The mastoid process is the portion of the temporal bone of the skull that is behind
Parotitis presents as swelling at the angle of the jaw. Bacterial parotitis presents as a unilateral swelling, where the gland is swollen and tender and usually produces pus at the Stensen's duct.

Each gland lies behind the mandibular ramus and in front of the mastoid process of the temporal bone. The gland can be felt on either side, by feeling in front of each ear, along the cheek, and below the angle of the mandible. [4] The parotid duct, a long excretory duct, emerges from the front of each gland, superficial to the masseter muscle.
It usually occurs in children and involves pain in front of the ear, swelling of the parotid, fever, chills, and headaches. [2] Bacterial sialadenitis is usually caused by ascending organisms from the mouth. Risk factors include reduced salivary flow. Human immunodeficiency virus-associated salivary gland disease (HIV-SGD). [1]
Pneumoparotitis (also termed pneumosialadenitis [1] wind parotitis, [1] surgical mumps, [2] or anaesthesia mumps), [2] is a rare cause of parotid gland swelling which occurs when air is forced through the parotid (Stensen) duct resulting in inflation of the duct. [3]
But here’s some encouraging news: No matter the source of your swollen under-eyes, there are products to use, actions to take, and lifestyle changes that can be implemented to help get rid of ...
Ear pain due to an infection is the most common in children and can occur in babies. [10] Adults may need further evaluation if they have hearing loss, dizziness or ringing in the ear.
