  • Title: [Experiences with the augmentation of vocal cords].
    Author: Berghaus A.
    Journal: HNO; 1987 Jun; 35(6):227-33. PubMed ID: 3305434.
    Abstract:
    Augmentation of a vocal fold serves to improve glottic closure and may be indicated for paresis of the recurrent nerve and after tumor resection. Methods include injection of viscous fluids (paraffin, liquid silicone, polyvinyl alcohol, gelatin, sesame oil, collagen and particularly teflon paste) and operations to tighten the vocal cord or displace it medially. The disadvantages of the former include the danger of overcorrection, tissue irritation and possible systemic absorption of the material. As an alternative, solid material such as cartilage or synthetics may be used for augmentation. Experience obtained so far has shown that chips of porous polyethylene (PHDPE) are particularly suitable: they are easy to use, show good tissue tolerance and are anchored by ingrowth of connective tissue. The value of photokymography of the larynx in the assessment of therapeutic results after vocal-fold augmentation is discussed.
