Development of A Multi-section Olfactory Cleft Opacity Staging System in Patients With CCAD

This study aims to develop a modified CT scoring system to evaluate the association between olfactory cleft obstruction patterns and olfactory dysfunction in patients with central region atopic disease (CCAD). The main questions that the clinical trial aims to answer are: Can this modified CT scoring system be used to assess the degree of olfactory impairment in patients with CCAD? How well does the modified CT score correlate with the patient's olfaction compared to the traditional CT score?
