Abstract
OBJECTIVE Analyze the duration of symptom-free intervals following laser wedge excision (LWE) for recurrent idiopathic subglottic stenosis (iSGS). Secondary aim includes evaluating the influence of patient-related or disease factors. STUDY DESIGN Retrospective review. SETTING Tertiary center. METHODS Review of iSGS patients who underwent LWE between 2002 and 2021. LWE patients without prior airway surgery were labeled LWE primary (LWEP) and those with prior history of dilation were labeled LWE secondary (LWES). A conditional frailty repeated events model was used to analyze the median time to recurrence (MTR) for each nth recurrence. Secondary analysis included stratification by use of medical therapy and initial preoperative characteristics of scar (Myer-Cotton grade, distance between the glottis and superior-most aspect of scar, DGS; length of scar, DL). RESULTS Two hundred and ten iSGS patients underwent LWE (131 LWEP, 79 LWES). The proportion of patients experiencing at least 1, 3, 6, and 12 recurrences, respectively, was 68.0% (n = 143), 40.7% (n = 85), 20.0% (n = 42), and 5.2% (n = 11). There was exponential time-shortening from the 1st to 12th recurrence (P < .0001). While MTR was 4.1 years after the first LWE, this fell to 2.8, 1.7, 1.0, and 0.7 years for the 2nd, 3rd, 6th, and 12th recurrences. Furthermore, LWEP patients experienced longer MTR than LWES counterparts within the first 6 recurrences (P < .01). There was no significant relationship between intersurgical interval and medication adherence, DL, DGS, or grade for recurrences beyond the first (P = .207, P = .20, P = .43, P = .16). CONCLUSION Symptom-free intervals in iSGS shorten with each subsequent recurrence and LWE. The difference in MTR between LWEP and LWES groups was significant within the first 6 recurrences with LWEP having longer MTR. LEVEL OF EVIDENCE: 3

Abstract
Objective To characterize presentation, disease course, and treatment of idiopathic subglottic stenosis (iSGS) in non-Caucasian women and compare this cohort to the predominantly female, Caucasian patient cohorts identified in the literature. Study Design Retrospective review. Results are compared to systematic review of demographics. Setting Multiple California institutions from 2008 to 2021. Methods Patients with intubation within 2 years of disease or who met exclusion criteria listed in prior publications were excluded. A systematic review of iSGS patient demographics was also completed for comparison. Results Of 421 patients with iSGS, 58 self-identified as non-Caucasian women, with 50 ultimately included. Mean age of onset was 45.1 years old (95% confidence interval [CI], 41.5-48.8), and mean age at diagnosis was 47.2 years (95% CI, 43.6-50.7). Mean Charlson comorbidity index was 1.06 (n = 49, 95% CI, 0.69-1.44). At diagnosis, Cotton-Meyer severity scores (documented in n = 45) were Cotton-Myer (CM) I (28.9%), CM II (40%), and CM III (31.1%). Mean age at first endoscopic surgery was 47.7 (95% CI, 44.2-51.3) years. 64% experienced disease recurrence with a median of 11 months between their first and second surgery. Our systematic review identified 60 studies that reported demographic features in patients with iSGS. 95% of pooled patients were Caucasian, while other demographic features were similar to the current cohort. Conclusion The non-Caucasian population, almost 14% of this Californian cohort, does not differ from the majority Caucasian population detailed in contemporary literature. This cohort supports the presence of some racial and ethnic heterogeneity in this disease population.

Abstract
OBJECTIVES The management of idiopathic subglottic stenosis (iSGS) poses a clinical challenge due to high recurrence rates following both endoscopic and open approaches, often leading to tracheostomy. The activation of abnormal T-cells and cytokine pathways has been linked to iSGS pathogenesis. Autologous adipose tissue centrifugation yields lipoaspirate, offering optimal anti-inflammatory effects and biocompatibility widely utilized in various medical settings. This report presents the first 3 cases employing endoscopic dilation (ED) in combination with local lipoaspirate injection to address recurrent iSGS. METHODS A prospective observational study was conducted, involving multidisciplinary evaluation by the Tracheal Team at the University of Modena. Patients meeting specific criteria were directed to undergo ED + lipoaspirate injection. RESULTS Three patients fulfilled the inclusion criteria. The mean number of prior endoscopic procedures performed was 8. Endoscopic examination revealed 90% stenosis in patient A, 60% stenosis in patient B, and 60% stenosis in patient C. All patients presented inflammatory tissue or incipient granulations at the stenotic site, with an average time of 6 months between previous procedures. After 15 months, none of the patients required further procedures, and endoscopic examination revealed a significant reduction or disappearance of inflammatory tissue with a stable airway lumen. CONCLUSIONS The observed results are encouraging in terms of reducing local inflammation and halting stenosis progression, especially in cases of short-term relapsing iSGS.

