If you do have sudden sensorineural hearing loss, treatment with steroids within the first 2 weeks of the symptoms provides the best chance that some of the hearing may return. The gold standard treatment for sudden deafness, if caught within two weeks of the onset of the symptoms, is high-dose steroids, taken by mouth.
Evidence now suggests that injection of medication into the middle ear, using a relatively painless and quick procedure in the clinic, is also effective in treating sudden sensorineural hearing loss without the side effects that can be seen when taking high-dose steroids by mouth. This study will compare high dose oral steroids with intratympanic, or middle-ear injections of a special formulation of steroid medication for the treatment of sudden sensorineural hearing loss. This Sudden Sensorineural Hearing Loss Multicenter Treatment Trial is the first prospective, randomized clinical trial to compare these two different treatment options. If you have any questions about Sudden Sensorineural Hearing Loss and treatment, please feel free to call Dr. The BAHA is a unique implantable device that helps people with conductive or mixed hearing loss. Figure 1  BAHA device consists of an implantable titanium post (left) and the hearing processor. Single-sided deafness – Patients may lose hearing on one side completely for various reasons.
Chronic ear infections – Some patients with chronic ear infections cannot wear a standard hearing aid since it may worsen the infection.
Congenital ear malformation – In some patients with congenital ear canal and middle ear malformations (congenital aural atresia), the hearing function cannot be restored by reconstructive surgery. Patients with hearing loss undergo a full ear, nose and throat evaluation in addition to testing such as an audiogram and imaging such as MRI. The Nucleus Hybrid System is a groundbreaking advancement that will change the way hearing loss is treated in the United States, expanding the scope of implantable hearing technology to a whole new indication. Our licensed and highly trained audiology staff will fit you with the most suitable hearing aid for your specific requirements. Middle ear implants are available to hearing-impaired patients who are dissatisfied with conventional hearing aids. If you have severe to profound sensorineural (cochlea: inner ear or hearing nerve) hearing loss, a cochlear implant device may be your solution to restored hearing. Acoustic tumors are tumors of the balance and hearing nerves, which are situated between the inner ear and the brain. CT shows soft tissue located medially to the ossicles and external displacement of the ossicles. External auditory canal cholesteatoma occurs when squamous tissue invades a localized area of periosteitis in the canal wall; its etiology and pathophysiology are unknown. Patients present with progressive conductive (fenestral type) or mixed (fenestral and cochlear type) hearing loss with normal findings on otoscopic examination.
Fenestral otosclerosis spreads from the oval window anterior margin?(fissula ante fenestram) to the all margin of oval and round windows.
Continued active disease spreads to the otic capsule (both fenestral and cochlear present).
Cochlear (or retrofenestral) otosclerosis is much less common but always associated with fenestral otosclerosis. CT shows bilateral “halo” of radiolucency surrounding the cochlea (arrows); also note the bilateral lytic lesions anterior to the oval window (broken arrows).
Incudomalleolar joint separation is most frequently observed in trauma cases and often associated with incudostapedial joint separation [1]. Developmental disorders that involve the ossicles and originate in the first and second branchial arches cause various ossicular anomalies.

Bilateral conductive deafness is an indication for surgical reconstruction (tympanoplasty). Fibrous dysplasia is a bone disorder in which dysplastic fibro-osseus tissue replaces normal bone. Stenosis of the external auditory canal causes infection that leads to cholesteatoma and hearing loss. MRI should be performed in all cases of sudden sensorineural hearing loss with uncertain cause [4]. Vestibular schwannoma is a benign tumor that arises when Schwann cells wrap the vestibular branches of CN8 in the cerebellopontine angle–internal auditory canal. Conductive or mixed hearing loss easily occurs when a tumor progresses into a temporal bone (inside the tympanic cavity) from the geniculate ganglion of the facial nerve.
Improvement of hearing loss is difficult because of damage to the inner ear or cochlear nerve. Labyrinthitis ossificans (LO) is the pathologic formation of new bone within the lumen of the otic capsule and associated with profound deafness and loss of vestibular function. LO is the final result of suppurative labyrinthitis regardless of the origin of the infection [5]. Approximately 20% of patients with congenital sensorineural hearing loss have radiographic abnormalities of the inner ear [11].
Sennarogu and Saatcu [12] have proposed a classification system for inner ear malformations based on radiological features. 2 clicks for more privacy: On the first click the button will be activated and you can then share the poster with a second click.

