An overview of permanent and semipermanent fillers

Summary: The demand for safe, effective, long-lasting, biocompatible dermal filler materials is increasing. Many products that include synthetic polymers and autologous tissue have emerged that attempt to meet these criteria. An overview of injectable permanent fillers, including ArteFill, Aquamid, and silicone, and semipermanent fillers, including Radiesse, Sculptra, and autologous fat, is presented. A discussion of their composition, histologic characteristics, antigenicity, U.S. Food and Drug Administration approval status, indications for use, efficacy, injection technique, and adverse effects is provided.

Nonsyndromic craniosynostosis: current treatment options.

The significance and etiology of abnormal skull shape have been under investigation since ancient times. Nonsyndromic, or isolated, craniosynostosis predominates and is defined as suture fusion that creates functional impairments related to local effects of the fusion. The purpose of this article is to present our current approach to patients with nonsyndromic craniosynostosis, outlining the place of both open, conventional approaches and newer, minimally invasive, endoscopic assisted craniosynostosis correction.

Clinical experience with a new fast-resorbing polymer for bone stabilization in craniofacial surgery.

Polylactic acid (PLA) and polyglycolic acid have been successfully used as suture material during the past 30 years and have been successfully used in various orthopedic and craniofacial applications, with increasing frequency during the past 15 years. 1-5 To eliminate some of the problems seen with the longer-lasting Macropore PLA product and other longer-lasting resorbable systems, a new fast-resorbing polymer (FRP) was manufactured by Macropore-Medtronic Neurologic Technologies, Inc. from commercially available 85:15 poly(D,L-lactide-co-glycolide) raw material using traditional melt-processing techniques. The delivery system is easily used and uses essentially the same instrumentation. One hundred and sixty eight patients who had implantation of the FRP were studied. Detailed clinical evaluation was completed after surgery and at each postoperative visit. Overall, there was a 2.1% implant-related complication rate, which compared favorably to the 8.5% implant-related complication rate associated with the longer-lasting PLA product. All patients who received FRP implants have had maintenance of stable bony fixation, followed by bony healing and satisfactory or excellent cosmetic results. The results from the FRP study indicate that the FRP material and implants are safe and effective in craniomaxillofacial applications.

ArteFill: a permanent skin filler.

The ideal soft-tissue filler for wrinkles and skin defects should be safe, biocompatible, resistant to phagocytosis, persist and maintain its volume without being resorbed or degraded. ArteFill®, an improved, next-generation derivative of Artecoll®, is expected to become the first and only FDA-approved permanent filler for use in the USA in 2006 and will be available worldwide. ArteFill consists of polymethylmethacrylate microspheres suspended in a 3.5% solution of bovine collagen containing 0.3% lidocaine. In this article, the pathophysiology, efficacy and safety of ArteFill are discussed and details of its injection technique are provided. Insight into the pharmacoeconomic value of ArteFill over nonpermanent fillers and ArteFill’s unique role in the growing world market of dermal fillers is provided.

Comparison of open versus minimally invasive craniosynostosis procedures from the perspective of the parent

Craniosynostosis, or the premature closure of the sutures of the skull, has historically been repaired in an open manner and included extensive cranial reconstruction. In recent years, technological advancements have given surgeons the ability to perform repairs with minimal surgical invasion. With the advent of endoscopy and bioresorbable plates, recent reports [J Craniofac Surg 2002;13(4):578-82] have emphasized attempts at decreased morbidity. Recently, researchers have been able to compare the results of traditional open and minimally invasive techniques in 45 craniosynostosis cases, demonstrating decreased operating room time, blood loss, transfusions, complications, and hospital stay in minimally invasive patients [Clin Plast Surg 2004;31(3):429-42]. Many of the parameters comparing the 2 types of procedures are easily quantified and comparable, but a variety of other considerations, such as the parents reaction to the stress of surgery, arise. The purpose of this study was to compare the effects of these surgical procedures on the parents level of stress at the time of operation. To accomplish this, we measured stress postoperatively using the Parenting Stress Index-Short Form. Subjects undergoing surgical treatment of craniosynostosis were placed into 2 groups: open versus minimally invasive. To test for confounding factors, subjects were subcategorized for sex, parents sex, ethnicity, and parents marital status. Analysis of our data reveals a statistically significant decrease in total stress in the households of minimally invasive patients.

Lateral gastrocnemius myocutaneous flap transposition to the midlateral femur: extending the arc of rotation.

AbstractWe report the successful use of an extended lateral gastrocnemius myocutaneous flap for coverage of the midlateral femur using successive delayed elevations. A 62-year-old man underwent wide resection of a liposarcoma of the right anterior thigh with free flap reconstruction and subsequent radiation therapy 10 years before. Four years later, the patient fractured his irradiated femur and was treated with a retrograde intramedullary nail, which subsequently became infected, causing osteomyelitis of the distal femur, septic arthritis of the knee joint, and nonunion of his pathologic fracture. Although advised by numerous surgeons to undergo above-knee amputation, we offered our motivated patient a multidisciplinary approach to clear his infection and pathology; implanted new orthopedic hardware; performed delayed flap reconstruction; and rehabilitated him back to painless, unassisted ambulation. The extended lateral gastrocnemius myocutaneous flap used provided perfused soft tissues and durable coverage for the patient’s exposed orthopedic hardware of the midlateral femur, 14 cm above the joint line of the knee. By using this flap to cover a femur defect well above published heights, our patient avoided amputation after years of worsening incapacitation.

Negative Pressure Wound Therapy with Instillation in a Chronic Non-Healing Right Hip Trochanteric Pressure Ulcer.

Complex pressure ulcer wound sites often present with a wide scope of barriers to healing ranging from high colonization of multi-drug-resistant pathogens to tortuous internal anatomy which make the wound recalcitrant to traditional wound care including standard negative pressure wound therapy (NPWT). Negative pressure wound therapy with instillation (NPWTi-d) provides an opportunity to manage and heal wounds with indications not met by standard NPWT such as cavitating wounds with complex undermining and tunneling. In this clinical case report, a patient who presented with a chronic, non-healing Stage IV pressure ulcer underwent a tensor fascia lata flap reconstruction that was complicated by a partial flap-tip nonadherence with associated partial dehiscence of the flap incision that proved unresolvable until application of adjunctive NPWTi-d which allowed the wound to experience a robust rate of granulation, contraction, and closure.

Flap Sandwich: Use of a De-Epithelialized TRAM Flap, Partial Latissimus Dorsi Flap and Dermal Patch to Reconstruct Coccidioidomycosis-Induced Bronchopleural Fistula

Problem: A healthy 38 year old gentleman developed cough and cachexia, later found to be Coccidiodes pneumonia. He successively developed a recurring pneumothorax and chronic empyema recalcitrant to antimicrobial therapy, with eventual progression into a chronic bronchopleural fistula. After multiple failed surgeries including pleural stripping and over a year of chest tube dependence and progressive shortness of breath, he considered either an Eloesser flap for controlled permanent drainage, or even a pneumonectomy. His unique surgical problems also included limitations of workhorse flaps needed to reach his defects. He was left with a shortened latissimus muscle flap and no serratus flap (both from prior thoracotomy and scarring). With his significant respiratory compromise and deep wounds beyond the reach of rectus abdominus or pectoral flaps, we were left with limited access to these deep structures beyond the reach of standard chest flaps. With modifications in access, materials, and techniques, we were able to adapt to obtain success.
