Surgical Guide: SYNCHRONY PIN Cochlear Implant

SYNCHRONY PIN Cochlear Implant

Life is full of bumps & bruises: falls on the playground, fender-benders on the road, or accidents around the house. For a cochlear implant recipient, a bump to the head can often mean an impact against their implant.

That’s why secure implant fixation is essential for every cochlear implant recipient. However, secure fixation can be a challenge, especially when using minimally invasive surgical techniques.1

To provide secure fixation with a minimally invasive technique, we created our PIN cochlear implant housing. This design can provide much simpler, faster fixation than drilling a bony well & using implant sutures.1,2

Today, we’re going to go over the basic surgical technique for implanting SYNCHRONY PIN. Keep reading for a step-by-step animation that demonstrates the simple, straightforward processes for this reliable fixation technique.


SYNCHRONY PIN Cochlear Implant

First, let’s start by going over the implant design. SYNCHRONY PIN has two small titanium fixation pins built into the receiver housing. These durable pins are designed to lock into corresponding holes drilled in the temporal bone.

Together with a tight subperiosteal pocket, this direct mechanical connection to the temporal bone provides superior fixation and long-term stability.

  • Small incision behind the pinna (approx. 3 cm)
  •  Minimal drilling to flatten stimulator housing area (<1 mm)
  • No implant fixation sutures

Step-by-Step Instructions

Now, let’s look at the surgical steps for implanting a SYNCHRONY PIN. This step-by-step animation includes:

  • Selecting implant position with processor template
  • Utilizing a minimal incision technique
  • Creating a tight periosteal pocket
  • Using fingertips to determine outline of periosteal pocket
  • Flattening the implant bed if necessary
  • Drilling a proper electrode lead channel
  • Using the PIN Drill Guide SI (Template)
  • Drilling the PIN holes
  • Placing the implant
  • Securing the electrode lead
