Prevention of Cisplatin-Induced Hearing Loss by Intratympanic Dexamethasone Treatment

"0.7ml of Dexamethasone Phosphate 10mg/ml would be injected unilaterally to the middle ear using 25 gauge spinal needle.~The trans-tympanic membrane injection would take place at the posterior inferior quadrant of the ear drum facing the round window niche. The patient would be instructed to lie down for 20 minutes after the injection with the treated side up and to avoid swallowing or coughing. Intratympanic Dexamethasone would be delivered immediately prior to each cisplatin treatment as maximal level."
