Abstract
Objectives: Laryngeal keel insertion, mucosal suture, application of mitomycin-C (MMC), and staged operations are approaches to prevent the anterior glottic web, but there are limitations. Our study suggests a modified approach to prevent the formation of an anterior glottic web. Methods: This retrospective single-institution tertiary center study (N = 23) involved the simultaneous removal of bilateral vocal fold lesions with topical MMC application. If exudate was identified after 4 to 6 weeks, second laryngomicroscopic surgery (LMS) was performed to remove it with topical MMC application. Extent of anterior glottic web was measured as a percentage of the total length of the membranous vocal fold. Results: After the initial surgery, 18 patients recovered without anterior web or fibrin exudate. Thick exudate was observed in 5 patients. After the second LMS, all patients showed improvement and did not develop anterior web. Conclusion: This modified method has been developed to prevent the anterior glottic web without complications.

[PMID: 34353684 PMCID: PMC8807745 DOI: 10.1016/j.jvoice.2021.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 05/28/2021] [Accepted: 06/02/2021] [Indexed: 02/04/2023]
Abstract
OBJECTIVES The objective of this study was to evaluate the efficacy of immediate injection treatments of dexamethasone, hyaluronic acid (HA)/gelatin (Ge) hydrogel and glycol-chitosan solution on the phonatory function of rabbit larynges at 42 days after surgical injury of the vocal folds, piloting a novel ex vivo phonatory functional analysis protocol. 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, HA/Ge hydrogel, glycol-chitosan or saline as control. The left mid vocal fold lamina propria was injected immediately following injury. The right vocal fold served as an uninjured control. Larynges were harvested at Day 42 after injection, then were subjected to airflow-bench evaluation. Acoustic, aerodynamic and laryngeal high-speed videoendoscopy (HSV) analyses were performed. HSV segments of the vibrating vocal folds were rated by three expert laryngologists. Six parameters related to vocal fold vibratory characteristics were evaluated on a Likert scale. RESULTS The fundamental frequency, one possible surrogate of vocal fold stiffness and scarring, was lower in the dexamethasone and HA/Ge hydrogel 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, though the impacts were below statistical significance. CONCLUSION Dexamethasone injections might be used as an adjunctive option for iatrogenic vocal fold scarring. An increased sample size, histological correlate, and experimental method improvements will be needed to confirm this finding. Results suggested a promising use of HSV and acoustic analysis techniques to identify and monitor post-surgical vocal fold repair and scarring, providing a useful tool for future studies of vocal fold scar treatments.

Abstract
Benign vocal fold lesions cause dysphonia by preventing vocal fold closure, causing irregular vibration and increasing compensatory muscle tension. Voice therapy delivered in addition to phonosurgery may improve voice and quality of life outcomes but the evidence base is lacking and what constitutes voice therapy for this population is not defined. The purpose of this systematic review is to critically evaluate the evidence for pre and post-operative voice therapy to inform the development of an evidence based intervention. STUDY DESIGN Systematic Review. METHODS Electronic databases were searched using key terms including dysphonia, phonosurgery, voice therapy and outcomes. Eligible articles were extracted and reviewed by the authors for risk of bias and for information regarding the content, timing and intensity of any pre and post-operative voice therapy intervention. RESULTS Of the 432 articles identified, 35 met the inclusion criteria and were included in the review. 5 were RCTs, 2 were individual cohort studies, 1 was a case control study and 26 were case series. There was considerable heterogeneity in participant characteristics. Information was frequently lacking regarding the content timing and intensity of the reported voice therapy intervention, and where present, interventions were highly variable. CONCLUSION Reporting in relevant literature is limited in all aspects of content, timing and intensity of intervention. Further intervention development work is required to develop a robust voice therapy treatment intervention for this population, before effectiveness work can commence.

