Background: One-stage mastopexy with breast augmentation is an increasingly popular procedure among patients. In the past 9 years, there has been a 506 percent increase in mastopexy procedures alone. Although some recommend a staged mastopexy and breast augmentation, there are currently no large studies evaluating the safety and efficacy of a one-stage procedure. Methods: A retrospective chart review was conducted of 321 consecutive patients who underwent one-stage mastopexy and breast augmentation. Data collected included the following: patient characteristics, implant information, operative technique, and postoperative results. Complication and revision rates were calculated to evaluate the safety and efficacy of the one-stage procedure. Results: No severe complications were recorded over an average of 40 months’ follow-up. The most common complication was deflation of a saline implant (3.7 percent), followed by poor scarring (2.5 percent), recurrent ptosis (2.2 percent), and areola asymmetry (2.2 percent). Forty-seven patients (14.6 percent) underwent some form of revision surgery following the one-stage procedure. Thirty-five (10.9 percent) of these were for an implant-related issue, whereas 12 patients (3.7 percent) underwent a tissue-related revision. This 10.9 percent implant-related revision rate is less than a previously documented 13.2 percent 3-year reoperation rate for breast augmentation alone. The authors’ 3.7 percent tissue-related revision rate also compares favorably to an 8.6 percent revision surgery rate in patients who underwent mastopexy alone. Conclusions: Although it has been stated that the risks of a one-stage procedure are more than additive, the results of our review suggest otherwise. Although a revision rate of 14.6 percent is significant, it is far from the 100 percent reoperation rate required for a staged procedure.

W. Grant Stevens; Laura K. Pietrzak; Michelle A. Spring

BACKGROUND Cryolipolysis has been shown to be a safe and effective noninvasive procedure for the reduction of localized subcutaneous fat. OBJECTIVES The authors examine the safety, efficacy, and procedural growth of cryolipolysis (via the CoolSculpting device; Zeltiq, Pleasanton, California) in a single plastic surgery practice. METHODS A retrospective chart review was conducted for 528 consecutive patients who underwent cryolipolysis treatment from January 2010 to December 2012. The number of patients, the number of treatment cycles, the average number of cycles per patient, all treatment areas, and all procedural complications were recorded and analyzed. Overall practice growth with the device was also analyzed. RESULTS Over the study period, 1785 anatomic sites were treated with 2729 cycles, primarily in the lower abdomen (28%, n = 490 cycles), upper abdomen (11%, n = 189), left flank (19%, n = 333), right flank (19%, n = 333), inner thigh (6%, n = 111), outer thigh (5%, n = 87), and back (6%, n = 99). The age distribution for men and women was similar (46.6 ± 12.8 years for women and 46.5 ± 12.3 years for men; overall range, 18-79 years). Only 3 cases of mild or moderate pain/neuralgia were reported and resolved in 4 or fewer days. No adverse events were reported. Procedure volume showed consistent growth, with treatment cycles increasing by 823% by 2012. CONCLUSIONS Based on the results in this single plastic surgery practice, cryolipolysis is a safe and effective nonsurgical body contouring method associated with high patient satisfaction that can generate steady, significant business growth.

Is one-stage breast augmentation with mastopexy safe and effective? a review of 186 primary cases

W. Grant Stevens; David A. Stoker; Mark E. Freeman; Suzanne M. Quardt; Elliot M. Hirsch; Robert E. Cohen

BACKGROUND Although some authors have reported that 1-stage breast augmentation with mastopexy does not increase the risks of surgery, recent literature has raised the question of whether better results might be achieved by staging the procedures. OBJECTIVE The authors evaluated the safety and efficacy of 1-stage breast augmentation with mastopexy in their own patients by analyzing long-term complication and revision rates. METHODS A retrospective chart review was performed of 186 consecutive patients who underwent primary 1-stage breast augmentation with mastopexy at a single outpatient facility. Patient data recorded included age, body mass index, smoking status, degree of breast ptosis, and any preoperative asymmetry. Operation-related data recorded included type of mastopexy performed, operating surgeon, length of surgery, American Society of Anesthesiologists level, and concomitant procedures. Data on implant type, volume, and position were also collected. Complication and revision rates were recorded and calculated. RESULTS Ninety-six patients (44%) received saline implants; 104 (56%) received silicone implants. In most cases, textured implants were placed in submuscular pockets. The mean implant volume was 320 cc. Inverted T mastopexy was performed in 60% of cases, circumareolar in 24% of cases, and vertical or crescent accounted for most of the remainder. No severe complications occurred, although 1 patient developed a late infection that required removal of the breast implant. The most common complication was saline implant deflation (5.9%), although saline implants were used in less than half of cases. Thirty-one patients (16.7%) underwent some form of revision surgery within the average 42-month follow-up period. CONCLUSIONS Our review of 1-stage breast augmentation with mastopexy procedures revealed no severe complications. Although the overall revision rate of 16.7% is significant, it is comparable to rates for breast augmentation alone and is significantly lower than the 100% reoperation rate required for a staged procedure. In our experience, it is a safe and effective procedure, although one that is not easy to perform. Patients should be advised of the possibility that a second procedure may be necessary.

