REFERRAL & SAFETY-NETTING (NO DRUG THERAPY)
Acute Otitis Media - StatPearls (NCBI Bookshelf NBK470332) - https://www.ncbi.nlm.nih.gov/books/NBK470332/
Counting the episodes is what turns repeated earache into an ENT referral. A single episode is treated on the acute-otitis-media entry; what belongs here is the threshold for grommets, the fact that long-term antibiotics are no longer the answer, and the modifiable risks worth naming to the family in the meantime.
- THE COUNT THAT TRIGGERS THE REFERRAL - by the AAP guidelines, a child who has had 3 episodes of acute otitis media within 6 months, or 4 or more within 12 months, should be considered for myringotomy and grommet insertion (tympanostomy).
- DO NOT PUT THE CHILD ON MONTHS OF ANTIBIOTICS INSTEAD - prophylactic antibiotics are NO LONGER advised for a child with recurrent acute otitis media; assess for grommets instead.
- AND THE EAR HAS TO BE WET ON THE DAY THE ENT SURGEON LOOKS - a grommet must NOT be inserted in a child with recurrent acute otitis media who has no middle ear effusion in either ear when they are assessed for it. An ear that is dry at the appointment can lose the child the operation, so time the referral to the pattern of episodes.
- WHY THE TUBE HELPS - repeated infections needing antibiotics are, clinically, evidence that the Eustachian tube is not working. A grommet ventilates the middle ear space, brings hearing back to normal, and heads off delay in speech. And a child with a grommet in place who catches another infection can be treated with antibiotic ear drops instead of another course by mouth.
- COUNT PROPERLY, BECAUSE THE NUMBER PREDICTS THE COURSE - a child who has had fewer than 3 episodes is about 3 times likelier to get better on a single course of antibiotic.
- RECHECK AT 48 TO 72 HOURS DURING AN EPISODE - a paediatric infection that has not answered the first antibiotic inside 48 to 72 hours is reassessed, with a view to changing the treatment. And where antibiotics are held back in favour of watchful waiting, agree a fallback plan for starting them.
- THE MODIFIABLE RISKS WORTH NAMING TO THE FAMILY - keeping up with the pneumococcal and influenza vaccines cuts down the upper respiratory infections that so often come before an episode. Carers should also keep the child away from tobacco smoke, second-hand and third-hand alike, which irritates the airway and raises the risk of infection. And breastfeeding, where it is possible, goes with less otitis media, because protective immunoglobulins pass to the child.
- THE RISKS THAT CANNOT BE CHANGED, BUT EXPLAIN THE PATTERN - no breastfeeding, or not for long. Exposures in the environment - passive smoking, and being in daycare. A lower socioeconomic position. Recurrent acute otitis media in the family, in a parent or a sibling. And an abnormality of the skull or the palate that stops the Eustachian tube working - a cleft palate, or a tensor veli palatini that does not function.
- AND ONE RISK IS AGE, WHICH THE CHILD GROWS OUT OF - the peak falls at 6 to 12 months of age, and the rate drops away after 5 years, as the angle of the Eustachian tube changes.
- FLUID BETWEEN EPISODES IS A DIFFERENT PROBLEM WITH THE SAME TREATMENT - a persistent effusion shows on otoscopy as thick amber fluid behind a retracted drum. Both conditions reduce the drum's mobility on tympanometry or pneumatic otoscopy and both cost hearing, which is exactly why one gets mistaken for the other and managed wrongly.
- STEROIDS AND ANTIHISTAMINES ARE NOT THE ANSWER TO EITHER - neither a systemic steroid nor an antihistamine has been shown to help meaningfully.
- CHECK THE HEARING AND THE SPEECH, NOT JUST THE DRUM - a referral for speech and language may be needed where delay persists, and particularly after grommets have gone in. Repeated infections in the first years cost a child hearing at the age they are learning to talk.
- WHEN TO SEND THE CHILD BACK SOONER - fever that will not settle, ear pain getting worse, or any change in hearing or in behaviour, all warrant review. Add to that a swelling or redness behind the ear, which is mastoiditis until proven otherwise.
