To describe a new technique of surgical treatment of the lip commissure or buccal mucosa carcinomas, where we use local flaps (skin, buccal mucosa) of the sliding type.According to the current technique, the ectomy ranges horizontally and in a cuneiform shape towards the side of the buccal cavity, and in the whole thickness of the layer (skin - mucosa), where the neoplastic focus is enclosed.The difference in our technique consists of the following: To the vertical bi-cuneiform part of the wound a horizontal cuneiform part (with the top showing upwards) is added, with extent and width analogous to those of the cancerous injury (tri-cuneiform ectomy). The width of the gap across its horizontal part is larger on the side of the mucosa (continuous line), compared to the one along the side of the skin (punctuated line), since the mucosa, as a more versatile tissue, can be sutured easily, in contrast to the buccal skin, which is of greater thickness and shows lack of versatility, so that it can be pulled on with difficulty in order to be sutured. The planning of the injury, according to our described technique, facilitates the broad ectomy of the intraoral injuries in the area of the lip commissure and the buccal mucosa, with immediate suture of the flaps (buccal and skin gap), and the occlusion of the wound by primary intention.Using this specific technique, in the cases of extended injuries infiltrating the skin or the subcutaneous tissue, the harming use of transposition (sliding or free) flaps is avoided. |
