In the patients with adhesive otitis media, the mucosa of the inferior turbinate was transplanted to the site on the medial wall of the middle ear where the mucosa was missing to prevent recurrent adhesion.
Histomorphological investigation was made using light and transmission electron microscopies of the mucosa of the inferior turbinate to be transplanted, normal promotory mucosa, the middle ear promontory mucosa of the non-adhered region in the cases of adhesive otitis media and the middle ear mucosa to which the mucosa of the inferior turbinate was transplanted. The postoperative courses of 10 cases undergone staged operations were favorable, showing no recurrence of adhesion in any of them. We could not decide whether the transplanted mucosa of the inferior turbinate took as middle ear mucosa in all cases. However, it was considered that this staged operative method by which the mucosa of the inferior turbinate is transplanted is useful for preventing recurrence of adhesion by securing the middle ear cavity.
Many of the epithelia of the middle ear mucosa to which the mucosa of the inferior turbinate was transplanted were cuboidal epithelia with less goblet cells, showing a difference from the pseudostratified epithelium peculiar to the mucosal epithelium of the inferior turbinate. In the lamina propria, no clear zone and nasal glanduler tissue which is characteristic in the mucosa of the inferior turbinate was observed in the middle ear promontory mucosa to which the mucosa of the inferior turbinate was transplant-ed. However, the middle ear mucosa closely resembling the mucosa of the inferior turbinate was observed in 1 case. In this case, no nasal glandular tissue was observed, But, it suggested that the mucosa of the inferior turbinate transplanted takes as middle ear mucosa and keep a part of the charactaristic of the mucosa of the inferior turbinate.
