Complications of otitis media
An infection can "'spread'" from the middle ear in several ways:
- by innate preformed paths;
- obtained by preformed paths;
- usuri in the bone;
- in osteothrombophlebitis.
In general, complications can be divided into:
Otological complications[edit | edit source]
Coalescent mastoiditis[edit | edit source]
For more information see Mastoiditis.
Petrositida[edit | edit source]
- This is inflammation of the glomeruli of the pyramid' and the formation of an abscessed deposit. Nowadays, this complication occurs only rarely.
- Clinically, we describe the so-called Gradenig syndrome, which includes fever, otorrhea, retrobulbar pain and diplopia.
- 'CT is mainly used in diagnostics.
- Treatment consists of the administration of antibiotics', in case of failure, surgical intervention can be performed (mastoidectomy, petrosectomy).
Paresis of the facial nerve[edit | edit source]
- In an acute infection, the nervus facialis is damaged by toxins'.
- In a chronic infection, the nervus facialis is compressed by a cholesteatoma'.
- In both cases it is a peripheral facial nerve paresis.
Labyrinthitis[edit | edit source]
We distinguish 3 forms of labyrinthitis':
- Perilabyrinthitis: In perilabyrinthitis, the cholesteatoma damages the bony capsule of the labyrinth and creates a labyrinthine fistula, which can be visualized by HRCT. The inner ear is not infected. The dominant symptom is vertigo.
- Serous labyrinthitis: As a result of the penetration of microorganisms or their toxins into the inner ear, a reversible inflammation occurs. Clinical symptoms include tinnitus, hypacusia (perceptual defect).
- Suppurative labyrinthitis': It is caused by the penetration of virulent microorganisms into the inner ear. The clinical picture' is severe - severe vertigo, tinnitus, nausea, vomitus, nystagmus, balance disorders. The great danger lies in the possibility of the infection spreading to the brain and cerebellum - the condition needs to be dealt with immediately (ATB, labyrinthectomy). The inevitable consequence of the disease is deafness.
Residues post otitis media[edit | edit source]
- Atrophy, atelectasis of the tympanic membrane, calcareous incrustations, perforation.
Intracranial complications[edit | edit source]
Intracranial complications include:
- 'thrombophlebitis of the ace-shaped raft
- usually a complication of mastoiditis, first a perisinusoidal abscess develops, then a mural thrombus, which becomes infected and spreads retrogradely and anterogradely,
- leads to bacteremia and the formation of secondary abscesses in the lungs, endocardium and brain,
- treatment is surgical - mastoidectomy and removal of the float;
- epidural or brain abscess,
- subdural empyema.
