External auditory canal tumor
Introduction
Introduction to external auditory canal The most common clinical manifestations of external auditory canal include exogenous epiphyseal papilloma and parotid gland, and most of the primary benign tumors are malignant tumors. The tumor is asymptomatic in the early stage, and it is blocked, itchy or hearing loss when it is filled with the external auditory canal. Often there are those who dig ear bleeding or dig out "meat pieces". With secondary infection, there may be earache and pus. It can be seen that the external auditory canal has single or multiple hairs of different sizes, rough surface, pedicled or pedicled brown-yellow mass, which is hard to touch. Infected people can be swollen and granulated. Those with local blood circulation disorders can be black and can partially fall off naturally. Rapid proliferation can invade the middle ear and mastoid, and even under the auricle to form a fistula. basic knowledge The proportion of sickness: 0.9% Susceptible people: no special people Mode of infection: non-infectious Complications: tinnitus, external auditory canal, otitis media
Cause
External ear canal tumor cause
Cause:
May be associated with UV exposure. Exposure to squamous cell carcinoma of the ear canal may be associated with inflammatory stimuli in chronic otitis externa or chronic otitis media.
Prevention
External auditory canal cancer prevention
1. Always educate your children not to smother small things into their ears.
2. Adults must quit their ears with a matchstick and a toothpick.
3. After having a foreign body, go to the hospital and take it out by the doctor.
4. The ear canal after removing foreign objects should be kept dry and clean.
The tumor is asymptomatic in the early stage, and it is blocked, itchy or hearing loss when it is filled with the external auditory canal. Often there are those who dig ear bleeding or dig out "meat pieces". Earache may occur with secondary infection.
Complication
External auditory canal tumor complications Complications, tinnitus, external auditory canal, otitis media
With secondary infection, there may be earache and pus.
Squamous cell carcinoma of the external auditory canal is often invasive, can quickly invade the bone tissue underneath, and can involve the facial nerve.
External auricular adenoid cystic carcinoma can cause tinnitus and conductive hearing loss. Patients with longer course of disease may be accompanied by secondary infections and ear leaks, such as otitis externa and otitis media.
Symptom
Symptoms of external auditory canal tumors Common symptoms Ear canal foreign body ear canal block external ear canal pain ear canal bleeding
Small tumors without infection can be diagnosed according to their appearance, and most of them should be diagnosed by disease.
The tumor is asymptomatic in the early stage, and it is blocked, itchy or hearing loss when it is filled with the external auditory canal. Often there are those who dig ear bleeding or dig out "meat pieces". With secondary infection, there may be earache and pus. It can be seen that the external auditory canal has single or multiple hairs of different sizes, rough surface, pedicled or pedicled brown-yellow mass, which is hard to touch. Infected people can be swollen and granulated. Those with local blood circulation disorders can be black and can partially fall off naturally. Rapid proliferation can invade the middle ear and mastoid, and even under the auricle to form a fistula.
If the infection is secondary, the ear is painful and pus. Check that the tumor is more than the outer segment of the external auditory canal, and even exposed to the external auditory canal. The base is generally wide, the number of sizes is different, and the surface is uneven, such as mulberry. When there is no secondary infection, the color is brown and firm; if it is secondary infection, it is congested and swollen, and sometimes the tumor may turn black due to local blood circulation disorder.
The tumor has strong proliferation and destructive power, which can invade the middle ear and mastoid. Some form a fistula behind the auricle. If there is a secondary infection, the fistula will bleed and bleed. Even the bottom of the external auditory canal can be worn to form the pharyngeal fistula. The other end is open to the upper abdomen. At this time, it is difficult to open the mouth.
The disease has a tendency to malignant, should pay attention to check whether there are swollen lymph nodes around the ear.
Examine
Examination of external auditory canal tumors
The local examination is mainly for the external auditory canal. The cartilage mass is located in the anterior and inferior wall of the external auditory canal. The base is extensive and hard. The surface of the tender mass is intact (except for infection). The tender tumor may also be in the form of a ring-shaped hard knot to make the outer ear canal stenosis grow out. The skin has a red granulation-like bloody purulent exudate in the external auditory canal.
Diagnosis
Diagnosis of external auditory canal tumor
diagnosis
Typical external auditory canal cholesteatoma is not difficult to diagnose by otoscopy.
Differential diagnosis
It needs to be differentiated from external auditory canal embolization and external auditory epithelial plug. When there is stinky pus and / or granulation in the external auditory canal with infection, it should be differentiated from cholesteatoma otitis media. Small tumors without infection can be diagnosed according to their appearance, and most of them should be diagnosed by disease.
