Further study details as provided by Acclarent:

Primary Outcome Measures:
  • Device Success, defined as the creation of a myringotomy and placement of the Acclarent Tympanostomy Tube across the tympanic membrane [ Time Frame: Procedural ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Cross-Over, which is defined as conversion of the procedure from Tympanostomy Tube Delivery System to the standard of care (manual myringotomy and tube placement). [ Time Frame: Procedural ] [ Designated as safety issue: No ]
  • Presence of the Tympanostomy Tube across the tympanic membrane at two weeks post-procedure. [ Time Frame: two weeks post-procedure ] [ Designated as safety issue: No ]
  • Adverse Events, which is defined as the occurrence of periprocedural Tympanostomy Tube Delivery System -related adverse events (intraprocedure through two weeks post procedure). [ Time Frame: Procedural ] [ Designated as safety issue: Yes ]
