The third ear infection in six months. The fourth antibiotic since September. The sleepless night waiting for the doctor to open his office. For parents of children prone to recurrent ear infections, this scenario is all too familiar. Acute otitis media is one of the most frequent infections of childhood, and recurrence is a reality for around 15 to 20 % of children who have had their first (Canadian Paediatric Society, 2023).
Understanding why some children have recurring ear infections helps them to better navigate their options and ask the right questions of their doctor.
Why do some children suffer from recurring ear infections?
The middle ear is connected to the nasopharynx by the Eustachian tube, a narrow canal that drains into the throat. In young children, this tube is shorter, more horizontal and less rigid than in adults, making it easier for bacteria and viruses to migrate into the middle ear during upper respiratory tract infections. This is why ear infections are so common in the first two years of life, and in day-care settings where respiratory infections circulate abundantly.
Some children have an anatomical or immune predisposition to recurrent otitis. Nasal allergies, enlarged adenoids and exposure to cigarette smoke are recognized risk factors. Children who attend daycare, those who use pacifiers for prolonged periods and those who sleep with a bottle are also at greater risk.
Possible complications of recurrent ear infections
The most frequent complication of recurrent ear infections is serous otitis, the persistence of fluid in the middle ear between acute episodes. This fluid, even in the absence of active infection, reduces sound transmission and can lead to transient hearing loss. In young children during language acquisition, persistent hypoacusis can delay vocabulary and communication development.
In rarer cases, untreated or poorly treated otitis can be complicated by mastoiditis, perforation of the eardrum or, exceptionally, meningitis. These serious complications warrant prompt medical attention for each episode.
Treatment options
Antibiotic therapy is not systematic for all ear infections. Current recommendations from the Canadian Paediatric Society advocate an active observation approach for mild to moderate ear infections in children over six months of age, with the introduction of antibiotics if symptoms persist or worsen after 48 to 72 hours. This approach reduces exposure to antibiotics and limits the development of bacterial resistance.
For children with documented recurrent otitis, insertion of transtympanic ventilation tubes, or T-tubes, by an otolaryngologist is the main surgical option. These small tubes, placed in the eardrum under brief general anesthesia, allow ventilation of the middle ear and significantly reduce the frequency of ear infections. They fall out spontaneously after several months to a few years. For children with enlarged adenoids, their removal, combined with the tubes, can further reduce recurrences.
Frequently asked questions about recurrent ear infections
When do we talk about recurrent ear infections?
Recurrent ear infections occur when a child has three or more ear infections in six months, or four or more in one year. These criteria are used to assess the indication for ENT consultation and intervention.
Does breastfeeding protect against ear infections?
Yes, breastfeeding, particularly exclusive breastfeeding for the first six months, is associated with a reduced risk of ear infections. Antibodies present in breast milk and the more upright position of breastfeeding compared to bottle-feeding contribute to this protection.
Do ventilation tubes affect hearing?
No, on the contrary. They generally improve hearing by draining fluid from the middle ear. Children with tubes can swim normally in most cases, but should avoid deep-sea diving and use earplugs for certain aquatic activities as recommended by the surgeon.
When to consult a healthcare professional
If your child has had several ear infections in the space of a few months, if you notice signs of hearing loss or language delays, if the episodes are associated with severe pain or high fever, a medical consultation is needed to assess the situation and discuss options.
A specialized doctor or nurse practitioner can assess your child's ears, document the pattern of episodes and refer you to an ENT specialist if intervention is indicated. A face-to-face consultation at one of our Omicron Clinic in Quebec gives you quick access.
