Treatment of a Case with Dysphonia Due to Large Posterior Glottal Chink Using Arytenoid Adduction and Type I Thyroplasty

;;;;

ABSTRACT

Surgical treatment options of symptomatic unilateral vocal fold paralysis are Teflon injection, type Ⅰ thyroplasty, and arytenoid adduction. Arytenoid adduction is preferable to type Ⅰ thyroplasty for correcting the level different that may be present between two vocal folds and the large glottal chink However there is no known therapeutic modality effective to correct the large posterior glottal chink of the vocal fold with relatively normal mobility. Recently we have experienced a case of severe large posterior glottal chink of the vocal 1314s with relatively normal mobility after thyroid lobectomy, successfully treated with type Ⅰ thyroplasty combined with arytenoid adduction.
