What does a routine otology exam involve? What are the specific items for ear examination?

First of all, check the condition of the outer ear, including whether there is redness, swelling, lumps, boils and swelling of the auricle, whether there is eczema, pus, cerumen in the external auditory canal, and then check whether the tympanic membrane is complete, whether there is perforation and congestion, if you can't see clearly, you can do otoendoscopic examination, so that you can better see the specific situation of the eardrum.

If there is a hearing problem, pure tone hearing threshold audiometry and acoustic impedance test should be performed, which are the two most common tests in otology, which can determine the specific condition of hearing now, whether it is conductive deafness, neural deafness, or mixed deafness.

Acoustic impedance can indicate the presence of negative pressure in the tympanic cavity, the presence of fluid in the tympanic cavity, and the stapedius reflex. If the ear drains for a long time, an ear CT examination should be done to determine the specific conditions of the mastoid process, tympanic cavity, and inner ear.

If there is a tumor growth in the inner ear, it should also be accompanied by an MRI of the ear.

The examination of otolaryngology includes audiological examination, laryngeal examination and nasal endoscopic examination, and audiological examination includes ear endoscopy, examination of the eardrum, external auditory canal, electrical audiometry, acoustic conductance, eustachian tube function, and multi-frequency steady state nystagmus, etc., which can check the hearing condition and vestibular function. Nasal examination includes a nasal endoscope, which can examine the nasopharynx, nasal septum, turbinates, and the emotional part of the nasal cavity. There is a dynamic laryngoscope in the larynx to check the pharyngeal cavity, larynx, and vocal cords for tumors and inflammation, so otolaryngology examinations include rhinoscopy, laryngoscopy, otoscopy, and audiological examination.

There are many types of otology exams, depending on which tests are needed or what symptoms you need to consider. Generally, the simplest hearing tests include electrical audiometry, acoustic conductance impedance, and more complex and more objective ones such as brainstem evoked electricity, multi-frequency homeostasis, and sound source localization are all hearing examinations of otology; If there is a problem with the ear canal, an ear endoscopy may be done to check the ear canal or periosteum; If you have otitis media, middle ear mass, and lateral skull base mass, you need to do middle ear CT and middle ear magnetic resonance; If vertigo is a problem, vestibular function tests and electronystagmography may be done. Therefore, there are many otological examinations, and the specific examinations that are suitable for do are selected according to the different diseases and symptoms suffered.

Routine examinations include the following: internal medicine, surgery, ophthalmology, otolaryngology and stomatology, through the physical examination of the physical examination of the physical examination personnel by the doctor to find some problems, such as measuring blood pressure to find out whether there is hypertensive disease; Through the examination of color vision, it is found that there is no problem of color blindness or color deficiency; An eye test to detect eye problems. In addition, blood tests include blood glucose, blood lipids, liver function, kidney function, blood routine, urine routine, stool routine and other items, which can find out whether there are abnormal liver function in the body, high blood sugar, hyperlipidemia, hyperuricemia and other problems. Some instrument examinations, such as the examination of the anterior and lateral views of the chest, can check for tuberculosis and lung tumors, and the ultrasound examination of the liver, gallbladder, pancreas, spleen, and kidney can check for liver cysts, steatohepatitis, gallstones, gallbladder polyps, etc.

The main items of ear examination are as follows:

1. Audiological examination: pure tone audiometry, acoustic conductance test, auditory brainstem evoked potential, otoacoustic emission of distortion products, etc.

2. Vestibular function examination: it can identify whether the dizziness of the patient is caused by other lesions of the ear or central system. Patients are generally envious for 3 days before the examination, and it is forbidden to use sedative anti-dizziness drugs, and during the examination, dizziness may be induced, and patients with severe hypertension and heart disease should be cautious in the examination;

3. Imaging examination: including CT or MRI examination, CT generally observes the bony structure of the outer ear, closed middle ear and inner ear, while MRI is more suitable for finding soft tissue lesions, such as acoustic neuroma, internal auditory canal lesions, etc., which can have a better display.

What are the tests for an ear exam?

1) Ear examination in routine examination: The doctor examines the appearance of the ear through professional examination tools. Ear examination mainly includes otoscopy, eustachian tube function test, audiometry, vestibular function test, fistula test, and other tests.

Generally, the size, position, deformity and symmetry of the pinna are first observed, and whether the pinna, mastoid and periauricular lymph nodes are swollen, tender, and tender.

2) Genetic examination: many drug-induced deaf patients are overdosed on aminoglycoside antibiotics, such as gentamicin, streptomycin, kanamycin, neomycin, etc. However, if the patient does not know that he or she is a carrier of the deafness gene mutation, even if the amount is used normally, it may also lead to hearing impairment.

