Tinnitus is a common clinical symptom with many causes. However, for some tumors, tinnitus is an early symptom that can not be ignored, and it is also one of the main causes of patients seeking medical treatment.
According to a clinical survey data: in the analysis of the clinical manifestations of 800 cases of NPC and 50 cases of brain neuroma, 62% of them found tinnitus symptoms. Tinnitus is the patient’s self feeling of sound in the ear. The performance of each person is quite different, such as cicadas, insects, clocks, wind, machines and so on. These symptoms often upset the patient and affect life. Why does nasopharyngeal carcinoma produce tinnitus?
This is because the nasopharynx tumor with infection and edema blocked the opening of eustachian tube in the side wall of nasopharynx. The symptoms were tinnitus on the ill side, which was gradually aggravated, and hearing loss. Therefore, in case of persistent tinnitus of unknown cause, it is necessary to check it in the otolaryngology department of the hospital in time, make clear diagnosis, eliminate tumor and treat it in time.
The main treatment of NPC is radiotherapy. After radiotherapy, most patients still have tinnitus and hearing loss for a long time. The reason for this phenomenon is that the tissue around the eustachian tube is fibrotic after the nasopharynx is exposed to a large amount of radiation, and the normal opening and closing of the eustachian tube orifice can not be controlled temporarily.
On the other hand, after radiotherapy, the nasopharynx showed chronic inflammatory changes, secretion blocked the orifice of pharyngeal drum, and tinnitus also occurred. Tinnitus will disappear gradually with the repair of pathological tissue.
Therefore, tinnitus can not be ignored.
