The New Method of Pocket Forming for Breast Implant Placement in Augmentation Mammaplasty: Dual Plane Subfascial

The Reverse Dual Plane: A Novel Technique for Endoscopic Transaxillary Breast Augmentation

Background

Quite a few Asian patients prefer axillary incision for breast augmentation. However, this surgery needs improvement.

Objectives

To introduce a reverse dual-plane technique through a transaxillary approach and compare it with a transaxillary dual-plane approach.

Methods

Eighty-two patients were divided into Group A (n = 40) and Group B (n = 42). Axillary incision and endoscope were utilized in the 2 groups. Tebbetts' dual plane was performed in Group A patients. Patients in Group B underwent our reverse dual-plane technique, in which the upper 70% was subfascial and the lower 30% was subpectoral, with the fascia of the external oblique and anterior serratus being elevated together with the pectoral muscle. The Numeric Pain Rating Scale (NPRS) scores were recorded daily for 7 days. Breast shape and softness, in both sitting and supine positions, were assessed by the patients, and complications were compared.

Results

The NPRS scores of Group B patients were significantly lower than those of Group A patients (P < .01). The satisfaction rate of shape and softness in the seated position was not significantly different (P > .05). However, in the supine position, only 20 patients (50.0%) in Group A and 32 patients (76.2%) in Group B were satisfied with their breast softness (P < .01), and the breasts of the others became stiffer. Breast animation deformity (BAD) occurred in 2 patients in Group A and in no patient in Group B (P < .01). Other complications were not significantly different.

Conclusions

Compared with Tebbetts' dual plane, this procedure significantly reduced pain, improved breast softness, and eliminated BAD, without increasing complications.

Multiplanar (4-Dimension) Breast Augmentation-A Personal Surgical Concept for Dynamic Implant-Tissue Interaction Providing Sustainable Shape Stability

BACKGROUND

In esthetic breast augmentation long-term shape stability and natural appearance remain an ongoing challenge. The authors found that to reduce the incidence of secondary deformity and increase the natural feel and appearance, a standard multiplanar procedure combining a subfascial and dual plane approach with fasciotomies will provide long-term stability and esthetic quality.

PATIENTS AND METHODS

The technique involves a submuscular dissection, release of the infranipple portion of the pectoralis muscle combined with the wide subfascial release of the breast gland, and scoring of the deep plane of the superficial glandular fascia. For long-term stability, a firm fixation of the glandular fascia at the inframammary fold to the deep layer of the abdomino-pectoral fascia is critical. Long-term results were analyzed for up to 10 years.

RESULTS

Postoperative measurements proved the intrinsic balance of the breasts without significant changes over time. The overall complication rate was <5%. Shape stability was observed over 10 years in more than 95% of the patients. Unsightly muscular animation could be avoided in almost every patient.

CONCLUSIONS

Our results indicate that a technique of multiplane breast augmentation provides long-term stability and esthetic quality. By combining the benefits of well-established techniques of a submuscular dual plane, additional shaping through a controlled deep fasciotomy and stable inframammary fold fixation some of the existing tradeoffs of the different methods can be avoided.

The Key of Pocket Dissection in Transaxillary Dual-plane Breast Augmentation: How to Control Inferior Malposition of Smooth Implants

BACKGROUND

Inferior implant malposition after breast augmentation is the second most common reason for revision surgery. This article introduces the new concept of dual-plane pocket formation in transaxillary breast augmentation to prevent inferior implant malposition by preserving the continuity of the superficial layer of the deep pectoralis fascia.

METHODS

Patients who underwent transaxillary endoscopic breast augmentation performed from January 2017 to December 2019 were retrospectively reviewed. With the aid of the endoscope, dissection proceeded. During pectoralis muscle origin detachment, the superficial layer of deep pectoralis fascia was preserved. After making the pocket, silicone gel implants were inserted. A retrospective chart review was done to collect data on postoperative complications.

RESULTS

A total of 251 patients were performed, and the mean follow-up time was 20.6 months. In a total of 28 cases of complications (9.6%), there were 2 cases of reoperations. In a total of three patients (1.2%) of implant malposition, one patient (0.4%) developed mild bilateral bottoming-out deformity.

CONCLUSIONS

Meticulous dissection by endoscopy could avoid the destruction of the superficial layer of the deep pectoralis fascia during pocket dissection and produce an intact fascial system with its own continuity at the inframammary fold (IMF). A well-controlled envelope over the implant and a supporting structure underneath it are important in breast augmentation to prevent inferior implant malposition.

