What causes tinnitus?

As people age, they often feel their hearing deteriorating. Some people also experience seasonal tinnitus. Nowadays, many factors can affect our hearing. Some people like to wear headphones for a long time. Whether they are at work or school, they always wear a pair of headphones in their ears. The external noise itself is very loud. If you want to hear the sound of music, you have to turn up the volume. If people are exposed to high decibels for a long time, their hearing will naturally decline a lot.

There are many different classifications of the causes of tinnitus in medicine. Some people suffer from tinnitus due to external interference, while others suffer from the natural degeneration of hearing due to aging. Let’s take a look at the specific reasons.

Objective tinnitus is classified into:

1. Tinnitus caused by abnormally open Eustachian tube.

2. Muscle contracture tinnitus. It is easy to miss the diagnosis clinically, mostly due to abnormal movement and contracture of the tensor tympani, stapedius, tensor veli palatini and Eustachian tube pharyngeal muscles, which produce a special sound transmitted to the ear. The patient hears "click", "click", "snapping" and other similar sounds in one or both ears.

3. Vascular tinnitus mainly includes anatomical variations of the internal carotid artery and internal jugular vein, carotid artery aneurysm, jugular glomus tumor, arteriovenous fistula and giant hemangioma around the ear, which produce pulsating tinnitus when blood flows.

4. Tinnitus caused by temporomandibular joint disorder.

Classification by lesion site

Tinnitus can be divided into otopathic tinnitus and non-otopathic diseases.

Otogenic tinnitus refers to tinnitus caused by lesions within the auditory system, including external ear lesions: external auditory canal cerumen embolism or external auditory canal tumors, foreign bodies, etc.; middle ear lesions: otitis media, otosclerosis, space-occupying lesions in the tympanic cavity, high jugular bulb or jugular bulb tumor, etc.; inner ear lesions: Meniere's disease, noise-induced hearing loss, presbycusis, etc.; lesions of the retrocochlear and central auditory pathways: acoustic neuroma, multiple sclerosis, brain tumors, vascular lesions, etc. Non-otogenic diseases are diseases that originate from outside the auditory system, such as anemia, hypertension, hyperthyroidism, kidney disease, etc.
