Isolated and combined breast augmentation in transgender patients: Multi-institutional insights into early outcomes and risk factors.

BACKGROUND: The increasing demand for gender-affirming surgery (GAS) in transgender and gender-diverse healthcare highlights the importance of breast augmentation surgery (BAS) for transfeminine patients. Despite its significance, there is a lack of research on postoperative outcomes of BAS. METHODS: We analyzed the multi-institutional American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) (2008-2021) database to identify female transgender individuals (TGIs) who underwent BAS surgery, both isolated and combined with concurrent GAS procedures. We evaluated 30-day outcomes, including the incidence of mortality, reoperation, readmission as well as surgical and medical complication occurrence. RESULTS: Of 1699 female TGIs, 92% underwent isolated BAS and 7.7% underwent combined BAS. The mean age and body mass index (BMI) were 36 ± 12 years and 27 ± 6.6 kg/m2, respectively. Isolated BAS showed a 2.8% complication rate, while combined BAS had a higher rate with 9.1%. Specifically, all complications occurred in patients undergoing BAS with concurrent genitourinary surgery (n = 85; 14%), whereas no adverse events were recorded after combined BAS and facial feminization (n = 19) or chondrolaryngoplasty (n = 19). In patients seeking combined BAS, advanced age (p = 0.05) and nicotine abuse (p = 0.004) were identified as risk factors predisposing to adverse events, whereas American Society of Anesthesiology class 1 was found to be protective (p = 0.02). CONCLUSIONS: Isolated BAS in TGIs demonstrates a positive safety profile. Combined surgeries, particularly with genitourinary procedures, pose higher risks. Identifying risk factors such as smoking and advanced age is crucial for patient selection and surgical planning. These findings can aid in refining patient eligibility and inform surgical decision-making for BAS.

A Ready-to-Use Grading Tool for Facial Palsy Examiners-Automated Grading System in Facial Palsy Patients Made Easy.

BACKGROUND: The grading process in facial palsy (FP) patients is crucial for time- and cost-effective therapy decision-making. The House-Brackmann scale (HBS) represents the most commonly used classification system in FP diagnostics. This study investigated the benefits of linking machine learning (ML) techniques with the HBS. METHODS: Image datasets of 51 patients seen at the Department of Plastic, Hand, and Reconstructive Surgery at the University Hospital Regensburg, Germany, between June 2020 and May 2021, were used to build the neural network. A total of nine facial poses per patient were used to automatically determine the HBS. RESULTS: The algorithm had an accuracy of 98%. The algorithm processed the real patient image series (i.e., nine images per patient) in 112 ms. For optimized accuracy, we found 30 training runs to be the most effective training length. CONCLUSION: We have developed an easy-to-use, time- and cost-efficient algorithm that provides highly accurate automated grading of FP patient images. In combination with our application, the algorithm may facilitate the FP surgeon's clinical workflow.

Effect of Radiation Therapy on Microsurgical Deep Inferior Epigastric Perforator Flap Breast Reconstructions: A Matched Cohort Analysis of 4577 Cases.

INTRODUCTION: Breast reconstruction with autologous tissue is a state-of-the art procedure. Several patient-related factors have been identified with regard to the safety and efficacy of these reconstructions. The presented study investigates the impact of prereconstruction radiation on outcomes of deep inferior epigastric perforator (DIEP) free-flap breast reconstructions using largest database available in Europe. MATERIALS AND METHODS: Between 2011 and 2019, 3926 female patients underwent 4577 DIEP flap breast reconstructions in 22 different German breast cancer centers. The cases were divided into a no-radiation (NR) and a radiation (R) group, according to radiation status before reconstruction. Groups were compared with regard to surgical complications and free-flap outcome. RESULTS: Overall, there was no significant difference between the groups regarding the rate of total flap loss [1.9% (NR) vs 2.1% (R), P = 0.743], partial flap loss [0.9% (NR) vs 1.5 (R), P = 0.069], and revision surgery [vascular revision: 4.4% (NR) vs 4.1% (R), P = 0.686; wound revision: 7.6% (NR) vs 9.4% (R), P = 0.122]. However, the patients had a significantly higher risk of developing wound healing disturbances at the recipient site [1.2% (NR) vs 2.1% (R), P = 0.035] and showed significantly longer hospitalization {8 [SD, 8.4 (NR)] vs 9 [SD, 15.4 {R}] days, P = 0.006} after prereconstruction radiation. CONCLUSIONS: Our findings suggest that DIEP flap reconstruction after radiation therapy is feasible. Women with a history of radiation therapy should, however, be informed in detail about the higher risk for wound healing disturbances at the recipient site.

