Concerning excentration of the mastoid cells in tympanoplasty the author has expressed an opinion in the foregoing articles that the mastoid cells should not be excentrated in majority of the cases of chronic otitis media of the mucositis type, because the inflammation findings in the retrotympanic space (retrotympanitis) shows a marked healing tendency, particularly in this antibiotic age.As for the flap in tympanoplasty, the isolated tubal shaped skin flap was taken from the osseous meatus and its terminal end which correspond to the ring of the tympanic membrane was sutured. This reconstructed tube-shaped skin meatal flap was repositioned in the osseous meatus, adjusting the adaptation of its end to the ossicles. This functions as a new tympanic membrane.
