Microbial growth within saline-filled tissue expanders.

BACKGROUND: Tissue expander based reconstruction is the most common restorative procedure used following mastectomy. Infection is a common complication in the post-operative period and may lead to failure of the reconstruction. Various previous studies have investigated the potential sources of infection during these procedures. The purpose of this study was to examine the fluid within the saline-filled tissue expander at time of implant exchange for the presence of microbial growth. METHODS: Twenty-five patients (39 breasts) were enrolled in the study. Fluid samples were sent for Gram stain, aerobic, anaerobic, fungal, and acid-fast bacilli (AFB) cultures. Average age was 53.1. Mean time to exchange was 7.7 months. Average follow-up was 25 months. RESULTS: None of the samples were positive for microbial growth at final culture (0/39). DISCUSSION: These results show the tissue expander fluid maintains a microbial-free environment during the expansion process, and is unlikely a significant source of contamination in cases of infection. LEVEL OF EVIDENCE: Level II, prospective cohort, therapeutic study.

Porous polyurethaneurea (Artelon) joint spacer compared to trapezium resection and ligament reconstruction.

PURPOSE: To examine outcomes and complications of the porous polyurethaneurea (Artelon; Small Bone Innovations, Morrisville, PA) spacer compared to traditional surgical treatment of trapeziectomy with ligament reconstruction and tendon interposition (LRTI). METHODS: A retrospective chart review was undertaken of patients with carpometacarpal (CMC) arthritis who had either placement of an Artelon spacer or LRTI. Patients were brought back to clinic for interview and functional testing. Pain was graded using a visual analog scale. Grip and pinch strength, as well as range of motion at the first CMC joint, were measured. Nine-hole peg, Moberg pickup, and Jebson-Taylor tests were performed. Research and Development 36, Michigan Hand Outcomes, and Quick Disabilities of the Arm, Shoulder, and Hand questionnaires were administered. RESULTS: Thirty-eight patients received Artelon implants into the CMC joint, and 6 were lost to follow-up. Twelve of 32 patients (37%) required revision surgery with removal of implant and salvage arthroplasty. Twenty patients with nonrevised Artelon implants were compared with 10 patients who received 13 LRTI procedures. Patients with Artelon had significantly less pain improvement compared to those receiving the LRTI procedure. In addition, satisfaction was significantly decreased. There was no significant difference in any other functional or quality of life measures. CONCLUSIONS: In our practice, use of the Artelon joint spacer resulted in an explantation rate of 37%. Due to these findings, we have abandoned its use for treatment of basilar thumb osteoarthritis. In contrast to previous studies, pain and satisfaction are worse in patients with intact Artelon spacers than those who had received LRTI.

Brachioplasty outcomes: a review of a multipractice cohort.

BACKGROUND: Upper arm deformities secondary to massive weight loss or senile elastosis have led to an increased demand for aesthetic contouring procedures such as brachioplasty. METHODS: The records of all patients who underwent a brachioplasty procedure from a multipractice medical center were reviewed. Outcomes measured included patient demographics, operative interventions, and postoperative course. RESULTS: Ninety-six patients were analyzed. Fifty-three patients (55.2 percent) underwent a concomitant procedure, with 53.1 percent undergoing arm liposuction at the time of brachioplasty. Major and minor complications rates were 17.7 percent and 44.8 percent, respectively. Common complications included hypertrophic scarring (24.0 percent) and infection (14.6 percent). The total revision rate was 22.9 percent, with residual contour deformity (40.9 percent of revisions) and hypertrophic scarring (36.4 percent of revisions) representing the most common causes for revision. Patients who underwent a previous bariatric procedure were at an increased risk of developing a major complication (p = 0.02). Concomitant upper arm liposuction and concomitant procedures were not associated with a significantly increased complication rate. CONCLUSIONS: Brachioplasty, despite being an effective treatment for contour irregularities of the upper arm, is associated with significant revision and complication rates. Post-bariatric surgery patients should be informed of the potential for increased complications. Additional procedures performed at the time of brachioplasty do not significantly increase complications. Liposuction of the upper arm can be performed safely in conjunction with brachioplasty.

Outcomes of traditional cosmetic abdominoplasty in a community setting: a retrospective analysis of 1008 patients.

BACKGROUND: Abdominoplasty is one of the most commonly performed cosmetic operative procedures. Few large studies have examined outcomes of cosmetic abdominoplasty in a community setting. The authors explored postoperative outcome and the preoperative and intraoperative factors that may contribute to these complications. METHODS: A retrospective review of consecutive patients undergoing abdominoplasty over an 11-year period was performed. Baseline patient demographics, intraoperative technique, and postoperative outcomes were recorded. Preoperative and intraoperative characteristics were analyzed to determine characteristics that predispose patients to complications and undesirable outcomes. RESULTS: The 1008 study patients underwent either a full or modified abdominoplasty with a total complication rate of 32.6 percent. The most common complication was seroma (15.4 percent). Liposuction of the abdominal flap was performed in 469 patients (46.5 percent) and liposuction of the flanks was performed in 555 patients (55.1 percent). Chi-square analysis followed by logistic regression revealed that liposuction of the flanks and abdomen was independently associated with seroma formation in addition to major and minor complications (p < 0.05). CONCLUSIONS: Seroma formation following abdominoplasty is the most common complication. Concomitant liposuction of the flanks and abdomen with the addition of aggressive undermining leads to higher seroma rates. This association is likely multifactorial and may be secondary to increased resorptive demands placed on the abdominal lymphatics in the setting of greater dead space and larger fluid shifts as a result of liposuction. To reduce seroma rates, surgeons should avoid aggressive liposuction and undermining, particularly in high-risk patients.

