Ear discharge

Introduction Ear pus is also known as ear leak and is a common symptom of ear disease. When the ear is pus, attention should be paid to the nature, quantity and odor of the pus for identification. In the case of external auditory canal, there may be watery secretions. Acute otitis externa, external auditory canal eczema, external auditory canal, external ear canal mycosis, and inflammation of the external auditory canal secondary to external auditory canal cholesteatoma, external auditory canal, and external auditory canal. Benignity of the external auditory canal (such as papilloma) and malignant tumors can also cause external auditory canal discharge.

Cause

Related to the following diseases.

1. Foreign ear disease:

Acute otitis externa, external auditory canal eczema, external auditory canal, external ear canal mycosis, and inflammation of the external auditory canal secondary to external auditory canal cholesteatoma, external auditory canal, and external auditory canal. Benignity of the external auditory canal (such as papilloma) and malignant tumors can also cause external auditory canal discharge.

2. Middle ear disease:

Bullous tympanitis, acute suppurative otitis media, tympanic membrane perforation, various types of chronic suppurative otitis media, middle ear tuberculosis, middle ear cancer, etc.

3. Other diseases:

Such as cerebrospinal fluid ear leaks, fistulas that open in the external auditory canal.

1. Physical examination:

Pay attention to the properties, color and smell of the secretions. Serous or purulent secretions mixed with blood, mostly acute suppurative otitis media or external auditory canal fistula, cerebrospinal fluid otorrhea is a continuous, colorless transparent watery liquid, may be reddish but not coagulated when mixed with blood, cholesteatoma The otitis media has a small amount of pus, but it has a strange smell. The secretion of tuberculous middle ear mastoiditis has a special odor. At the same time, pay attention to whether there are foreign bodies, sputum plugs, cholesteatoma, new organisms in the external auditory canal, whether the skin is congested, swollen, and whether there is a fistula opening. Whether the tympanic membrane has bullae, perforation, whether there is a tumor in the tympanic cavity, cholesteatoma, whether there is redness and tenderness in the mastoid area.

2. Laboratory inspection:

If suspected middle ear mastoid lesions should be X-ray or CT examination, suspected cerebrospinal fluid otorrhea should check the sugar content of the liquid and perform X-ray examination of the skull base. If new organisms in the middle ear are found, biopsy should be performed early. Purulent secretions should be tested for bacterial culture and drug susceptibility.

Differential diagnosis

It should be distinguished from "oily sputum", which is caused by excessive secretion of the parotid gland. The secretion is yellow or dark brown paste or honey-like, often with a genetic predisposition.
