Experience has shown that it is much easier to correct a hoarseness from laryngeal paralysis than from cordectomy or traumatic vocal cord injury. This is so because the defective cord has so little substance to retain the injected material and very often insufficient pressure can be applied to separate the scarred remnant of the cord from the thyroid cartilage. A recent case demonstrates this point well. This patient had received a series of six injections—including autogenous nasal cartilage ground with gelatin and Teflon without any improvement in her voice. A cartilage implant, as outlined in the article corrected this promptly, and her voice returned almost to normal.
I have no objection in trying to create mediofixation of the scarred abducted cord with injections of Teflon-glycerine. However, this has been unsuccessful in my hands in the traumatically abducted cord. This has rarely worked and has not been able to build up
