Surgery and Device Based Therapies[1]
A surgical candidate is the patients with conductive hearing loss due to mechanical problems, such as perforation of ear drum, ossicular disease, or a cholesteatoma in middle ear.
- Myringotomy and tube placement (middle ear effusions)
- Hearing aids ( There are different styles hearing aid depending upon their location behind the ear, in the ear, in the canal, completely in the canal. Devices worn in the canal are difficult to use.)
- Middle ear implantable devices
- Cochlear implants (Patients with a range of hearing who no longer benefit from hearing aids may benefit from cochlear implantation)
- Reconstructive middle ear surgery (including stapedectomy and tympanoplasty)
Cochlear implants
Patients who no longer benefit from hearing aids may benefit from cochlear implantation. Cochlear implantation technology and surgical techniques have advanced significantly since its approval for commercial use in 1985. [2]
Mechanism of Action
Cochlear implants send sound signals directly to the auditory nerve, bypassing cochlear hair cells. A receiver unit and an intracochlear electrode that is surgically implanted, typically under anesthesia. Once the device is activated, a speech processor is worn behind the ear.
Risks associated with surgery: [3]
- Facial nerve injury
- Dizziness
- Cerebrospinal fluid leak
- Infection
- Chorda tympani lesion causing loss of taste
