Larynx01:21

Larynx

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...
The Hyoid Bone01:12

The Hyoid Bone

The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Mechanism of Breathing III: The Accessory Muscles

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...
Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques01:30

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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 interventions are...
Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract.

Area of Science:

  • Otolaryngology
  • Surgical Anatomy
  • Vocal Fold Surgery

Background:

  • Arytenoid adduction is effective for vocal fold medialization in paralysis.
  • Current techniques face challenges with arytenoid access and potential morbidity.
  • This study addresses the need for anatomical data to optimize surgical approaches.

Purpose of the Study:

  • To provide anatomical data on arytenoid cartilage accessibility via a thyroplasty window.
  • To assess the feasibility of arytenoid adduction using screw fixation through this window.
  • To establish morphometric relationships for surgical planning.

Main Methods:

  • Dissection and measurement of 10 human cadaver larynges (6 female, 4 male).
  • Anchoring a surgical screw with suture to the fovea oblonga of the arytenoid cartilage.
  • Evaluation of distances from the thyroplasty window to the arytenoid.

Main Results:

  • Mean distance from the thyroplasty window to the arytenoid was 8-9 mm (males) and 7-8 mm (females).
  • No significant gender-based differences were observed in these critical distances.
  • Medialization of the posterior vocal fold was achieved by pulling the anchored screw.

Conclusions:

  • A consistent morphometric relationship exists between the thyroplasty window and arytenoid cartilage.
  • The fovea oblonga is identified as an optimal fixation point for surgical screws.
  • This approach facilitates arytenoid medialization through a conventional thyroplasty window.
