Many people have felt dizzy at some point in their lives, but what can be called vertigo and what is associated with otologic disorders? Vertigo is a kind of motion illusion caused by the imbalance of spatial orientation and balance of the body. True vertigo” has a clear sense of rotation or tilting of oneself or other objects, and is paroxysmal, accompanied by nystagmus, balance disorders and vegetative symptoms. Pseudovertigo” (fainting) is a sense of shaking and instability of oneself or external objects, often more continuous, but it can also be paroxysmal, with mild or no accompanying symptoms. What we call vertigo is “true vertigo”. There are many causes of vertigo, including central ones such as insufficient blood supply to the basilar artery and intracranial tumors, and more peripheral ones such as Meniere’s disease, benign paroxysmal positional vertigo and ocular vertigo. There are also many systemic diseases, drug intoxication or psychiatric disorders that can cause it. Many patients with vertigo usually prefer to go to internal medicine, but many of them do not detect the related diseases or have recurrent attacks of vertigo after internal medicine treatment, so we should think that vertigo is closely related to many otologic diseases, especially those with tinnitus and hearing loss. There are many diseases that cause vertigo, among which vertigo related to otologic diseases is collectively called otogenic vertigo. What are the main symptoms? How to diagnose and treat it? The following is a brief introduction to several common diseases: 1. Meniere’s disease. Its main symptoms are episodic vertigo, fluctuating hearing loss, dullness in the ear and tinnitus. Most of the patients are middle-aged, and the main symptoms during the attack are: sudden onset, feeling the house or surrounding objects rotating when opening the eyes, and feeling the body rotating when closing the eyes, and the symptoms will be aggravated when opening the eyes or turning the head, and the patient is often accompanied by a series of symptoms such as not daring to open the eyes, nausea, vomiting, pale face, sweating, etc. when the attack is intense, but the patient remains conscious. In our clinical work, most patients diagnosed with Meniere’s disease improve significantly after symptomatic treatment such as dehydration, nerve nutrition, vasodilation and vestibular rehabilitation. The most common surgical procedures include endolymphatic bursa decompression, vagotomy, and vestibular nerve dissection. Meniere’s disease can significantly improve the symptoms after active treatment. Since hearing is prone to gradually decrease with the increase of the number of episodes, which may eventually lead to deafness, treatment should be accurate and early. 2.Benign paroxysmal positional vertigo. Paroxysmal transient vertigo is mostly induced by a specific change of head position and is not accompanied by tinnitus or deafness. Although benign paroxysmal positional vertigo is a self-healing disease, it can take months or years to heal, and in severe cases, it can cause incapacity. Some patients with frequent attacks and poor effect of medication can be cured by repositioning. This treatment method has been recognized by many patients because it is simple, non-invasive and fast/good. 3. Labyrinthitis. This is a common complication of purulent middle ear mastoiditis. These patients have a long history of chronic otitis media, especially when accompanied by cholesteatoma formation and bone destruction. Labyrinthitis often presents with paroxysmal or secondary vertigo, occasionally with nausea and vomiting. The vertigo mostly occurs during rapid turning, body flexion, in-ear manipulation (e.g., ear digging, ear washing, etc.), nose blowing, and is aggravated during acute attacks of middle ear mastoiditis. Therefore, patients with chronic otitis media should actively seek medical consultation to surgically remove the lesion and have the fistula repaired. 4. Sudden deafness. The main manifestation of sudden deafness is a significant loss of hearing within a short period of time, which may be accompanied by vertigo, tinnitus, nausea and vomiting. The effect of hormone infusion in the tympanic cavity is good in patients who have failed to recover from conventional treatment. In daily life, when we experience vertigo, we should first stay calm and relaxed; if the attack is severe and you can’t walk, you should rest in bed, avoid sound and light stimulation, and go to the hospital immediately after the vertigo is relieved, and eat a light diet with less salt, avoid stimulating food and alcohol and tobacco.
