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.

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.

Reconstruction based on the aesthetic subunit principle has yielded good aesthetic outcomes in patients with moderate to severe nasal defects caused by trauma or tumor resection. However, the topographic subunits previously proposed are often unsuitable for Orientals. Compared with the nose in white patients, the nose in Orientals is low, lacks nasal muscle, and has a flat glabella; the structural features of the underlying cartilage and bone are not distinctly reflected in outward appearance. The authors devised aesthetic subunits suitable for Orientals, and they used these units to reconstruct various parts of the nose. The major difference between these units and those presented previously is the lack of soft triangles and the addition of the glabella as an independent unit. The authors divided the nose into the following five topographic units: the glabella, the nasal dorsum, the nasal tip, and the two alae. The border of the nasal dorsum unit was extended to above the maxillonasal suture. The basic reconstruction techniques use a V-Y advancement flap from the forehead to reconstruct the glabella, an island flap from the forehead to reconstruct the nasal dorsum and nasal tip, a nasolabial flap to reconstruct an ala, and a malar flap to reconstruct the cheek. A combination of flaps was used when the defect involved more than one unit. This concept was used for nasal reconstruction in 24 patients. In one patient undergoing reconstruction of the nasal dorsum and in one undergoing reconstruction of the nasal tip, the texture of the forearm flap did not match well, which resulted in a slightly unsatisfactory aesthetic outcome. In one patient in whom the glabella, nasal dorsum, and part of the cheek were reconstructed simultaneously, a web was formed at the medial ocular angle, and a secondary operation was subsequently performed using Z-plasty. In one patient undergoing reconstruction with a forehead flap, defatting was required to reduce the bulk of the subcutaneous flap pedicle at the glabella. However, suture lines were placed in the most inconspicuous sites in all patients, and the use of a trapdoor contraction emphasized the three-dimensional appearance of the nose. The use of these aesthetic subunits for reconstruction offers several advantages, particularly in Oriental patients. Because the nasal dorsum is reconstructed together with the side walls, tenting of the nasal dot-sum is avoided, which prevents a flat appearance of the nose. A forehead flap is useful in the repair of complex defects. Defects of the alae should be separately reconstructed with a nasolabial flap to enhance the effect of the trapdoor contraction and to highlight the three-dimensional appearance of the nose. Candidates for reconstruction should be selected on the basis of nasal structure. The results suggest that these units can also be used in some white patients.
