Mucous Retention cyst is a mass of fluid containing serous or mucous. Nasal septum deviation (NSD) is a condition that may cause sinusitis in severe cases. In addition, the frequency of maxillary sinus retention cysts is higher in patients with sinusitis than in patients without sinusitis. This study aimed to evaluate the retention cyst in the paranasal sinuses in patients with septum deviation compared with those without NSD. This observational study was performed by simple random sampling from CBCT scans of patients over 18 years’ old those referred to the radiology department of Isfahan Dental School (Khorasgan) 100 patients with NSD and 100 patients with no NSD. Data were analyzed by independent samples t-test, Mann-Whitney U test, Chi-square, and Fisher exact tests. Mucous retention cysts were observed in 5% of patients without NSD and 19% of patients with NSD (p = 0.002). Also, the number of cyst retention was significantly higher in patients with NSD (p = 0.002) but there was no significant relationship between cyst side and nasal deviation in patients with NSD (p = 1.00). There was a significant relationship between the occurrence of mucous retention cysts and NSD and the number of cysts in the group with greater deviation.
