RESUMO

BACKGROUND AND OBJECTIVE: Wound healing inevitably leads to scarring, which leads to functional and cosmetic defects. It is the goal of this study to investigate the immediate use of ablative fractional CO2 lasers to reduce post-operative scarring secondary to surgical wounds. STUDY DESIGN/MATERIALS AND METHODS: In this prospective controlled study, 20 surgical incisions were created on each of three pigs. Fifteen of the incisions were treated with an ablative fractional CO2 laser at one of three laser settings. The remaining five incisions served as a control. Punch biopsies were taken post-operatively over time. Digital photographs were taken of each incisional scar at each time period. Blinded evaluators used a previously verified scoring system to score photographs of the incisional scars taken at the 6 month time period. RESULTS: With regards to the comparison between the three individual laser treatment groups and the control, there were no statistically significant effects for treatment (P = 0.40), time (P = 0.48), or for the interaction of time and treatment (P = 0.57). With regards to the visual assessment tool, there were no statistically significant differences between treatments for Overall Appearance (P = 0.21) or for Total Score (P = 0.24). CONCLUSIONS: In the limited setting of this pilot study, treatment of surgical incisions with ablative fractional CO2 lasers does not significantly lessen scar formation. In addition, photographic analysis was not able to demonstrate a significant difference. Future studies on this topic will need a larger sample size to better answer whether a statistically significant difference may exist. Lasers Surg.

RESUMO

BACKGROUND: Chronic ischemia of the hand in the setting of atherosclerotic disease is a challenging problem that leads to serial amputations and significant morbidity. Salvage using an in situ venous bypass has been described. In selected cases, leaving the vein in situ for bypass allows a good size match for anastomosis at the wrist or palmar arch. Due to the rarity of the condition, there is a paucity of data regarding the efficacy of this technique. METHODS: Outcomes in 23 consecutive patients that underwent a total of 25 in situ vein grafts over a 16-year period were retrospectively reviewed. RESULTS: Eighteen were men and 5 were women with a mean age of 61 years. Target vessels at the wrist or palmar arch were identified on preoperative vascular imaging. The cephalic vein (n = 19, 76%) was most commonly used followed by the basilic vein (n = 6, 24%). Overall patency rate at a mean follow-up period of 12.1 months was 92%. Success as determined by both symptomatic improvement and resolution of the ischemic changes or toleration of revision amputation was achieved in 16 (64%) cases. Postoperative complications occurred in ten cases (40 %). Progression of ischemia occurred in 7 cases (28 %) and 3 (12 %) of these cases required a hand amputation. CONCLUSIONS: In situ vein grafts in the upper extremity offer good short-term patency rates and can be used for salvage of chronic hand ischemia.

RESUMO

BACKGROUND: Cosmetic rhinoplasty has great potential to change a patient's appearance. It also carries the very real risk of patient dissatisfaction and request for revision. Although there have been many published patient series studying various aspects of rhinoplasty, questions remain regarding revision rates, as well as risk factors for complications, dissatisfaction, and revision. OBJECTIVES: The authors investigate the rate of cosmetic rhinoplasty revision at a plastic surgery group practice and identify risk factors for revision. METHODS: Medical records were retrospectively reviewed for all patients who presented to a single multisurgeon practice for primary rhinoplasty, septorhinoplasty, and revision rhinoplasty between 1998 and 2008. Patient demographics, preoperative complaints, preoperative physical examination findings, detailed operative data, and postoperative outcomes were abstracted from the charts. Complication rates, revision rates, and postoperative patient satisfaction were calculated and analyzed for identifiable risk factors. RESULTS: Of 369 consecutive cosmetic rhinoplasties performed during the study period, 279 (72.7%) were conducted with an open approach. The overall complication, dissatisfaction, and revision rates were 7.9%, 15.4%, and 9.8%, respectively. Postoperatively, most patients (87%) were identified by their surgeons as having had successful anatomical correction of their nasal deformity. History of previous nasal operation or facial fracture, lack of anatomical correction, and occurrence of postoperative complications were associated with both revision and dissatisfaction (P < .05). Failure to address the nasal tip at the time of primary rhinoplasty was associated with a higher level of dissatisfaction. CONCLUSIONS: Cosmetic rhinoplasty is one of the most challenging procedures in plastic surgery; however, these data indicate that a high level of patient satisfaction is attainable within a plastic surgery group practice if certain factors are considered. Specifically, surgeons should be aware of risk factors that are potentially associated with dissatisfaction and revision. LEVEL OF EVIDENCE: 4.