Abstract
OBJECTIVES Airway reconstruction for laryngo tracheal stenosis (LTS) improves dyspnoea. There is little evidence relating to impact upon voice and swallowing. We explored voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. DESIGN Outcome measures were collected pre-reconstructive surgery, two-weeks post-surgery and up to 4-6 months post-surgery. SETTING Tertiary referral centre. PARTICIPANTS With ethical approval, twenty consecutive adult (≥18 years) LTS patients undergoing airway reconstruction were prospectively recruited. MAIN OUTCOME MEASURES These included physiological values (maximum phonation time (MPT) and fundamental frequency; penetration aspiration score, residue score), clinician-reported (GRBAS, functional oral intake score, 100ml Water Swallow Test) and patient-reported outcomes (Voice Handicap Index-10, Reflux Symptoms Index, Eating Assessment Tool, Dysphagia Handicap Index). RESULTS The observational study identified patient-reported and clinician-reported voice and swallow difficulties pre- and post-surgery; median and interquartile range are reported at each time point: Voice Handicap Index-10 23 (8-31); 20.5 (9-33.5), 24.5 (12.5-29); Dysphagia Handicap Index 9 (0-37); 13 (7-44); 15 (4-34); GRBAS grade 1(1-2); 2 (1-2.5); 2(1-2); 100ml Water Swallow Test volume score 16.7 (11.1-20); 14.3 (12.5-16.7); 16.7 (14.3-20.0); 100ml Water Swallow Test capacity score 16.3 ± 9.0; 11.0 ± 4.1; 12.5 ± 2.6. CONCLUSIONS We present the first prospective data on voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. The variability of the outcomes was higher than expected but importantly, for many the voice and swallow outcomes were not within normal limits before surgery. The clinical value of the study demonstrates the need for individual assessment and management of LTS patients' voice and swallowing.

Abstract
INTRODUCTION Subglottic and tracheal stenosis (SGTS) in adults is an acquired or idiopathic condition that can lead to dyspnea, and even life-threatening airway obstruction. Endoscopic techniques have advanced and largely eclipsed open surgery, with open surgery now reserved for refractory cases (Hseu et al., 2013; Feinstein et al., 2017). Currently, there is no accepted guideline for the endoscopic treatment of SGTS. Thus, the aim of the present study is to examine the impact of various clinical and pathological characteristics on outcomes to endoscopic treatment in a cohort of SGTS patients. DISCLOSURE None of the authors have any financial or personal relationship that could cause a conflict of interest regarding this article. METHODS Retrospective chart review was performed for 41 patients presenting with SGS without a tracheostomy over a 4-year-period (2018-2022), within a single tertiary care center. Quantitative outcomes including number of dilation procedures undergone and need for open procedures were examined. The qualitative variables included a history of pulmonary disease, prior tracheostomy/tracheal resection, presence of tracheomalacia, granulation tissue, excessive dynamic airway collapse (EDAC), and etiology of idiopathic subglottic stenosis. RESULTS The presence of granulation tissue seen on tracheoscopy was associated with a higher number (4+) of dilation procedures (p = 0.01). A history of pulmonary disease (p = 0.037), the presence of tracheomalacia (p = 0.039), and the presence of granulation tissue (0.003) were all associated with a need for open procedures. CONCLUSION Patients with the presence of granulation tissue, tracheomalacia, and a history of pulmonary disease were more associated with more severe disease requiring either a higher number of endoscopic procedures or need for open procedures.

Abstract
OBJECTIVES Repeat endoscopic dilation (ED) in the operating room for subglottic stenosis (SGS) remains an economic burden to patients. The cost-effectiveness (CE) of adjuvant serial intralesional steroid injections (SILSI) to prolong the surgery-free interval (SFI) in SGS patients requiring ED has yet to be studied. METHODS Details of the cost of SILSI and ED were received from our tertiary academic center. SFI, cost of intervention, and the effect of SILSI on prolonging SFI were collected from a systematic review by Luke et al. SGS etiologies in the review included idiopathic, iatrogenic, or autoimmune. A break-even analysis, comparing the cost of SILSI alone with the cost of repeat ED, was performed to determine if SILSI injections were cost-effective in prolonging the SFI. RESULTS Average extension of the SFI with SILSI was an additional 219.3 days compared to ED alone based on a systematic review of the literature. 41/55 (74.5%) cases did not require further ED once in-office SILSI management began. SILSI administered in a 4-dose series in 3-to-7-week intervals (~$7,564.00) is CE if the reported recurrence rate of SGS requiring ED (~$39,429.00) has an absolute risk reduction (ARR) of at least 19.18% with the use of SILSI. Based on the literature, SILSI prevents ~3 out of every 4 cases of SGS at sufficient follow-up from undergoing repeat ED, resulting in an ARR of ~75%. CONCLUSIONS SILSI is economically reasonable if it prolongs the SFI of at least one case of recurrence out of 5. SILSI, therefore, can be CE in extending the interval for surgical ED.

