A patient has RIGHT facial drooping but CAN still close the eye on that side. There is rapid-growing swelling at the posterior ramus with nerve damage. What is the most likely CAUSE?
Show answer and explanation
Correct answer: A. Neoplasm (tumor)
Key finding: patient CAN close the eye (rules out Bell's palsy, which affects upper and lower facial muscles). Rapid growth + nerve damage + ramus location + painless = NEOPLASM compressing selective facial nerve branches. Source confirms: 'd. Neoplasm.'
- A. CORRECT. Neoplasm — selective facial nerve branch involvement + rapid painless growth + ramus location = tumor.
- B. Bell's palsy affects ENTIRE facial nerve — patients CANNOT close the eye. Here the eye CAN close → not Bell's palsy.
- C. Bacterial cellulitis = painful, warm, erythematous swelling; not rapid painless growth with nerve damage.
- D. Viral infection (Ramsay Hunt) = vesicular rash + ear pain — not rapid-growing ramus swelling.
