Dimensions of the triangle of Koch.

Dimensions of the triangle of Koch varied among the patients. The aim of this study was to present the dimensions of the triangle, and to compare the data obtained directly by post mortal measurement, using two different methods, and indirectly using mathematic formulas. The examination was performed in two independent groups consisting of 50 specimens each. Results showed that the mean value of area of the triangle of Koch obtained by the first type of post mortal measurement was significantly different from the mean value obtained using mathematic formulas (261.65 +/- 52.30 mm2 vs 116.74 +/- 13.20 mm2; p=0.00; p<0.05). But the mean value of the second type of the measurement was very similar to the mathematically obtained data (126.33 +/- 23.71 mm2 vs 116.74 +/- 13.20 mm2; p=0.278; p>0.05) (Fig. 1, Ref. 10).
