Arm Intervention/treatment
Experimental: Tympanostomy Tube Placement Device: Tympanostomy tube placement (Acclarent iontophoresis device)
Placement of tympanostomy tube by the Acclarent tympanostomy tube delivery system following delivery of anesthetic with Acclarent iontophoresis device

Primary Outcome Measures :
  1. Number of Subjects With Procedural, Serious and Device-related Adverse Events. [ Time Frame: Procedure through 2 weeks post-procedure ]
    Adverse events which are procedural, serious, and device-related.

  2. Device Success [ Time Frame: Day 0 (day of procedure) ]
    Device Success is defined as the successful delivery of the tympanostomy tube (TT) across the tympanic membrane (TM) using the Tube Delivery System(TDS). Device Success will be evaluated on a per device basis.

Secondary Outcome Measures :
  1. Procedure Success [ Time Frame: Day 0 (day of procedure) ]
    Procedure Success is defined as the successful placement of any tympanostomy tube in all enrolled ears in a given subject. Procedure Success is determined on a per subject basis.

  2. Procedure Tolerability [ Time Frame: Day 0 (day of procedure) ]
    Procedure Tolerability is defined as the proportion of subjects reporting the procedure as tolerable, where tolerable is defined as a score of 0 through 3, using the Wong-Baker FACES pain scale.The Wong-Baker FACES pain scoring system is a scale of 0 to 5, where 0 means 'no hurt', 1 = 'hurts a little bit', 2 = 'hurts little more', 3 = 'hurts even more', 4 = 'hurts whole lot' and 5 = 'hurts worst'. Procedure Tolerability will be determined on a per patient basis, with the patient's score being the average of the scores for the left and right ear if both ears are successfully treated with the Tube Delivery System.

  3. Tube Retention [ Time Frame: 2 weeks post-procedure ]
    Tube retention is the presence of a tympanostomy tube placed successfully by the Tula TDS device across the tympanic membrane at the two-week follow-up visit.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Scheduled to undergo tympanostomy tube insertion
  • At least 6 months old
  • Behavioral capacity and cooperative temperament to undergo an awake procedure (based on physician judgement)
  • No history of sensitivity or reaction to anesthesia chosen for the procedure

Exclusion Criteria:
