Bilateral scrotal flap: pedicle and dimension of flap in cadaveric dissections.
Penile paraffinoma is not uncommon among Thai males. The definite treatment involves the complete removal of skin and subcutaneous tissue infiltrated by the foreign material and resurfacing in the penile shaft with skin graft or scrotal flap in severe cases. In the present study the authors undertook an anatomical investigation of external pudendal vessels and scrotal skin in 5 soft cadavers. The authors found that the anterior scrotal artery branching from the external pudendal artery at the point 2-2.7 cms. from midline at pubic symphysis level and running in the internal spermatic plane. Anterior scrotal artery supplied scrotal skin 62.5-100% (mean 75.9%) in anteroposterior dimension and 66-100% (mean 88%) in superoinferior dimension. The authors recommended that this flap must elevate deep to the internal spermatic plane, just close to tunica vaginalis and the dimension of flap should not be more than 62.5% in anteroposterior and 66% in superoinferior dimension.
