International Journal of Language &... Jan 2023Pre- and post-operative voice therapy may improve voice and quality-of-life outcomes for patients undergoing phonosurgery to remove benign vocal fold lesions (BVFLs)....
BACKGROUND
Pre- and post-operative voice therapy may improve voice and quality-of-life outcomes for patients undergoing phonosurgery to remove benign vocal fold lesions (BVFLs). However, what constitutes voice therapy in this population is poorly described, resulting in a poor evidence base, lack of clinical guidelines and unwarranted variation in management. In order to develop the evidence base, a robust, iterative process of intervention development work should precede feasibility testing and effectiveness studies.
METHODS & PROCEDURES
Guidance for developing complex interventions, drawing on evidence, theory and modelling, was used to inform the development of a pre- and post-operative voice therapy intervention entitled 'PaPOV'. Data from four sources of evidence were synthesized using a published triangulation protocol. Data from a systematic review, national survey of current practice, expert interview study, and patient and public involvement conversations were used to populate a triangulation matrix, outlining components of a PaPOV. Data were coded to reflect areas of agreement, dissonance and silence with each component of the intervention. Based on this evidence, an assessment of convergence for each intervention component could be made.
OUTCOMES & RESULTS
In total, 61 components of the PaPOV intervention were explored. Of these, 27 were categorized as having stability of consensus according to a priori criteria. A total of 34 failed to meet the criteria. This was more frequently due to silence (27) rather than dissonance (seven) in the data. By evidencing areas of agreement and stability of consensus across data sources, the validity of individual findings has been enhanced. Furthermore, the study has exposed specific areas of the intervention that lack consensus and require exploration through further intervention development studies.
CONCLUSIONS & IMPLICATIONS
This systematic triangulation process has contributed to the development of a PaPOV intervention for patients with BVFLs. Exploration of specific components relating to the intervention will allow outstanding questions to be answered in preparation for feasibility testing.
WHAT THIS PAPER ADDS
What is already known on the subject BVFLs cause dysphonia by preventing vocal fold closure, impacting on vibratory characteristics and increasing compensatory muscle tension. Management for these patients is variable with them being offered phonosurgery, voice therapy, pharmacological management or a combined approach. Pre- and post-operative voice therapy may improve both voice and quality-of-life outcomes. This patient group has unique complexities when considering voice therapy, including surgical preparation, wound healing and epithelial mobilization. What this paper adds to existing knowledge This study uses a robust triangulation process to synthesize current evidence and patient experiences in order to inform the development of a PaPOV. It outlines some of the key components and considerations when delivering pre- and post-operative voice therapy to adults with BVFLs. Furthermore, it serves as a methodological example for intervention development in complex interventions, highlighting key guidance and recommended processes for developing and evaluating complex interventions. What are the potential or actual clinical implications of this work? The 61 components discussed as potential 'ingredients' for a PaPOV enable clinicians to reflect on key considerations when planning and delivering voice therapy to adults with BVFLs. This study highlights the pitfalls both clinically and in research of failing to describe interventions adequately and the benefits of using accurate, specific and agreed terminology in clinical practice, such as that outlined in the Rehabilitation Treatment Specification System (TRSS).

Meta-Analysis
PURPOSE
Recurrent laryngeal nerve (RLN) injury is a feared complication of thyroid surgery occurring in 1-5% of cases. The present approaches to RLN preservation include RLN visualization with no nerve monitoring (No-NM), intermittent intra-operative nerve monitoring (I-IONM) and continuous intra-operative nerve monitoring (C-IONM). There is ambiguity as to which of these strategies should be the preferred method of RLN preservation.
METHODS
A systematic review of the PubMed, Embase and the Cochrane Collaboration databases was undertaken with network meta-analysis (NMA) performed according to the PRISMA and Cochrane Collaboration guidelines. A Bayesian NMA was conducted using R packages netmeta with outcomes expressed as odds ratios (ORs) with 95% credible intervals (CrI). Only prospective studies were included.
RESULTS
Eighteen studies met inclusion criteria, including 22,080 patients and 40,642 nerves at risk (NAR). Overall, 23,364 NARs (57.5%) underwent I-IONM, 17,176 (42.3%) No-NM and 98 (0.2%) underwent C-IONM. There were no significant differences between groups regarding the incidence of permanent RLN injury following thyroid surgery (I-IONM vs.No-NM, OR 0.84, 95% CrI 0.55-1.19; C-IONM vs. No-NM, OR 0.44, 95% CrI 0.02-5.00). Pooled analysis showed that IONM (I-IONM or C-IONM) demonstrated a protective effect versus No-NM in reducing the incidence of transient RLN injury (OR 0.75, 95% CI 0.59-0.97, p = 0.03).
CONCLUSIONS
IONM strategies did not significantly reduce the incidence of permanent RLN injury following thyroid surgery. However, the small number of C-IONM NARs limits conclusions that may be drawn. Further well-designed prospective studies will be required to definitively assess the utility of C-IONM.

