Does osteotomizing the lower border of the mandible affect the lingual split pattern in a sagittal split ramus osteotomy?

Table 3 Distribution of lingual cortical fracture patterns in the two groups

	Lingual cortical fracture pattern^a, No. (%)					P Value
	LSS1	LSS2	LSS3	LSS4	Total
BSSO with inferior border osteotomy	10 (25)	6 (15)	4 (10)	0 (00)	20 (50)	0.04
BSSO without inferior border osteotomy	6 (15)	2 (5)	9 (22.5)	3 (7.5)	20 (50)
Total, No. (%)	16 (40)	8 (20)	13 (32.5)	3 (7.5)	40 (100)

^aAccording to the lingual split score by Plooij et al. [19], Fisher’s exact test
