Digestion and Tooth protection
What is the larget of the salivary glands?
Parotid
Where is the parotid located behind?
ramus of mandible
Tumors of the parotid gland are mostly benign. True or False?
True
Hematogenous Mets are uncommon. True or False?
False
Which gland has the highest incident rate of the salivary glands?
Parotid
What percentage of parotid incidences are benign?
2/3
What percentage of occurrence of paranasal diseases are found in the submandibular?
10%
Most submandibular diseases are benign. True or False?
False, they are malignant
What are some risk factors for submandibular disease?
Dental radiographs, Other radiation procedures, and hardwood dust
What are the 4 types of salivary gland disease?
Adenoid Cyst, Mucoepidermoid, Adenocarcinoma, and Squamous Cell
Most salivary glands are benign tumors. True or False?
True
in terms of surgical treatment, how are salivary glands treated?
Total resection with large margins to spare facial nerve
in terms of radiation therapy, how are salivary glands treated?
Post-op for residual, Recurrent disease, inoperable lesions and disease w/ extensive nerve involvement, perineural involvement of the facial, trigeminal, hypoglossal, and lingual
What is the XRT dose for high risk? Low risk? Intermediate risk?
66-70 Gy for high risk and 44-50 Gy for low risk and 54-63 for intermediate-risk
What is the XRT dose for post-op treatment? (high, Intermediate and low risk)
66-60 Gy for high risk (+ margins) and same for low and intermediate risk
The radiation technique for salivary glands is designed for what?
to fit local invasion and lymphatic spread, wedged pair, and bolus over spread
In terms of patient orientation, what can be done in terms of treating for salivary gland?
Patient can be positioned on side with lateral side of the head facing upwards
What is the treatment technique orientation utilized for cancers of the salivary gland?
Wedged pair, superior and inferior oblique fields
What is the significance of the oblique fields for salivary gland rt tx?
the obliques direct the beam away from the oral cavity and orbits, requires a table rotation of 90
When using anterior and posterior obliques for Salivary gland treatment, what should be considered?
Must consider contralateral orbit during treatment