Review
OBJECTIVE
The larynx is the most common site of localized head and neck amyloidosis. Our study aimed to review the clinical features, treatments, and outcomes associated with localized laryngeal amyloidosis (LA). We also compared these features between two different time periods to evaluate the evolution of LA management.
METHODS
A literature search using PubMed, CINAHL, Embase, and Cochrane Library identified cases of LA published between 1891 and 2021. Biopsy-proven cases of localized LA were included. Non-English studies, animal studies, and reviews were excluded.
RESULTS
282 patients (1891-1999: 142 patients, 2000-2021: 140 patients) from 129 studies were included. Results are reported as 1891-2000 vs. 2000-2021: Mean age was 48.5 years (range, 8-90 years) vs. 46.0 years (range, 9-84 years). The most common presenting symptoms were dysphonia (n = 30, 95 % vs. n = 127, 96 %) and difficulty breathing (n = 37, 27 % vs. n = 35, 27 %). A total of 62 (44 %) vs. 46 (33 %) lesions were found in the true vocal folds and 35 (25 %) vs. 59 (42 %) were found in the false vocal folds. 133 (94 %) vs. 137 (98 %) patients underwent surgical interventions to investigate and/or treat LA. Recurrent LA was reported in 27 (19 %) vs. 33 (24 %) patients with a mean time to recurrence of 25.4 months (range, 0.3-132 months) vs. 34.5 months (range, 0.8-144 months). Of cases reporting survival rate, 104 (97 %) vs. 107 (99 %) were alive at source study endpoints.
CONCLUSION
LA typically exhibits an indolent course; therefore, early intervention may address longstanding symptoms. Recurrent disease poses a clinical challenge in patients with LA.

Meta-Analysis
OBJECTIVE
This systematic review aims to provide an overview of the current evidence-base for paediatric surgical reinnervation in unilateral and bilateral vocal fold palsies in clinical practice. We aim to assess patient demographics, surgical technique and pre- and post-operative outcome measures.
METHODS
A systematic literature review was performed and reported according to international PRISMA recommendations. A comprehensive search of PubMed, Embase, and Cochrane CENTRAL databases for relevant publications for all available dates with appropriate MESH search criteria was performed. Articles were categorised by four authors independently. A pooled summative analysis was carried out to allow review of demographic and outcome data.
RESULTS
Our systematic PRISMA approach resulted in 19 papers being selected for inclusion and analysis with 179 patients undergoing reinnervation (153 unilateral, 26 bilateral). The youngest patient was 1.9 years. Iatrogenic injury to recurrent laryngeal nerve most common aetiology (65.4% and 19.2% of unilateral and bilateral vocal fold palsies, respectively). Patent ductus arteriosus ligation was the single most common procedure resulting in unilateral vocal fold palsies (43.1% of cases). Statistically significant improvements in subjective and objective outcomes for both voice and swallowing were seen. Meta-analysis was able to be performed on the particularly evident improvements in GRBAS score and Maximum Phonation Time (MPT). GRBAS scores improved by 3.64 (p < 0.01, 95% CI 2.65 to 4.63). MPT showed a statistically significant improvement of 5.26 s (p < 0.05, 95% CI 4.28 to 6.24). No major complications were reported.
CONCLUSION
The current published evidence on one-hundred and seventy-nine paediatric surgical reinnervation procedures demonstrates its role as a safe and effective treatment for both unilateral and bilateral vocal fold palsies. Anatomically it has been shown to improve vocal fold tone, bulk and position. Both post-operative voice and swallowing outcomes show improvement as well as associated quality of life measures.

