Deep Subcutaneous Gluteal Fat Compartments: Anatomy and Clinical Implications.

BACKGROUND: Advances in gluteal fat grafting have resulted in diminished risks through improved understanding of regional anatomy and technical nuances. No anatomic studies identifying the presence or absence of buttock fat compartments have yet been reported. OBJECTIVES: The aim of this cadaveric study was to identify and characterize the deep subcutaneous gluteal fat compartments to further understand the nuanced differences between deep and superficial subcutaneous fat layers. METHODS: A cadaveric study was performed to identify the fat compartments. Latex injection into the iliac artery and vein was used to prepare 4 fresh (N = 8 hemibuttocks) hydrated cadavers for dissection. Preliminary work identified the likely position of deep gluteal fat compartments. The cannula was positioned under ultrasound guidance in between the superficial and deep gluteal layers. Cadaveric buttocks were infiltrated by the static technique with dyed human fat, dyed applesauce, and dyed saline in an attempt to identify the gluteal deep subcutaneous fat compartments. RESULTS: Dissection identified and characterized 7 discrete deep gluteal fat compartments. These comprise 3 medial fat compartments (superior, middle, and inferior); a central fat compartment; and 3 lateral (superior, middle, and inferior) deep fat compartments. CONCLUSIONS: Seven deep gluteal fat compartments have been identified that have distinct boundaries and maintain injected contents separate from each other above the gluteal muscle fascia. These compartments can be selectively expanded for buttock augmentation. Knowledge of these compartments enables surgeons to perform gluteal augmentation by static infiltration, injecting autologous fat under ultrasound guidance in the deep subcutaneous fat layer, while optimizing aesthetic considerations.

Functional Thenar Reconstruction: A Case Report and Systematic Review of the Literature.

ABSTRACT: Reconstruction of the thumb is among the most complex challenges faced by hand surgeons. Meaningful functional recovery of the thumb is dependent mainly on thumb opposition and palmar abduction. Free functional muscle transfer provides neurotized, robust soft tissue coverage that can achieve dynamic reconstruction of thenar musculature in a single stage.We present a case of a free neurotized segmental gracilis muscle transfer for thenar reconstruction and a systematic review of thenar reconstruction with free functional muscle transfer in the literature. A teenage male patient with a gunshot-induced thenar defect was reconstructed using a free neurotized gracilis muscle measuring 5 × 11 cm. The obturator nerve was coapted to the recurrent motor branch of the median nerve. The patient reached M4 strength at 10 months with functional use of his thumb. A systematic review of options for functional thenar reconstruction revealed 14 studies describing functional thenar reconstruction in 44 patients. Successful functional flaps described included gracilis muscle, pronator quadratus muscle, pectoralis minor muscle, abductor hallucis muscle, extensor digitorum brevis muscle, and serratus anterior muscle. Microsurgical transfer of a functional muscle is an excellent option for single-stage thenar reconstruction of both form and function. There are a number of available donor sites with equivalent size and bulk to that of native thenar musculature.

Compression Screw Fixation of Lunate Fracture: Case Report and Review of the Literature.

Background Isolated traumatic lunate fractures without other surgical carpal bone or ligamentous injuries are extremely rare, with few published reports available to guide management. Lunate fracture management is controversial, and depends on concurrent injuries of adjacent carpal bones, ligaments, risk of ischemia, and displacement. Case Description A 48-year-old right hand dominant man suffered a crush injury to the left hand caught between a forklift and a metal shelf. Radiographs and computed tomography imaging of the left hand and wrist were significant for a displaced Teisen IV fracture of the lunate. A dorsal ligament sparing approach was utilized to access, reduce, and fixate the fracture using a headless compression screw. After immobilization and rehab, at 9 months after initial injury, the patient was back to work on full duty without restriction and pleased with the results of his treatment. Literature Review A literature review of lunate fracture compression screw fixation was performed and revealed a total of three reports indicating successful treatment of fractures, with patients returning to full activity. Clinical Relevance Lunate fractures are rare, often missed, and treating these injuries can be challenging, particularly in the setting of acute trauma. Based on our limited experience, we believe that open reduction and internal fixation of isolated Teisen IV lunate fractures with a headless compression screw is a viable treatment modality with satisfactory outcomes.

