- The Chvostek sign is a clinical finding associated with hypocalcemia, or low levels of calcium in the blood. This clinical sign refers to a twitch of the facial muscles that occurs when gently tapping an individual's cheek, in front of the ear. The Chvostek sign aims to elicit an atypical reaction of the facial nerve, the nerve that innervates ...

- In the late 1800s, Dr. Chvostek noticed that mechanical stimulation of the facial nerve (as with the examiner's fingertip, for example) could lead to twitching of the ipsilateral facial muscles. [1] The long-accepted explanation is that this resulted from hypocalcemia, and this relationship became known as the Chvostek sign. [2] When corrected for albumin, a calcium …

- Schultze 2 observed that Chvostek's sign could also be easily evoked by percussion of an area between the corner of the mouth and the zygomatic arch. The responses to this mode of stimulation are now often called Chvostek signs II and III, according to the extensiveness of the response within the muscles supplied by the middle facial branch.

- The Chvostek's sign (also Weiss sign) is one of the signs of tetany seen in hypocalcemia. It refers to an abnormal reaction to the stimulation of the facial nerve. When the facial nerve is tapped at the angle of the jaw, the facial muscles on the same side of the face will contract momentarily (typically a twitch of the nose or lips) because of ...

- The facial phenomenon which is called the Chvostek sign consists of the rapid contraction of the facial muscle (or muscles) supplied by the seventh cranial nerve, elicited on tapping the nerve itself or its branches. Chvostek [i] described the increased irri- tability of the facial nerve.

- The Trousseau sign is another clinical sign that is suggestive of hypocalcemia. Chvostek sign can be defined as a visible spasm of the ipsilateral perioral muscles in response to mechanical stimulation of the facial nerve. It is commonly seen in postoperative tetany. This phenomenon was first observed by Franz Chvostek (1835-1884).
Chvostek’s Sign: Positive vs Negative Sign in Hypocalcemia
- https://www.registerednursern.com/chvosteks-sign/
- Chvostek’s sign is a specific type of facial muscle twitching that occurs when cranial nerve VII (the facial nerve) is manually stimulated by tapping the finger over the masseter muscle of the jaw. A positive sign demonstrates hyper-excitability of the facial nerve. This is not to be confused with Trousseau’s sign of latent tetany, which is ...

- Chvostek sign (also known as Chvostek-Weiss sign or Schultze sign 1) is the facial twitch obtained by tapping the distribution of the facial nerve in front of the tragus.It is caused by mechanical irritability of peripheral nerves. It is indicative of hypocalcemia and is the most reliable test for hypocalcemia.