Review
BACKGROUND
Many transgender women and men undergo gender-affirming surgeries. Existing work shows that early surgery outcomes are generally positive, suggesting high surgical satisfaction and positive quality of life outcomes. Less work, however, examines these outcomes in the longer-term.
AIMS
To conduct a systematic literature review into the longer-term (i.e., ≥ 1 year) surgical satisfaction and quality of outcomes following various forms of gender-affirming surgery in transgender populations. Specifically, we aim to examine research on such outcomes at least one-year post gender-affirming chest, genital, facial, vocal cord, and Adam's apple removal surgeries.
METHODS
Studies were identified through Google Scholar, PsycINFO, Scopus, and PubMed databases, as well as through Google Scholar search alerts. We considered all studies published until October 2021. Two reviewers extracted data from suitable studies using Covidence. Both reviewers also independently assessed the identified studies' risk of bias and strength of evidence.
RESULTS
Seventy-nine low quality (e.g., small sample sizes, lack of control/comparison groups) studies suggest that most transgender patients are satisfied with surgical outcomes when assessed at least one-year post-surgery. Low quality research also indicates that transgender women and men typically report positive psychological and sexual wellbeing post-surgery, and similar wellbeing outcomes as those who have not had surgery.
DISCUSSION
To the best of our knowledge, this literature review is the first to critically summarize and evaluate all published studies on the longer-term quality of life outcomes following chest, genital, facial, voice and Adam's apple removal surgeries for transgender women and men. While the results suggest promising surgical satisfaction and quality of life outcomes following surgery, many studies only draw on small samples, and most studies do not allow for causal conclusions. Further, few studies have compared surgical outcomes between transgender women and men. We conclude by offering concrete suggestions for future research.

Review
BACKGROUND
Glottal insufficiency, mostly caused by unilateral vocal fold paralysis (UVFP) or vocal fold atrophy can be treated by injection laryngoplasty (IL). Materials such as hyaluronic acid (HA) gels are now widely available and used to improve voice quality. Various durability and effects of HA injection laryngoplasties have been reported. The aim of this study is to provide a systematic review of the literature for the use of HA in injection laryngoplasties.
METHODS
A systematic literature search was conducted in PubMed and Cochrane Libraries. Three reviewers assessed original research studies concerning vocal fold augmentation with HA for eligibility. English written full-text human studies from 2000 to 2020 with EBM level 1b-2 were included. In vitro studies, animal studies, case reports, case-control studies, correspondence and review articles, and articles with other injection materials were excluded. Demographical data, indication, type of HA, evaluation methods, follow-up, durability of implanted material and complications were assessed.
RESULTS
A total number of 311 articles were found in PubMed and Cochrane Library, 13 studies were eligible for final analysis with 1063 patients, mean age of patients was 58.7 years. Main indication for HA IL was unilateral vocal fold paralysis, evaluation methods were subjective-VHI (Voice Handicap Index) questionnaire and objective-acoustic and aerodynamic measurements, mean time of follow-up was 5.9 months. Large-particle HA gels were more favorable for longer durability than small-particle HA, reported time of resorption of HA gels ranges between 6 and 12 months, and complication rate was low.
CONCLUSION
Hyaluronic acid injection laryngoplasty increases voice quality, improves results of voice therapy, and can be recommended as overlap treatment before permanent medialization surgery. Compared to other injected materials, HA seems to have more favorable effect on vibratory functions of the vocal folds and thus on the voice quality parameters.