Abstract
OBJECTIVE To offer pragmatic, evidence-informed guidance on the use of systemic corticosteroids (SCS) for common otolaryngologic disorders. DATA SOURCES PubMed, Cochrane Library, and American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guidelines. REVIEW METHODS A comprehensive search of published literature through November 2021 was conducted on the efficacy of SCS, alone or in combination with other treatments, for managing disorders in otolaryngology and the subdisciplines. Clinical practice guidelines, systematic reviews, and randomized controlled trials, when available, were preferentially retrieved. Interventions and outcomes of SCS use were compiled to generate summary tables and narrative synthesis of findings. CONCLUSIONS Evidence on the effectiveness of SCS varies widely across otolaryngology disorders. High-level evidence supports SCS use for Bell's palsy, sinonasal polyposis, and lower airway disease. Conversely, evidence is weak or absent for upper respiratory tract infection, eustachian tube dysfunction, benign paroxysmal positional vertigo, adenotonsillar hypertrophy, or nonallergic rhinitis. Evidence is indeterminate for acute laryngitis, acute pharyngitis, acute sinusitis, angioedema, chronic rhinosinusitis without polyps, Ménière's disease, postviral olfactory loss, postoperative nerve paresis/paralysis, facial pain, and sudden sensorineural hearing loss. IMPLICATIONS FOR PRACTICE Clinicians should bring an evidence-informed lens to SCS prescribing to best counsel patients regarding the risks, anticipated benefits, and limited data on long-term effects. Alternate routes of corticosteroid administration-such as sprays, drops, inhalers, and intralesional injections-may be preferable for many disorders, particularly those that are self-limited or require a prolonged duration of therapy. Prudent use of SCS reduces the risk of medication-related adverse effects. Clinicians who are conversant with high-level evidence can achieve optimal outcomes and stewardship when prescribing SCS.

Abstract
OBJECTIVES To investigate the added value of steroid injection following office-based blue laser therapy of benign lesions of the vocal folds. STUDY DESIGN Retrospective cohort analysis. METHODS The medical records and video-recordings of patients with benign lesions of the vocal folds who underwent office-based blue laser therapy in a tertiary referral center between February 2020 and October 2022 were reviewed. Patients were divided into two subgroups, those who underwent office-based blue laser therapy alone (n = 23) and those who underwent office-based blue laser therapy with steroid injection (n = 19). Disease regression and voice outcome measures included Voice Handicap Index-10 score, perceptual voice evaluation using the GRB grading, jitter, shimmer, noise to harmonic ratio, voice turbulence index, and maximum phonation time were reviewed. RESULTS A total of 42 patients were included. The mean age was 54.7 ± 10.1 years. Lesions included polyps (n = 21), Reinke's edema (n = 19), and cysts (n = 2). There was partial or complete disease regression in all patients who presented for follow-up (n = 37). In patients who underwent blue laser therapy alone (n = 19), 42.1% had complete regression and 57.9% had partial regression. In those who underwent blue laser therapy followed by steroid injection (n = 18), 77.7% had complete disease regression and 22.3% had partial regression. The difference in disease regression between the two subgroups was statistically significant (P = 0.027). The decrease in the mean Voice Handicap Index-10 score was also statistically significant with a higher mean being noted in the subgroup who underwent blue laser therapy followed by steroid injection (-10.5 ± 6.9 vs. -17.3 ± 11.8, P = 0.031). There was no significant difference in the decrease in the perceptual evaluation scores nor in the decrease in jitter, shimmer, noise to harmonic ratio, and voice turbulence index between the two subgroups. There was also no significant increase in the maximum phonation time. CONCLUSION Steroid injection after blue laser therapy improves disease regression and voice outcome of laser therapy.

