That suggests patients with tinnitus could have damaged auditory nerves that no longer send signals to their brains, potentially resulting in brain activity that causes patients to hear sounds of ...
Extrinsic anomalies are structural changes near the Internal Jugular Vein (IJV) that can cause venous outflow obstruction. These changes can be due to bone pressure, artery pressure, enlarged lymph nodes, or an enlarged thyroid. These factors can squeeze the vein wall and block the blood flow.
Hearing loss may have many different causes, but among those with tinnitus, the major cause is cochlear injury. [36] In many cases no underlying cause is identified. [2] [38] Ototoxic drugs also may cause subjective tinnitus, as they may cause hearing loss, [15] or increase the damage done by exposure to loud noise. [39]
The headache can be made worse by any activity that further increases the intracranial pressure, such as coughing and sneezing. The pain may also be experienced in the neck and shoulders. [5] Many have pulsatile tinnitus, a whooshing sensation in one or both ears (64–87%); this sound is synchronous with the pulse.

[2] [3] Causes of a primary CSF leak are those of trauma including from an accident or intentional injury, or arising from a medical intervention known as iatrogenic. A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. [4] A lumbar puncture can give the symptom of a post-dural-puncture headache.
Nasal congestion can interfere with hearing and speech. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea or upper airway resistance syndrome. [5] In children, nasal congestion from enlarged adenoids has caused chronic sleep apnea with insufficient oxygen levels and hypoxia.
Vestibular schwannoma, erroneously known as Acoustic neuromas, and other types of brain tumours can cause hearing loss by infringement of the tumour on the vestibulocochlear nerve; Viral diseases of the ear can cause sensorineural hearing loss usually as the consequence of labyrinthitis. The person may be generally unwell at the time.
