Jul 29, 2024 · The cochlea (plural: cochleae) is part of the inner ear osseous labyrinth found in the petrous temporal bone. It contains the cochlear duct, part of the membranous labyrinth which senses hearing.

A cochlear cleft is a narrow curved lucency extending from the cochlea towards the promontory. It is often visible in infants and children but can also be seen in adults. It can be mistaken for a fracture line or an otosclerotic focus.

Axial CT scan showing the posterior semicircular canal, the IAM, cochlea, and the malleus and incus. Axial CT scan showing the stapes suprastructure. The malleus handle and the long process of incus are also clearly seen.

Cochlear malformations ranging from complete labyrinthine aplasia, cochlear aplasia, to incomplete partition type I (IP-I) and incomplete partition type II (IP-II) (Fig. 15) are readily diagnosed on CT.

In this study, we present a fast, practicable and freely available method for estimating cochlear size and shape from clinical CT. The approach taken is to fit a template surface to the CT data, using either a statistical shape model or a locally affine deformation (LAD).

May 7, 2023 · Cochlear implants (CI) are surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. Unlike conventional hearing aids, the cochlear implant does not amplify sound but works by directly stimulating any functioning auditory nerves inside the cochlea with an electric field.

Nov 17, 2021 · The modiolus (plural: modioli) is part of the cochlea and is a conical-shaped structure that consists of spongy (porous) bone located in the center of the cochlea and contains the spiral ganglion. The spiral lamina projects from the modiolus.

Knowledge about cochlear duct length (CDL) may assist electrode choice in cochlear implantation (CI). However, no gold standard for clinical applicable estimation of CDL exists. The aim of this study is (1) to determine the most reliable ...

CT findings of enlarged cochlear aqueduct in an 18-month-old boy. A, Axial scan obtained through the temporal bone shows dilatation of the lateral orifice (small arrow) and otic segment (large arrow) of the cochlear aqueduct. Note the associated common cavity malformation (C) of …

Our aims were to explore the microarchitecture of human cochlea using micro-computed tomography (μCT), analyze electrode's placement inside cochlea after CI°, and compare pre-/post-implantation μCT scans with cone-beam CT (CBCT) scans of same TBs.
