Abstract
The paranasal sinuses of nonexpetimental laboratory animals were investigated on gross and microscopic structure and natural infection of the membrane. Large frontal sections of the sinuses were prepared and examined. The animals used consisted of each 20 mice, golden hamsters, rats, guinea pigs, rabbits, cats, dogs, and monkeys. The following results were obtained.1. Pathologic changes were found in the parnasal sinuses of 9 mice, 1 golden hamster, 20 rats, 9 guinea pigs, 6 rabbits, 4 cats, 8 dogs, and 13 monkeys.2. Infection was found to exist so frequently in the sinuses, it should be emphasized that the utmost caution is necessary in distinguishing natural changes from those prodused artificially in studies on experimental sinusitis with laboratory animals.3. Those natural changes in the sinuses of the animals corresponded in nature with the purulent type of human sinusitis.
