Otovestibular investigations are of great importance in industrial medicine whenever poisoning by chemicals is suspected. CO is the oldest and commonest poison with rhino-cochleo-vestibular symptoms and 80 suspected cases are reported here. The symptoms were compared between the confirmed cases and those which were not. A diminution in the sense of smell was noted in the former. The cochlear findings showed a perceptive disturbance with a high tone loss and largely retroganglionic damage. Subjective symptoms included vertigo which was accompanied by nystagmus more commonly in the confirmed group than in the other. One study shows that giving a medico-legal opinion on doubtful CO poisoning, the otologist's diagnosis is important in confirming or rejecting evidence of intoxication. The question arises whether the prescribed serial medical examination of personnel exposed to CO should be extended from the 5 yearly audiometric tests in practice now, to obtain valuable data for possible future use, in making a medioco-legal assessment. This measure would be welcome by industrial medical officers engaged in reporting on industrail injuries.