Abstract
Objective Benign vocal fold lesions (BVFLs) cause voice disorders and impair social life. Recently, office-based vocal fold steroid injection (VFSI) has gained attention as a minimally invasive treatment for BVFLs. This study aimed to analyze the age-dependent treatment effect of VFSI and to clarify the indications for treatment. Methods In this retrospective cohort study, a total of 83 patients with BVFLs were treated with a similar regimen of VFSI. Three or four months after the injection, age-dependent phonological functions were evaluated. The differences between pre- and post-treatment findings were analyzed using the Wilcoxon matched-pair signed-rank test, and the correlation between patient age and improvement rates were determined by Pearson's correlation coefficient. Results Improvement in voice handicap index (VHI), which was the primary endpoint, was observed. Subjective and objective voice quality measurements also showed significant improvements. Subgroup analyses revealed that there was no age-related difference in the improvement of voice quality and that there was no improvement in aerodynamic effect in patients over 45 years of age. Conclusion This study clarified the age-dependent treatment effect of VFSI and provided the important suggestion of establishing indication criteria for BVFLs. The study results provided clarity on the indication criteria of VFSI and served as an important indicator for tailoring treatment to patients' needs. Level of Evidence 4.

Abstract
OBJECTIVES Benign vocal fold lesions which include vocal fold nodules, polyps, cysts and other lesions often recur after surgery and require additional treatments. This systematic review of the current literature evaluated the effects of adjunctive therapies in addition to surgical resection on the recurrence rates of benign vocal fold lesions in adults. STUDY DESIGN Systematic review. METHODS A search using relevant keywords in electronic databases was conducted. Extracted data include author, year of publication, patient demographics, diagnostic approach, lesion type, surgical procedure, type of adjunctive therapy and the rates of recurrence. Descriptive statistics were performed on the collected data when appropriate. RESULTS Eleven articles were identified with a total of 1085 patients. The total 1101 lesions studied included 591 (53.7%) polyps, 125 (11.4%) nodules, 146 (13.3%) cysts, 184 (16.7%) pseudocysts, 19 (1.7%) midfold masses, 18 (1.6%) sulcus vocalis and 18 (1.6%) varices. Besides surgery, adjunctive therapies included voice therapy, steroid injection and reflux medication. There were 141 reported lesion recurrences, with an average recurrence rate of 13.0%. The recurrence rate in studies with adjunctive therapies was 7.14%, and in studies with no adjunctive therapies it was 24.44%. CONCLUSIONS Available evidence suggests that adjunctive therapies following surgery are associated with decreased lesion recurrence rates. However, due to differences in sample size, inconsistent reporting of lesion characteristics, heterogeneity of adjunctive therapies, variability in follow-up time across studies, and other factors, it is not possible to determine exactly which adjunctive therapies are of significant benefit and which lesion types may benefit the most.

Abstract
PURPOSE OF REVIEW Vocal fold (VF) fibrosis remains an insoluble problem in most cases, with a severe impact on vocal quality and effort. This review examines current investigations and research strands that explore the understanding of VF wound healing and applied treatments for the management of VF scar. RECENT FINDINGS Recent work focused on VF fibrosis has examined wound healing in the glottis, fibrosis-modifying medication, and tissue engineering approaches that span cytokine and growth factor therapy, scaffold and cell delivery platforms, seeded scaffolds, conditioned media and stem cell therapy. Many show promise and may deliver improvements in the wound bed favouring less fibrogenic healing patterns, ultimately with the goal of preserving or restoring VF vibration. Further collaborative research is required that examines combined approaches, long term outcomes, better three-dimensional modelling of cell-cell interactions and delivery modalities for molecular therapies. SUMMARY VF fibrosis research continues to expand and explore a variety of mechanistic pathways in order to understand VF healing and identify novel and complementary targets for manipulation. Many different approaches show promise and may also offer synergistic benefits. Research continues to strive for healing that more closely resembles true VF architecture and function.

