A hiccup ear thumping, may be hiccups when the air pressure changes and other physiological factors, may also be cerumen impaction, temporomandibular joint disorder syndrome and other pathological factors lead to.
1. Physiological factors: spasmodic contraction of the diaphragm during hiccups causes changes in air pressure inside and outside the middle ear, which opens the Eustachian tube at the moment of hiccups to regulate the air pressure inside and outside the middle ear, so that the pressure inside and outside the ear can be balanced with the atmospheric pressure. The change of air pressure during hiccups can cause the mechanical vibration of tympanic membrane and auditory ossicles chain, which is transmitted to the inner ear to produce auditory response, i.e., thumping sound.
2. Pathologic factors:
(1) Cerumen embolism: foreign body entry, otitis externa, stenosis of the external auditory canal and other factors can cause blockage of the external auditory canal, when hiccups cause changes in air pressure inside and outside of the middle ear, the airflow can displace the cerumen, resulting in cackling ringing.
(2) temporomandibular joint disorder syndrome: can be caused by internal and external trauma, depression, anxiety, autoimmune factors such as difficulty in opening the mouth, joint popping and other symptoms, hiccups when opening the mouth, can be caused by the temporomandibular joint popping, through the ear to the auditory center, resulting in thumping of the ears.
A hiccups ear thumping, it is recommended to consult a doctor in order to clarify the diagnosis, under the guidance of the doctor for targeted treatment.
