Treatment
• Swab for sensitivities

Malignant OtitisExterna
• Osteomylitis of temporal bone
• Immunocompromised patients eg. Diabetes
• Usually pseudomonas
• Extremely painful
• May be associated with cranial nerve palsy
• Have a high index of suspicion
• Treat aggressively with IV antibiotics for at least 6 weeks

Treatment
• Aural toilet
• Topical antifungal agents eg. Canestan
www.manchester-

hair follicle causing
abscess formation

– Antiviralseg. Acyclovir
– Protect the eye
www.manchester-

Perichondritis
• Inflammation of perichondrium
• Aetiology:– Ear piercing

Hyperostosis
• Exostosis
– Multiple bony swellings in
deep canal
– Cold water
– Asymptomatic
– No treatmentunless large
• Osteoma
– Single benign bony
tumour outer bony
meatus
– No treatment unless
large

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-
ent.co.uk
Acute Mastoiditis
• History of acute otitis
media
• Infection spreads to
mastoid
• Post-auricular abscess
• Treatment
– Grommet
– Cortical mastoidectomy

www.manchester-
ent.co.uk Tympanic Membrane
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-
ent.co.uk
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-

Conductive Hearing Loss
• External ear– Wax
– Foreign bodies
