Update on Liposuction: What All Plastic Surgeons Should Know.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Understand the types of tumescence available for liposuction. 2. Explain the various modalities available for liposuction. 3. Describe the patient selection, staging, and complications associated with debulking liposuction. 4. Describe ways to optimize outpatient liposuction. SUMMARY: Liposuction is one of the most common procedures performed by board-certified plastic surgeons and is likely greatly underestimated, given underreporting of office procedures and the number of non-plastic surgeons performing these operations. With the ever-increasing popularity of liposuction, various methodologies and technology have been designed to make this task simpler and faster for the surgeon and hasten the recovery for the patient. In the past 10 years, over 50 devices or techniques have been released to assist, refine, or altogether replace liposuction. With the advent of these newer tools, a thorough Continuing Medical Education study was performed to review the available literature.

Deep and Superficial Closure.

All operative interventions in plastic surgery have one thing in common: closure of an incision or wound at the conclusion of the procedure. For many years, the only option to accomplish this task was the use of sutures. Today's surgeon, however, has many more options available, ranging from smooth to barbed suture, external to internal staples, internal to external adhesive glues, and incisional negative-pressure wound therapy. These devices are designed with the goal of making wound closure more rapid and secure, and decreasing postoperative sequelae. This paper reviews methods available to perform incisional closure and the published clinical data regarding their use.

Equivalent outcomes with once versus thrice weekly dressing changes in midline laparotomy wounds treated with negative pressure wound therapy.

BACKGROUND: While negative pressure wound therapy (NPWT) has been used for decades, there is a paucity of data regarding the appropriate length of time between dressing changes. METHODS: This was a prospective, randomized control trial examining time to wound closure in open midline laparotomy wounds treated with NPWT. The control group received the standard thrice weekly sponge changes (thrice) and the treatment group received once weekly sponge changes (once). RESULTS: 44 patients met study criteria over a 3-year period. There was no difference in NPWT duration between the two groups (37.1 vs 34.7 days, p = 0.7324), even after adjusting for potential confounders (p = 0.8091). No differences were found in initial wound size or reduction. The wound complication profile was similar for both groups. CONCLUSION: There is no difference in time to wound closure or complications with NPWT dressing changes once a week compared to the standard three times a week.

Common Complications and Management After Massive Weight Loss Patient Safety in Plastic Surgery.

This article discusses strategies to prevent and manage the most common complications seen in body contouring surgery. General approaches to avoidance and treatment of these complications are addressed, including wound dehiscence, delayed wound healing, seroma, hematoma, infections of the surgical or remote sites, lymphedema, suture extrusion, and fat necrosis. Procedure-specific complications and pearls to avoiding complications in these cases are presented. Difficult problems, such as management of the disappointed patient, also are discussed.

Breast Reshaping After Massive Weight Loss.

The technique of dermal suspension, parenchymal reshaping mastopexy is a useful procedure for patients with massive weight loss with a typical presentation. The operation is tailored to the individual deformity, powerfully reshapes the breast, and can be safely combined with other commonly performed procedures. It is long-lasting and associated with minor complications that are easily treated in an office setting.

Characterizing the Saddlebag Deformity After Lower Body Lift.

BACKGROUND: One of the commonly cited sequelae of lower body lift is recurrence of the saddlebag deformity. However, there are currently no data that characterize the evolution of the saddlebag following lower body lift, nor is there a classification scheme to objectively quantify the severity of the deformity. OBJECTIVES: The authors aimed to develop a grading scale to score the severity of the saddlebag deformity and, using this, determine the short- and long-term changes in the saddlebag following lower body lift. METHODS: Using the Pittsburgh Rating Scale, the Pittsburgh Saddlebag Rating Scale, a 4-point Likert scale, was developed to score the saddlebag deformity. Patients who underwent lower body lifts were parsed from a prospectively maintained database. Two educated observers independently reviewed both preoperative and postoperative photographs and graded the saddlebag deformity according to the Pittsburgh Saddlebag Rating Scale. RESULTS: Seventy-nine patients met inclusion criteria, including 5 males and 74 females. The average saddlebag score preoperatively was 1.34, while the average scores at short- and long-term follow up were 1.28 and 1.42, respectively. No significant differences in saddlebag severity scores were noted between preoperative and short- or long-term postoperative time points (P > 0.05). CONCLUSIONS: This is the first study to objectively demonstrate the postoperative changes in the saddlebag following lower body lift. Results demonstrated that lower body lift does not effectively treat the saddlebag as the deformity only slightly improved in the short-term window but recurred within a year of surgery.

