Abstract

OBJECTIVE

To illustrate problems observed with low-porosity expanded polytetrafluoroethylene soft tissue implants and to describe a new dual-porosity implant, the technique for insertion, and this author's preliminary experience.

METHOD

A review of 175 pieces of SoftForm (Collagen Corporation, Palo Alto, Calif) placed in 69 patients over 3 years was performed. Between October 1, 1997, and September 30, 2000, 106 Advanta implants (Atrium Medical Corporation, Hudson, NH) in 42 patients have been carried out. A new instrument for implant insertion and the procedure used is described herein.

RESULTS

The low-porosity expanded polytetrafluoroethylene implants demonstrated a significant amount of problems with shrinkage and migration.

CONCLUSIONS

Preliminarily, the dual-porosity implants would appear to offer a lower incidence of these complications. They are subjectively softer to feel once in place. Insertion is quick and easy using the method described herein.

摘要

目的

阐述低孔隙率膨体聚四氟乙烯软组织植入物所观察到的问题，并描述一种新型双孔隙率植入物、植入技术以及作者的初步经验。

方法

对3年期间69例患者植入的175块SoftForm（胶原蛋白公司，加利福尼亚州帕洛阿尔托）进行回顾性研究。在1997年10月1日至2000年9月30日期间，对42例患者植入了106块Advanta植入物（阿特里姆医疗公司，新罕布什尔州哈德逊）。本文描述了一种用于植入物植入的新器械及所采用的手术方法。
