What is it indicated for?

Sepragel ENT packing/stent is indicated for use in patients undergoing nasal/sinus,

middle ear and external ear canal surgery as a space-occupying dressing and/or stent

intended to prevent adhesions in the nasal cavity, separate mucosal surfaces, help control

minimal bleeding following surgery or trauma, and act as an adjunct to aid in the natural

healing process. The device is indicated for use in the middle ear following canalplasty,

myringoplasty, tympanoplasty, stapes and mastoid surgery. The device is indicated

following nasal/sinus surgery or trauma to prevent lateralization of the middle turbinate

during the post operative period.

Indications for use as stated in the FDA summary.
