Analysis of the Complication of Expanded-Polytetrafluoroethylene(e-PTFE) as Augmentation Material in Oriental / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Although the complication of using e-PTFE as augmentation material in rhinoplasty for occidental patients have been reported, but only a little information is available for oriental patients. The aim of the present study is to analyze complications of e-PTFE for nasal augmentation in rhinoplasty for oriental patients. MATERIALS AND METHOD: The subjects consisted of 1376 patients who had been performed augmentation rhinoplasty with e-PTFE between January 1994 and October 2002. The subjects were classified according to experience of rhinoplasty. The first group included primary cases and second group revision cases. The revision group was divided into two groups according to the different techniques performed, one being the minor group that had been performed the simple technique, and the other group that had been performed the complicated technique. We reviewed postoperative complications of augmentation rhinoplasty with artificial implants including displacement, surface irregularity, infection, dorsal line and height problem, soft tissue reaction, extrusion and resorption. RESULTS: Side effects occurred in 127 (9.2%) of the 1376 patients: 38 (29.9%) was displacement, 29 (22.8%) dorsal height problem, 23 (18.1%) surface irregularity, 18 (14.2%) dorsal line and 18 (14.2%) infection and others. CONCLUSION: Compared with other autogenous and artificial materials, the study found e-PTFE as a good material for augmentation rhinoplasty for the orientals.
