Nylon suture has frequently been used from the viewpoint of scar quality. Polydioxanone suture is capable of retaining tensile strength longer than the previous absorbable suture that was developed. If the absorbable and nonabsorbable sutures are equivalent with regard to scar stretching, the absorbable suture may be more effective depending on the purpose for which it is used.
The aim is to compare resultant scars and complications arising after wound closure with polydioxanone or nylon.
Nylon and polydioxanone sutures were used for closure of dissected transverse axial rectus abdominis muscle flaps on eight patients, and the resultant scars on the opposite halves of the same wound were compared. Specimens excised were histologically analyzed.
The nylon-sutured and the polydioxanone-sutured scars were similar after surgery. In one patient, suture abscess developed on the nylon side.
For sutures at weight-bearing or thin-skin regions, the absorbable suture for long-term courses may be more conducive to avoiding exposure of the suture.