Abstract
OBJECTIVES Idiopathic subglottic stenosis (iSGS) is characterized by progressive fibrosis and subglottic luminal narrowing. Currently, immune characterization has focused on T-cells; however, macrophages remain largely unexplored. The goals of this study are to characterize the transcriptome of iSGS macrophages and the fibrogenic nature of identifed biomarkers. STUDY DESIGN Bioinformatics and in vitro. METHODS Human tracheal biopsies from iSGS scar (n = 4), and matched non-scar (n = 4) regions were analyzed using single-cell RNA-seq (scRNA-seq). Immunofluorescence (IF) was performed on rapidly processed autopsies (RPA) and iSGS tracheal resections (n = 4) to co-localize S100A8/9 and CD11b. Collagen gene/protein expression was assessed in iSGS fibroblasts (n = 4) treated with protein S100A8/9 (1000 ng/ml). Macrophages were subclustered to identify distinct subpopulations. RESULTS scRNA-seq analysis revealed S100A8/S100A9 (fold change (FC) = 4.1/1.88, p < 0.001) as top differentially expressed genes in iSGS macrophages. IF exhibited increased CD11b+/S100A8/9+ cells in tracheal samples of iSGS versus RPA (26.75% ± 7.08 vs. 0.594% ± 0.974, n = 4, p = 0.029). iSGS fibroblasts treated with S100A8/9 demonstrated increased gene expression of COL1A1 (FC = 2.30 ± 0.45, p = 0.03, n = 4) and COL3A1 (FC = 2.44 ± 0.40, p = 0.03, n = 4). COL1A1 protein assays revealed an increase in the experimental group, albeit not significant, (p = 0.12, n = 4). Finally, macrophage sub clustering revealed one subpopulation as a predominant source of S100A8/S100A9 expression (FC = 7.94/5.47, p < 0.001). CONCLUSIONS S100A8/9 is a key biomarker in iSGS macrophages. Although S100A8/9 demonstrates profibrotic nature in vitro, the role of S100A8/9+ macrophages in vivo warrants further investigation. LEVEL OF EVIDENCE NA Laryngoscope, 133:2308-2316, 2023.

INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2023; 58:376-389. [PMID: 36189991 DOI: 10.1111/1460-6984.12794] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Accepted: 09/09/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Acquired laryngotracheal stenosis (LTS) is a rare condition that causes breathlessness and dyspnoea. Patients have reconstructive airway surgery to improve their breathing difficulties, but both LTS and the surgery can cause voice difficulties. The existing evidence base for management of voice difficulties for adults with LTS focuses on symptoms. There is limited information to provide clinical guidance for speech and language therapists (SLTs) and a limited understanding of the impact of voice changes on adults with LTS. AIM To investigate the lived experience of adults with laryngotracheal stenosis (LTS), who have had reconstructive surgery; here focussing on voice concerns with the aim of guiding clinical care for SLTs. METHODS AND PROCEDURES A phenomenological, qualitative study design was used. Focus groups and semi-structured interviews were completed with adults living with LTS who had had reconstructive surgery. Audio recordings were transcribed and inductive thematic analysis was used by the research team to identify themes and sub-themes. OUTCOMES AND RESULTS A total of 24 participants (five focus groups and two interviews) took part in the study before thematic saturation was identified in analysis. Three main themes were identified specific to the experience of living with LTS: the Medical, Physical and Emotional journey. All participants referenced voice difficulties as they related to each of these overall themes. Sub-themes directly related to voice included experience of surgery, information provision, staff expertise/complacency, symptoms, symptom management, identity, support networks, impact on life and living with a chronic condition. CONCLUSIONS AND IMPLICATIONS In this qualitative study participants have described the integral part voice difficulties play in their lived experience of LTS and reconstructive surgery. This is considered in the context of their clinical care and the need for individualised management and information provision throughout the course of their condition. The broader research literature relating to voice difficulties is explored with links made to people with LTS and recommendations made for future research into people living with LTS and dysphonia. WHAT THIS PAPER ADDS What is already known on this subject Adults with laryngotracheal stenosis (LTS) experience voice changes as a result of their condition, and the surgeries necessary as a treatment. These changes can lead to altered pitch, vocal fatigue, loss of pitch range and loss of volume control. Although there are known psychosocial implications both to living with a chronic condition and voice difficulties there has been no research exploring this in adults with LTS, and there is minimal clinical guidance for speech and language therapists (SLTs) working with these patients. What this paper adds to existing knowledge This research is the first study to explore the lived experience of adults with LTS who undergo reconstructive surgery, focusing on their voice concerns. This study demonstrates the multifactorial impacts of voice changes on all aspects of the lives of adults with LTS and the need for individualised information provision and clinical care to help support them. What are the potential or actual clinical implications of this work? Adults with LTS want expert SLTs to facilitate their care and support them throughout their LTS journey alongside other support networks. They want to be carefully prepared for reconstructive surgery and given clear information about symptoms and management of their voice difficulties. This has led to the reorganisation of the care pathway at our centre, and the introduction of a patient-led pretreatment session.

