Cerumen embolism
Introduction
Introduction to embolization The skin of the external auditory canal has a parotid gland that secretes a pale yellow viscous liquid, which is called sputum. Some scorpions like mucus, commonly known as "oil ear". Under normal circumstances, you can use your chewing, mouth opening and other mandibular movements to discharge them in the form of thin slices. If the sputum gradually aggregates into a mass, block the external auditory canal, and call it an impactedcerumen. Embolization of sputum should be distinguished from epidermal pedicle, which is also called cholesteatoma of the external auditory canal. It is caused by chronic inflammation of the external auditory canal and is caused by epidermal detachment. It is characterized by continuous exfoliation of the epidermis, continuous enlargement of the epidermis, and compression of the external auditory canal to enlarge it. Or oppression of the tympanic membrane causes deafness, and the epidermal plug is expansive to water or secondary to acute inflammation, which can cause severe pain. basic knowledge The proportion of illness: 0.021% Susceptible people: no specific people Mode of infection: non-infectious Complications: deafness
Cause
Embolism
Excessive secretion or discharge of the parotid gland, such as narrow external auditory canal, foreign body retention, osteophytes and so on.
Prevention
Embolization prevention
1. Do not dig your ears at all times.
2. After removing the cockroach, pay attention to keep it clean and dry.
Complication
Embolism complications Complications
If not treated properly, it can cause deafness.
Symptom
Embolization symptoms Common symptoms Hearing loss Tinnitus, earache, dizziness, deafness, multiple ear canal blockage
Hearing loss, tinnitus, earache, and even dizziness may occur. After expiration, the sputum expands and completely blocks the external auditory canal, which may cause hearing loss. It may also stimulate the external auditory canal to cause external auditory canal inflammation. If the tympanic membrane is stimulated by stimulation, tinnitus may occur, occasionally due to oppression. The ear causes vertigo.
Examine
Embolization check
It can be seen that the brownish black or yellowish brown mass blocks the outer ear canal.
Diagnosis
