Medical treatment of choice in otosclerosis is:
**Core Concept**
Otosclerosis is a type of bone dyscrasia characterized by abnormal bone remodeling in the middle ear, leading to fixation of the stapes bone and conductive hearing loss. The medical treatment of choice aims to reduce bone remodeling and prevent further progression of the disease.
**Why the Correct Answer is Right**
The medical treatment of choice for otosclerosis is sodium fluoride (NaF) due to its ability to inhibit bone resorption and promote bone formation. Sodium fluoride works by reducing the activity of osteoclasts, the bone-resorbing cells, and promoting the activity of osteoblasts, the bone-forming cells. This leads to a decrease in bone remodeling and a reduction in the progression of otosclerosis.
**Why Each Wrong Option is Incorrect**
**Option A:** Steroids are not effective in treating otosclerosis as they do not specifically target the abnormal bone remodeling process.
**Option B:** Antibiotics are not indicated in the treatment of otosclerosis as it is a non-infectious condition.
**Option C:** Corticosteroids may be used in some cases of otosclerosis to reduce inflammation, but they are not the primary treatment of choice.
**Clinical Pearl / High-Yield Fact**
Sodium fluoride is most effective when started early in the course of the disease, as it can help prevent further progression of otosclerosis and reduce the need for surgical intervention.
**Correct Answer: C. Sodium fluoride.**
