True about vocal nodule is/are -a) Also known as screamer’s nodeb) Occur at junction of ant. 1/3rd & post. 2/3rd of vocal cordsc) Most common presentation is aphoniad) Microlaryngoscopic surgery is not useful

**Core Concept**
Vocal nodules are benign growths on the vocal cords, typically occurring due to vocal abuse or misuse, leading to repetitive strain on the vocal cord tissues.

**Why the Correct Answer is Right**
Vocal nodules are indeed also known as "screamer's nodes" due to their association with loud or prolonged voice use. They most commonly occur at the junction of the anterior one-third and posterior two-thirds of the vocal cords, where the vocal cords have the most tension and vibration. The most common presentation of vocal nodules is indeed a hoarse or rough voice, but not necessarily aphonia, which is a complete loss of voice. Microlaryngoscopic surgery is often used to treat vocal nodules by removing the affected tissue and relieving tension on the vocal cords.

**Why Each Wrong Option is Incorrect**
**Option A:** While vocal nodules are sometimes referred to as "screamer's nodes," this term is not universally accepted and not as commonly used in medical literature as other terms.
**Option B:** Vocal nodules can occur at other locations on the vocal cords, but the junction of the anterior one-third and posterior two-thirds is the most common site.
**Option C:** Aphonia is not the most common presentation of vocal nodules; a hoarse or rough voice is more typical.
**Option D:** Microlaryngoscopic surgery is actually a useful treatment for vocal nodules, allowing for precise removal of affected tissue and relief of tension on the vocal cords.

**Clinical Pearl / High-Yield Fact**
When evaluating a patient with a hoarse or rough voice, it's essential to take a thorough history, including questions about vocal use and abuse, to identify potential causes of vocal nodules.

**Correct Answer:** a) Also known as screamer's node
