1. OTOlogics develops middle ear implants (MEI), including the fully implantable Carina hearing system and semi-implantable MET system, which have been implanted in over 800 patients worldwide. 2. The Carina is a fully implantable hearing system consisting of a microphone, battery, signal processor, and transducer. It received CE marks for sensorineural and conductive/mixed hearing loss. 3. The Carina is indicated for patients with ear canal issues, those who work in challenging environments, and conductive or mixed hearing losses. It provides an invisible and reversible option to address various hearing loss profiles.

8. Sensorineural Hearing Loss
Patients with a normal middle ear anatomy
And with a mobile ossicular chain
Transducer simply placed in contact with the incus

9. Audiological Guidelines
Hearing loss, preferably not exceeding 70dB HL
Pure tone air and bone conductions must be within this range
Preserved speech discrimination
Experience in using hearing aids is preferable

10. Indications
For patients with
Ear canal complications (size, allergies, reactions )
Hearing aid users with dermatitis, psoriasis,
chronic external otitis
And those working in challenging environments
(water, dust)
Removes the stigma of wearing an external device

11. Conductive Hearing Loss
Flexible placement options of the transducer
Delivers clear and powerful acoustic signals to the cochlea
Stapes Round Window Oval Window

12. Indications
Congenital Aural Atresia
Healed Cholesteatoma
Revised Ossiculoplasties
Traumatic Injury
Counter indications:
- Persistent middle ear infections
- Tympanic perforation

13. Mixed Hearing Loss
Audiological guidelines:
SNHL preferably not exceeding 70dB HL
Preserved speech discrimination scores
Indications:
Otosclerosis
Healed cholesteatoma with a sensorineural component
Stabilized chronic otitis media with a sensorineural
component
Cases of conductive hearing loss with a growing
deterioration of sensorineural hearing

14. Conclusions
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 profiles
ü many options for middle ear stimulation
ü an invisible hearing system
ü a unique alternative for
severe mixed hearing loss
working in challenging conditions