RESUMO

BACKGROUND: The tongue-lip adhesion has undergone several modifications in an attempt to reduce surgical complications and failure rates. Current techniques rely on the use of a button at the tongue base for suspension, which raises concerns about possible aspiration and interference with oral motor function and bottle-feeding. A new technique for tongue-lip adhesion is proposed that adds a tongue suspension to the standard surgical adhesion. METHODS: A total of 22 patients with Pierre Robin sequence who received a tongue-lip adhesion via a tongue suspension technique were reviewed. The surgical technique differs from the standard surgical approach by the use of a suture weave across the base of the tongue instead of a standard button to suspend the tongue anteriorly. RESULTS: Average age at the time of tongue-lip adhesion was 13.9 days, with a mean operative time of 88.8 minutes. A marked improvement in postoperative oxygenation was seen in the majority of patients. One dehiscence occurred secondary to a traumatic postoperative extubation, eventually requiring a tracheostomy for subglottic stenosis. CONCLUSION: A technical innovation for performing a tongue-lip adhesion using a tongue suspension in conjunction with a standard transverse adhesion of the lip is described. The advantage of the tongue-lip adhesion with suspension includes immediate postoperative extubation, as well as removal of concerns regarding button aspiration and possible interference in early developmental oral motor function and bottle-feeding. This technique is reproducible, expanding the craniofacial surgeon's armamentarium for the management of difficult airways in Pierre Robin sequence.

RESUMO

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.

RESUMO

Reconstruction of the craniofacial skeleton has undergone a significant evolution during the past century. Initially, the use of autogenous bone grafts from various sites was the criterion standard. However, owing to donor site morbidity and lack of sufficient bone for large defects, surgeons have relied on various bone substitutes. Hydroxyapatite (HA) has served as an alternative to autogenous grafts, but questions regarding biocompatibility, risk of infection, and slow set times have hampered its acceptance. This article serves as a review of a single surgeon's experience using HA in the craniofacial skeleton. Eighteen patients receiving HA between March 2000 and November 2006 were observed. Sixteen underwent recontouring of skull-based bone defects, and 2 underwent recontouring for nasal and alveolar defects. The mean amount of HA used in each patient was 30.2 g. For large contour irregularities, the maximum thickness of HA used was 8 mm. The size of bone defects ameliorated averaged 4.8 cm(2). Complications occurred in 3 (16.7%) of 18 patients and included scalp hematoma and superficial cellulitis. In addition, 1 patient developed a facial abscess after placement along the alveolar floor, which necessitated removal. Hydroxyapatite represents a viable alternative to autogenous bone grafts when used in the correct manner. Hydroxyapatite should be used only for smaller defects or used in conjunction with absorbable plates when attempting to fill larger defects. Use of HA for nasal piriform augmentation or alveolar bone grafting should not be considered owing to problems with late infections.

