Background: Traditionally, the columella can be difficult to reconstruct because of its unique contours, paucity of adjacent soft tissues, and tenuous vascularity. When local or regional tissues are unavailable, microsurgical transfer can provide a means for reconstruction. In this retrospective review, the authors report their experience with microsurgical reconstruction of the columella.

We previously described successful use of the first dorsal metacarpal artery free flap for salvage of a subtotal nasal reconstruction. In this retrospective study, we have expanded our experience to 7 consecutive cases in which a FDMFF was utilized to salvage a nasal reconstruction.

Subtotal loss of the nose is a devastating occurrence. Traditional approaches to reconstruction have employed techniques that sequentially restore the nasal lining, support and external cover using autologous tissues. The results can be quite variable and are heavily weighted on surgical experience and expertise.

Methods: An email survey of American Society for Reconstructive Microsurgery (ASRM) and World Society for Reconstructive Microsurgery (WSRM) members regarding their experiences with postoperative arterial vasospasm was conducted, returning 116 responses.
The science and technical acumen in the field of vascularized composite allotransplantation has progressed rapidly over the past 15 years, and transplantation of specialized units of the face, such as the nose, appears possible. No study to date has evaluated the technical feasibility of isolated nasal unit transplantation (NUT). In this study, we explore the anatomy and technical specifics of NUT.

However, undiagnosed thrombophilias have been associated with microsurgery free flap failures. We present a case of successful free tissue transfer in a patient with lupus anticoagulant and review the literature.

The color can be improved by removing the epidermis and overgrafting with a thin, split-thickness skin graft of scalp epidermis. This report reviews the authors' clinical experience using this technique.

The authors review the literature to estimate several clinical parameters pertaining to barbed thread suspensions.
Methods: The authors performed a MEDLINE search using the keywords "barbed and suture," "thread and suspension," "Aptos," "Featherlift," and "Contour Thread.
Background: Facial reconstruction with only free microvascular flaps has rarely produced an aesthetic result. Menick stated, "Distant skin always appears as a mismatched patch within residual normal facial skin." In addition, earlier techniques using a single large nasal lining flap or bilateral nasal lining vaults incurred a high incidence of airway obstruction.

Background: In large-breasted women, those with midline abdominal scars, or those with scant abdominal tissue, a unipedicled lower abdominal flap may be insufficient for breast reconstruction. In these circumstances, bipedicled flaps may best satisfy the reconstructive requirements, but outcomes with bilateral free flaps for unilateral breast reconstruction are generally lacking.
Methods: A retrospective review of patients in whom two vascular pedicles/flaps were used to simultaneously reconstruct a single breast was used to assess operative outcomes.
As breast reconstruction has an aesthetic endpoint, secondary surgical intervention is an integral part of this process. This article examines revision in autologous breast reconstruction from the perspective of clinical priority. The authors examine challenges they may be faced in autologous breast reconstructions and suggest surgical approaches toward their resolution.

When compared to the transverse rectus abdominis myocutaneous (TRAM) flap, the muscle-sparing deep inferior epigastric perforator (DIEP) flap and the superficial inferior epigastric artery (SIEA) flap are common options that minimize donor-site morbidity. For patients with inadequate flap perfusion via either system, alternative surgical options that permit preservation of the abdominal musculature are limited.

Methods: A retrospective review was performed of 11 consecutive patients presenting for reconstruction of the nasal lining alone during the period from October of 1996 through March of 2003.
Development of a wound infection after nasal reconstruction can place the entire reconstructive effort in jeopardy. The approach to management in these cases has traditionally entailed wound drainage, removal of involved graft material, and debridement of nonvital tissue. Following adequate wound healing, delayed reconstruction is then performed, with the final result often compromised in form and function.

In a pilot study using an experimental rat model, we induced liponeogenesis with a combination of Matrigel and basic fibroblast growth factor in an fibrovascular scaffold, isolating the construct to a pedicled blood supply (the superficial inferior epigastric vessels) via a silicone housing, creating an engineered three-dimensional adipose tissue construct. Adipose tissue and vascular ingrowth were assessed histologically and followed by serial study at 4-week intervals for 16 weeks.
View Article and Find Full Text PDFAlthough the field of tissue engineering has been the focus of a great deal of promise and study, only recently has significant attention been given to the engineering of soft tissues. The applicability of an engineered adipose construct as a basic science model and a reconstructive tool is unquestioned; yet, there have been limitations in previous work, specifically issues of construct size and maintenance over time. This article briefly overviews the pivotal factors necessary for adipocyte growth and differentiation, optimal scaffolds for the engineering of soft tissues, and a means of providing vascular support for these highly demanding cells.
