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.
