This young girl presented with swelling in the neck which moves on deglutition. She complaints of dyspnea and venous engorgement in face. She is examined with following test. The name of this sign is:
**Core Concept**
The patient's symptoms of swelling in the neck that moves with swallowing, dyspnea, and venous engorgement in the face suggest a condition affecting the airway, specifically the larynx or trachea. The clinical test used to diagnose this condition involves assessing the mobility of a specific structure.
**Why the Correct Answer is Right**
The correct answer is related to the diagnosis of a condition that affects the airway, specifically the larynx or trachea. The test is used to assess the mobility of the larynx. During swallowing, the larynx is elevated to prevent food from entering the airway. The inability to move the larynx during swallowing can indicate a condition that affects the airway, such as a mass or a tumor. This is a key concept in respiratory medicine, where the ability to move the larynx during swallowing is critical to prevent aspiration.
**Why Each Wrong Option is Incorrect**
**Option A:** This is not a relevant sign for the described symptoms.
**Option B:** This is not a specific test for the described condition.
**Option C:** This is a test for a different condition, not related to the described symptoms.
**Clinical Pearl / High-Yield Fact**
The ability to move the larynx during swallowing is known as the "laryngeal elevation reflex." This reflex is critical to prevent aspiration during swallowing. A condition that affects this reflex can lead to aspiration and other respiratory complications.
**Correct Answer: C.**
