Anatomy and Embryology of the Mouth and Dentition

The sensory nerves to the palate are derived from the greater and lesser palatine and nasopalatine branches of the maxillary nerve (Figure 41.10) These nerves pass through the pterygopalatine ganglion. The greater palatine nerve descends through the greater palatine canal, entering the hard palate at the greater palatine foramen. It then passes forwards on the bony palate towards the canine tooth, supplying the gums and the mucosa and glands of the hard palate (excluding the anterior teeth). As it leaves the greater palatine canal, palatine branches are also distributed to the soft palate. The smaller lesser palatine nerves descend through the greater palatine canal to emerge through the inconspicuous lesser palatine foramina and give branches to the uvula, tonsil and soft palate. Fibres conveying taste impulses from the palate probably pass via the palatine nerves to the pterygopalatine ganglion (see Figure 41.10) and through it to the nerve of the pterygoid canal and then the greater petrosal nerve to reach the facial ganglion, where their somata are situated. Parasympathetic postganglionic secretomotor fibres run in the facial nerve through its greater petrosal nerve to reach the pterygopalatine ganglion to be distributed in the palatine nerves, thereby reaching palatine mucous glands.

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.

In addition, Obayah et al. [28], evaluated the effect of the addition of dexmedetomidine to the local anesthetics in bilateral greater palatine nerve block in children presented for cleft palate repair under general anesthesia and revealed that dexmedetomidine prolonged the duration of greater palatine nerve block. Also, Fyneface-Ogan et al. [29], who evaluated the addition of either fentanyl or dexmedetomidine as an additive in single shot spinal anesthesia for labour analgesia and demonstrated that the use of dexmedetomidine was associated with a better analgesic properties as compared to the use of fentanyl.