Abstract
PURPOSE Our previous study on the idiopathic progressive subglottic stenosis (IPSS) highlighted a possible hormonal mechanism, with over-expression of estrogen receptors alpha (ER-α) and progesterone receptors (PR). We tested whether such over-expression take place in non-idiopathic subglottic stenosis (NISS) as well. METHODS 37 specimens of iatrogenic NISS were analyzed (20 females; mean age, 59 ± 12 years; range 41-85). Immunoreactivity of ER-α and PR was calculated as the product of intensity (1 = weak, 2 = moderate, 3 = strong) and positive cells percentage (1 to 4, for < 10%, 10-50%, 50-80%, and > 80%). This score was calculated on the stenotic tissue (ST), and stenosis margins (SM). RESULTS The expression of PR was significantly higher in ST of IPSS compared with female and male NISS patients (8.7 ± 3.1 vs. 4.9 ± 3.2, p < 0.001 for IPSS vs. female and 8.7 ± 3.1 vs. 2.1 ± 2.7, p < 0.01 for IPSS vs. male NISS patients). Contrarily, ER-α showed gender differences, as both IPSS and female NISS patients had similar, yet higher ER-α expression compared with male NISS patients (7.0 ± 4.2 vs. 6.5 ± 2.5, p = NS for IPSS vs. female and 7.0 ± 4.2 vs. 3.4 ± 2.0, p < 0.02 for IPSS vs. male NISS patients). There was no difference in fibroblast receptor expression between ST and SM. However, ER-α and PR expression was significantly lower in marginal mucous glands when compared with ST. CONCLUSIONS The IPSS pathogenesis appears to be driven by hormonal mechanisms, in particular, by over-expression of PR. Marginal cells display a reduced hormone receptor density. This finding could be interpreted as a compensatory mechanism. These findings could open up for targeted IPSS treatment.

Abstract
An 8-year-old girl presented with treatment-refractory cough and inspiratory stridor. Bronchoscopies showed progressive scarring leading to narrowing of the proximal trachea (Myer-Cotton Grade 2) and epithelial metaplasia of the tracheal and bronchial mucosa. After excluding other causes of congenital and acquired tracheal stenosis, an idiopathic subglottic tracheal stenosis (iSGS) was diagnosed. Because of the patient's young age, a judicious therapeutic approach seemed appropriate. Therapy with azithromycin, followed by roxithromycin, was started. Symptoms almost completely subsided, spirometry normalized, and endoscopic and histologic findings improved considerably. Therapy has been continued for more than 3 years with normal lung function values, and no compromise on physical activities and development. In instances of iSGS, therapy with macrolides is worth considering before more invasive procedures such as dilatation, laser, intralesional injections, or surgical resection are performed.

Abstract
Objectives In-office serial intralesional steroid injections (SILSIs) have become a commonly used treatment for subglottic stenosis. We characterized the impact of SILSIs on the time between operating room visits and incidence of glucocorticoid systemic side effects. Study Design Retrospective case series. Setting Academic tertiary care center. Methods All patients with subglottic stenosis receiving SILSIs at 1 institution from 2016 to 2020 were included. Surgery-free interval was compared using paired t tests. Side effect incidence was calculated with Kaplan-Meier methodology for visualization. Results Nineteen patients and 207 procedures were included. The majority of patients were White (95%) and female (95%) and had idiopathic subglottic stenosis (53%). Mean surgery-free interval for all patients was 8.7 months (95% CI, 5.6-11.8) before initiating SILSIs. Of 11 patients with calculable surgery-free interval, 10 experienced improvement, with a mean surgery-free interval increase of 4.6 months (95% CI, 2.4-6.7). Seven patients have not required surgery since initiation of SILSIs, with a mean follow-up time of 28 months (95% CI, 25-31). Noncutaneous systemic side effects occurred at a mean 3.2 months (95% CI, 2.4-4.0) from first injection and included Cushing’s syndrome, increased intraocular pressure, central serous chorioretinopathy, and new insulin requirement in the setting of diabetes. Conclusions Ninety-one percent of patients who initiated SILSIs and had a subsequent return to the operating room experienced a mean 4.6-month increase in surgery-free interval. Systemic side effects of glucocorticoids occurred in 32% of patients after initiating SILSIs. This should be considered in preprocedure counseling and side effect monitoring during treatment.

Abstract
Objectives: To investigate how the symptoms of mucus and cough impact adults living with laryngotracheal stenosis, and to use this information to guide future research and treatment plans. Methods: A survey was developed with the support of patient advisors and distributed to people suffering with laryngotracheal stenosis. The survey comprised 15 closed and open questions relating to mucus and cough and included the Leicester Cough Questionnaire (LCQ). Descriptive statistics, X2 and thematic analyses were completed. Results: In total, 641 participants completed the survey, with 83.62% (n = 536) reporting problems with mucus; 79% having daily issues of varying severity that led to difficulties with cough (46.18%) and breathing (20.90%). Mucus affected voice and swallowing to a lesser degree. Respondents described a range of triggers; they identified smoky air as the worst environmental trigger. Strategies to manage mucus varied widely with drinking water (72.26%), increasing liquid intake in general (49.35%) and avoiding or reducing dairy (45.32%) the most common approaches to control symptoms. The LCQ showed a median total score of 14 (interquartile range 11-17) indicative of cough negatively affecting quality of life. Thematic analysis of free text responses identified 4 key themes—the Mucus Cycle, Social impact, Psychological impact, and Physical impact. Conclusion: This study shows the relevance of research focusing on mucus and cough and its negative impact on quality of life, among adults with laryngotracheal stenosis. It demonstrates the inconsistent advice and management strategies provided by clinicians for this issue. Further research is required to identify clearer treatment options and pathways.

