Otitis externa – Inflammation of the external auditory canal and / or the bell of the pavilion – causes severe pain, initially unconnected to stabbing, subsequently becoming contiguous with night exacerbations and reaching the ear pavilion; the pain may spread to areas around the ear.
Otitis externa. Other symptoms of external otitis include hearing impairment, hearing loss, swelling of adjacent areas, purulent secretion from the external auditory tube.
Factors that cause otitis externa are bacteria and fungi that normally colonize the skin from the external auditory canal.
Intact skin is a natural barrier to microbial aggression as well as cerumen.
The situations that these obstacles change are:
- ear washing with soap, shampoo, spirits
- underwater swimming, water sports (polo)
- chronic eczema that occurs with itching in the ear and the formation of a yellow crust
- using ear sticks can cause lesions that are the gateways for bacteria and fungi
- (diabetes, tuberculosis, cancer, HIV infection, long-term cortisone treatment)
- physiological situation (pregnancy)
It's a myth that "you get infected from swimming pools or seawater." In fact, moisture in the skin humorates the skin and creates entry gates for bacteria and "common localization" mushrooms.
Often, in the case of otitis, the condition is good without fever or chills, with obvious local discomfort.
In situations of immunodepression, otitis externa may have a malignant nature with fulminant development and a poor general condition requiring hospitalization and infusion therapy.
Otitis externa. Evolution depends on the correctness of treatment:
- local – daily tables with rivanol exchanged until local pain disappears after antibiotic drips in the external auditory duct
- generally – anti-inflammatory, antibiotic
Typically, gold staphylococcus produces otitis externa under the conditions of local and general alterations listed above, so the most common is an antibiotic against the pharynx – oxacillin or ciprofloxacin.
Initially, pain is intensified even if the treatment is already in place (infection is localized), especially at night. Then the purulent collection "breaks" and pauses the pain. From now on, treatment will be local until complete healing, shows the medical center Dr. Diagnosis and treatment of "Dr. Victor Babes".
Hearing restoration and hearing loss appear gradually, requiring repeated auricular aspirations to clean secretions that mix with local drops and debris.
It is not necessary to collect secretion from the external auditory canal for the determination of bacteria and / or fungi, except in the case of relapsing otitis, diabetes, other general causes of immunodepression.
Mycotic otitis external is not painful! – it manifests by clogging the external auditory conduction through the mycelial plug and testifying to possibly black secretion.
If bacterial infection is associated with mycotic otitis, pain and local swelling occur – this is otitis externa mixed.
In this case, priority is to suppress pain through anti-inflammatory and antibiotic drugs, even though antibiotic therapy promotes the development of fungus; later, after pain relief, severe local mycotic otitis – drops of alcoholic boric acid and diluted betadine are treated. No general antimycotic treatment is necessary, except immunodepression.
Otitis externa. Differential diagnostics include:
- early mandibular arthritis
- pharino-amigdalitis, acute tonsillitis
- dental disability
- acute otitis media, acute otomastoiditis
However, external otitis can not be associated with some of these conditions!
Any persistent ear pain is a consultation with ENT in order to diagnose or exclude optic disease.
