In the same Ramsay Hunt syndrome case, which part of the tongue has affected taste sensation due to the involved nerve?
Show answer and explanation
Correct answer: A. Anterior 2/3 of the tongue (ipsilateral)
- A. CORRECT. The chorda tympani nerve (a branch of the facial nerve, CN VII) carries taste sensation from the anterior 2/3 of the tongue. In Ramsay Hunt syndrome affecting CN VII, taste from the IPSILATERAL anterior 2/3 of the tongue is impaired.
- B. The posterior 1/3 of the tongue is supplied for taste by the glossopharyngeal nerve (CN IX) via the lingual branch — not CN VII.
- C. Taste fibers from CN VII supply the ipsilateral (same side) anterior tongue — not the contralateral side.
- D. Bilateral tongue taste involvement would require bilateral cranial nerve lesions — Ramsay Hunt is unilateral.
