Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

516
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

787
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...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

709
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Larynx01:21

Larynx

4.2K
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,...

Endoscopic Studies II: Thoracocentesis

1.2K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Area of Science:

  • Otolaryngology
  • Speech Pathology
  • Virology

Background:

  • Post-COVID-19 condition frequently involves dysphonia.
  • Assessing voice disorders and treatment response in isolated post-COVID-19 dysphonia is crucial.

Purpose of the Study:

  • To evaluate objective and subjective voice disorders in patients with isolated post-COVID-19 dysphonia.
  • To assess short-term responses to a multimodal therapy regimen.

Main Methods:

  • Retrospective, single-center pre-post study of 14 patients with isolated post-COVID-19 dysphonia.
  • Standardized assessment included patient-reported outcomes (VHI, V-RQOL) and instrumental laryngeal analysis (LVS, HSV with kymography).
  • Multimodal therapy involved systemic/inhaled corticosteroids, hyaluronic acid, and voice therapy.

Main Results:

  • Baseline HSV revealed glottal insufficiency (irregular motion, reduced amplitude/pliability, disrupted mucosal wave, increased open quotient).
  • Follow-up HSV showed improved oscillation, amplitude, regularity, and reduced asymmetry; phonovibrograms normalized.
  • Instrumental improvements correlated with better VHI and V-RQOL scores.

Conclusions:

  • Comprehensive ENT evaluation with instrumental laryngeal assessment is recommended for persistent post-SARS-CoV-2 dysphonia.
  • Short-term multimodal management demonstrated positive effects on objective voice measures and patient-reported outcomes.
  • Further controlled studies are needed to confirm these findings.
