  We have classified the cauliflower ear into different types according to the zone and the degree of deformity. One major group is deformity without change in the outline of the ear, and this is divided into four subgroups according to the zone. All of these subgroups can be treated by shaving the deformed cartilage through suitable incision lines. For deformities accompanied by a skin deficit, a postauricular skin flap should be used. The other major group is deformity accompanied by a change in the outline of the ear, which is divided into two subgroups. If the ear is rigid, a conchal cartilage graft is used. If the structural integrity of the ear is poor, costal cartilage is used to provide rigidity. (C) 2002 The British Association of Plastic Surgeons.

• New treatment of a visible linear scar in the scalp: multiple hair-bearing flap technique

  Scars on the scalp have no hair, and can be conspicuous even when narrow. Alopecia, especially in the whorl of hair at the back of the parietal region, is very difficult to camouflage. We present a new technique using multiple hair-bearing flaps harvested from near the area of alopecia, each flap including 10-15 hairs. We treated 24 patients who were suffering from alopecia, with scar sizes ranging from 2 cm to 17 cm in length and from 0.5 cm to 2 cm in width. Between three and 12 flaps per patient were used to complete the treatment. All wounds healed without complications, and satisfactory results were achieved in 20 patients. Hair loss from the flap was rare. The scar could be hidden by the hair immediately after the operation. In four patients, a visible scar remained or was created at the donor site. These patients required a secondary repair. The major advantages of this technique are that the dense hair bundles in the flap are studded here and there in the scar, the scar can be reduced and the residual scar can be hidden by the flap hair. This technique is most useful for the parietal and occipital areas, especially near the whorl of hair. (C) 2002 The British Association of Plastic Surgeons.
