Background:
Perforator flap surgery has gained great popularity in the last decade because surgeons can prepare freestyle flaps in anywhere on the body if they find a perforator supplied to the flap. One of the basic principles of reconstructive surgery is that superior results can be obtained for color and texture match if immediately adjacent soft tissue is used to repair a defect. V-Y advancement flaps are used successfully based on this principle, but the degree of mobility of a V-Y advancement flap is dependent on the laxity of the underlying subcutaneous tissue. This is an important disadvantage of traditional V-Y advancement flap and limits its use.
Methods:
We used V-Y advancement flaps as perforator-based to overcome mobility restriction problem. The authors used 26 perforator-based V-Y advancement flaps in 24 consecutive patients for coverage of defects located at sacral (4), thigh (6), abdominal wall (3), inguinal (3), back (4), leg (2), and trochanter (2) regions. There were 14 female and 10 male patients with a mean age of 48.3 years (range, 22-70 years).
Results:
The patients were followed up for a mean period of 14.2 months (range, 9-21 months). The size of the defects ranged from 3 x 5 cm to 15 x 20 cm. All flaps survived completely (92.4%) except 2 in which one of them had undergone total necrosis and the other had marginal necrosis. Fifteen flaps (57.6%) were elevated based on 2 perforators, 7 flaps (26.9%) were used with only one perforator, and the remaining 4 (15.5%) had 3 perforators.
Conclusions:
Perforator-based V-Y advancement flaps are safe and very effective for coverage of defects in which closure is impossible with a standard V-Y advancement flap. Dissection of the perforator or perforators offers remarkable excursion to the V-Y flap with minimal donor site morbidity. These axial pattern flaps can be used successfully with good esthetic and functional results at various regions of the body if there is any detectable perforator.
