Laryngoplasty using suprahyoid muscles--hyoid transposition laryngoplasty.

A new technique of laryngoplasty using the function of the suprahyoid muscles (hyoid transposition laryngoplasty) was reported. Total laryngectomy is carried out as usual and the tracheal stump is anastomosed directly to the hypopharynx. The hyoid bone is cut medially, then transpositioned and sutured to the posterolateral margins of the tracheal stump. With this procedure, the new glottis is pressed strongly to the tongue base during swallowing and aspiration is avoided. Postoperative swallowing and speech in the cases operated on with this method were satisfactory, and even nasal respiration was possible in some cases.