Anthropometric Effect of Mucoperiosteal Nostril Floor Reconstruction in Complete Cleft Lip.

OBJECTIVE: The primary objective of this study was to investigate whether growth impairment in children with cleft lip is caused by reconstructing the nostril floor using lateral nasal and premaxillary mucoperiosteal flaps. The effects on growth and symmetry of tip rhinoplasty at the time of initial repair, as well as cleft sidedness are similarly investigated. METHODS: An Institutional Review Board approved, retrospective, single-center study at an academic children's hospital from July 2005 to 2010 was designed. Seventy-four patients with unilateral cleft lip ± palate were followed postsurgical repair of the cleft lip deformity. Serial digital photographs from clinical encounters were analyzed. Anthropometric measurements of 10 soft tissue landmarks were extracted from anteroposterior and submental vertex views at serial visits; growth velocities, defined as c = Δd/Δt, were generated using linear mixed models on selected measurements to study time-related changes on growth. The effects on growth and symmetry of primary tip rhinoplasty on perinasal landmarks and nostril floor reconstruction with medial and lateral nasal mucoperiosteal flaps on perioral and perinasal landmarks were analyzed. Proxies for midfacial height (en-al) and maxillary height (al-ch) were used to evaluate the effect of mucoperiosteal dissection, whereas nostril width, height, and angle were used as proxies to evaluate the effects of tip rhinoplasty. RESULTS: Seventy-four patients met the inclusion criteria. Midface height (En-Al) growth velocity was 0.014 mm/month and maxillary height (Al-Ch) was relatively stable at -0.0059 mm/month with no difference between the subgroups. Nostril height growth was -0.0046 mm/month, nostril width was 0.03 mm/mo, and nostril angle -0.09 °/mo showed no difference between patient with or without primary tip rhinoplasty. Patients with complete cleft showed more asymmetry than those with incomplete clefts in lip and maxillary landmarks at T0 (P < 0.001). CONCLUSIONS: Mucoperiosteal reconstruction of the nostril floor at the time of lip repair does not affect anthropometric growth velocities over a 5-year follow-up. Within the limitations of the selected landmarks, primary tip rhinoplasty did not significantly improve symmetry at 5 years, but also did not affect the growth of the nose. Patients with complete clefts display more postoperative asymmetry than those with incomplete clefts.

Safety and efficacy of recombinant human bone morphogenetic protein 2 on cranial defect closure in the pediatric population.

