Study of histopathological changes in atrophic rhinitis.

A punch biopsy from the inferior turbinate was taken in 71 consecutive cases of atrophic rhinitis and studied for histopahtological changes. Squamous metaplasia was seen in 85 percent of cases. Tunica propria showed granulation tissue (41 percent) and chronic inflammatory cellular infiltrate (32 percent). Mucosal glands were decreased in 42 percent of cases and absent in 28 percent. Areas of dilated vessels were observed in 35 percent and decreased vascularity in 59 percent of cases. These observations are similar to those reported by others. Total squamous metaplasia with keratinisation and hypertrophy was seen by us in one case. This has not been reported earlier.
