The infraorbital nerve is often blocked with local anesthetic to induce analgesia. This may be due to chronic pain, [2] or during dental or surgical procedures of the face such as for the management of postoperative pain associated with cleft lip correction.
The clinically important structures surrounding the orbit include the optic nerve at the apex of the orbit as well as the superior orbital fissure which contains cranial nerves 3, 4, and 6 therefore controlling ocular muscles of eye movement. [15] Inferior to the orbit is the infraorbital nerve which is purely sensory.
The maxillary sinuses are housed within the maxillary bone, and traumatic injury to these sinuses may cause sinus infections, and changes in eye placement and movement. [4] The infraorbital nerve (a terminal branch of CNV2) courses through the maxillary bone and provides sensation to the central face. Additionally, the maxillary bone contains ...
In most cases, there is loss of sensation in the cheek and upper lip due to infraorbital nerve injury. Facial bruising, periorbital ecchymosis, soft tissue gas, swelling, trismus, altered mastication, diplopia, and ophthalmoplegia are other indirect features of the injury. [1]
The anterior superior alveolar nerve (or anterior superior dental nerve) is a branch of the infraorbital nerve (itself a branch of the maxillary nerve (CN V 2)). [1] It passes through the canalis sinuosus to reach and innervate upper front teeth. Through its nasal branch, it also innervates parts of the nasal cavity.
A woman whose foot turned outwards, causing her to stumble in pain during a night out drinking thought she’d “twinged a nerve” — but it was a brain tumor pressing on the part of her brain ...
Forming the exterior end of the infraorbital canal, the infraorbital foramen communicates with the infraorbital groove, the canal's opening on the interior side.. The ramifications of the three principal branches of the trigeminal nerve—at the supraorbital, infraorbital, and mental foramen—are distributed on a vertical line (in anterior view) passing through the middle of the pupil.
Dana Carvey was one of the biggest former “Saturday Night Live” stars not to attend “SNL50” last week. Now, we know why. Carvey, known during his time on “SNL” for such characters as ...
