Repetitive removal of cystic lining and scar tissues from the bone cavity accelerates new bone formation followed by peripheral osteotomy or resection of much smaller portions of bone as definitive treatment, thereby significantly reducing final morbidity. The aim is to reduce intracystic pressure via continuous drainage, so allowing newer growth centripetally from the bony walls. It comprises three entities-decompression, followed by repeated scraping of the lesion, and finally, peripheral ostectomy providing margin clearance but without significant morbidity. “Dredging” may be considered the “middle path” between conservative and radical treatment options. ![]() While there is no consensus on optimal treatment, complications and morbidity need to be avoided, particularly with large cysts. On the other hand, conservative options like marsupialization lead to the preservation of vital structures, but remnants of the epithelial lining may lead to recurrence requiring further surgical treatment. Radical treatment options for large cystic lesions such as segmental/marginal resection reduce the rate of recurrence but produce greater morbidity and deformity of the jaws. ![]() Treatment modalities of cystic lesions of the jaws range from conservative to radical.