International Journal of Language &... Nov 2022Vocal fold nodules (VFNs) are the main cause of paediatric dysphonia. Voice therapy is recommended as the preferable treatment option for VFNs in children. (Review)
Review
BACKGROUND
Vocal fold nodules (VFNs) are the main cause of paediatric dysphonia. Voice therapy is recommended as the preferable treatment option for VFNs in children.
AIM
The aim of this systematic review is to provide an overview of the existing literature concerning the effects of voice therapy in children with VFNs.
METHODS & PROCEDURES
This systematic literature review was developed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (via PubMed) and Embase were searched and the grey literature was checked. The search strategy was based on three concepts: VFNs, voice therapy and children. Two examiners independently determined article eligibility and extracted all relevant data from the included studies. The methodological quality of the included study was assessed using the QualSyst tool.
MAIN CONTRIBUTIONS
By identifying, evaluating and summarizing the results of all relevant studies about voice therapy in paediatric VFNs, this systematic review makes the available evidence more accessible to voice therapists, otolaryngologists and other relevant stakeholders.
CONCLUSIONS & IMPLICATIONS
24 studies were included in this systematic review. Eight studies (8/24) reported a significant improvement for at least one outcome parameter after voice therapy. However, five papers (5/24) could not demonstrate significant changes after voice therapy. All studies that did not test for significance (11/24) found improvements for one or more outcome parameters. The overall quality of the included studies is adequate (55%). In sum, there is some evidence that voice therapy is effective in children with VFNs, but further well-designed research, especially randomized controlled trials, is necessary to confirm these results.
WHAT THIS PAPER ADDS
What is already known on the subject Voice therapy is preferable in children with VFNs because of the phonotraumatic nature of the nodules and the associated high recurrence rate after phonosurgery. Most voice therapists in clinical practice offer an eclectic voice therapy programme, consisting of direct and indirect voice therapy techniques. What this study adds to existing knowledge This systematic review provides a clear overview of the available evidence concerning the effects of voice therapy in paediatric VFNs. There is some evidence that voice therapy is an effective treatment option in children with VFNs, but well-designed research is scarce on this subject. What are the potential or actual clinical implications of this work? This review shows that effectiveness studies with strong designs are very scarce in children with VFNs. Clinicians should be aware that few therapy techniques have been thoroughly investigated in this population. However, this review may guide voice therapists when creating a treatment plan for a child with VFNs because it identifies, evaluates and summarizes the results of all relevant individual studies about voice therapy in paediatric VFNs. Voice therapy seems to be effective in treating paediatric patients with VFNs, given the fact that a considerable number of included studies report significant improvements after voice therapy. Both direct and indirect therapy approaches appear to have a positive effect on the phonation of children with VFNs.

OBJECTIVES
This meta-analysis evaluated the short-term safety and efficacy of indocyanine green (ICG) fluorescence in gastric reconstruction to determine a suitable anastomotic position during esophagectomy.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyzes 2020 (PRISMA) were followed for this analysis.
RESULTS
A total of 9 publications including 1,162 patients were included. The operation time and intraoperative blood loss were comparable in the ICG and control groups. There was also no significant difference in overall postoperative mortality, reoperation, arrhythmia, vocal cord paralysis, pneumonia, and surgical wound infection. The ICG group had a 2.66-day reduction in postoperative stay. The overall anastomotic leak (AL) was 17.6% (n = 131) in the control group and 4.5% (n = 19) in the ICG group with a relative risk (RR) of 0.29 (95% CI 0.18-0.47). A subgroup analysis showed that the application of ICG in cervical anastomosis significantly reduced the incidence of AL (RR of 0.31, 95% CI 0.18-0.52), but for intrathoracic anastomosis, the RR 0.35 was not significant (95% CI 0.09-1.43). Compared to an RR of 0.35 in publications with a sample size of <50, a sample size of >50 had a lower RR of 0.24 (95% CI 0.12-0.48). Regarding intervention time of ICG, the application of ICG both before and after gastric construction had a better RR of 0.25 (95% CI 0.07-0.89).
CONCLUSIONS
The application of ICG fluorescence could effectively reduce the incidence of AL and shorten the postoperative hospital stay for patients undergoing cervical anastomosis but was not effective for patients undergoing intrathoracic anastomosis. The application of ICG fluorescence before and after gastric management can better prevent AL.

