Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

Eventually, subperiosteal bone formation may give a firm swelling. Trismus (difficulty opening the mouth), which may be present in some cases and is caused by edema in the muscles. Dysphagia (difficulty swallowing), which may be present in some cases and is caused by edema in the muscles. Cervical lymphadenitis (swelling of the lymph nodes in ...
The pain is more usually unilateral (located on one side) rather than bilateral. [20] It is rarely severe. [25] Limited range of mandibular movement, [2] which may cause difficulty eating or even talking. There may be locking of the jaw, or stiffness in the jaw muscles and the joints, especially present upon waking. [19]
The digastric muscle (also digastricus) (named digastric as it has two 'bellies') is a bilaterally paired suprahyoid muscle located under the jaw.Its posterior belly is attached to the mastoid notch of temporal bone, and its anterior belly is attached to the digastric fossa of mandible; the two bellies are united by an intermediate tendon which is held in a loop that attaches to the hyoid bone.
Soft tissue swelling visibly resulting in enlargement of the hands, feet, nose, lips, and ears, and a general thickening of the skin; Soft tissue swelling of internal organs, notably the heart with the attendant weakening of its muscularity, and the kidneys, also the vocal cords resulting in a characteristic thick, deep voice and slowing of speech
In humans, the mandible, or lower jaw, is connected to the temporal bone of the skull via the temporomandibular joint. This is an extremely complex joint which permits movement in all planes. The muscles of mastication originate on the skull and insert into the mandible, thereby allowing for jaw movements during contraction.
Temporomandibular disorder (TMD, also termed "temporomandibular joint pain-dysfunction syndrome") is pain and dysfunction of the TMJ and the muscles of mastication (the muscles that move the jaw). TMD does not fit neatly into any one etiologic category since the pathophysiology is poorly understood and it represents a range of distinct ...
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 ...