Abstract
Objective Patients with COVID-19 are at risk for laryngeal injury and dysfunction secondary to respiratory failure, prolonged intubation, and other unique facets of this illness. Our goal is to report clinical features and treatment for patients presenting with voice, airway, and/or swallowing concerns postacute COVID-19. Study Design Case series. Setting Academic tertiary care center. Methods Patients presenting with laryngeal issues following recovery from COVID-19 were included after evaluation by our laryngology team. Data were collected via retrospective chart review from March 1, 2020, to April 1, 2021. This included details of the patient’s COVID-19 course, initial presentation to laryngology, and subsequent treatment. Results Twenty-four patients met inclusion criteria. Twenty (83%) patients were hospitalized, and 18 required endotracheal intubation for a median (range) duration of 14 days (6-31). Ten patients underwent tracheostomy. Patients were evaluated at a median 107 days (32-215) after their positive SARS-CoV-2 test result. The most common presenting concerns were dysphonia (n = 19, 79%), dyspnea (n = 17, 71%), and dysphagia (n = 6, 25%). Vocal fold motion impairment (50%), early glottic injury (39%), subglottic/tracheal stenosis (22%), and posterior glottic stenosis (17%) were identified in patients who required endotracheal intubation. Patients who did not need intubation were most frequently treated for muscle tension dysphonia (67%). Conclusion Patients may develop significant voice, airway, and/or swallowing issues postacute COVID-19. These complications are not limited to patients requiring intubation or tracheostomy. Multidisciplinary laryngology clinics will continue to play an integral role in diagnosing and treating patients with COVID-19–related laryngeal sequelae.

Abstract
BACKGROUND Tracheal and laryngotracheal surgery provides both excellent functional results and long-term outcomes in the treatment of tracheal stenosis. Consequently, challenging re-resections are rarely necessary. The purpose of this study was to compare the outcome of (laryngo-)tracheal re-resection and surgery after bronchoscopic interventions with that of primary surgery. METHODS Patients undergoing resection for benign tracheal stenosis at our center between 1/2016 and 4/2020 were included. Perioperative characteristics and functional outcomes of patients were used for statistical analysis. RESULTS Sixty-six patients who underwent (laryngo-)tracheal resection were included (previous resection [A = 6], previous stent [B = 6], previous bronchoscopic intervention w/o stenting [C = 19], untreated [D = 35]). Baseline parameters were largely comparable between groups with exception from group B that had significantly worse lung function. Group A necessitated more complex reconstructions (end-to-end: n = 1: 17%| cricotracheal n = 2: 33%| cricotracheal with mucosectomy n = 2: 33%| laryngoplasty: n = 1: 17%) than patients in group D (end-to-end n = 21: 60%| cricotracheal n = 14: 40%). Postoperative outcomes were comparable throughout groups (intensive care unit: 1[1-18] days; hospital stay: 8[5-71] days). Anastomotic complications were higher after previous stenting (A: 0%; B: 33.3%; C: 10.5%; D: 2.9%; B/D p = 0.008| surgical revisions: A: 16.7%; B: 33.3%; C: 0%; D: 5.7%; B/D, p = 0.035). Overall, postoperative lung function was significantly better (forced expiratory volume in 1 second: 63% ± 24 vs. 75% ± 20; p = 0.001 | PeakEF 3.3 ± 1.9 vs. 5.0 ± 2.2L; p = 0.001). No 90-day mortality was observed in any group. Median follow-up was 12(1-47) months. CONCLUSION In carefully selected patients treated in a specialized center, tracheal or laryngotracheal resection after previous tracheal interventions provides comparable outcome to primary surgery.

Not Just Dyspnoea: Swallowing as a Concern for Adults with Laryngotracheal Stenosis Undergoing Airway Reconstruction. Dysphagia 2021; 37:365-374. [PMID: 33830348 PMCID: PMC8948149 DOI: 10.1007/s00455-021-10287-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Accepted: 03/16/2021] [Indexed: 10/25/2022]
Abstract
Acquired laryngotracheal stenosis (LTS) is a rare condition causing dyspnea and stridor. Patients often require multiple surgical procedures with no guarantee of a definitive outcome. Difficulty swallowing is a recognised problem associated with LTS and the reconstructive surgeries required to manage the condition. The breathlessness patient's experience impacts on swallowing, and the vulnerable structures of the larynx are implicated during complex surgeries. This leads to dysphagia post-surgery, with some patients experiencing more chronic symptoms depending on the biomechanical impact of the surgery, or a pre-existing dysphagia. Despite this there is limited observational research about the dysphagia associated with LTS, with no exploration of the patient experience. Our aim was to investigate patient experience of living with LTS focussing on dysphagia in order to guide clinical practice. A qualitative study was completed using focus groups and semi-structured interviews with 24 patients who have had reconstructive surgery for LTS. Thematic analysis was used to identify three over-arching themes: The Physical Journey, The Emotional Journey and The Medical Journey. Key sub-themes included the importance of self-management and control, presence of symptoms, benefits of therapy, living with a life-long condition, fear and anxiety, autonomy, medicalisation of normal processes and the dichotomy between staff expertise and complacency. Swallowing was connected to all themes. The results are reviewed with consideration of the wider literature of lived experience particularly in relation to other chronic conditions and those that carry a high symptom burden such as head and neck cancer. Future clinical and research recommendations have been made. Akin to other clinical groups, adults with LTS are keen that management of their swallowing is person-centred and holistic.

