Vocal Rehabilitation of Paralytic Dysphonia: VIII. Phoniatric Methods of Vocal Compensation

Vocal Rehabilitation of Paralytic Dysphonia: IX. Technique of Intracordal Injection

“…[4][5][6][7][8][9][10][11] In the meantime, other authors have confirmed our experiences and suggested that further studies should be undertaken.14- 16,18 The principle of restoring the voice through narrowing a deficient glottis has been corroborated also by J. G. Waltner,20 who implanted a cartilaginous graft lateral to the cicatricial cord with good functional results. It seems to be the consensus of these opinions that intracordal injection is a suitable method for vocal rehabilitation in various conditions when the vocal disability is due to insufficient closure of the vocal cords during phonation.…”

“…These matters have been recent¬ ly discussed. 11 2. For the same reason, injection should not be considered before 6 months have elapsed since the onset of laryngeal paralysis.…”

Ansa Cervicalis Nerve: Review of the Topographic Anatomy and Morphology

“…In the past few decades, laryngology has witnessed a dramatic proliferation of surgical procedures designed for the treatment of dysphonia secondary to unilateral paralysis of the vocal cord. They include medialization procedures such as Teflon (DuPont, Wilmington, DE) injection, 1 thyroplasty, 2 and arytenoid adduction, 3 and reinnervation procedures such as nerve‐muscle pedicle implantation 4 and nerve‐nerve anastomosis using ansa cervicalis nerve transfer to the recurrent laryngeal nerve 5 . Reinnervation procedures are purported to work by preventing vocal cord atrophy and maintaining symmetric vocal cord mass and tension 5 …”

How I Do It: Miniplate Reconstruction of the Lateral Thyroid Lamina: One-Stage Restoration of Voice After Teflon Granuloma Resection

“…1 It is injected lateral to the thyroarytenoid muscle of the involved vocal fold to improve glottic closure. Because of its ease of use, Teflon quickly became a popular method for vocal fold medialization for a number of years.…”
