BAHA - Direct Bone Conduction Hearing Implants, 2 Options

The BAHA osseointegrated hearing implant has been successfully used to treat over 35,000 patients worldwide and consists of:

  • Option 1: various lengths of percutaneous BAHA5 Connect fixture/abutments that are surgically implanted in the skull bone behind the ear.
  • Option 2: a BAHA5 Attract fixture/magnet implanted subcutaneously in the skull bone behind the ear (not implanted at The Ear Center at this time)

With Option 1, the BAHA5 Connect system, an external digital sound processor containing directional microphones and a battery supply is then "snap coupled" to a percutaneous abutment.

With Option 2, the BAHA5 Attract system, an external digital sound processor is is coupled to an external magnet that couples transcutaneously with an implanted magnet attached to the implanted titanium fixture.

Minimally Invasive "Punch" Technique:


The BAHA surgical procedure is performed at The Ear Center through a minimally invasive, 5 mm punch technique, behind the ear under general anesthesia as an outpatient. The procedure takes less than one hour. The fixture i s permitted to heal in the bone for 4 weeks before the various types of BAHA5 external sound processors are attached (loaded).

The BAHA5 implant requires minimal skin care, does not occlude the ear canal, and provides hearing to both inner ears by completely bypassing the outer ear, ear canal, and middle ear.

Sound

We receive sound in two ways, by air conduction via the ear canal, eardrum, and ossicles, and by bone conduction where sound is transmitted directly through the jaw and bones of the skull bypassing the outer ear and the middle ear.

Conditions

In most cases, hearing impaired patients will be fitted with air conduction devices. These are placed inside the ear canal or behind the ear. However, some hearing impaired patients are unable to benefit from this type of conventional hearing aid. They may have a congenital condition, such as never developing an ear canal (atresia) so there is no functional ear canal present in which to place a hearing aid. They may have chronic ear infection in the middle ear or the outer ear that is made worse when a hearing aid mold is placed in the ear canal causing occlusion. Such a situation applies to many patients who have undergone modified or radical mastoidectomy procedures.

Single Sided Deafness

Another hearing loss condition is called "Single Sided Deafness" (SSD) that may be due to previous surgery, trauma, ear disease, sudden hearing loss, Meniere's Disease, etc. which leaves the individual with no hearing in one ear.

Traditionally, patients with SSD were offered either traditional bone conduction devices which were large, cumbersome, and required the wearing of a steel spring headband or a CROS hearing aid system (contralateral routing of signal). CROS devices required wearing a microphone on the dead ear, connected by wired or wireless connection a second hearing aid in the opposite ear. Most patients reject both types of devices as they are very cumbersome.

Candidacy

The BAHA5 system is recommend for adults and children older than 5 years of age. Its specific indications include:

  • conductive hearing loss, in one or both ears, with average bone thresholds better than 45 dB for the BAHA5, 55 dB for the BAHA5 Power, and 65 dB for the BAHA5 SuperPower device
  • congenital absence of the ear canal(s) (congenital atresia)
  • single sided deafness in which one ear is completely without hearing and the other ear hears relatively normally

Two Different Implant Approaches Compared to Traditional Bone Conduction Hearing Aids

The BAHA5 hearing implant works through a different approach to bone conduction. Whereas traditional bone-conductors are transcutaneous and work by exerting pressure against the skull, the BAHA5 system works either percutaneously (BAHA5 Connect) or transcutaneously with an implanted fixture/magnet (BAHA5 Attract). A small titanium implant is implanted in the skull behind the ear where it osseointegrates with the living bone. With the BAHA5 Connect, a percutaneous abutment is attached the implant, and a sound processor is snap-coupled to the abutment. The sound processor can be worn or taken off at any time. The BAHA sound processor is comfortable and discreet. With the BAHA5 Attract, a subcutaneous fixture/magnet is implanted and the externally worn sound processor magnetically attracts transcutaneously to the subcutaneous fixture/magnet. Only the BAHA5 Connect system is being implanted at The Ear Center at this time.

 

Three Different BAHA5 Sound Processors to Chose From, Depending on Your Hearing Needs

  1. BAHA5 Sound Processor - the smallest processor: for hearing loss up to 45 dB
  2. BAHA5 Power - slightly larger than the BAHA5: for hearing loss up to 55 dB
  3. BAHA5 SuperPower - the first head-worn super power bone conduction processor: for hearing loss up to 65 dB

Control of Feedback

Feedback is annoying for all patients who wear hearing devices. With the BAHA system, feedback is either mechanical (400-1000 Hz range) or acoustic (1500-3000 Hz range). One way to reduce potential feedback is to reduce gain or apply a notch filter. These solutions lead to a loss of power (gain), audibility, and decreased hearing. The Intenso uses phase cancellation technology to automatically, and effectively, cancel the feedback with an out-of-phase sound signal of the matched frequency, amplitude, and phase.

Indications

Indications for the BAHA Intenso include conductive or mixed hearing losses for patients whose bone conduction thresholds are within the 0 - 45 dB range across the speech frequencies and for patients who have Single Sided Deafness (SSD).

Accessories

Intenso accessories that are available include:

  • an audio adapter for direct input from stereos, TV's, MP3's, and other Hi-Fi equipment,
  • a Phonak MicroLink Baha FM-receiver
  • a telecoil unit to access loop facilities in phones, homes, theaters, seminar halls, etc.

The BAHA Intenso Sound Processor is slightly larger than the BAHA Divino Sound Processor.

Located on inside surface, the surface closer to the head, are the the snap connector, tone and gain controls, a battery compartment, and an attachment point for an optional safety line. The Intenso weighs 14 grams, including a 675 battery.

 

BAHA DermaLock Implants with Abutments - Current Technology

Cochlear Americas is now manufacturing the BAHA DermaLock implants with abutments (model BIA400) and the BAHA DermaLock abutments (model BA400). The new abutments are made of titanium and are coated with a 80um thick coating of hydroxyapatite (Ca5(PO4)3(OH). The surface roughness (Ra) is approximately 7um. The implants are available in 3 mm and 4 mm models (B1300). Abutment length is determined according to scalp tissue thickness. The hydroxyapatite coating has been developed to improve tissue integration with the implant.
