Q

What is surgically removed in a typical total laryngectomy? CATTHINE

A

a. Cricoid and @ two tracheal rings (Where the larynx is attached to the trachea)
b. Arytenoids
c. Thyroid
d. True and false vocal cords
e. Hyoid
f. Intrinsic muscles of the larynx except cricopharyngeus
i. Cricopharyngeus
1. Surgeons usually try to save some of that muscles because that is where the prothesis will vibrate.
g. Neck dissection (maybe)
1. If there is evidence that the cancer has left the larynx and entered the lymph system. Leaves that side of the next really leather like and tough
h. Epiglottis

Q

How is the PE segment innervated in normals? In laryngectomees?

A

a. The area of the PE segment is innervated by one branch of the Superial Laryngaeal Nerve but most of it is innervated by the Recurrent Laryngeal Nerve
b. During a laryngectomee a portion of the superior laryngeal nerve is cut
c. The RLN does not get cut
d. Innervation to the PE segment is retained
* If it wasn’t the UES and LES would be hypertonic (floppy)

Q

What is a supraglottal laryngectomy? hemilaryngectomy?

A

a. Supraglottic laryngectomy
* Thyroid cartilage above ventricle
* Epiglottis
* Aryepiglottic fold
* Usually the hyoid bone

b. the surgeon removes part of the thyroid cartilage, including the underlying vocal cord or cords. This type is not done very often anymore as radiation is usually the first step of treatment for tumors on the vocal folds.

Q

Generally, what activities are precluded by laryngectomy and why?

A
  • Water activites
  • Because the stoma is a straight shot to the lungs
17
Q

Discuss some important points with regard to management of a tracheostomy tube.

A
  • Cleaning stoma tube
  • Cleaning stoma
  • Stoma covers
  • Sometimes the stoma will continuously try to heal so a stoma button is installed
  • Humidity
  • The air doesn’t get filter through a stoma so particles will just flow through
  • HME will filter and moisten the air.
18
Q

What advice would you give a laryngectomee about wearing a stoma cover/HME?

A
  • Sometimes the stoma will continuously try to heal so a stoma button is installed

Humidity
* The air doesn’t get filter through a stoma so particles will just flow through
* HME will filter and moisten the air.

19
Q

Describe the functions of the esophageal and cardiac sphincters.

A

d. Continuous with Pharynx at the Pharyngoesophageal (PE) segment
i. The junction of the pharynx and the esophagus is continuous

e. Upper Esophageal Sphincter (UES): Upper one inch of the esophagus
i. to prevent air from entering into the esophagus during breathing
ii. to prevent reflux of esophageal contents into the pharynx to guard airway aspiration

f. Thoracic Segment: Middle eight inches

g. Lower Esophageal Sphincter (LES) aka Cardiac Sphincter: Lower one inch
i. prevents the reflux of gastric contents back into the esophagus

20
Q

Is quality of life is better for patients treated with chemo-radiation versus surgery.

A

No, QOL is similiar

21
Q

Does the type of alaryngeal communication effect QOL?

A

Not according to most of the articles we discussed

22
Q

What is a Pearson “near-total” laryngectomy?

A
  • Tried to save one piece of the arytenoid so that it would move during phonation
  • Sometimes it worked and sometimes it did
  • Revisions were common because of no vibration
  • Still have a stoma
23
Q

What are the major advantages/disadvantages of conservation surgery?

A

Advantages
* Retain natural airway
* Because the larynx is essentially still there.
* May have a better voice than alaryngeal speaker
* Not necessarily
* Reduced impact on QOL

Disadvantages
* Lower cure rate, especially when lymph nodes are involved
* Because the surgeon is removing tissue based on what they can see – cancer cells cannot be seen so some cells may be left behind.
* Sampling of tissue on the margin of the tissue removed is done to check for cancerous cells and to see if more tissue needs to be removed
* Surgery for cancer has to remove all cancer cells to be successful.
* Dysphagia
* Lose protection mechanism for the airway.

24
Q

How is speech intelligibility related to quality of life after surgery for head/neck cancer?

A

Lower sentence intelligibility and word intelligibility scores were associated with diminished self-perceived QOL

25
Q

How does laryngectomy affect the senses of taste and smell?

A

a. Many patients complain of loss and smell
b. Sometimes it comes back and sometimes it does not

26
Q

What are the effects of radiation on alaryngeal communication?

A

a. Reduced loudness
b. Decreased quality
c. Decreased phonation time
d. Slower speech rate
e. Artificial larynx speech not necessarily effected especially with conduction tube
f. Recovery in about 60 days

27
Q

Do you think that laryngeal transplants will become commonplace? Why or Why not?

A

a. No
i. Age
ii. Etiology
iii. Immunosuppressive drugs
iv. Expense

28
Q

List the general problems associated with TE shunt/fistula.

A

a. Aspiration from leakage
b. Moving head may crimp shunt
* Because they’re made out of tissue
c. Shunt may change in dimensions
* Work initially but then stops working because of tissue changes
d. Requires use of one hand or valve

29
Q

What are 3 issues that laryngectomees report that affect quality of life?

A
  • difficulty expressing aspects of their character and personality
