Synthetic, Multi-Layer, Self-Oscillating Vocal Fold Model Fabrication

Abstract:
Sexual reassignment surgery for individuals with gender identity confusion has been highly successful, especially in the male-to-female transformation. A troublesome problem for some of these individuals is the retention of their male voice. Although castration and estrogen therapy may produce minor elevations of pitch and the assumption of a falsetto voice produces a more typical but contrived female tone, the basic male anatomic structure of the larynx must be altered to effect a physiological transformation. In three transsexuals, an attempt was made to effect a more female tonal quality by shortening the vibrating length of the vocal folds. Through a laryngofissure, the anterior one third of each cord was denuded and the raw edges approximated. This produced an anterior web that successfully resulted in pitch elevation in all three cases.

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...

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...
