Summary

The circular defect with dog-ear deformities excision (CDDE) technique offers superior facial lesion removal compared to the 3:1 fusiform excision, resulting in smaller incisions and less wound widening.

Area of Science:

  • Dermatologic Surgery
  • Plastic Surgery
  • Wound Healing

Background:

  • Facial lesion excision requires techniques that optimize wound closure and minimize scarring.
  • Traditional fusiform excision can lead to significant tissue manipulation and longer final incision lengths.
  • The circular defect with dog-ear deformities excision (CDDE) technique is a potential alternative for managing circular defects.

Purpose of the Study:

  • To compare the efficacy of the CDDE technique versus the 3:1 fusiform excision technique for facial lesion removal.
  • To evaluate which technique provides superior wound closure in terms of final incision length and wound characteristics.

Main Methods:

  • Identical 1-cm and 2-cm circular skin defects were created on fresh cadavers.
  • The CDDE technique and the 3:1 fusiform excision technique were applied to contralateral defects.

  • Measurements included circumferential incision length, wound widening, and final incision length; a paired t-test was used for analysis.

    • Main Results:

    • The CDDE technique demonstrated statistically significant reductions in circumference, wound widening, and final incision length for both defect sizes (P < .01).
    • The final incision length to defect ratio was approximately 2.5:1 with CDDE, compared to 3.5:1 with fusiform excision.

    Conclusions:

    • The CDDE excision technique is superior to the 3:1 fusiform excision technique for facial lesion removal.
    • CDDE minimizes tissue excision, reduces wound widening, and results in shorter final incision lengths, indicating improved wound closure.
