Intratympanic N-Acetylcysteine for Prevention of Cisplatin-induced Ototoxicity.
Ototoxic Hearing LossAlthough many intratympanic agents have been attempted, N-Acetylcysteine (NAC) appears to be the most promising and is a powerful, commonly used anti-oxidant. The goal of this prospective phase 2 randomized controlled trial is to determine the optimal dosage and effectiveness of intratympanic NAC injection in reducing hearing loss in head \& neck cancer patients receiving cisplatin chemotherapy with curative intent.
