INCIDENCE OF MUCOUS RETENTION CYST IN MAXILLARY SINUS; A RETROSPECTIVE RADIOGRAPHIC STUDY

Abstract

Mucous retention cysts (MRC) are benign, self-limiting lesions that originate from the accumulation of fluids inside the sinus membrane. MRC are incidental radiological findings and may appear as a round, dome-shaped, relatively radiopaque lesion originating from the wall of the paranasal sinus. Very few studies have investigated the incidence of MRCs in the maxillary sinuses. The present retrospective study evaluated the incidence of MRCs in maxillary sinus.

Results and Conclusion: The prevalence of MRCs was observed to be 2.o3 % (61 cases). The mean age of the patients was 35.6 years, and the male: female ratio was 2.5:1. Further studies should be conducted to assess the MRCs location and size in other paranasal sinuses using CT imaging modalities.
