[Modified type I thyroplasty for treating unilateral vocal cord paralysis].

Objective: To explore a new surgical approach for treating unilateral vocal cord paralysis.

Methods: Five cases of unilateral vocal cord paralysis due to various causes were treated with modified type I thyroplasty. Laryngostroboscopy and electroglottography were performed before and after the operations.

Results: The vocal cords were shifted very close to the median line in all the 5 cases postoperatively as shown by laryngostroboscopy and electroglottography. Complete closure of the glottis was achieved. The patients had almost normal results of electroglottography, and the vocal sound nearly recovered normal or was significantly improved.

Conclusion: Modified type I thyroplasty is effective, safe and easy in treating unilateral vocal cord paralysis.
