Head and neck anatomy landmarks
Today, Dr. Bailey is back with a video about her approach to head and neck anatomy using landmarks. With this quick video, in about 5 minutes you can learn to quickly differentiate the important anatomical subsites of the head and neck on computed tomography.
0:19 Nasal cavity versus the nasopharynx. The nasal cavity and nasopharynx are both above the hard palate up to the cribriform plate. The nasopharynx begins just behind the posterior margin of the hard palate
1:20 Oral cavity vs oropharynx. Similarly, the oral cavity includes the tissue below the hard palate and anterior to its posterior margin, while the oropharynx includes what is posterior to the margin of the hard palate.
2:30 Floor of the mouth. The floor of the mouth is predominantly made of muscular structures, including the genioglossus, hyoglossus, and mylohyoid.
3:41 Hypopharynx. The hypopharynx consists of the pyriform sinuses, the lateral and posterior pharyngeal walls, and the posterior surfaces of the larynx extending to the cervical esophagus.
4:11 Supraglottic larynx. The supraglottic larynx includes everything from the tip of the epiglottis down to the laryngeal ventricle.
4:45 Larynx-glottis. The glottis includes the larynx and true vocal cords, including the anterior and posterior commissures.
5:17 Larynx-subglottis. The subglottis extends from the inferior aspect of the true vocal cords to the cricoid cartilage. Below the cricoid cartilage is the trachea.
