Osteosarcoma of the skull is a common benign tumor characterized by slow growth, painlessness, and unclear borders with the surrounding skull. Can occur in any part of the skull, with the frontal and parietal more common, other skull and skull base bone less common. Osteomas are usually single, but there are multiple or polystimulation in one place. Some patients may also have tumors in other parts of the body.
Symptoms and signs
Due to the slow growth of tumors, they are easily overlooked in the early stages and the course of disease may be longer. Some may stop growing on their own. Most osteomas are located at the cranial apex. They are mostly seen in plate types. They are rounded or conical bulges protruding from the cranial apex outer plate. They range in size from several millimeters to several centimeters in diameter, and do not adhere to the scalp or tenderness. There is no discomfort to the scalp. Sense, in addition to causing appearance deformation, generally does not cause special symptoms. Barrier type mostly expansive growth, a wider range, more prominent cranial bulge, can appear local pain in the corresponding parts, the inner plate type multi-directional intracranial growth, rare in clinical practice.
The treatment of osteoma is based on surgery. Craniotomy requires a precision instrument craniotomy, which can use a single craniotomy drill or a multi-function drill data system. The cranial aneurysm may not be treated if it has small size and no specific symptoms or if the individual has stopped growing. Fast-growing, affecting face and symptomatic osteoma should be removed surgically. For bone tumors limited to the outer plate, only flattening or smoothing is required, and the remaining substrate does not need to be inactivated by electrocautery. Large bone involvement involving intracranial osteoma requires bone flap resection. The bone-bearing flap is inactivated by boiling for 30 minutes, and is then placed back after plastic treatment. Osteosarcoma involving the paranasal sinus should be surgically removed if it has caused paranasal sinus occlusion. The frontal sinus osteoma is treated by subfrontal epidural approach. The ethmoid sinus osteoma can be removed via a fistula or via a palatal approach. Thoracic osteoma needs total resection to avoid recurrence.
