Radiographic Measurement of Cochlear in Sudanese Population

4/30/2021 This study aimed to determine the measurements of the cochlea among healthy subjects and hearing deafness subjects using a High Resolution Computed Tomography (HRCT). A total of 230 temporal bone HRCT cases were retrospectively investigated in the period spanning from 2011 to 2015. Three 64-slice units were used to examine patients with clinical complaints of hearing loss conditions at three Radiology departments in Khartoum, Sudan. For the control group (A) healthy subjects, the mean width of the right and left cochlear were 5.61±0.40 mm and 5.56±0.58 mm, the height were 3.56±0.36 mm and 3.54±0.36 mm, the basal turn width were 1.87±0.19 mm and 1.88 ±0.18 mm, the width of the cochlear nerve canal were 2.02±1.23 and 1.93±0.20, cochlear nerve density was 279.41±159.02 and 306.84±336.9 HU respectively. However, for the experimental group (B), the mean width of the right and left cochlear width were 5.38±0.46 mm and 5.34±0.30 mm, the height were 3.53±0.25 mm and 3.49±0.28mm, the basal turn width were 1.76±0.13 mm, and 1.79±0.13 mm, the width of the cochlear nerve canal were 1.75±0.18mm and 1.73±0.18mm, and cochlear nerve density were 232.84±316.82 and 196.58±230.05 HU, respectively. The study found there was a significant difference in cochlea’s measurement between the two groups with a p-value < 0.05.="" this="" study="" had="" established="" baseline="" measurements="" for="" the="" cochlear="" for="" the="" healthy="" sudanese="" population.="" furthermore,="" it="" found="" that="" hrct="" of="" the="" temporal="" bone="" was="" the="" best="" for="" investigation="" of="" the="" cochlear="" and="" could="" provide="" a="" guide="" for="" the="" clinicians="" to="" manage="" congenital="" hearing="" loss.="" 0.05.="" this="" study="" had="" established="" baseline="" measurements="" for="" the="" cochlear="" for="" the="" healthy="" sudanese="" population.="" furthermore,="" it="" found="" that="" hrct="" of="" the="" temporal="" bone="" was="" the="" best="" for="" investigation="" of="" the="" cochlear="" and="" could="" provide="" a="" guide="" for="" the="" clinicians="" to="" manage="" congenital="" hearing="" />
