Otitis media is generally not contagious.Otitis media generally refers to purulent otitis media, secretory otitis media and middle ear cholesteatoma, which are mostly caused by dysfunction of the Eustachian tube caused by various reasons.Such as purulent otitis media and middle ear cholesteatoma, both will be accompanied by perforation of the tympanic membrane and purulent discharge.Even if a normal person’s ear canal comes into contact with secretions through cross-contact, it will not cause otitis media infection through the intact tympanic membrane, unless there is a perforation of the tympanic membrane.The secretory otitis media, mostly secondary to upper respiratory tract infection, is a complete, closed, non-infectious inflammation of the tympanic membrane, and it is not contagious unless it is a secondary upper respiratory tract infection.
Because the baby’s ear development is not yet perfect, the Eustachian tube is short, and the position is low and straight, and its physiological isthmus is not formed. In addition, the Eustachian tube muscles are weaker and the opening in the nasopharynx is low, so the nasopharynx The fluid in the part easily flows into the middle ear.When breastfeeding, mothers usually choose to hold the breastfeeding or let the baby lie down to feed. When the baby has milk overflow and choking, it will cause the milk to flow back into the nasopharynx. The Eustachian tube enters the middle ear and causes otitis media.
Since the opening of the Eustachian tube is close to the proliferating body in the nasopharynx, and the proliferating body in infants and young children is larger, if infection occurs, the proliferating body may increase due to inflammation, making the opening in the nearby Eustachian tube easy to be affected. Infection, swelling and blockage occur due to influence, leading to otitis media.In addition to the cause of inflammation and swelling of proliferators involving the Eustachian tube, hypertrophy of proliferators, nasopharyngeal tumors, posterior nasal polyps, inferior turbinate hypertrophy, and nasopharyngeal adhesions can all cause mechanical compression of the eustachian tube. Blockage can cause otitis media; in addition, the way to blow your nose is incorrect. When colds, nasal congestion, and nasal discharge are frequent, such as blowing the nose too hard, nasal secretions can be squeezed into the Eustachian tube and then into the middle ear cavity. Otitis media.
Lie on your back and drink milk or water, causing milk to flow into your nasal cavity; often take out your baby’s ears and accidentally injure the tympanic membrane; water enters the ears when bathing and washing your hair; pinching the nose and forcibly administering medicine; taking your baby when you have a cold Some places where the pressure changes greatly, such as flying by plane; covering the nose and mouth when sneezing; and touching the ears when slapped on the child’s face.
