Q

How to tell the difference between Vestibular neuritis and labyrinthitis

A

Presentation - Acute vertigo (AN/L) + hearing loss (L only)

This is because vestibular neuritis only affects the vestibular nerve whereas labyrinthitis is a disorder affecting the inner ear as a whole or CN 8 as a whole.

Surgical removal
Atticotomy – if small and limited to the attic

Radical Mastoidectomy – if more advanced and extends into mastoid

Complications can arise if the sac erodes into:
Ossicles – causing conductive deafness

Facial Nerve – causing facial palsy

Labyrinth – causing vertigo

Tegmen (roof of middle ear) – causing intracranial sepsis

Cochlea – causing sensorineural deafness

Sigmoid Sinus – causing it to thrombosis

Intracranial

Idiopathic
Bells Palsy
