Gliederung

Text

Objective: Bilateral vocal cord immobility (BVCI) may be treated by different endoscopic procedures. In this cadaver study three common methods (transverse chordotomy (TC), partial medial (MA) and total arytenoidectomy (A)) were compared to a newer suture lateralization method, the endoscopic arytenoid lateropexy (EAL).

Study design: The glottis enlarging efficacy of each procerure, the glottic area was assessed by a digital image analyzing program on 60 fresh cadaver larynges. In the first step, the reversible EAL was performed, then after the removal of the fixating sutures on 20 larynges transverse chordotomy, on 20 larynges total arytenoidectomy (TA) and on 20 larynges medial arytenoidectomy (MA) were performed.

Results: The glottic area: Cadaver position: 36,4 mm2, TC 61,0 mm2, MA 96,4 mm2, A 121,4 mm2, EAL: mean 134,4 mm2

Discussion: This objective results support the efficacy of EAL compared to A and TC, however in smaller larynx the arytenoidectomy provided slightly bigger glottis enlargement in some cases. Considering the reversibility and function preservation of EAL this method is suggested to be the primer treatment of these patients.
