Extrusion forces of resorbable tacks and titanium screws in laryngeal chondrosynthesis.

Laryngotracheal trauma, partial laryngectomy and phonosurgery may necessitate reconstruction of the cartilaginous skeleton to ensure the quality of respiration and voice. The present report focuses on initial experience gained with a new resorbable material for plates and tacks that allows chondrosynthesis of the laryngeal skeleton. A comparison of the extrusion forces necessary to pull out the resorbable tacks versus conventional titanium screws and the degree of deformation until failure represent the experimental parameters of reconstruction quality under investigation.
