What is a common presentation in patients with otosclerosis?

• A. Unilateral tinnitus and vertigo
• B. Progressive conductive hearing loss
• C. Severe facial pain
• D. Sudden sensorineural hearing loss

Answer: (B)

Otosclerosis is a condition that primarily affects the bones of the middle ear, particularly the stapes, leading to impaired sound conduction. The hallmark of otosclerosis is progressive conductive hearing loss, which typically develops gradually as the condition progresses. This type of hearing loss occurs because the abnormal bone growth around the stapes prevents it from moving properly and transmitting sound waves effectively to the inner ear.

Patients might also experience difficulty hearing soft sounds, especially in quiet environments. As the condition advances, the hearing loss can become more pronounced, affecting communication and quality of life. By contrast, other options like unilateral tinnitus and vertigo, severe facial pain, and sudden sensorineural hearing loss are not typical presentations of otosclerosis. These could relate more closely to other conditions or causes affecting the auditory system or the cranial nerves. Thus, the progressive conductive hearing loss is a defining feature of this condition, making it the most relevant choice among the options provided.
