A 42-year-old man goes to his primary care physician for evaluation of hearing loss. The patient has had worsening hearing loss out of the right ear for the past six to nine months. He has also been experiencing intermittent ringing in the affected ear. Family history is notable for similar symptoms in his father, who developed progressive hearing loss starting at the age of 35. On physical exam, temperature is 37.5°C (99.5°F), blood pressure is 147/88 mmHg, and pulse is 73/min. Otoscopy of the patient's right tympanic membrane demonstrates the finding below.

Summary
Conductive hearing loss occurs when there is a problem with how sound waves are conducted from the outer ear to the inner ear. This type of hearing loss can be due to several factors, including ear infection, ear wax build-up, and damage to the eardrum or middle ear bones. Symptoms of conductive hearing loss can include difficulty hearing sounds clearly, especially in noisy environments, and muffled sounds.
