Understanding Middle Ear Infection: A Common Illness Accompanying Colds in Both Children and Adults

Explaining the causes of "middle ear infection" from colds to ear infection, along with how to recognize symptoms in children and adults, and treatment methods to prevent dangerous complications involving the brain.

Watch carefully! If there is ear pain, discharge or pus, or if a child frequently touches their ear and cries inconsolably, these may be signs of "middle ear infection," a condition often accompanying colds. Left untreated, it can lead to severe complications such as brain infection.

Getting to know "middle ear infection," the silent threat behind the eardrum.

Middle ear infection is an infection in the middle ear located behind the eardrum. Its main cause usually begins with respiratory illnesses such as colds, tonsillitis, or adenoid inflammation. These conditions cause swelling of the respiratory lining, disrupting the ear pressure equalization tube’s function, leading to fluid or pus buildup inside.

Check the symptoms: Which indicate middle ear infection?

Symptoms often vary by age group as follows.

  • In young children: Since they cannot express themselves, parents should observe if the child frequently touches their ear, cries persistently when the ear is touched, and often has a fever.
  • In older children: They may report ear pain or a sensation of reduced hearing.
  • In adults: They typically experience clear ear pain and may have discharge or pus coming from the ear.
  • Note: Most symptoms usually occur in only one ear.

Worrisome complications if not treated promptly.

Although it seems like a common illness, if left chronic it can cause serious harm, such as:

  • Inflammation spreading to the mastoid bone behind the ear, resulting in an abscess.
  • Facial muscle weakness due to nerve involvement.
  • Brain infection (rare but highly risky).

Treatment approaches and prevention.

Diagnosis mainly comes from a physical examination by a doctor, often revealing a red, swollen eardrum or pus accumulation. Treatment methods include:

  • Treating the cause: If caused by a cold, symptoms of ear infection typically improve as the cold resolves.
  • Medication: Doctors may prescribe an appropriate dose of antibiotics.
  • Eardrum puncture: If medication fails, doctors may puncture the eardrum to drain pus and culture it for targeted treatment.

The best prevention is avoiding chronic colds, especially in children at daycare who are more susceptible to infections. If abnormal ear symptoms begin, see a doctor promptly.
