[Modified type I thyroplasty in the surgical treatment of unilateral laryngeal paralysis].
Subsequent to previous experience in the surgical treatment of vocal cord atrophy using various materials (Teflon, Hydron Gel, Gax Collagene) the authors treated severe glottic insufficiency using the Isshiki Type I Thyroplasty modified in terms of shape and thickness of the silicone prosthetic implant. This procedure provides several important advantages: it does not modify the mass, volume and stiffness of the operated vocal cord; it can be reversed or modified; it permits intraoperative control of the results. The first three cases operated with this technique are analyzed and videostroboscopic and electroacoustic evaluation are presented.
