Definition of Acute suppurative otitis media (OM):
Acute suppurative otitis media (OM) is an infection of the middle ear space that is characterized by the presence of pus or other fluid within the middle ear. It typically occurs as a complication of a bacterial or viral upper respiratory infection and is most commonly seen in children.

OVERVIEW
What is Acute suppurative otitis media (OM)?
ASOM stands for Acute Suppurative Otitis Media. It is an infection of the middle ear space characterized by the presence of pus or other fluid within the middle ear. ASOM usually develops as a complication of a bacterial or viral upper respiratory infection and is most commonly seen in children. Symptoms of ASOM include ear pain, fever, hearing loss, and discharge from the ear. Treatment may involve antibiotics to clear the infection, pain relief medication, and/or surgical drainage of the middle ear in more severe cases.
CAUSES AND RISK FACTORS
The primary cause of acute suppurative otitis media (ASOM) is bacterial or viral infections, which lead to inflammation and accumulation of fluid or pus in the middle ear. Here are some of the factors that increase the risk of developing ASOM:
- Age: ASOM is more common in children, particularly those aged 6 months to 3 years, due to the smaller size and shape of their Eustachian tubes, which makes it easier for bacteria to enter and cause an infection.
- Upper respiratory infections: Common colds, flu, and other respiratory infections can spread to the middle ear and cause ASOM.
- Eustachian tube dysfunction: Dysfunction of the Eustachian tube, which normally helps drain fluid from the middle ear, can cause fluid to accumulate and lead to an infection.
- Exposure to smoke: Exposure to cigarette smoke can increase the risk of ASOM.
- Allergies: Allergic reactions that cause swelling in the Eustachian tubes can increase the risk of ASOM.
- Family history: Children with a family history of ASOM are more likely to develop the condition.
- Cleft palate: Children with cleft palate are at higher risk of developing ASOM due to abnormal Eustachian tube function.
- Immune system deficiencies: People with weakened immune systems are more susceptible to infections, including ASOM.
SIGNS AND SYMPTOMS
The signs and symptoms of acute suppurative otitis media (ASOM) may vary depending on the severity of the infection, but some of the most common ones include:
- Ear pain: This is often the first and most common symptom of ASOM, which can be severe and can worsen when the person lies down.
- Fever: ASOM can cause a fever of 100.4 F (38 C) or higher.
- Difficulty hearing: Accumulated fluid or pus in the middle ear can cause a decrease in hearing or even hearing loss.
- Ear drainage: In some cases, fluid or pus may drain from the affected ear, which can be yellow, white, or green in color.
- Headache: ASOM can cause a headache, particularly in children.
- Irritability: Infants and young children with ASOM may become irritable or fussy due to pain and discomfort.
- Nausea and vomiting: ASOM can cause nausea and vomiting, particularly in children.
- Redness and swelling: The affected ear may appear red, swollen, and tender to the touch.
- Dizziness: In some cases, ASOM can cause vertigo or dizziness.
If you or someone you know is experiencing any of these symptoms, it is important to seek medical attention promptly to receive proper treatment.
DIAGNOSIS
A doctor will diagnose acute suppurative otitis media (ASOM) by performing a physical examination and asking about the symptoms. They will use an otoscope to examine the ear and check for signs of inflammation, redness, or discharge. The doctor may also perform a hearing test to determine the extent of hearing loss.
In some cases, further testing may be necessary to confirm the diagnosis or rule out other conditions. These tests may include:
- Tympanometry: A test that measures the movement of the eardrum in response to changes in air pressure.
- Audiometry: A test that measures hearing ability by presenting sounds at different frequencies and volumes.
- Culture of ear discharge: This test involves collecting a sample of ear discharge and sending it to a laboratory for analysis to determine the specific bacteria causing the infection.
- Imaging tests: Imaging tests such as a CT scan or MRI may be necessary if the doctor suspects complications such as a ruptured eardrum or the spread of infection to nearby structures.
Overall, a thorough evaluation by a healthcare professional is necessary to accurately diagnose ASOM and determine the most appropriate treatment.
MANAGEMENT AND TREATMENT
The management and treatment of acute suppurative otitis media (ASOM) depend on the severity of the infection and the age and overall health of the patient. Treatment options may include:
- Antibiotics: Antibiotics are typically prescribed to treat bacterial infections that cause ASOM. The type and duration of antibiotics depend on the severity of the infection, the age of the patient, and any underlying health conditions. It is important to complete the entire course of antibiotics as prescribed to ensure the infection is fully treated.
- Pain relief medication: Over-the-counter pain relief medications, such as acetaminophen or ibuprofen, may help relieve ear pain and reduce fever.
- Ear drops: Ear drops containing antibiotics and/or steroids may be prescribed to help reduce inflammation and treat the infection.
- Surgical intervention: In severe cases, or if the infection does not respond to antibiotics or other treatments, surgery may be necessary to drain the fluid from the middle ear.
- Observation: In some cases, particularly in older children and adults with mild symptoms, the doctor may recommend a wait-and-see approach to observe if the infection resolves on its own.
- Prevention: Preventive measures such as avoiding exposure to smoke, washing hands frequently, and keeping up-to-date with vaccinations (e.g., pneumococcal vaccine) can reduce the risk of developing ASOM.
It is important to follow the doctor's recommendations and complete the full course of treatment to ensure complete resolution of the infection and prevent complications such as hearing loss or the spread of infection to nearby structures.
COMPLICATIONS
Acute suppurative otitis media (ASOM) can lead to several complications if left untreated or if the infection does not respond to treatment. Some of the possible complications include:
- Ruptured eardrum: The buildup of fluid and pressure in the middle ear can cause the eardrum to rupture, leading to hearing loss, ear discharge, and increased risk of infection.
- Mastoiditis: Infection of the mastoid bone, located behind the ear, can occur when the infection spreads from the middle ear. Mastoiditis can cause severe pain, swelling, and fever and may require surgical intervention.
- Meningitis: In rare cases, the infection can spread to the brain and cause meningitis, a serious and potentially life-threatening condition.
- Facial nerve paralysis: In rare cases, ASOM can cause inflammation of the facial nerve, leading to paralysis of the face.
- Chronic otitis media: If the infection persists for a long time or recurs frequently, it can lead to chronic otitis media, a condition that can cause permanent hearing loss.
It is important to seek medical attention promptly if you or someone you know is experiencing symptoms of ASOM to receive proper treatment and prevent complications.
PREVENTION AND PROGNOSIS
Prevention:
There are several measures you can take to reduce the risk of developing acute suppurative otitis media (ASOM):
- Practice good hygiene: Wash your hands frequently, particularly before eating or touching your face.
- Avoid exposure to smoke: Smoke can irritate the lining of the ear and increase the risk of infection.
- Keep up-to-date with vaccinations: Vaccines such as the pneumococcal vaccine can help prevent bacterial infections that can cause ASOM.
- Breastfeeding: Breastfeeding can help boost the baby's immune system and reduce the risk of developing infections.
- Avoid sharing utensils or personal items: Sharing utensils or personal items with someone who has an ear infection can increase the risk of transmission.
Prognosis:
With proper treatment, most cases of ASOM resolve without complications. However, in some cases, the infection can lead to complications such as a ruptured eardrum or the spread of infection to nearby structures. It is important to seek medical attention promptly if you or someone you know is experiencing symptoms of ASOM to receive proper treatment and prevent complications.
