La Laryngite

La laryngite est une infection ou une inflammation du larynx. La cause peut être virale, bactérienne ou fongique (candida). Ou cela peut résulter d’un reflux acide, d’une radiothérapie anticancéreuse, d’une intervention chirurgicale (comme inflammation postopératoire temporaire) ou d’une maladie auto-immune.

Chronic Bacterial Laryngitis

La laryngite bactérienne chronique est un problème laryngologique à la recherche d’une solution plus définitive. Vu chez les personnes qui ont subi une radiothérapie ou qui ont un déficit immunitaire. La laryngite peut souvent être améliorée avec des antibiotiques, mais se reproduit souvent lorsque les antibiotiques sont arrêtés. Parfois, l’administration chronique d’antibiotiques est nécessaire. Ou, irrigations laryngées.

whitish discoloration on the left vocal cord — Candida laryngitis (1 of 3)

Elderly woman with a history of laryngeal amyloidosis requiring laser sculpting several years earlier. Now using high-dose inhaled steroids, antibiotics, and oral steroids for unrelated pulmonary problem. Marked increase of hoarseness, and whitish discoloration, especially of the left vocal cord (right of image).

hazy white areas and irregular right cord margin — Candida laryngitis (2 of 3)

Closer view of hazy white areas and irregular right cord margin (left of image), presumed to be candida overgrowth. Empiric treatment with fluconazole is justified, given history and findings.

white areas are completely resolved — Candida laryngitis, after starting treatment (3 of 3)

Two weeks after starting fluconazole; the white areas are completely resolved. The patient’s voice had improved markedly within three or four days of starting the treatment.

Guérison progressive de la laryngite ulcéreuse

Ulcerative laryngitis — Ulcerative laryngitis (1 of 4)

Ulcerated area, free margin of both vocal cords. When diagnosed at this early stage, the patient is notified that recovery will likely require as much as six weeks.

Ulcerative laryngitis — Ulcerative laryngitis (2 of 4)

Same view, but using narrow band illumination to accentuate the ulcers.

1 month later: ulcerative laryngitis healing — 1 month later: ulcerative laryngitis healing (3 of 4)

One month later, under narrow band illumination. Ulceration dramatically diminished.

3 months later: ulcerative laryngitis virtually all healed — 3 months later: ulcerative laryngitis virtually all healed (4 of 4)

At three months, standard illumination. Virtually complete healing, with excellent return of voice. The prominent vascularity at area of ulcer will eventually fade.

Ulcère des cordes vocales

Vocal cord ulcer — Vocal cord ulcer (1 of 2)

In a patient who had had hoarseness lasting several months, this inflammatory lesion of the right vocal cord (left of image) was identified. There is hazy leukoplakia surrounding a central intensely erythematous ulcer. It most resembles an aphthous ulcer, though these are not previously reported on the vocal cord, and this lesion’s duration is longer than the typical aphthous ulcer.

Vocal cord ulcer — Vocal cord ulcer (2 of 2)

Closer view, under narrow-band light. The vessel pattern looks inflammatory and not neoplastic. There is heaped-up leukoplakia surrounding the lesion. After this lesion persisted for more than four months, it was removed. Tissue examination showed inflammatory response and keratosis without atypia.

Laryngite sèche

Laryngitis sicca: crusting of dry, green mucus on vocal cords — Laryngitis sicca (1 of 2)

Laryngitis sicca, with crusting of dry, green mucus especially undersurface of the folds. Though a rare long-term complication, may be seen after laryngeal irradiation for cancer (Lab).

Adducted (voicing) position with Pachyderma — Pachyderma (2 of 3)

Adducted (voicing) position. Note that the pachyderma does not interfere with closure of the cords. In this case, it does not directly affect the patient’s voice, which is typical, but the more generalized inflammatory condition (see the redness of the cords) does.

Laryngite aiguë « rougeur »

A normal larynx — A normal larynx (1 of 4)

This larynx is seen here in its normal state of health. Study the vascular markings and color at locations marked “1” (right false vocal cord) and “2” (anterior subglottis). We see a normal capillary pattern with relatively “white” areas between.
