Hearing Evaluation-PE Tube Scarring

I observed a client who, overall, had all normal results as a conclusion for an annual hearing evaluation. During case history, the client revealed that he/she was taking medications for cholesterol, allergies, and acid reflux. No significant changes were noticed with hearing.
The clinician first performed otoscopy. When looking in the right ear, a large amount of scar tissue was noticed. The client revealed that PE tubes were used at a young age in both ears. The results were similiar in the left ear. PE tubes are usually placed when problems with fluid buildup occur in the middle ear space (Martin & Clark, 2006). Tympanometry was normal for both ears.
Puretone results were as follows: Right ear - 250Hz=0dB, 500Hz=5dB, 1kHz=5dB, 2kHz=0dB, 3kHz=10dB, 4kHz=5dB, and 8kHz=15dB / Left ear - 250Hz=0dB, 500Hz=10dB, 1kHz=5dB, 2kHz=5dB, 3kHz=10dB, 4kHz=15dB, 6kHz=10dB, and 8kHz=15dB. The clinician explained the normal results to the client.
The following website contains information dealing with otoscopy and otoscopic results. It also has little quizzes and such! Great resource: www.aap.org/otitismedia/www/vc/ear/rvw/rvw17.cfm
