The pathophysiology of the pain related to elongated SP was thought to be due to the compression of the nerves such as the lower branch of the trigeminal nerve, glossopharyngeal nerve
and/or the chorda tympani.
It then gives branches over the preauricular and temporal areas. The parasympathetic chain to parotid consists of the preganglionic fibers that originate in the inferior salivatory nucleus and travels with the glossopharyngeal nerve
, tympanic nerve, and lesser petrosal nerve to the otic ganglion.
Third arch overgrows the second so the root is supplied by glossopharyngeal nerve
. Superior laryngeal nerve innervates the epiglottis and extreme posterior part of tongue and they develop from fourth arch.
For example, the following descriptions are found for the glossopharyngeal nerve
. In the retro-olivary groove (Arana & Rebollo, 1979; Bustamante, 2007) or post-olivary fissure, the vagus nerve is found, which emerges behind the olive, as do the glossopharyngeal and accessory nerves (Carpenter, 1994).

in patients with Eagle syndrome: surgical technique and outcomes in a series of 5 patients," Journal of Neurosurgery, vol.
This in turn may stimulate the branches of the greater and lesser palatine nerve, glossopharyngeal nerve
, and facial nerve, which may result in widespread painful sensation following the peripheral distribution of the nerve.
Glossopharyngeal neuralgia (GPN) is a very sporadic condition related to hyperactivity of the glossopharyngeal nerve
Examination also revealed paralysis of the left hypoglossal nerve and the left glossopharyngeal nerve
. Left vocal fold paralysis was seen on fiberoptic laryngoscopy.
The clinical symptoms characteristic of a carotid sinus syndrome (i.e., repeated fainting and falling), which are believed to be associated with carotid sinus nerve or Hering's nerve, in turn, a branch of the glossopharyngeal nerve
, if disappear after the surgical removal of the tumor, constitute a unique case.[sup]
Preoperative intravenous dexamethasone combined with glossopharyngeal nerve
block: role in pediatric postoperative analgesia following tonsillectomy.
Neurofibromas of head and neck may arise form cranial nerves like the trigeminal nerve (TGN), uncommonly the facial nerve, glossopharyngeal nerve
, or upper cervical nerves [9, 10].
In cats, it results from activation of a reflex whose afferent fibres originate from the pharyngeal branch of the glossopharyngeal nerve
, and the efferent ones from the vagal motoneuron, projecting to the phrenic nerve and laryngeal intrinsic muscles.
