嗅裂部粘膜の肥厚について

抄録

The mucosa of the Rima olfactoria of the nasal septum was examined microscopically. Frontal sections of the nasal and paranasal cavities were prepared from 63 autopsy cases between the ages of two mcnths and 62 years.
Hypertrophy was confirmed in 9 case (14.3%). This condition was most frequently encountered and remarkable at the posterior region of the nasal septum and followed in the order of the middle and anterior region, respectively. The cases after adolescence greatly outnumbered those of the younger age group, and it was more frequently found in males than in females. Furthermore, this condition occurred frequently in those with hypertrophy of other portions of the nasal cavity, in those with pathologic lesions of the ethmoid sinus, and in those with a large Rima olfactoria.
It is considered that the majority occurs from a chronic inflammatory irritation, especially of the posterior portion of the ethmoid sinus and sphenoidal sinus.This condition has a great clinical significance, and more attention should be given to this condition during inspection and operation of the nasal and paranasal cavities.
