To overcome the most common problem faced of cerumen impaction, various methods exist to remove the debris and give the patient the immediate relief of hearing restoration. These methods are, Aural syringing , if the wax is clinically diagnosed to be of wet- type; suction is also used in these cases; manual removal using a Jobson’s probe has been proven effective too. In cases where the wax is visualised to be extremely dry with scaly lesions , the patient is advised to follow medication in the form of drops to soften the wax in order for easy painless removal. In this study, the hearing efficiency of the patient is measured before and after the removal of wax and correlated with each other. As an additional factor, the ear canal volume is also measured using impedance audiometry to determine any correlation with the amount of hearing loss. Patients fulfilling the inclusion criteria were be subjected to a PTA ( Pure tone audiometry) test in which the intensity of hearing was measured in decibels in both ears and plotted in the audiogram. The PTA threshold was determined at 250Hz, 500Hz, 1kHz, 2kHz, 4kHz and 8kHz by air conduction. Also bone conduction measurements were obtained at 500Hz, 1kHz, 2kHz and 4kHz. Following this, the patient’s ear was cleaned by using various techniques like suctioning, aural syringing, or using a Jobson’s probe. Once the ear canal was cleaned and confirmed by an otoscopic examination, the impedance audiometry was performed to measure the volume of the ear canal.After the removal of the wax a repeat PTA was done and plotted. The pre and post wax removal PTAs were compared and contrasted for differences in hearing loss. The data was analysed using the two-tail factor and was found to be significant. P value was found to be ; P<0.000000256 Impacted wax caused a significant degree of conductive hearing loss and improvement in hearing of patients following wax removal was present.
