CLASSIFICATION DEFECTS IN THE LOWER LIP

Abstract

The systematizing of defects of the lower lip following resection helps to choose the optimal choice of the cheiloplasty. We have analyzed the patients group including 144 reconstructions of lower lip. We have worked out the classification of the defects in the lower lip. It is adapted to the modern TNM-staging of malignant tumors. The defects following T1-tumor excision are corresponding to less than 1/3 of lip, the defects following T2-tumor excision are corresponding to 1/3-1/2 of lip, the defects following T1-tumor excision are corresponding to more then 1/2 of lip. There are included the location of defects, tissue conditions, time of reconstruction and defect advance.
