RESUMEN
BACKGROUND: Laryngopharyngeal reflux (LPR) is a common otolaryngologic diagnosis. Treatment of presumed LPR remains challenging, and limited frameworks exist to guide treatment. METHODS: Using RAND/University of California, Los Angeles (UCLA) Appropriateness Methods, a modified Delphi approach identified consensus statements to guide LPR treatment. Experts independently and blindly scored proposed statements on importance, scientific acceptability, usability, and feasibility in a four-round iterative process. Accepted measures reached scores with ≥ 80% agreement in the 7-9 range (on a 9-point Likert scale) across all four categories. RESULTS: Fifteen experts rated 36 proposed initial statements. In round one, 10 (27.8%) statements were rated as valid. In round two, 8 statements were modified based on panel suggestions, and experts subsequently rated 5 of these statements as valid. Round three's discussion refined statements not yet accepted, and in round four, additional voting identified 2 additional statements as valid. In total, 17 (47.2%) best practice statements reached consensus, touching on topics as varied as role of empiric treatment, medication use, lifestyle modifications, and indications for laryngoscopy. CONCLUSION: Using a well-tested methodology, best practice statements in the treatment of LPR were identified. The statements serve to guide physicians on LPR treatment considerations.

BACKGROUND: Tracheotomy is a common procedure for otolaryngologists. The risk of complications is difficult to predict. This study aims to identify measurable preoperative indicators associated with adverse events following tracheotomy. METHODS: The charts of adults undergoing tracheotomy for respiratory failure at one of four university-affiliated hospitals between 1/2012 and 8/2018 were reviewed. Complications were analyzed in the context of demographics, physiologic parameters, and comorbidities. RESULTS: Among 507 tracheotomies performed, the most common complications included infection, bleeding, and cardiac arrest. Mortality was 39 % in patients with pulmonary hypertension, 42 % in those with ejection fraction ≤ 40 and 32 % in those with abnormal right ventricular function, double the rates in patients without each of these findings. CONCLUSION: Many critically ill tracheotomy patients experience significant rates of adverse events. Risk factors for mortality include ejection fraction ≤ 40, pulmonary hypertension, and abnormal ventricular function. These should be considered for use in preoperative counseling.

OBJECTIVE: To study the management of laryngopharyngeal reflux (LPR) among the subspecialties of practicing otolaryngology-head and neck surgeons and their trainees. METHODS: A survey was sent to over 8000 otolaryngologists (OTOHNS) over 65 countries, utilizing membership lists of participating otolaryngological societies. The outcomes were answers to questions regarding LPR knowledge and practice patterns, and included queries about its definition, prevalence, clinical presentation, diagnosis, and treatment. RESULTS: Of the 824 respondents, 658 practiced in one specific otolaryngologic subspecialty. The symptoms and findings thought to be the most related to LPR varied significantly between subspecialists. Extra-laryngeal findings were considered less by laryngologists while more experienced OTOHNS did not often consider digestive complaints. Compared with colleagues, otologists, rhinologists and laryngologists were less aware of the involvement of LPR in otological, rhinological and laryngological disorders, respectively. Irrespective of subspecialty, OTOHNS consider symptoms and signs and a positive response to empirical therapeutic trial to establish a LPR diagnosis. Awareness regarding the usefulness of impedance pH-studies is low in all groups. The therapeutic approach significantly varies between groups, although all were in agreement for the treatment duration. The management of non-responder patients demonstrated significant differences among laryngologists who performed additional examinations. The majority of participants (37.1%) admitted to being less than knowledgeable about LPR management. CONCLUSIONS: LPR knowledge and management vary significantly across otolaryngology subspecialties. International guidelines on LPR management appear necessary to improve knowledge and management of LPR across all subspecialties of otolaryngology.