The impact of antibiotic impregnated PICC lines on the incidence of bacteremia in a regional burn center.

INTRODUCTION: Peripherally inserted central catheters (PICCs) have been used increasingly in burn patients who often have decreased intravascular volumes and obtaining intravascular access for resuscitative efforts can be difficult. A potentially serious complication is bloodstream infection. The purpose of our study is to examine the impact of antibiotic impregnated PICC lines on the bacteremia rate in a regional burn center. METHODS: Consecutive patients admitted to the burn unit and receiving an antibiotic impregnated PICC line were included in the study. Baseline demographics and bacteremia rate was recorded. A retrospective chart review was then undertaken of the 30 consecutive patients admitted to the burn unit and receiving a PICC line prior to the study period. RESULTS: Nineteen patients were enrolled over the two-year period. The bacteremia rate for the study group was 0% compared to the 50% bacteremia rate of the retrospective control group (p=<0.001). CONCLUSION: Antibiotic impregnated PICC lines decrease the bacteremia rate in our burn population. This has potential benefits for both patient morbidity and mortality as well as potential cost savings for the healthcare system.

Vertical reduction mammaplasty utilizing the superomedial pedicle: is it really for everyone?

BACKGROUND: Classically, the vertical-style reduction mammaplasty utilizing a superomedial pedicle has been limited to smaller reductions secondary to concerns for poor wound healing and nipple necrosis. OBJECTIVES: The authors reviewed a large cohort of patients who underwent a vertical-style superomedial pedicle reduction mammaplasty in an attempt to demonstrate its safety and efficacy in treating symptomatic macromastia. METHODS: A retrospective review was performed of 290 patients (558 breasts) who underwent a vertical-style superomedial pedicle reduction mammaplasty. All procedures were conducted by one of 4 plastic surgeons over 6 years (JDR, MAA, DLV, DRA). RESULTS: The average resection weight was 551.7 g (range, 176-1827 g), with 4.6% of resections greater than 1000 g. A majority of patients (55.2%) concomitantly underwent liposuction of the breast. The total complication rate was 22.7%, with superficial dehiscence (8.8%) and hypertrophic scarring (8.8%) comprising the majority. Nipple sensory changes occurred in 1.6% of breasts, with no episodes of nipple necrosis. The revision rate was 2.2%. Patients with complications had significantly higher resection volumes and nipple-to-fold distances (P = .014 and .010, respectively). CONCLUSIONS: The vertical-style superomedial pedicle reduction mammaplasty is safe and effective for a wide range of symptomatic macromastia. The nipple-areola complex can be safely transposed, even in patients with larger degrees of macromastia, with no episodes of nipple necrosis. The adjunctive use of liposuction should be considered safe. Last, revision rates were low, correlating with a high level of patient satisfaction.

The double-opposing buccal flap procedure for palatal lengthening.

BACKGROUND: Velopharyngeal dysfunction has been treated with either a pharyngeal flap or sphincteroplasty with varying degrees of success. Both of these entities have their own series of problems, with sleep apnea and nasal mucous flow disruptions at the forefront. The purpose of this study was to review the senior author's (R.J.M.) experience performing the double-opposing buccal flap for palatal lengthening. METHODS: All patients who were treated with double-opposing buccal flaps between October of 1994 and July of 2007 were reviewed. These patients presented with varying degrees of velopharyngeal dysfunction showing some degree of velar movement at the time of surgery. Preoperative and postoperative speech results were reviewed for comparison. RESULTS: Twenty-seven patients underwent palatal lengthening, with an average length of follow-up of 58 months. Distal flap necrosis occurred in two patients. The level of intelligibility (65.4 percent versus 95.5 percent) and resonance (moderately hypernasal versus normal resonance) improved significantly postoperatively (p < 0.0001). Only one patient required the addition of a pharyngeal flap for persistent velopharyngeal dysfunction, and there were no postoperative issues with sleep apnea. CONCLUSIONS: The double-opposing buccal flap is an effective technique for lengthening the palate, improving speech, and decreasing the risks of postoperative sleep apnea. All patients experienced a dramatic improvement in their resonance and intelligibility. This technique appears most effective in patients with intact velar movement who demonstrate a small to moderate posterior velar gap. The double-opposing buccal flap is a useful means of treating velopharyngeal dysfunction, thus serving as an adjunct when improving pharyngeal closure.
