Otologic iontophoresis: a no-papoose technique

Area of Science:

• Otolaryngology
• Anesthesiology
• Medical Devices

Background:

• Myringotomy and pressure equalization tube insertion are common pediatric otologic procedures.
• Effective tympanic membrane anesthesia is crucial for patient comfort and procedural success.
• Current anesthesia methods may involve sedation or general anesthesia, posing risks.

Purpose of the Study:

• To evaluate a novel iontophoresis system and solution for tympanic membrane anesthesia.
• To assess the safety and clinical effectiveness of this new approach in an office setting.
• To determine the tolerability and pain experienced by patients undergoing otologic procedures.

Main Methods:

• A consecutive series trial involving 50 patients (86 ears) undergoing myringotomy.
• Utilized a US Food and Drug Administration-cleared iontophoresis system with a novel solution.
• Assessed pain using the Wong-Baker FACES Pain Rating Scale.

Main Results:

• Iontophoresis achieved successful anesthesia in 90.7% of ears.
• Average pain scores were low: 1.07 post-iontophoresis and 1.19 post-procedure.
• The overall otologic procedure was successful in 89.7% of treated ears.

Conclusions:

• The Acclarent iontophoresis system and novel solution are safe and effective for tympanic membrane anesthesia.
• This method allows otologic procedures in children as young as 12 months without sedation or general anesthesia.
• It offers a promising alternative for office-based pediatric ear procedures.
