Efficacy of double mirrored omega pattern for skin sparing mastectomy to reduce ischemic complications

Autoderm in Direct-to-implant Prepectoral Breast Reconstruction Decreases Perioperative Complication Rates and Improves Reconstructive Outcomes

Background

Wise pattern skin incision in breast reconstruction following mastectomy facilitates removal of skin excess in patients with large and ptotic breasts. The trifurcation of the inverted-T incision poses increased risk of infection and reconstructive failure in implant reconstruction. Autoderm has been described in subpectoral implant-based reconstruction. In this case series, it is described in prepectoral implant-based reconstruction.

Methods

A retrospective review of breast cancer patients who underwent either unilateral or bilateral skin-reducing mastectomy via immediate prepectoral implant-based breast reconstruction in conjunction with an inferiorly based autoderm flap for implant coverage between February 2022 to April 2024 was performed and compared with previously published Wise pattern outcomes.

Results

Ten patients (15 breasts) underwent immediate prepectoral implant-based breast reconstruction with an inferiorly-based autoderm flap. Implant sizes ranged from 300 to 800 mL. Autoderm was able to cover the implant under the inverted-T incision in 13 breasts, whereas 1 breast required extension of the dermal flap using acellular dermal matrix. No major complications were observed in this study. One patient developed delayed wound healing in 1 breast that was managed nonoperatively. The test of 2 proportions was used to compare complications to published rates. Rate of delay wound healing showed no significant difference (P = 0.38), whereas the overall complication rate was lower (P < 0.05).

Conclusions

The inferiorly based autoderm flap in immediate prepectoral implant-based breast reconstruction is a safe and effective option in managing patients with large and ptotic breasts that reduces the rate of infection and reconstructive failure.

Wise Versus Vertical Mastopexy Pattern Skin-reducing Mastectomy With Immediate Breast Reconstruction: Systematic Review and Meta-analysis

Background

This study compares postoperative outcomes of Wise and vertical mastopexy pattern skin-reducing/skin-sparing masctomy, hypothesizing that incision choice affects cosmetic outcomes and complication rates.

Methods

A systematic review and meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, searching PubMed, MEDLINE, Embase, Web of Science, and StarPlus Library. Included studies documented skin-sparing mastectomy using Wise or vertical mastopexy patterns with immediate reconstruction. The primary outcome is total mastectomy flap necrosis. The secondary outcomes are major/minor necrosis, infection, hematoma, seroma, and wound complications. Bayesian and frequentist generalized linear mixed models were used for the meta-analysis, including studies with 0 events.

Results

Sixty-six studies were identified, with 39 included in the meta-analysis, comprising 1954 patients and 2311 breast reconstruction cases. The Wise group had a higher rate of mastectomy flap necrosis (14.2%; 95% confidence interval: 10%-20%; I² = 83%) compared with the vertical group (7.8%; 95% confidence interval: 5%-12%; I² = 0%) (P < 0.05). No significant differences were found in other domains. Subgroup analysis favored vertical mastopexy for wound-related complications (P = 0.04).

Conclusions

The Wise pattern shows significantly higher mastectomy flap necrosis than the vertical pattern. However, there were no significant differences in major necrosis, minor necrosis, infection, hematoma, or seroma. Future studies should focus on larger, high-quality randomized controlled trials to better understand the impact of incision techniques on postoperative outcomes.

The Omega Mastopexy Technique for the Correction of Breast Ptosis after Breast Implant Explantation

Background

The past few years have seen a 50% increase in breast implant explantations. Patients with ptotic breasts may desire mastopexy, although conventional techniques are often invasive. We describe our experience with the omega mastopexy technique after breast implant explantation and capsulectomy.

Methods

In the past 2 years, 10 patients with breast Regnault classification ptosis grade I-III underwent the omega mastopexy technique following breast implant explantation and capsulectomy. A detailed description of our operating technique is provided.

Results

This series includes a total of 10 patients. The median age was 48.5 (IQR 42.8-52.5), median body mass index 26 (23.8-28.3) and median implant volume 355 (IQR 325-375). Excellent and stable aesthetic results were achieved without recurring ptosis. One patient, an active smoker, underwent reexcision after 1 year due to hypertrophic scars. No complications have been reported until this date at 2 years follow-up.

Conclusions

The omega mastopexy technique offers an excellent alternative to classic lifting techniques for ptotic breasts after breast implant explantation. Patients with increased risk of wound healing impairment are especially likely to benefit.

Immediate Prepectoral Breast Reconstruction Using an ADM with Smooth Round Implants – A Prospective Observational Cohort Study

Prepectoral breast reconstruction using acellular dermal matrices (ADMs) is well established and used in candidates for nipple/skin-sparing mastectomies; it is based on many different matrices and a great variability in breast implant selection. We describe our experience and clinical outcomes using Braxon® ADMs and smooth round breast implants. Females aged 18-80 years who underwent mastectomies with immediate prepectoral reconstruction between April 2019 and April 2021 were prospectively included. Complications were classified as mastectomy-related (hematoma, necrosis) or reconstruction-related (seroma, infection, red breast syndrome). Binary logistic regression analysis was performed to assess correlation between complication rate and selected variables, which were analyzed per breast with Kruskal-Wallis H test. Fifty-eight patients (102 breasts) received 45 bilateral and 12 unilateral procedures. Drains collected 485.9 cc [range: 100-1260] and were removed 15.7 days [range: 6-29] postoperatively. We report 41 complications (40.2%): 33 mastectomy-related, 8 reconstruction-related. Reoperation occurred in 14 patients: 7 wound debridement and revisions under local anesthesia; and 7 explantation. Implant loss rate was 6.8%. Mastectomy and reconstruction complications were not correlated with any variable. In conclusion, we found prepectoral reconstruction with Braxon® ADMs and smooth round implants to be associated with acceptable complication rates that are not influenced by any patient- or surgery-related factors. Drainage volume is comparable to other breast implant reconstructive techniques, but drains are left in place for longer.