Clinical Case of Acute Non-Traumatic Hand Compartment Syndrome and Systematic Review for the Upper Extremity.

Background: While trauma to the upper extremity is known to cause acute compartment syndrome (ACS), nontraumatic causes of ACS of the upper extremity are rare. Nontraumatic ACS of the upper extremity can lead to adverse outcomes if not recognized early. There are limited reports of spontaneous ACS published in the literature. The aim of this comprehensive systematic review is to increase awareness among plastic surgeons and hand surgeons of this acute event and provide an algorithmic approach to management in the acute setting through an illustrative case example. Methods: A comprehensive systematic review of published literature was conducted in the Medline/PubMed database with the search terms, "compartment syndrome," "extremity," "spontaneous," "nontraumatic," and "atraumatic" without timeframe limitations. Articles were identified and included in this review based on ACS localization in the upper extremity and etiology of nontraumatic, spontaneous origin. Results: Sixteen publications and 19 total cases of nontraumatic ACS of the upper extremity from 1993 to 2016 met our search criteria. A bleeding disorder was the etiology in three cases, systemic anticoagulation in three cases, infection in six cases, and unknown in three cases. The remaining four cases included systemic sclerosis, Ehlers-Danlos syndrome, rhabdomyolysis, and McArdle disease. Conclusions: Nontraumatic causes of ACS of the upper extremity include infection, anticoagulation therapy, and bleeding disorders. Even though trauma is the most common cause of ACS, clinicians should be aware of these other potential causes of ACS in the nontraumatic setting. Appropriate medical and surgical intervention should be done to avoid potential adverse outcomes.

Impact of Intraoperative Hypothermia on Microsurgical Free Flap Reconstructions.

BACKGROUND: Patients requiring microsurgical defect reconstruction are highly susceptible to intraoperative hypothermia, given oftentimes long operative times and exposure of large skin surface areas. While the impact of hypothermia has been extensively studied across various surgical fields, its role in the setting of microsurgical free flap reconstruction remains elusive. This study evaluates the effects of hypothermia on outcomes of free flap reconstructions. METHODS: Within 7 years, 602 patients underwent 668 microvascular free flap reconstructions. The cases were divided into two groups regarding the minimal core body temperature during free flap surgery: hypothermia (HT; < 36.0°C) versus normothermia (NT; ≥36.0°C). The data were retrospectively screened for patients' demographics, perioperative details, flap survival, surgical complications, and outcomes. RESULTS: Our data revealed no significant difference with regard to the rate of major and minor surgical complications, or the rate of revision surgery between both groups (p > 0.05). However, patients in the HT group showed significantly higher rates of total flap loss (6.6% [HT] vs. 3.0% [NT], p < 0.05) and arterial thrombosis (4.6% [HT] vs. 1.9% [NT], p < 0.05). This translated into a significantly longer hospitalization of patients with reduced core body temperature (HT: mean 16.8 days vs. NT: mean 15.1 days; p < 0.05). CONCLUSION: Hypothermia increases the risk for arterial thrombosis and total flap loss. While free flap transfer is feasible also in hypothermic patients, surgeons' awareness of core body temperature should increase. Taken together, we suggest that the mean intraoperative minimum temperature should range between 36 and 36.5°C during free flap surgery as a pragmatic guideline.

Pediatric ulnar artery pseudoaneurysm of the wrist after glass laceration: A case report and systematic review of the literature.

