 Chondroitin sulfate is used in 65 cases of nerve deafness, 126 ears, which were found to be established by various causes such as toxicosis, occupational noises, trauma, causes unknown and senility. The dosage consisted of 60mg of the drug administered daily by intravenous route. Subjective improvement of hearing occurred in 50% of the total number of cases. The improvement of hearing by audiogram substantiated 40%. The response with improvement seemed to take place most readily in those loss of hearing that occurred by exposure to occupational noises and which were followed by those that were caused by toxicosis and causes unknown ; by audiographic types those who showed diptype were most responsive and followed by horizontal and acutely descending types. The use of the drug appeared to be the more effective the lesser the loss and the period of that involvement. The effectivity was seen for improvement in 60% cases of tinnitus aurium.
