A cyst is a pathological cavity that may be filled with semi-solid, liquid or gaseous
substances. A non- malignant tumour is any pathologic swelling that is solid in nature. Cysts
and tumours in the orofacial region may be of dental or non-dental origin. They cause pain,
discomfort and swelling, and impair normal function.
These lesions are usually benign, but few may also progress to cause malignancy. Hence it is best to undergo biopsy and arrive at a correct diagnosis of the lesion. Once diagnosed as a non-malignant cyst or tumour, the treatment usually involves excision of the lesion and ensuring that the surrounding tissues are free of pathologic tissue. In case of large defects, reconstruction may be required.
