How-to: Sphenoid Access & Dilation

Suggested Tools

Procedure Steps

PREPARE PATH WITH PATHASSIST SPHENOID SEEKER/FREER

1. Use a 30⁰ scope to visualize treatment area

  • Leverage anatomical landmarks to help with direct visualization
  • If needed, use the PathAssist Sphenoid Seeker/Freer to lateralize middle turbinate and locate sphenoid ostium

ACCESS AND DILATE WITH XPRESS

2. Use the bending tool to adjust the tip of XprESS to the sphenoid (‘S’) configuration

3. Palpate the XprESS LoProfile device into desired sinus space

4. Advance balloon and inflate

REMOVE AND VISUALIZE

5. Deflate balloon and remove device

6. When possible, use scope to visualize dilation

Sphenoid Procedure Pearls

  • Do not advance the XprESS device further than 1cm into the sphenoid sinus
  • Enter the sphenoid ostium from the inferior and medial aspect to stay away from the internal carotid artery and optic nerve.
  • The sphenoid ostium is level with the posterior aspect of the maxillary ostium
  • Leave a slight angulation to the distal end of the XprESS tip to rotate the device into the sphenoid ostium in the event that access is not straight


IFUs

XprESS

XprESS Indications for Use: To access and treat the frontal recesses, sphenoid sinus ostia, and maxillary sinus ostia/ethmoid infundibula in adults using a trans-nasal approach. The bony sinus outflow tracts are remodeled by balloon displacement of adjacent bone and paranasal sinus structures. Please see the Instructions for Use below for a complete listing of contraindications, warnings, precautions and adverse events.

LED Light Fiber

LED Light Fiber Indications for Use: To locate, illuminate within, and transilluminate across nasal and sinus structures in patients aged 18 and over. Please see Instructions For Use for a complete listing of contraindications, warnings, precautions, and adverse events.
