Secretory (serous) otitis media can develop from acute otitis media that has not completely cleared or from a blocked eustachian tube The Eustachian Tube: Keeping Air Pressure Equal Middle ear infection is infection of the space immediately behind the eardrum.

Allergies and enlarged adenoids are common causes of eustachian tube blockage. Tumors are rare causes of blockage. Secretory otitis media can occur at any age but is particularly common among children (see Secretory Otitis Media in Children Secretory Otitis Media in Children Secretory otitis media is fluid that accumulates behind the eardrum and remains there after an acute middle ear infection or blockage of the eustachian tube. A previous ear infection is the... read more ) and may persist for weeks to months.
Normally, pressure in the middle ear is equalized 3 or 4 times a minute as the eustachian tube opens during swallowing. If the eustachian tube is blocked, pressure in the middle ear tends to decrease as oxygen is absorbed into the bloodstream from the middle ear. As the pressure decreases, fluid accumulates in the middle ear, reducing the eardrum’s ability to move.
Symptoms of Secretory Otitis Media
Usually, although not always, the fluid in the middle ear contains some bacteria, but symptoms of an active infection (such as redness, pain, and pus) are rare. People usually notice a fullness in the affected ear and may hear a popping or crackling sound when they swallow. Some hearing loss commonly develops.

Doctors examine the nasal passages and upper throat in adults and adolescents to check for tumors.
Treatment of Secretory Otitis Media
Decongestants for older children and adults
Maneuvers to increase pressure in the ear
Sometimes drainage tubes in the ear
Most people with secretory otitis media get better without treatment. Decongestants, such as phenylephrine and pseudoephedrine, can be taken by older children and adults according to the doctor's recommendations to reduce nasal congestion but do not help the secretory otitis media. Decongestants should be avoided in younger children, particularly those less than 2 years. People with congestion caused by allergies may be given antihistamines by mouth and/or a corticosteroid nasal spray. Antibiotics are not helpful. Low pressure in the middle ear can be temporarily increased by forcing air past the blockage in the eustachian tube. To do this, the person breathes out with the mouth closed and the nostrils pinched shut (called the Valsalva maneuver). Or the doctor can use a special syringe (middle ear inflator) to blow air into one of the person’s nostrils while blocking the other nostril as the person swallows. This technique (called politzerization) forces the air into the eustachian tube and middle ear.
If symptoms become chronic (lasting more than 1 to 3 months), a doctor may perform a myringotomy, in which an opening is made through the eardrum to allow fluid to drain from the middle ear. A tiny drainage tube (tympanostomy tube—see figure Myringotomy Myringotomy: Treating Secretory Otitis Media Secretory otitis media is an accumulation of fluid in the middle ear.

Myringotomy: Treating Secretory Otitis Media
During a myringotomy, doctors make a small opening in the eardrum to allow fluid to drain from the middle ear. Then they place a tiny, hollow plastic or metal tube (tympanostomy tube, or ventilating tube) in the eardrum through the opening. These tubes balance the pressure in the environment with that in the middle ear. Doctors recommend ventilating tubes for some children who have had recurring ear infections or recurring or persistent collections of fluid in their middle ears (chronic secretory otitis media).
Placement of ventilating tubes is a common surgical procedure that is done in a hospital or doctor’s office. General anesthesia or sedation is usually required. After the procedure, children usually go home within a few hours. Antibiotic ear drops are sometimes given after the procedure for about a week. The tubes usually come out on their own after about 6 to 12 months, but some types stay in longer. Tubes that do not come out on their own are removed by the doctor, sometimes under general anesthesia or sedation. If the opening does not close on its own, it may need to be closed surgically.
Children with ventilating tubes may wash their hair and go swimming, but some doctors recommend children do not submerge their head in deep water without using earplugs.
Drainage of fluid from the ears indicates an infection, and the doctor should be notified.
People with allergies should try to remove known allergens from their environment. Doctors may recommend people undergo treatment that stimulates the body's immune system against allergens (immunotherapy).
People with secretory otitis media should avoid or delay scuba diving and air travel, because changes in environmental pressure can cause ear pain and injury (barotrauma Barotrauma of the Ear Barotrauma is an injury caused by increased air pressure, such as during airplane flights or scuba diving. Barotrauma can cause ear pain or damage to the eardrum. The eardrum separates the ear... read more ). If air travel cannot be avoided, chewing food or drinking (for example, from a bottle) may help in young children. In older children and adults, often the pressure in the middle ear can be equalized and the discomfort can be relieved by several maneuvers. If outside pressure is decreasing, as in a plane ascending, the person should try breathing with the mouth open, yawning, chewing gum, or swallowing. If outside pressure is increasing, as in a plane descending or a diver going deeper underwater, the person should pinch the nose shut, hold the mouth closed, and try to blow gently out through the nose. This will force air through the blocked eustachian tube.