IMPORTANCE
Button batteries (BBs) are commonly found in many household items and present a risk of severe injury to children if ingested. The direct apposition of the trachea and recurrent laryngeal nerves with the esophagus puts children at risk of airway injury secondary to the liquefactive necrotic effects of BB impactions.
OBJECTIVE
To review airway injuries, including long-term sequelae, after BB ingestion in children.
EVIDENCE REVIEW
For this systematic review, a comprehensive strategy was designed to search MEDLINE, Embase, Cochrane Database of Systematic Reviews, Web of Science, and CINAHL (Cumulative Index of Nursing and Allied Health Literature) from inception to July 31, 2021, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Additional cases were identified from the National Capital Poison Center BB registry. Individual authors were contacted for additional information. Studies with pediatric patients (<18 years) who developed airway injuries after BB ingestion were included. A total of 195 patients were included in the analysis; 95 were male. The mean (SD) age at BB ingestion was 17.8 (10.2) months. The mean (SD) time from BB ingestion to removal was 5.8 (9.0) days. The 2 most common airway sequelae observed in our series were 155 tracheoesophageal fistulae and 16 unilateral vocal cord paralyses. Twenty-three children had bilateral vocal cord paralysis. The mean (SD) duration of ingestion leading to vocal cord paralysis was shorter than that of the general cohort (17.8 [22.5] hours vs 138.7 [216.7] hours, respectively). Children presenting with airway symptoms were likely to have a subsequent tracheoesophageal fistula or vocal cord paralysis.
CONCLUSIONS AND RELEVANCE
Airway injuries are a severe consequence of BB ingestion, occurring more often in younger children. This systematic review found that tracheoesophageal fistulae and vocal cord paralyses were the 2 most common airway injuries, often requiring tracheostomy. Vocal cord injury occurred after a shorter BB exposure time than other airway injuries. Continued efforts should be directed toward prevention strategies to avoid the devastating sequelae of BB-associated airway injury.

Meta-Analysis
IMPORTANCE
Papillary thyroid microcarcinomas (PTMCs) have been associated with increased thyroid cancer incidence in recent decades. Total thyroidectomy (TT) has historically been the primary treatment, but current guidelines recommend hemithyroidectomy (HT) for select low-risk cancers; however, the risk-benefit ratio of the 2 operations is incompletely characterized.
OBJECTIVE
To compare surgical complication rates between TT and HT for PTMC treatment.
DATA SOURCES
SCOPUS, Medline via the PubMed interface, and the Cochrane Central Register of Controlled Trials (CENTRAL); through January 1, 2021, with no starting date restriction. Terms related to papillary thyroid carcinoma and its treatment were used for article retrieval. This meta-analysis used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline and was written according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) proposal.
STUDY SELECTION
Original investigations of adults reporting primary surgical treatment outcomes in PTMC and at least 1 complication of interest were included. Articles evaluating only secondary operations or non-open surgical approaches were excluded. Study selection, data extraction, and risk of bias assessment were performed by 2 independent reviewers and conflicts resolved by a senior reviewer.
DATA EXTRACTION AND SYNTHESIS
Pooled effect estimates were calculated using a random-effects inverse-variance weighting model.
MAIN OUTCOMES AND MEASURES
Cancer recurrence and site, mortality (all-cause and disease-specific), vocal fold paralysis, hypoparathyroidism, and hemorrhage/hematoma. Risk of bias was assessed using the McMaster Quality Assessment Scale of Harms scale.
RESULTS
In this systematic review and meta-analysis, 17 studies were analyzed and included 1416 patients undergoing HT and 2411 patients undergoing TT (HT: pooled mean [SD] age, 47.0 [10.0] years; 1139 [84.6%] were female; and TT: pooled mean [SD] age, 48.8 [10.0] years; 1671 [77.4%] were female). Patients undergoing HT had significantly lower risk of temporary vocal fold paralysis compared with patients undergoing TT (3.3% vs 4.5%) (weighted risk ratio [RR], 0.4; 95% CI, 0.2-0.7), temporary hypoparathyroidism (2.2% vs 21.3%) (weighted RR, 0.1; 95% CI, 0.0-0.4), and permanent hypoparathyroidism (0% vs 1.8%) (weighted RR, 0.2; 95% CI, 0.0-0.8). Contralateral lobe malignant neoplasm recurrence was 2.3% in the HT group, while no such events occurred in the TT group. Hemithyroidectomy was associated with a higher overall recurrence rate (3.8% vs 1.0%) (weighted RR, 2.6; 95% CI, 1.3-5.4), but there was no difference in recurrence in the thyroid bed or neck.
CONCLUSIONS AND RELEVANCE
The results of this systematic review and meta-analysis help characterize current knowledge of the risk-benefit ratio of HT vs TT for treatment of PTMC and provide data that may have utility for patient counseling surrounding treatment decisions.
