Vocal cord dysfunction

The purpose of this study was to clarify changes in cough function in patients with multiple system atrophy (MSA). Seventeen probable patients with MSA were studied. Peak cough flow (PCF), respiratory function (percentage of vital capacity, percentage of forced vital capacity, and percentage of predicted forced expiratory volume in one second), respiratory muscle strength (percentage of maximal inspiratory mouth pressure and percentage of maximal expiratory mouth pressure), and maximum phonation time (MPT) were assessed...

BACKGROUND: The application of intraoperative neurophysiological monitoring (IONM) has been accepted to avoid injury of a recurrent laryngeal nerve (RLN). Loss of the neuromonitoring signal indicates nerve injury and is subdivided into segmental type and global type nerve paralysis. This study aimed to determine the course of vocal cord function recovery after definitive loss of signal (LOS) types. METHODS: This retrospective study included 1,442 patients (with 2,752 nerves at risk) who had thyroidectomies between January 2018 and December 2021...

Introduction: Thermal injury to recurrent laryngeal nerve (RLN) during radiofrequency ablation (RFA) can produce temporary or permanent vocal cord paralysis.1 Hydrodissection with cold 5% glucose of "danger triangle" protects RLN during RFA.2 When RFA is performed under local anesthesia, RLN function is monitored by patients producing vocal sounds.3 Large lesions requiring longer RFAs warrant general sedation where voice cannot be assessed, therefore, an additional technique for RLN protection is advisable...

UNLABELLED: Fiberoptic laryngoscopy is a standard procedure for evaluation of vocal folds immobility. However, this method is invasive, requires special qualifications and technical equipment, which limits its routine use. Therefore, in daily practice, the vast majority of laryngoscopy are performed by an indirect way, the accuracy of which depends on the specialist experience and the patient compliance. On the other hand, a large number of patients require for a convenient, non-invasive and inexpensive approach to assess the vocal folds mobility...

BACKGROUND: Empty sella is an anatomical and radiological finding of the herniation of the subarachnoid space into the pituitary fossa leading to a flattened pituitary gland. Patients with empty sella may present with various symptoms, including headache due to intracranial hypertension and endocrine symptoms related to the specific pituitary hormones affected. Here, we report a female patient who developed persistent postoperative hypotension caused by subclinical empty sella syndrome after a simple surgery...

BACKGROUND: Cricopharyngeal myotomy and laryngeal framework surgery can improve swallowing function in patients with severe dysphagia. We developed a novel surgical technique for severe dysphagia associated with pharyngolaryngeal paralysis and cricopharyngeal dysfunction, performed under local anesthesia, and investigated its effectiveness. METHODS: We included nine patients who underwent cricopharyngeal muscle-origin transection with laryngeal framework surgery through a horizontal skin incision under local anesthesia...

OBJECTIVES: Provide a mixed-methods update on clinical presentation of patients with upper airway dyspnea (UAD). STUDY DESIGN: Prospective, multicenter, mixed-methods study. METHODS: Data were collected from 30 patients presenting to two tertiary ENT clinics with a chief complaint of dyspnea. Exclusionary criteria included abnormal structural laryngeal findings, uncontrolled pulmonary disorders, and medical conditions affecting breathing. Objective data collected included laryngeal exam findings, patient-reported outcome measures and symptom questionnaires, medications, and psychological diagnoses...

OBJECTIVE:  Etiology of vocal cord paralysis (VCP) and laryngeal dysfunction may be congenital or surgical trauma of recurrent and superior laryngeal nerves. We assessed the incidence, risk factors, and morbidity of VCP after repair of esophageal atresia (EA). METHODS:  Medical records of 201 EA patients from 2000 to 2022 were reviewed for this retrospective study. Postrepair vocal cord examination (VCE) included awake nasolaryngeal fiberoscopy by otolaryngologist or laryngoscopy under spontaneous breathing anesthesia...

