Middle Ear

• Otitis media

– Acute

– Chronic otitis media +/- cholesteatoma

– Otitis media with effusion

– Complications

• Tympanic membrane perforation

• Hearing loss

– Conductive

www.manchester-

ent.co.uk

Acute Otitis Media

• Definition– Inflammation of the middle ear cleft

• Demographics– Mostly children (age 3-7)

• Aetiology– Viral (majority)

– Bacterial (1y or 2y) - Strep. Pneumoniae, H. influenzae, Bramhamellacatarrhalis)

• Risk Factors– Poor sanitation/ hygiene and parental smoking

– Exposure to other children

– Eustachian Tube Dysfunction

– ? allergy

www.manchester-

Natural History

Infection via ET tube (Fever)

Mucosal oedema

Hyperaemia of tympanic membrane & purulent middle effusion

Bulging tympanic membrane (Pain)

Pressure necrosis of tympanic membrane resulting in perforation

Mucopurulent discharge

Acute Otitis Media

www.manchester-

ent.co.uk

Acute Otitis Media

• Treatment

– Expectant

– Paracetamol/NSAIDS

– Oral amoxycillin

– +/- myringotomy

• Complications

– Acute• Mastoiditis

• Facial palsy

• Labyrinthitis

• Meningitis

• Intracranial abscess

• Lateral sinus thrombosis

- Long term

•Tympanosclerosis

• Tympanic membrane perforation

•Ossicular damage

www.manchester-

Acute Mastoiditis

• History of acute otitis

media

• Infection spreads to

mastoid

• Post-auricular abscess

• Treatment

– Grommet

– Cortical mastoidectomy

Perforation• Causes

– Trauma

– Otitis media

– Iatrogenic eg. Grommets

• Symptoms

– None

– Recurrent otorrhoea

– Hearing loss

www.manchester-

ent.co.uk Tympanic Membrane

Perforation

• Treatment

– None

– Myringoplasty

– +/- ossiculoplasty

Graft is placed under perforation to allow epithelium to regrow

Myringoplasty

www.manchester-

Ossiculoplasty

www.manchester-

Chronic OtitisMedia

• Without cholesteatoma

– Tympanic membrane perforation

– Chronic middle ear infection

– May resolve with topical or oral

antibiotics

– If no resolution – myringoplasty

+/- cortical mastoidectomy

•Otorrohoea for more than 3 months

• May occur with or without cholesteatoma

www.manchester-

ent.co.uk

Chronic Otitis Media

• With cholesteatoma

• Eustacian tube dysfunction results in tympanic membrane retraction

(attic)

• Accumulation of keratin in retraction pocket

• Gradual enlargement and adjacent bony destruction

• Complications as for AOM above

Chronic Otitis Media with

Cholesteatoma

• Treatment is surgical

• Aims of surgery

− Remove all disease

− Dry ear

− +/- Restore hearing

• Types of operation

– Modified radical mastoidectomy

– Canal wall up mastoidectomy

www.manchester-