Trends in Breast Augmentation Research: A Bibliometric Analysis

BACKGROUND

Breast augmentation is one of the most demanded procedures in plastic surgery and one of the most commonly performed by plastic surgeons. However, a bibliometric analysis of breast augmentation has not been published in recent years. The current study aimed to use a bibliometric analysis to conduct a qualitative and quantitative evaluation of breast augmentation research and provide the research trends and hotspots in this field.

METHODS

Publications on breast augmentation research were extracted from the Web of Science core collection database. VOSviewer 1.6.18 was used to assess co-authorship, co-occurrence, citation of countries, institutions, authors, and journals, as well as hotspot keywords.

RESULTS

On February 8, 2022, 4637 records of breast augmentation research published from 1985 to 2021 were collected. The bulk of the retrieved studies were original research articles (n = 2235, 48.20%). A total of 1053 (22.71%) papers were open access. The annual publication output increased annually. The USA was the driving force in this field and had a strong academic reputation. The top-contributing institution was the University of Texas MD Anderson Cancer Center (2.37%, with 110 publications). Plastic and reconstructive surgery (998 publications, 21.52%) published the most research in this field and was also the most frequently co-cited journal (22,351 citations, total link strength (TLS): 409,301). Clemens MW (68 publications, 1.47%) was the most prolific author, and Spear SL (1456 citations, TLS: 27,231) was the most frequently co-cited author. The research hotspots included the following four aspects: safety and effectiveness of breast implants, implant-based breast reconstruction, breast cancer incidence after breast implantation, and breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL). The research trends were BIA-ALCL, implant-based breast reconstruction, BREAST-Q, acellular dermal matrix, capsular contracture, and autologous fat grafting.

CONCLUSION

The present study provides a panoramic view of breast augmentation research in plastic and reconstructive surgery. This novel comprehensive bibliometric analysis can help researchers and nonresearchers alike to rapidly identify the potential partners, research hotspots, and research trends within their areas of interest.

Implant-based multiplane breast augmentation—a personal surgical concept for dynamic implant–tissue interaction providing sustainable shape stability

Background

The aesthetic long-term stability in shape, symmetry, and natural appearance of an aesthetically augmented breast remains a constant challenge. It has become clear that the results depend strongly on the technique applied and the experience of the surgeon. An ongoing controversy concerns the positioning of the implants. Subglandular, submuscular, partial submuscular, and subfascial pockets have different tradeoffs and advantages. However, secondary deformity, unnatural feel, and appearance are not addressed uniformly. The aim of the following study was to establish a standard procedure allowing for the desired and reproducible results to provide long-term stability and aesthetic quality.

Methods

The authors have developed a standardized dissection of a dynamic implant pocket. In this approach, a submuscular dissection with lower and medial release of the pectoralis muscle is combined with a wide subfascial release of the breast gland and a scoring of the deep plane of the superficial glandular fascia. In the final step, the deep layer of the glandular fascia is sutured tightly and firmly to the deep layer of the abdomino-pectoral fascia. A total of 867 patients received a 4D pocket–based breast implant by the authors. A subset of 33 patients was further analyzed for long-term results. Retrospectively, all data were analyzed from the electronic patient information system and files of patients using GraphPad 8. For comparison of multiple experimental groups, one-way ANOVA was performed where indicated.

Results

The concept not only addresses the biplanar approach of submuscular implant placement (3D) but adds the 4th dimension (4D) of an aesthetically pleasing dynamic shape of the augmented breast providing long-term stability. Measurements—taken at 3 months, and 1, 2, 3, 5, and ≥ 7 years post augmentation—for SN-N, N-IMF, N-ML, and MC-N distances did not show any significant changes over time. In the patient cohort of 867 patients (1734 implants), the overall complication rate was < 5%. Revisions for bleeding were below 0.5%. Shape stability was observed over 7 years in more than 95% of the patients.

Conclusions

Our results indicate that our technique of multiplane breast augmentation provides long-term stability and aesthetic quality. It may solve some of the existing tradeoffs of the different methods by combining the benefits of each technique supported by an additional shaping through a controlled deep fasciotomy.

The Nomenclature, Terminology and Lexicon of Breast Surgery: Are We Really Saying the Same Thing?

This study investigated inconsistencies in the use of descriptors in breast surgery and recommends a novel nomenclature that will be adopted and standardized among plastic surgeons. The study used a modified Delphi methodology to first identify redundant descriptors or those with multiple interpretations, and then achieve consensus on ideal recommended nomenclature in breast surgery. The Delphi panel agreed that there was misuse of and lack of a clear definition for several terms, and recommended removal of these subjective terms. Replacement with more anatomic nomenclature was suggested. Stretch deformity, pectoral banding, and implant-gland mismatch were introduced as new terms.