BACKGROUND: Gastroscopy is one of the most commonly used diagnostic modalities for upper gastrointestinal disorders. This study compared the effect of ciprofol and propofol on swallowing function during painless gastroenteroscopy. METHODS: This was a single-center, placebo-controlled randomized trial. Three hundred sixty-eight patients undergoing painless gastroscopy were included in this study and randomly divided into 2 groups: the propofol group (PRO group, n = 183) and the ciprofol group (CIP group, n = 185)...

A 74-year-old male patient developed multiple infarcts of the brainstem and cerebellum, followed 14 months later by palatal tremor and bilateral vocal cord abduction paralysis, resulting in death due to type 2 respiratory failure. Pathologic analysis revealed old infarcts extending from the bilateral cerebellar cortices to the dentate nucleus, being more extensive on the right side, accompanied by Wallerian degeneration involving the left red nucleus, right central tegmentum tract, and inferior cerebellar peduncle, followed by pseudohypertrophy of the bilateral inferior olivary nuclei...

Chronic cough is a common problem that can be refractory to medical treatment. Nonpharmaceutical management of chronic cough has an important role in well selected patients. This review article outlines the history of chronic cough management, current approaches to speech pathology management of the condition and new modalities of nonpharmaceutical treatment. There is a need for further research into nonpharmaceutical options with well described randomised control trials.

PURPOSE: To compare clinical profiles of pediatric patients with Induced Laryngeal Obstruction (ILO), Exercise Induced Laryngeal Obstruction (EILO), and EILO with non-exertion related secondary triggers (EILO+). METHODS: A retrospective observational cohort design was employed. Four-hundred and twenty-three patients <18 years of age were identified from the electronic medical record of a large children's hospital. All patients underwent evaluations with a laryngologist and speech-language pathologist and were diagnosed with EILO/ILO...

BACKGROUND: The aim of this study was to investigate the associations between individual surgeon's intraoperative nerve monitoring (IONM) practice and factors associated with vocal cord (VC) dysfunction in patients with thyroid cancer undergoing thyroidectomy. METHODS: Using Collaborative Endocrine Surgery Quality Improvement Program (CESQIP) 2014-21 data, multivariable logistic regression analyses investigated variables associated with short- and long-term VC-dysfunction, associations of routine use of IONM with postoperative outcomes, and patient characteristics associated with IONM use...

BACKGROUND: Exercise-induced laryngeal obstruction (EILO) is diagnosed by the continuous laryngoscopy during exercise (CLE) test. Whether or how much CLE test scores vary over time is unknown. This study aimed to compare CLE test scores in athletes over time, irrespective of respiratory symptoms and grade of laryngeal obstruction. METHODS: Ninety-eight athletes previously screened for EILO were invited for a follow-up CLE test irrespective of CLE scores and respiratory symptoms...

BACKGROUND: Laryngomalacia is a dynamic airway condition characterized by flaccid laryngeal tissue and inward collapse of supraglottic structures during inspiration. Although it may cause airway obstruction and requires careful management, there have been few reports regarding laryngomalacia after surgery. We report a case of adult-onset laryngomalacia occurred after craniotomy requiring reintubation. CASE PRESENTATION: A 21-year-old man was admitted to the ICU after craniotomy for a cerebellopontine angle tumor...

BACKGROUND: Vocal cord dysfunction/inducible laryngeal obstruction (VCD/ILO) is characterized by breathing difficulties in association with excessive supraglottic or glottic laryngeal narrowing. The condition is common and can occur independently; however, it may also be comorbid with other disorders or mimic them. Presentations span multiple specialties and misdiagnosis or delayed diagnosis is commonplace. Group-consensus methods can efficiently generate internationally accepted diagnostic criteria and descriptions to increase clinical recognition, enhance clinical service availability, and catalyze research...

BACKGROUND: Individuals with asthma experienced severe and prolonged symptoms following the Australian 2019-2020 landscape fire period. Many of these symptoms, such as throat irritation, are referrable to the upper airway suggesting that laryngeal hypersensitivity contributes to persistent symptoms following smoke exposure. OBJECTIVE: The study examined the relationship between laryngeal hypersensitivity and symptoms, asthma control and health impact in individuals exposed to landscape fire smoke...
