What is the most common age range for acute otitis (inflammation of the middle ear) media?

From the Guidelines

The most common age range for acute otitis media is in children 6-24 months of age. This is based on the evidence from the study published in Clinical Infectious Diseases 1, which states that the highest incidence of AOM is in children 6-24 months of age.

Key Factors Contributing to the High Incidence in this Age Group

• Anatomical factors, such as shorter and more horizontal Eustachian tubes, which impair proper drainage and ventilation of the middle ear
• Immunological factors, as the immune system is still developing, making children more vulnerable to respiratory infections that often precede ear infections
• Environmental factors, such as attendance in daycare settings, where children are exposed to more pathogens and have close contact with other children

Importance of Early Diagnosis and Treatment

It is crucial to diagnose and treat AOM promptly to prevent complications, such as hearing loss, which can have a significant impact on a child's speech, language, and cognitive development. The study highlights that patients with middle-ear effusion suffer from hearing loss of variable severity, with an average hearing loss of 25 decibels 1.

Decreasing Incidence with Age

The incidence of AOM declines with age, except for a limited reversal of the downward trend at the time of entry into day care or school, as noted in the study 1. However, it is essential to remain vigilant and monitor for signs of AOM in children of all ages, as it can still occur and have significant consequences if left untreated.

From the Research

Age Range for Acute Otitis Media

The most common age range for acute otitis media (inflammation of the middle ear) is:

• Between 6 to 24 months of age, as stated in the study 2
• Peak incidence between 6 and 15 months of age, as mentioned in the study 3
• By three years of age, 50% to 85% of children will have at least one episode of AOM, according to the study 4

Key Findings

Some key findings related to the age range for acute otitis media include:

• AOM is the most common diagnosis in childhood acute sick visits 4
• AOM is one of the most frequent infections affecting children, usually occurring between 6 to 24 months of age 2
• The rates of AOM have declined over time with better uptake of vaccines against Streptococcus pneumoniae, but it is still prevalent in the pediatric population 5

Treatment and Diagnosis

Treatment and diagnosis of AOM in children depend on various factors, including:

• Physical examination findings, as stated in the study 5
• Symptoms such as ear pain, fever, irritability, otorrhea, anorexia, and sometimes vomiting or lethargy 4
• Diagnosis is made based on a combination of acute onset of symptoms, signs of middle ear inflammation, and effusion 5
