Abstract
Vocal fold paralysis is one of the diseases that particularly affect quality of life. While unilateral paralysis leads to glottis closure insufficiency and hoarseness, bilateral paralysis compromises respiration and limits the exercise tolerance. Bioimplants have been used to treat persistent paralysis for over 100 years. The spectrum ranges from autologous tissue transfer and resorbable or permanent injection materials to composite thyroplasty implants and active electrical implants for neurostimulation of the larynx. If bioimplants are used in accordance with the recommendations, the quality of life of affected patients can be significantly improved today.

Abstract
Objectives The purpose of this study was to explore the effects of injection laryngoplasty (IL) with hyaluronic acid in patients with vocal fold paralysis (VFP). Methods A total of 50 patients with VFP participated in this study. Pre- and post-IL assessments were performed, which included analyzing the sustained vowel /a/ phonation, and the patient reading 1 Korean sentence from the "Walk" passage that comprised 25 syllables in 10 words. To investigate the effect of IL on vocal fold function, acoustic analysis (acoustic voice quality index, cepstral peak prominence, maximum phonation time, speaking fundamental frequency) was conducted and auditory-perceptual (grade and overall severity), visual judgment (gap), and self-questionnaire (voice handicap index-10) assessments were performed. Results The patients with VFP showed statistically significant differences between pre-and post-IL assessments for acoustic and auditory-perception, visual judgment, and self-questionnaire assessments. Conclusion The patients with VFP showed positive change in vocal fold function between pre- and post-IL measurements. The findings showed that IL with hyaluronic acid is an effective method to improve vocal fold function in patients with VFP.

Abstract
OBJECTIVES To assess the integration of an autologous composite fascia and fat graft implanted into the lamina propria of a porcine vocal fold using two different approaches. STUDY DESIGN An experimental prospective study on the porcine larynx was conducted at a tertiary research institution. METHODS An external cervical approach was used to expose the thyroid cartilage of 24 healthy minipigs under general anesthesia. The composite fascia/fat graft was implanted through two distinct approaches, transmuscular and submuscular. Animals were sacrificed at 7, 30, 90, and 180 days for macroscopic and histological study of the larynx. Graft integration and local inflammatory response were studied. RESULTS The survival rate of the experimental model was 100% and all animals had local inflammatory response to the surgical procedure. Only 41.7% of the grafts placed inside the thyroarytenoid (TA) muscle fibers were identified postmortem, whereas 83.3% of the submuscular grafts remained intact. CONCLUSIONS Graft incorporation was better and there was less inflammation when the architecture of the TA muscle fibers was preserved. Graft extrusion was observed in the most of the cases where it was placed inside the muscle.

Abstract
OBJECTIVES Since 1997, we have performed the autologous transplantation of fascia into the vocal fold (ATFV) procedure on cases of sulcus vocalis. In what follows, we report the long-term results of our new surgical approach and discuss the role of these transplantations. We also review and report some complications that can be caused by ATFV. Finally, we discuss the ATFV technique as a contribution to the phonosurgery of the future. STUDY DESIGN Prospective study. METHODS We were able to obtain long-term results from 10 volunteer cases (2 female and 8 male, age: 15-71, mean 46.5 years old) who could be followed up for at least 3 years after transplantation. All were cases of pathologic sulcus vocalis.We measured maximum phonation time (MPT) and carried out pre- and postsurgical clinical observation and laryngeal stroboscopy in all cases. These measurements and observations were made before the ATFV and at 6 months, 1 year, 2 years, and 3 years after surgery. RESULTS In stroboscopic observation 1 year after the ATFV, satisfactory glottal closure and excellent mucosal wave were observed for all cases, and there was no case with hyperadduction of the false vocal folds. MPT measures remained at an improved level 2 years and 3 years after the transplantations. Paired-sample t tests showed that the improvement relative to preATFV levels was significant for all postsurgical measurements up to 3 years. CONCLUSIONS We conclude that ATFV is a successful surgical procedure for sulcus vocalis and scarred vocal folds. Other phonosurgical clinical applications may also be envisioned.

