Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla bone.
On an x-ray, cysts appear as radiolucent (dark) areas with radiopaque (white) borders. [7] However, cysts in maxillary sinus, also known as antrum, can appear radiopaque as the surrounding air absorbs fewer photons than the cystic fluid content. Cysts are usually unilocular, but may also be multilocular.
Expansion of the cyst causes erosion of the floor of the maxillary sinus. As soon as it enters the maxillary antrum, the expansion rate increases due to available space for expansion. Performing a percussion test by tapping the affected teeth will cause shooting pain. This is often clinically diagnostic of pulpal infection. [citation needed]
The pyramid-shaped maxillary sinus (or antrum of Highmore) is the largest of the paranasal sinuses, located in the maxilla. It drains into the middle meatus of the nose [ 1 ] [ 2 ] through the semilunar hiatus .
Mucous retention cyst in maxillary sinus indicated by the asymmetrical blue lump to the right of the nose. The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth.
This picture shows important anatomy involved in endoscopic endonasal surgery. The pituitary gland sits at the top of the picture behind the sphenoid sinus. This approach is the most common and useful technique of endoscopic endonasal surgery and was first described in 1910 concurrently by Harvey Cushing and Oskar Hirsch.
The maxillary sinus is known for its thin floor and close proximity to the posterior maxillary (upper) teeth. [ 1 ] [ 6 ] The extraction of a maxillary tooth (typically a maxillary first molar which lies close to the lowest point of antral floor although any premolar or molar can be affected) is the most common cause of an OAC (which can then ...
Complications from endoscopic sinus surgery are rare, but can include bleeding and damage to other structures in the area including the eye or brain. [21] Many physicians recommend a course of oral steroids prior to surgery to reduce mucosal inflammation, decrease bleeding during surgery, and help with visualization of the polyps. [12]
