Voice restoration after hemilaryngeal surgery can be achieved by compensatory vocalization through esophageal speech training and speech training of the affected ventricular band.
Hemilaryngeal surgeries involving the vocal folds and resulting in laryngeal vocal dysfunction include: vocal cord resection, vertical partial laryngectomy, supraglottic partial excision of the laryngeal cricoid with a cricoarytenoid epiglottic anastomosis and supraglottic partial excision of the laryngeal cricoid with a cricoarytenoid anastomosis. The symptoms of hoarseness may be noticeable for a period of time after surgery.
Speech rehabilitation training can be started on the 7th to 10th day after surgery, mainly for esophageal speech training and speech training of the affected side of the ventricular band.
1. Esophageal speech training: For patients with total vocal cord resection, try to block the tube and inhale deeply, so that the pharyngeal constrictor muscle contracts to form folds similar to the vocal cords, so that the air enters the esophagus, and then release the gas by belching, so that the folds vibrate and make sounds, which are then processed by the organs of the voice such as the cheeks, the palate, the tongue, the teeth, and the lips, and then become speech.
2. Ventricular band speech training on the affected side: similar to the above method, the ventricular band on the affected side contracts to form folds similar to the vocal folds, and contacts the healthy side’s vocal folds or ventricular bands to form pseudo vocal folds to produce speech.
When the voice is affected after hemilaryngeal surgery, active and standardized speech rehabilitation training can be carried out according to the doctor’s instructions, so that the vocal function can be restored as soon as possible.