BACKGROUND: Diagnosis and treatment of presumed laryngopharyngeal reflux (LPR) remain controversial. Empiric medication trials remain widespread for suspected LPR despite emerging evidence against proton pump inhibitor (PPI) safety and for pepsin as a mediator of LPR symptoms. Ongoing concerns exist related to inaccurate diagnosis, the cost and morbidity of potentially unnecessary PPI prescriptions, and availability and interpretation of objective reflux testing. OBJECTIVES: To review contemporary evidence that does and does not support empiric medication trials for presumed LPR. METHODS: PubMed, Scopus and Cochrane Library were searched for literature about benefits, limitations and alternatives to empiric medication trial for LPR, in order to present both sides of this debate and identify best practices. RESULTS: The majority of physicians perform prolonged empiric medication trial with PPIs for patients with suspected LPR. Because symptoms and signs of LPR are non-specific, empiric medication trials require exclusion of other conditions that can mimic LPR. Following a PPI empiric medication trial, over one-third of patients remain non-responders. The use of hypopharyngeal-oesophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH) has benefits and limitations in objective diagnosis of LPR. CONCLUSIONS: Use of PPIs for single-agent empiric medication trial does not account for possible non-responders with non-acid or mixed LPR. If LPR diagnosis remains uncertain, alginates can be added to PPI trials. HEMII-pH testing upfront is ideal for patients with suspected LPR, but not always practical; it is indicated when PPI and alginate empiric medication trials have failed or when comorbidities confuse the diagnosis. A more comprehensive, combination therapy empiric medication trial regimen may be needed.

Killian-Jamieson diverticulum is a outpouching of the lateral cervical esophageal wall adjacent to the insertion of the recurrent laryngeal to the larynx and is much less common in clinical practice than Zenkers Diverticulum. Surgical management of Killian-Jamieson diverticulum requires open transcervical diverticulectomy due to the proximity of the recurrent laryngeal nerve to the base of the pouch. We present a case of a Killian-Jamieson diverticulum associated with a concurrent large type III paraesophageal hernia causing significant solid-food dysphagia, post-prandial regurgitation of solid foods, and chronic cough managed with open transcervical diverticulectomy and laparoscopic paraesophageal hernia repair with Nissen fundoplication.

OBJECTIVES: We report a case of isolated pharyngeal plexus injury following posterior plating of a C2 fracture in an 84-year-old white male. METHODS: Methods include a case report with literature review. RESULTS: The patient presented with dense pharyngeal paralysis and inability to initiate swallowing but maintained true vocal cord movement. The patient required gastrostomy tube feeding for 3 months but eventually recovered his swallowing function. Prior literature on acute pharyngeal paralysis following upper cervical spine fracture repairs is reviewed with recommendations for care of this unique patient population. CONCLUSIONS: Traumatic C2 fracture repair can lead to isolated dense pharyngeal paralysis due to pharyngeal plexus injury with subsequent severe dysphagia. Observation may be appropriate in this population, with consideration of tracheotomy for recurrent aspiration.

OBJECTIVES: To compare patterns of laryngopharyngeal reflux (LPR) diagnosis and management over time by American Broncho-Esophagological Association (ABEA) members. METHODS: American Broncho-Esophagological Association members completed an online questionnaire focused on LPR evaluation and management in 2012; responses were compared to a 2002 survey. RESULTS: Four hundred twenty-six members were emailed, of whom 63 (14.8%) responded. In both time periods, throat clearing, heartburn, globus, arytenoid edema, and erythema were considered highly related to LPR. Management in 2012 differed as respondents more commonly treated LPR empirically (82.6% vs 56.3%, P = .036). When adjunctive testing was ordered, dual pH probe were less frequently utilized in 2012 (61.5% vs 78.3%, P = .029). Either esophagogastroduodenoscopy (EGD) or transnasal esophagoscopy (TNE) was used more often in 2012 compared to EGD alone in 2002 (63.8% vs 42.4%, P = .020). Dual pH probe was regarded as the most sensitive and specific evaluation for LPR in both surveys, while the perceived sensitivity/specificity of EGD in 2012 was half that reported in 2002 (28.0% vs 56.3%, P = .003). CONCLUSION: Attitudes of ABEA members toward empiric treatment and adjunctive tests have changed between 2012 and 2002. While pH probe testing remains the test regarded as most sensitive/specific for evaluation of LPR, empiric management has become more common. Meanwhile, EGD use has increased despite a significant decrease in its perceived sensitivity/specificity.

