Abstract:
Cysts of the oral cavity are among the most commonly encountered biopsy specimen in histopathology. Shear categorized the cysts associated with maxillary antrum under four subheadings - mucocoele, retention cyst, pseudocyst, and postoperative maxillary cyst (PMC). PMC is also known as surgical ciliated cyst, postoperative paranasal cyst, or respiratory implantation cyst. Although it constitutes 20% of oral cysts in Japan, it is quite rare in the other parts of the world. Herewith, we report a case of a 65-year-old female who presented with the complaint of palatal swelling and having a history of maxillary sinus surgery 30 years ago.
