Malignant lip tumours are 15% of all head and neck skin neoplasies. They are mainly foun in lower lip, coming from the stratified epithelium. Aetiology factors have been focused on UV-radiation, toxic habits and poor oral hygiene.
We have reviewed 152 patients operated over a 10-year-period, presenting malignant lesions on their lips. We have studied those tumours bigger than 1 cm and with histologic confirmation.
Most common histologic diagnosis was squamous-cell carcinoma situated in lower lip. There is male predominance, in their seventh decade of life. Most lesions have been present for years and appear on queratous injuries. Only 20% present detectable lymph nodes at the moment of diagnosis, however prophylactic lymphadenectomy is carried out on 40%. All reconstructive techniques have been loco-regional flaps.
The reconstructive procedure changes depending on the localization of the tumour, its size and the depth. Good results can be achieved with these flaps. However certain degree of microstomy may result. Prophylactic lymphadenectomy improves prognosis, and lower the mortality rate.
