Biwinged excision for closure of rounded defect.

B Hirshowitz, T Kaufman, I Amir

Annals of Plastic Surgery

|November 1, 1980

Summary

A novel biwinged surgical technique offers a new method for closing rounded skin defects. This step-closure procedure excises triangular tissue flaps for improved cosmetic results, especially along natural facial lines.

Area of Science:

Plastic Surgery
Dermatologic Surgery
Surgical Techniques

Background:

Closure of rounded defects presents a reconstructive challenge.
Existing methods may result in suboptimal cosmetic outcomes.
Need for versatile techniques applicable to various anatomical locations.

Purpose of the Study:

To introduce and describe a new surgical technique for closing rounded defects.
To evaluate the applicability of the biwinged procedure for cosmetic closure.
To mathematically compare tissue excision with other closure methods.

Main Methods:

Description of the biwinged procedure involving excision of two equal triangles.
Application of the technique to parallel natural wrinkles or contour lines.
Mathematical comparison of healthy tissue excised in biwinged vs. six other procedures.

Main Results:

The biwinged procedure offers a novel approach to defect closure.
The technique allows for closure in a step-like fashion.
Mathematical analysis quantifies tissue excision compared to alternative methods.

Conclusions:

The biwinged procedure is a new technique for closing rounded defects.
Its design allows for camouflage along natural skin lines.
Further evaluation may establish its efficacy in plastic and reconstructive surgery.
