There are many treatment options available for cerumen impaction including observation, ceruminolytic agents, irrigation or manual removal other than irrigation and also combination of ceruminolytic agents with either irrigation or manual removal.
But so far there are no studies comparing the effectiveness of water used as ear drops in a similar fashion to commercially available ear drops or if water can actually be an alternative for commercially available ceruminolytic ear drops or is there any additional adverse effects of using water in this manner.
Water has been shown to have a ceruminolytic action whereas 2% Para-dichlorobenzene is a wax softening agent and so the disintegration of wax after using water may be more effective.
In light of the hazards of mechanical removal, it is often preferable to use a ceruminolytic agent to soften or dissolve an impaction or to loosen it from the tympanic membrane.
Singer et al evaluated the ceruminolytic effect of docusate sodium and triethanolamine polypeptide.
Ceruminolytic effects of docusate sodium: A randomized, controlled trial.
BACKGROUND Options for removing cerumen include the use of a ceruminolytic, a curette, irrigation, or a combination.
RESULTS Immediately after ceruminolytic instillation there was no difference between the 2 treatments.
This study was not designed to evaluate the efficacy of ceruminolytics on a chronic basis.
A ceruminolytic should disrupt the structural integrity of the keratin sheets and thereby soften, loosen, liquefy, and/or dissolve cerumen and perhaps even float it out.
its keratin content), and the temperature of the ceruminolytic.
