In most patients an 8 or 10 millimeter prosthesis is sufficient.

I am an outdoor activity enthusiast, walk/jogging, biking, hiking, and backpacking, so I am very concerned about protecting my stoma from anything but air being inhaled. I don't have a voice prosthesis, which makes protecting my stoma less complicated. You are probably aware that the ways mosquitos home in on us, as a food source, is their acute ability to detect carbon dioxide, oder, temperature, and movement, so we are prime to go items on their menus when we are out rock'in and roll'in. I used the HME baseplate filter system at first, when I was able to get back into action, but I too found them very frustrating and unsatisfactory, because I was always blowing them out with my heavy breathing and sweating. I just happened to have some Humidi-Foam Stoma Filters which I had received a sample of from Bruce Medical Supply at one of the Annual IAL Meeting/Voice Institutes, so I decided to give one a try for a walk/jog, and was delighted to find that it stayed in place without a problem. I do, however, also utilize an UnderArmour (my preferred brand) "compression" shirt, under my usual activity shirt (always made of a technical microfiber material), to hold it securely in place. The reliability of the foam filter was a fabulous discovery for me, and I find that there have only been a few times when the filter adhesive has failed during the past few years and multitude of heavy breathing, sweaty actives for which they have worked without a hitch. I keep a bandana handy in case I am caught in dusty conditions to add an additional layer of filtering.
Tucking the bottom of the bandana into my compression shirt keeps it securely in place. The compression shirt also has the property of wicking moisture away for quicker evaporation, and thus works to help cool the body. Have a great time on your outdoor adventures. I'll be doing a combination bike/hike in the wilds of centralish Florida this weekend which I am very much looking forward to. Happy trails!

Provox® NON-INDWELLING VOICE PROSTHESIS

A total of 157 prostheses were replaced.

3. If you can't stop a leak coming through the prosthesis when you eat or drink, there are now plugs to use to stop up the passage through the prosthesis on a temporary basis untill you can get to your SLP for a change.

The aim of the study was to compare device life of more recent indwelling voice prostheses Provox Vega and Blom-Singer Dual Valve to device life of well-known standard devices (Provox 2, Blom-Singer Classic). In a prospective, non-randomised study, device life of Blom-Singer Classic, Blom-Singer Dual Valve, Provox2, Provox Vega and Provox ActiValve voice prostheses was recorded in a group of 102 laryngectomised patients. In total 749 voice prosthesis were included. Average overall life time was 108 days, median 74 days. The prosthesis with the longest dwell time was the Provox ActiValve (median 291 days). Provox Vega had longer device life compared with Provox2 (median 92 days vs 66 days; p = 0.006) and compared with Blom-Singer Classic (median 92 days vs 69 days; p = 0.004). In conclusion, device lifetimes of Provox Vega and ActiValve were better than those of Provox2 and the Blom-Singer Classic. New voice prostheses, with a defined valve opening pressure (Provox Vega, Provox ActiValve, Blom-Singer Dual Valve) had longer lifetimes than prostheses without a defined opening pressure (Blom-Singer Classic and Provox 2).

Assessment of survival time of 378 Provox‐1, Provox‐2 and Blom‐Singer voice prosthesis.
Prostheses of group 1 were more often colonized with Staphylococcus aureus (p = .027) and Enterobacteriaceae (p = .015).

Step 4. The puncture needs to be fully open to a diameter that is slightly larger in diameter than the prosthesis (eg, 22 French for a 20 French prosthesis) to have an easy insertion. Start with a dilator/stent/catheter that is slightly smaller in diameter than the puncture - it should slide easily in and out of the puncture with a lubricant. Move to successively larger diameter stents/catheters until thedilator that is slightly larger than the diameter of the prosthesis (eg, 22 French for a 20 French prosthesis) slides easily in and out of the puncture tract. That can take hours sometimes, even overnight, but don't rush it. Once it is fully dilated, check that the open tract voicing is good. If it is, the puncture tract length is measured and the correct prosthesis is inserted. If the open tract voice is still not good after you know that the puncture is fully dilated, go to Step 5.

No significant difference in mean prosthesis indwelling time (p = .45) was observed between group 1 (116 ± 114 days) and group 2 (129 ± 99 days).

I had laryngectomee surgery 4/7/05 preceded by radiation for laryngeal cancer in 2001, which was after lung cancer/lobectomy in 1997. I voice with TEP, both manual and hands free.

Four lengths of the Provox voice prostheses are available: 4.5, 6, 8 and 10 millimeters, and two additional lengths of 12.5 and 15 mm of Provox2.

The Blom-Singer Dual Valve has a silicone housing and two silicone flap valves containing 7 % of silveroxide mixed into the silicone, one on the oesophageal side, and an additional one on the tracheal side. The double valve is intended to increase the lifetime, because it is assumed that the second valve will prevent leakage after the first valve fails. In addition, the silveroxide is expected to have antifungal properties. Speaking pressures and valve opening pressures of the Blom-Singer Dual Valve are reported to be higher than in the Blom-Singer Classic 20 Fr. Blom-Singer Dual Valve prostheses were used with 20 Fr shaft diameter and inserted with the gel cap method. See Fig. b.
