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.
Both maxillary first molars have the same letter; "D". However, the right molar has the symbol "┘" underneath it. The left molar has "└" underneath it. In the international system of notation two numbers are used to identify the tooth. The right deciduous maxillary first molar is known as "54", and the left one is known as "64".
The endoscopic approach to FESS is a less invasive method than open sinus surgery, which allows patients to be more comfortable during and after the procedure. Entering the surgical field via the nose, rather than through an incision in the mouth as in the previous Caldwell-Luc method, decreases risk of damaging nerves which innervate the teeth ...
Xray showing a sinus lift in the left upper jaw Sinus lift surgery, 3D Illustration. Maxillary sinus floor augmentation [1] (also termed as sinus lift, sinus graft, sinus augmentation, or sinus procedure) is a surgical procedure that aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian ...
Extension into the maxillary alveolar process may cause the roots of the molars and even premolars to lie just beneath the floor of the sinus or even project through the floor and into the sinus; in such cases, the roots of the teeth are typically surrounded by a thin layer of bone, but may sometimes lie directly underneath the mucous membrane ...
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
Cephalometric analysis depends on cephalometric radiography to study relationships between bony and soft tissue landmarks and can be used to diagnose facial growth abnormalities prior to treatment, in the middle of treatment to evaluate progress, or at the conclusion of treatment to ascertain that the goals of treatment have been met.

The frontal process of the maxilla is a strong plate, which projects upward, medialward, and backward from the maxilla, forming part of the lateral boundary of the nose. Its lateral surface is smooth, continuous with the anterior surface of the body, and gives attachment to the quadratus labii superioris , the orbicularis oculi , and the medial ...
