Abstract

CASE REPORT

A 56-year-old woman presented with a 1-year history of a raised erythematous lesion that extended from canthus to canthus across her nasal bridge (Fig. 1). She had a history of hypercholesterolaemia but was otherwise fit and well. An incision biopsy was arranged which revealed changes consistent with chronic inflammation on a background of xanthelasma. Despite this benign diagnosis, the patient insisted upon surgical excision as she had become extremely conscious of the lesion to the extent that she would avoid leaving the house. After appropriate patient counseling with regard to the possible complications of surgical management, the patient was scheduled for marginal excision and immediate reconstruction. Under general anesthesia, the lesion was excised en bloc and sent to histology. Bilateral nasolabial V-Y island flaps were raised and advanced cephalad and a glabella V-Y island flap was raised and advanced caudal to complete the ‘like-for-like’ subunit reconstruction (Figs. 2, 3). In this case, it was not necessary to skeletonise the perforators of the angular artery that supplied the nasolabial flaps to achieve the desired advancement; however, when required to do so, we never hesitate to skeletonise these perforators. The donor scars were camouflaged within the nasolabial folds and vertical wrinkle lines of the glabella region, no complications were encountered, and an aesthetic result was observed at 12 months follow-up (Fig. 4). Histology confirmed xanthelasma.

DISCUSSION

Many techniques have been described for the reconstruction of facial soft-tissue defects. An early description of the subunit reconstructive concept was in 1965 when Gonzalez-Ulloa et al1 reported on the use of regional aesthetic subunits in the successful reconstruction of nasal and forehead defects. Since this time, many authors have refined and modified various techniques based on the subunit concept in the search for optimal aesthetic results in facial reconstruction. In particular, in 1985, Burget and Menick2 popularized the subunit principle with regard to possibly the most complex aesthetic facial structure of them all, the nose. By dividing the nose into nine specific subunits, they demonstrated that the best cosmetic results were achieved through reconstructive techniques that respected the individuality of these parts. Moreover, in a histological study carried out in Australia in 2010, Rahman et al3 demonstrated that based on pilosebaceous unit density and dermal/epidermal thickness, the best histological match for a given facial defect is likely to come from an adjacent subunit. This is not a new concept, indeed Gillies and Millard4 were well aware of this in the 1950s when they stated that “the next nearest skin is the next best skin.” Indeed, the marriage of old and new concepts often achieves the best results, and with this in mind, we feel that the combination of the aesthetic subunit principle and the perforator concept5 can help in achieving optimal aesthetic outcomes when dealing with facial reconstruction. Moreover, based on the perforasome principle,6 one can safely and confidently skeletonise the perforators of the angular artery when raising a nasolabial flap and thereby facilitate tension-free advancement of the nasolabial tissue. This approach avoids the transfer of tension onto the surrounding aesthetic subunits and prevents any distortion of these parts. Indeed, the disadvantages of many of the classically described local flaps used in facial reconstruction are a limited arch of rotation and the transfer of tension onto adjacent subunits.

CONCLUSIONS

In summary, by respecting the aesthetic subunits of the face along with an awareness of the perforasome concept, a very favorable one-stage aesthetic result was achieved in this case.