OBJECTIVE: This study aimed to describe current patterns for diagnosis and treatment of laryngopharyngeal reflux (LPR) and analyze differences between laryngologists and non-laryngologists. METHODS: American Academy of Otolaryngology-Head and Neck Surgery and American Broncho-Esophagological Association members were invited to complete an online survey regarding evaluation, diagnosis, and treatment of LPR. Subgroup analysis was performed to identify differences between respondents who completed laryngology fellowships (LF) and those who did not (NL). RESULTS: Of 159 respondents, 40 were LF. Video documentation of laryngopharyngeal exams was almost universal among LF (97% vs 38%, P < .0001). Use of rigid (100%, P = .002) and flexible distal-chip technologies (94%, P = .004) was more common among LF. Diagnostic criteria were similar between the groups, with symptoms of heartburn, globus, and throat clearing thought most suggestive of LPR. Adjunctive tests most commonly used were barium esophagram and dual-probe pH testing with impedance. Laryngology fellowship-trained respondents used dual pH probes with impedance more often (P = .004). They were more likely to prescribe twice daily proton pump inhibitors with concurrent H2-blocker medication initially (P = .004) and to treat for longer than 4 weeks (P = .0003). CONCLUSION: Otolaryngologists are in agreement on symptoms and physical features of LPR; however, significant differences exist between laryngologists and non-laryngologists on the use of adjunctive testing and treatment strategies.

OBJECTIVES: We report development of a device and technique to manage laryngeal paralysis through minimal-access arytenoid adduction (for unilateral paralysis) and arytenoid abduction (for bilateral paralysis). METHODS: A human cadaver study coupled with directed engineering was used to develop instrumentation designed to secure the muscular process of the arytenoid into favorable adducted or abducted positions. Digital video, photography, and 3-dimensional computed tomographic (CT) imaging of cadaveric larynges were done to evaluate the surgical technique. RESULTS: Testing of prototypes identified the ideal implant to be a 0.36-mm wire with a distal spring-wound coil placed through a trocar via a small drill hole in the anterior thyroid cartilage. An endoscopic view of transilluminated light through the pyriform sinus mucosa identified the tip location of the trocar adjacent to the muscular process of the arytenoid cartilage. Placement of the device through the trocar permitted rotation to engage the muscular process and/or adjacent soft tissue with the distal coil. Implant fixation to the thyroid cartilage positioned the vocal cord into either adduction or abduction. Three-dimensional CT imaging coupled with review of the video documentation established the feasibility of this technique. CONCLUSIONS: We confirm the feasibility of minimal-access arytenoid adduction and abduction through development of a new technique and device.

OBJECTIVE: To evaluate the efficacy of distal esophageal mean nocturnal baseline impedance (MNBI), a general marker of esophageal mucosal barrier integrity, in predicting laryngopharyngeal reflux (LPR) and symptomatic response to acid reflux therapy. METHODS: This retrospective study analyzed 173 patients who presented with symptoms of laryngopharyngeal reflux and underwent 24-h multichannel intraluminal impedance-pH (MII-pH) testing. Mean nocturnal baseline impedance values were calculated and assessed for their association and ability to predict LPR symptoms, MII-pH results, treatment response, and other markers of LPR. RESULTS: Notably, 153 of the 173 patients were tested off acid suppression medication and included in statistical analysis. Based on the MII-pH probe data, 108 (71%) patients had LPR, 8 (5%) had gastroesophageal reflux disease (GERD), and 37 (24%) were without pathologic reflux. Distal esophageal MNBI of LPR patients was significantly lower in LPR patients than patients with negative studies (1332 ± 94.8 vs. 2158 ± 173.5, p = 0.001). Among 118 patients who trialed antireflux therapy, a distal esophageal MNBI cutoff value of <1580 Ω was an independent predictor of treatment response (OR = 4.148 [1.877-9.189]). This value better predicted improvement with antireflux therapy for LPR than other objective MII-pH probe data, which were not independent predictors of treatment response. CONCLUSION: Distal esophageal MNBI values may have value in the diagnosis of LPR and potentially predict medication responsiveness in LPR patients.

