The treatment of otolithiasis usually starts with manipulation and repositioning, together with medication. Surgery can be considered for those with severe symptoms and recurrent disease. Surgery requires an incision, which involves cutting the skin at the mastoid process on the affected side, grinding through the mastoid bone to reach the target area, and then performing subsequent surgical operations. Surgical methods include hemicranial obstruction; posterior pudendal neurotomy, etc. 1. Semi-canal obstruction: used for refractory patients with clear diagnosis, clear lesion of the semi-canal, no improvement after more than 1 year of standardized otolith repositioning, and severe limitation of activities. 2. Posterior pudendal neurectomy: for patients with benign paroxysmal positional vertigo, whose symptoms are not relieved by conservative treatment (including medication and vestibular exercise) for more than 1 year, and who need to exclude central positional vertigo and positional vertigo caused by cervical spondylosis. If there is otolithiasis, it is recommended to go to the hospital in time, and individualized treatment plan will be formulated after clear diagnosis by specialists.
