Final answer:
The swelling is caused by inflammation and accumulation of exudates, which are deflected by structures such as the condylar process of the mandible and lateral pterygoid muscle. This leads to swelling at the angle of the mandible and lateral neck.
Step-by-step explanation:
The swelling at the angle of the mandible and lateral neck is most likely a result of inflammation and accumulation of exudates. The swelling is caused by inflammation and accumulation of exudates, which are deflected by structures such as the condylar process of the mandible and lateral pterygoid muscle. This leads to swelling at the angle of the mandible and lateral neck.
This occurs when there is an infection or inflammation in the surrounding structures, such as the parotid glands or the lymph nodes in the neck. The exudates, which are fluids and proteins released during the inflammatory response, are deflected by structures such as the condylar process of the mandible and the lateral pterygoid muscle. These structures can limit the spread of the exudates and cause them to accumulate in the area, leading to swelling
