Chvostek sign – type I
How to elicit Chvostek-I sign
It is obtained by striking with a finger or a hammer a point that is approximately 2 cm in front of the lobe of the ear and about 1 cm below the zygomatic process.
Response
Response occurs in the form of ipsilateral contraction of some or all of the muscles innervated by the facial nerve.
Effect
The effect is the lateral deviation of the labial and nasal fold toward the stimulated side.
Chvostek sign – type II
Hitting a point between the middle third and upper third of the line joining the angle of the mouth to the zygomatic process gives rise to only a contraction of the muscles of the mouth and nose
