People who experience a sudden hearing loss (SSNHL) are often treated with systemic steroids, which are taken orally. Studies however show that people with sudden sensorineural hearing loss (SSNHL) who do not respond to this treatment can benefit from intratympanic steroid injections. Studies carried out at universities in USA and Thailand show intratympanic steroid injections to be very effective and that the treatment does not have any side-effects.
Dr. David Haynes from Vanderbilt University Medical Center, Nashville, USA, carried out the study of 40 people who had experienced sudden sensorineural hearing loss (SSNHL). Overall, 40% showed some kind of improvement when treated with intratympanic steroid injections.
The most commonly used AAS in medicine are testosterone and its various esters (but most commonly testosterone undecanoate , testosterone enanthate , testosterone cypionate , and testosterone propionate ),  nandrolone esters (most commonly nandrolone decanoate and nandrolone phenylpropionate ), stanozolol , and metandienone (methandrostenolone).  Others also available and used commonly but to a lesser extent include methyltestosterone , oxandrolone , mesterolone , and oxymetholone , as well as drostanolone propionate , metenolone (methylandrostenolone), and fluoxymesterone .  Dihydrotestosterone (DHT; androstanolone, stanolone) and its esters are also notable, although they are not widely used in medicine.  Boldenone undecylenate and trenbolone acetate are used in veterinary medicine .
