Abstract: | Background The anterolateral thigh (ALT) perforator flap is a well-described and versatile flap, regularly used for resurfacing and reconstructing soft tissue defects, but it is often too bulky to produce an aesthetically satisfactory result. Although primary thinning of the ALT has been successful in Eastern populations, studies have demonstrated that this may be inadvisable in Caucasians. This is the biggest clinical study demonstrating the clinical safety of primary thinning of ALT flaps in Caucasians. Methods A retrospective analysis was performed between January 2009 and August 2011 on 57 patients (mean age 43) undergoing ALT free flap reconstruction by three surgeons. They were all thinned via sharp dissection using loupe magnification except for 1–2 cm around the perforator by removing the larger fat globules of deep fascia and preserving the superficial fat layer. The resultant flap thickness was approximately 6 mm. Results In 77 % of cases, the flap was used for lower limb, 16 % for upper limb and 7 % for head and neck reconstruction. The mean flap surface area was 124 cm2. There was one flap loss (1.8 %) and three flaps returned to theatre for perioperative complications. Conclusions Careful primary thinning of ALT flaps is safe in Caucasian populations and can achieve improved cosmetic results. Level of Evidence: Level IV, risk/prognostic study. |
