Abstract
|
|
|
The upper thoracic vertebrae through anterior approach depends upon several variables ; The diameter of the thoracic inlet. The height of the clavicles and manubrium anteriorly. And the extent of the cervicothoracic kyphosis.
Preoperatively. The upper margin of the manubrium should be compaired with the vertebral body level on standard lateral roentegenogam or mid-sagittal MRI of the upper thoracic spine. We measured the distance and the level of the corresponding
vertebra
of line A (horizontal line from the suprasternal notch to the corresponding vertebra) and line B (perpendicular line from the suprasternal notch to the anterior margin of the anterior margin of the corresponding vertebra : thoracic inlet) on
mid-sagittal MRI of normal subjects.
@ES The results were as follows:
@EN 1) In 95 cases (94 cumulative%). The line A fell to the T2 lower one thind through T4 lower one third and the mean distance was 49.8±4.2mm (means±standard deviation).
2) In 92 cases (91 cumulative%). The line B fell to the T1 lower one third to T3 middle one third and the mean distance was 45.5±4.9mm (means±standard deviation).
3) The relation of the height and the distance with age. Sex weight. Height. And body mass index were not statistically significant.
We concluded that anatomical analysis of the mid-sagittal MRI of the cervicothoracic vertebrae will be helpful in selecting the access route to the cervicothoracic lesion.
