This V Y advancement flap is useful because the procedure does not require any difficult technique, and preservation of the orbicularis oris muscle and the branch of the mental artery and nerve are possible. The vermilion is reconstructed with a tongue flap, with almost no disturbance in the patients speaking or eating and satisfactory cosmetic results. We describe this procedure in two cases.

Squamous cell carcinoma (SCC) occurs frequently on the lower lip and surgical excision is the main treatment. The lower lip area is difficult to reconstruct, and is very complex morphologically and anatomically. Cosmesis requires reconstruction of the infravermilion defect by facial skin of normal texture and colour, in addition to reconstruction of the vermilion border. Various reconstructive approaches for defects of the lower lip have been described, but few address the wide transverse shallow defects. In two cases with wide transverse shallow defects of the lower lip after resection of SCC, a V Y advancement flap was used to replace the skin of the lower lip, and a tongue flap was used to * Corresponding author.

The aim of this study was to assess the efficacy of V Y advancement flap and tongue flap for transverse narrow defects of the lower lip. Operative technique The tumor is resected with a 1 cm margin in an approximately rectangular shape (Fig. 1). The mental V Y advancement flap is designed in the shape of a triangle with its apex inferiorly, at the edge of the mandible. Only the skin and subcutaneous tissue are incised, thus preserving the orbicularis oris muscle, depressor labii inferioris muscle, and mentalis muscle. For upward advancement of the flap it is necessary to dissect the orbicularis oris muscle plane at least 1 or 2 cm lateral to the flap and to dissect subcutaneously the S /$ - see front matter Q 2004 The British Association of Plastic Surgeons.

The flap is advanced upward to the lip defect as an orbicularis oris musculocutaneous flap preserving the oral sphincter. The skin and subcutaneous tissue are sutured in two layers in a Y fashion, joining the remaining vermilion border and the upper end of the flap. Next, mucosal coverage is provided by the tongue flap. A rectangular tongue flap is designed on the inferior surface to fit the vermilion defect. The tongue flap is elevated and inset to vermilion defect. The tongue flap is cut off after 2 weeks and the oral side of the vermilion is sutured. The donor site of the tongue is closed primarily. Case reports Case 1 A 55-year-old woman was admitted with a biopsyproven 2.5!1.0 cm 2 well differentiated SCC situated on the lower lip. For treatment of the tumor, the lower lip from the white lip to the vermilion with normal tissue margins of 5 10 mm was excised. The height of the white lip defect was about 1 cm (Fig. 2(A)). Reconstruction of the white lip defects was performed with a 3.5!4.0 cm 2 triangular musculocutaneous flap. The flap was advanced upward as a subcutaneous pedicle flap and was fixed by joining the remaining vermilion border and the upper end of the flap together (Fig. 2(B)). The vermilion was reconstructed by a tongue flap, which measured 3.5!1.0 cm 2 (Fig. 2(C)). Two weeks later, the tongue flap was divided and the donor site sutured. The follow-up period was 4 years with no recurrence. The lip function was excellent, and dentures were used without any problems (Fig. 2(D)). Case 2 An 81-year-old man was admitted with a 2.5! 1.2 cm 2 well differentiated SCC with submucous induration situated on the lower lip. No lymph nodes were palpable. Under general anesthesia, wide excision of the tumor was performed with normal tissue margins of 1 cm (Fig. 3(A)). The white lip of the lower lip defect was reconstructed with a 4!4.5 cm 2 triangular musculocutaneous flap. A 4! 1cm 2 tongue flap was used to provide mucosal cover (Fig. 3(B)). The tongue flap was divided and the donor site of the tongue sutured after 2 weeks. He had a good aesthetic result and good aesthetic muscle function. He used dentures without any problems during a follow-up period of 15 months (Fig. 3(C)). Discussion Various flap procedures for reconstruction of lower

Successful reconstruction of the lower lip requires certain criteria. The reconstructed lip should be sensate, retain the sphincter or muscle function, oppose its vermilion to the vermilion of the upper lip to make a watertight continent seal, and allow sufficient opening for food and dentures. In addition, it is important to achieve an acceptable aesthetic appearance, that is, complete skin cover and oral lining, and a semblance of the vermilion border. V -shaped or W -shaped defects of up to onethird of the lower lip can be closed primarily without undue tension or distortion of the anatomy with an acceptable reduction of the oral stoma. However, when a defect involving one-third of the lower lip is created, reconstruction can be planned by the use of local flaps or free tissue transfer. Lip switch techniques are recommended for defects ranging between one-third and one-half of the lower lip size. For defects larger than one-half of the lower lip, the technique of advancement of the cheek tissue by the Webster-Bernard approach is widely used, but the tension of the closure has frequently resulted in a tight lip that function poorly. A more satisfactory procedure for defects of this magnitude is the Karapandzic rotation flap,

Some local flaps retain motor innervation, 1,2 but frequently, the transposed tissue is denervated and therefore does not exhibit adequate sensation or immediate normal function of the oral aperture, both of which are desirable. For transverse narrow defects of the lower lip, the platysma musculocutaneous flap with a triangular skin island and the mental neurovascular V Y advancement island flap from both sides of the chin were reported. 3,4 Our reconstructive procedure is simple upward advancement of tissues from the chin as musculocutaneous flap, thus covering the lip defect and preserving the muscles for sphincteric function. With the advancement of V Y flaps, a lip curtain of adequate dimensions is achieved. The lip height of our patients was within normal limits, and good vestibular access was achieved and proved suitable for use of dentures. This mental V Y advancement flap is suitable for the transverse narrow defects in the lower lip. Reconstruction of the vermilion border can be achieved with tattooing, 5 uni- or bi-pedicled mucosal flaps, 6,7 musculomucosal flap, 8 lip-sharing, 9 simple grafting, 10 or tongue flaps. 11,12 Our reconstructive alternative for the vermilion is the use of a flap raised from the ventral surface of the tongue. This procedure has given us very good aesthetic results. This combination serves to preserve the full transverse width of the oral commissure. Its disadvantage is that it is necessary to maintain the tongue attached to the lip for a period of 2 weeks, and then the pedicle is divided in a second surgical stage. The patient must tolerate an open mouth and bite-blocks. This vermilion reconstruction does not provide immediate sensory innervation, but recovery of the sensory innervation, at least to a protective level, can be expected. The patients are provided with a generous and functional oral aperture that allows oral hygiene, denture placement, and oral feedings without any anatomical constriction. The orbicularis oris muscle remains sufficient, and the functional and aesthetic requirements of a dynamic lower lip can be met by this relatively simple procedure without any significant donor site morbidity. Our results indicate that the combined tongue flap and V Y advanced flap is