Serratus Anterior-rib Composite Flap Partial Thumb Reconstruction.

The serratus anterior-rib composite flap is a well described and versatile flap used for reconstruction in a variety of anatomical regions. However, reconstruction of a thumb defect using this flap has not been well described since first mentioned in the literature by the Buncke et al group 20 years ago. The authors describe the use of this technique for thumb reconstruction in a complex defect from a gunshot wound.

Management of Asymptomatic Patients With Textured Breast Implants: A Survey Analysis of Members of The Aesthetic Society.

BACKGROUND: The management of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has been well established. However, there is minimal data and significant variability in the management of asymptomatic textured implant (ATI) patients. OBJECTIVES: The purpose of this study was to survey members of The Aesthetic Society on management of ATI patients in order to understand trends in practice patterns. METHODS: Members of The Aesthetic Society were queried via an electronic survey regarding management of ATI patients. Anonymous responses were collected by QualtricsXM (SAP, Walldorf, Germany) survey software. Descriptive statistics were used to examine the data, reported as frequencies. All analyses were performed with IBM SPSS Statistics 26. RESULTS: The survey was sent to 2149 active and candidate members of The Aesthetic Society with a total of 470 responses (21.87% response rate). For ATI patients presenting with concerns regarding BIA-ALCL risk, 88.8% of respondents educate the patient with clinical follow-up and/or imaging. The other 11.2% of surgeons recommend implant removal with variability in capsulectomy technique. For ATI patients requesting surgery, 42.5% of respondents educate the patient with clinical follow-up and/or imaging. The majority of surgeons (57.6%) recommend removal of the implant, with 30% recommending total capsulectomies. CONCLUSIONS: There is considerable variability in how members of The Aesthetic Society manage ATI patients who request surgery. Future regulatory agency and professional society collaborative efforts should continue to aim for generation of high-level scientific data to aid in the counseling and management of ATI patients.

Defining Ideal External Female Genital Anatomy via Crowdsourcing Analysis.

BACKGROUND: Despite existing anthropometric data in the literature regarding the variation of female external genital anatomy, the ideal aesthetic characteristics have yet to be defined. OBJECTIVES: The authors utilized crowdsourcing to better evaluate preferred anatomic characteristics of external female genitalia. METHODS: Fifty-six total images were digitally created by altering the proportions of the labia minora, labia majora, and clitoral hood. Images with differing ratios were presented in pairs to Amazon Mechanical Turk (Seattle, WA, USA) raters. Three different experiments were performed with each varying 2 of the 3 image characteristics to permit 2-factor modeling. The Bradley-Terry-Luce model was applied to the pairwise comparisons ratings to create a rank order for each image. Preferences for each anatomic variable were compared with chi-squared tests. RESULTS: A total of 5000 raters participated. Experiment 1 compared differing widths of the labia majora and labia minora and determined a significant preference for larger labia majora width and mid-range labia minora width (P = 0.007). Experiment 2 compared labia minora width vs clitoral hood length and showed a statistically significant preference for wider majoras (P < 0.001) but no significant preference in clitoral hood length (P = 0.54). Experiment 3 compared clitoral hood length vs labia minora width and showed a statistically significant preference for mid-range labia minora widths (P < 0.001) but no significant preference in clitoral hood length (P = 0.78). CONCLUSIONS: Raters preferred a labia majora to labia minora width ratio of 3:1 with minimal preference in clitoral hood length.

Pediatric Trigger Digit Presenting in the Setting of Trauma.

