Larynx01:21

Larynx

2.7K
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,...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

210
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

504
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...

Cardiopulmonary Resuscitation II: ACLS Airway Management

253
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Area of Science:

  • Otolaryngology
  • Phonosurgery
  • Laryngeal Framework Surgery

Background:

  • Laryngeal framework surgery encompasses phonosurgical procedures modifying the larynx's cartilaginous structure.
  • These surgeries aim to adjust vocal fold position and tension for voice improvement.

Purpose of the Study:

  • To discuss laryngeal framework surgery, focusing on thyroplasty type 1 (medialization thyroplasty).
  • To highlight the indication of medialization thyroplasty for glottic insufficiency.

Main Methods:

  • Review of phonosurgical procedures within laryngeal framework surgery.
  • Focus on thyroplasty type 1 (medialization thyroplasty) as a key example.

Main Results:

  • Medialization thyroplasty is the most recognized procedure for glottic insufficiency.
  • The first successful medialization thyroplasty was performed over a century ago.

Conclusions:

  • Laryngeal framework surgery offers voice improvement through vocal fold modification.
  • Medialization thyroplasty, despite its efficacy and history, remains underutilized in Germany.
