Abstract:
The arterial basis of pharyngeal flaps is unknown. Injection and dissection studies have been used in 41 adult human cadavers to study the arterial supply of pharyngoplasties in current use. Superiorly based posterior pharyngeal flaps are "random" in nature, inferiorly based posterior pharyngeal flaps may include an "axial" vessel, laterally based posterior pharyngeal flaps will include an "axial" vessel, and laterally based "sphincter" pharyngoplasties, although supplied segmentally, will contain an "axial" vessel if raised up to but not beyond the upper pole of the tonsil.

Pharynx
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Larynx
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...