OBJECTIVES: Limited research exists evaluating the impact of social determinants of health in influencing care pathways for patients with dysphagia. A better understanding of whether these determinants correlate to altered care and resource utilization is essential as it relates to patient outcomes. STUDY DESIGN: Retrospective chart review. METHODS: All adult patients seen at a tertiary midwestern hospital were screened for ICD codes of dysphagia diagnoses from 2009 to 2019. Demographic information was collected from these patients with dysphagia including sex, race, ethnicity, and insurance status. Subgroup analysis was performed to assess referral pattern rates and types of diagnostic interventions ordered (none, videofluoroscopic swallow study, esophagram, and esophagogastroduodenoscopy). RESULTS: A total of 31,858 patients with dysphagia were seen at our institution during the study period, with a majority being female (56.36%), Caucasian (79.83%), and publicly insured (63.16%), at a median age of 60.35 years. There were no significant care delivery pattern differences based on geography/zip code analyses. African American patients were significantly more likely to have imaging or interventions performed (odds ratio [OR] 1.463, p = 0.005). Patients with public insurance also had higher rates of diagnostic study utilization (OR 1.53, p = 0.01). Only 3% of all patients with dysphagia were seen by laryngologists. CONCLUSION: No significant differences were seen in dysphagia evaluation modalities based on zip code analyses surrounding this tertiary care facility. African American patients and those with public insurance had significantly higher utilization of subsequent testing and intervention for dysphagia care. Further studies are necessary to delineate causes and outcome differences for these measurable differences in dysphagia care pathways. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:1139-1146, 2024.

Objectives: Approximately 25% of Americans suffer from laryngopharyngeal reflux (LPR), a disease for which no effective medical therapy exists. Pepsin is a predominant source of damage during LPR and a key therapeutic target. Fosamprenavir (FOS) inhibits pepsin and prevents damage in an LPR mouse model. Inhaled FOS protects at a lower dose than oral; however, the safety of inhaled FOS is unknown and there are no inhalers for laryngopharyngeal delivery. A pre-Good Lab Practice (GLP) study of inhaled FOS was performed to assess safety and computational fluid dynamics (CFD) modeling used to predict the optimal particle size for a laryngopharyngeal dry powder inhaler (DPI). Methods: Aerosolized FOS, amprenavir (APR), or air (control) were provided 5 days/week for 4 weeks (n = 6) in an LPR mouse model. Organs (nasal cavity, larynx, esophagus, trachea, lung, liver, heart, and kidney) were assessed by a pathologist and bronchoalveolar lavage cytokines and plasma cardiotoxicity markers were assessed by Luminex assay. CFD simulations were conducted in a model of a healthy 49-year-old female. Results: No significant increase was observed in histologic lesions, cytokines, or cardiotoxicity markers in FOS or APR groups relative to the control. CFD predicted that laryngopharyngeal deposition was maximized with aerodynamic diameters of 8.1-11.5 µm for inhalation rates of 30-60 L/min. Conclusions: A 4-week pre-GLP study supports the safety of inhaled FOS. A formal GLP assessment is underway to support a phase I clinical trial of an FOS DPI for LPR. Level of Evidence: NA.
RESUMEN
OBJECTIVE: To provide detailed guidance on the administration of systemic bevacizumab in patients with recurrent respiratory papillomatosis (RRP) based on a detailed review of the scientific literature and a consensus of experts with real-world clinical experience. METHODS: A bevacizumab consensus working group (N = 10) was composed of adult and pediatric otolaryngologists, adult and pediatric oncologists, and a representative from the RRP Foundation (RRPF), all with experience administering systemic bevacizumab in patients with RRP. After extensive review of the medical literature, a modified Delphi method-based survey series was utilized to establish consensus on the following key areas: clinical and patient characteristics ideal for treatment candidacy, patient perspective in treatment decisions, treatment access, initial dosing, monitoring, guidelines for tapering and discontinuation, and reintensifying therapy. RESULTS: Seventy-nine statements were identified across nine critical domains, and 45 reached consensus [clinical benefits of bevacizumab (3), patient and disease characteristics for treatment consideration (7), contraindications for treatment (3), shared decision-making (incorporating the patient perspective) (5), treatment access (3), initial dosing and administration (8), monitoring (7), tapering and discontinuation (6), and reintensification (3)]. CONCLUSION: This consensus statement provides the necessary guidance for clinicians to initiate systemic administration of bevacizumab and represents a potential paradigm shift toward nonsurgical treatment options for patients with RRP. LEVEL OF EVIDENCE: 5 Laryngoscope, 2024.
RESUMEN
OBJECTIVE: The objective of this work was to gather an international consensus group to propose a global definition and diagnostic approach of laryngopharyngeal reflux (LPR) to guide primary care and specialist physicians in the management of LPR. METHODS: Forty-eight international experts (otolaryngologists, gastroenterologists, surgeons, and physiologists) were included in a modified Delphi process to revise 48 statements about definition, clinical presentation, and diagnostic approaches to LPR. Three voting rounds determined a consensus statement to be acceptable when 80% of experts agreed with a rating of at least 8/10. Votes were anonymous and the analyses of voting rounds were performed by an independent statistician. RESULTS: After the third round, 79.2% of statements (N = 38/48) were approved. LPR was defined as a disease of the upper aerodigestive tract resulting from the direct and/or indirect effects of gastroduodenal content reflux, inducing morphological and/or neurological changes in the upper aerodigestive tract. LPR is associated with recognized non-specific laryngeal and extra-laryngeal symptoms and signs that can be evaluated with validated patient-reported outcome questionnaires and clinical instruments. The hypopharyngeal-esophageal multichannel intraluminal impedance-pH testing can suggest the diagnosis of LPR when there is >1 acid, weakly acid or nonacid hypopharyngeal reflux event in 24 h. CONCLUSION: A global consensus definition for LPR is presented to improve detection and diagnosis of the disease for otolaryngologists, pulmonologists, gastroenterologists, surgeons, and primary care practitioners. The approved statements are offered to improve collaborative research by adopting common and validated diagnostic approaches to LPR. LEVEL OF EVIDENCE: 5 Laryngoscope, 134:1614-1624, 2024.

