C. Preparing Devices

Assess the tips of the Surgical Introducers to determine which one(s) will be used for the

procedure.

Prior to placing the Microstimulator, place the Microstimulator in physiologic saline inside a

sterile plastic basin away from a metal surface with the Microstimulator Lead completely

submerged. Complete an interrogation of the Microstimulator and perform an electrode

impedance test to ensure proper functionality as detailed in Section 11, Part H.

Next, bend the Microstimulator Bone Fixation Plate appropriately to the surgical anatomy by

holding the body with your fingers and using a tool. The Bone Fixation Plate bend should

reflect the following target Microstimulator placement:

• The Microstimulator body should lie flat against the posterior maxilla bone, medial to the

zygoma.

• The Microstimulator lead should be positioned within the superior medial

pterygopalatine fossa (PPF) using a lead trajectory that is inferior to superior within the

PPF. This position and trajectory should ensure that at least one electrode is in close

proximity to the SPG.

• The Microstimulator Bone Fixation Plate should be positioned sub-periosteally over the

anterior zygomatic process of the maxilla.

D. Make an Incision

Using standard oral surgical techniques make a 1.0-1.5cm incision located 3–5 mm superior to

the mucogingival junction above the maxillary first or second molar and carried through the

maxillary periosteum (Figure 8).

E. Dissect to Target Anatomy

Elevate the maxillary periosteum superiorly and laterally to accommodate the Microstimulator’s

Bone Fixation Plate and to expose the edge of the zygomaticomaxillary buttress (Figure 9 and

Figure 10). Limiting the amount of periosteal elevation may improve post-surgical side effects

from the implantation procedure.
