However, the correlation between the small lateral semi-circular canal (LSCC) and SNHL is controversial.<\/jats:p>\n <\/jats:sec>\n \n Purpose<\/jats:title>\n To determine whether there is a correlation between the two using CT-based measurement.<\/jats:p>\n <\/jats:sec>\n \n Material and Methods<\/jats:title>\n We retrospectively reviewed the high-resolution CT images of the temporal bone obtained from consecutive patients. A total 136 ears of 68 patients (25 men and 43 women; age range 20\u201385 years, mean 49.8 years) were included in this study. Patients who were clinically suspected to have otosclerosis were also excluded. Two radiologists independently measured the width and cross-sectional area of the bony island of LSCC. We evaluated the correlation between LSCC bone island width or cross-sectional area and hearing level in all cases using Pearson correlation co-efficients. In addition, we compared hearing levels among the patient group with normal-sized LSCC (\u2267mean-SD), small LSCC (<mean-SD) and very small LSCC (<mean-2SD) as defined by the width and cross-sectional area of the bony island using Student's t-test.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total 136 ears of 68 patients (25 men and 43 women; age range 20\u201385 years, mean 49.8 years) were included in this study. No significant correlation was shown between LSCC bony island width or cross-sectional area and hearing level (P\u2009>\u20090.05). No significant difference in hearing levels were found among groups of the normal-sized, small and very small LSCC (P\u2009>\u20090.05).<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n We
