Abstract
The purpose of this study is to clarify the clinico-anatomical relation of the nasal septum to the lateral nasal wall.
The anatomical preparations used in this study were nasal blocks procured from 69 autopsy materials which were found to be free from diseases of the mouth, pharynx, larynx, nose and accessory sinuses. In preparing nasal blocks, much care was taken not to spoil the natural view of these anatomical structures.
Frontal sections of these blocks were made after imbedding in celloidin to facilitate observation on the topographical corelation of the nasal septum to the lateral nasal wall.
As the result of thses observations, the compensatory hypertrophy of the middle turbinate was revealed to be closely related to the shape of the nasal cavity, particularly that of the nasal septum. Furthermore, the deformity of the nasal septum, attributable to the anatomical change of the lateral nasal wall, was also observed; i.e. tubinatory deviation of the septum. The anatomical change of the lateral wall was ascertained to be the protrusion of posterior portion of the nasal cavity, namely that of the posterior ethmoid cells direced toward the septal side.
In this connection, state of rima olfactoria was examined also to reveal some cases with abnormal form to exist, which had not been hitherto observed. The abnormality of rima olfactoria in shape was also found to be closely related to pathological changes of the accessory sinuses.
The author arrived at a conclusion that emphasis should be laid on the necessity to draw attention on the above mentioned pathological forms of the anatomical features when one preforms a reconstructive operation of the nasal cavity.
