1. PRINCIPLES OF SURGICAL MANAGEMENT
OF JAW TUMORS

2. many tumors behave similarly and therefore can
be treated in a similar manner The three main
modalities of surgical excision of jaw tumors are
(1)enucleation (with or without curettage),
(2) marginal (i.e.,segmental) or partial resection,
(3) composite resection
Many benign tumors behave nonaggressively and
are therefore treated conservatively with
enucleation, curettage, or both

4. Aggressiveness of Lesion
Surgical therapy of oral lesions ranges from
enucleation or curettage to composite resection.
Histologic diagnosis positively identifies and
therefore directs the treatment of the lesion.
Because of the wide range in behavior of oral
lesions, the prognosis is related more to the
histologic diagnosis, which indicates the biologic
behavior of the lesion, than to any other
single factor.

5. Those factor are
• Anatomic Location of Lesion
• Duration of Lesion
• Reconstructive Efforts

6. Jaw TumorsTreated
• with Enucleation, Curettage, or Both
unlike that described for cysts. However, additional procedures,
such as sectioning large calcified masses with burs in odontomas
and cementomas, may be required
• with Marginal or PartialResection
When the lesion is known to be aggressive, by histopathologic
determination or by its clinical behavior, or it is of such a consistency
that total removal by enucleation, curettage, or both would be
difficult, removal may be facilitated by resecting the lesion with
adequate bony margins.

9. MALIGNANT TUMORS OF THE ORAL
CAVITY
• Malignancies of the oral cavity may arise from a variety of
tissues, such as salivary gland, muscle, and blood vessels, or
may even present as metastases from distant sites.
• Clinical staging refers to assessing the extent of the disease
before undertaking treatment and has as two purposes:
(1)selection of the best treatment
(2) meaningful comparisonof the end results reponed from different
sources

10. Treatment Modalities for
Malignancies
• Radiotherapy
• Chemotherapy
• Surgery
