22
Q

How long does Laser Laryngoscopy usually take?

A

30-40 minutes

23
Q

What are Pros of Laser Laryngoscopy?

3

A

More precise cut or excision

Less burn injury to surrounding tissue

Keeps the surgical field more free of obstruction

24
Q

What are Cons of Laser Laryngoscopy?

4

A

CO₂ laser can only be delivered to line of sight

Risk of thermal injury or scarring to adjacent
tissue

Risk of airway fire (O₂)

Increase in cost, personnel, and time

25
Q

What is the SLP’s Role in Surgery?

4

A

Educate about the need for voice rest

Educate about vocal hygiene and discuss ways of implementing this in patient’s daily life

Voice therapy after surgery as needed

Repeat videostroboscopy to show successive improvements

26
Q

What are the Surgical Intervention in Unilateral Vocal Ford Paralysis?

(2)

A

Injection

Thyroplasty (Implants)

27
Q

When can Injection be used to treat Unilateral Vocal Ford Paralysis?

(3)

A

Up to 1 year of initiating event

If there is no known permanent damage to RLN

If paralysis negatively affects voice and/or swallowing

28
Q

How is Office-Based Injection used to treat Unilateral Vocal Ford Paralysis?

(4)

A

Local anesthesia is used (via circothyroid membrane or orally)

Flexible laryngoscopy is used

Injectable material (usually Radiesse) is used to plump up the paralyzed cord

Helps paralyzed fold “meet” the other cord creating better glottic closure

29
Q

What are the PROS for treating Unilateral Vocal Ford Paralysis via Office-Based Injection?

(2)

A

Useful for poor surgical candidates

Gives immediate voice feedback

30
Q

What are the CONS for treating Unilateral Vocal Ford Paralysis via Office-Based Injection?

A

Patient discomfort

31
Q

How is Injection performed surgically to treat Unilateral Vocal Ford Paralysis in an Office?

(3)

A

Uses general anesthesia with direct visualization

Injectable material (usually Radiesse) is used to plump up the paralyzed cord

Helps paralyzed fold “meet” the other cord creating better glottic closure

32
Q

What are the PROS for treating Unilateral Vocal Ford Paralysis with Injection via Surgery?

(2)

A

Patient comfort

Precision of injection

33
Q

What are the CONS for treating Unilateral Vocal Ford Paralysis with Injection via Surgery?

A

No immediate feedback

34
Q

When can Thyroplasty (Implants) be used to treat Unilateral Vocal Ford Paralysis?

(2)

A

Past 1 year of initiating event

If permanent nerve damage has been determined

35
Q

Is treating Unilateral Vocal Ford Paralysis via Injection a permanent solution?

(2)

A

No.

It is temporary solution used during the “wait and see” period (can be up to a year)

36
Q

How is Thyroplasty (Implants) used to treat Unilateral Vocal Ford Paralysis in an Office?

(2)

A

Paralyzed cord is medialized by placing a silicone implant under the vocal fold muscle

Goal to “push the muscle” over to the midline creating better glottal closure

37
Q

Is treating Unilateral Vocal Ford Paralysis via Thyroplasty (Implants) a permanent option?

A

Yes

38
Q

How is Thyroplasty (Implant) used to treat Unilateral Vocal Ford Paralysis?

(6)

A

Thyroid cartilage is exposed, with the “key point” located

Outline instrument used to imprint the window for excision of cartilage

Window is cut and cartilage is removed

Measure window size again to carve out implant

Insert implant. Patient vocalizes to assess placement/ size for adequate glottic closure

Reassess implant size if needed

39
Q

What does treating Bilateral VF Paralysis surgically depend on?

(3)

A

How active patient is (exertion)

Timeline

Etiology

40
Q

What is the goal when treating Bilateral VF Paralysis?

A

Assuring the patients ability to breath

41
Q

What are surgical treatments used to treat Bilateral VF Paralysis?

(3)

A

Unilateral Transverse Cordotomy

Bilateral Transverse Cordotomy

Complete Cordectomy

42
Q

What is a Unilateral Transverse Cordotomy?

3

A

One vocal fold is divided from the vocal process

It is allowed to retract anteriorly

This allows for a larger posterior glottic gap (improve breathing) and anterior “bunching” (goal of maintain voicing)

43
Q

What is the goal in the Posterior Glottic Gap in Unilateral Transverse Cordotomy?

What is the goal in Anterior “Bunching”?

A

Improving breathing

Maintaining voicing

44
Q

What is a Bilateral Transverse Cordotomy?

2

A

Both vocal folds are divided from the vocal process

This allows for a greater glottal gap but leaves minimal risk for aspiration and minimal change in voice

45
Q

What is a Complete Cordectomy?

2

A

Complete removal of one vocal fold

This includes the vocalis muscle

46
Q

When is a Complete Cordectomy usually performed?

How is it performed typically?

A

To treat a localized malignancy

With laser laryngoscopy

47
Q

What are Isshiki four types of Phonosurgery Classification?

A

Type I

Type II

Type III

Type IV

48
Q

What is a Type I Phonosurgery Classification?

What is the goal?

A

Medialization Laryngoplasty

To bring VFs together

(Can be used with arytenoid adduction)

49
Q

What is a Type II Phonosurgery Classification?

What is the goal?

What does this change perceptually?

A

Lateralization laryngoplasty

To pull VFs apart

(Involves lateralization of thyroid cartilage)

Creates soft and breathy voice

50
Q

What is a Type III Phonosurgery Classification?

What is the goal?

What does this change perceptually?

A

Anterior-posterior thyroid cartilage shortening

To create a lax VF

Results in pitch lowering.

51
Q

What is a Type IV Phonosurgery Classification?

What is the goal?

What does this change perceptually?

A

Anterior-posterior elongation by crico thyroid approximation.

To create a longer, thinner VF

Results in higher pitched voice.

52
Q

Who is a Type IV Phonosurgery beneficial for?

2

A

Patients undergoing gender reassignment (feminization)

Patients with cricothyroid muscle paralysis
