The Hyoid Bone01:12

The Hyoid Bone

2.4K
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...

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

2.1K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

The Thyroid Gland01:23

The Thyroid Gland

4.1K
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...

Larynx01:21

Larynx

1.9K
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,...

Growth of Cartilage and Bone Tissue01:27

Growth of Cartilage and Bone Tissue

3.4K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Cranial Nerves: Types Part II01:22

Cranial Nerves: Types Part II

2.6K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.
Facial Nerve (Cranial Nerve VII)
Cranial nerve VII, or the facial nerve,...

Area of Science:

  • Otorhinolaryngology
  • Head and Neck Surgery
  • Pathology

Background:

  • Laryngeal mass lesions are common in otorhinolaryngology practice.
  • Epithelial neoplasms account for 97% of laryngeal masses, while mesenchymal tumors are rare (0.3-1.0%).
  • The larynx's cartilage-rich structure predisposes it to mesenchymal tumors like chondromas and chondrosarcomas.

Purpose of the Study:

  • To report a rare case of a mesenchymal tumor of the larynx.
  • To discuss the diagnostic challenges and management of such rare laryngeal neoplasms.
  • To share surgical experience in managing a laryngeal mesenchymal tumor with larynx preservation.

Main Methods:

  • Case report of a patient with a laryngeal mesenchymal tumor.
  • Diagnostic evaluation including imaging and biopsy (details not provided in abstract).
  • Surgical management via lateral pharyngotomy for mass excision with laryngeal preservation.

Main Results:

  • The patient presented with a laryngeal mass requiring a tracheostomy for over two years.
  • Surgical excision of the mesenchymal tumor was performed using lateral pharyngotomy.
  • Successful decannulation was achieved within 20 days post-surgery, indicating larynx function preservation.

Conclusions:

  • Mesenchymal tumors, though rare, should be considered in the differential diagnosis of laryngeal mass lesions.
  • Early diagnosis and appropriate surgical intervention, such as lateral pharyngotomy, can lead to successful outcomes with larynx preservation.
  • This case underscores the importance of considering rare pathologies and tailored surgical approaches in head and neck practice.
