PRESENTATIONS OF MIDDLE EAR DISEASE Elizabeth Rose Royal Victorian Eye and Ear Hospital Royal Children’s Hospital
A “look and learn” lecture • Middle-ear conditions • Management of otitis media • Differential diagnosis of ear pain • Clinical cases • An invitation! (Or Two!)
OTITIS MEDIAA SPECTRUM OF DISEASE • acute otitis media • chronic otitis media with effusion • atelectasis of the tympanic membrane • chronic adhesive otitis media • chronic suppurative otitis media • tubotympanic (“safe”) • atticoantral (“unsafe”) and may be acontinuumof disease
ACUTE OTITIS MEDIA(AOM) • the presence of a middle-ear effusion • signs and symptoms of infection • fever, irritability, pain, otorrhoea
Management of AOM • Pain relief Decongestants (oral/topical) and antihistamines • do not make the eustachian tube function better • do relieve the symptoms of a blocked nose
Antibiotic therapy • if severe symptoms - pain - perforation • ≤ 2years of age • immune deficiency • cochlear implant • follow-up not possible
Antibiotic therapy • Recommended treatment is: amoxicillin 50mg/kg/day in 3 doses • Can give up to 100mg/kg/day • Continue for 5 days • If no improvement in 2 days change to amoxicillin/clavulanate
Penicillin allergy • trimethoprim-sulfamethoxazole • clindamycin • ceftriaxone IM, but will often need continuing oral medication
Antibiotic therapy • older children who can be accurate about their symptoms should be treated symptomatically • if no improvement after 2 days consider treatment with antibiotics
CHRONIC OTITIS MEDIA WITH EFFUSION(COME) • the presence of a middle ear effusion • asymptomatic apart from some hearing loss
CHRONIC SUPPURATIVE OTITIS MEDIA(CSOM)“deafness and discharge” • persistent disease • insidious onset • severe destruction • irreversible sequelae
1. tubotympanic disease(“safe”) central perforation 2. atticoantral disease(“unsafe”) cholesteatoma the presence of keratinising squamous epithelium in the middle ear
MANAGEMENT OF CHRONICOTITIS MEDIA WITH EFFUSION(and also retraction/atelectasis of the tympanic membrane)
AKA • grommets • tubes • pressure equalisation tubes • middle ear ventilation tubes
COME Who should have middle ear ventilation tubes?
1. COME for 4 months at least, with hearing loss 2. COME in a child ‘at risk’ regardless of the hearing 3. COME and structural damage to the tympanic membrane
1. Hearing loss • median hearing loss is mild but there is a wide range • no data on the criteria for what is a significant hearing loss
50% of children with persistent OME have hearing thresholds at 20 dB
20% of children with persistent OME have hearing thresholds at >35 dB
2. An ‘at risk’ child has an increased risk of developmental difficulties due to: physical sensory cognitive behavioural factors not related to the OME
‘At risk’ • Suspected or diagnosed speech and language delay or disorder • Autism-spectrum disorder and other pervasive developmental disorders • Blindness or uncorrectable visual impairment
Management of the ‘at risk’ child may include: • speech and language therapy along with management of the OME • hearing aids for hearing loss independent of the OME
Children with persistent OME who: • are not ‘at risk’ • do not have significant hearing loss • donothave structural abnormalities of the eardrum or middle ear should be examined every three months
PAIN (Otalgia)
DIFFERENTIAL DIAGNOSIS OF EAR PAIN A.External auditory canal • trauma ( e.g. from cotton bud abuse) • auricular haematoma • foreign body • otitis externa • external auditory canal tumour
DIFFERENTIAL DIAGNOSIS OF EAR PAIN B. Middle ear • acute otitis media • bullous myringitis • chronic suppurative otitis media • middle ear tumour
DIFFERENTIAL DIAGNOSIS OF EAR PAIN C. Referred pain • oropharynx (IXth nerve) • tonsillitis/post-tonsillectomy • carcinoma, including posterior tongue • laryngopharynx(Xth nerve) • pyriform fossa • upper molar teeth, TMJ, parotid gland(Vc) • impacted wisdom teeth • changes to bite from new dentures • cervical spine(C2, C3) • pain is often worse at night
