Introduction: Lipofilling has become a widely used procedure in breast reconstruction after mastectomy or breast-conserving treatment. The possibility that this technique may increase stimulation of cancer development between the potential tumor bed and the lipoaspirates grafts has been raised regarding its safety. The aim of this study was to identify the oncological risks associated with this procedure in our institution.

Nasal columella defects can result in significant cosmetic and functional deformities. If a local flap transfer cannot be performed, columella reconstruction becomes a significant challenge for the surgeon. The columella of a healthy 30-year-old woman whose nose was scarred and contracted because of cocaine abuse, was successfully reconstructed by transferring a microvascular free flap from the first web space of the foot.

Purpose: Many investigators have studied the vascular anatomy of the dorsal metacarpal arteries but little attention has been paid to the exact distribution of the cutaneous perforators of the dorsum of the hand. We present an anatomic study of the cutaneous perforators within the fourth dorsal interosseous space, which was supposed to have the most inconsistent vascular anatomy.

Methods: Twenty hands were dissected after black latex injection.

Purpose: To study the vascularization of the fourth dorsal intermetacarpal space and to determine the contribution of the dorsal metacarpal artery and the interosseous muscle fascia to flap viability. The fourth dorsal intermetacarpal space is considered to be less reliable as a donor site because of previously reported vascular variations.

Methods: We performed 15 cadaver dissections.

Background: Many augmentation mammaplasty techniques have been developed paying special attention to incision location and pocket plane to achieve more natural-looking breasts.

Methods: The authors' technique of choice in patients with mammary hypoplasia, empty breasts following a diet program, or more than one lactation episode causing skin flaccidity without ptosis is the placement of an anatomical implant using a transaxillary approach in a subfascial plane with endoscopic assistance. Thus, ideal patients are those presenting mammary hypoplasia, empty breasts following two or more lactation episodes, and breast skin flaccidity without ptosis, with the nipple-areola complex placed above the inframammary fold.
