These fibers originate in the inferior salivatory nucleus in the medulla and travel via the tympanic nerve (Jacobson's nerve) to the middle ear from which they continue as the lesser superficial petrosal nerve that synapses in the otic ganglion. Postganglionic fibers supply the parotid gland.

The tonsils receive their nerve supply from the tonsillar plexus, a complex meshwork of nerves originating from the tonsillar branches of the maxillary nerve and the glossopharyngeal nerve. The fibres of the maxillary nerve are distributed to the lesser palatine nerves (although they pass through the pterygopalatine ganglion, they do not synapse there) and via these nerves are then combined with the glossopharyngeal nerve to form their plexiform arrangement of nerves around the tonsils. This plexus also supplies the oropharyngeal isthmus and the soft palate. An offshoot of the glossopharyngeal nerve, the tympanic nerve, also supplies the tympanic cavity and the tympanic membrane. Consequently, any pathology affecting the tonsils or the tonsillar fossa may present as pain referred to the ear.

One case of postoperative sensorineural hearing loss was reported in the microscopic group (loss of BC > 15 dB). Six (21%) patients in the endoscopic group and 19 (40%) in the microscopic group suffered from vertigo after surgery, with the difference not being statistically significant (p = 0.104). When postoperative vertigo was divided into whirling type and non-whirling type, 3 cases (50%) of endoscopic group and 6 cases (32%) of microscopic group suffered from vertigo showed whirling type vertigo, and there was no significant difference between the endoscopic group and microscopic group (p = 0.630). There was no facial palsy in either group. The chorda tympanic nerve was found and saved in all cases. Postoperative dysgeusia were reported in 2 cases (4.2%) of the microscopic group and none (0%) of the endoscopic group at 2-4 weeks after surgery. There was no statistical significance between two groups (p = 0.528). There was no patient who complained dysgeusia at 1 year follow up (Table 2).
