Reconstruction of acquired perineovulvar defects: a proposal of sequence.

Acquired perineovulvar defects are usually the result of excision of vulvar intraepithelial neoplasia (VIN) or invasive squamous cell carcinoma. Because both VIN and vulvar carcinoma have a tendency toward local recurrence, future reconstructive options should be reckoned with during treatment of the primary and all subsequent (pre-) malignant perineovulvar lesions. Hence, a proposal of sequence of reconstructive options for these defects is called for. In cases where local skin flaps suffice, these are preferably designed in such a fashion as not to sever the branches of the internal pudendal vascular system. In cases where either a pudendal thigh flap or an infragluteal flap may be used to close the perineovulvar defect, the pudendal thigh flap is to be preferred to preserve the infragluteal flap for future use. Only when these flaps no longer are available or sufficient to cover the defect should the gluteal thigh flap be applied. The use of myocutaneous flaps is rarely indicated to close isolated superficial perineovulvar defects.
