Refinements in the Preexpanded Distant Flap for Giant Melanocytic Nevi of the Upper Extremity in Pediatric Patients

Refinements in the Preexpanded Distant Flap for Giant Melanocytic Nevi of the Upper Extremity in... Background: Surgical treatment of large and giant congenital melanocytic nevi (GCMN) of the upper extremity is challenging because of limited options for reconstruction. A preexpanded distant flap is considered an important option in upper extremity reconstruction, where the soft tissue available for use is limited. The authors aimed to refine the preexpanded distant flap after excision of the GCMN in the upper extremity. Methods: Large (>10 cm) and giant (>20 cm) congenital melanocytic nevi of the upper extremities treated with tissue expansion and distant flaps over 10 years were retrospectively reviewed, and the authors describe in detail the surgical strategies for reconstruction of the upper extremity with a distant flap. Results: From March of 2010 to February of 2020, 13 patients (mean age, 2.87 years) treated with 17 preextended distant flaps were included. The mean flap dimension was 154.87 cm2, ranging from 15 × 5 to 26.5 × 11 cm. All procedures were successfully completed except for one, in which partial flap necrosis occurred. Preconditioning was performed before flap transfer in 5 patients with larger rotation arcs and flap dimensions. The mean duration of postoperative follow-up was 51.85 months. A new reconstructive protocol was proposed that combined the 3 elements, including a distant flap, tissue expander, and preconditioning. Conclusions: In the treatment of GCMN in the upper extremities, careful planning and multiple stages are required. For pediatric patients, the preextended distant flap with preconditioning is useful and effective for reconstruction.

Abstract

Background: Surgical treatment of large and giant congenital melanocytic nevi (GCMN) of the upper extremity is challenging because of limited options for reconstruction. A preexpanded distant flap is considered an important option in upper extremity reconstruction, where the soft tissue available for use is limited. The authors aimed to refine the preexpanded distant flap after excision of the GCMN in the upper extremity. Methods: Large (>10 cm) and giant (>20 cm) congenital melanocytic nevi of the upper extremities treated with tissue expansion and distant flaps over 10 years were retrospectively reviewed, and the authors describe in detail the surgical strategies for reconstruction of the upper extremity with a distant flap. Results: From March of 2010 to February of 2020, 13 patients (mean age, 2.87 years) treated with 17 preextended distant flaps were included. The mean flap dimension was 154.87 cm2, ranging from 15 × 5 to 26.5 × 11 cm. All procedures were successfully completed except for one, in which partial flap necrosis occurred. Preconditioning was performed before flap transfer in 5 patients with larger rotation arcs and flap dimensions. The mean duration of postoperative follow-up was 51.85 months. A new reconstructive protocol was proposed that combined the 3 elements, including a distant flap, tissue expander, and preconditioning. Conclusions: In the treatment of GCMN in the upper extremities, careful planning and multiple stages are required. For pediatric patients, the preextended distant flap with preconditioning is useful and effective for reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
