component• Cases of conductive hearing loss with a growing

deterioration of sensorineural hearing

Audiological guidelines:

• SNHL preferably not exceeding 70dB HL• Preserved speech discrimination scores

• MET and Carina cover a broad range of the hearing loss• Safe surgeries - no risk - fully reversible• Very stable implanting systems

• Carina: ü indicated for multiple hearing loss profilesü many options for middle ear stimulationü an invisible hearing system ü a unique alternative for

• severe mixed hearing loss• working in challenging conditions
