Reconstruction following cartilage excision can be difficult with contour deformities posing a potential problem. In this case, there was not enough redundant skin in the posterior auricular sulcus for a transposition flap. Before now, the trap door flap has only been described for anterior pinna defects. It had to be modified slightly from the traditional trap door flap in order to reconstruct posterior pinna defects. The posterior auricular area blood supply has been well documented [4] and as a result flap loss is exceedingly rare [3]. McInerney et al. [3] reported on 45 patients with anterior pinna and conchal defects who had trap door reconstruction. They found the flap to be very reliable, producing a good cosmetic outcome. The flap provides a good colour match as it replicates the contour of the ear very well. We feel that the trap door flap should now be considered as a reconstructive option when excising skin malignancies on the posterior aspect of the pinna especially when there is a paucity of skin for a transposition flap. It is an extremely safe and effective flap with an excellent and predictable outcome.
