Purpose
Because the skin of anteromedial thigh region usually is thinner, pliable, hairless it can be preferred based on the requirements of the recipient site. In this way more information is necessary about the perforators of anteromedial thigh region. The aim of this cadaveric study was described to provide useful knowledge about localizations and number of anteromedial thigh perforators.
Methods
Study was carried out on 16 lower extremities of 9 cadavers. The area in anteromedial aspect of the thigh searched for perforators was defined between the anterolateral border of sartorius and the posterior border of gracilis. The diameters of the dissected perforators were measured and the locations were documented.
Results
A total of 204 perforators were dissected in 16 lower extremities. The majority of musculocutaneous perforators were from gracilis (24 of 37) and there were at most 3 musculocutaneous perforators arising from gracilis muscle. 167 septocutaneous perforators were identified. Origin of all perforators was determined as 52 from deep femoral artery, 25 from proximal part of femoral artery and 127 from distal part of femoral artery and their branches. Perforators with the largest diameter were the ones arising from the intermuscular septa between the adductor (longus and magnus) and sartorius muscles. The mean diameter of the perforators was 0.75 ± 0.11 mm and ranged between 0.61 and 0.96 mm.
Conclusions
The septocutaneous perforators of the anteromedial aspect of the thigh are as much important as the musculocutaneous perforators and all they are with adequate to perform anteromedial thigh flap. This study provides numerical overview, useful perception about the localization of the perforators of the anteromedial aspect of the thigh and detailed anatomical basis for anteromedial thigh flap to be an important alternative.
