Project description:Since severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was noted to cause coronavirus disease 2019 (COVID-19) in 2019, there have been many trials to develop vaccines against the virus. Messenger ribonucleic acid (mRNA) vaccine as a type of the vaccine has been developed and commercialized rapidly, but there was not enough time to verify the long-term safety. An 82-year-old female patient was admitted to the emergency room with dyspnea accompanied by stridor three days after the 3rd COVID-19 mRNA vaccination (Comirnaty, Pfizer-BioNTech, USA). The patient was diagnosed with bilateral vocal fold paralysis (VFP) by laryngoscope. Respiratory distress was improved after the intubation and tracheostomy in sequence. The brain, chest, and neck imaging tests, serological tests, cardiological analysis, and immunological tests were performed to evaluate the cause of bilateral VFP. However, no definite cause was found except for the precedent vaccination. Because bilateral VFP can lead to a fatal condition, a quick evaluation is necessary in consideration of VFP when dyspnea with stridor occurs after vaccination.

Project description:RationaleArytenoid dislocation is very rare and may be misdiagnosed as vocal cord paralysis or a self-limiting sore throat.Patient concernsA 70-year-old male (70 kg, 156 cm) was scheduled for transurethral resection of bladder tumors. A McGrath videolaryngoscope, with a basic cuffed Mallinckrodt oral tracheal tube of 7.5 mm internal diameter, was used to successfully intubate his trachea. The duration of surgery was 25 minutes. In the recovery room, he complained of sore throat and dyspnea with inspiratory stridor, which were not resolved after intravenous injection of 10 mg of dexamethasone.DiagnosesThe otolaryngological examination revealed midline fixation of the bilateral vocal folds, suggestive of bilateral arytenoid dislocation or bilateral vocal cord palsy. The latter was ruled out because there was no evidence of recurrent laryngeal nerve injury.InterventionsUnder general anesthesia, a closed reduction was performed using laryngoscopic forceps to apply posterolateral pressure on the arytenoid joints on both sides. Only the dislocation of the left cricoarytenoid joint could be easily reduced, whereas reduction of the right joint was not possible.OutcomesOn postoperative day 7, examination with a rigid laryngoscope showed a medially fixed right vocal fold, with full compensation by the left vocal fold. Computed tomography of the neck showed no pathologic findings. Six weeks after surgery, the patient had regained his normal voice with no complications.LessonsAlthough arytenoid dislocation is a rare complication, it should be considered even in patients with uncomplicated tracheal intubation. Early diagnosis and the optimal therapeutic approach are critical for restoration of the patient's original vocal cord function.

Project description:Cranial neuropathy is a clinical manifestation of meningeal carcinomatosis (MC); however, the glossopharyngeal and vagus nerves are rarely impaired. Therefore, dysphagia and bilateral vocal cord paralysis (BVCP) are extremely rare manifestations of MC. Here, we present a case of MC from a lung adenocarcinoma presenting with dysphagia and BVCP. An 84-year-old man with a 4-year history of left lung adenocarcinoma developed dysphagia and hoarseness. Flexible nasopharyngoscopy revealed BVCP. Ten days later, the patient developed stridor and respiratory distress. A tracheotomy was performed to prevent airway obstruction. Gadolinium-enhanced magnetic resonance imaging (MRI) of the brain showed enhancement of the bilateral glossopharyngeal and vagus nerves, and several enhancing lesions in the right internal auditory canal, left cerebellum, fourth ventricle, pons, cerebral aqueduct, and right frontal lobe, suggesting MC and brain metastasis. Based on the clinical history of malignancy and the MRI findings, the patient was diagnosed with MC. As the patient refused additional treatment, including chemotherapy and radiation, only palliative care was provided. To the best of our knowledge, this was the first case of MC from a solid tumor presenting with BVCP. When patients with malignancy present with BVCP, MC should be considered.

Project description:Purpose of reviewPresent the state-of-the-art overview of laryngeal pacing for treatment of bilateral vocal fold paralysis. A minimally invasive unilateral pacing system and a fully implantable bilateral pacing system are currently in clinical trials. The relative advantages and disadvantages of each are discussed.Recent findingsResearch in functional electrical stimulation for the reanimation of the posterior cricoarytenoid muscle has successfully translated from animal models to human clinical trials for unilateral pacing and bilateral pacing. Current findings suggest unilateral pacing in humans significantly improves ventilation but only marginally better than cordotomy. Bilateral pacing in canines increases glottal opening greater than 2-fold over unilateral pacing and restores exercise tolerance to normal.SummaryUnilateral pacing can be considered a breathing assist device and may not be appropriate for active individuals. Bilateral pacing may be preferable for patients who wish to engage in strenuous exercise. Minimally invasive systems may be ideal for patients who prefer less invasive implantation and are not concerned with cosmesis. Fully implantable pacing systems offer greater electrode redundancy and stability, resulting in a system that is robust against electrode migration or damage.