Total breast reconstruction with the fat-augmented latissimus dorsi (FALD) flap: High safety in a single-center uncontrolled case series

According to ASPS, 107,238 breast reconstructions (BR) have been performed in the United States this year. The latissimus dorsi (LD) flap is used for breast reconstruction (BR), either with an implant or an extended flap harvest. Implant-enhanced LD is associated with 50% reoperation rates. To avoid implant-related complications, we introduced the Fat-Augmented LD (FALD) flap. Several authors report 92% patient satisfaction and 36% complication rates (CR). The aim of our study is to present a single-center uncontrolled case series with long follow-up assessing CR and esthetic results. Women with small-to-moderate breasts requiring immediate or delayed BR were included, whereas athletic and paraplegic women or patients with contraindication for free flap BR were excluded. Clinical and surgical data were analyzed. Esthetic analysis was performed using a panel of independent observers. Between December 2010 and November 2019, 100 patients underwent 148 FALD-based BR. Average operative time was 193.5 min for unilateral procedure and 290.6 min for bilateral procedure. Mean immediate AFT volume was 105.3 cc (range 60-170) per breast. Major complication (total or partial flap necrosis > 30%) rate was 0%, and minor complication (partial flap necrosis < 30%, fat necrosis hematoma, seroma, donor site dehiscence, and chronic pain) rate was 6.76%. Esthetic analysis garnered satisfactory results for all types of mastectomies. For variables regarding skin texture (p = 0.001), scar location (p = 0.005), and total score (p = 0.001), patients undergoing Modified Radical Mastectomy scored lower than Skin-Sparing Mastectomy and Nipple-Sparing Mastectomy. We were able to confirm that the FALD flap is a safe with a low complication rate and high patient satisfaction. Level of Evidence IV.

The Bell Pattern: A Novel Breast Incision Approach to Skin-Reducing Mastectomies

Background

As immediate direct to permanent implant-based breast reconstruction (IBBR) continues to gain in popularity, surgeons seek to apply these techniques to patients with large or ptotic breasts. A new bell pattern skin excision is described and limits major complications in this high-risk population.

Objective

The authors describe a novel skin excision pattern for patients with large or ptotic breasts who desire IBBR and assess its safety. The authors also evaluated the ability of the pattern to account for intraoperative developments.

Methods

This retrospective analysis of a single surgeon’s experience included 17 consecutive patients (31 breasts) with large or ptotic breasts undergoing skin-reducing mastectomy with attempted utilization of the bell pattern approach and IBBR with acellular dermal matrix.

Results

Mean age was 50 years, mean body mass index was 27.4 kg/m², and mean breast specimen weight was 683 g. A bell pattern excision was planned for all breasts preoperatively. Three breasts (10%) required an alternative closure pattern due to intraoperative ischemia (n = 1), or additional oncologic resection (n = 2). The pattern successfully accommodated flap ischemia in 8 (26%) other breasts. After a median follow-up of 5.1 months, the number of bell pattern breasts with major and minor complications was 0 (0%) and 9 (32%), respectively. The most common minor complication was seroma (n = 5, 18%), and minor incision wound (n = 3, 11%). There were no reconstruction failures utilizing the bell pattern.

Conclusion

The bell pattern approach is a safe and adaptable alternative to traditional skin-reducing mastectomy in patients with large or ptotic breasts.

Acute and Long-Term Effects of Mechanotherapy on the Outcome After an Achilles Repair: A Prospective Cohort Study With Historical Controls

OBJECTIVES

To evaluate the effects of vibration on Achilles' tendon microcirculation and characteristics following surgical repair of Achilles' tendon rupture.

DESIGN

Cohort study with historical controls.

SETTING

A university institute.

PARTICIPANTS

Participants (N=32), including 19 (16 men, 3 women; median [range] age: 43.0 [25.0-57.0] years) and 13 (10 men, 3 women; 44.00 [29.0-60.0] years) in the vibration (application to the ball of the foot, 30Hz, 2mm amplitude, 4kg pressure, and self-administration) and control groups, respectively, who underwent unilateral Achilles' tendon repairs were recruited.

INTERVENTION

A 4-week vibration intervention in the vibration group.

MAIN OUTCOME MEASUREMENTS

The tendon microcirculation was measured after the first session of vibration. The participants were evaluated repeatedly with bilateral follow-up measurements of tendon stiffness, 3 functional outcome tests, and a questionnaire survey.

RESULTS

Acute effects of the vibration were observed immediately after the 5-minute vibration (P≤.001). Lower total hemoglobin and oxygen saturation were respectively observed (P=.043) in the repaired legs 3 and 6 months postsurgery in the vibration group as compared with the control group. The vibration group also showed greater tendon stiffness, heel raising height and hopping distance 3 or 6 months postoperation in both the repaired and noninjured legs (all P<.05). The microcirculatory characteristics 2 months postoperation were correlated with the outcomes at 6 months postoperation.

CONCLUSIONS

Differences in microcirculatory characteristics and better rehabilitation outcomes were observed in the legs with an Achilles repair that underwent the early vibration intervention.
