ear discharge
Introduction
Introduction Ear discharge, also known as ear leak, refers to the abnormal accumulation or outflow of fluid in the external auditory canal. The fluid can come from the external auditory canal, the tissue surrounding the ear, the middle ear, the labyrinth or the intracranial. Normal human ear canal has a small amount of sebaceous glands, parotid glands secrete some substances and epithelial desquamation, while some people's biochemical components of sputum mutate and secrete yellow oil, which is normal.
Cause
Cause
The skin of the normal external auditory canal has sebaceous glands, and almost all glands have a catheter opening in the hair follicle cavity. This secretion is rare and generally does not constitute an overflow. Another gland, the parotid gland, often secretes snoring, which prevents foreign bodies from deepening the human ear canal, and generally does not constitute an ear discharge. However, some people secrete more secretions, as if Vaseline accumulates in the external auditory canal and has a special odor, which is mistaken for pus. Often referred to as "oil ear", it is a normal phenomenon. When inflammation, allergic reaction or tumor occurs in the external auditory canal, serous, serous or purulent secretions may occur.
The normal tympanic and mastoid airway system is lined with cubic epithelial mucosa. Except for the glandular and goblet cells near the tympanic cavity and the eustachian tube opening, the rest have no secretory function. Normally only a small amount of mucus and water are secreted. When the middle ear is inflamed, the mucosa of the tympanic cavity and even the entire mastoid airway system has different degrees of epithelial and glandular metaplasia, and a large number of goblet cells appear, and the secretions are greatly increased, and various kinds of ear discharges are formed.

1. Otolaryngology CT examination - CT examination of the ear, nose and throat is a method of examining the ear, nose and throat by CT.
2. Electrical audiometry - is a method of recording the potential changes induced by the auditory system due to sound stimulation using modern electronic techniques.
3. Brain evoked potentials - brain function was examined by brain evoked potentials.
4. Acoustic Impedance Check - A method of checking the ear by special inspection.
5, ear, nose, throat swab bacterial culture -- the bacteria in the ear, nose, throat are from the outside, under normal circumstances, not disease. However, infection may occur due to a decrease in body or local body resistance and other external factors. Therefore, bacterial culture of ear, nose and throat swabs can isolate pathogenic bacteria and contribute to the diagnosis of otitis media, rhinitis, sinusitis, diphtheria, suppurative tonsillitis and acute pharyngitis. The specimen is taken by a doctor using a sterile cotton swab and the secretion of the patient's lesion is taken for examination.
Diagnosis
Differential diagnosis
It should be differentiated from the following symptoms:
Ear pus
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.
2. Ear canal pus
When there is inflammation in the external auditory canal or middle ear, the phenomenon of pus in the ear canal can occur. Traditional Chinese medicine treats diseases with perforation of eardrum and pus in the ear as the main symptoms, collectively referred to as pus.
3. Bloody ear leaks
Most are related to trauma, but be alert to hemangioma or middle ear cancer. Especially in middle ear cancer, blood in the pus, its pus has stench, or severe earache, headache, it is ominous. Pathological examination should be performed on the suspicious tissue in the external auditory canal or middle ear to determine the diagnosis and treatment.