Abstract
BACKGROUND Benign vocal fold lesions (BVFLs) can cause voice changes, including reduced loudness and pitch range. In recent times, with progression in endoscopic technology, office-based vocal fold steroid injection (VFSI) has been used as an alternative therapy for BVFLs. AIMS/OBJECTIVES In this study, we analyzed the efficacy and safety of VFSI to investigate the mechanism underlying its therapeutic effects and determine the conditions in which VFSI will be most effective. MATERIALS AND METHODS In this retrospective cohort study, we included 40 condition-matched patients (8 patients per lesion) with chorditis, vocal nodules, vocal polyps, Reinke's edema (RE), or vocal scars who received similar regimens of steroid injection using a commercial preparation of triamcinolone acetonide. Their phonological outcomes were evaluated 2 or 3 months after the injection. RESULTS Significant improvements were observed in Voice Handicap Index scores, results of laboratory voice evaluation, and voice quality measured using the Grade, Roughness, Breathiness, Asthenia, Strain scale in all participants. In subgroup analysis, VFSI was highly effective against chorditis and vocal nodules, but less effective against RE and vocal scars. CONCLUSIONS Single-dose VFSI is valuable as an alternative to voice rehabilitation and laryngo-microsurgery, but higher concentrations or repeated injections are required for intractable lesions.

Abstract
OBJECTIVES To evaluate antifibrotic effects of corticosteroids and halofuginone, a small molecule inhibitor of Smad3, in an ovine model of vocal fold (VF) injury. METHODS Thirty sheep, using a paired study design, underwent controlled right VF injury by biopsy and then were treated with either no treatment, oral dexamethasone, intralesional triamcinolone, or oral halofuginone. Larynges were evaluated for histological evidence of fibrosis, immunohistochemical presence of Smad3, and vibratory parameters. Outcomes were compared across treatment groups. RESULTS Following injury, VF collagen density decreased in both halofuginone-treated and dexamethasone-treated sheep but not in triamcinolone treated sheep. A significant difference was noted between halofuginone and triamcinolone treated sheep (27.8% vs 37%, P = .017). Elastin was preserved postinjury by halofuginone treatment in contrast with all steroid treated animals where significant loss of elastin was noted (P <.05). Smad3 staining was up-regulated at all injury sites compared to normal left VFs however halofuginone and dexamethasone treatment reduced Smad3 activity significantly whereas triamcinolone treatment did not (P <.05). Ex-vivo stroboscopic evaluation demonstrated mucosal wave in all excised larynges with a normalized glottal gap less than 3, suggesting adequate glottal closure. CONCLUSIONS VF injury in an ovine model results in a wound response able to be modified by Smad3 inhibitor, halofuginone, with benefit to vibratory function. Halofuginone treated sheep demonstrated reduced collagenization of lamina propria with greater elastin density after injury, than sheep treated with either steroid medication. These data support this pathway as a suitable target for manipulation to prevent or reverse fibrosis in the glottis and restore voice quality.Level of Evidence: NA.

Abstract
OBJECTIVES There are emerging reports of the effectiveness of in-office awake vocal-fold corticosteroid injection in the treatment of exudative vocal-fold lesions. The aim of this study was to review this therapy and specify indications, practical modalities and outcomes. STUDY DESIGN Systematic review of the literature without meta-analysis. METHODS A systematic review by PubMed search for the period January 2000 to December 2018 was carried out. RESULTS Nine articles were included, for a total of 502 lesions: nodules (46.4%), polyps (31.7%), and Reinke's edema (21.9%). Submucosal injection of low-dose triamcinolone acetonide (0.1 to 0.3mL) was transoral, transcutaneous or transnasal via flexible endoscope with operating channel. Lesion volume was significantly reduced in more than 90% of cases, with significant vocal improvement in all studies. Relapse rates ranged between 4% and 31%, with time to relapse of 1 to 40 months. CONCLUSIONS First-line treatment of exudative glottic lesions by submucosal corticosteroid injection provides at least transient significant reduction in lesion volume and vocal improvement. It is consensually reserved to moderate-sized mainly exudative lesions without fibrosis. In-office injection provides an immediate therapeutic response in case of vocal impairment, enabling surgery under general anesthesia to be postponed.

