This study focuses on idiopathic sudden sensorineural hearing loss, a condition where hearing suddenly deteriorates without a known cause. The study aims to determine if adding hyperbaric oxygen treatment to standard care can improve hearing outcomes better than standard care alone. Hyperbaric oxygen involves breathing pure oxygen in a pressurized chamber.
During the study, participants will receive either standard care treatment alone or standard care combined with hyperbaric oxygen therapy. The treatment involves breathing a mixture of nitrous oxide and oxygen through inhalation. The maximum treatment period is 16 days, with each session lasting up to 95 minutes. The total treatment time may reach up to 1520 minutes across all sessions.
Hearing ability will be measured using various tests throughout the study period, with a particular focus on hearing levels after three months of treatment. The study will track changes in hearing ability, word recognition, and how the treatment affects participants’ daily communication abilities and overall quality of life.
