Rehabilitation of voice and speech after laryngectomy with valve prosthesis has become a well-established practice in recent years. The formation of tracheo-oesophageal fistula (TOF) and the subsequent management of the patient with a voice prosthesis can be associated with a number of problems and complications.We report a new technique of the use of injectable Bioplastique® in the treatment of persistent leakage around Provox® 2 voice prosthesis. Our experience in two cases has shown that it is a relatively simple and effective procedure in stopping the leak around the valve immediately and is without any short-term complications.

Voice And Speech

Rehabilitation of voice and speech after total laryngectomy has become established practice in recent years. A voice prosthesis is placed within a surgically produced fistula between the trachea and upper oesophagus and acts as a one way valve, allowing passage of pulmonary air from the trachea into the oesophagus and preventing aspiration of food and fluid from the oesophagus into the trachea. Persistent leakage through or around these prostheses is a recognized complication, the aetiology of which can vary widely, from mechanical issues with the prostheses themselves to anatomical and physiological issues associated with the reconstructed pharynx.We report a new technique of using Dysport® in the management of intractable central leakage due to premature and forceful closure of the upper oesophageal sphincter during swallowing. This resulted in the pooling of fluids around the posterior flange of the prosthesis. This, along with the increased pressure from the muscle contraction, led to central leakage, as identified on videofluoroscopy. An injection of Dysport paralysed the upper oesophageal sphincter, preventing pooling of fluids around the prosthesis and the forcing open of the valve. The effect was to eliminate the leakage, and the patient did not require further injections over the following 22 months.