Abstract
OBJETIVO: analisar os parâmetros vocais acústicos e perceptivo-auditivos que se alteram com a cirurgia de implante de pré-fáscia do músculo temporal para sulco vocal estria maior. MÉTODOS: registraram-se as emissões vocais de 9 pacientes, 6 do sexo feminino e 3 do masculino, nas condições pré e pós-tratamento cirúrgico. As amostras vocais foram submetidas à avaliação perceptivo-auditiva por três fonoaudiólogas com experiência na área de voz, por meio de consenso utilizando a escala GRBAS e a análise acústica espectrográfica foi realizada por meio de consenso entre três estudantes do curso de Fonoaudiologia após treinamento visual com a duração de três horas, utilizando o programa GRAM 5.1. RESULTADOS: houve tendência de a freqüência fundamental apresentar-se mais grave e o tempo máximo de fonação aumentou. Por meio da análise estatística observou-se que somente o parâmetro B apresentou melhora estatisticamente significante (t>1,734), os outros parâmetros G, R e S não mostraram melhora estatisticamente significante. Na análise espectrográfica observou-se que a forma e a continuidade do traçado permaneceram estáveis, a presença de ruído diminuiu e número de harmônicos aumentou. CONCLUSÃO: os pacientes submetidos à cirurgia de implante de Pré-Fáscia do Músculo Temporal apresentaram melhora no aspecto perceptivo-auditivo de soprosidade (B), na freqüência fundamental, tempo máximo de fonação e nos aspectos espectrográficos de presença de ruído e aumento do número de harmônicos, houve também tendência da freqüência fundamental apresentar-se mais grave após a cirurgia.

Abstract
Uma das alterações mais complexas que acometem as pregas vocais é a incompetência ou insuficiência glótica. Pode ser causada por alterações de mobilidade, fibroses, atrofias ou arqueamento das pregas vocais, e pode levar, entre outras situações como aspiração e tosse pouco efetiva, a graus variados de disfonia. A partir do início do século 20, surgiram vários procedimentos cirúrgicos para a reabilitação da competência aerodinâmica e valvular da glote, por meio da injeção de substâncias heterólogas no espaço paraglótico. Os enxertos autólogos, como a gordura e a fáscia muscular, inseridos ou injetados nas pregas vocais inicialmente mostraram resultados promissores além de segurança e riscos mínimos de reações indesejadas. Neste artigo de revisão, os autores discutem o uso da gordura e da fáscia muscular na incompetência glótica, abordando aspectos históricos, o processo inflamatório gerado após a enxertia, as técnicas cirúrgicas mais utilizadas e o rendimento dos enxertos.

Abstract
The main symptom of unilateral vocal fold palsy is hoarseness, which can cause considerable disturbance to the patient depending on its extent and the patient's individual situation. Therapy aims at the restitution of a tuneful and resilient voice, which can be achieved by surgical or conservative means, improving the glottal closure and synchronizing the vocal fold vibrations during phonation. Vocal therapy is a common conservative method that may be supported by psychotherapeutic or physical procedures. In surgical therapy, there is a distinction between techniques of endoscopic augmentation by injecting different materials into the vocal folds and transcutaneous laryngeal framework surgery, i.e., transferring the paralyzed vocal fold to the glottal midline. Particularly apt for injection are biocompatible materials amount and position whose can easily be controlled. However, the inevitable resorption of many materials causes deterioration in voice quality. Furthermore, the change of vocal fold morphology obstructs regular phonatory vibration. On the other hand, medialization thyroplasty leads to permanent voice amelioration without a substantial complication rate when performed by experienced surgeons.

