BACKGROUND A pneumatic artificial sound source incorporated in a regular tracheoesophageal shunt valve may improve alaryngeal voice quality. METHODS In 20 laryngectomees categorized for sex and pharyngoesophageal segment tonicity, a prototype sound-producing voice prosthesis (SPVP) is evaluated for a brief period and compared with their regular tracheoesophageal shunt speech. RESULTS Percep...

OBJECTIVE To examine the effect of a new surgical intervention, consisting of cricopharyngeal myotomy and tracheal cartilaginous implantation on the anterior wall of the esophagus, for tracheoesophageal shunt and esophageal phonation. DESIGN We examined the vibration of the neoglottis of tracheoesophageal shunt and esophageal speakers after total laryngectomy using a high-speed video camera (...

Vo ice rehabilitation after total laryngectomy Vo ice rehabilitation after total laryngectomy using the ProvoxTM voice prosthesis Chemoprophylaxis of fungal deterioration of the Provox™ silicone tracheoesophageal prosthesis in postlaryngectomy patients Deterioration of the ProvoxTM tracheoesophageal voice prosthesis: microbial aspects and structural changes Cineradiography...

The most common surgical procedure used to manage tracheoesophageal fistula is the primary anastomosis of the esophagus. However, in the case of failed anastomosis, replacing the esophagus with another organ is necessary. We performed two procedures of colon interposition after failure of tracheoesophageal fistula repair. In those cases, stomach replacement was not possible because of a failed ...

BACKGROUND After total laryngectomy and voice rehabilitation using a tracheoesophageal shunt valve, patients often have valve-related complications such as leakage. To solve these problems, a tracheoesophageal tissue connector (TE-TC) was devised to serve as an interface between the patient's tissue (trachea and esophagus) and the shunt valve. METHODS The TE-TC is a permucosal connection cons...

Nowadays tracheoesophageal voice prosthesis after total laryngectomy are widely used. Data on maximum phonation time and spectrum have been studied by different authors and are well known. On the contrary pitch control did not received much attention. Pitch has an important role not only in singing but also in the prosodic characteristics of speech. To our knowledge pitch variations have been s...

Background: rehabilitation of individuals with total laryngectomy. Aim: to correlate the voice and speech proficiency of individuals with total laryngectomy, users of tracheoesophageal, prosthesis with the intraluminal pharyngoesophageal transition pressure at rest and during phonation. Method: twelve individuals with total laryngectomy and with tracheoesophageal voice, users of speech prosthes...

OBJECTIVES The objective of this study was to determine the rates of nasalance for total laryngectomized users of a tracheoesophageal voice prosthesis and correlate them with the findings of auditory-perceptual assessment of nasality. METHODS In this study, 25 total laryngectomized users, including 20 men and five women, with a mean age of 63 years old participated. All the participants had a...
