Patient Tolerance

Physicians Can Achieve High Patient Comfort When Utilizing Entellus Devices

Five studies reported pain scores for office based balloon dilation procedures. Four studies utilized Entellus devices; one study was sponsored by Acclarent, Inc. and utilized Relieva Solo Pro. All five studies utilized a 0 (no pain) to 10 (severe pain) discomfort scale.

For the Entellus studies, patients overall mean procedure pain levels were low—2.8.

Clinical Study n Average Pain Score
(0=No Pain; 10=Severe Pain)
XprESS Multi-Sinus 81 2.8
XprESS Maxillary Only 21 1.8*
RELIEF (In-office FinESS) 69 3.2
BREATHE I (In-office FinESS) 19 2.7
ORIOS2 (Acclarent in-office) 198 4.5

*(A subset of patients who were administered oral sedative and narcotic pain medication prior to the procedure reported an average pain score of 1.1)