Project description:Idiopathic bilateral vocal cord paralysis (VCP) is a rare and difficult condition often undiagnosed and frequently confused with asthma and other respiratory conditions. Accurate diagnosis is crucial since 80% of cases patients require surgical intervention, such as tracheostomy or laser surgery, to relieve symptoms. The "gold standard" for diagnosing VCP has been laryngoscopy. In this case study, we demonstrate for the first time that idiopathic bilateral VCP can be accurately diagnosed by means of a novel noninvasive methodology: dynamic volume 320-slice computed tomography larynx. Three-dimensional reconstruction of laryngeal motion during the breathing cycle permitted functional assessment of the larynx showing absence of vocal cord movements. The new methodology may be valuable for noninvasive diagnosis of vocal cord movement disorders before and for follow-up after surgery.

Project description:Charcot-Marie-Tooth disease is a heterogeneous group of inherited distal symmetric polyneuropathies associated with mutations in genes encoding components essential for normal functioning of the Schwann cell and axon. TRIM2, encoding a ligase that ubiquitinates the neurofilament light chain, was recently associated with early-onset neuropathy in a single patient. We report a TRIM2 homozygous missense mutation (c.2000A>C; p.D667A) in a patient with peripheral neuropathy and bilateral vocal cord paralysis, allowing for further delineation of the associated phenotypic spectrum.

Project description:ObjectivesTo determine the decannulation rate (DR) and revision surgery rate after surgery for bilateral vocal fold paralysis (BVFP).Data sourcesFive databases (MEDLINE, PubMed, Embase, Web of Science, Scopus) were searched for the period 1908-2020.MethodsThe systematic literature review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were pooled using a random-mixed-effects model. Randomized controlled trials and non-randomized studies (case-control, cohort, and case series) were included to assess DR and revision surgery rate after different surgical techniques for treatment of BVFP.ResultsThe search yielded 857 publications, of which 102 with 2802 patients were included. DR after different types of surgery was: arytenoid abduction (DR 0.93, 95%-confidence interval [CI], 0.86-0.97), endolaryngeal arytenoidectomy (DR 0.92, 95%-CI, 0.86-0.96), external arytenoidectomy (DR 0.94; 95%-CI, 0.71-0.99), external arytenoidectomy and lateralisation (DR 0.87; 95%-CI, 0.73-0.94), laterofixation (DR 0.95; 95%-CI, 0.91-0.97), posterior cordectomy (DR 0.97, 95%-CI, 0.94-0.99), posterior cordectomy and arytenoidectomy (DR 0.98, 95%-CI, 0.93-0.99), posterior cordectomy and subtotal arytenoidectomy (DR 0.98, 95%-CI, 0.88-1.00), posterior cordotomy (DR 0.96, 95%-CI, 0.84-0.99), reinnervation (0.69, 95%-CI, 0.12-0.97), subtotal arytenoidectomy (DR 1.00, 95%-CI, 0.00-1.00) and transverse cordotomy (DR 1.0, 95%-CI, 0.00-1.00). No significant difference between subgroups for DR could be found (Q = 15.67, df = 11, p = 0.1540). The between-study heterogeneity was low (τ2 = 2.2627; τ = 1.5042; I2 = 0.0%). Studies were at high risk of bias.ConclusionBLVP is a rare disease and the study quality is insufficient. The existing studies suggest a publication bias and the literature review revealed that there is a lack of prospective controlled studies. There is a lack of standardized measures that takes into account both speech quality and respiratory function and allows adequate comparison of surgical methods.

Project description:Pleuroparenchymal fibroelastosis (PPFE) is a rare interstitial lung disease that is characterized by predominant upper lobe fibrosis and pleural thickening. In this report, we present an unusual case of idiopathic PPFE with left vocal cord paralysis that developed repeated aspiration pneumonia. Vocal cord paralysis is a rare complication of PPFE, and two mechanisms can be proposed: 1) Fibrous adhesion of the recurrent laryngeal nerve to the chest wall can cause stretching of the nerve. 2) Traction or compression of the recurrent laryngeal nerve due to the distortion of the tracheobronchial tree can cause paralysis of the vocal cord. Finally, to reduce the risk of aspiration pneumonia, laryngoscopic evaluation of the vocal cord is recommended in patients with PPFE with hoarseness and dysphagia for early intervention.

Project description:To prevent severe and potentially life-threatening consequences of bilateral vocal fold paralysis (BVFP), the identification and management of reversible causes is pivotal. Myasthenia gravis (MG) presenting with BVFP is rarely reported and remains incompletely understood. Although symptom control is achievable for most MG patients with sufficient therapy, atypical clinical presentation such as BVFP might preclude diagnosis and thus effective treatment. Here, we present a case of BVFP as leading manifestation of MG successfully treated with plasmapheresis. Moreover, we performed a literature review of the few existing cases reported between 1980 and 2020 indicating that elderly patients are particularly at risk for MG presenting with severe BVFP and that edrophonium testing with fiber optic endoscopic evaluation of swallowing (FEES) might be valuable for establishing the diagnosis. We conclude that clinicians should consider MG as possible and reversible cause for BVFP.