BACKGROUND Since the introduction of fourth- and fifth-generation silicone gel implants, manufacturers have conducted several prospective, multicenter trials to examine their safety and efficacy. However, these studies were not standardized with regard to surgeon skill, pocket placement, operative technique, adjunct therapies, or postoperative management. OBJECTIVE The purpose of this study was to examine the surgical outcomes of a single surgeon (WGS) in a consecutive series of breast augmentation cases using a fourth-generation cohesive silicone MemoryGel breast implant (Mentor, Santa Barbara, CA). METHODS A retrospective chart review was conducted to identify all patients who underwent silicone breast augmentation within the Mentor Adjunct Silicone MemoryGel breast implant by a single surgeon (WGS) within a single free-standing outpatient surgical center over a 13-year period (1992 to 2006). For each patient, demographic information, comorbidities, and surgical information (implant size and concomitant surgery) were recorded. In addition, outcomes were analyzed to identify complications and the need for surgical revision. RESULTS A total of 1012 fourth-generation, textured, cohesive silicone gel implants were placed in 511 patients during the 13-year study period. The overall complication rate per implant was 5.5% (n=56 implants in 43 patients). The most common complication was capsular contracture (n=26; 2.6 %) followed by abnormal scarring (n=11; 1.1%). The overall revision rates per patient and per implant were 8.0% (n = 41 patients) and 6.8% (n = 69 implants), respectively. The average time interval between initial implantation and revision was 18.5 months (range, 2 weeks to 26 months). The most common indication for surgical revision was patient desire for implant size change (n=15 patients) followed by Baker class III or IV capsular contracture (n=13 patients). The presence of previous surgery for capsular contracture was not statistically correlated to the need for revision (P= .326). Age (P= .568), previous history of breast surgery (P= .704), and history of smoking (P= .138) were also not statistically correlated to revision. Placement of the implant in the subglandular position (n=30 implants), however, was statistically correlated with need for revision (P< .01). CONCLUSIONS Mentor fourth-generation cohesive silicone gel implants possess a complication and revision profile that is superior to earlier-generation silicone gel implants. Implantation with MemoryGel implants, when standardized with regard to surgeon and operative technique, can have significantly reduced complication and revision rates compared to the Mentor Core Data.

BACKGROUND In the last 15 years, reduction mammaplasty has been increasingly performed on an outpatient basis. Despite this evolution, few outcome studies have been published regarding outpatient breast reduction surgery. OBJECTIVE The authors documented clinical outcomes of reduction mammaplasty performed in an outpatient setting over an 11-year period and compared these results with published normative values in the plastic surgery literature. METHODS A retrospective review was undertaken of 884 reduction mammaplasties in 444 patients at a single outpatient surgical center performed by the senior author (W.G.S.) from 1995 through 2006. In all cases, a laser-assisted, inferior pedicle, Wise pattern, reduction mammaplasty was performed. In addition to demographic and surgical data, complication frequency and type were recorded. Complication data were further stratified into minor and major categories. Potential minor complications included seroma, hematoma, soft tissue infection, dog-ears requiring revision, and small incisional breakdowns or delayed healing of less than 2 cm. Potential major complications included large incisional breakdowns or delayed healing of greater than 2 cm, nipple/areolar necrosis, need for blood transfusion, deep vein thrombosis, pulmonary embolus, myocardial infarction, and death. RESULTS The mean patient age was 38 years (range, 16 to 73 years). Mean body-mass index was 27 (range 17 to 47). The reported preoperative brassiere cup sizes ranged from a 34 C to a 38 K, with a DD being the most common size. The mean preoperative sternal notch-to-nipple distance was 29 cm (range 22 to 54 cm). Forty patients smoked (9%). Mean clinical follow-up was 13 months. Mean total resection weight of breast tissue was 1228 g (range 100 to 5295 g). Mean operative time for reduction mammaplasty was 115 minutes (range 50 to 195 minutes). Nineteen percent of patients underwent multiple procedures, including abdominoplasty, lipoplasty, and facial procedures, with a mean operative time of 132 minutes (range 75 to 345 minutes). The overall complication rate was 14%, with 70 minor complications occurring in 62 patients. Specific minor complications included one seroma, four hematomas, eight soft tissue infections, two of which required a short course of intravenous antibiotics, one patient with dog-ears requiring surgical revision, and 56 small incisional wound breakdowns (< 2 cm). The small incisional breakdowns, which represented the largest group of complications, were further subdivided into 44 minor T-zone wounds, 3 nipple-areolar complex wounds, and 9 wounds of the vertical and horizontal incisions. Three major complications (0.67%) were recorded. Two patients had development of partial nipple/areolar necrosis. A third patient required anticoagulation for a pulmonary embolus diagnosed 10 days after surgery. Statistical analysis of the complication data revealed one significant relationship. Patients with a body mass index above the mean had a 21% complication rate as compared with a 12% rate for those below the mean. Of note, there was no increase in complication rate in the context of multiple procedures. CONCLUSIONS This retrospective series is the largest to date involving outpatient reduction mammaplasty. Complication data derived from this series are comparable to previously published studies and thus support the safety and efficacy of outpatient reduction mammaplasty performed in an accredited facility.

