Hydroxylapatite for Laryngotracheal Framework Reconstruction

Abstract

Hydroxylapatite plates and rings were employed for reconstruction of the laryngotracheal framework in 12 patients. The cause of the framework defect was surgery for stenosis in nine cases and removal of malignancy in the other three. The trough method associated with a two-stage procedure was tolerated in all 12 cases. Hydroxylapatite plates or rings were used to reconstruct the framework during the second stage. The implant was well taken in all cases, without any infection or rejection. Nine of the 12 cases resulted in excellent airways.

Repair and Regeneration of the Respiratory System: Complexity, Plasticity, and Mechanisms of Lung Stem Cell Function

“…Synthetic scaffolds have also been explored for use as tracheal replacements. Clinical trials of solid prostheses have included materials such as stainless steel (Cotton et al, 1952), steel coil (Beattie et al, 1956), silicone (Neville et al, 1990), polyethylene (Clagett et al, 1952), Teflon (Ekestrom and Carlens, 1959), and hydroxylapatite (Hirano et al, 1989). However, most solid prostheses eventually fail to become well integrated with the surrounding tissue and cause problems with infection, dislodgement, migration, and obstruction with granulation tissue (Grillo, 2002).…”

Reconstruction of the Anterior Laryngeal Wall with a Composite Graft of Demineralized Bovine Bone Matrix and Autogenous Perichondrium

“…1993 alloplastic material have been reviewed by Bailey and Kosoy [8] and Jacobs [9]. For the reconstruction of the cricoid, hydroxylapatite wrapped in autogenous tissue proved to be the most suitable graft as it is fully incorpo rated in the cartilaginous cricoid ring [10,11]. However, the use of hydroxylapatite should be restricted to the adult stage.…”
