Paradoxical vocal fold movement: a case report
Journal of Voice : Official Journal of the Voice Foundation
|September 23, 1997
Summary
This case study shows speech therapy effectively treating respiratory stridor caused by paradoxical vocal fold motion. Recognizing this functional breathing disorder is key for proper diagnosis and management.
Area of Science:
- Otolaryngology
- Pulmonology
- Speech-Language Pathology
Background:
- Respiratory stridor can be a challenging clinical presentation.
- Functional respiratory disorders often mimic organic pathologies.
- Paradoxical vocal fold motion (PVFM) is an underdiagnosed cause of upper airway obstruction.
Observation:
- A patient presented with significant respiratory stridor, wheezing, and dyspnea.
- Flexible fiberoptic videolaryngoscopy revealed paradoxical vocal fold adduction during inspiratory distress.
- Normal vocal fold function was observed during quiet breathing and phonation.
Findings:
- The patient's stridor and dyspnea were successfully resolved with targeted speech therapy.
- This suggests a functional etiology for the observed respiratory symptoms.
- Speech therapy interventions can effectively manage paradoxical vocal fold motion.
Implications:
- Clinicians should consider functional stridor and paradoxical vocal fold motion in the differential diagnosis of respiratory distress.
- Early recognition and appropriate treatment, such as speech therapy, can lead to significant patient improvement.
- Further research into the pathophysiology and treatment of PVFM is warranted.

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:30Respiratory System Abnormal Finding I: Inspection and Percussion
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

01:31Respiratory System Abnormal Finding II: Palpation and Auscultation
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

01:29Suctioning the Nasopharyngeal Airway
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:25Suctioning the Oropharyngeal Airway
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

01:11Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
