Capillary ectasia is the enlargement or dilation of capillaries on the surface of the vocal cords. Some believe it to be an estrogen effect similar to “spider veins” that one might see on the legs, for example. At our practice we think of these as mainly being another manifestation of overuse of the voice, and a response to ongoing injury of the vocal cords.
Once established, it may cause symptoms of reduced vocal endurance and exaggerated premenstrual huskiness. Capillary ectasia may also increase the risk of vocal cord bruising (hemorrhage) and hemorrhagic polyp formation. Many affected individuals, however, may “coexist” with this when armed with appropriate information about this disorder and through carefully managing amount and manner of voice use. When indicated, it is easily corrected via vocal cord microsurgery.
Photos of capillary ectasia:
Capillary ectasia (1 of 7)
Abducted, breathing position, standard light. This is a vascular abnormality and not a polyp. We use the term “capillary lake.”
Capillary ectasia (3 of 7)
Strobe light, open phase of vibration. Mucus is consistent with the patient’s known acid reflux laryngitis.
Capillary ectasia, after laser coagulation (5 of 7)
Abducted breathing position, standard light, some weeks after pulsed-KTP laser coagulation of the dilated capillaries, which are no longer visible.
Capillary ectasia and hemorrhagic polyp, after treatment (3 of 4)
Abducted breathing position after vocal cord microsurgery, standard light. Note that the right cord is normalized, the capillary ectasia on the left is smaller, but persists in spite of spot-coagulation. A simple pulsed-KTP laser procedure in the videoendoscopy procedure room abolished this residual lesion.
Capillary ectasia with vocal nodules (1 of 2)
Breathing position, note insignificant micro-web at anterior commissure.
Capillary ectasia with vocal nodules (1 of 3)
Standard light reveals dilated capillaries, especially left vocal cord (right of image), as well as bilateral vocal nodules.
Capillary ectasia with vocal nodules (2 of 3)
Narrow-band light makes the dilated capillaries stand out more clearly.
Capillary ectasia (1 of 3)
Bilateral capillary ectasia, made to stand out with the help of narrow-band illumination.
Capillary ectasia, right after laser coagulation (2 of 3)
At the conclusion of pulsed-KTP laser coagulation, performed in a videoendoscopy procedure room with patient awake and sitting in a chair.
Capillary ectasia and hemorrhagic polyp (1 of 2)
Note the differing patterns of capillary ectasia—fine “stream;” meandering “river,” and “pond.” Brilliant white areas are reflection of light; more indistinct submucosal white area right cord raises question of possible cyst (arrow).
Vocal nodules, leukoplakia, and capillary ectasia (1 of 4)
Abducted breathing position, standard light. Notice not only the margin swellings (nodules) but also the ectatic capillaries and the roughened leukoplakia. This person illustrates well the idea that vibratory injury can be manifested differently. Many express the injury more in the form of sub-epithelial edema and other changes; this person also has considerable epithelial change.
Vocal nodules, leukoplakia, and capillary ectasia: 6 months later (3 of 4)
Partial resolution of mucosal injury as a result of behavioral changes directed by a speech pathologist. Strobe light, open phase of vibration.
Capillary ectasia and hemorrhagic polyp (1 of 7)
Open position for breathing, standard light. There is capillary ectasia on both vocal cords, and there is also a hemorrhagic polyp of the left vocal cord margin (right of photo).
Capillary ectasia and hemorrhagic polyp (2 of 7)
During voicing, the polyp interferes with accurate approximation of the vocal cords, which explains this man's chronic hoarseness.
Capillary ectasia and hemorrhagic polyp, thulium laser treatment (3 of 7)
Using the thulium laser to spot-coagulate and interrupt the flow in dilated capillaries.
Capillary ectasia and hemorrhagic polyp, thulium laser treatment (4 of 7)
Coagulation of the polyp, with fiber tangential to the vocal cord and sometimes lifting medially during contact mode. A second, similar procedure was needed a few weeks later, only for residual polyp.
Capillary ectasia and hemorrhagic polyp, after treatment (5 of 7)
Several weeks later, capillary areas are blanched, but the vocal cord mucosa is fully mobile.
Capillary ectasia and hemorrhagic polyp, after treatment (6 of 7)
Vocal cord margin match and mucosal flexibility are best tested in high voice. This is strobe light, closed phase of vibration, at F4 (~349 Hz).
