With the accelerated pace of life, the pressure of work and life brings us a sense of suffocation, and various diseases also emerge quietly, and vertigo is the second most common clinical symptom after pain, and it is becoming more and more common regardless of gender or age. How much do we know about this common condition? ”Doctor, my dizziness is always bad, and the doctor suggested I come to the ENT department.” In clinical work, otolaryngologists often encounter such patients. Many patients do not understand why they need to see ENT for dizziness. In fact, vertigo is caused by ENT diseases in the vast majority of patients, such as Meniere’s disease, otoliths, vestibular neuronitis, vestibular paroxysm, sudden deafness with vertigo, etc. Dizziness is a clinical symptom, yet not a separate disease. There are many kinds of dizziness, a symptom that can touch multiple diseases and involve multiple systems of the body. It is a relatively broad concept with complex and diverse clinical manifestations, including vertigo, a feeling of dizziness and dullness, and a feeling of mental unconsciousness. Patients often confuse these symptoms, in fact, there is a difference between vertigo and dizziness and insensibility, vertigo is a symptom with more clinical diagnostic specificity and is a subjective symptom, which is an orientation sensory disorder or balance sensory disorder of the body in relation to space, also known as motion illusion. Patients have the illusion that the surrounding scenery rotates, shakes up and down or moves from side to side when they open their eyes, while they have the illusion of their own rotation or shaking when they close their eyes, often accompanied by balance disorders, nystagmus, finger deflection, nausea, vomiting, pallor, sweating and changes in pulse and blood pressure, and even with hyperactive bowel movements and frequent bowel movements. According to the etiology, vertigo can be divided into two categories: peripheral vertigo and central vertigo. Peripheral vertigo refers to vertigo caused by lesions of the vagus or vestibular nerve in the inner ear, which accounts for more than 70% of vertigo. This type of vertigo is mostly associated with otolaryngological diseases, such as benign positional vertigo (commonly known as otoliths), Meniere’s disease (Meniere’s disease), vaginitis, drug-related vertigo (caused by drugs such as streptomycin or gentamicin) and vestibular neuritis. Therefore, patients with this type of vertigo should first visit the ENT department. After a certain understanding of vertigo, you may have questions again, that is, why should patients with vertigo see the ENT department? Here we go deeper to understand the characteristics of common vertigo diseases in ENT for your convenience in the future: 1. History is important in the diagnosis of benign paroxysmal positional vertigo, which has distinctive features: firstly, rotational vertigo; secondly, the duration is usually less than 30 seconds; thirdly, it is excited by head movement (when lying down, when turning over, bending over and lifting the head, washing the head, etc.). 2. The diagnosis and treatment of some diseases such as auditory neuroma, large vestibular aqueduct syndrome and superior semicircular canal cleft syndrome require patients to visit the ENT department in person. 3, Vaginitis and vestibular neuritis often have a history of colds and infections. 4, Typical clinical manifestations of Ménière’s disease include: episodic vertigo, fluctuating and progressive hearing loss, tinnitus, and ear swelling and fullness.
