Horizontal square buried sutures in a two-layered fashion enable direct primary closure for small circular wounds without dog-ears on the face.
BACKGROUND
Dog-ears often lead to lengthening of an excision, and it is desirable to avoid them.


OBJECTIVE
Facial skin, including the subepidermal connective tissue, is flexible and can be used advantageously to minimize dog-ears using a novel buried suture technique.


METHODS
After removing a round lesion, the first horizontal square buried suture (HSBS) was deeply placed parallel to the longitudinal direction of the defect beneath superficial fascia. After the first HSBS was tied, the defect became fusiform but was still largely open. The second HSBS was also placed parallel to the longitudinal direction of the defect but in more superficial fascia and using smaller horizontal buried loops than those of the first deep suture. After the second HSBS in the middle of the dermis was tied, the wound was almost closed without dog-ears. Consequently, few skin sutures were required to finish the operation.


CONCLUSIONS
Using this technique, a small circular or oval defect on the face up to 1 cm in diameter can be closed without any additional excision of the skin and without creating dog-ears.
