AlloDerm versus dermamatrix in immediate expander-based breast reconstruction: A preliminary comparison of complication profiles and material compliance

Background: Allogenic acellular dermal matrix can be used in single-stage, expander-based immediate and delayed breast reconstructions to provide inferolateral prosthesis coverage and reconstruction of the inframammary fold. Two allogenic dermal matrix products currently available, AlloDerm and DermaMatrix, differ in method of storage, cost, and intraoperative preparation. The purpose of this study was to determine, first, whether there are any significant differences in the rates of postoperative complications, material compliance, or capsule characteristics; and second, if differences are present, whether they had any impact on final outcome. Methods: After institutional review board approval, a retrospective analysis of prospectively collected data of 30 patients (50 breasts) who underwent immediate expander-based breast reconstructions using either AlloDerm (n = 25) or DermaMatrix (n = 25) dermal substitutes was performed. Primary endpoints were (1) incidence of seroma, (2) wound infection, (3) number of days requiring drains, (4) rate of tissue expansion, (5) final expanded volume, (6) final implant volume, and (7) neovascularization. Results: The mean follow-up was 6.7 months. During this time, no significant differences in the complication profile were found between the two groups. Both dermal substitutes were found to be well incorporated, with evidence of neovascularization, on histologic examination. Conclusions: This study demonstrated no significant differences in the rate of complications or material compliance. The total complication rate was 4 percent, with seroma and wound infection being the most common complications. The authors’ preliminary findings indicate no significant difference between implant/expander-based reconstructions using AlloDerm and those using DermaMatrix.

Results of immediate breast reconstruction after skin-sparing mastectomy.

Skin sparing mastectomy (SSM) removes the breast, nipple–areolar complex, previous biopsy incisions, and skin overlying superficial tumors. Preservation of the native skin envelope facilitates immediate breast reconstruction. The procedure has been adopted for the treatment of breast cancer. All cases of SSM and immediate breast reconstruction performed by the senior author (G.W.C.) from January 1, 1993, through December 12, 1997, were reviewed. Patient demographics, cancer staging, treatment, types of surgery performed, and postoperative outcomes were examined. Aesthetic outcomes were measured using four 3-point subscales. A total of 100 patients underwent 118 SSMs during the study period. The American Joint Committee on Cancer staging was as follows: stage 0, 27 patients; stage I, 25 patients; stage II, 39 patients; stage III, 7 patients; stage IV, 3 patients; recurrent, 2 patients; and cystosarcoma phylloides, 1 patient. The mean follow-up was 42.7 months. Local recurrence occurred in 2 patients (2.7%). Reconstructive methods included the transverse rectus abdominis musculocutaneous flap (N = 82; pedicled, 73; free, 9), the latissimus flap (N = 18), and tissue expansion (N = 20). Two patients underwent contralateral delayed reconstruction. The aesthetic results achievable with the three methods were similar. The failure rate was higher for expander reconstruction (10%) than those observed for transverse rectus abdominis musculocutaneous (4.9%) and latissimus (5.6%) flaps. SSM can be used in the treatment of invasive breast cancer without compromising local control. The aesthetic results of the three methods were similar, but tissue expander reconstruction had a higher failure rate.

The management of orbitozygomatic fractures

Orbitozygomatic injuries are among the most common fractures encountered by the plastic surgeon. Appropriate management depends on an accurate diagnosis, focusing on the physical examination and data from computed tomography scans. One must pay particular attention to the orbital component of this injury, as it is from this that so much of the morbidity relating to these fractures is incurred. As with all facial fractures, accurate reduction is paramount to a successful outcome. As many buttresses as are necessary should be visualized to ensure an anatomic reduction. The amount and location of fixation depend on the fracture anatomy.A successful outcome may be expected if these basic principles are followed.

The Limited Scar Mastopexy: Current Concepts and Approaches to Correct Breast Ptosis

The literature on short scar mastopexy was reviewed, with a focus on the different techniques. Currently four techniques have been described: the periareolar, the vertical, the inverted-T, and the L-shaped scar. The different techniques were evaluated with regard to patient selection, operative techniques, scar length, and complications. A large number of techniques have been published for minimal ptosis, whereas for significant ptosis, the number of surgical options is limited. It is evident that limited scar techniques can be applied to all grades of ptosis, but there is no one technique that can satisfactorily correct all degrees of ptosis. Plastic surgeons should weigh the advantages and limitations of each technique to correctly address breast ptosis. This article reviews an algorithmic approach to correct all degrees of ptosis with mastopexy.

Lower Third Nasal Reconstruction: When Is Skin Grafting an Appropriate Option?

Background: A full-thickness skin graft is generally not considered the ideal replacement for the thick, sebaceous skin of the nasal tip, ala, lower sidewalls, or dorsum. Instead, many clinicians prefer to reconstruct these defects with local or axial composite flaps that incorporate skin, subcutaneous tissue, and fat. Methods: The authors conducted a retrospective analysis of 55 consecutive patients who underwent reconstruction of lower third nasal defects with full-thickness skin grafts between 2002 and 2007 performed by the senior author (J.F.T.). All of the patients in this review underwent skin cancer ablation by means of Mohs’ micrographic surgery. Results: Good aesthetic results, based on preoperative and postoperative photographic analysis of contour and pigmentation, have been achieved in both the recipient and donor sites in 52 of 55 patients. Three patients, all of whom were smokers, experienced loss of the skin graft requiring alternative reconstructive techniques. Conclusions: Under certain conditions, skin grafting of defects of the caudal third of the nose offers a viable reconstructive option that yields good contour and color match. Careful analysis of defect size, location, and depth and consideration of donor-site skin thickness and pigmentation are vital for accurate replacement of the thick, pitted, sebaceous skin of the caudal nose. An evolution in technique has revealed that the forehead donor skin often provides a more consistent color and contour match in such reconstructions. Secondary dermabrasion of the graft provides a critical step for obtaining final aesthetic contour and color.

