Dear Sir, First thing you have to understand is that tinnitus is not a disease and it is a symptom to some problem in your auditory system. Through your report it is evident that you have high frequency hearing loss and that may also be one of the reasons for your tinnitus, but I would suggest you go for tympanometry, TDT and SISI tests for better understanding of your hearing problem. Tinnitus may increase or decrease with time, it depends on how you take care of your hearing loss and how easily you get habituated with tinnitus. Please consult your audiologist personally or me online for better guidance. Thank you

High frequency hearing loss usually in both ears indicate noise induced damage. Do u work in noisy surroundings ? Do u use much of ear phones ?? Avoid noise exposure. Use ear muffs or plugs to protect urself from noise. Use tablet Nurac Od which is neuro protective. If u avoid noise exposure and use this tablet it may stop progressing. Otherwise it may progress to a level where u need to use hearing aid.  Ur left Max sinus mucosal thickening may be due to the infection following tooth cleaning. Ur dental condition is responsible for sinus infection. ND sinus infection inturn may lead to ear problems. But u r suffering from sensorineural hearing problem for which sinus is not responsible. For tinnitus u can try tablet tinnicar once daily . If there is an organic cause for tinnitus on treating the cause d tinnitus will subside. If it is non organic u need to adjust with it. U need to consult ENT physician to rule out acoustic neuroma . For which ur doctor may advice MRI contrast.
