CD73 in aggressive basal cell carcinoma
This is a retrospective review looking at levels of CD73 in aggressive basal cell carcinomas (BCCs) that invade the orbit. Eleven patients who underwent orbital exenteration for invasion by BCCs were compared with 10 matched controls who had simple nodular...Auricular reconstruction: flip-flop flap
Describing an approach to the straightforward and reliable flip-flop axial flap for reconstruction of the conchal bowl subunit of the auricle. The ‘flip-flop’ flap describes an axial subcutaneous island flap lying between the auricular sulcus and mastoid process. The flap...3D photography in facial rejuvenation
