What is the reason for the baby's earwax to smell?

Nowadays, people’s living environment is relatively clean, and parents pay great attention to their children’s hygiene. Some parents even bathe their babies every day. Sometimes parents may accidentally get bath water into their baby's ears when bathing them. In this case, they can only clean the baby's ears with a cotton swab, but some babies' ears actually have a bad smell. What is the reason for the baby's earwax to smell?

1. Suppurative otitis media

(1) Acute suppurative otitis media is an inflammation of the middle ear caused by suppurative bacterial infection. Its main symptoms are ear pain and pus discharge. Children's systemic symptoms are more obvious than those in adults, and may include fever, vomiting, etc. Serious complications include intracranial complications such as meningitis, brain abscess, etc. Other complications include labyrinthitis, facial nerve paralysis, etc.

(2) Chronic suppurative otitis media refers to chronic suppurative inflammation of the middle ear mucosa, periosteum or deep into the bone. This disease is relatively common in clinical practice, and its main clinical manifestations are intermittent or continuous pus discharge in the ear, tympanic membrane perforation, and hearing loss. In severe cases, it can cause intracranial and extracranial complications. ① Systemic symptoms vary in severity. There may be fear of cold, fever, fatigue, and loss of appetite. Children have more severe systemic symptoms, often accompanied by gastrointestinal symptoms such as vomiting and diarrhea. Once the eardrum is perforated, the body temperature will gradually drop and systemic symptoms will be significantly alleviated. ② Earache: Pain deep in the ear that gradually worsens. Such as throbbing or stabbing pain, which may radiate to the same side of the head or teeth. Ear pain worsens when swallowing and coughing. Severe ear pain can cause insomnia and restlessness at night. After the eardrum perforated and pus flowed out, the ear pain suddenly subsided. ③ Ear discharge is the main symptom of this disease, which can be mucous, mucopurulent or pure purulent. Non-dangerous pus discharge is thinner and has no odor. Although the dangerous type of pus discharge is not much, it is thicker, mostly pure purulent, and accompanied by a foul odor. ④ Hearing loss and tinnitus: The patient begins to feel stuffy in the ears, followed by a gradual decrease in hearing, accompanied by tinnitus. Deafness may be ignored in patients with severe ear pain. Some patients may experience vertigo, and deafness may be alleviated after perforation. ⑤ The severity of deafness varies, and because it usually occurs in one ear, it is easily overlooked. It is usually conductive hearing loss.

2. Non-suppurative otitis media and secretory otitis media.

(1) Hearing loss Acute secretory otitis media can often cause hearing loss after a cold, while descending on an airplane or diving, and may also be accompanied by a phenomenon of "self-enhancement of the sound". The severity of hearing loss in patients with chronic secretory otitis media often fluctuates. Hearing may improve when the tragus is compressed or the head position is changed. When the middle ear fluid is thick, hearing will not change with changes in head position. Most children do not complain of hearing loss, but may ignore their parents' calls, have difficulty concentrating, or request too loud a volume when watching TV.

(2) Earache: Acute secretory otitis media may cause mild earache, while chronic secretory otitis media may cause earache during secondary infection.

(3) A feeling of stuffiness or blockage in the ear.

(4) Tinnitus is usually not severe and may be intermittent. The sound of air passing through water may be heard when the head moves, yawns, or blows the nose. A small number of patients with secretory otitis media may also experience water discharge in the ears, but the duration is very short, only a few hours or about a day.

(5) Otoscopic examination revealed radial vascular striae around the tympanic membrane during the acute phase. The tense part of the tympanic membrane is invaginated, manifested by shortening, deformation or disappearance of the light cone; the handle of the malleus is displaced backward and upward; and the short process of the malleus protrudes significantly outward. When tympanic cavity effusion occurs, the tympanic membrane loses its normal luster and becomes light yellow, orange-red or amber; in chronic cases, the tympanic membrane becomes milky white or gray-blue and opaque. If the secretion is serous and does not fill the tympanic cavity, the liquid level can be seen through the tympanic membrane as a concave upward arc line. Bubbles can sometimes be seen through the tympanic membrane, and the number of bubbles increases after the Eustachian tube is expanded. If there is a lot of fluid in the tympanic cavity, the tympanic membrane will protrude and the mobility of the tympanic membrane will be limited.