Abstract
Several materials have been injected or introduced in the vocal folds in attempt of solving the glottic insufficiency. However, few studies have evaluated the cicatricial process due to the implantation of these materials. Aim The objective of this research was to evaluate the concentration of collagen after microsurgery graft of muscular fascia and fat in the vocal folds of rabbit. Study design experimental. Material and Method Nineteen rabbits were submitted to the graft insert in the right vocal fold, being nine of fascia and ten of fat. The left vocal fold was submitted to the same process, except for the insertion of fat or fascial graft. The rabbits were sacrificed after 90 and 180 days. The collagen was analyzed through the method of the Picrosirius-polarization using the Image Pro Plus software. Results There was prevalence of the collagen in all grafted groups when compared with the group control. The concentration of the collagen found in the rabbits submitted to fat graft was significantly larger when compared to the concentration of the rabbits submitted to graft of muscular fascia, either with 90 as with 180 days. Conclusion The fat and muscular fascia implantation in the vocal folds of rabbit promoted production of collagen, being more intense with fat.

Abstract
Values for acoustic voice measurements were obtained from 88 normal individuals and 98 pathological cases of mass lesions of vocal fold and 50 cases of unilateral vocal fold paralysis. Overall, all items reflecting perturbations of pitch and amplitude as well as glottal noise were significantly higher in the groups of patients compared with the normal group. The measurement of normalized noise energy (NNE) was found to be an optimum parameter for discrimination of normal/abnormal voices. The voices of patients with vocal fold nodules and vocal fold polyps were analyzed before endolaryngeal phonomicrosurgery (EPM) and 2 weeks after. Statistically significant (p < 0.01) improvement was achieved both in perceptual and acoustic analysis. EPM resulted in a significant decrease of mean jitter, shimmer, and NNE. Clinically, these measures provided documentable and measurable evidence of vocal function and were helpful for comparing patients with normal speakers. They also were useful for a thorough documentation of patient's voice pathology and for evaluation of the presurgical and postsurgical voice status.

Abstract
Vocal fold augmentation by injection laryngoplasty is a simple and fast procedure. The aim of this prospective study was to assess the glottal closure and the travelling mucosal wave by videostroboscopic images after autologous fascia augmentation in unilateral vocal fold paralysis (UVFP) with a special reference to objective analysis of voice. A total of 14 UVFP patients with poor voice and open glottal gap were assessed by videostroboscopy, blinded perceptual evaluation of running speech and acoustical analysis of sustained vowel. Data were collected before the procedure and at a supplementary evaluation 5-32 months (mean: 13 months) after injection of autologous fascia deep into the paralysed vocal fold. Mean age was 59 years; there were eight women and six men. Frame-by-frame video analysis revealed that before the operation 10 out of 12 had large glottal gaps without any contact between vocal folds on phonation. After the procedure seven gaps were completely closed, four partly, and two had no mucosal contact in stroboscopic examination. Maximum gap between vocal folds decreased from 7.21 units to 1.65 units (paired t-test P<0.001). Mucosal wave amplitude symmetry and phase synchrony were present in most subjects with partial closure and phase synchrony in every patient with a proper glottic closure. A panel of listeners rated voice to be significantly better ( P<0.01) ) after the procedure, and the improvement in acoustical parameters was also statistically significant ( P<0.01). There was a good correlation between objective voice analysis and videostroboscopy. Residual glottal gap was the major reason for less than optimal postoperative voice. No signs of hampered mucosal wave were noticed. Videostroboscopy and objective voice analysis suggest that augmentation by autologous fascia does not induce scar or fibrous tissue in the subepithelial space. Slight over-correction should be attempted initially in order to accomplish sufficient augmentation. This might enhance complete glottic closure and improve the outcome.

Abstract
There are three surgical methods utilized in treating glottic insufficiency: laryngeal framework surgery, reinnervation procedures and injection medialization. The trend towards the use of less invasive procedures led us to focus on injection medialization in this study. The advantages of vocal fold injection are that the procedure requires no external incisions, is easily applicable and can be applied in an office setting. Furthermore, injection medialization is applicable in cases of atrophic vocal fold and vocal fold scarring. In developing injection medialization, laryngologists are in search of an "ideal material" that should be biocompatible and resistant to resorption. In the initial applications of this method, synthetic materials were used. In the past 2 decades, however, researchers have become more and more interested in the advantages of biological materials. In our animal study, we investigated the behavior of AlloDerm and autologous skin injected in the quadriceps muscles of rats. The materials were easily injected. Histopathological and volumetric analyses were done; the rats were sacrificed the 1st day post-injection and subsequently in the 1st, 3rd and 6th months. AlloDerm's absorption levels were generally high, and its inflammation and fibrosis levels were low and medium. In the 6th month, histiocytic foreign body reaction was observed. The mean graft yield was 4.5%. Autologous skin results for inflammation and fibrosis levels were similar to those of AlloDerm. However, no foreign body reaction was observed in AS injected muscle. The graft yield was 74.6%. The growth of keratin cysts had an effect on the results of the graft yield.

