Infraorbital Nerve Orbital Floor

The infraorbital canal is a bony canal within the maxillary bone located at the anterior aspect of the orbital floor.

Infraorbital nerve orbital floor.

The infraorbital nerve travels with the infraorbital artery and vein. The roof of this infraorbital canal is only 0 23mm thick and the bone of the posterior medial orbital floor averages 0 37 mm thick. An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall typically resulting from impact of a blunt object larger than the orbital aperture or eye socket most commonly the inferior orbital wall i e. The inferior orbital neurovascular bundle comprising the infraorbital nerve and artery courses within the bony floor of the orbit.

The canal commences posteriorly as the continuation of the infraorbital groove and terminates anteriorly at the. The infraorbital nerve enters the orbit via the infraorbital fissure and passes along the floor of that structure in the infraorbital groove. In the anterior portion of the orbit the ion is in a canal and in the middle and posterior portions of the orbit it lies in a groove. The inferior orbital neurovascular bundle comprising the infraorbital nerve and artery courses within the bony floor of the orbit.

The nerve runs in the infraorbital sulcus which crosses the floor of the orbit together with the infraorbital artery and vein. If the floor is broken that nerve can be traumatized and you get numbness in the distribution of that nerve. The roof of this infraorbital canal is only 0 23mm thick and the bone of the posterior medial orbital floor averages 0 37 mm thick. Furthermore we verified patients comfort in the postoperative period because of the utmost importance to obtain further parameters useful to validate the applicability of present technique.

We also look for orbital emphysema. The floor is likely to collapse because the bones of the roof and lateral walls are robust. Infraorbital nerve transpositioning into orbital floor tioning the infraorbital nerve into the orbital floor before reduction and stabilization of the fractured zygomatic complex. The v2 nerve that goes to those structures the infraorbital nerve passes through the floor.

The patient may have blown their nose and air is pushed through the fracture and into the surrounding. It runs anteriorly along the floor of the orbit in the infraorbital groove to the infraorbital canal of the maxilla. It transmits the infraorbital nerve which is a branch of the maxillary division of the trigeminal nerve cn vb as well as the infraorbital artery and vein. The anatomy of the orbital floor predisposes it to fracture.

It branches from the maxillary nerve in the pterygopalatine fossa and travels through the inferior orbital fissure to enter the orbit. It exits the skull through the infraorbital foramen innervating the lower eyelid lateral nose and part of the superior lip.
