This well-illustrated book provides step-by-step guidance on the various techniques – microlaryngoscopic, fiberoptic endoscopic and transcutaneous – that can be employed for the purpose of injection laryngoplasty, a surgical procedure in which a foreign material is injected into the vocal fold. The anatomy and function of the region are first explained, with identification of the causes and means of evaluation of glottic and neoglottic insufficiency. Advice is then provided on the choice of material for injection laryngoplasty, including absorbable and long-lasting options, on the basis of careful analysis that takes into account both the recent literature and the authors’ own experiences. Detailed descriptions of the surgical indications and different procedures follow and for ease of reference, clear flow charts on diagnosis and indications are also included. The book concludes with chapters on the use of injection laryngoplasty specifically in the pediatric population and on postoperative care and speech therapy following the procedure. Injection Laryngoplasty will provide valuable assistance to all surgeons wishing to perform this kind of surgery.

This book provides step-by-step illustrated descriptions of diverse vocal fold injection techniques, including some not previously described. The aim is to provide laryngologists in general, and especially those who are less experienced, with the detailed understanding and guidance needed in order to achieve optimal outcomes. Highly experienced experts describe approaches via the transoral, transnasal, and transcutaneous routes and offer guidance on indications, injection materials, pre- and postoperative care, and the management of complications. Special considerations that must be borne in mind when employing different vocal fold injection techniques, in different settings, are also carefully explained. In offering comprehensive, up-to-date information on this minimally invasive and cost-effective procedure, Vocal Fold Injection will be an essential aid for practitioners.

"Objectives: The objective of this study was to evaluate the phonatory function of rabbit larynges 42 days after surgical injury of the vocal folds and immediate injection treatment of dexamethasone, hyaluronic acid/gelatin hydrogel, glycol-chitosan solution or saline as a control. Methods: A modified microflap procedure was performed on the left vocal fold of 12 rabbits to induce an acute injury. Animals were randomized into one of four treatment groups with 0.1 mL injections of dexamethasone, hyaluronic acid/gelatin hydrogel, glycol-chitosan or saline as control. The injection was performed at the level of the lamina propria of the left mid vocal folds, immediately following the injury. Right vocal folds served as uninjured controls. Larynges were harvested at Day 42 after injection, and were subjected to airflow-bench evaluation. Acoustic, aerodynamic and laryngeal high-speed videoendoscopy (HSV) analyses were performed. In addition, HSV segments of the vibrating vocal folds were rated by three expert laryngologists on six parameters related to vocal fold vibratory characteristics on a Likert scale.Results: The fundamental frequency, one possible surrogate of vocal fold stiffness and scarring, appeared to be lower in all treatment groups compared to that of the saline control (411.52 11.63 Hz). The lowest fundamental frequency value was observed in the dexamethasone group (348.79 14.99 Hz). Expert visual ratings of the HSV segments indicated an overall positive outcome in the Dexamethasone treatment group. Conclusion: Dexamethasone injections might be a useful intraoperative adjunct to guide the vocal fold healing process after surgical injury. An increased sample size and a histological correlate would be helpful to confirm this finding. " --

"AbstractObjectives/Hypothesis: The primary objective of this study was to investigate the healing potential of a novel hierarchically micro-structured Hyaluronic Acid (HA)-gelatin (Ge) hydrogel in the treatment of acute vocal fold injury using a rat model. A secondary objective was to evaluate the feasibility of the rat vocal fold for scar and injection studies.Study Design: Experimental Randomized Prospective StudyMethods: Vocal fold injury was performed unilaterally in 36 rats. The animals were stratified into three groups. Each group had 25 μl of either saline, HA bulk or HA-gelatin hydrogel injected into the lamina propria five days after injury. Vocal folds were then harvested at 56 days after injection and were analyzed using immunohistochemistry. Immunofluoresence staining was performed on collagen type I, collagen type III and elastinResults: No major reaction to the injectable material was observed. When comparing protein densities between the right injured and left uninjured vocal fold; Type I collagen densities was higher in the saline and HA-Ge groups relative to the uninjured samples (p=0.31 and 0.917 respectively). Collagen type III densities, on the other hand, were greater than in the uninjured controls in both HA-bulk and HA-GE groups (p=0.012 and 0.028 respectively). The density of elastin was higher in the HA-bulk and HA-GE groups when compared to the uninjured vocal folds but statistically significant in only the HA-GE group (P=0.128 and 0.036 respectively).On the other hand, when comparing protein densities on the right vocal fold between the treatment groups; we found The relative densities of elastin and collagen III were greater in the HA-bulk group than in the saline group (p = 0.032 and 0.07, respectively). Likewise, elastin and collagen type III were of greater densities in the HA-GE group than in the saline group (p =0.014 and 0.004, respectively).Conclusions: Local HA-gelatin injection shows some potential tissue remodeling and did not cause any inflammatory response during the course of this study. The rat vocal fold is an excellent model for laryngeal studies." --

This guide brings thought leaders and master clinicians together to share their wisdom and expertise regarding clinical decisions surrounding unilateral and bilateral vocal fold paralysis. Designed as a what- to-do and why as opposed to a how-to guide, the authors detail the reasoning process from work up, through intervention, to post-treatment decision making. The text is organized around decision points in the management of vocal fold paralysis such as decisions in regard to timing, intervention, implants, reinnervation, drugs, voice therapy, and post-operative care. Individual chapters focus on specific steps in the process of evaluation and treatment, explore the decisions that can and should be made, and provide answers and direction for the reader. Authors explain the issues around the decision point and use their considerable experience to offer their opinion and as well as the thought process behind it. Decision Making in Vocal Fold Paralysis will be a useful guide for practitioners that deal with vocal fold paralysis, including otolaryngologists, general surgeons, neurologists, speech language pathologists, primary care physicians, and oncologists.
