A TMJ / ORTHODONTIC SCREEN RADIOGRAPHIC CHECKLIST

What to look for:

SUBMENTAL VERTEX -

1. Condylar morphology.

2. Relative condylar position to the horizontal baseline.

3. Mandibular asymmetry.

4. Odontoid process of C-2 spatial relationships.

 

LATERAL CEPHALOGRAM / LATERAL SKULL / LATERAL CERVICAL SPINE

1. Pharyngeal airway in area of soft palate.

2. Spatial relationship of C1 to cranial base.

3. Cervical spine contours.

4. Elevation of hyoid bone.

5. Anti-gonial notching (aka. bone deposition at the gonial angle).

6. Elongated stylohyoid processes/ossification of the stylohyoid ligaments.

 

PA SKULL (Frontal)

1. Relative height/symmetry of orbits.

2. Relative height/symmetry of mastoid processes.

3. Relative height/symmetry of gonial angles.

4. Midline symmetry of menton (symphysis).

5. Relative morphology of inferior, middle and superior nasal concha, turbinates.

6. Spatial relationships of C1 to C2.

 

PA TOWNES

1. Condylar morphology.

2. Mandibular deviation.

3. Elongated stylohyoid processes/ossification of the stylohyoid ligaments.

 

SAGITTAL/LATERAL TOMOGRAMS OF THE TMJ (same for TRANSCRANIALS

1. Relative condylar position: Right vs. Left.

2. Spatial relationships in closed, rest, open, orthotic positions.

3. Relative size and shape of respective fossae.

4. Relative morphology; size, sclerosis, degenerative changes, etc.

 

AP CORONAL/FRONTAL TOMOGRAM OF THE TMJ

1. Relative condylar morphology.

2. Elongated stylohyoid processes/ossification of the stylohyoid ligaments.

3. Oblique C1 to C2 spatial relationships.

 

PARANASAL SINUS TOMOGRAM

1. Relative morphology of inferior, middle and superior nasal turbinates.

2. Influence of concha and turbinates on left and right airway paths.