BACKGROUND: Pediatric trigger digit is a relatively rare condition with incompletely understood etiology. In our practice, we noted a series of children presenting with pediatric trigger digit after an associated local trauma to the hand, which has not been previously described. The aim of this study was to analyze the nature of presentation of trigger digits, the accuracy of initial diagnosis, and the impact on treatment strategies used. METHODS: An institutional review board-approved retrospective review of our institution's experience with pediatric trigger finger from 2001 to 2015 was performed. RESULTS: Twenty-two patients with 26 affected digits were identified. Eighty-eight percent of patients were diagnosed with trigger thumb, whereas 3 patients (12%) had small finger triggering. Thirteen patients (59%) presented as outpatients, whereas 9 (41%) presented through the emergency department. All patients presenting to the emergency department were in the setting of recent minor trauma. Of this subset of patients, 67% had an incorrect initial diagnosis, leading to an average delay in treatment of 60 days. Ten patients (45% of total) were initially treated with immobilization versus surgical release of the A1 pulley. However, all but 2 of these patients required eventual A1 pulley release for persistent or recurrent triggering (88%). CONCLUSIONS: The cause of trigger digit in children remains incompletely understood and may be multifactorial. In this series, a traumatic component to presentation was found in a significant number of patients. This association with minor trauma may contribute to misdiagnosis and delay in definitive treatment. Although initial treatment with immobilization does not seem to impact surgical outcome, we found a high rate of failure with initial immobilization. Most patients required eventual surgical management, regardless of whether or not the initial presentation was associated with trauma. When performed, we found that A1 pulley release alone has safe, reliable results.

Lymphovenous Bypass Using Indocyanine Green Mapping for Successful Treatment of Penile and Scrotal Lymphedema.

Male genital lymphedema is a debilitating condition with significant physiologic and psychologic ramifications. Classical surgical treatments for male genital lymphedema include primarily ablative procedures through removal of excess soft tissue, which often have poor aesthetic and functional outcomes. Super microsurgical techniques (including lymphovenous bypass and lymph node transfers) are promising contemporary interventions. In this case report, we aim to share our experience of lymphovenous bypass with indocyanine green (ICG) lymphangiography in the management of penile and scrotal lymphedema. We performed ICG lymphography of the male genitalia and right thigh by injecting ICG at multiple sites followed by concomitant evaluation with a handheld fluorescent portable imager. Skin incisions were designed over the linear lymphatics upstream from the site of obstruction and dermal backflow. Four end-to-end and one end-to-side lymphovenous bypasses were performed. After completion, lymphovenous bypasses patency was confirmed by injecting ICG proximal to the incision and observing flow. At 10-month clinic follow-up, the patient showed marked improvement with improved skin tenting, softer tissues, improved sensation, visible dorsal penile vein, ability to retract foreskin for cleaning, and confidence to engage in sexual activities. This case report describes successful use of lymphovenous bypass in the treatment of penile and scrotal lymphedema using ICG lymphography intraoperatively to map functioning of superficial lymphatics. The full potential of this microsurgical approach is yet to be discovered, and future studies are needed to enhance the long-term outcomes for the treatment of penoscrotal lymphedema.

Facelift Performed Safely With Local Anesthesia and Oral Sedation: Analysis of 174 Patients.

BACKGROUND: Anesthesia for elective ambulatory procedures must provide appropriate pain control while minimizing perioperative risk. Local anesthesia in combination with oral sedation provides a safe office-based method of anesthesia for rhytidectomy. OBJECTIVES: The purpose of this analysis was to identify the incidence of traditional outcome parameters in ambulatory rhytidectomy performed with local anesthesia and oral sedation. METHODS: A retrospective chart review was performed on all patients who underwent office-based rhytidectomy under local anesthesia with oral sedation from February 2011 to May 2017. A total of 174 patients were included. The data collected included patient medical and surgical history, medications, body mass index, tobacco use history, operative time, technique, and concurrent procedures. All intraoperative and postoperative complications were recorded. RESULTS: One hundred and sixty-five patients were female (94.8%) and 9 were male (5.2%) a mean age of 57.6 years (SD ± 7.90). There were 46 complications, including 23 hematomas (13.2%), 6 seromas, 6 episodes of emesis, 5 infections, 4 scar deformities, and 2 ear deformities. Of the 23 hematomas, only 2 required operative evacuation with local anesthesia in the office procedure room. Twenty-one hematomas were small and managed with percutaneous needle aspiration, followed by surveillance. The 5 infections resolved after oral antibiotics only. There were no thromboembolic events or hospitalizations. CONCLUSIONS: The use of only local anesthesia in combination with oral sedation safely permits the performance of rhytidectomy with similar incidence of rhytidectomy-related complications without the risk related to general anesthesia.

