Abstract

Background

Two general methods of otoplasty exist: cartilage sparing and cartilage cutting. The Mustardé and Furnas techniques use suture to modify cartilage layout.

Purpose

To describe the suture materials used in surgical correction of ear deformities. To analyze the extrusion rate of suture materials in otoplasty procedures performed at our institution. To compare the suture materials used.

Study Design

Descriptive, retrospective, observational study on 343 ears undergoing otoplasty between 1996 and 2016 using the combined Mustardé-Furnas technique.

Subjects and Methods

We divided patients into three groups, depending on the suture material used. These were polypropylene (Prolene®), nylon polymer (Ethilon®) and polytetrafluorethylene (Goretex®). All patients were evaluate 12 months post procedure, for the presence or absence of extrusion.

Results

5/30 (17%) ears sutured with Prolene® and 30/163 (18%) ears sutured with Ethilon® were found to have presence of extrusion during follow-up. However, only 5/150 (3%) ears sutured with Goretex® were observed to have extrusion. There was a statistically significant difference between Goretex® and Prolene® (p=0.013) and between Goretex® and Ethilon® (p<0.001). However, no difference was observed between Prolene® and Ethilon®.

Conclusion

The lowest extrusion rate among our patients was with Goretex® suture.
