Summary
A rare anatomical variation revealed bilateral double thyroid foramina in an ossified laryngeal framework. Understanding thyroid cartilage anatomy is crucial for laryngeal surgery to prevent nerve injury.
Area of Science:
- Anatomy
- Laryngology
Background:
- The thyroid foramen in the thyroid cartilage is a known anatomical feature, often transmitting the superior laryngeal neurovascular bundle.
- Variations in its presence and contents can impact surgical procedures.
Observation:
- A unique case of a completely ossified laryngeal framework was identified in a 32-year-old female.
- This specimen exhibited bilateral double thyroid foramina, with three circular and one oval opening.
Findings:
- The observation represents an exceptionally rare anatomical variation of the thyroid cartilage.
- The presence of multiple foramina highlights the potential for significant anatomical variability.
Implications:
- Detailed knowledge of thyroid cartilage anatomy and potential foramina is essential for surgeons performing laryngeal and thyroid procedures.
- Awareness of these variations aids in meticulous dissection, crucial for controlling bleeding and preventing superior laryngeal nerve injury and subsequent neurological complications.

1.7K
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,...

01:23The Thyroid Gland
4.0K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:12The Hyoid Bone
2.3K
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...

01:29Anatomy of Respiratory System I: Upper Respiratory Tract
1.9K
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.

01:27Cranial Bones: Lateral View
2.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:28Tracheostomy: Procedure and Tubes
796
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...