OBJECTIVES: We present the second published case of laryngeal involvement in mitochondrial myopathy. METHODS: A patient with laryngeal involvement of mitochondrial myopathy is presented, together with a literature review. RESULTS: A 41-year-old man presented with progressive breathy dysphonia. His brother had mitochondrial myopathy. Biopsy of the biceps muscle demonstrated cytochrome C oxidase-negative ragged blue fibers confirming mitochondrial myopathy. Videostroboscopy showed marked vocal fold atrophy, but subsequent injection laryngoplasty did not significantly improve the patient's voice, despite improved postoperative glottic closure. CONCLUSIONS: Mitochondrial myopathy should be considered in the differential diagnosis of severe early-onset vocal fold atrophy.

OBJECTIVES: We sought to review the dysphagia-related outcomes and quality of life in a series of patients with upper esophageal sphincter (UES) dysfunction treated with cricopharyngeal (CP) botulinum toxin (BTX) injection, and to identify patient characteristics or CP muscle histologic features that predict efficacy of BTX injection. METHODS: A retrospective chart review was performed on patients with UES dysfunction who underwent CP BTX injection. Dysphagia-related quality-of-life questionnaires based on the Eating Assessment Tool (EAT-10) were mailed to patients. RESULTS: Forty-nine patients (30 female, 19 male; average age, 59 +/- 16 years) with UES dysfunction have been treated at our institution with CP BTX injection since 2000. Seventeen of these patients also underwent CP myotomy. Injections of BTX were occasionally repeated after the treatment effect subsided, and the BTX dose varied widely (average, 39 +/- 19 units). Improvement in symptoms was noted by 65% of patients. The overall complication rate was minimal, although many patients complained of transient worsening of dysphagia after CP BTX injection. Biopsy specimens of the CP muscle were evaluated in the subset of patients with CP BTX injection who proceeded to myotomy, with results of neuropathic, myopathic, and mixed histologic subtypes. The EAT-10 scores demonstrated a general trend toward improved swallowing outcomes after CP BTX injection. CONCLUSIONS: This study reviewed findings from the largest published series of BTX treatment of UES dysfunction and evaluated the efficacy, patient satisfaction, and complications of this procedure. Dysphagia-related quality-of-life outcomes appear to be improved after CP BTX injection.