RESUMO

BACKGROUND: Despite the effectiveness of ablative CO(2) laser resurfacing for facial rejuvenation, its application has been limited owing to an undesirable side-effect profile, including prolonged hyperemia and potential pigmentary changes. However, newer fractional CO(2) laser technology has reduced the recovery time and led to decreases in postprocedural hypo- and hyperpigmentation. OBJECTIVES: The authors investigate the application and outcomes of ablative fractional technology in a private cosmetic surgery practice. METHODS: In this retrospective cohort study, the charts of patients who received fractional CO(2) laser resurfacing between March 2007 and May 2008 were reviewed. Data regarding patient demographics, pretreatment regimens, detailed operative data, and posttreatment findings were obtained. The length of hyperemia (less than five weeks, five to eight weeks, and more than eight weeks), complication rates, and revision rates were analyzed. A satisfaction survey was also sent to all patients. RESULTS: Throughout the 19-month study period, 97 patients received 101 treatments with an average follow-up of 4.5 months. Full-face laser resurfacing was performed in 81.1% of patients, with 64.3% receiving their treatment under local anesthesia without sedation. Length of hyperemia was less than five weeks in 93%, five to eight weeks in 5.9%, and more than eight weeks in 0.9% of patients. Hyperpigmentation (9.9%), milia (6.9%), acne breakout (5.9%), and transient ectropion (0.9%) were less common. Patient satisfaction surveys revealed that a majority of patients were satisfied with their results. CONCLUSIONS: New fractional CO(2) laser skin resurfacing is associated with shorter periods of hyperemia, resulting in shorter recovery time in comparison with older ablative technology. The side-effect profile is minor and infrequent. This new technology provides significant clinical improvement with high patient satisfaction.

RESUMO

BACKGROUND: Standard methods of cleft palate repair rely on existing palatal tissue to achieve closure. These procedures often require relaxing incisions, causing scars and growth restriction, and may result in insufficient palatal length and suboptimal positioning of the velar musculature. The Furlow double opposing Z-plasty improves palatal length and repositions the velar musculature; however, relaxing incisions may still be needed. The addition of buccal flaps to the Furlow repair obviates the need for relaxing incisions and allows the Furlow repair to be used in wide clefts. METHODS: A retrospective review was performed on 505 patients; all patients were treated with the double opposing Z-plasty plus or minus buccal flap approach. Outcomes included nasal resonance, secondary speech surgery, and postoperative complications. A comparison was made between patients treated with double opposing Z-plasty alone and those treated with double opposing Z-plasty plus buccal flaps. RESULTS: The average nasal resonance score was 1.38 and was equivalent in both the double opposing Z-plasty alone and with buccal flap groups, despite significantly more wide clefts in the buccal flap group (56 percent versus 8 percent). The secondary surgery rate for velopharyngeal insufficiency was 6.6 percent and the fistula rate was 6.1 percent. The large fistula rate (>2 mm) was 2.7 percent. CONCLUSIONS: The double opposing Z-plasty plus or minus buccal flap approach is a useful alternative to standard palate repairs. Speech outcomes were excellent, even in wider clefts, and postoperative complications were minimal. Buccal flaps allow the benefits of the Furlow repair to be applied to any size cleft, without the need for relaxing incisions. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