BACKGROUND: Traditional reconstructive options for cranial defects include autogenous bone graft, bone substitutes, and synthetic materials. The established standard for repairing cranial defects is autogenous bone. However, young children do not have abundant donor sites for bone harvest, which leads to challenges in closing calvarial defects. Synthetic materials are not ideal alternatives because they require subsequent retrieval and are prone to infection. Their long-term effects on growth of the skull are also not well studied. Bone morphogenetic protein 2 (BMP-2), are shown to positively affect closure of cranial defects in animal models. We present a study comparing the efficacy and safety of closure of cranial defect with bone graft augmented with recombinant human BMP-2 (rhBMP-2) and compared with a series of patients treated with bone graft alone. METHODS: This study is a retrospective multicenter evaluation of 36 patients spanning 5 years. Twenty-one patients undergoing cranial defect closure augmented with rhBMP-2 were compared with 15 patients who underwent cranial defect closure using cranial bone shavings alone. We measured preoperative and postoperative defect size on volumetric computed tomographic scan reconstructions to compare defect sizes. RESULTS: The rhBMP-2 group had slightly increased proportional closure compared with the control group, 86% versus 76% (P < 0.018), respectively. Two patients in the rhBMP-2 group had postoperative fusion of a suture that was known to be patent at the time of cranial defect closure. No instances of brain edema, herniation, airway compromise, or other adverse effects directly attributable to rhBMP-2 were observed. CONCLUSIONS: Bone morphogenetic protein 2 may increase the amplitude and uptake of cranial bone grafts in cranial defect closure. This study shows that defect sizes of up to 16 cm can be reliably closed using this technique. Postoperative fusion of uninvolved sutures in 2 patients indicates that rhBMP-2 may have unreported adverse effects; consideration of this finding should be weighed against the benefit of improved closure of calvarial defects.

The rotational advancement of medial plantar flap for coverage of foot defect: a case report.

This case describes the use of the medial plantar artery flap used to cover a lateral foot wound in a 19-year-old male with a history of spina bifida. The original operative plan was for coverage with a medial plantar flap based distally on retrograde flow through the lateral plantar artery; however, this had to be revised intraoperatively as his vascular anatomy was not adequate to support a flap of this type. Thus, advancement with rotation modification of the conventional medial plantar flap was performed with good results. At 2-month follow-up, the patient's flap had fully healed, he returned to full weight-bearing status, and he had gross sensation in the sole of his foot. This case illustrates the use of the well-described medial plantar flap by rotating and advancing the flap for reconstruction of defects of the foot.

Civilian gunshot extremity fractures with neurologic injury.

OBJECTIVE: To verify the hypothesis that neurologic injuries are less prevalent in civilian gunshot injuries than that reported in the military literature, and are more likely to occur with concomitant fracture. METHODS: In order to investigate the incidence and patient variables of gunshot injury with neurologic injury, a retrospective chart review was performed at a single urban trauma center over a five-year period. RESULTS: One thousand eight hundred and fifty-one patients with gunshot injuries were treated at our center over the five year study period. Of these, 895 patients (48%) had involvement of at least one extremity and 382 (21%) had concomitant fractures. Seventy-four had concomitant neurologic injury. There was a statistically significant difference of 14% (53/382) and 4% (21/513) (P < 0.0001) between the group with fracture (53 patients) and the group without fracture (21 patients), respectively, in the occurrence of neurologic insult. CONCLUSION: This incidence of neurologic injuries in civilian gunshot injuries is lower than that previously reported in the military population and the presence of a fracture is clearly an additional risk factor for neurologic injury.

The pseudomeningocoele that wasn't: case report of an adult who presented with a late infection of an implant.

This case report describes an unusual case of a 55-year-old male, who presented with what appeared to be a pseudomeningocoele. The patient suffered a skull fracture secondary to a direct blow almost 30 years prior, and had been repaired with a calvarial implant at that time. He had been symptom free for most of that time, until he presented to our institution with a bulging cyst in his left frontal region. Computed tomography revealed a calvarial defect at the site of the cyst and a presumptive diagnosis of pseudomeningocoele was made. As part of his treatment, the patient underwent a lumbar puncture and lumbar peritoneal shunt. These procedures, although temporarily beneficial, ultimately proved unsuccessful in permanently decreasing the size of the cyst. After all conservative measures were exhausted, the team surgically explored the patient: while no communication between the cerebrospinal fluid and cyst could be found, which would be expected in a pseudomeningocoele, there was fibrinous exudates on the implant surface. Tissue cultures showed Staphylococcus epidermidis. This case emphasises the importance of surgical exploration to make a correct diagnosis, as in this case of a sub-clinical calvarial implant infection 30 years after insertion of the implant.
