To confirm the presence of submandibular gland ductal obstruction, X-ray or imaging can be used, as well as direct endoscopic observation.
1. When there is a suspicion of submandibular gland ductal obstruction, X-ray examination or imaging can be used.
X-ray examination can directly observe the patency of the submandibular gland duct and help determine the presence of inflammation, stones and other diseases. Ductography can directly observe the direction of the contrast agent in the duct by injecting the contrast agent, so as to directly determine whether there are symptoms of ductal obstruction.
2. In addition to imaging, endoscopy can also help to confirm the presence of submandibular gland ductal obstruction.
Endoscopy is a minor surgical procedure that involves placing a viewing probe into the duct to directly visualize the smoothness of the duct and the health of the duct wall and other tissues. Endoscopy may cause minor damage or irritation to the catheter tissue and should be performed with caution.
In case of catheter obstruction or other related diseases, it is recommended to choose the appropriate examination method under the guidance of a doctor.
