Conclusion The body of hyoid bone with sternohyoid or omohyoid muscle flap is an ideal material with extensive flexibility in laryngeal function reconstruction after partial laryngectomy.

Muscle relaxant vecuronium bromide reduction group to ensure the smooth progress of the recurrent laryngeal nerve monitoring.
