Sinus coronal ct examination from front to back to observe the maxillary sinus, sieve sinus, frontal sinus, pterygoid sinus and other sinus morphology and structural changes, including sinusitis, deviated septum, nasal cavity and sinus tumor and other diseases.
1. Sinus coronal ct, is the more commonly used clinical examination of the nasal cavity sinus method, mainly from front to back to show the nasal cavity, sinuses and surrounding structures up and down the left and right relationship, can show the attachment of hooks, the morphology of the middle and lower turbinate, and show the morphology of multiple sinuses and nasal sinuses and nasal sinus complex, the designation of the surgical program has an important guiding significance.
2. Sinusitis in ct can be manifested as mucosal thickening, fluid accumulation in the sinus cavity, and in severe cases, soft tissue shadow will be produced in the sinus cavity.
3. Nasal septum deviation, in ct shows that the nasal septum bone was C type, S type or spine and other types of protrusion, on the nasal cavity of the surrounding structures to produce the phenomenon of extrusion.
4. Nasal cavity or sinus tumors on CT show that there are soft tissue shadows in the nasal cavity or sinus, and the surrounding bone is damaged, and there will be enhancement after scanning with enhancers.
Sinus CT is divided into coronal, horizontal and sagittal positions, and the combination of the three positions can analyze the sinus situation more comprehensively and make a more comprehensive diagnosis.
