The rattling of the right ear when the head moves may be caused by the movement of cerumen touching and rubbing the tympanic membrane under normal circumstances; it may also be caused by the presence of cerumen embolism, otitis media, and cervical spondylosis. 1. Cerumen embolism: If dust and debris enter the external auditory canal, excessive cerumen secretion, malformation of the external auditory canal, etc., the cerumen accumulates in the external auditory canal and coagulates into lumps, which may move with the head movement and produce abnormal rattling sound. 2. Otitis media: when the patient is affected by localized infection of the middle ear, dysfunction of the Eustachian tube, air pressure injury and other factors, there is a buildup of fluid, which will be inherited with the head movement, resulting in tinnitus. 3. Cervical spondylosis: when cervical spondylosis, joint movement is limited, and when the head turns, the joint friction may rattle sound. It is recommended that patients go to the hospital in a timely manner, under the guidance of the doctor, to conduct a detailed examination, a clear diagnosis.