RESUMO

BACKGROUND: Iatrogenic shell injury during the implantation and explantation of silicone gel breast implants may lead to eventual device failure. Identification of the patterns of injury caused by surgical instruments is important when attempting to characterize the cause of shell rupture. Understanding the true causes of device failure may help with its prevention. The purpose of this study was to microscopically characterize patterns of shell injury induced by various surgical instruments. METHODS: Textured and smooth silicone gel implants were intentionally damaged with a variety of surgical instruments. Various scalpels and surgical scissors ranging in fineness were used to create full-thickness injuries in the implant shell. Optical microscopy and scanning electron microscopy were then used to image the injured area to determine patterns of injury. RESULTS: Full-thickness striations across the thickness of the shell could be seen with damage caused by scissors. The density of these striations correlated directly with the fineness of scissors used. No striations were seen with injuries caused by scalpels. CONCLUSIONS: Striations were only observed in injuries caused by scissors and suture needles. Striation density correlated with the coarseness of the cutting edge. No such striations were seen in shells damaged by a scalpel even when the angle of approach was changed. This difference can be of assistance in distinguishing between scissors versus scalpel injury of an implant shell.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: In 2005, the McGhan Style 153 double-lumen breast implant was removed from the market secondary to a higher rupture rate when contrasted with other implants in the Core Study group. The high rupture rate was attributed to the development of a posterior tear in the shell where the inner implant is bonded to the posterior wall of the device. The purpose of this study was to report the existing rupture rate and describe the apparent mechanism of failure in the Style 153 double-lumen breast implant. METHODS: Ninety-seven patients (157 implants) who received the McGhan Style 153 double-lumen breast implant by the senior author were reviewed. Intraoperative observations and photographic images of ruptured implants were reviewed and characterized based on severity and location of implant rupture. RESULTS: With a mean length of follow-up of greater than 6 years (82 months), the rupture rate was 19.1 percent per implant. Physical examination (60 percent) was the most common method of rupture detection. Ruptures tended to occur in the marginal aspect (63 percent) of the implant. Only three ruptures occurred secondary to a disruption of the inner bladder from the posterior portion of the implant. CONCLUSIONS: The rupture rate of the Style 153 double-lumen breast implant is higher than previously thought, with a rate of 19.1 percent. A majority of ruptures occurred in the peripheral aspects of the implant. It is postulated that these ruptures were likely secondary to fold flaws that led to failure of the implant shell.

RESUMO

Deep sternal infections secondary to bony instability and malunion, can result in mediastinitis. Previous authors have described the use of prophylactic rigid plate fixation in high-risk patients. The purpose of our study is to review the use of prophylactic sternal platting with pectoralis advancement flaps in high-risk patients with a history of chest irradiation. Fourteen patients (July 2003-September 2008) with a history of chest irradiation who underwent a median sternotomy followed by prophylactic rigid plate fixation of the sternum were reviewed. Breast cancer was the most common etiology of chest irradiation (n=11, 78%). The average EuroSCORE was 24.06% with 72% of patients having a preoperative New York Heart Association (NYHA) class≥III. There were no episodes of sternal non-union, mediastinitis or death. Follow-up was 100% with a 0% 30-day and a 7.1% one-year mortality rate (non-cardiac). A comparison between mean preoperative left ventricular ejection fraction (LVEF) (49.6%) and postoperative LVEF (59.7%) was statistically significant (P<0.0001). All living patients currently maintain a NYHA class I/II. Prophylactic rigid plate fixation and pectoralis flap coverage decreases the risk of developing sternal dehiscence and postoperative wound complications and should therefore be considered in high-risk patients with a history of chest irradiation.

RESUMO

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.

RESUMO

An accurate measurement of BSA involved in patients injured by burns is critical in determining initial fluid requirements, nutritional needs, and criteria for tertiary center admissions. The rule of nines and the Lund-Browder chart are commonly used to calculate the BSA involved. However, their accuracy in all patient populations, namely obese patients, remains to be proven. Detailed BSA measurements were obtained from 163 adult patients according to linear formulas defined previously for individual body segments. Patients were then grouped based on body mass index (BMI). The contribution of individual body segments to the TBSA was determined based on BMI, and the validity of existing measurement tools was examined. Significant errors were found when comparing all groups with the rule of nines, which overestimated the contribution of the head and arms to the TBSA while underestimating the trunk and legs for all BMI groups. A new rule is proposed to minimize error, assigning 5% of the TBSA to the head and 15% of the TBSA to the arms across all BMI groups, while alternating the contribution of the trunk/legs as follows: normal-weight 35/45%, obese 40/40%, and morbidly obese 45/35%. Current modalities used to determine BSA burned are subject to significant errors, which are magnified as BMI increases. This new method provides increased accuracy in estimating the BSA involved in patients with burn injury regardless of BMI.

