Larynx01:21

Larynx

6.3K
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

955
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...

Area of Science:

  • Otolaryngology
  • Surgical Anatomy
  • Regenerative Medicine

Background:

  • Current techniques for adult cricotracheal reconstruction are suboptimal.
  • The thyroid ala perichondrial flap presents a novel approach for airway reconstruction.

Purpose of the Study:

  • To investigate the anatomical basis of the thyroid ala perichondrial flap.
  • To describe the harvesting and intraluminal placement technique.
  • To determine the limitations of defects addressable by this flap.

Main Methods:

  • A cadaveric anatomical study was conducted using fresh specimens.
  • The perichondrium of the thyroid cartilage ala was elevated to create an inferiorly based flap.
  • Flap coverage extent was measured after intraluminal placement through the cricothyroid membrane.

Main Results:

  • Ten flaps were performed in cadavers (6 male, 4 female).
  • Average flap length was 1.67 cm, covering the cricoid cartilage and extending to the first tracheal ring.
  • Intraluminal placement covered up to 2.4 cm below the vocal cords, with bilateral flaps covering 180 degrees of the anterior airway.

Conclusions:

  • The thyroid ala perichondrial flap is technically feasible for cricotracheal reconstruction.
  • This flap can cover anterior airway defects up to approximately 2.4 cm below the vocal cords.
  • It offers a method for transferring vascularized tissue to aid in reconstructive procedures.
