Hypoglossal canal: an osteological and morphometric study on a collection of dried skulls in an Italian population: clinical implications

Table 3 With the averages of the measured parameters of the right and left hc and the significance of the differences

Parameters	MEAN (mm)	SD	Med	Min Max	P-values	Statistical significance
Length of right HC	8,67	1,86	8,66	4,65 14,69	0,25	Not significant
Length of left HC	8,26	1,67	8,24	5,51 14,58	0,25	Not significant
Ex end diameter right Hc	6,33	1,40	6,16	4,06 12,67	0,71	Not significant
Ex end diameter left Hc	6,44	1,59	6,20	4,16 12,96	0,71	Not significant
Int end diameter right HC	6.03	1,42	5,69	3,34 13,06	0,53	Not significant
Int end diameter left Hc	6,21	1,43	5,90	4,15 11,04	0,53	Not significant
Distance I-A right	10,65	1,48	10,87	6,5 13,62	0,47	Not significant
Distance I-A left	10.88	1.70	11,10	7,07 14,20	0,47	Not significant
Distance I-P right	11,11	1,58	11,08	8,19 15,23	0,052	Almost significant
Distance I-P Left	10,51	1,47	10,35	7,67 13,57	0,052	Almost significant
Distance I-I right	7,85	1,73	7,77	3,25 11,64	0,22	Not significant
Distance I-I LEFT	7,45	1,52	7,38	3,85 11,54	0,22	Not significant

The data of each parameter of the right HC were compared with those of the left HC using a Student's t-test
The I-P distance is greater to the right than to the left and the difference comes very close to significance
