For vocal rehabilitation after laryngectomy, various methods have been devised, such as Serafini's or Straffieri's reconstructive laryngectomy or tracheoesophageal shunt operation. These techniques are popular in head and neck surgery, however these methods have several disadvantages for speech because aspiration is sometimes unavoidable. We have developed a surgical technique and have been applying it to laryngectomized patients. The surgical peocedures are as follows: 1. When the hyoid bone is removed with the larynx, only the upper portion of the thyropharyngeal muscle is sutured together, but the lower portion is not. The free margins of the cricopharyngeus muscle are not sutured. 2. When the hyoid bone is not excised, both sternohyoid muscles are interposed btween thyropharyngeal muscles and sutured together with them. In either cases, the mucosae of the hypopharynx is sutured horizontally. Only 40% of laryngectomized patients could speak with esophageal voice after laryngectomy with the routine method. With our technique, more than 80% of the acquired esophageal speech.
