Abstract
PURPOSE OF REVIEW Symptoms/complications related to extraesophageal reflux (EER) are increasingly prevalent presentations and pose significant challenges for clinicians. We summarize and discuss clinical advances and developments in pathophysiology, testing and treatment algorithms of upper/lower airway manifestations of EER. RECENT FINDINGS Growing evidence supports likely multifactorial causes of laryngeal symptoms, including EER, oropharyngeal pathologies, allergic conditions, and cognitive-affective processes (brain-larynx interaction). Diagnostic paradigm for laryngopharyngeal reflux (LPR) is shifting towards a personalized approach with noninvasive strategies/prediction tools to risk-stratify patients for upfront reflux testing over empiric acid suppression trials. Management should be multipronged to include antireflux therapies and treatments targeting other causes. Lower airway complications of EER may result in lung dysfunction and poor transplant outcomes. Esophageal symptoms are often absent and routine esophageal/reflux testing to guide timely antireflux therapies may lead to improved outcomes. Modalities that leverage impedance technology may be important, given the potential role of nonacidic reflux. Novel impedance-based metrics such as mean nocturnal baseline impedance and postreflux swallow-induced peristaltic wave index may provide adjunctive diagnostic values. SUMMARY Standardized approach to diagnosis/management of EER should include multidisciplinary care teams and consider different phenotypes, nonreflux contributors, and the complex gut-airway relationships. Prompt antireflux therapies after careful candidate selection may improve outcomes of these airway complications.

Abstract
INTRODUCTION Magnetic sphincter augmentation (MSA) is an effective treatment for typical reflux symptoms, but data on its impact on laryngopharyngeal reflux (LPR) is limited. This study aimed to determine the efficacy of MSA for LPR and to identify predictors of outcome. METHODS This was a retrospective review of 775 patients who underwent MSA between 2013 and 2021. LPR was defined as presence of atypical reflux symptoms and a reflux symptom index (RSI) score >13. Favorable outcome was defined as primary symptom resolution, freedom from proton pump inhibitors, and five-point improvement or RSI score normalization. Preoperative clinical, high-resolution manometry, and impedance-pH data were analyzed for impact on favorable outcome using univariate followed by multivariable analysis. RESULTS There were 128 patients who underwent MSA for LPR. At a mean (SD) follow-up of 13 (5.4) months, favorable outcome was achieved by 80.4% of patients, with median (IQR) RSI score improving from 29 (22-35) to 9 (4-17), (P < 0.001). Independent predictors of favorable outcome on multivariable analysis included LPR with typical reflux symptoms [OR (95% CI): 8.9 (2.3-31.1), P = 0.001], >80% intact swallow on high-resolution manometry [OR (95% CI): 3.8 (1.0-13.3), P = 0.035], upper esophageal sphincter (UES) resting pressure >34 mmHg [OR (95% CI): 4.1 (1.1-14.1), P = 0.027] and short total proximal acid clearance time [OR (95% CI): 1.1 (1.0-1.1), P = 0.031]. Impedance parameters including number of LPR events, full column reflux and proximal acid exposure events were similar between outcome groups (P > 0.05). CONCLUSION MSA is an effective surgery for patients with LPR. Patients with concomitant typical reflux symptoms, normal esophageal body motility, and competent UES benefit the most from surgery. Individual impedance-pH parameters were not associated with outcome.

Abstract
Objectives: Laryngopharyngeal reflux (LPR) is a complex syndrome characterized by the reflux of gastroduodenal contents into the pharynx or larynx, resulting in a range of symptoms, including chronic cough, throat clearing, pain, dysphagia, hoarseness, and dysphonia. Despite the lack of a gold standard for diagnosis or treatment, various strategies have been proposed to manage LPR. However, the effectiveness of these treatments is compromised by the lack of a uniform treatment protocol, which places a burden on patients, physicians, and the healthcare system. This study aims to systematically review the treatments of LPR and provide updated and useful clinical information to clinical physicians. Methods: The literature with an emphasis on LPR and related keywords is searched and reviewed in PubMed. Results: Treatment of LPR includes health education, lifestyle modification, dietary changes, medications, and surgery, as well as the emergence of a novel treatment method involving external upper esophageal sphincter compression devices. Conclusions: Currently, medication is the main treatment, supplemented with lifestyle and dietary changes, but there is still a lack of effective means for patients with drug-resistant or intolerant LPR. More high-quality and rigorous trials must continue to be conducted to determine the best treatment options and find novel treatments. Taking into account the complexity of LPR, this study proposes a simple algorithm to help clinicians with the initial management of this disease.

Abstract
Laryngopharyngeal reflux (LPR) is a variant of gastroesophageal reflux disease (GERD) in which gastric refluxate irritates the lining of the aerodigestive tract and causes troublesome airway symptoms or complications. LPR is a prevalent disease that creates a significant socioeconomic burden due to its negative impact on quality of life, tremendous medical expense, and possible cancer risk. Although treatment modalities are similar between LPR and GERD, the diagnosis of LPR is more challenging than GERD due to its non-specific symptoms/signs. Due to the lack of pathognomonic features of endoscopy, mounting evidence focused on physiological diagnostic testing. Two decades ago, a dual pH probe was considered the gold standard for detecting pharyngeal acidic reflux episodes. Despite an association with LPR, the dual pH was unable to predict the treatment response in clinical practice, presumably due to frequently encountered artifacts. Currently, hypopharygneal multichannel intraluminal impedance-pH catheters incorporating two trans-upper esophageal sphincter impedance sensors enable to differentiate pharyngeal refluxes from swallows. The validation of pharyngeal acid reflux episodes that are relevant to anti-reflux treatment is, therefore, crucial. Given no diagnostic gold standard of LPR, this review article aimed to discuss the evolution of objective diagnostic testing and its predictive role of treatment response.

Abstract
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.

Abstract
Laryngopharyngeal reflux (LPR) is a syndrome caused by reflux of gastric contents into the pharynx or larynx, which leads to symptoms of throat clearing, hoarseness, pain, globus sensation, cough, excess mucus production in the throat, and dysphonia. LPR is a challenging condition, as there is currently no gold standard for diagnosis or treatment, and thus this presents a burden to the healthcare system. Strategies for treatment of LPR are numerous. Medical therapies include proton pump inhibitors, which are first line, H2 receptor antagonists, alginates, and baclofen. Other noninvasive treatment options include lifestyle therapy and the external upper esophageal sphincter compression device. Endoscopic and surgical options include antireflux surgery, magnetic sphincter augmentation, and transoral incisionless fundoplication. Functional laryngeal disorders and laryngeal hypersensitivity can present as LPR symptoms with or without gastroesophageal reflux disease. Though there are minimal studies in this area, neuromodulators and behavioral interventions are potential treatment options. Given the complexity of these patients and numerous available treatment options, we propose a treatment algorithm to help clinicians diagnose and triage patients into an appropriate therapy.
