This may be a controversial statement, but I think tinnitus is strongly linked to obstructive sleep apnea. It's been shown that untreated sleep apnea patients have multiple areas of brain issue injury and damage, especially in the are of the brainstem where the auditory nerves enter (as well as other various areas). Brainstem auditory nerve testing has been shown to be significant more diminished in sleep apnea patients, with more viscous (thicker) blood that's more prone to clot and block small arteries. Treating sleep apnea with either CPAP or diluting the patient's blood improved these brainstem responses to sound waves. The inner ear has a very delicate vascular supply and any slowing, clotting or blockage of this vessel can have devastating consequences on any part of auditory/vestibular system.
Traditionally, tinnitus is treated as a neurologic problem to many different and conflicting explanations and treatment options. Unfortunately, there's no definitive cure for this all too common condition. What I've seen, however, is that almost every patient who comes in for tinnitus has the anatomy and history strongly suggestive for obstructive sleep apnea. Sometimes, treating the sleep apnea definitively helps with the tinnitus. Unfortunately, since there can be various degrees of permanent nerve damage, and responses to OSA are inconsistent.
Dr. Park just thinking out loud here.. could there be an association between Ménière's syndrome and sleep apnea. A few of my patients have had surgery for Ménière's syndrome and have sleep apnea. just wondering if the two could have some corellation in development.
