Abstract

Purpose:
The purpose of this study is to investigate the effect of the vestibular system on the bone formation process and the possible path of this effect. Also, in the present study, an attempt has been made to provide evidence related to this effect and its importance in clinical work.
Methods:
For this review article, the keywords "bilateral vestibulopathy", "bone regeneration", "sympathetic vestibular reflex" and "sympathetic nervous system" were searched from 1980 to 2022 in the "google scholar" and "pub Med" databases.
Results:
After searching the mentioned sources of information, a total of 13 articles were obtained. Among these articles, 8 were research articles (animal and human studies). Therefore, the results of these 7 articles were used for discussion and conclusions
Conclusion:
Recent studies have stated that the vestibular system may play a role in the bone regeneration process through the effect on the sympathetic system. The vestibular system is a small part of the auditory system located in the inner ear in the temporal bone. The vestibular system has many connections with important centers in the brain stem. On the other hand, the sympathetic nervous system also acts as an intermediary mechanism through which the central nervous system exerts its effects. The presence of these extensive and complex connections, which are both upward and downward, justifies the influence of the vestibular system on bone regeneration.
