Causes of otolithiasis may include head trauma, endocrine abnormality, otosclerosis and so on. 1. Head trauma: If the head is injured due to some external factors, it may lead to damage of soft tissues or neck bones, thus inducing otolithiasis. 2. Endocrine abnormality: Endocrine abnormality refers to the endocrine system, due to some reasons, breaks the balance state, so that the body’s hormone secretion is abnormal. If endocrine abnormalities occur in the body, hormone levels also change, and calcium metabolism in the body is abnormal, it will also induce otolithiasis. 3. Otosclerosis: Otosclerosis is due to the primary restrictive bone resorption of the bone labyrinth, which is replaced by vascularized spongy bone proliferation, which may induce otolithiasis, vertigo and so on. When otolithosis occurs, you need to go to the hospital in a timely manner, to clarify the cause of the disease to give the corresponding treatment.
