The tissues in the throat rub on the styloid process during the act of swallowing with resulting pain along the glossopharyngeal nerve. There is also pain upon turning the head or extending the tongue. Other symptoms may include voice alteration, cough, dizziness, migraines, occipital neuralgia, pain in teeth and jaw and sinusitis or bloodshot ...
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.

Its originates from the styloid process of the temporal bone; it inserts onto hyoid bone. It is innervated by a branch of the facial nerve . It acts draw the hyoid bone upwards and backwards.
Two parts of the hyoid arch: the styloid process. In the dog the styloid process is represented by a series of four articulating bones, from top down tympanohyal, stylohyal, epihyal, ceratohyal; the first two represent the styloid process, and the ceratohyal represents the anterior horns of the hyoid bone and articulates with the basihyal which ...
The stylohyoid branch of facial nerve provides motor innervation to the stylohyoid muscle. [1] [2] It frequently arises from the facial nerve (CN VII) in common with the digastric branch of facial nerve. [1] It is long and slender. [3] It enters the stylohyoid muscle at the middle portion of the muscle. [1]
The stylopharyngeus is a long, slender, [1] [2] tapered pharyngeal muscle. [2] It is cylindrical superiorly, and flattened inferiorly. [1]It passes inferior-ward along the side of the pharynx [1] between the superior pharyngeal constrictor (situated deep to the stylopharyngeus) and the middle pharyngeal constrictor (situated superficial to the stylopharyngeus), [2] before spreads out beneath ...
The average distance between the opening of the stylomastoid foramen and the styloid process is around 0.7 mm or 0.8 mm in adults, but may decrease to around 0.2 mm during aging. [1] The stylomastoid foramen transmits the facial nerve, [2] [3] and the stylomastoid artery. [3] These 2 structures lie directly next to each other. [3]
The parapharyngeal space is divided into 2 parts by the fascial condensation called the aponeurosis of Zuckerkandl and Testut (stylopharyngeal fascia - see diagram), [3] joining the styloid process to the tensor veli palatini. These two compartments are named the pre-styloid and post-styloid (retrostyloid) [4] compartments or