BACKGROUND: Our purpose was to explore a case of a complicated ulnar artery pseudoaneurysm and propose an algorithm to guide physicians in this scenario. We present a case of a 5-year-old boy with a pediatric ulnar artery pseudoaneurysm that developed after a wrist laceration from broken glass 6 weeks after the initial injury. The diagnosis of pseudoaneurysm was missed, and the patient was transferred to our facility in urgent need of resection and repair due to profuse bleeding. An ultrasound confirmed the suspected diagnosis of ulnar artery aneurysm with thrombosis within the vessel. An area of skin necrosis was also present. Upon exploration of the wound, the ulnar artery pseudoaneurysm was identified and resected. The defect measured six millimeters and it was repaired primarily, under the microscope, after the proximal and distal portions were freed by dissection. The patient's incision was well healed at six-week follow-up. METHOD: A systematic literature review of the English literature on ulnar artery aneurysm was conducted on PubMed/Medline, Embase, Cochrane Clinical Answers, and Cochrane Clinical Trials, without timeframe limitations. Finally, we provide an algorithm to assist the decision-making process in similar scenarios. CONCLUSION: Although ulnar artery aneurysm is rare on a pediatric patient, it should be considered in the differential diagnosis each time a patient presents with a wrist mass. In such cases, a high index of suspicion warrants examination by a hand specialist.

Comparison of Outcomes of End-to-End versus End-to-Side Anastomoses in Lower Extremity Free Flap Reconstructions.

BACKGROUND: Whether to perform an end-to-end (ETE) versus end-to-side (ETS) arterial anastomosis is an integral part of preoperative planning and intraoperative decision making in free flap-based reconstructions. This study evaluated the impact of microsurgical anastomotic technique on outcomes of lower extremity reconstructions, with a focus on patients with peripheral arterial disease (PAD). METHODS: Over a 6-year period, 425 patients underwent 437 microvascular lower extremity free flap reconstructions with fasciocutaneous anterolateral thigh- or gracilis muscle flaps at a single surgical center. The cases were divided into an ETE (n = 297 patients) versus ETS (n = 128 patients) group according to the anastomotic technique. A retrospective analysis of patients' demographics, perioperative details, surgical complications, free flap types, recipient sites, flap survival, and the potential impact of PAD on outcomes was performed. Patient groups were comparable regarding comorbidities, American Society of Anesthesiologists scores, types of performed free flaps and recipient sites. RESULTS: We found no significant differences between the ETE versus ETS groups regarding the rate of major or minor complications (p > 0.05). Specifically, in patients suffering from PAD (n = 64) the type of arterial anastomosis had no effect on the outcome. CONCLUSION: Overall, no significant differences in outcomes were observed when comparing the types of performed arterial anastomosis. This observation also held true for the subgroup of patients with PAD. Given that an ETS anastomosis did not increase the risk to encounter complications while preserving distal perfusion, we believe that this technique is the method of choice, especially in patients with impaired vascular status.

Primary Hand Leiomyoma: A Systematic Review.

BACKGROUND: Primary leiomyoma is a rare cause of a mass in the hand, with few reported cases to date. To our knowledge, this constitutes the most comprehensive and up-to-date systematic review of the literature of all cases of primary hand leiomyoma. We also provide an additional case recently managed in our practice of confirmed primary vascular leiomyoma of the hand in a 44-year-old woman to add to the current body of literature. METHODS: We performed a comprehensive literature review of all articles published on primary leiomyoma of the hand. The PubMed database was used, with search terms leiomyoma hand, angioleiomyoma hand, and angiomyoma hand. Articles were selected for their accuracy in anatomic localization in the hand and confirmed pathology of leiomyoma. RESULTS: Our initial search query resulted in 216 articles. After applying the inclusion criteria, we identified 50 individual articles with 108 cases of confirmed primary leiomyoma in the hand from January 1, 1954, to July 1, 2018. Common initial clinical impressions recorded for primary hand leiomyoma included ganglion cyst, giant-cell tumor, hemangioma, and glomus tumor. Patients presenting with leiomyoma of the hand frequently describe a painful lesion, which differs from most other benign tumors of the hand at presentation. CONCLUSIONS: Leiomyoma is an important consideration when developing a differential diagnosis for primary benign masses in the hand. We hope that this comprehensive review can provide increased awareness of this tumor type.

Postmastectomy Radiation Therapy (PMRT) before and after 2-Stage Expander-Implant Breast Reconstruction: A Systematic Review.

