Outcome Measures

Primary Outcomes (1)

  • Identifying contraindications for cochlear implant

    Identifying contraindications for cochlear implant including * cochlear nerve aplasia (evidenced by MRI) * cochlear and/or labyrinthine aplasia * absence of the internal auditory canal and of the petrous apex bone * absence or fusion of the ossicles

    Day 0

Study Arms (1)

"cochlear implantation" group

"cochlear implantation" group: patients undergoing cochlear implantation between December 2019 and December 2021in the ENT department of Assiut university hospital.

Diagnostic Test: Computed Tomography and Magnetic resonance imaging

Interventions

Preoperative imaging for patients undergoing cochlear implants

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study will be performed in Assiut University Hospital, Department of Radiology during the period from May 2019 to May 2021, and will include 50 patients from different age groups and both sex who will be clinically diagnosed as having severe to profound SNHL and fulfill the criteria for the cochlear implant.

You may qualify if:

  • Patients fulfilled criteria for cochlear implant including audiological criteria (as bilateral profound hearing loss not benefiting from hearing aid) and phoniatric criteria as IQ (using Stanford Binet intelligence scale) more than 80 with no medical, surgical, or radiological contraindication for surgery
  • Family motivation and commitment for audiologic and phoniatric rehabilitation and follow up
  • Confirmation of the presence of cochlear nerve using preimplant MRI.

You may not qualify if:

  • Patient who did not fulfill the criteria for indicating cochlear implant surgery
  • Patients with no records of preoperative investigations
  • Patients with major dysplasia or aplasia of the cochlea as a common cavity.