OBJECTIVES: Mean nocturnal baseline impedance (MNBI) is a measure of the esophageal epithelial barrier function calculated via high-resolution impedance manometry and can be used as a diagnostic tool and treatment response predictor for gastroesophageal reflux disease (GERD). However, its utility for laryngopharyngeal reflux (LPR) has been minimally studied. We aimed to investigate the relationship of MNBI between patients with suspected LPR, healthy controls, and their 24-h multichannel intraluminal impedance-pH (MII-pH) study results. METHODS: Retrospective patient series analysis was performed of patients with suspected LPR and healthy controls who underwent 24-h MII-pH monitoring. MNBI values were calculated from impedance channels at the level of the hypopharynx, proximal esophagus, and distal esophagus. We compared these MNBI values between the subject groups with secondary analysis on MII-pH results, reflux symptom index, reflux findings score, DeMeester score, and salivary pepsin levels. RESULTS: Twenty-three patients with suspected LPR and 14 healthy controls were enrolled. Decreased distal esophageal MNBI was found to be significantly decreased in patients with suspected LPR compared with healthy controls (p < 0.01) and in subjects with positive MII-pH studies compared to negative MII-pH studies (p < 0.01). There were no significant correlations of MNBI at the hypopharynx or proximal esophagus. CONCLUSION: Distal esophageal MNBI has significant correlations with many phenotypic and biological markers of LPR. These findings indicate that MNBI has the potential to be applied to LPR, similar to its emerging use as a diagnostic tool and treatment response predictor for GERD.

The North American Airway Collaborative (NoAAC) previously published a 3-year multi-institutional prospective cohort study showing variation in treatment effectiveness between 3 primary surgical techniques for idiopathic subglottic stenosis (iSGS). In this report, we update these findings to include 5 years of data evaluating treatment effectiveness. Patients in the NoAAC cohort were re-enrolled for 2 additional years and followed using the prespecified published protocol. Consistent with prior data, prospective observation of 487 iSGS patients for 5 years showed treatment effectiveness differed by modality. Cricotracheal resection maintained the lowest rate of recurrent operation (5%), followed by endoscopic resection with adjuvant medical therapy (30%) and endoscopic dilation (50%). These data support the initial observations and continue to provide value to providers and patients navigating longitudinal decision-making. Level of evidence: 2-prospective cohort study.

OBJECTIVES: Although oropharyngeal neoplasia can often lead to dysphagia, salivary gland tumors rarely grow within the tongue base. We present the case of a 75-year-old man with adenoid cystic carcinoma of the base of the tongue causing profound dysphagia and weight loss, and provide a current literature review and update on the management of these rare tumors. METHODS: We present a case report and a literature review. RESULTS: Physical examination performed at the initial visit revealed a firm right base-of-tongue mass with no palpable lymphadenopathy. Flexible fiberoptic laryngoscopy confirmed a large submucosal mass at the right base of the tongue that obscured the right vallecula. Histopathologic analysis of the operative biopsy specimens revealed the classic features of adenoid cystic carcinoma. Treatment included radical pharyngotomy with wide local excision and primary closure, followed by postoperative radiation treatment. CONCLUSIONS: We demonstrate the clinical examination findings and histopathologic characteristics of this disease, and review the literature for clinical treatment recommendations for this rare cause of dysphagia.

Objective: To determine the impact of patient demographics and social determinants of health on treatment pathways for unilateral vocal fold paralysis (UVFP) at a tertiary laryngology clinic. Study design: Retrospective medical record review. Methods: Patient demographics (age, gender, race, ethnicity, and insurance status) were extracted for adults diagnosed with UVFP between 2009 and 2019. Odds ratios for the associations between sociodemographic factors and UVFP treatment pathways were determined by chi-square analyses. Results: A total of 1490 UVFP diagnoses were identified during the study period with the majority being female (58%), White (85%), non-Hispanic (97%), and publicly insured (54%). Five treatment pathways were identified: observation, injection laryngoplasty, voice therapy, laryngeal framework surgery/thyroplasty, and reinnervation surgery. There were 538 patients who underwent observation, 512 injection laryngoplasty, 366 voice therapy, 136 thyroplasty, and 26 laryngeal reinnervation surgery. Males were more likely to undergo injection laryngoplasty than females (OR 1.32; CI 1.08-1.61), whereas females were more likely to undergo voice therapy (OR 1.39; CI 1.09-1.76). Patients with public insurance (OR 1.48; CI 1.03-2.14) and Hispanics (OR 2.60; CI 1.18-5.72) were more likely to undergo thyroplasty. Patients who underwent reinnervation surgery were younger than those in other treatment pathways (median: 39.1 years vs. 50.7-56.1 years). Conclusions: Gender, ethnicity, and insurance status were significantly associated with specific UVFP treatment pathways. Patients with public insurance were more likely to undergo surgical intervention than voice therapy. This data overall supports differences in care pathway utilization for UVFP based on social determinants of health. Level of evidence: Level IV.
