Background and Objectives : Expanded polytetrafluoroethylene (ePTFE) is an alloplasticimplant widely used in augmentation rhinoplasty. However, ePTFE implant is known to be vulnerableto postoperative infection and inflammation. We aimed to verify the safety of the materialby analyzing the results of augmentation rhinoplasty using ePTFE carried out in a single institutionfor 10 years.
Subjects and Method : From April 2009 to June 2018, 238 patients who underwent augmentationrhinoplasty with ePTFE were included in the study. There were 187 male patients and 51female patients. Patients’ medical records, preoperative and postoperative photographs wereanalyzed, and postoperative implant migration, inflammation, and infection were investigated.
Results : Of the 238 patients, 10 underwent revision surgery, and 87 (36.6%) underwent concomitantosteotomy for the correction of the deviated nose. Of the 5 patients (2.1%) who showedpostoperative implant migration, 4 patients belonged to the osteotomy patients group while 1patient belonged to the no-osteotomy group. There was more frequent implant migration inpatients who underwent osteotomy; however, there was no statistically significant difference(p=0.06). In all of the five patients, the degree of implant migration was minimal, therefore nopatient required revision surgery. No inflammatory reaction or infection was found after surgery.
Conclusion : ePTFE is a safe material for augmentation rhinoplasty and is not susceptible toinfection after surgery if used through appropriate surgical procedures.
