With 22 corpses of various age ranges the length and width of Rosenmüller's fossa (R. fossa) were measured, and macroscopic observations were carried out on the conditions of lymphoid tissues in R. fossa in the case of infants and on the remaining lymphoid tissues as well as the adhesions in R. fossa in the cases of older children and adults.
As the results it has been found that in the case of infants adenoids filled up R. fossa, extending up close to Torus tubaris; in the case of older children adenoids in R. fossa tended somewhat involuted and the adhesions of upper commissure were revealed; and in the case of adults various adhesions were found mainly in the upper commissure of R. fossa, bridging across the posterior upper part or the posterior lower part.
In addition, the morphological observation and measurements were taken of R. fossa with serial horizontal cross sections prepared from 5 corpses ranging 12 months to 26 years in age. In all of them irrespective of age the upper commissure was of the wide and shallow form, the central part the transitional form, and the lower commissure the narrow and deep form, whose width and depth at the portal were measured and measurements were presented in the main context.
