Abstract

This research aims to characterize the geometry of the human cochlear spiral in vivo by measuring curvature and length. Magnetic resonance imaging (MRI) was used to visualise the human inner ear in vivo. The inner ear was imaged in 12 ears in 7 subjects recruited. Visualisation of the cochlear spiral was enhanced by T2 weighting and further processing of the raw images. The spirals were divided into 3 segments: the basal turn segment, the middle turn segment and the apex turn segment. The length and curvature of each segment were measured. The measured lengths of cochlear spiral are consistent with data in the literature derived from anatomical dissections. Overall, the apex turn segment of the cochlear had the greatest degree of curvature. A detailed description of the cochlear spiral is provided, using measurements of curvature and length. This data will provide a valuable reference in the development of cochlear implantation procedures.
