Table 3.

Results of the Fisher’s exact test (by category of pathology) applied to data from otosclerosis subjects implanted with a straight electrode. The p-value is the probability of obtaining the distribution (across subjects) of the pathology shown in Table 2 and the distribution of FNS shown in Table 1 by chance alone if there is no relationship between the pathology and FNS.

Structures altered by otosclerosis	p-value
All bone between UBTC and FNC, and UBTC	.005
endosteum and FNC endosteum
Bone adjacent to FNC and FNC endosteum	.200
IAC	.076
Modiolus	0.190
RW obliteration	.133
Cochlear endosteum	.197

UBTC: Upper basal turn of cochlea; FNC: Facial nerve canal; FNS: Facial nerve stimulation; IAC: Internal auditory canal
