RESUMO
Los labios comprenden una estructura móvil, formada por una capa muscular cubierta externamente por piel, internamente por mucosa y entre ambas una zona de transición, el bermellón. Debido a su ubicación, el labio inferior recibe radiaciones actínicas directamente, y ésta es la causa por la cual la incidencia de tumores es mayor que en el labio superior. Los labios desempeñan importantes funciones, por lo que la reconstrucción ofrece un gran desafío al cirujano plástico, el cual debe conservar tanto la función como el aspecto estético. Se presenta paciente de sexo masculino, 62 años, que presentaba carcinoma espinocelular de labio inferior, ulcerado, fondo granulante, bordes evertidos, duropétrea, de 3 cm, que afectaba el 70 % del labio e incluía la comisura derecha, sin adenopatías palpables, de 3 años de evolución.
Lips comprise a mobile structure, composed by a muscular layer covered by skin in the outside and mucous in the inside. Between covers there is a transition zone, the vermillion. Due to its localization, the lower lips is exposed to direct sunlinght radiation, and that is the main reason why it has a higher incidence in skin malignancies than the upper lip. Lip reconstruction after excision of malignancies is a challenge for the Plastic Surgeon, mainly because of the important functions of the mouth. The goal is to remain the preservation of those functions as well as restorting the aesthetic unit aspect. A 62 years old male is presented. The patient acussed a history of the tumor, a squamus cell carcinoma of the lower lip, of 3 years. At the admission, the patient showed a 3 cm. firm tumor involving 70 % of the lower lip, including the right commissure. An ulcer with granulation tissue and raised outlining was evident. No local or regional adhenopathies were found at the moment of the admission.
