External auditory canal superimposed on internal auditory canal 2. Mastoid air cells 3. Tegmen 4. Lateral sinus plate 5. Temporo mandibular joint. (Key area of the mastoid, i.e. attic, aditus and antrum are not well seen) Schuller's view Similar to Law's view but cephalocaudal beam makes an angle of 30deg to the sagittal. Structures seen are: 1. External canal superimposed on internal canal 2. Mastoid air cells 3. Tegmen 4. Lateral sinus plate 5. Condyle of mandible 6. Sino-dural angle 7. Antrum and upper pa of attic (i.e. key area).
