Laryngectomy is the removal of the larynx. In a total laryngectomy, the entire larynx is removed (including the vocal folds, hyoid bone, epiglottis, thyroid and cricoid cartilage and a few tracheal cartilage rings) with the separation of the airway from the mouth, nose and esophagus. [1] In a partial laryngectomy, only a portion of the larynx ...
The lateral process is the attachment of one of the major intrinsic muscles of the vocal folds and consequently named the muscular process. [ 1 ] As the concave bases of the arytenoid cartilages move on the two convex articular surfaces on the cricoid cartilage (at the cricoarytenoid articulations ), the vocal processes are brought closer to ...
The body of the hyoid bone is the central part of the hyoid bone. [clarification needed]At the front, the body is convex and directed forward and upward. It is crossed in its upper half by a well-marked transverse ridge with a slight downward convexity, and in many cases a vertical median ridge divides it into two lateral halves.
Their outer edges are attached to muscle in the larynx while their inner edges form an opening called the rima glottidis. They are constructed from epithelium, but they have a few muscle-fibres in them, namely the vocalis muscle which tightens the front part of the ligament near to the thyroid cartilage. They are flat triangular bands and are ...
Mandibulectomy is the removal of the mandible or the lower jaw bone. Mastectomy is the surgical removal of one or both breasts. A mastectomy can be either partial or complete. Mastoidectomy is the removal of mastoid process. Maxillectomy is the removal of the maxilla or cheekbone. This can sometimes be done with orbital exenteration (removal of ...
Hyaline cartilage is the most common kind of cartilage in the human body. [2] It is primarily composed of type II collagen and proteoglycans. [2] Hyaline cartilage is located in the trachea, nose, epiphyseal plate, sternum, and ribs. [2] Hyaline cartilage is covered externally by a fibrous membrane known as the perichondrium. [2]
The Sistrunk procedure is the surgical resection of the central portion of the hyoid bone along with a wide core of tissue from the midline area between the hyoid and foramen cecum. [12] It involves excision not only of the cyst but also of the path's tract and branches, and removal of the central portion of the hyoid bone is indicated to ...
In the human larynx, the cuneiform cartilages (from Latin: cuneus 'wedge' + forma 'form'; also known as cartilages of Wrisberg) are two small, elongated pieces of yellow elastic cartilage, placed one on either side, in the aryepiglottic fold. [1] The cuneiforms are paired cartilages that sit on top of and move with the arytenoids. [2]