Capillary lake (1 of 6)
This teacher struggles with reduced mucosal endurance: the sense of slight laryngitis after extensive talking. This is likely due to the increased mucosal vulnerability to either swelling or hemorrhage caused by this capillary lake. This is a stable finding, whereas a hemorrhage resolves at least intermittently over time. Note that there was a recent surgical procedure performed elsewhere on the left cord (right of photo); the nature of the prior lesion is unknown to the patient.
Mucosal fatigue (2 of 6)
At D4 (294 Hz) under strobe light, the capillary lake and bilateral translucent swelling is seen, verifying in another way that “mucosal fatigue” is the likely cause of his reduced vocal endurance.
Prep for laser coagulation (3 of 6)
The same capillary lake seen with the smaller-chip channel scope, in preparation for pulsed-KTP laser coagulation. Note the red color and compare with post-KTP images that follow.
KTP laser coagulation (4 of 6)
The glass fiber is delivering KTP laser energy that is preferentially coagulating the red hemoglobin.
Post laser ablation (5 of 6)
Immediately after laser ablation, the red lake has changed color due to denaturation/ coagulation.
Post laser ablation, distant view (6 of 6)
More distant view after ablation is complete. Compare with photos 1 and 3.
After a weekend of vocal overuse (7 of 8)
Several months later, after a brutal weekend of coaching. Strobe view, closed phase of vibration. No evidence of residual ectasia that had been causing such reduced ability of the mucosa to “endure” vibratory trauma. Note the margin swellings and slight pinkness from vibratory trauma.
Hoarse choral singer (1 of 4)
Older amateur but experienced and committed choral singer is grossly hoarse due to this chronic vascular lesion, left vocal cord (right of photo).
2 months post-surgery (3 of 4)
Nearly 2 months after surgery, only a bit of ectasia (non-threatening as it is upper surface e of the cord) is seen. The patient says voice is fully restored.
Red Herring Capillary Ectasia and Mucosal Injuries
Obvious mucosal injury (1 of 3)
This young woman is hoarse, but two examinations elsewhere returned no significant findings. Her upper voice limitations during vocal capability testing already tell us “for certain” that there is mucosal injury, even before we look at the larynx. In this mid-range view, we can see early contact at the mid-cords, but the full extent and nature of the injuries are seen in the closer views that follow.
Vocal nodules (2 of 3)
At a more appropriate level of magnification, the vocal nodules are seen. But we want to know more…
Margin swelling and bruising (1 of 2)
This professional woman is extraordinarily dynamic and intense, and must talk all day to do her work. Here, the right vocal cord (left of photo) is bruised due to vibratory trauma. The margin swelling on the right causes her hoarseness more than the bruising, however.
Six weeks later (2 of 2)
Six weeks later, the bruise is mostly resolved. The capillary that “leaked” blood to form the bruise is now seen more clearly (long arrow). This ectatic capillary can be seen easily now when looking back at photo 1. The short arrows indicate the residual “smudges” of discoloration caused by breakdown products of the bruise. The last evidence of widespread vocal cord bruising is always in these two locations.
(1 of 7)
In this musical theater singer, under narrow band (blue-green) light, we see an ectatic (dilated) capillary leading to a small hemorrhagic polyp on the left vocal cord (right of photo).
(2 of 7)
Now under strobe light, at E5 (660 Hz), there is also a projecting component that interferes with margin approximation.
(3 of 7)
Just prior to pulsed-KTP ablation, again under narrow band light. The arrows point out the feeding capillary, for comparison with photo 5.
(4 of 7)
Under standard light, the glass fiber is seen. The "white" spot is only the aiming beam; no laser energy is being delivered at this moment.
(5 of 7)
At the conclusion of the laser procedure. You can see that not only is the blood in the polyp coagulated but the flow of blood in the feeding capillary has also been (note discontinuity at the arrows, where the capillary has "disappeared." Compare with photo 3.)
(6 of 7)
Three weeks later, voice is restored to "original equipment" capabilities. The area of treatment (surrounded by tiny dots) is arguably "blanched" with fewer capillaries in general, but with no loss of mucosal flexibility under strobe light. Compare with Photo 1.
