Transoral arytenoid adduction
강의내용
Arytenoid adduction (AA) is a kind of approximation laryngoplasty
for unilateral vocal fold paralysis patients. Main mechanism of the
procedure is vocal fold repositioning by pulling the muscular
process of arytenoid cartilage in the direction of the lateral
cricoarytenoid muscle. AA is especially useful when there is a large
posterior glottal gap, vocal fold level difference, or severely
foreshortened vocal fold, and it can complement the limitation of
type I thyroplasty. Most commonly used AA technique in current
was established by Isshiki. This conventional method requires a 4-5
cm-long skin incision and cutting the inferior pharyngeal
constrictor muscle to approach to the posterior edge of the thyroid
cartilage. Furthermore, to locate and manipulate the muscular
process, excessive rotation of the larynx and dislocation of the
cricothyroid joint or a partial resection of posterior edge of
thyroid cartilage is necessary. These may result in not only
cosmetic problem but also airway or swallowing dysfunction. There
have been some reports focused on the low level of invasiveness and
enhanced feasibility in comparison to conventional AA. However, all
of these methods have been performed on cadaveric or extirpated
larynges and still remain experimental. In this video lecture, a
novel surgical procedure, transoral AA with a minimal cervical
incision is introduced, which decreases the invasiveness of the AA
procedure.