Abstract
After a nearly a century of development, augmentation of laryngeal tissue through injection remains as complex a procedure as it was in the earlier part of the century. Initially, the number of surgeons performing injection laryngoplasty was limited since the technique of injection was thought to be difficult and the selection of cases was thought to require the judgment of an accomplished laryngologist. Performing successful injection laryngoplasty does in fact require an understanding of laryngeal anatomy and physiology, and the physical characteristics of the substance to be injected. In addition, the surgeon must be aware of potential host reactions to the injected material. Finally, the surgeon must have an understanding of the etiology and configuration of the glottic insufficiency, and keep in mind the goals of the procedure.

Abstract
The criteria used to determine the success or failure of a given treatment for vocal fold paralysis are fundamental components of routine clinical practice and treatment outcomes research for the surgeon and voice therapist. The purpose of this article is to offer a guide to the critical interpretation of available measures of out-come and efficacy for this patient population. Such data form the basis for the practice of evidence-based medicine and voice therapy,essential if the standard of care is to evolve to the benefit of the patient. A better understanding of the potentials and limitations of each measure is important for treatment planning and patient counseling and, ultimately, for the conception of future well-designed clinical research. The complex issues regarding outcomes measurement are addressed here within the context of current treatment literature on vocal fold paralysis. Particular emphasis is placed on realistic data gathering within clinical practice.

Abstract
PURPOSE OF REVIEW Glottic insufficiency secondary to vocal fold scarring, atrophy, or paresis remains a clinically challenging problem for the laryngologist. Numerous methods have been described in the treatment of glottic insufficiency, belying the complexity of the problem. Type I thyroplasty and injection of fat, fascia, and gelatin powder have been the mainstay of treatment to date, but the ability to restore a normal mucosal waveform to a damaged vocal fold remains an elusive goal. RECENT FINDINGS Advances in the material and biomedical sciences have allowed the introduction of newer substances and techniques not only to medialize the vocal fold but also to help restore its viscoelastic properties as well. These substances include expanded polytetrafluoroethylene (ePTFE), collagen, cross-linked hyaluronic acid, micronized acellular human dermis calcium hydroxyapatite, and polydimethylsiloxane. ePTFE can be introduced through a window in the thyroid ala or placed intracordally, and the others can be injected either transorally or transcutaneously, allowing in-office placement under simple topical anesthesia. SUMMARY Although the ideal augmentation material and technique have yet to be devised, the laryngologist now has several options with which to address the problem of glottic insuffiency. Since the problem is complex and since it is possible that a customized solution may need to be devised on an individual basis, future laryngologists will need to be comfortable with the indications and applications that each material and technique will afford.

Abstract
OBJECTIVES To apply the technique of autologous transplantation of fascia graft into the vocal fold for glottal insufficiency due to recurrent nerve paralysis and to evaluate the results in eight patients who underwent the procedure. STUDY DESIGN Technical modifications were made in transplantation of the temporal fascia into the paralyzed vocal fold. Eight patients underwent the surgery, and their phonatory function was examined preoperatively and postoperatively. METHODS The following surgical techniques were applied to prevent the falling-off of the graft: 1) a roll-shaped fascia graft was prepared before the transplantation and 2) a pocket was made within the lamina propria mucosa using a newly devised special elevator. The maximum phonation time and airflow rate during sustained phonation (in four cases) were measured, and perceptual evaluation of voice quality was made using the GRBAS scale by speech pathologists before and after the surgery. RESULTS All the cases showed no evidence of falling-off of the graft. Elongation of the maximum phonation time and improvement in voice quality were obtained in all cases postoperatively. CONCLUSION The method proved to be useful for the treatment of glottal insufficiency due to recurrent nerve paralysis.