Abstract
OBJECTIVES To investigate surgical adjuncts (stents) and previous surgeries on outcomes from posterior glottic stenosis (PGS). METHODS PubMED/Medline, CINAHL, EMBASE, and Web of Science were searched for publications on adult patients undergoing surgery for PGS. Decannulation and need for additional surgeries were evaluated as outcomes. Linear mixed-effects (with random effects and fixed effects) models were used for multivariate testing. RESULTS In total, 516 abstracts were reviewed and 26 articles were considered for systematic review. Of these, 19 articles with 140 pooled patient cases were extracted for meta-analysis. On multivariate meta-analysis analysis accounting for study-specific variation and use of open procedures, prior surgeries were associated with additional surgeries (RR = 3.76 [1.39-3.86], P = .038) and the use of a stent was associated with a lower likelihood of decannulation (RR = 0.42 [0.09-0.98], P = .044). CONCLUSION Minimizing repeat surgery is a predictor for avoiding additional future surgeries and use of a stent was correlated with poor outcomes. These 2 findings may assist providers in patient counseling regarding the need for further surgical interventions. Further, this study is the first to compare the efficacy of surgical approaches for the resolution of PGS, and highlights the importance of avoiding repeat procedures and stents for the management of PGS.

Abstract
Question What are the outcomes of the 3 most common surgical approaches for idiopathic subglottic stenosis (iSGS)? Findings In this cohort study of 810 patients with iSGS who underwent 1 of the 3 most common surgical treatments, 23% of patients underwent a recurrent surgical procedure during the 3-year study period, but recurrence differed by modality (cricotracheal resection, 1%; endoscopic resection with adjuvant medical therapy, 12%; and endoscopic dilation, 28%). Among successfully treated patients, those who underwent cricotracheal resection reported the highest quality of life but the greatest perioperative risk and worst long-term voice outcomes. Meaning These results show the feasibility of integrating an engaged rare disease community with a network of surgeons to facilitate rapid and nuanced treatment comparisons; findings may help inform treatment decision-making in iSGS. Importance Surgical treatment comparisons in rare diseases are difficult secondary to the geographic distribution of patients. Fortunately, emerging technologies offer promise to reduce these barriers for research. Objective To prospectively compare the outcomes of the 3 most common surgical approaches for idiopathic subglottic stenosis (iSGS), a rare airway disease. Design, Setting, and Participants In this international, prospective, 3-year multicenter cohort study, 810 patients with untreated, newly diagnosed, or previously treated iSGS were enrolled after undergoing a surgical procedure (endoscopic dilation [ED], endoscopic resection with adjuvant medical therapy [ERMT], or cricotracheal resection [CTR]). Patients were recruited from clinician practices in the North American Airway Collaborative and an online iSGS community on Facebook. Main Outcomes and Measures The primary end point was days from initial surgical procedure to recurrent surgical procedure. Secondary end points included quality of life using the Clinical COPD (chronic obstructive pulmonary disease) Questionnaire (CCQ), Voice Handicap Index-10 (VHI-10), Eating Assessment Test-10 (EAT-10), the 12-Item Short-Form Version 2 (SF-12v2), and postoperative complications. Results Of 810 patients in this cohort, 798 (98.5%) were female and 787 (97.2%) were white, with a median age of 50 years (interquartile range, 43-58 years). Index surgical procedures were ED (n = 603; 74.4%), ERMT (n = 121; 14.9%), and CTR (n = 86; 10.6%). Overall, 185 patients (22.8%) had a recurrent surgical procedure during the 3-year study, but recurrence differed by modality (CTR, 1 patient [1.2%]; ERMT, 15 [12.4%]; and ED, 169 [28.0%]). Weighted, propensity score–matched, Cox proportional hazards regression models showed ED was inferior to ERMT (hazard ratio [HR], 3.16; 95% CI, 1.8-5.5). Among successfully treated patients without recurrence, those treated with CTR had the best CCQ (0.75 points) and SF-12v2 (54 points) scores and worst VHI-10 score (13 points) 360 days after enrollment as well as the greatest perioperative risk. Conclusions and Relevance In this cohort study of 810 patients with iSGS, endoscopic dilation, the most popular surgical approach for iSGS, was associated with a higher recurrence rate compared with other procedures. Cricotracheal resection offered the most durable results but showed the greatest perioperative risk and the worst long-term voice outcomes. Endoscopic resection with medical therapy was associated with better disease control compared with ED and had minimal association with vocal function. These results may be used to inform individual patient treatment decision-making.

