The helicotrema (from Greek: ἕλιξ [helix] meaning coil and τρη̂μα [trēma] meaning hole), also known as Scarpa hiatus, 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 is a part of the cochlear labyrinth where the scala tympani and the scala vestibuli meet.[1][2] It is the main component of the cochlear apex.[2]
Function
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]
