What conditions can affect the external auditory canal (EAC)?

• A. Only genetic deformities
• B. Impacted cerumen, infections, and growths
• C. Only infections
• D. Hearing loss only

Answer: (B)

The external auditory canal (EAC) can be influenced by a variety of conditions, making the response that identifies impacted cerumen, infections, and growths as significant factors the most accurate. Impacted cerumen, or earwax buildup, is a common issue that can obstruct sound transmission and lead to temporary hearing loss or discomfort. Infections, such as otitis externa (commonly known as swimmer's ear), can cause pain, swelling, and discharge, further impacting auditory health. Additionally, growths, whether benign or malignant, can form within the canal, potentially causing blockage or other complications. This multifaceted approach recognizes the various ways the EAC can be affected, showcasing the importance of considering both physiological and pathological conditions in audiology. This perspective is crucial for hearing instrument specialists, as addressing these conditions can lead to improved patient care and sound management strategies.