If the 'latent' deafness gene can be detected early through genetic screening, and the medication is taken care of, the risk can be reduced.

Otological examinations mainly include otoscopy, eustachian tube function tests, audiometry tests, vestibular function tests, fistula tests, and other related tests. It is recommended that you should go to the otology department of a regular hospital in time, and actively give corresponding ** after the relevant examination and examination are carried out to clarify the condition. Hope it helps.

Ear examination is mainly to check the hearing test and whether the structure of the ear is deformed.

Ear exams are mainly used to test hearing.

Routine checks, especially ear listening.

ENT examinations mainly include: external ear examination, eustachian tube examination, hearing examination, vestibular examination; Olfactory examination, external nasal and nasal examination, nasal function examination, nasal endoscopy; Oropharyngeal examination, laryngeal examination, etc.

Hello! Ear examination mainly includes otoscopy, eustachian tube function test, hearing test, vestibular function test, fistula test and other examinations.

First, the examinee sits on his or her side with the pinna facing the examiner; The examiner first projects the focus of the frontoscope reflection onto the opening of the external auditory canal. When adjusting the focal length, the examiner can move his or her head forward and backward so that the brightest spot of light shines on the area being examined. For pediatric patients, parents should be instructed to sit on their laps with their sides, clamp their calves between their thighs, hold their head in place with one hand, and wrap their arms around their upper body with the other hand to perform the examination.

Commonly used inspection methods are:

1) Freehand inspection method:

Stretch the pinna and tragus to straighten the external auditory canal. Because the external auditory canal is not a straight line, but slightly curved in an S-shape, it is composed of the outer 1 3 cartilage and the inner 2 3 bones, in which the direction of the outer segment is inward, backward and upward, and the direction of the inner segment is inward, forward and downward. Newborns are in the shape of a crack, and the direction of the external auditory canal of young children is inward, forward and downward, so the examination of the external auditory canal and tympanic membrane must be supplemented by certain techniques to straighten the external auditory canal, which is conducive to examination.

Two-hand examination: the examiner gently pulls the pinna backward, up, and outside with one hand to straighten the external auditory canal; With the index finger of the other hand, push the tragus forward to enlarge the opening of the ear canal so that the deep part of the ear canal and the eardrum can be seen clearly.

Examination (1) tympanic membrane: the flaccid part or the whole tympanic membrane is invaginated, which is manifested as the shortening, deformation or disappearance of the light cone, the posterior and upward displacement of the malleus stem, the obvious external protrusion of the short process of the hammer, and the smaller angle of the anterior and posterior folds. In tympanic effusion, the tympanic membrane loses its normal luster and appears yellowish, orange-red, shiny or amber, and the light cone is deformed or displaced.

Chronic patients may be grayish blue or milky white, with dilated microvessels in the tension of the tympanic membrane, short protrusions more chalky, and the thumping stem is embossed. If the fluid is serous and does not fill the tympanic chamber, the fluid level can be seen through the tympanic membrane. This liquid surface is like a curved hair, called a hairline, and the concave side is upward, and when the head position changes, its relationship with the ground remains unchanged.

Air bubbles may be seen through the tympanic membrane and may increase after the Eustachian tube is blown. Pymming otoscopy shows limited movement of the eardrum.

2) Stopper pulling: Pressing the tragus and then releasing it quickly, and testing both ears separately, the patient felt that the affected ear had a sound similar to that when pulling the cork.

3) Hearing examination: the results of the tuning fork test and the pure ** hearing valve test show conductive hearing loss. Hearing loss can vary from positive to negative, and can reach about 40dBhl in severe cases.

Because the volume of fluid fluid often varies, the hearing threshold may fluctuate somewhat. Hearing loss is generally mainly at low frequencies, but due to the changes in the structure of the middle ear and the impedance of the two springs, the hearing of high-frequency air conduction and bone conduction can also be objectively reduced, and the hearing will be improved after the effusion is discharged. The sound conduction kengram is of great value for diagnosis, and the flat type (type B) is the typical curve of secretory otitis media; The high-force type (C3 type) shows poor function of the tympachian tube, and some of them have tympanic effusion.

In patients with significant hearing impairment, auditory brainstem response and otoacoustic emission testing should be done to determine whether there is an effect on the inner ear.

4) CT scan showed that the air cavity of the middle ear system increased to varying degrees.

5) Secretory otitis media can develop into adhesive otitis media or complicated by tympanosclerosis.

What type of otitis media is, the test items are different.

It is recommended that you consult a doctor at the hospital to see what type of otitis media you have.

It is recommended that you consult a doctor at the hospital.