Background: In those undergoing treatment for breast cancer, evidence has demonstrated a significant improvement in survival, and a reduction in the risk of local recurrence in patients who undergo postmastectomy radiation therapy (PMRT). There is uncertainty about the optimal timing of PMRT, whether it should be before or after tissue expander or permanent implant placement. This study aimed to summarize the data reported in the literature on the effect of the timing of PMRT, both preceding and following 2-stage expander-implant breast reconstruction (IBR), and to statistically analyze the impact of timing on infection rates and the need for explantation. Methods: A comprehensive systematic review of the literature was conducted using the PubMed/Medline, Ovid, and Cochrane databases without timeframe limitations. Articles included in the analysis were those reporting outcomes data of PMRT in IBR published from 2009 to 2017. Chi-square statistical analysis was performed to compare infection and explantation rates between the two subgroups at p < 0.05. Results: A total of 11 studies met the inclusion criteria for this study. These studies reported outcomes data for 1565 total 2-stage expander-IBR procedures, where PMRT was used (1145 before, and 420 after, implant placement). There was a statistically significant higher likelihood of infection following pre-implant placement PMRT (21.03%, p = 0.000079), compared to PMRT after implant placement (9.69%). There was no difference in the rate of explantation between pre-implant placement PMRT (12.93%) and postimplant placement PMRT (11.43%). Conclusion: This study suggests that patients receiving PMRT before implant placement in 2-stage expander-implant based reconstruction may have a higher risk of developing an infection.

The spreaded gracilis flap revisited: Comparing outcomes in lower limb reconstruction.

BACKGROUND: In lower limb reconstruction, the free gracilis muscle flap is usually chosen for coverage of small- to medium-sized defects. Aim of this study was a re-appraisal regarding the reconstructive indications of the gracilis muscle flap with a focus on postoperative complications in order to evaluate if it can also be routinely used to reconstruct large-size lower limb defects. METHODS: A total of 204 patients underwent free gracilis muscle transfers for lower limb reconstruction at our institution. Cases were divided according to the size of the defect into two groups (<150 cm2 versus ≥150 cm2 ). The small- to medium defect size group included 150 patients and the large defect size group included 54 patients. In the large defect size group, the muscle was enlarged as needed by careful dissection of the epimysium and all connective tissue surrounding the intrinsic vessels under loupe magnification to protect the muscle perfusion. Surgical complications were accounted for and the two groups compared accordingly. RESULTS: Overall, there were no significant differences between the two groups of patients regarding the rate of major (15.72% versus 10.91%; P = .506) and minor surgical complications (6.92% versus 3.64%; P = .522). The total percentage of flap losses in the small to medium defect size group was 5.03%. There were no total flap losses in the large defect size group (P = .117). CONCLUSION: The use of the spreaded gracilis flap provides a valuable option for the microsurgeon, especially also to reconstruct large size lower limb defects.

Postburn Head and Neck Reconstruction: An Algorithmic Approach.

BACKGROUND: Optimizing functional and aesthetic outcomes in postburn head and neck reconstruction remains a surgical challenge. Recurrent contractures, impaired range of motion, and disfigurement because of disruption of the aesthetic subunits of the face, can result in poor patient satisfaction and ultimately, contribute to social isolation of the patient. In an effort to improve the quality of life of these patients, this study evaluates different surgical approaches with an emphasis on tissue expansion of free and regional flaps. METHODS: Regional and free-flap reconstruction was performed in 20 patients (26 flaps) with severe postburn head and neck contractures. To minimize donor site morbidity and obtain large amounts of thin and pliable tissue, pre-expansion was performed in all patients treated with locoregional flap reconstructions (12/12), and 62% (8/14) of patients with free-flap reconstructions. Algorithms regarding pre- and intraoperative decision-making are discussed, and complications between the techniques as well as long-term (mean follow-up 3 years) results are analyzed. RESULTS: Complications, including tissue expander infection with need for removal or exchange, partial or full flap loss, were evaluated and occurred in 25% (3/12) of patients with locoregional and 36% (5/14) of patients receiving free-flap reconstructions. Secondary revision surgery was performed in 33% (4/12) of locoregional flaps and 93% (13/14) of free flaps. CONCLUSIONS: Both locoregional as well as distant tissue transfers have their role in postburn head and neck reconstruction, whereas pre-expansion remains an invaluable tool. Paying attention to the presented principles and keeping the importance of aesthetic facial subunits in mind, range of motion, aesthetics, and patient satisfaction were improved long term in all our patients, while minimizing donor site morbidity.

