ABSTRACT
Objective@#To investigate the clinical effect of reconstruction of sensory anterolateral thigh perforator flaps in repairing soft tissue defects after radical operation for Paget disease of perineum.@*Methods@#From April 2017 to July 2017, Ningbo First Hospital treated 3 male patients with Paget′s disease of perineum, 2 patients with RayA2 stage and 1 patient with RayB stage. The range of soft tissue defect after resection of tumors is 8 cm×10 cm to 10 cm×12 cm. The anterolateral thigh perforator flaps were designed to repair skin defect, and the lateral thigh cutaneous nerve branch was contained to reconstruct protective sensation and restore autonomic nerve function. Tension-free direct suture was performed in part of the donor site, of which 3 cases were difficult to suture directly, 2 cases were treated with skin grafting and 1 case was closed with skin distractor.@*Results@#All 3 flaps survived. The average area of the flaps was about 12 cm×14 cm. The average follow-up period was 3 months. The appearance and function of the flaps were satisfactory. The average sensory recovery of the flaps was as high as S3. The autonomic nervous function was partially restored. Some of the skin had sweating function and normal skin temperature. At the same time, there was no difference between the urination function and sexual competence before operation. The donor site wound healed well and its appearance and function recovered well.@*Conclusions@#The reconstruction of sensory anterolateral thigh perforator flaps is an good method for repairing soft tissue defect after radical resection of Paget disease of perineum. It has satisfactory results in the protection and reconstruction of donor and recipient areas.
