한국인 후두의 기능해부학적 고찰

Background: Phonosurgery for vocal cord paralysis such as thyroplasty has been developed but the literatures regarding to the anatomical analysis of Korean laryngeal framework is rare.

Objective: The purpose of this study is to get quantified anatomical data of Korean larynx which would be useful for laryngeal framwork surgery.

Materials and Methods: Forty four anatomical parameters for Korean larynx from 36 male and 15 female cadavers were investigated by modification of Hiramoto's research(1977).

Results: Various anatomical parameters including the level of anterior commissure and vocal cord, angle of thyroid lamina, distance between thyroid notch and lower border of thyroid cartilage, thickness of thyroid cartilage, length of vocal cord, distance between anteroinferior midpoint of thyroid cartilage and crossing point with cricoid cartilage, anteroposterior diameter of cricoid cartilage, distance between apex of arytenoid cartilage and root of vocal process, and location of muscular process were identified.

Conclusion: We believed that it is very important to remind the detailed statistical anatomy of laryngeal framework, in order to achieve successful results in phonosurgery. And we wish to accumulate more data in the future.
