Treatment of vesicoureteric reflux by endoscopic injection of Teflon. 1984.

Thirteen girls with grade III-V vesicoureteric reflux were treated by endoscopic injection of Teflon paste behind the intravesical ureter. Fourteen of the 18 treated ureters showed complete absence of reflux after one injection of Teflon. Three ureters required a second injection of Teflon for successful treatment of the reflux. One ureter with grade IV reflux was converted to grade II reflux. Properly carried out, this procedure corrects reflux. It takes less than 15 minutes, may be done as a day procedure, and avoids open surgery. There have been no complications. (Reprinted with permission from Br Med J, 289: 7-9, 1984)

Softform for facial rejuvenation: historical review, operative techniques, and recent advances.

The deep nasolabial fold and other facial furrows and wrinkles have challenged the facial plastic surgeon. A variety of techniques have been used in the past to correct these troublesome defects. Advances in the last five years in new materials and design have created a subcutaneous implant that has excellent properties. This article reviews the development and use of Softform facial implant.

Biomaterials in ossiculoplasty and history of development of prostheses for ossiculoplasty.

From 1956 to the present has been a period of surgical expansion into the middle ear for correction of deafness. This article follows the evolution of microscopic implants designed to replace all or part of the ossicular chain, and the use of biocompatible materials of plastic, metal, and ceramics to form prosthetic devices.

History of Teflon.

The main physical features of Teflon, a plastic fluorated material, are discussed. Since the 2nd World War, its uses have become numerous.

Medical history of Teflon.

The different stages in the medical use of Teflon are recalled. After animal experimentation which started in 1949, Teflon has been used in humans since 1962 in otorhinolaryngology, since 1973 in urology and, more recently, since 1984 in the treatment of vesicorenal reflux. The long-term future is still uncertain, especially with regard to children, for whom life expectancy is long.
