The greater palatine foramen is located at a level approximately equal to the distal surface of the maxillary fourth premolar tooth and midway between the palate midline and dental arch. The major palatine artery, vein and nerve exit this foramen, and course along the length of the palate in the palatine sulcus.
Also question is, what goes through the greater palatine foramen?
The greater palatine foramen is the opening in the posterior hard palate of the greater palatine canal, which is formed between the articulation of maxillary bone and the greater palatine sulcus of palatine bone. It transmits the greater palatine nerve and vessels to the palate.
Furthermore, where does the greater palatine nerve come from? The greater palatine nerve (anterior palatine nerve) is a branch of the pterygopalatine ganglion that carries both general sensory fibres from the maxillary nerve and parasympathetic fibers from the nerve of the pterygoid canal.
Keeping this in consideration, where do you give a greater palatine nerve block?
Greater Palatine Nerve Block
- Place a cotton swab at the junction of the hard palate and the maxillary alveolar process.
- Starting in the region of the maxillary first molar (or second primary molar in the primary dentition) apply pressure with the cotton swab while moving posteriorly.
Where is the Palatine process located?
(Palatine process labeled at bottom right.) Inferior surface of maxilla. In human anatomy of the mouth, the palatine process of maxilla (palatal process), is a thick, horizontal process of the maxilla. It forms the anterior three quarters of the hard palate, the horizontal plate of the palatine bone making up the rest.

What passes through the lesser palatine foramen?
Behind the greater palatine foramen is the pyramidal process of the palatine bone, perforated by one or more lesser palatine foramina which carry the lesser palatine nerve, and marked by the commencement of a transverse ridge, for the attachment of the tendinous expansion of the tensor veli palatini.
What passes through the greater and lesser palatine foramen?
Maxillary nerve The greater palatine foramen provides a passage for the greater palatine nerve. The lesser palatine nerves pass through the lesser palatine foramina, which are situated just behind the greater palatine foramen (see Fig.
What passes through Pterygomaxillary fissure?
The pterygomaxillary fissure transmits the posterior superior alveolar nerve, a branch of maxillary division of the trigeminal nerve from the pterygopalatine fossa to the infratemporal fossa. Terminal branches of the maxillary artery also enter the fissure.
Where does foramen Rotundum open?
Foramen Rotundum. The foramen rotundum is located at the base of the greater wing of the sphenoid, inferior to the superior orbital fissure. It provides a connection between the middle cranial fossa and the pterygopalatine fossa. The maxillary nerve (branch of the trigeminal nerve, CN V) passes through this foramen.
Where is the sphenopalatine foramen?
The sphenopalatine foramen is a foramen in the skull that connects the nasal cavity with the pterygopalatine fossa. The processes of the superior border of the palatine bone are separated by the sphenopalatine notch, which is converted into the sphenopalatine foramen by the under surface of the body of the sphenoid.
What does the lesser palatine nerve supply?
The lesser palatine nerve, a branch of the maxillary nerve, provides sensory innervation to the soft palate. The tensor veli palatini muscle is innervated by the mandibular nerve through the branch to the medial pterygoid muscle. Almost all soft palate tumors arise on the oral surface.
What goes through the pterygoid canal?
The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the sphenoid bone, inferomedial to the foramen rotundum. It transmits the Vidian artery and Vidian nerve from the middle cranial fossa to the pterygopalatine fossa.
What is in the Pterygopalatine fossa?
In human anatomy, the pterygopalatine fossa (sphenopalatine fossa) is a fossa in the skull. A human skull contains two pterygopalatine fossae—one on the left side, and another on the right side. It is the indented area medial to the pterygomaxillary fissure leading into the sphenopalatine foramen.
What does the greater palatine artery supply?
The greater palatine artery is a branch of the descending palatine artery (a terminal branch of the maxillary artery) and contributes to the blood supply of the hard palate and nasal septum.
Why is Nasopalatine nerve block painful?
Nasopalatine Nerve Block. The nasopalatine nerve innervates the palatal tissues of the six anterior teeth. If the needle is inserted into the nasopalatine foramen, it is possible to completely anesthetize the six anterior teeth. However, this technique is painful and not used routinely.
Are there nerves on the roof of your mouth?
As they pass through the sphenopalatine ganglion, these sensory branches form the greater and lesser palatine nerves, which provide sensory innervation to the nasal cavity as well as the roof of the mouth, soft palate, and tonsils. It provides sensory innervation to the anterior portion of the nasal cavity.
How do you give a shot Asa?
Approach: While retracting the lip, insert the needle into the intersection of the mucobuccal fold and the apex/center of the canine at a 45-degree angle, advancing the needle approximately 1-1.5 cm. Aspirate. Slowly inject 2 mL of local anesthetic and massage for 10-20 seconds.
How do you give a long buccal nerve block?
How is the buccal nerve block performed? Landmarks: Locate the buccal nerve 1 mm lateral to mandibular molar 3 at the anterior border of the ramus in the occlusive plane. Apply topical anesthetic as described in the Anesthesia section. Approach: With the thumb of the nondominant hand, pull the cheek laterally. Aspirate. Slowly inject 2 mL of local anesthetic.
What Innervates the hard palate?
Sensory innervation of the oral cavity is supplied by the branches of the trigeminal nerve (CN V). The hard palate is innervated by the greater palatine and nasopalatine nerves, both of which are branches of the maxillary nerve (CN V2). The cheeks are innervated by the buccal nerve.
How do you give a mental nerve block?
Intraoral Identify the mental foramen (as described above in Anatomy) Retract the lower lip and apply a topical anesthetic to the base of the first bicuspid at the inferior labial sulcus for approximately 60 seconds. Insert a small-gauge needle with a small syringe of anesthetic to approximately 1 cm depth.
What is the function of a hard palate?
The hard palate sits at the front of the roof of the mouth and contains the palatine bone. The hard palate makes up two-thirds of the palate. It provides structure in the mouth and allows space for the tongue to move around.
What is Vidian nerve?
Vidian nerve, also known as the nerve of the pterygoid canal or nerve of the Vidian canal, is so named because of the canal in which is travels: the Vidian canal. greater superfical petrosal nerve (from the geniculate ganglion of the facial nerve) carrying parasympathetic fibers from the superior salivary nucleus.