Abstract
PURPOSE OF REVIEW Benign vocal fold lesions (BVFLs) cause dysphonia by preventing full vocal fold closure, interrupting vibratory characteristics and increasing compensatory muscle tension. Management includes phonosurgery, voice therapy, pharmacological treatment or more commonly a combination of these interventions. This review aims to present current perspectives on the management of BVFLs, particularly exploring the role of voice therapy. RECENT FINDINGS The review highlights variation in the management of BVFLs. There is evidence that phonosurgery is a well tolerated and effective intervention for BVFLs. Primary voice therapy can frequently prevent surgery in vocal fold nodules and some types of polyps. Used as an adjunct to phonosurgery, preoperative and postoperative voice therapy can improve patient-reported outcomes and acoustic parameters of the voice. However, heterogeneity of studies and poor descriptions of intervention components prevent a robust analysis of the impact of voice therapy. SUMMARY The current evidence consists of low-level studies using mixed aetiology groups, which compromises internal and external validity. There are a few exceptions to this. Poor reporting and heterogeneous methodologies lead to difficulties determining the components of a voice therapy intervention for this population. Consequently, we are unable to evaluate, which intervention elements are beneficial to patients.

Abstract
Importance Microlaryngeal surgery (MLS) is one of the most common procedures in laryngology; however, in cases of postoperative fibrosis, few remedial options are available. Objective To investigate the outcomes of vocal fold steroid injection (VFSI) as an adjuvant treatment for fibrosis after MLS. Design, Setting, and Participants Case series of 228 consecutive patients who underwent MLS for benign vocal lesions between January 2014 and December 2016 at a tertiary medical center. Adjuvant VFSI was performed in 25 patients (11%) with postoperative fibrosis, defined as severely decreased or absent mucosal wave on videolaryngostroboscopy (VLS) lasting for longer than 1 month postoperatively. Data were analyzed from July 1, 2018 to April 30, 2019. Intervention All adjuvant VFSIs were performed in the office under local anesthesia and were repeated monthly if the status of the mucosal wave did not return to normal or mildly decreased on the follow-up VLS. Main Outcomes and Measures The outcome parameters, namely, the 10-item Voice Handicap Index (VHI-10), smoothed cepstral peak prominence (CPP) of recorded voice samples, and mucosal wave status on VLS, were measured before and after MLS and after adjuvant VFSI. Results In this case series of 228 patients (72 men and 156 women; mean [SD] age, 42.8 [12.3] years), 25 had a decreased or absent mucosal wave after MLS, indicating postoperative fibrosis. Of these patients, 22 presented with deep-seated lesions that were removed using a microflap approach. After 1 course of adjuvant VFSI in 17 patients and 2 serial monthly injections in 8 patients, VFSI was associated with improved VHI-10 scores (mean, 24.4 points preoperatively, 22.1 points postoperatively, and 12.9 points after VFSI) that were comparable to the scores of the other 203 patients without vocal fold fibrosis after MLS (mean, 24.8 points preoperatively, 11.7 points postoperatively). Adjuvant VFSI was also associated with improved CPP (mean, 4.04 preoperatively, 4.23 postoperatively, and 5.11 after VFSI) that was comparable to the CPP of the other patients without postoperative fibrosis (mean, 4.33 preoperatively and 5.15 postoperatively). Overall, 19 (76%) of 25 patients with vocal fold fibrosis after MLS had normal (n = 11) or mildly decreased (n = 8) mucosal wave after adjuvant VFSI. Conclusions and Relevance Adjuvant VFSI appeared to be associated with improvements in mucosal wave, voice quality, and subjective perception of dysphonia in patients with fibrosis after MLS, with outcomes comparable to those of the other patients without fibrosis. Adjuvant VFSI may be considered a rescue technique, reducing the rate of fibrosis after MLS from 11% to 3%.