The hybrid approach for reconstruction of severely destructed lower eyelids: combination of skin grafting, temporary tarsorrhaphy, and autologous fat grafting for cicatricial ectropion after injection of commercial grade silicone.

BACKGROUND: Although silicone injections for permanent soft tissue augmentation were popular in the past, their use has become unduly controversial because of severe complications, mainly caused by injection of illegal silicones by unlicensed practitioners. The delicate local anatomy of the lower eyelid region makes this region particularly susceptible for complications after silicone augmentation including local inflammation, tissue retraction, and consecutive cicatricial ectropion leading to lagophthalmus and ocular surface irritation. CLINICAL REPORT: This is a case of a 47-year-old patient demonstrating severe lower eyelid destruction with consecutive ectropion after injection of commercial grade silicone in Thailand 5 years prior, leading to chronic granulomatous infections requiring multiple surgical interventions.Our hybrid approach included radical debridement with complete elimination of silicone residues, lateral canthopexy, reconstruction of the entire lower eyelid esthetic unit using a supraclavicular full-thickness skin graft, and temporary tarsorrhaphy followed by 2 sessions of autologous fat graft injections.Although many previous publications mainly focus on individual aspects of lower eyelid reconstruction, we describe a staged reconstructive approach for correction of severely destructed lower eyelid defects with consecutive lower eyelid ectropion. CONCLUSIONS: The hybrid approach presented here has proven to be a viable surgical strategy for lower eyelid reconstruction, with esthetically appealing results.

Aesthetic breast shape preferences among plastic surgeons.

BACKGROUND: There has been little discussion in the plastic surgery literature regarding breast shape preferences among plastic surgeons, despite strong evidence that such aesthetic preferences are influenced by multiple factors. Much effort has been focused on delineating the objective criteria by which an "attractive" breast might be defined. This study aimed at providing a better understanding of the presence and significance of differences in personal aesthetic perception, and how these relate to a plastic surgeon's demographic, ethnic, and cultural background, as well as practice type (academic vs private). METHODS: An interactive online survey was designed. Modifiable ranges of upper pole fullness and areola size were achieved via digital alteration, enabling participants to interactively change the shape of a model's breasts. The questionnaire was translated into multiple languages and sent to plastic surgeons worldwide. Demographic data were also collected. Analysis of variance was used to elucidate plastic surgeon's breast shape preferences in respect to sex and age, geographic and ethnic background, as well as practice type. RESULTS: The authors gathered 614 responses from 29 different countries. Significant differences regarding preferences for upper pole fullness, areola size in the natural breast, and areola size in the augmented breast were identified across surgeons from the different countries. Further, significant relationships regarding breast shape preferences were distilled between the age and sex of the surgeon, as well as the practice type. No differences were found in respect to the surgeons' self-reported ethnic background. CONCLUSIONS: Country of residence, age, and practice type significantly impact breast shape preferences of plastic surgeons. These findings have implications for both patients seeking and surgeons performing cosmetic and reconstructive breast surgery. In an increasingly global environment, cultural differences and international variability must be considered when defining and publishing new techniques and aesthetic outcomes. When both the plastic surgeon and the patient are able to adequately and effectively communicate their preferences regarding the shape and relations of the breast, they will be more successful at achieving satisfying results.

The impact of geographic, ethnic, and demographic dynamics on the perception of beauty.

BACKGROUND: Beauty lies in the eyes of the beholder, but influenced by the individual's geographic, ethnic, and demographic background and characteristics. In plastic surgery, objective measurements are used as a foundation for aesthetic evaluations. This study assumes interdependence between variables such as country of residence, sex, age, occupation, and aesthetic perception. METHODS: Computerized images of a model's face were generated with the ability to alter nasal characteristics and the projection of the lips and chin. A survey containing these modifiable images was sent to more than 13,000 plastic surgeons and laypeople in 50 different countries, who were able to virtually create a face that they felt to be the aesthetically "ideal" and most pleasing. Demographic information about the interviewees was obtained. RESULTS: Values of various aesthetic parameters of the nose were described along with their relationship to geography, demography, and occupation of the respondents. Interregional and ethnic comparison revealed that variables of country of residence, ethnicity, occupation (general public vs surgeon), and sex correlate along a 3-way dimension with the ideal projection of the lips and the chin. Significant interaction effects were found between variables of country of residence or ethnicity with occupation and sex of the respondents. CONCLUSIONS: What are considered the "ideal" aesthetics of the face are highly dependent on the individual's cultural and ethnic background and cannot simply and solely be defined by numeric values and divine proportions. As confirmed with this study, ethnic, demographic, and occupational factors impact peoples' perception of beauty significantly.

