Background: Subcutaneous mastectomy is one of the most common procedure in Female to Male transexualism. The sensitivity of nipple-areola-complex (NAC) postoperatively is still unclear.
Objective: To evaluate nipple-areola-complex (NAC) sensation after female to male subcutaneous mastectomy comparing between semicircular, concentric circular and free nipple graft techniques.
Materials and Methods: The present study included 47 patients who underwent subcutaneous mastectomy (MG) with semicircular (SC, n=6), concentric circular (CC, n=17) and free nipple graft technique (FNG, n=24). NAC sensitivity was assessed for touch, pain, cold temperature, erogenous sensation and nipple erection.
Results: The most sensation patients concerned is touch sensation (58%), pain (18%), erogenous/erection (8%) and cold (7%). For touch sensation SC and CC still had touch sensation but 27% of FNG had loss touch sensation (p=0.001). For pain sensation SC and CC still had touch sensation but FNG had lost pain 33% at areola and 23% at nipple (p<0.001). For cold sensation 12% of CC and 25% of FNG had lost cold sensation at areola (p<0.001) and 12% of CC and 9% of FTG had lost cold sensation at nipple (p<0.001). For erogenous sensation 50% of SC, 35% of CC and 77% of FNG had lost erogenous sensation. For nipple erection 50% of SC, 35% of CC had erect but no nipple erection in FNG.
Conclusion: All sensation parameters of NAC. SC is better than CC and FNG is the worst. The most sensation patients concerned is touch sensation.