[PMID: 31943240 PMCID: PMC7754401 DOI: 10.1002/lary.28494] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 12/10/2019] [Accepted: 12/12/2019] [Indexed: 12/29/2022]
Abstract
OBJECTIVES Laryngotracheal stenosis is a rare condition characterized by upper airway narrowing. Reconstructive surgical treatment aims to manage the area of stenosis to improve dyspnea and can impact voice and swallowing function. This article critically evaluates the literature about voice and swallowing outcomes in adults with laryngotracheal stenosis who undergo reconstructive surgery. STUDY DESIGN Systematic review. METHODS Six databases were searched for articles referring to voice and swallowing outcome measures following reconstruction procedures in adults with laryngotracheal stenosis. Screening was completed using predefined inclusion/exclusion criteria. RESULTS A total of 143 abstracts were reviewed, with 67 articles selected for full-text review. Twenty studies met the inclusion criteria. Data extraction was completed with the Strengthening Reporting of Observational Studies in Epidemiology checklist with Oxford Centre for Evidence-Based Medicine Level of Evidence used to indicate quality. Risk of bias was assessed using the Risk of Bias Assessment Tool for Non-Randomized Studies. All studies scored a high risk of bias in at least one of the domains. Selection and timing of outcome measures was heterogenous, and there was limited information provided about rationale or reliability. CONCLUSIONS The literature acknowledges the importance of voice and swallowing outcomes following airway reconstruction. Studies show correlation between reconstructive surgery and deterioration in vocal function; there are no consistent data about swallowing outcomes. The lack of a core outcome measures set for adults with laryngotracheal stenosis limits the findings of this review. Further research is needed to establish clear criteria for robust and clinically relevant outcome measurement. Laryngoscope, 131:146-157, 2021.

Abstract
OBJECTIVES This article reports on a unique cohort of patients with idiopathic subglottic stenosis spilt fairly equally between endoscopic and open surgical approaches. Patients' sequence of operations and reinterventions over time are outlined, offering insight to improve surgical counseling and allow for informative, autonomous patient decision making. STUDY DESIGN Retrospective cohort study. SETTING Tertiary care academic center. METHODS Cases of consecutive adults with idiopathic subglottic stenosis managed surgically over a 12-year period (January 2006-December 2017) were retrospectively reviewed. Surgical workflow, complications, and outcomes, including reinterventions and tracheotomy dependence, are reported. RESULTS Seventy-two patients (71 women; mean age, 50.4 years) with idiopathic subglottic stenosis requiring surgical airway intervention were identified. Six patients underwent tracheotomy prior to attempt at airway stenosis surgery. Initial surgical approach thereafter included endoscopic (73.5%, n = 53) and open (26.4%, n = 19) procedures. Thirty-one patients underwent cricotracheal resection; the reintervention rate was 22.5%. Sixty patients underwent 147 endoscopic procedures; the reintervention rate was 75.5%, and the mean time between dilations was 83 weeks (range, 5-402). Two (2.8%) patients remain tracheotomy dependent. Adverse events were significantly higher in the cricotracheal group, especially with respect to dysphonia and temporary gastrostomy tube placement (P < .01). CONCLUSIONS Endoscopic and open surgical airway intervention can be employed successfully to avoid tracheotomy dependence and maintain airway patency; however, multiple procedures are usually required, regardless of surgical approach. Cricotracheal reintervention rates are lower than endoscopic dilation but with increased morbidity. Quality-of-life outcomes should be clearly discussed with patients before deciding on a surgical management strategy.

Transoral management of adult benign laryngeal stenosis. Eur Arch Otorhinolaryngol 2020; 278:149-158.

Abstract
PURPOSE Management of benign laryngeal stenosis (BLS) remains challenging even though transoral treatments in selected cases have shown satisfactory results, at least comparable to open-neck approaches, with reduced invasiveness. To date, no overall consensus has been reached on many issues. The aim of this study is to assess the effectiveness of a purely transoral treatment in a cohort of patients affected by BLS. METHODS We evaluated 40 patients affected by BLS, treated by transoral surgery between 2013 and 2017. The European Laryngological Society classification for laryngotracheal stenosis was applied for the staging. Improvement in airway patency and quality of life was assessed by decannulation rate, Airway-Dyspnea-Voice-Swallowing (ADVS) score, Voice handicap index (VHI)-30, and Eating assessment tool (EAT)-10 questionnaires. RESULTS Mean age was 61 years and M:F ratio was 1.4:1. Previous laryngeal surgery was the most common cause of stenosis (50%), followed by radiotherapy (20%), idiopathic etiology (12%), granulomatosis with polyangiitis (10%), and prolonged intubation (8%). Transoral treatment entailed an improvement in quality of life with a significant decrease in the VHI score (p < 0.0001) and improvement in Airway (p = 0.008), Dyspnea (p < 0.0001), and Voice (p < 0.0001) scores. No major perioperative complications were observed. The decannulation rate among patients with a tracheostomy in place (N = 16) was 63%. CONCLUSIONS Transoral treatment of selected BLS managed by a team with high-level expertise in surgery and anesthesiology is associated with significant improvement of quality of life, especially with regard to voice and breathing functions.

