This is a non-randomized, multicenter, prospective, clinical study intended to evaluate the effectiveness of a method for iontophoretic delivery of a buffered lidocaine/epinephrine solution for provision of tympanic membrane anesthesia in patients who are indicated for local anesthetic procedures requiring penetration of the tympanic membrane, including, but not limited to, myringotomy, tympanocentesis with culture or tympanostomy with tube placement.

Primary Outcome Measures:
  • Evaluate the anesthetic effect of the Acclarent designed iontophoresis local anesthesia system. [ Time Frame: 12 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Evaluate patient tolerability of the bilateral iontophoresis procedure. [ Time Frame: 12 hours ] [ Designated as safety issue: No ]
  • Evaluate parent satisfaction with the in-office procedure. [ Time Frame: 12 hours ] [ Designated as safety issue: No ]
  • Evaluate any adverse effects associated with the iontophoresis system. [ Time Frame: 12 hours ] [ Designated as safety issue: Yes ]
