Laser surgery is surgery that uses a beam of laser light, rather than other instruments, to cut, dissect, remove, and so forth. The beam of light has advantages over other cutting instruments, such as scalpel or scissors. First, at the same time that it cuts, it tends to seal off tiny blood vessels and reduce bleeding. Second, it may be especially useful in endoscopic surgery, where there is not a lot of room for instruments. Third, it is very precise. Both the microspot carbon dioxide laser and the RevoLix laser used at our practice have minimum spot sizes of about 1/5 of a millimeter.

Squamous cell carcinoma (1 of 6)

This man developed hoarseness across a few months. Biopsy elsewhere revealed squamous cell carcinoma, seen here on both vocal cords. Based upon a friend’s experience, he rejected radiotherapy, opting for laser resection, knowing it could be very hard on voice.

Laser Removal of Vocal Cord Cancer with Bilateral Disease

For treatment of early vocal cord cancer, both laser excision and radiotherapy are in competition as good treatment modalities. See also Early Vocal Cord Cancer: Remove with a Laser, or Radiate? Often, radiation is used when disease is bilateral, in the interest of preserving voice. This is an example of the ability to do fairly extensive laser surgery bilaterally, yet preserving good voice. This man had a friend who had severe difficulty with radiation, and he was therefore opposed to that option.

In contrast to what would be seen with a pulsed-KTP laser, one can see here hazy superficial coagulation affecting epithelium surrounding the vessels—so superficial that it will not affect vibratory flexibility.

Office-Based Surgery When General Anesthesia Is too Risky

Involuntary inspiratory voice (1 of 6)

This elderly man is tracheotomy-dependent due to inability to open the vocal cords. Here while breathing in, there is a posterior “keyhole” from the divots caused by pressure necrosis of the breathing tube. Still, due to inspiratory airstream, he produces involuntary inspiratory voice. General anesthesia for laser widening of the airway (posterior commissuroplasty) would be very risky due to his diabetes and many other medical problems. Hence, the decision to attempt this with patient awake and sitting in a chair.

Still, due to inspiratory airstream, he produces involuntary inspiratory voice. General anesthesia for laser widening of the airway (posterior commissuroplasty) would be very risky due to his diabetes and many other medical problems. Hence, the decision to attempt this with patient awake and sitting in a chair.

Laser posterior commissuroplasty (2 of 6)

The posterior right vocal cord is injected with lidocaine with epinephrine, in preparation for office laser posterior commissuroplasty. F = false vocal cord. T = true vocal cord, near its posterior end. The left vocal cord is injected similarly prior to the procedure that follows.

During the commissuroplasty (3 of 6)

The thulium laser fiber is being used to excavate the posterior commissure. Note the existing divot of the opposite (right) vocal cord (dotted lines) which will also be enlarged (next photos).

Deepening divot (4 of 6)

With view rotated clockwise approximately 45 degrees, work is commencing to deepen the right vocal cord divot.

Inspiratory indrawing decreased (5 of 6)

At the conclusion of the procedure. Not only is the ‘keyhole’ seen in photo 1 larger, but inspiratory indrawing of the rest of the vocal cords is greatly diminished.

Phonation (6 of 6)

Now phonating, voice is similar to the beginning of the procedure, because the vibrating part of the vocal cord was not disturbed. Of course, number of words per breath is slightly lower, due to increased use of air through the keyhole—air wasting.
