Endoscopic transaxillary submuscular augmentation mammaplasty with textured saline breast implants

Transaxillary subpectoral augmentation mammaplasty: a single surgeon's 20-year experience

BACKGROUND

Transaxillary subpectoral augmentation mammaplasty (TASPA) is not widely accepted due to perceived limitations in pocket access, visualization, control, and subsequent risk for postoperative complications. Current published data do little to substantiate or refute those claims.

OBJECTIVE

A retrospective chart review of a single surgeon's 20-year experience with the TASPA technique was undertaken to assess the incidence of total secondary procedures, implant-related revisions, and reoperations unrelated to the implant.

METHODS

The senior author (DCM) performed 1776 primary TASPA procedures from January 1989 through December 2008. Of those, 94 patients did not meet inclusion criteria, leaving a total of 1682 records for analysis. Data reviewed included age, date of surgery, race, implant size and type, manufacturer, and reasons for reoperation.

RESULTS

Average age was 32.7 ± 8.1 years (range, 16-62). Average implant size was 438.5 ± 51.5 cc (range, 270-630). Implants from Allergan/Inamed/McGhan (Irvine, CA), Dow-Corning (Midland, MI), Mentor (Santa Barbara, CA), and Surgitek (Racine, PA) were inserted (n = 2094 saline, n = 1270 silicone). Mean follow-up time was 37.9 ± 45.4 months (range, one month to 19.8 years). Excluding staged mastopexies and treatment for breast cancer, total secondary procedures were required in 225 patients (13.4%). Implant-related revisions included malposition (2.97%), size change (2.5%), and capsular contracture (1.9%). Perioperatively, no infections occurred, and two patients (0.12%) experienced hematoma. Most reoperations (62.8%) were performed through the axilla. Comparison to published data showed an equal or lower rate of capsular contracture, hematoma, and infection with the TASPA approach.

CONCLUSIONS

Given its advantages of an inconspicuous scar, decreased infection, and decreased capsular contracture, TASPA can be safely offered to patients as an option in breast augmentation.

Early results of an endoscopic nipple-sparing mastectomy for breast cancer

BACKGROUND.: Endoscopic mastectomy has been reportedly associated with smaller scars and greater patient satisfaction; however, few reports on this topic have been made. The purpose of this retrospective study was to examine the early results of endoscopic nipple-sparing mastectomy (ENSM) and to investigate the safety of this procedure. METHODS.: Between January 2002 and December 2005, a total of 87 patients with breast cancer but without skin and nipple involvement, including two cases of bilateral breast cancer, underwent E-NSM. In case of bloody nipple discharge and suspicious extension near the nipple as assessed by magnetic resonance imaging, the major ducts within the nipple were cored (nipple coring). In other cases, nipple coring was not performed. RESULTS.: Of the 89 breasts in 87 patients, 42 had tumors of >2 cm and 80 were diagnosed as having invasive carcinoma. Lymph node involvement was observed in 36 procedures. The overall rate of nipple necrosis was 18% (16 of 89). The rate of nipple necrosis among the procedures with nipple coring was statistically higher than that among those without nipple coring (7 of 17, 41%, vs. 9 of 72, 13%) (P = .01). Nipple involvement was observed in 2.2% (2 of 89). After a median follow-up period of 52 months, distant metastasis was observed in nine cases; no local recurrences occurred in this series. CONCLUSIONS.: E-NSM is an oncologically safe procedure and an acceptable method in selected patients requiring a mastectomy. The higher rate of nipple necrosis may have been the result of a technical problem, indicating the need for continued improvement in nipple coring procedures.

Transaxillary breast augmentation: a prospective comparison of subglandular, subfascial, and submuscular implant insertion

BACKGROUND

During the last decades transaxillary breast augmentation (TBA) has gained worldwide acceptance. Breast augmentation via transaxillary access endoscopically assisted in the subglandular, subfascial, and submuscular planes has been previously described. Although TBA is a well-studied procedure, few reports exist concerning the subfascial plane of implant insertion and none exist comparing the three different planes of insertion by TBA.

METHODS

A perspective study to evaluate the outcomes, complications, and patient satisfaction of TBA using the three different planes of implant insertion was performed during 2004-2005. Fifty-three patients fulfilled the inclusion criteria. They were randomly divided into three groups corresponding to the three planes of silicone insertion. All patients had a silicone texturized implant that ranged from 190 to 300 cc. Overall satisfaction with the breast appearance after TBA was rated on a scale of 1-5, where 1 is poor, 2 is fair, 3 is good, 4 is very good, and 5 is excellent. The evaluation was made at the follow-up times of 6 months and 3 years.

