Throughout the aerodigestive tract

What role do you salivary glands play?

Digestion and tooth protection

What is the largest salivary gland?

The parotid gland

Which gland is located superficial and partly behind the Remus of the mandible covering the masseter muscle and largely fills the space anterior to the sternocleido muscle

Parotid

What duct does the parotid gland drain to?

What is the smallest Major gland

Sublingual

Which gland lies between the mucous membrane of the four of the mouth above the Mylohyoid muscle below the mandible laterally

Sublingual

Which gland fills the triangle between the two bellies of the digastric and lower border of the mandible and extends upward deeply to the mandible

Submandibular

What are some etiologic factors Of salivary gland, tumors

Atomic bomb survivors, early radiation, exposure, dental radiographs, cigarette smoking, low intake of vitamin A, and C, hardwood dust

What is the most common presentation of salivary gland of tumors?

Painless enlarging mass in the mass can last up to 4 to 8 months before becoming noticed

Facial palsy and swelling can be a common sign of

A salivary gland tumor

What are the most common histories of salivary gland tumors

Acinic cell carcinoma, mucoepidermoid carcinoma, adenocarcinoma, pleomorphic Adenoma

What is the most common benign salivary gland tumor histology?

Pleomorphic adenoma

What is the most common malignant tumor in the major salivary glands?

mucoepidermoid carcinoma

The most common malignant tumor that arises in the minor salivary glands is

Adenoid cystic carcinoma

The most common site for adenoid cystic carcinoma of the minor salivary glands is

Palate

Acinic carcinoma usually occurs in

Parotid gland

Which salivary gland has the highest sight of incidence

parotid

are most salivary gland, tumors of benign or malignant

Benign

True or false female patients of the history of carcinoma of the major salivary glands has an incident rate for breast cancer that is eight times higher than the healthy population

True

Malignant neoplasm for the salivary glands occur in patients with an average age of blank and benign tumors occur at around what age

55, 40

What is the male to female ratio for salivary gland tumors

It is equal

What percentage of minor salivary gland tumors are malignant

88%

What does the workout consist of for salivary glands?

H and P With attention to sign signs of local fixation, adenopathy, and nerve involvement

CT for the extent of lesions in the parotid

MRI for detecting perineural invasion

Find needle biopsy

What is the preferred biopsy method for salivary glands?

Find needle biopsy because incisional or excisional biopsies risk injury to the facial nerve and have surgical morbility

What is the general management for salivary gland tumors

Surgical excisions with postop RT for high risk features

Notes within the gland and the majority are located in the superficial lobe

Retroauricular upper cervical stensons duct

Lymph node involvement is most commonly involved with which gland

Submandibular

Which salivary gland histology has the lowest frequency of cervical node involvement, but per neural invasion is common

adenoid cystic carcinoma

Staging for the salivary glands is based on

Size and extraparenchymal extension

What are some prognostic factors of salivary gland tumors

Survival is influenced by tumor type grade post surgical residual disease, tumor size nerve invasion

Salivary gland staging T1-4

T1- <2

T2- >2 <4

T3- >4 and extension

T4- advanced
