6 cases were satisfactory. This method was safe and effective, and provided a satisfactory restoration of outward appearance from facial defects, particularly the defects of palpebra and nose. The operative procedure of making the frontal skin flap was described, and its advantages and disadvantages of the operation and its indications were discussed.
In order to study the feasibiliy of the insular skin flap of the nasolabial groove with the retrograde superior labial artery, 8 adult cadavers were dissected and the relation between the superior labial artery and the skin of nasolabial groove was observed. The result revealed that superior labial artery was one of the branches of the facial artery and could be found in every cadaver. The diameter of the artery was 0.8 +/- 0.1 mm and the length was about 90 mm. The left and right facial arteries were connected with each other in the mid-line in the formation of the arcuate artery. The arcuate artery lay within the submucous tissue beyond the vermilion border about 6 mm. The concomitant veins were constant. If the facial artery being sectioned was beyond its initial site of superior labial artery, the skin of nasolabial groove on the same side could receive blood supply from contralateral supperior labial artery. The conclusion was that the insular skin flap of the nasolabial groove with the retrograde superior labial artery could be used in patients, because it had support from anatomical research.
Objective To explore an effective method to repair penile-scrotal or perineal hypospadias in one stage with prepuce island flap.Methods Different prepuce island flaps were designed according to thedifferent pathological anatomy of the penile-scrotal or perineal hypospadias. The prepuce island flaps were thus translocated and sutured to form the urethra.Thirty-one cases of hypospadias (21 cases of peinil-scrotal type, 10 cases of perineal type) were repaired with prepuce island flap.The biggest length and the width of the prepuce island flapwere 7.5 cm and 1.5-1.8 cm respectively.Results All the cases resulted in a good contour of the penis and a normal anatomic position of urethral meatus without any redundancy or tortuosity.The urination was perfect and acceptable.Conclusion One stage repair of penilescrotal or perineal hypospadias with prepuce island flap can be considered as an acceptable effective surgical technique.
