Final answer:
The degree of pt face rotation from the lateral position in the oxiolateral (Law) method of demonstrating the mastoid process is determined by the angle of the X-ray beam, which is typically around 15-20 degrees.
Step-by-step explanation:
In the oxiolateral (Law) method of demonstrating the mastoid process, the degree of pt face rotation from the lateral position is determined by the angle of the X-ray beam. The angle of rotation can vary depending on the specific technique used, but typically it is around 15-20 degrees.
It is important to note that the oxiolateral (Law) method is an X-ray technique used to visualize the mastoid process, which is a bony prominence located behind the ear. The method involves positioning the patient in a lateral position and angling the X-ray beam towards the mastoid process to obtain a clear image.
For more specific and accurate information on the degree of pt face rotation in the oxiolateral (Law) method, it is recommended to refer to academic textbooks or consult with a radiologist or an anatomy expert.
