Abstract: To explore the value of multi-slice spiral CT post-processing technology in the diagnosis of sinus-nasal complex and sinusitis.112 patients with chronic sinusitis were selected as the subjects. The plane reconstruction of multi-slice spiral CT was used to observe the anatomical variation of the sinus-nasal complex and the inflammation of the sinuses. The results showed that the vesicular turbinate accounted for the largest proportion of the anatomical variation of the sinus ostium-nasal canal complex in 112 patients, reaching 30.36%, followed by nasal septum deviation (23.21%) and uncinate hypertrophy (13.39%). Among the 112 patients with nasal-sinus inflammation distribution, the anterior group had the largest proportion of ethmoid sinus, reaching 88.39%, followed by maxillary sinus ostia (69.64%) and maxillary sinus (66.07%). In 23 cases of functional endoscopic sinus surgery, the endoscopic findings of the lesions were consistent with the CT display. It is concluded that the use of multi-slice spiral CT post-processing technology has an important role in the anatomical structure and variation of the sinus-nasal tract complex in patients with sinusitis.
