In 1978, Drs. Singer and Blom pioneered the methods of tracheoesophageal puncture and valved silicone voice prostheses that over the past 30 years have become the international standard for voice restoration, allowing thousands of patients worldwide to regain their ability to speak. By creating a small surgical passage just inside the stoma, from the back wall of the trachea into the esophageal wall, a voice prosthesis can be placed into this passage to enable tracheoesophageal speech. Voice is produced by temporarily blocking the stoma so that exhaled air from the lungs can be directed from the trachea through the prosthesis into the esophagus and then out through the mouth. Fluent, conversational speech may be acquired within just a few days.

Blom-Singer voice prostheses are available as patient-maintained (ex: Duckbill, Low Pressure) or clinician-maintained (ex: Indwelling). Standard products are designed to accommodate most anatomies; special order product size/styles are also available.

Clinician-placed Indwelling Voice Prostheses

The Blom-Singer Indwelling voice prosthesis is an indwelling style, clinician-placed voice prosthesis. The product is designed for laryngectomees who are unable or unwilling to routinely remove, clean, and reinsert a patient-changeable voice prosthesis.

Blom-Singer Indwelling voice prostheses are available in four product styles and offered in nonsterile or sterile, and with or without silver oxide (anti-fungal substance). Nonsterile product is not intended for primary placement procedures.

Blom-Singer Indwelling Voice Prostheses Nonsterile Sterile Silver Oxide
CLASSIC, 16 & 20 Fr. X X
ADVANTAGE (Hard Valve Assembly) 20 Fr. X X
ADVANTAGE (Soft Valve Assembly) 16 & 20 Fr. X X

*Silver oxide, a known anti-fungal substance, has been incorporated into the prosthesis as a material preservative. This feature may eliminate or reduce the need for anti-fungal agents such as Nystatin for some users, but not for others.

Blom-Singer ADVANTAGE Indwelling Voice Prosthesis - Rx

The ADVANTAGE indwelling voice prosthesis is the newest advancement in Blom-Singer voice restoration. Silver oxide has been incorporated into the prosthesis as a material preservative. The ADVANTAGE is placed by the clinician in the tracheoesophageal puncture so that routine changing of a voice prosthesis is unnecessary. It is ideal for laryngectomees who are unable or resistant to changing a removable voice prosthesis, such as the Duckbill or Low Pressure styles. The ADVANTAGE is inserted and replaced on an as needed basis by a speech pathologist or physician only.

Available in two diameter sizes, 16 Fr. and 20 Fr., and a range of lengths from 4 mm to 22 mm. Includes nonsterile voice prosthesis for secondary/replacement procedures; with insertion/cleaning accessories.

Blom-Singer CLASSIC Indwelling Voice Prostheses

Since its introduction in 1994, the Blom-Singer Classic Indwelling voice prosthesis has been a premier voice restoration product for laryngectomees worldwide. Like the ADVANTAGE Indwelling voice prosthesis, the Classic indwelling is intended for laryngectomees who are unable or reluctant to perform the routine removal and insertion necessary for the cleaning and maintenance of traditional, patient-maintained voice prostheses. The Classic Indwelling voice prosthesis is clinician placed; it is inserted and replaced on an as needed basis by a speech pathologist or physician only. It is available in a variety of sizes and styles.

Introducing the FIRST ever 16 Fr. Indwelling Voice Prosthesis!
According to Eric D. Blom, Ph.D.,* he considers the use of a 16 Fr. Indwelling voice prosthesis in the following circumstances:

  • As the initial voice prosthesis following tracheoesophageal puncture.
  • Patients who have questionably healthy tracheoesophageal wall tissue, i.e., post-radiation or chemo-radiation therapy, poorly controlled diabetes, or others in who dilating the puncture to 20 Fr. or larger seems unwarranted.
  • Patients with a smaller diameter tracheostoma that will not comfortably accommodate a 20 Fr. or larger diameter prosthesis.
  • Patients with a thin tracheoesophageal wall, i.e., 6mm or less.

* Eric D. Blom, Ph.D. of CENTA - The Center for Ears, Nose, Throat & Allergy, Indianapolis, has many years of clinical experience in Surgical Voice Restoration. According to Dr. Blom, a 16 Fr. Indwelling Voice Prosthesis should only be used in a 16 FR. diameter Tracheoesphageal Puncture.