A typical patient loses his or her hearing in one ear over a period of one to several days, associated with a feeling of fullness in the ear, and often tinnitus, or ringing of the involved ear. Occasionally, the patient may report an upper respiratory infection (cold symptoms) prior to the onset of the hearing loss. The symptoms of decreased hearing and fullness of the ear are often diagnosed as a middle ear infection (otitis media) and so the referral to an audiologist or otolaryngologist (ENT specialist) is made too late. The diagnosis can only be made by specialized hearing testing in a sound-proof chamber by an audiologist.
There is a titanium fixture that is implanted directly into the skull that provides sound by bone conduction through the bone to the inner ear. Since the BAHA is implanted behind the ear and does not require use of the ear canal, it is an ideal device for use in these cases. Based on the medical evaluation, the treatment options for the hearing loss will be presented to you. The patient provides local wound care at home with application of antibiotic ointment to the site.

The Baha 5 Sound Processor is designed to help you enjoy listening to clearer, crisp sound and hear what people are saying in noisy environments.
This device (the med-el soundbridge) provides wonderful acoustic results in selected patients. Pure-tone thresholds, speech discrimination scores, acoustic reflex testing, and distortion product otoacoustic emission testing, the parts of a complete audiometric evaluation, are performed to confirm the diagnosis of a sudden sensorineural hearing loss. The sound is transmitted to the good ear on the other side directly through the bone without the need for wires or ear molds.

Those who are possible candidates for the BAHA can try out the BAHA test device which simulates the sound of the BAHA.
After a 3 month healing period, the hearing processor can be placed onto the titanium fixture for use.
During the first surgery, the titanium implant is placed and left completely under the skin to heal for 6 months. Maw has extensive training and experience in modern surgical techniques for their removal, ensuring minimal side effects and preserving optimal hearing.
8: Axial (a) and coronal (b) CT images of attic cholesteatoma (Stage 4) show soft tissue, which erodes the scutum and ossicles, in the Prussak’s space. 9: Axial sequential CT images of advanced attic cholesteatoma (Stage 4) show destruction of the semicircular canals and cochlea. 10: Axial (a) and coronal (b) CT images of tensa cholesteatoma show soft tissue, which erodes the incus, located medially to the ossicles. 11: (a) Axial CT image of the external auditory canal cholesteatoma shows soft tissue that erodes the external auditory canal, (b) opposite side (normal). 13: Axial (a) and coronal (b) CT images of tympanosclerosis show destructive ossicles and calcification in the attic. 14: Axial (a) and coronal (b) CT images show hematoma in the tympanic cavity and malleoincudal disarticulations.
17: Axial CT image of fibrous dysplasia (pagetoid type) shows stenosis of the external auditory canal by expansile “ground-glass” density that invades the sphenoid and petrous bones. 19: MRI T2-weighted image (a) and T1WI with contrast medium (b) of acoustic nerve schwannoma show well enhanced small nodular lesion in the left internal auditory canal. 21: Axial CT of labyrinthitis ossificans (b, d) and normal opposed side (a, c) show severe ossification of the cochlea, lateral semicircular canal, and vestibule. 24: MRI of T2WI (a–d) and volume-rendered images (e, f) show bilateral small common cavity (arrows) with narrow internal auditory canal (broken arrows) and hypoplastic semicircular canals (arrowheads). This comprehensive testing by an audiologist will ensure that the loss is nerve-related, and not due to fluid, infection, or a perforation, or hole in the ear drum.
The sound transmission for the BAHA is superior to that of a standard external bone conduction device, which must transmit sound through the skin and then into the bone. This device can help patients hear sounds coming from the deaf side without having to turn their heads.
The surgery consists of preparing the implantation skin site behind the ear, placement of the titanium implant, and placement of the dressing.
During the second surgery, the opening is made in the skin to allow the implant to be fitted with the hearing processor.
MRI scan of the brain, with gadolinium contrast, is also performed to exclude the presence of a cerebellopontine angle tumor, such as a vestibular schwannoma (acoustic neuroma).
Bone CT shows expansile mass lesion in right mastoid air cells extruding to the external auditory canal and an enlarged stylomastoid foramen. Jennifer Maw and her clinical team can address the full continuum of issues people encounter as they experience hearing loss or balance issues.
We combine expert medical and surgical care with state-of–the-art diagnostic evaluations and the most sophisticated hearing technology available.
