Abstract

Purpose: The decision of whether to perform continuity-sparing or resecting surgery of the jaw in cases of malignant oral tumors is often difficult.

Patients and Methods: To aid in this decision, bone scintigraphy was evaluated retrospectively in 304 patients with a squamous cell carcinoma.

Results: One hundred forty-five patients showed no accumulation of the radionuclide, and none of them had infiltration by tumor histologically.

Conclusion: It was concluded that a bone-sparing resection of tumors close to the jaw may be justified when there is a negative bone scan.

    Hence, Tc-99m MDP SPECT can be a reliable adjunctive means of investigation in patients with malignancies with a tendency to invade the skull base or other possible bone pathologies affecting this area. In the surgical resection of oral cancers, surgeons have to decide very carefully whether to perform a procedure involving partial bone resection that preserves the mandible continuity or to sacrifice the mandible continuity (Fischer-Brandies and Seifert, 1995). In this situation, plain radiographs or CT scans have the disadvantage of giving sometimes false-negative results, since the initial stages of osseous invasion may not have caused sufficient loss of the mineral substance of the bone to be visible on radiography.
