Facial Nerve Reanimation
A patient presents with facial nerve palsy following head trauma with fracture of the mastoid, best intervention here is:
| A |
Immediate decompression |
|
| B |
Wait and watch |
|
| C |
Facial sling |
|
| D |
Steroids |

Immediate onset paralysis due to fracture of mastoid (temporal bone) requires surgery (decompression, re-anastomosis or cable nerve graft).
Facial nerve is injured during parotid surgery. Best management would be:
| A |
Immediate repair |
|
| B |
Repair after 1 week |
|
| C |
Repair after waiting for partial recovery of nerve |
|
| D |
Do nothing, sent to higher centre |

Ans is ‘a’ i.e. Immediate repair
During mastoidectomy, when the facial nerve is injured, it is immediately explored. Injury to greater than 50% of the neural diameter of the facial nerve is addressed either with primary reanastomosis or reconstructed with the use of a nerve graft. Complete recovery of nerve function is uncommon in these cases.
Treatment of choice for CSOM with vertigo and facial nerve palsy is:
| A |
Antibiotics and labyrinthine sedative |
|
| B |
Myringoplasty |
|
| C |
Immediate mastoid exploration |
|
| D |
Labyrinthectomy |

Crocodile tears (gustatory lacrimation) There is unilateral lacrimation with mastication
- It is due to faulty regeneration of parasympathetic fibres which normally travel through chorda tympani but are misdirected towards greater superficial petrosal nerve and instead of going to salivary glands reach the lacrimal glands. This results in unilateral lacrimation with mastication
- Treatment – Sectioning the greater superficial petrosal nerve or tympanic neurectomy
- Frey’s syndrome (gustatory sweating) -There is sweating and flushing of skin over the parotid area during mastication.
Treatment of choice for mastoid fracture with facial nerve palsy is:
| A |
Nerve decompression |

| B |
High dose of steroid |

| C |
Sling operation |

| D |
Repair the fracture and wait and watch |
