- Various surgical techniques have been proposed for
the management of patients with bilateral vocal fold paralysis
(VFP) or posterior glottic stenosis (PGS), which
make use of external and endoscopic approaches. The
purpose of these surgical treatments is to restore an adequate
airway without disturbing voice quality and swallowing.
It has been known that medial arytenoidectomy and
cordotomy using laser, which partially resects the medial
portion of the arytenoids, can preserve the airway and voice
quality without damage on the membranous vocal fold.1
However, laser arytenoidectomy and cordotomy may result
in granulation or scar tissue formation after surgery,
which could fail to restore the adequate airway.
Submucous medial arytenoidectomy can prevent granulation
tissue formation, thus accelerating healing processes
and improving treatment outcomes. We herein
describe our experiences in the management of bilateral
VFP and PGS by combining posterior transverse partial
cordotomy, as described by Dennis and Kashima,2 with
modified method of submucosal medial arytenoidectomy,
as described by Crumley.
