The author studied the results of 1949 tympanometries in 981 patients with middle ear infections and summarized the results as follows:
1) Many cases of acute otitis media in children showed type B tympanograms during convalescence from infections. The frequency of type A increased in elder children. Only a few cases showed type C in adult patients.
2) Regular monthly follow-up of patients with acute otitis media showed a tendency for tympanograms to return more rapidly to normal in older children than in younger children.
3) The paracentized ears required longer periods before their tympanograms returned to normal than did the non-paracentized ears.