Abstract
OBJECTIVE Idiopathic subglottic stenosis (iSGS) is a chronic inflammatory condition that causes dyspnea and affects middle-aged women of White race and non-Latino or Hispanic ethnicity. To better characterize its phenotype and pathogenesis, we assessed the proteomic and genomic methylation signatures of subglottic tissue collected from iSGS patients compared to controls. STUDY DESIGN Molecular analysis of clinical biospecimens. METHODS We collected subglottic tissue biopsies from 12 patients during direct laryngoscopy, immediately prior to surgical treatment of iSGS; as well as from 4 age-, sex-, and race/ethnicity-matched control patients undergoing other direct laryngoscopic procedures. We isolated protein and genomic DNA, acquired proteomic data using label-free quantitative mass spectrometry techniques, and acquired genome-wide methylation data using bisulfite conversion and a microarray platform. We compared molecular profiles across the iSGS and control groups, and with respect to clinical course in the iSGS group. Eight of the 12 iSGS patients underwent subsequent blood collection and plasma isolation for further assessment. RESULTS Proteomic analysis revealed 42 differentially abundant proteins in the iSGS biopsies compared to controls, inferring enrichment of biological pathways associated with early wound healing, innate immunity, matrix remodeling, and metabolism. Proteome-based hierarchical clustering organized patients into two iSGS and one control subgroups. Methylation analysis revealed five hypermethylated genes in the iSGS biopsies compared to controls, including the biotin recycling enzyme biotinidase (BTD). Follow-up analysis showed elevated plasma BTD activity in iSGS patients compared to both controls and published normative data. CONCLUSION iSGS exhibits distinct proteomic and genomic methylation signatures. These signatures expand current understanding of the iSGS phenotype, support the possibility of disease subgroups, and should inform the direction of future experimental studies.

Abstract
OBJECTIVES/HYPOTHESIS Identify predictors of decannulation failure after cricotracheal resection (CTR) and thyrotracheal anastomosis (TTA) in patients with subglottic stenosis (SGS). STUDY DESIGN Retrospective cohort study. METHODS Charts of patients undergoing CTR and TTA for SGS at the University Health Network, Toronto, Ontario, Canada between 1988 and 2017 were reviewed. Patient, pathology, treatment, and outcome data were collected. The end points for statistical analysis were development of restenosis and permanent tracheostomy. RESULTS One hundred fourteen patients (n = 114) were eligible for inclusion in this review. The mean age at primary resection was 46.9 years, 95 (83%) were females, and 19 (17%) were males. The rate of restenosis and permanent tracheostomy was 13% and 5%, respectively. Sixty-two patients (54%) underwent a CTR and TTA, and 52 patients (46%) underwent a CTR, laryngofissure, and TTA. Traumatic stenosis (odds ratio [OR] = 10.3, P = .017), longer T-tube duration (OR = 1.2, P = .011), combined glottic/subglottic stenosis (OR = 10.47, P = .010), start of the stenosis at the vocal cords (OR = 6.6, P = .029), postoperative minor complications (OR = 13.6, P = .028), and need for repeat surgery (OR = 44.1, P < .001) were associated with an increased risk of requiring permanent tracheostomy. CONCLUSIONS CTR and TTA are excellent surgical approaches for adult patients with subglottic stenosis. In this study, 5% of patients required permanent tracheostomy. Factors predicting treatment failure include traumatic stenosis, longer T-tube duration, combined glottic/subglottic stenosis, start of stenosis at the level of vocal cords, postoperative minor complications, and need for repeat surgery.

Vocal fold fixation due to proximal stenosis progression complicating idiopathic subglottic stenosis. Eur Arch Otorhinolaryngol 2019; 276:2293-2300. [PMID: 31187240 PMCID: PMC6616212 DOI: 10.1007/s00405-019-05494-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2019] [Accepted: 04/09/2019] [Indexed: 11/03/2022]
Abstract
Purpose This study examined the incidence and risk factors for vocal fold fixation due to proximal progression of idiopathic subglottic stenosis (ISS) over the course of serial treatments. Methods Records of 22 consecutive patients with ISS treated between 2004 and 2016 were retrospectively reviewed. Patient, stenosis, and treatment details were recorded. Cox regression was used to identify independent predictors of vocal fold fixation. Results All patients were female and mean age at diagnosis was 46 ± 7 years. In five patients, the stenosis was within 15 mm of the glottis at first treatment. Vocal fold fixation due to proximal stenosis progression occurred in seven (32%) patients. It led to permanent hoarseness due to unilateral vocal fold fixation in two patients and caused airway compromise due to bilateral vocal fixation in two other patients. No airway-related deaths occurred and no patient required a tracheostomy. Stenosis incision using coblation or potassium titanyl phosphate laser, and an initial glottis-to-stenosis (GtS) distance < 15 mm significantly increased the risk of proximal stenosis progression on univariable analysis. Conclusion Vocal fold fixation due to proximal stenosis progression is a significant complication of idiopathic subglottic stenosis and causes permanent voice and/or airway sequelae. It should be actively looked for and documented every time a patient is assessed. If a reduction in the GtS distance is observed, definitive surgery should be promptly considered before proximal stenosis progression compromises the efficacy and safety of definitive treatment or, worse, causes vocal fold fixation.