The role of autologous fat grafting in secondary microsurgical breast reconstruction.

BACKGROUND: Autologous breast reconstruction offers higher rates of patient satisfaction, but not all patients are ideal candidates, often due to inadequate volume of donor sites. Although autologous fat grafting is frequently used to augment volume and contour abnormalities in implant-based breast reconstruction, its clear utility in microsurgical breast reconstruction has yet to be defined. Here, we examined patients undergoing autologous microsurgical breast reconstruction with and without the adjunct of autologous fat grafting to clearly define utility and indications for use. METHODS: A retrospective review of all patients undergoing autologous breast reconstruction with microvascular free flaps at a single institution between November 2007 and October 2011 was conducted. Patients were divided into 2 groups as follows: those requiring postoperative fat grafting and those not requiring fat grafting. Patient demographics, indications for surgery, history of radiation therapy, patient body mass index, mastectomy specimen weight, need for rib resection, flap weight, and complications were analyzed in comparison. RESULTS: Two hundred twenty-eight patients underwent 374 microvascular free flaps for breast reconstruction. One hundred (26.7%) reconstructed breasts underwent postoperative fat grafting, with an average of 1.12 operative sessions. Fat was most commonly injected in the medial and superior medial poles of the breast and the average volume injected was 147.8 mL per breast (22-564 mL). The average ratio of fat injected to initial flap weight was 0.59 (0.07-1.39). Patients undergoing fat grafting were more likely to have had deep inferior epigastric perforator and profunda artery perforator flaps as compared to muscle-sparing transverse rectus abdominis myocutaneous. Patients additionally were more likely to have a prophylactic indication 58% (n = 58) versus 42% (n = 117) (P = 0.0087), rib resection 68% (n = 68) versus 54% (n = 148) (P < 0.0153), and acute postoperative complications requiring operative intervention 7% (n = 7) versus 2.1% (n = 8) (P < 0.0480). Additionally, patients undergoing autologous fat grafting had smaller body mass index, mastectomy weight, and flap weight. CONCLUSIONS: Fat grafting is most commonly used in those breasts with rib harvest, deep inferior epigastric perforator flap reconstructions, and those with acute postoperative complications. It should be considered a powerful adjunct to improve aesthetic outcomes in volume-deficient autologous breast reconstructions and additionally optimize contour in volume-adequate breast reconstructions.

A novel approach to frontal sinus surgery: treatment algorithm revisited.

BACKGROUND: Access to the frontal sinus remains a challenging problem for the craniofacial surgeon. A wide array of techniques including minimally invasive endoscopic approaches have been described. Here we present our technique using medical modeling to gain fast and safe access for multiple indications. METHODS: Computer-aided surgery involves several distinct phases: planning, modeling, surgery, and evaluation. Computer-aided, precise cutting guides are designed preoperatively and allowed to perfectly outline and then cut the anterior table of the frontal sinus at its junction to the surrounding frontal bone. The outcomes are evaluated by postoperative three-dimensional computed tomography scan. RESULTS: Eight patients sustaining frontal sinus fractures were treated with the aid of medical modeling. Three patients (37.5%) had isolated anterior table fractures, and 4 (50%) had combined anterior and posterior table fractures, whereas 1 patient (12.5%) sustained isolated posterior table fractures. Operative times were significantly shorter using the cutting guides, and fracture reduction was more precise. There was no statistically significant difference in complication rates or overall patient satisfaction. CONCLUSIONS: The surgical approach to the frontal sinus can be made more efficient, safe, and precise when using computer-aided medical modeling to create customized cutting guides.
