Surgical methods

The receiver stimulator should be placed properly to allow for the optimal use of which external components?

• The battery pack and charger

• The remote control and accessories

• The microphone, speech processor, and transmitting coil

• The microphone and transmitting coil

The goal of minimizing trauma to the inner ear is most critical for achieving which potential positive outcome? Select the most appropriate

• Lower risk of infection

• Easier device programming

• Preservation of residual hearing

All of the following are direct surgical aims EXCEPT?

• Performing a fast and efficient surgical procedure

• Ensuring the long-term stability of the implant despite patient growth

• Positioning the electrode array for maximal nerve stimulation

• Protecting the delicate cochlear structures during electrode insertion

Placing an incision too close to the receiver-stimulator can lead to what two potential complications?

• Infection and nerve damage

• Extrusion or pain

• Dizziness and tinnitus

• Device failure and hearing loss

The C-shaped incision preserved blood supply from which artery?

• Occipital artery

• Posterior auricular artery

• Maxillary artery

Why must the overhang of the round window niche often be removed?

• To prevent the electrode from kinking

• To properly visualize the round window membrane and achieve the correct insertion angle into the scala tympani

• To harvest bone dust for sealing the cochleostomy

• To create space for a larger electrode

During cochleostomy via the round window approach, the surgeon must be careful to open the membrane ___________ to avoid damaging basilar membrane structure located immediately behind the superior region.

• anterior-inferiorly

• posterior-inferiorly

• anterior-superiorly

• posterior-superiorly

What is the primary purpose of drilling a suprameatal hollow in the Veria technique?

• To straighten the ear canal

• To improve visualization of the round window

• To accommodate the excess electrode

• To secure the receiver-stimulator
