To discuss and report the operative techniques for harvesting perforator-based chimeric flap in anterolateral thigh region and the advantages for head and neck reconstruction after en bloc resection.


A retrospective review was performed of perforator-based chimeric anterolateral thigh (ALT) flap for head and neck reconstruction since December of 2007 to March of 2011. 66 perforator-based chimeric flaps were harvested including a skin paddle and a muscular flap supplied by one mother pedicle-descending branch of lateral circumflex femoral artery(d-LCFA). 32 flaps were used for the mobile tongue and floor of mouth reconstruction, 30 flaps for base of the tongue and parapharyngeal walls, two for the buccal skin, one for hemimandible and one for parotid. The muscular flap were used to eliminate the dead space of submandibular area. Flaps size ranged from 7cm±4cm to 16cm±7cm and muscular flap was 3cm±4cm approximately. The complications and functions of both donor and recipient sites were recorded and the operative techniques of perforator-based chimeric flap elevation were generalized.


All 65 flaps survived completely and the total survival percentage was 98.5%. Only one flap failed and was removed 5 days postoperatively. No complications(fistula, infection, hematoma, seroma et al) were observed in recipient and donor sites. Two anteromedial thigh flaps (AMT) were used for reconstruction due to no sizable perforators in the ALT region. All cases were followed up for 0.5-3 years. The flaps didn't atrophy after six months and the contour was satisfactory. The functions of speech and swallow were recovered well. All the donor sites were closed primarily and the scar was not obvious. The leg's function recovered well.


Using a combination of retrograde and antegrade dissection is a safe and versatile method for harvesting a perforator-based chimeric flap. A chimeric flap including multiple components can meet the requirements of three-dimensional reconstruction. Perforator-based chimeric anterolateral thigh flap is one of the best choices for complex head and neck reconstruction after en bloc resection.
