The helicotrema (from
Greek: ἕλιξ [helix] meaning coil and τρη̂μα [trēma] meaning hole) is the part of the
cochlear labyrinth where the
scala tympani and the
scala vestibuli meet. It is the main component of the
cochlear apex. The
hair cells near this area best detect low frequency sounds.
The helicotrema connects the
scala tympani and the
scala vestibuli.[1][2] This allows fluid to move between the two.[1][2] It slightly impedes the travel of sound.[3] The
hair cells near this area best detect low frequency sounds.[1][4]