Abstract
OBJECTIVE This report provides the reader with a state-of-the-art update on a number of common voice problems that require phonosurgical intervention. STUDY DESIGN AND SETTING This multiauthor review is not a position statement of the American Academy of Otolaryngology-Head and Neck Surgery (AAOHNS) and may reflect institutional preference and/or bias. It arose from a panel discussion at the AAOHNS meeting in 2000. RESULTS We provide a review of the genesis and management of papillomatosis, dysplastic glottal epithelium, arytenoid granulomas, Reinke's edema, and vocal-fold paralysis. CONCLUSIONS AND SIGNIFICANCE In the past decade, there has been a dramatic expansion of knowledge regarding a variety of voice disorders and associated treatment. There has been a convergence of basic science investigations in anatomy, physiology, and pathology with clinical trials of treatment, both surgical and nonsurgical. This information should provide the reader with current insight into critical management issues of the aforementioned disorders.

Abstract
OBJECTIVE To evaluate the histology of minced and injected autologous fascia graft in the augmentation of unilateral vocal fold paralysis. STUDY DESIGN Prospective study using a canine model. METHODS Nine dogs were operated. At first, a piece of fascia was harvested from fascia lata and minced into tiny chips with a scalpel. Cutting off a section of the recurrent nerve paralyzed the right vocal fold. The minced fascia-paste (0.1 mL) was injected using a pressure syringe into the paralyzed thyroarytenoid muscle under direct laryngoscopy. Two animals were killed at 3 days, one at 10 days, three at 6 months, and three at 12 months postinjection. Each dog underwent laryngectomy and serial coronal sections of paraffin blocks from the posterior part of the vocal folds were made. RESULTS The dogs experienced no complications perioperatively or during follow-up. Under microscopy, muscle of the paralyzed vocal fold was atrophied in comparison to the contralateral control. There was an acute inflammatory reaction induced by the graft. This did not exist in the specimens taken at 6 and 12 months. No extensive edema, areas of necrosis, or formation of granulomas was seen at any time. Maturation of the graft was characterized by active collagen remodeling up to 12 months. At that time the graft consisted of firm, condensed fibrous tissue. Scar formation around the graft was moderate, and the subepithelial layer of the vocal fold remained undisturbed. Each graft consisted of singular foreign bodies from the polyamide mincing plate. We cannot exclude that their presence would have had an impact on the final architecture of the graft. CONCLUSION In a canine vocal fold, the free fascia graft is well tolerated and after 12 months a well-organized, collagen rich tissue is seen on histological sections. The findings are in accordance with clinical studies applying free fascia grafts.

Abstract
OBJECTIVES To study the long-term results of autologous transplantation of fascia into the vocal fold, and to evaluate our use of autologous transplantation instead of bovine collagen injection in cases of glottal incompetence. STUDY DESIGN Retrospective study of the patients who have undergone autologous fascia transplantation using our new technique. METHODS Follow-up studies were performed for at least 1 year (up to 3 y) on 9 autologous fascia transplant patients (6 cases with type 1 procedures and 3 cases with type 2 procedures). Clinical observations, including laryngeal stroboscopy, and measurement of maximum phonation time (MPT) were carried out. RESULTS During 3 months after autologous fascia transplantation, MPT gradually increased and stroboscopy showed improved glottal closure. These improvements continued beyond 1 year in all cases of type 1 surgery and 2 of 3 cases of type 2 surgery. CONCLUSIONS Autologous transplantation of fascia into the vocal folds as a phonosurgical treatment for glottal incompetence yields excellent long-term results. Temporal fascia appears to be a highly suitable tissue for transplantation in Reinke's space. However, the fascia is less suitable for transplantation in the muscle. We speculate that transplantation of temporal fascia leads to regeneration of vocal fold tissue, perhaps using a mechanism similar to stem cell transplantation in other organs.
