Implantation of Porous Titanium Prosthesis in Laryngeal Surgery
Summary
This study evaluates a medialization implant to treat vocal cord paralysis, to permit it to adjust the quality of the voice under local or general anesthesia. The aim is to restore phonation using a porous titanium prosthesis in laryngeal surgery.

Medical and Biotech [MESH] Definitions
Dental Implantation, Endosseous
Insertion of an implant into the bone of the mandible or maxilla. The implant has an exposed head which protrudes through the mucosa and is a prosthodontic abutment.
Prosthesis Implantation
Surgical insertion of a prosthesis.
Dental Prosthesis, Implant-supported
A prosthesis that gains its support, stability, and retention from a substructure that is implanted under the soft tissues of the basal seat of the device and is in contact with bone. (From Boucher's Clinical Dental Terminology, 4th ed)
Maxillofacial Prosthesis Implantation
Surgical insertion of an appliance for the replacement of areas of the maxilla, mandible, and face. When only portions of the mandible are replaced, it is referred to as MANDIBULAR PROSTHESIS IMPLANTATION.
Ossicular Replacement
Surgical insertion of an implant to replace one or more of the ear ossicles.
