PurposeA transcanal endoscopic infracochlear surgical approach to the internal auditory canal in a human temporal bone model has been described. The proportion of patients with favorable anatomy for this novel surgical technique is unknown. Herein, we perform a quantitative analysis of the infracochlear corridor to the IAC based on computed tomography.Materials and methodsComputed tomography scans of adult temporal bones were measured to determine the accessibility of the IAC when using a transcanal, cochlear-sparing surgical corridor.ResultsThis approach to the IAC was feasible in 92% (35 of 38) specimens based on a minimum distance of 3mm between the basilar turn of the cochlear and the great vessels (jugular bulb and carotid artery).ConclusionsInfracochlear access to the IAC is feasible in the majority of adult temporal bones and has implications for future hearing preservation drug delivery approaches to the IAC.
