Overview
The ear goes through the external auditory meatus from the auricle that collects surrounding sounds, reaches the eardrum, and travels from the eardrum made of three thin layers to the middle ear.After going through three small bones that amplify sound in the middle ear, the strength, height and lowness of sound are analyzed and recognized by the cochlea located in the inner ear, and the sense of balance is maintained by the vestibule and the semicircular tube.External otitis media is an infectious disease that occurs on the skin of the external auditory canal, the path from the auricle to the eardrum.The main symptoms are pain and itching.Because otitis externa often occurs after swimming, it is sometimes called a swimmer′s ear.It is often caused by earpicks using cotton swabs or the like, which damage the external auditory canal.cause
External otitis media is a condition in which the skin of the external auditory canal is inflamed, and the cause of the wound is that the external auditory canal is scratched with earpick or finger nails, and bacteria are infected with the wound, causing inflammation.Patients with allergies, psoriasis, eczema and dermatitis are also said to be susceptible to external otitis.In addition to using a cotton swab or a match stick or toothpick instead of a cotton swab to damage the external auditory canal, irritants such as hair spray and hair dye can easily develop into the external auditory canal.Also, when water enters the external auditory canal, it often causes inflammation, especially after swimming in the water.symptom
The main initial symptoms are pain, itching and redness.Many patients are worried about itching, so they pick their ears hard, which can further damage the external auditory canal and worsen the symptoms.When the symptoms progress, the ears may produce secretions that smell white or yellow.Some patients may not get swollen, but others may have difficulty hearing if the swelling is severe or if secretions such as pus and ear drops get stuck in the external auditory canal.In general, pulling the earlobes or pushing the ears often causes pain.When fungi such as Aspergillus are infected from the wound, black and yellow dots are formed, and sticky milky white secretions are often produced when infected with Candida bacteria.In addition, blood may come out when the swelling in the external auditory canal is crushed.examination and diagnosis
Diagnosis is often made by visual examination of the external auditory canal.At the time of diagnosis, the patient is examined for symptoms or the external auditory canal is examined with an instrument for examining the external auditory canal and the eardrum to confirm the condition.When identifying bacteria such as Staphylococcus aureus, aspergillus, and fungi that cause inflammation, such as Candida, pus and secretions are collected and cultured to investigate pathogens.In doing so, it is important to determine the difference from malignant otitis, which causes inflammation of the external auditory canal as well as external otitis.Malignant external otitis media is an infectious disease caused by pus green bacteria that spreads to surrounding tissues and spreads to the base of the skull.treatment
As for treatment, it is important to remove infected earwax, earwax and other secretions and cleanse them, and keep them dry inside the inside of the ears.Bacteria are the cause of otitis externa, and if the patient′s symptoms are mild, ear drops containing acetic acid and ear drops containing corticosteroids may be prescribed.In severe cases, antimicrobial drugs or ear drops are prescribed.Antibacterial drugs such as antibiotics may also be prescribed as internal medicines.In addition, if a patient complains of pain, they should prescribe painkillers until the inflammation begins to subside.If the cause of otitis externa is fungus, treat it by removing secretions and scraps from the external auditory canal and applying antifungal drugs or ear drops.If the wound in the external auditory canal is likely to become suppurative and pus is likely to come out, or if it cannot be removed by prescription, the pus is removed by a direct incision.precautions after prevention/treatment
Because infecting bacteria and fungi from the wound of the external auditory canal is the cause of otitis externa, it is important to keep in mind your daily life without damaging the external auditory canal.You should be careful not to overpick your ears, or to allow irritating hairspray or hair dye to enter the external auditory canal.Earwax itself protects the external auditory canal from bacterial infection, and it is effective to avoid forced earpick or swab cleaning that can damage the external auditory canal.
