Surgical treatment of the laryngotracheal amyloidosis.

Two cases of primary localized amyloid tumor in the larynx and trachea surgically treated were herein reported. As recurrence of the amyloid tumor might lead to repeated resection in the same region, first trial of eradicative laryngofissure or laryngotracheofissure proved to be the effective approaches. The denuded area of the respiratory tract after removing amyloid tumor was covered with a split thickness skin graft and/or neighbouring mucosa applying soft rubber stent, then extensive scarring and schrinkage of the airways after surgery could thus be eliminated.
