Ear infections are part of almost every family's experience with young children. They cause significant discomfort, disturb sleep, and are among the most common reasons for GP consultations and antibiotic prescriptions in children. The management of ear infections has evolved considerably with better understanding of which cases need antibiotics and which will resolve on their own.
Healthbooq (healthbooq.com/apps/healthbooq-kids) covers common childhood illnesses and when to seek help.
What Otitis Media Is
Acute otitis media (AOM) – the most common type of ear infection – is infection and inflammation of the middle ear, the space behind the eardrum. It is most often precipitated by a viral upper respiratory infection that causes Eustachian tube dysfunction: the tube connecting the middle ear to the back of the throat becomes swollen and blocked, trapping fluid in the middle ear space where bacteria (most commonly Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis) can then proliferate.
Young children are more susceptible than older children and adults for anatomical reasons: their Eustachian tubes are shorter, more horizontal, and floppier, making them more prone to dysfunction. The peak incidence of AOM is in children aged 6-24 months.
The classic symptoms are earache (often worse at night; young children may pull at their ear or be unusually distressed without being able to specify the pain), fever, and disturbance following a cold. However, ear pulling alone is not a reliable indicator of ear infection – many babies pull at their ears simply because they have discovered them.
Antibiotics: The Evidence for Watchful Waiting
One of the most significant shifts in clinical guidance over the past two decades has been the move away from routine antibiotic prescribing for AOM. Research including a large systematic review by Tamar Venekamp and colleagues at the Julius Center in Utrecht, published in the Cochrane Database, found that in children over 2 years with mild to moderate AOM, most cases resolved without antibiotics, and antibiotics modestly shortened duration of pain but significantly increased adverse effects (diarrhoea, rash, vomiting).
NICE guidance CG69 (Respiratory Tract Infections) supports a "watchful waiting" approach for most children with AOM: manage pain and fever with paracetamol and ibuprofen for 2-3 days, and prescribe antibiotics only if symptoms are not improving or are worsening. Antibiotics are recommended immediately for: children under 2 years; children with severe symptoms (high fever, significant distress, discharge from the ear indicating perforation); and children who are not improving after 48-72 hours of watchful waiting.
Amoxicillin is the antibiotic of choice for AOM in most cases; alternatives are used where allergy is present.
Glue Ear (Otitis Media with Effusion)
Glue ear (otitis media with effusion, OME) is the accumulation of thick, mucoid fluid in the middle ear without acute infection. It is very common in young children: around 80% of children will have had at least one episode by age 4. It causes a conductive hearing loss (sound is not conducted effectively through the fluid-filled middle ear), which is typically mild to moderate (around 25-30 dB, comparable to having your fingers in your ears).
This hearing loss is the main concern with glue ear because it can affect speech and language development, particularly if it is bilateral and persistent during critical periods of language acquisition. Children with persistent glue ear may appear to "mishear," not respond when called from another room, or have speech that seems unclear.
Most glue ear resolves spontaneously – typically within 3 months for a single episode. NICE guideline NG91 recommends a period of watchful waiting (typically 3 months) before investigation of surgical intervention. Grommet insertion (small ventilation tubes inserted in the eardrum under general anaesthetic) is recommended when glue ear is persistent, bilateral, and associated with significant hearing loss affecting development or quality of life. Research by Mark Haggard at the MRC Institute of Hearing Research on the TARGET trial documented the outcomes of grommets versus watchful waiting in the UK context.
Hearing aids are an alternative to grommets for some children; this choice is made in consultation with audiology and ENT services.
Key Takeaways
Ear infections (otitis media) are among the most common bacterial and viral infections in young children. Most acute otitis media resolves without antibiotics: in children over 2 years with mild to moderate illness, watchful waiting for 48-72 hours is appropriate and reduces antibiotic exposure without worsening outcomes. Antibiotics are recommended for children under 2, children with severe illness, or those whose symptoms are not improving after 48-72 hours. Glue ear (otitis media with effusion) is a common cause of mild-moderate hearing loss and temporary language delay in young children; most cases resolve without surgery. Grommet insertion is recommended when glue ear is persistent and affecting hearing significantly.
