Accumulation of ear wax in the external ear canal is a common pathology. The presence of ear wax not only interferes with the clinician's view of the tympanic membrane, but may also result in hearing loss and vertigo, and may predispose to ear infections.

Removal of ear wax is facilitated using a variety of cerumenolytics, or ear wax solvents. The current study is designed to evaluate the safety and the cerumenolytic effects of the Earol product, when dosed into the auditory canal prior to the dewaxing and ear cleaning procedure. This study is designed to be conducted in the primary care setting as a prospective clinical trial.

A detailed literature review has been conducted to provide a background summary of relevant information on the disease/pathology, other available treatment options and the pre-clinical testing and clinical research that has been conducted to date on the intended population or related populations and/or the device.

The aim for conducting this clinical investigation is to perform a PMCF to evaluate the safety and performance of Earol. Although there are alternative methods for ear wax removal, Earol represents a simple method based on natural ingredients (olive oil) which aids the removal of ear wax as well as prevents appearance of clinical symptoms in the ear canal (E.g. reducing itching and irritation).
