This digital library houses the book on Oncology and Orthopedic Oncosurgery.

It includes academic lectures, presentations from national and international congresses, published papers, case discussions, performed surgical procedures, and proprietary techniques developed.

The digital format was chosen because the web allows the inclusion of texts with numerous visual resources, such as images and videos, which would not be possible in a printed book.

The content is intended for students, healthcare professionals, and the general public interested in the field.

Skull Osteoma Resection Technique. Female patient, 48 years old, with a tumor on her forehead for three years. She reports a slow and progressive, painless appearance, which only makes aesthetics more difficult. She has not seen growth in the last year. Nodular, hard lesion, attached to deep planes, approximately three centimeters in diameter. Figures 1, 2 and 3 illustrate the clinical aspect of the lesion and figures 4 and 5 show the radiographic aspect of the image.

To better document these images, we performed a computed tomography (Figures 6,7,8 and 9).

Analysis of the history, clinical picture and images of a homogeneous, compact lesion, with precise limits, producing mature bone, allowed the diagnosis of osteoma, with resection of this lesion for aesthetic reasons. The surgery was performed under general anesthesia and local infiltration to reduce bleeding (figures 10 to 20).

Ostectomy with electric saw

The electric saw did not prove to be the most suitable instrument for performing ostectomy and regularization, as we can see. This was best done with the chisel (figure 17).