The pyriform ligament.

Background: Several ligaments are believed to support the nasal tip. Intraoperative dissection has suggested that a broader ligament may exist along the pyriform rim than has been previously noted. This observation, along with the concept that pyriform rim shape may affect nasal tip projection by ligamentous fixation, led to the present study. Methods: Ten hemifacial fresh cadaver dissections were performed. Sequential dissection was performed of tissue layers aided by magnification with loupes and an operating microscope. The fascial connection between pyriform rim bone and the upper and lower lateral cartilages and to the alar base was noted. The relationship of upper to lower lateral cartilage, and of the investing fascia to the lower lateral cartilage, was defined. Results: A dense fascial system was noted in all cadaver dissections arising from the periosteum of the pyriform rim. This ligamentous system inserted onto both the upper and lower lateral cartilages. It encompassed the previously described lateral sesamoid complex ligament and the ligament between the upper and lower lateral cartilage. This fascia has a consistent anatomical location and spans the pyriform rim from nasal bone to anterior nasal spine. Conclusions: A ligament exists between the pyriform rim and lateral cartilages and is broader and more expansive than previously described. It encompasses the previously described lateral sesamoid complex and the ligament between the upper and lower lateral cartilages. The consistent anatomical origin of this membrane suggests that the term “pyriform ligament” may be appropriate nomenclature. This ligament may be important in translating anatomical shape—and distortion—of the pyriform rim to the nasal cartilages, and may therefore affect tip shape, tip projection, and nasal vault architecture.

79 billion, or 6 percent of total annual national health care expenditures. Office-based procedures comprise a 10-fold increase in risk for serious injury or death as compared with an ambulatory surgical facility. Methods: This article reviews the literature on office-based patient safety issues. It places special emphasis on the statements and advisories published by the American Society of Plastic Surgeons’ convened Task Force on Patient Safety in Office-Based Settings. This article stresses areas of increased patient safety concern, such as deep vein thrombosis prophylaxis and liposuction surgery. Results: The article divides patient safety in health care delivery into three broad categories. First, patient safety starts with emphasis at the administrative level. The physician or independent governing body must develop a system of quality assessment that functions to minimize preventable errors and report outcomes and errors. Second, the clinical aspects of patient safety require that the physician evaluate whether the procedure(s) and the patient are proper for the office setting. Finally, this article gives special attention to liposuction, the most frequently performed office-based plastic surgery procedure. Conclusions: Patient safety must be every physician’s highest priority, as reflected in the Hippocratic Oath: primum non nocere (“first, do no harm”). In the office setting, this priority requires both administrative and clinical emphasis. The physician who gives the healing touch of quality care must always have patient safety as the foremost priority.

Nasal reconstruction: an overview and nuances.

Breast conservation has been associated with poor cosmetic outcome when used to treat breast cancer in patients who have undergone prior augmentation mammaplasty. Radiation therapy of the augmented breast can increase breast fibrosis and capsular contraction. Skin‐sparing mastectomy and immediate reconstruction are examined as an alternative treatment. Six patients with prior breast augmentation were treated for breast cancer by skin‐sparing mastectomy and immediate reconstruction. One patient underwent a contralateral prophylactic skin‐sparing mastectomy. Silicone gel implants had been placed in the submuscular location in five patients and in the subglandular position in one patient a mean of 10.2 years (range, 6 to 20 years) before breast cancer diagnosis. The mean patient age was 41.3 years (range, 33 to 56 years). Four independent judges reviewed postoperative photographs to grade the aesthetic results in comparison with the opposite native or reconstructed breast. The American Joint Committee on Cancer staging was stage 0 in one patient, stage I for four patients, and stage II for one patient. Five of the six patients presented with a palpable breast mass. Latissimus dorsi flap reconstruction was performed in four patients (bilaterally in one) and a transverse rectus abdominis muscle (TRAM) flap was used in two patients. Three patients were treated by skin‐sparing mastectomy with preservation of the breast implant (two patients with latissimus flaps, and one patient with a TRAM flap). The tumor location necessitated the removal of implants in two patients (one patient with a latissimus flap and one with a TRAM. A saline implant was placed under the latissimus flap after gel implant removal. The patient who underwent bilateral skin‐sparing mastectomies desired explantation and placement of saline implants. No remedial surgery was performed on the opposite breast to achieve symmetry. Complications occurred in two patients at the latissimus dorsi donor site (seroma in one patient, and seroma and infection in one). Five patients underwent complete nipple reconstructions. The mean duration of follow‐up was 33.6 months (range, 15.5 to 70.3 months), and there were no recurrences of breast cancer. The aesthetic results were judged to be good to excellent in all cases. Skin‐sparing mastectomy and immediate reconstruction can be used in patients with prior breast augmentation, with good to excellent cosmetic results. Depending on the tumor and implant location, the implant may be preserved without compromising local control. (Plast. Reconstr. Surg. 107: 687, 2001.)
