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. This pus is usually sampled and the bacteria within are identified. Common causative bacteria are Staphylococcus aureus, Streptococcus pyogenes and E ...
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.
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle.
3. Facial swelling – usually unilaterally and affecting parotid region, under the tongue, or below the jaw. May have acute onset and may have a history of repeated episodes. 4. Recurrent painful swellings – indicative of chronic recurrent sialadenitis, may have similar signs and symptoms to an acute episode. 5.
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]
Localized lymphadenopathy: due to localized spot of infection; e.g., an infected spot on the scalp will cause lymph nodes in the neck on that same side to swell up; Inflammatory localized lymphadenopathy at right mandibular angle. Generalized lymphadenopathy: due to a systemic infection of the body; e.g., influenza or secondary syphilis
The facial lymph nodes comprise three groups: (a) infraorbital or maxillary, scattered over the infraorbital region from the groove between the nose and cheek to the zygomatic arch;
Rarely, a ranula may descend into the neck rather than the mouth (plunging ranula). If small, the ranula may be left alone; if it is larger and causing symptoms, excision of the sublingual gland may be indicated. Nicotinic stomatitis is whitening of the hard palate by hyperkeratosis caused by the heat from smoking or from drinking hot liquids ...
