Endoscopic Operations For Laryngeal Stenosis

Sources: A Manual Of Peroral Endoscopy And Laryngeal Surgery

Web formations may be

excised with sliding punch forceps, or if the web is due to

contraction only, incision of the true band may allow its retraction.

In some instances liberation of adhesions will favor the formation of

adventitious vocal cords. A sharp anterior commissure is a large

factor in good phonation.

Endoscopic evisceration of the larynx will cure a few cases of

laryngeal cicatricial stenosis, and should be tried before resorting

to laryngostomy. A sliding punch forceps is used to remove all the

tissue in the larynx out to the perichondrium, but care should be

taken in cicatricial cases to avoid removing any part of either

arytenoid cartilage. In cases of posticus paralysis the excision may

include portions of the vocal processes of the arytenoids.

Ventriculocordectomy is preferable to evisceration. The ventricular

floor is removed with punch forceps (Fig. 33) first on one side, then

after two months, on the other.
