Brief description/objective

Structural and functional damage of the recurrent laryngeal nerve
(RLN) results in paresis of the PCAM. This causes impairment in
phonation and respiration. Due to the topographic location of the
RLN, lesions occur mostly during interventions on the thyroid gland.
Beside surgical procedures on the vocal ligaments to improve
phonation and respiration, posticus-electrostimulation-techniques
can also be used. A ventral approach through the thyroid cartilage of
the larynx offers a good possibility to reach the PCAM, because the
cartilage is covered only by skin, and infrahyoidal muscles. In order
to elucidate landmarks for the ideal pathway through the cartilage,
we dissected 15 human laryngeal specimens. The obtained results
have been applied in-situ on a specimen.
