What is the Baha ® system? The BAHA system has been a well recognized hearing treatment for conductive and mixed hearing losses since 1977 (Collaborative effort between Nobelpharma, University of Gothenborg, and Chalmer’s University) The BAHA system is an implanted direct bone conduction hearing rehabilitation system (osseointegration) Sound is conducted through the skull bone bypassing the middle ear and stimulates the cochlea The BAHA system produces natural sound through direct bone conduction The BAHA system is composed of three parts: a titanium implant, an external abutment and a sound processor
FDA Clearances (1996 – 2002) 1996 –the BAHA system was cleared to treat mixed and conductive hearing loss. 1999 –the BAHA system was cleared for pediatric use in children age five and older. 2001 –the BAHA system was cleared for bilateral fittings. 2002 –the BAHA system was cleared for use in patients with unilateral sensorineural hearing loss also known as Single Sided Deafness (SSD).
Types of Hearing Loss the Baha ® System Can Help Mixed and Conductive hearing loss – unilateral or bilateral fitting –Due to examples such as: Chronic otitis media Congenital atresia/Microtia Cholesteatoma Middle ear dysfunction/disease
Direct bone conduction Summary: Works independently of ear canal and middle ear Direct transmission gives clear sound Preoperative testing possible High wearing comfort Safe and simple surgery
How does the Baha ® system work for Mixed and Conductive Hearing Loss?
Advantages of the Baha ® System in comparison to other alternatives Mixed and Conductive Hearing Loss No occlusion of the ear canal No feedback problems Sound bypasses the middle ear Predictable results Low risk for the patient Reversible surgery More comfortable Better sound quality Aesthetic appearance Over air conduction devices Over reconstructive surgery Over bone conduction devices
Baha ® Compact 1.Volume control, on/off 2.Electrical input 3.Battery compartment 4.Battery door 5.Microphone 6.Abutment snap 7.Attachment for safety line 8.Gain control 9.Tone control 10.Serial number
Personal Hygiene Simply clean skin around the abutment with a soft cleaning brush and gentle soap. This type of cleaning should take place at minimum 1 time daily after the area is healed from surgery.