W. Grant Stevens; Remus Repta; Salvatore J. Pacella; Marissa J. Tenenbaum; Robert E. Cohen; Steven D. Vath; David A. Stoker

BACKGROUND Combined cosmetic procedures have become increasingly popular. One of the most common combinations of cosmetic procedures includes abdominoplasty and cosmetic breast surgery. The shortened recovery and financial savings associated with combined surgery contribute to the increased demand for these combined surgeries. OBJECTIVE The goal of this study was to evaluate the safety and efficacy of combined abdominoplasty and breast surgery at a single plastic surgery practice that performs a large volume of these cases. This is an update to a study published in 2006. METHODS A retrospective review was performed for patients who underwent combined abdominoplasty and cosmetic breast surgery during the last 10 years at a single outpatient surgery center. Abdominoplasty inclusion criteria were defined as lower, mini, full, reverse, or circumferential abdominoplasty. Cosmetic breast surgery inclusion criteria were defined as augmentation, mastopexy, augmentation-mastopexy, reduction, or removal and replacement of implants. Pertinent preoperative and intraoperative data were recorded along with complications and revisions. RESULTS There were 268 patients during the 10-year period between 1997 and 2007. There were no cases of death, pulmonary embolism, deep venous thrombosis, or other life-threatening complications. The overall complication rate was 34%. Abdominoplasty seroma and scars requiring revision comprised 68% (n = 74) of the complications. The total revision rate was 13%. CONCLUSIONS Combined abdominoplasty and cosmetic breast surgery was safe and effective in this large series of cases performed at a single plastic surgery practice. The complication and revision rates of the combined surgery were similar to those reported for individually staged procedures.

“Extreme” Cosmetic Surgery: A Retrospective Study of Morbidity in Patients Undergoing Combined Procedures

W. Grant Stevens; Steven D. Vath; David A. Stoker

BACKGROUND It is increasingly common for patients to request that multiple cosmetic procedures be performed during a single operation. The advantages of combined procedures include a single recovery period, reduced surgery costs, and faster patient gratification. Traditional surgical thinking, however, has favored the performance of some procedures individually in an effort to decrease complications associated with prolonged anesthesia. OBJECTIVE The goal of this study was to determine whether performance of combined cosmetic surgery procedures results in increased morbidity. METHODS Two hundred forty-eight abdominoplasties performed by the same surgeon over a 10-year period were reviewed retrospectively. Four groups of procedures were compared: abdominoplasty alone, abdominoplasty combined with breast surgery, abdominoplasty combined with facial surgery, and abdominoplasty combined with both breast and facial surgery. RESULTS No statistically significant differences in complication rates were found among the four groups. The prevalence of morbidity in all groups compared favorably to the parameters established in previous reviews. CONCLUSIONS The results of this retrospective review do not indicate that the combination of cosmetic surgical procedures increases morbidity. The potential benefits of combined procedures may be considered with the expectation of comparably low complication rates.

Cryolipolysis conformable-surface applicator for nonsurgical fat reduction in lateral thighs.

W. Grant Stevens; Eric P. Bachelor

Background Vacuum applicators have been effective for cryolipolysis of the abdomen, flanks, inner thighs, back, chest, and arms. However, the lateral thighs have not been easily treated because fat from this area cannot be easily drawn into a vacuum cup. Objectives The authors investigated the safety and efficacy of a prototype applicator for treatment of “nonpinchable” fat in the lateral thighs. Methods In this prospective, nonrandomized, interventional cohort, multicenter study, a 120-minute unilateral treatment with a prototype conformable-surface applicator was performed on 1 lateral thigh of 40 patients, with the contralateral thigh serving as the control. During follow-up visits at 2 and 4 months, fat reduction was assessed by ultrasound imaging and clinical photography, and patient satisfaction surveys were completed. Results Ultrasound data indicated a 2.6-mm mean normalized reduction in fat thickness—a statistically significant reduction vs the untreated control thigh (P = 7.8E-8). According to patient survey responses, 89% of patients would recommend the procedure to a friend; 86% were satisfied with cryolipolysis for the lateral thighs; 86% noticed visible fat reduction; and 97% were likely to undergo a second treatment. A panel of 3 independent blinded physicians correctly identified baseline and posttreatment clinical photographs in 87% of cases. There were no serious adverse events or unanticipated adverse device effects. Conclusions The cryolipolysis conformable-surface applicator was safe and efficacious for treatment of lateral thigh fat. Clinical photographs and ultrasound results showed significant reduction in fat thickness, and noticeable reduction in undesirable “saddlebag” bulges. Level of Evidence: 3 Therapeutic

