  1. Tracheoesophageal Prosthesis By Mimi Kimmet and Stephanie Smith

  2. What is a Tracheoesophageal Prosthesis (TEP)? • A TEP is a one way valve inserted through the tracheostoma and placed between the posterior tracheal wall and the anterior esophageal wall (Wetmore et. al, 1985). • The TEP diverts the airflow from the lungs through the trachea and into the esophagus, allowing the laryngectomee patient to produce voice (Singer and Blom, 1980).

  3. INDWELLING Can stay in place for 3-6 months Requires SLP to remove/replace Less maintenance required Must have 2cm or greater tracheostoma Must pass esophageal insufflation test NONINDWELLING Must be removed every 3-4 days Patient can change prosthesis independently More education is required for removal, cleaning ,etc. Must have 2cm or greater tracheostoma Must pass esophageal insufflation test Types of TEP’s

  4. NON INDWELLING Blom-Singer Prosthesis and insertion tool

  5. INDWELLING Low pressure InHealth prosthesis and insertion tool with gel caps

  6. OUR STUDY The purpose of our study was to size and fit a TEP. Vocal characteristics of a sustained /i/ were obtained and measured with the patients old TEP, his new TEP, and while using esophageal speech.

  7. Step 1: Removal of Old TEP • Hemos were used to clamp and lock onto the TEP • The TEP was gently pulled outward

  8. Step 2: Insertion of Catheter • Upon removal of the patients old indwelling TEP, a catheter was immediately inserted • The purpose of the catheter was to expand the width of the puncture and to keep the site open for new TEP insertion

  9. Step 3: Measuring • A measuring tool was inserted into the puncture site to determine the size of prosthesis used in fitting

  10. Step 4: Insertion of Non-indwelling TEP • A 1.8cm Duckbill Blom-Singer voice prosthesis was inserted into the puncture site. • Surgi-lube was used to aid in the ease of insertion • The Duckbill was removed and immediately replaced

  11. Step 5: Insertion of Indwelling TEP • A Blom-Singer Low Pressure indwelling prosthesis was inserted into the puncture site. • A gel cap was used to provide aid in insertion, which dissolved within seconds, allowing the prosthesis to expand and adhere to the anterior esophageal wall • The insertion flap was then removed by cutting it off with scissors

  12. Visual Representation of Esophageal Voice

  13. Visual Representation of Old TEP Voice

  14. Visual Representation of New TEP Voice

  15. A comparison of pitch measures

  16. A comparison of voiced energy

  17. Cycle to cycle changes in intensity

  18. What We Found: • Overall there were no significant differences between the old TEP, new TEP, and esophageal speech. • Although the intensity measures with esophageal voicing were the lowest, this was the patients preferred method of voicing. • Fitting of the TEP was much easier than we expected and required a minimal amount of time to complete.
