Which physical examination sign is classic for hypocalcemia after thyroid surgery?

Explanation:
Low calcium after thyroid surgery causes increased neuromuscular irritability, so the most recognizable bedside sign is Chvostek's sign: tapping the facial nerve just in front of the ear triggers twitching of the facial muscles. This reflex is a classic indicator of hypocalcemia in the post-thyroidectomy setting. Trousseau's sign, a carpopedal spasm with a blood pressure cuff, also reflects hypocalcemia but the facial tapping sign is the quintessential exam finding here. Signs like Bragard or Homan are unrelated to calcium status.
