C Absent corneal reflex
D Trigeminal neuralgia

Ans. A B, C, D . Tinnitus, Deafness, Absent corneal reflex and d. Trigeminal neuralgia

The two most common CP angle tumors are:

Acoustic neuromas

Meningomas

M/C symptom = U/L Deafness

2nd M/C symptom Tinnitus

M/C nerve involved = Facial nerve :. absent corneal reflex is seen

M/C symptom = U/L Deafness (80%) followed by vertigo (75%) and tinnitus = 60%

In meningiomas : Unlike Acoustic neuroma - Trigeminal neuralgias, facial paresis, lower cranial nerve deficits and visual disturbances are more common.

Hence all the above features are seen in CP angle tumors.
