| Popis: | Background:. Divided nevus is a rare form of congenital nevus that usually occurs on both upper and lower eyelids of one eye, forming one large nevus when the eyelids are closed. Typically, congenital melanocytic nevi of the body are classified according to their size (small < 1.5 cm, medium 1.5–20 cm, and large > 20 cm). However, because divided nevus of the eyelids is usually relatively small, this classification may be too coarse and not adequate. Furthermore, there is no practical classification for divided nevus of eyelids yet. Methods:. We treated 3 cases of medium and large congenital divided nevus of the eyelids using local flaps based on the idea of esthetic subunits. Also, we proposed a new classification especially for congenital divided nevus of the eyelids based on the idea of esthetic subunits. Results:. All patients were treated successfully with the reconstructive idea of esthetic subunits for the eyelids. Case 1 (medium size) was reconstructed by orbicularis musculocutaneous flap and case 2 (large size) was reconstructed by expanded flap, and case 3 (medium size) was treated by modified V-Y orbicularis oculi musculocutaneous flap. In all cases, the flap color and texture were well matched and satisfactory results were obtained. Also, by using the new classification, we were able to plan practical scheme for divided nevus reconstruction. Conclusions:. The use of our proposed classification and esthetic subunits for the divided nevus of the eyelids allows systematic surgical planning, leading to improved reconstructive outcomes. |