Is It Safe to Combine Abdominoplasty with Elective Breast Surgery? A Review of 151 Consecutive Cases

W. Grant Stevens; Robert E. Cohen; Steven D. Vath; David A. Stoker; Elliot M. Hirsch

Background: This study was designed to evaluate and compare the complication rates of patients having abdominoplasty without breast surgery with the rates of those having abdominoplasty with various types of elective breast surgery, including breast augmentation, breast reduction, mastopexy, and mastopexy combined with simultaneous augmentation. Methods: The data collected represent a retrospective chart review of consecutive abdominoplasty procedures performed at a single outpatient facility by the senior surgeon (W.G.S.) over a 15-year period (1989 to 2004). Two groups were compared: patients who underwent abdominoplasty without breast surgery and those who had abdominoplasty with breast surgery. The second group was subdivided by the various types of breast procedures noted above. The minor complications assessed included seromas, hematomas, infections, and small (<5 cm) wound breakdowns. Major complications evaluated included large (>5 cm) flap necrosis, need for blood transfusion, deep vein thrombosis, pulmonary embolus, myocardial infarction, and death. Additional data compiled included age, sex, tobacco use, body mass index, past medical history, American Society of Anesthesiologists physical status level, and operative times. Results: Of the 415 abdominoplasty procedures, 264 (group 1) did not include simultaneous breast surgery. One hundred fifty-one procedures (group 2) involved simultaneous breast surgery, representing 36 percent of the total. Group 2 was further subdivided into those who had breast augmentation surgery (group 2A, n = 50), those who had breast reduction surgery (group 2B, n = 31), those who had mastopexy surgery (group 2C, n = 28), and those who had simultaneous mastopexy and breast augmentation surgery (group 2D, n = 42). Removal and replacement of implants and capsulectomy/capsulotomy procedures were included in the augmentation group (group 2A). There were no major complications, including flap necrosis (open wound >5 cm), blood transfusions, deep vein thrombosis, pulmonary embolus, myocardial infarction, or death. No patients required hospitalization. No statistically significant associations with complications were noted between groups 1 and 2 (chi-square, 0.0045; p > 0.95, not significant). Furthermore, when subdivided by type of breast surgery, no statistically significant associations were noted among subgroups: group 1 versus 2A (chi-square, 0.96; p > 0.05, not significant), group 1 versus 2B (chi-square, 0.032; p > 0.9, not significant), group 1 versus 2C (chi-square, 0.003; p > 0.975, not significant), and group 1 versus 2D (chi-square, 0.83; p > 0.5, not significant). Conclusion: The results of this retrospective review indicate that combining elective breast surgery with abdominoplasty does not appear to significantly increase the number of major or minor complications.

The Endotine: A New Biodegradable Fixation Device for Endoscopic Forehead Lifts

W. Grant Stevens; David B. Apfelberg; David A. Stoker; Steven A. Schantz

BACKGROUND No single technique for fixation of the scalp after endoscopic forehead lift is universally accepted, and complications such as alopecia and regression of elevation have been reported with all techniques. OBJECTIVE This report describes the preliminary results of a study of the Endotine 3.5 forehead device (Coapt Systems, Inc, Palo Alto, CA), a new biodegradable fixation device. METHODS The Endotine 3.5 device consists of a post on the deep side for anchoring it in the skull and five tines on the superior side for engaging the deep scalp tissues. It was tested in 9 patients, with postoperative follow-up ranging from 6 to 8 months. The surgeon evaluated the device for difficulty/ease of use, palpability, postsurgical pain, and wound healing. RESULTS The Endotine 3.5 device produced a secure fixation without problems or complications, although it was often palpable with moderate degrees of sensitivity. It could be applied in less than 2 minutes per side. CONCLUSIONS Our preliminary findings indicate that the Endotine 3.5 forehead device provides rapid, secure fixation without the complications associated with other fixation techniques. After patients reported that it was still palpable up to 24 weeks after implantation, a second-generation polymer that dissolves more rapidly was fabricated. Further studies are under way to evaluate long-term efficacy. (Aesthetic Surg J 2003;23:103-107.).
