The purpose of this study is to evaluate the performance and safety of the Tympanostomy Tube Delivery System (TTDS) for chronic otitis media or recurrent acute otitis media.

Condition Intervention Phase
Otitis Media With Effusion Acute Otitis Media Device: tympanostomy tube Phase 2 Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Clinical Study of the Acclarent Tympanostomy Tube Delivery System for the Treatment of Patients Requiring Tympanostomy Tube Insertion for Otitis Media

Further study details as provided by Acclarent:

Primary Outcome Measures:
  • Safety of Tympanostomy Tube (TT) Delivery System [ Time Frame: 7 days ]
    Occurrence of pre-defined Safety Events of acoustic trauma, deployment of the TT into the middle ear, damage to middle ear structures, unintended tympanic membrane perforation requiring treatment, abrasion to the external acoustic meatus requiring significant treatment, and major bleeding requiring significant treatment.

  • Device Success [ Time Frame: 0 days ]
    Device Success is defined as the successful delivery of the tympanostomy tube across the tympanic membrane using the tympanostomy tube delivery system (TTDS).Device Success is evaluated on a per device basis.

Secondary Outcome Measures:
  • Proportion of Subjects With Procedure Success [ Time Frame: 0 days ]
    Procedure Success was defined as the successful placement of any tympanostomy tube in all enrolled ears in a given subject. Non-Acclarent tubes successfully placed manually following non-success of the TTDS were counted toward Procedure Success. Procedure Success was determined on a per subject basis: the rate was calculated by the number of subjects achieving Procedure Success out of the total number of enrolled subjects.

  • Tube Retention [ Time Frame: 7 days ]
    Presence of the tympanostomy tube across the tympanic membrane at the follow-up visit.
