All are true about Gardenigo’s syndrome except: [AIPGMEE – 2005]
- Associated with conductive hearing loss
- Caused by an abscess in petrous apex
- Leads to involvement of the cranial nerve 5 and 6
- Characterised by retro-orbital pain
Characteristic triad of Gradinego’s syndrome is: otorrhoea, unilateral deep retro orbital pain (in areas innervated by 1st and 2nd branch of Trigeminal nerve), diplopia due to ipsilateral abducens nerve paralysis (lateral rectus muscle palsy ) caused by apical petrositis
This is also seen in extra-dural abscess and meningitis of the petrous apex.
Extra points to note: the most common lesion of the petrous apex is Cholesterol granuloma followed by meningioma and congenital cholesteatoma