RESUMO

BACKGROUND: One of the goals of plastic surgery residency programs is to provide effective training in aesthetic surgery. Recently, programs have adopted the idea of chief clinics to provide senior residents with the opportunity to perform cosmetic surgery with an increased level of autonomy. The goal of this article is to characterize chief clinics currently in place and their usefulness in providing effective training in plastic surgery under the precepts set forth by the Accreditation Council for Graduate Medical Education. METHODS: A survey was created focusing on six broad categories: respondent identifier, clinic structure, clinic monetary earnings, patient demographics, procedures, and educational utility. Surveys were distributed to all plastic surgery residency programs targeting current and recently graduated chief residents, and program directors. RESULTS: A total of 123 surveys were returned. Eighty of the 88 plastic surgery residency programs (91 percent) were represented. Of the programs responding, 71.3 percent (57 programs) had a chief resident clinic. Thirty-two of the respondents (43.8 percent) reported that 100 percent of the procedures performed were cosmetic in nature. Programs differed widely on their frequency of occurrence and support staff available. A majority of respondents felt these clinics enhanced resident understanding of the six Accreditation Council for Graduate Medical Education core competencies. CONCLUSIONS: A majority of plastic surgery training programs use the chief clinic model to enhance resident education. These clinics vary in makeup and case distribution but serve as an effective way of teaching autonomy, surgical maturity, and the six Accreditation Council for Graduate Medical Education core competencies.

RESUMO

Outdoor recreational fires are a frequent occurrence during the summer months and can be associated with burns resulting in significant morbidity. Both pediatric and adult populations can be affected, and their mechanism of injury is often different. Understanding these mechanisms is important when designing prevention programs. It is the goal of this study to review our experience with outdoor recreational fires. All patients who presented to Spectrum Health Blodgett Regional Burn Unit for burns secondary to an outdoor recreational fire over an 8-year period were reviewed. Demographic data, mechanism of injury, body area involved, TBSA burned, treatments undertaken, and subsequent complications were recorded. Pediatric patients (aged 16 years and younger) were analyzed independently, and risk factors were determined. A total of 329 patients suffered burns secondary to outdoor recreational fires over the length of the study. More than 35% required inpatient treatment, with an average length of stay of 4.8 days. Hands were the most frequently affected body part, with the mean TBSA involved being 3.5%. Ninety-four patients (28.6%) required split-thickness skin grafting. The most common mechanism of injury in both adult and pediatric populations was falling into an ongoing fire. Wound infection was the most common complication. Alcohol intoxication was associated with a higher burn severity and complication rate. Pediatric patients represented 39.8% of the sample. Burns secondary to outdoor recreational fires are associated with significant morbidity. Adult prevention programs should target awareness with respect to alcohol consumption and campfires secondary to the morbidity associated with these injuries. Pediatric patients are particularly susceptible, and parents should remain diligent about campfire safety and be educated about the inherent dangers of both active and extinguished fires.

RESUMO

The number of abdominoplasties performed in the United States has been steadily increasing over the past decade. A large proportion of these patients are bariatric patients who remain obese despite prior weight-reduction surgery. This study was done to review the experience of patients undergoing abdominoplasty at a university hospital. A retrospective chart review of 206 consecutive patients was performed. The overall complication rate was 37.4%. Major complications [hematoma requiring surgical intervention, seroma requiring aspiration or surgical drainage, cellulitis or abscess requiring hospitalization and intravenous (IV) antibiotics, deep vein thrombosis (DVT), and pulmonary embolism (PE)] occurred in 16% of patients. The rate of minor complications (hematoma or seroma requiring no intervention, epidermolysis, small-wound dehiscence, neuropathic pain, and minor cellulitis) was 26.7%. Obese patients had a significantly increased risk of developing major complications as compared with nonobese patients (53.4% versus 28.8%, P = 0.001). An in-depth analysis of all complications and risk factors was done.
