29
Q

What is the pathophysiology of a head and neck cancer patient?

A
reduced tongue/bolus control
reduced tongue elevation
slowed oral transit with disorganized tongue movement
delayed pharyngeal swallow
reduced tongue base retraction
reduced pharyngeal wall contraction
reduced laryngeal elevation
reduced UES/PES opening
reduced velopharyngeal closure
reduced epiglottic inversion
30
Q

What are the pathopysiologies of laryngeal cancer?

A

reduced laryngeal elevation
reduced glottal and laryngeal closure
reduced UES or PES opening
reduced pharyngeal wall contraction

31
Q

What are treatment options for head and neck cancer patients?

A

surgery - removal or resection?
radiotherapy or radiation- high energy rays used to kill cancer cells
chemotherapy- use drugs to kill cancer cells
combination of XRT and CT
clinical trials

32
Q

Describe treatment of surgery for small tumors from oral cancers.

A

small tumors on the tongue and mouth can occur and patient usually can have a resection utilizing healthy tissue on the floor of the mouth or the mandible.

33
Q

Describe treatment of surgery for large tumors from oral cancers.

A

Large tumors on tongue/mouth require larger resection

34
Q

What is a glossectomy?

A

partial or total removal of tongue

35
Q

When might they do radical neck?

A

if cancer is in the lymph nodeson one side

36
Q

Saliva glands are in the head and neck area. How many are in your neck?

A

200 of 700 are in your neck

37
Q

What happens in many resections?

A

there is not enough healthy tissue to complete closure of the surgery site so a flap or graft is done.

38
Q

What is a flap?

A

a piece of tissue that still has an artery attached to it transplanted to another part of the od.

39
Q

What is a graft?

A

a piece od tissue that….did not get the rest of this slide

40
Q

Where can tumors form in patients with laryngeal cancer?

A

supraglottic tumors form: epiglottis, false vocal folds, true vocal folds, aryepiglottic folds

41
Q

Unilateral laryngeal….

A

did not get enough information on this slide

42
Q

What kind of surgery happens on patients with laryngeal cancer?

A

supraglottic laryngectomy

43
Q

Describe a suprglottic laryngectomy.

A

Part or all of the hyoid bone and epiglottis superiorly, the aryepiglottic folds and the false vocal folds are removed.

44
Q

What is the biggest problem that happens because of a supraglottic laryngectomy?

A

getting tongue base to posterior pharyngeal wall to contact along airway with closure

45
Q

What happens when a patient gets a total laryngectomy for laryngeal cancer? TEST QUESTION

A

physical separation of the GI tract from the respiratory tract
OR
separation from the airway from esophogus
