Where is the infraorbital region?
The infraorbital region is a component of the midface and can be defined as the anatomical area between the nasal aperture and the zygomatic bone below the inferior rim of the orbit and above the roots of the maxillary canine and premolars (Fig. 6.1).
What is infraorbital a branch of?
The infraorbital nerve (ION) is the terminal branch of the maxillary nerve; it supplies the skin and mucous membranes of the middle portion of the face. This nerve is vulnerable to injury during surgical procedures of the middle face.
What is the infraorbital?
Anatomy. The infraorbital nerve is a purely sensory nerve derived from the second maxillary division of the trigeminal nerve. The infraorbital nerve is a terminal branch that exits the skull through the foramen rotundum to enter the pterygopalatine fossa.
Where do you find infraorbital notch?
#5. Vertical distance from the AIOF to the infraorbital margin. #6. Horizontal distance from the AIOF to the lacrimal caruncle.
Where is infraorbital notch?
The infraorbital foramen is located in the maxillary bone. It is the anterior opening of the infraorbital canal, which is the anterior continuation of the infraorbital groove, which course through the floor of the orbit. The canal may reside entirely in the maxillary sinus, suspended from the sinus roof by a mesentery.
What is the Auriculotemporal nerve a branch of?
trigeminal nerve
The auriculotemporal nerve is a tributary of the mandibular division of cranial nerve five, the trigeminal nerve. It contains sensory, vasomotor, and parasympathetic fibers.
Is Infratrochlear a nerve?
The infratrochlear nerve is an extraconal branch of the nasociliary nerve, a branch of ophthalmic division of the trigeminal nerve. Some authors describe it as the terminal branch of the nasociliary nerve.
What is posterior superior alveolar?
The posterior superior alveolar nerve, also known as the posterior superior dental nerve, is the first branch of the infra-orbital nerve, from the maxillary division of the trigeminal nerve. It is the first of the superior alveolar nerves and contributes to the superior dental plexus.
What is the landmarks for Infraorbital artery?
The following bony and dental landmarks were identified for the IOF: the infraorbital rim, the cusps of the second premolar, the piriform aperture, and the lateral orbital rim.
Where is the infraorbital region located?
The infraorbital region is the facial region located below the orbital region, lateral to the nose, and above the buccal region. Text by Antoine Micheau, MD – Copyright IMAIOS
What is the intraoral approach to block the infraorbital nerve?
The intraoral approach to block the infraorbital nerve is achieved by advancing a 27-gauge needle along the inner surface of the lip and cephalad to the infraorbital foramen parallel to the maxillary premolar.
What is the meaning of inferior orbital region?
in·fra·or·bit·al re·gion. the facial region below the orbit and lateral to the nose on each side. in·fra·or·bit·al re·gi·on. Facial area below orbit of the eye and lateral to nose on each side.
How do you palpate the infraorbital foramen?
To palpate the infraorbital foramen, have the patient look straight ahead and imagine a line drawn vertically (sagittally) from the pupil down toward the inferior border of the infraorbital ridge. Keep the palpating finger in place over the inferior border on the infraorbital rim for the remaining steps.
