Abstract Objective: To study the correlation between the anatomic variations of the ostiomeatal complex(OMC) and sinusitis through the observations by multi-slice spiral CT(MSCT). Methods: 291 subjects who were examined with MSCT in our hospital were randomly selected in this study. The anatomic variations of the OMC were observed and recorded. Statistical analysis was done by Chi-square test with SPSS 15.0. Then, occurrence in the non-sinusitis and the sinusitis group was compared. Result: The OMC’s structure, variations and lesion could be clearly shown by the bone reconstruction and multiplannar reconstruction. The variation rate of sinusitis group was higher than non-sinusitis group. There is significant difference between the sinusitis group and non-sinusitis group with the movement and curl of uncinate, hyperpneumatization of agger cells and ethmoidalis(P＜0.05). Conclusion: The OMC’s structure, variations and lesions can be clearly observed by using multiplannar reformation techniques of MSCT. There is an intimate relationship between the anatomic variations of OMC(movement and curl of uncinate, hyperpenumatization of agger cells and ethmoidalis) and the morbidity of sinusitis.
