Which procedure involves the removal of mucosa from the maxillary sinus?

The procedure that involves the removal of mucosa from the maxillary sinus is the Caldwell-Luc operation. This surgical technique is often performed to address various conditions affecting the maxillary sinus, such as chronic sinusitis or to facilitate access for other surgeries.

During the Caldwell-Luc procedure, an incision is made in the canine fossa, allowing the surgeon to enter the maxillary sinus cavity. The mucosal lining of the sinus can then be carefully excised or removed. This technique not only helps in alleviating blockage and infection but also can be an approach to remove abnormal tissue or polyps.

In contrast, endoscopic sinus surgery primarily utilizes a nasal endoscope to visualize and operate on the sinuses, including the maxillary sinus, but does not specifically focus on mucosal removal in the same direct manner as the Caldwell-Luc. Nasal polypectomy targets the removal of nasal polyps, typically from the nasal cavity rather than from the maxillary sinus itself. Maxillectomy involves the removal of the maxilla or portions of it, which is a more extensive procedure compared to mucosal removal alone.
