Reconstruction of extensive ear defects after Mohs micrographic surgery: two case reports

The ear is one of the regions with the highest prevalence of cutaneous tumors. The reconstruction of auricular defects resulting from its excision tends to be complicated, especially when extensive and of the total thickness. We report two cases of reconstruction of surgical defects due to the resection of auricular basal cell carcinomas by Mohs micrographic surgery. One case was reconstructed through an interpolated island flap mobilized from the retroauricular region through the primary defect itself, and the other by retroauricular skin flap with anterior rotation through the primary defect. Both presented satisfactory aesthetic and functional results.
