Background: This prospective study compared the application of a 3D exoscope (VITOM 3D) with surgical microscopes (SM) in ear surgery.
Methods: 62 patients were included (exoscope group (E+) n = 31; SM group (E-) n = 31). Procedures included cochlea implantation (nE + = 10, nE- = 10), reconstructive middle ear surgery due to chronic otitis media with (COMwC; nE + = 11, nE- = 11) and without cholesteatoma (COMsC; nE + = 10, nE- = 10).
Objectives: The active middle ear implant, Vibrant Soundbridge (VSB), can be implanted with a variety of couplers. Hearing outcome after implantation has been investigated in both temporal bone (TB) experiments and patient studies, but the relationship between experimental and clinical data is still weak in the literature. Therefore, experimental data from TB experiments should be compared with patient data in a retrospective study, in which the floating mass transducer is used with couplers of the third generation.

- The causes of hearing loss are diverse, stemming from genetic factors, infections, environmental conditions, and various health disorders.
- The Vibrant Soundbridge (VSB) is a type of implantable hearing aid designed specifically for those with sensorineural hearing loss and relies on proper attachment to the incus for optimal performance.
- Mechanical modeling and finite-element models (FEM) play a crucial role in understanding how the ear functions and evaluating the VSB, allowing for detailed simulations that can improve surgical outcomes and device effectiveness.
Active middle ear implants or implantable hearing aids are used to treat sensorineural or combined hearing loss. Their coupling to the middle ear structures has a large impact on the success of rehabilitation. Practical issues such as the coupling site, influence of middle ear status, and forward and backward excitation of the inner ear are discussed in the context of biomechanics.

- In patients with chronic middle ear disease, the fully implantable active middle-ear implant (FI-AMEI) may be a viable treatment option, particularly after revision surgeries for ventilation and hearing issues.
- Twelve patients with severe mixed hearing loss underwent a retrospective case review following FI-AMEI implantation, with five having the implant placed in fat-obliterated cavities and seven after intact canal wall surgery.
- Results showed a significant improvement in monosyllable scores (40-85%) within three months, indicating that FI-AMEI implantation could be a noteworthy alternative for hearing rehabilitation, though further studies with larger samples are needed for confirmation.
