Airway Management
Published in Elizabeth Combeer, The Final FRCA Short Answer Questions, 2019
Nasal air passages = ophthalmic and maxillary divisions of trigeminal nerve: Anterior septum and nares: anterior ethmoidal nerve (V1).Elsewhere: greater and lesser palatine nerves (V2).

The greater and lesser palatine nerves supply both the hard and soft palates and carry with them postganglionic parasympathetic fibers. Remember that the nerve of the pterygoid canal (Vidian nerve) enters the ptery-gopalatine fossa, is connected anteriorly to the pterygopalatine ganglion, and carries preganglionic parasympathetic axons from the greater petrosal nerve and postganglionic sympathetic axons from the deep petrosal nerve (Plates 3.20 and 3.39; described in detail in Section 3.3.1.5). The lesser palatine nerve and the greater palatine nerve carry these fibers from the pterygopalatine ganglion through the greater palatine canal and pass through the lesser and greater palatine foramina, respectively.

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.
Quantitative sensory testing for assessment of somatosensory function in human oral mucosa: a review

One study showed that the PPT in the palate was 40% lower in complete-denture-wearing patients than dentate subjects, indicating that wearing a denture may make the mucosa more sensitive to painful pressure stimuli [79]. Functional disturbance in the nasopalatine and greater palatine nerves have also been indicated in complete denture wearers [80]. Moreover, a negative correlation between bite force and PPT was found in the palatal, maxillary and mandibular posterior regions in edentulous patients, which may add another reason for denture pain practice [79].
Bilateral suprazygomatic maxillary nerve block versus palatal block for cleft palate repair in children: A randomized controlled trial

As regards palatal block, our results showed better postoperative analgesia in PB group compared to control group. The palate receives sensory innervation from naso palatine, greater and lesser palatine nerves. Blocking these nerves provides adequate palatal analgesia.
