Removal of Cyanoacrylate Glue From the External Auditory Canal With Hydrogen Peroxide and Acetic Acid: A Case Report.

Ear canal foreign bodies are commonly encountered in the field of otolaryngology. This is especially common in the pediatric otolaryngology discipline. As a foreign body, cyanoacrylate glue (also called "super glue") can be difficult to remove and cause significant patient distress. Multiple solvents can be described as aiding in removing such foreign bodies. Here, a case is described in which hydrogen peroxide and acetic acid were used sequentially to remove cyanoacrylate glue from the external auditory canal. We describe a technique allowing en bloc removal of the cyanoacrylate glue. Thankfully, the patient's hearing returned to baseline post-operatively with minimal complications. Overall, cyanoacrylate glue can be a very difficult foreign body to remove from the ear canal. In this case, the sequential use of hydrogen peroxide and acetic acid to soak the glue was a safe and successful method to facilitate glue removal from the ear canal.
