SMG morphologic measurement definitions
| Morphologic Measurement | Definition | Direction of Measurement |
|---|---|---|
| AP length | As measured between anteriormost border of gland and posteriormost border of SMG | On axial images, perpendicular to axis connecting the mandibular condyles |
| AP length difference | Difference between the AP lengths of the SMGs by subtraction of the AP length of the contralateral gland from the transferred gland | On axial images, perpendicular to axis connecting the mandibular condyles |
| Posterior margin difference | Distance between the posteriormost border of the gland and that of the contralateral gland | On axial images, perpendicular to axis formed by connecting the mandibular condyles |
| Superior margin difference | Distance between the superiormost border of the gland and that of the contralateral gland | On coronal images, perpendicular to axis formed by connecting the mandibular condyles |
| Anteroinferior margin difference | Distance between the anteroinferior-most border of the gland and that of the contralateral gland | On axial images, perpendicular to axis formed by connecting the mandibular condyles |
Note:—AP indicates anteroposterior.
