This study aims to describe pathologic fractures of the jaws due to cystic bone lesions. Their daily clinical practice findings are not very common, so their treatment can be challenging. In addition, endosseous benign lesions like a radicular, residual, solitary, aneurysmal cyst, and odontogenic keratocyst, might weaken the bone so that trauma, or usual chewing, could break it. We follow from the first clinical examination to the X-ray or CBCT examination and surgical management of our patients, reporting all procedures and results to explain our approach to these cases. We also reviewed the literature briefly to determine if our operative management is in line with the scientific community. Mandibular angle and body are common locations, while symphysis and condyle are less so. Young men are the most affected, and trauma is the most triggering event. Cyst enucleation, followed by fracture reduction and fixation, is the treatment of choice for our clinical team and the scientific community. We observe how impactful it is to approach the cavity of the cystic lesion from the fracture line as the surgical gold standard.