Temporomandibular Joint Septic Arthritis.

Infection of the temporomandibular joint (TMJ) is a rare pediatric condition resulting from the introduction of pathogens into the joint by hematogenous seeding, local extension, or trauma. Early recognition of the typical signs and symptoms including fever, trismus, preauricular swelling, and TMJ region tenderness are critical in order to initiate further evaluation and prevent feared complications of fibrosis, ankylosis, abnormal facial structure, or persistence of symptoms. Contrast-enhanced computed tomography with ancillary laboratory analysis including erythrocyte sedimentation rate, C-reactive protein, and white blood cell count are beneficial in confirming the suspected diagnosis and monitoring response to therapy. Initial intervention should include empiric parenteral antibiotics, early mandibular mobilization, and joint decompression to provide synovial fluid for analysis including cultures. This report describes a case of TMJ bacterial arthritis in a healthy 6-year-old male who was promptly treated nonsurgically with intravenous antibiotics and localized needle joint decompression with return to normal function after completion of oral antibiotics and physical therapy.

The Plastic Surgery Match: A Quantitative Analysis of Applicant Impressions From the Interview Visit.

BACKGROUND: The integrated plastic surgery match is a competitive process not only for applicants but also for programs vying for highly qualified candidates. Interactions between applicants and program constituents are limited to a single interview visit. The authors aimed to identify components of the interview visit that influence applicant decision making when determining a final program rank list. METHODS: Thirty-six applicants who were interviewed (100% response) completed the survey. Applicants rated the importance of 20 elements of the interview visit regarding future ranking of the program on a 1 to 5 Likert scale. Data were analyzed using descriptive statistics, hierarchical cluster analysis, analysis of variance, and Pearson correlations. A literature review was performed regarding the plastic surgery integrated residency interview process. RESULTS: Survey questions were categorized into four groups based on mean survey responses:1. Interactions with faculty and residents (mean response > 4),2. Information about the program (3.5-4),3. Ancillaries (food, amenities, stipends) (3-3.5),4. Hospital tour, hotel (<3).Hierarchical item cluster analysis and analysis of variance testing validated these groupings. Average summary scores were calculated for the items representing Interactions, Information, and Ancillaries. Correlation analysis between clusters yielded no significant correlations. A review of the literature yielded a paucity of data on analysis of the interview visit. CONCLUSIONS: The interview visit consists of a discrete hierarchy of perceived importance by applicants. The strongest independent factor in determining future program ranking is the quality of interactions between applicants and program constituents on the interview visit. This calls for further investigation and optimization of the interview visit experience.

Relationship between the nutritional status of breastfeeding Mayan mothers and their infants in Guatemala.

A case-control study was conducted to determine the association between maternal height and infant length-for-age, and to evaluate how this association is modified by either maternal or infant nutritional status. We hypothesised that maternal excess caloric intake [measured as body mass index (BMI)] would increase the association, while infant nutrition (measured in main meals consumed in addition to breastfeeding) will diminish the effect. Mother and infant pairs in Chimaltenango, Guatemala, were measured for anthropometric values and nutritional status, and mothers were interviewed to elicit nutritional and socio-economic information. Infant length was converted into z-scores based on the World Health Organization's (WHO) standards. Odds ratios (ORs), associated 95% confidence intervals (CIs) and the relative excess risk due to interaction (RERI) were calculated. Cases were infants below 2 z-scores of the WHO's length-for-age, while controls were infants within the -2 to 2 z-score range. Cases (n = 84) had an increased odds (OR: 3.00, 95% CI: 1.57-5.74) of being born to a stunted mother (below 145 cm) when compared with controls (n = 85). When adjusted for potential confounders, the OR decreased to 2.55 (95% CI: 1.30-5.02). Negative RERI values were produced for the joint exposure of maternal BMI ≥ 25 and maternal stuntedness (RERI: -0.96), as well as for the joint exposure of maternal stuntedness and infant nutrition (RERI: -2.27). Our results confirm that maternal stuntedness is a significant contributor to infant stuntedness; however, this association is modified negligibly by maternal nutritional status and significantly by infant nutritional status, each in a protective manner.
