Abstrakt: Introduction: Autologous breast reconstruction (ABR) uses a harvested tissue flap from the abdomen, posterior thigh, or buttocks to rebuild the breast postmastectomy. Identification of nerves for use in autologous sensate breast reconstruction flaps is an important surgical consideration as loss of breast sensation is a common risk of ABR. The posterior femoral cutaneous nerve (PFCN) and its branches supply sensory innervation to skin of the posterior thigh, leg, perineum, and buttocks, creating a feasible candidate for sensate profunda artery perforator (PAP) flaps for reestablishing breast sensation through ABR. This study characterized PFCN perforating branches located within the PAP flap region as compared to an anatomical landmark intersection (ALI). Twenty-three posterior thigh regions from 15 formalin-embalmed donors were dissected to the level of deep fascia to identify PFCN branches. PFCN branch diameter (mean, 1.34 ± 0.35 mm) and length (mean, 8.82 ± 5.78 mm) piercing the deep fascia were measured; branches were retro-dissected proximally to the PFCN trunk and the distance recorded (mean, 92.55 ± 38.00 mm). The distance to branch emergence from ALI (mean, 113.55 ± 19.80 mm) and from the midline of the posterior thigh (mean, 18.90 ± 11.17 mm) were calculated. Two-Tailed T-tests comparing the left and right limb of 7 donors determined bilateral, statistically significant difference between the length of branch emergence back to the main trunk of PFCN (P = .00). These findings illustrate the presence of adequate yet variable PFCN branches within the PAP flap region in regards to diameter, length, and location for use in sensate ABR.