RESULTS

There were 18 patients enrolled for the subcutaneous TBA (Group A), 18 for the subfascial TBA (Group B), and 17 for the submuscular TBA (Group C). Axillary incision-related complications occurred in 9% of the patients and included formation of a hypertrophic scar and small-wound dehiscence. There was no hematoma formation and no case of infection. There was one patient from Group A who developed seroma and was treated conservatively. Twenty-seven months postoperatively the same patient developed Baker III capsule contracture, which required silicone implant replacement in the subfascial plane. One case of stretch marks in a young nulliparous woman from Group B did not need treatment. One patient from Group A underwent implant exchange because of implant size dissatisfaction. Three patients in Group C had mild distortion of the implant during pectoral contracture. A meta-analysis of patient satisfaction 6 months and 3 years after TBA is presented.

CONCLUSION

Transaxillary breast augmentation provides consistent, satisfactory results with ease of dissection, when properly indicated. Although the subfascial augmentation mammaplasty has all the advantages of the subpectoral and subglandular augmentation mammaplasties and eliminates the disadvantages of increased postoperative discomfort, implant visibility, and distortion, patients of all three groups had similar rates of satisfaction. Further follow-up is needed in order to compare the long-term effects of the three different planes of insertion.

Subfascial breast implant: a new procedure

Breast augmentation techniques using the submuscular and subglandular planes to introduce the implant are well known and widely used procedures. The authors have been using the subfascial dissection plane, a new concept for breast augmentation. From October of 1998 to September of 2001, 263 patients underwent breast augmentation. In all cases, the implants were inserted into the subfascial plane. McGhan 410 anatomic biodimensional, cohesive gel implants (size, 155 to 310 g) were used. There are additional benefits using this technique; these include avoiding implant deformation or distortion (as seen in the retromuscular position), leaving additional soft tissue between the implant and the skin, and minimizing implant edge prominence (inherent to retroglandular placement). These technical details lead to fewer patient complaints. Morbidity is similar to that of other techniques.

Video microsurgery: evaluation of standard laparoscopic equipment for the practice of microsurgery

Traditional microsurgery involves the use of bulky and expensive stereo microscopes that have limited portability. Recent advances in video technology have enabled the exploration of alternative visualization methods. The purpose of this study was to evaluate standard laparoscopic equipment for microvascular anastomoses. Eight surgeons completed anastomoses on rat femoral and synthetic vessels using stereo microsurgery and video microsurgery visualization systems. All surgeons had previous experience with stereo microsurgery and none had ever used video microsurgery. Data were collected on overall anastomosis and individual suture times. A sample of completed anastomoses was placed in a video database and evaluated by use of a quality rating scale (8 to 10, excellent; 6 to 7, adequate; less than 6, poor). All surgeons subjectively evaluated the video microsurgery system. A total of 48 anastomoses were completed. The average total anastomosis time for the stereo microsurgery was 1018.9 +/- 463.2 seconds versus 1738.9 +/- 460.1 seconds for the video microsurgery. The average individual suture placement time was 114.6 +/- 60.6 seconds for the stereo microsurgery versus 211.7 +/- 128.4 seconds for the video microsurgery (p < 0.05). Twenty-five of the anastomoses underwent quality review. The overall score of the stereo microsurgery group was 8.1 +/- 1.7, and the video microsurgery group had an overall score of 7.3 +/- 1.6. Survey results revealed that 75 percent of the participants thought that the video microsurgery would be useful for human operations and would improve surgeon comfort, but 87.5 percent would not use the present video microsurgery system over stereo microsurgery in their practice. Although significant differences exist in overall anastomosis and individual suture completion times, no difference was found in the overall quality. Video microsurgery could become a useful tool on the basis of surgeon ergonomics; however, optical parameters require further refinement.

Breast augmentation: choosing the optimal incision, implant, and pocket plane

A retrospective study of 220 patients was performed to review surgical design in breast augmentation. Three specific issues were studied: incision site, implant variables, and pocket plane selection. The influence of these three factors on aesthetic results in both primary and secondary cases was the focus of the analysis. No attempt was made to address long-term issues such as capsular contracture or saline implant deflation rates. In 77 primary augmentation patients and 80 unilateral augmentations for symmetry in breast reconstruction, there were the following untoward results: 11 revisions for unilateral malposition, change to a different implant shape, or change to a larger implant size; four deflations of saline implants requiring replacement; and four conversions of saline to silicone gel implants. In 63 secondary cases, there were two hematomas and two infections requiring implant removal and subsequent replacement. Operative technique in breast augmentation is described, as are recommendations for each of the options associated with the three variables studied.
