4. Fig. 3
‘Fish-shaped’ incision or y closure. The lateral edge of the mastectomy wound, Point B, is stitched medially, usually at the anterior axillary line. This then creates 2 limbs, C and D where the redundant skin is excised, resulting in a final ‘fish-shaped’ or Y scar with elimination of the lateral dog ear.

9. Fig. 8
‘L’ technique involving 2 oblique incisions with an optimal distance (A) of 2–3 cm between them at the axilla and a third horizontal incision in the axillary fold. The final result is an inverted ‘L’ scar with elimination of the lateral dog ear.
