ABSTRACT
SUMMARY: In the occipital trigger site for migraine, the greater occipital nerve (GON) is thought to be irritated by surrounding structures, including the semispinalis capitis muscle and occipital artery (OA), producing headaches in the back of the neck. Thus, standard decompression involves removal of surrounding tissue and dissection away from the vessel. The authors noticed a consistent pattern between the GON and OA more distally: the OA approaching laterally and diving under the GON, the OA looping back over the GON and intertwining with the medial branch of the GON, and lastly the OA traveling parallel to the GON. The technique described uses a modified endoscopic approach with a counter incision, endoscopic assistance, and radical artery lysis to address distal sites in addition to the standard release. At the counter incision, distal intertwining between vessel and nerve was released. A high-definition endoscope was used to address dynamic compression points more proximally, including hidden areas where the vessel dives under the GON, as well as to facilitate cautery and removal of the vessel. Without the use of an endoscope and counterincision, it is difficult to achieve complete decompression of the nerve distally without injury to the proximal body of the nerve.

BACKGROUND: The greater occipital nerve is a common compression site for migraine or chronic headache, and variable relationships with the occipital artery have been shown in anatomical studies. Despite surgical decompression, there are still a subset of patients who have an incomplete response. In this article, the authors describe an observed clear and very consistent pattern between the nerve and artery, including both dynamic and static compression points, that must be evaluated for adequate treatment. METHODS: Seventy-one patients underwent occipital nerve decompression with high-definition videos and photographs, and the dynamic relationship between the greater occipital nerve and the occipital artery was recorded in a retrospective review. RESULTS: A consistent pattern existed in 92 percent of patients, as follows: (1) hidden proximal dynamic compression of the bottom surface of the nerve as the occipital artery comes laterally to dive under the greater occipital nerve; (2) more apparent dynamic compression on the upper surface of the nerve as the occipital artery loops back on top of the greater occipital nerve; (3) intertwining compression after the bifurcation of the greater occipital nerve as the artery wraps around the medial branch; and (4) parallel travel of the terminal branch of the greater occipital nerve with the occipital artery in close proximity. CONCLUSIONS: There is a consistent pattern in the relationship between the greater occipital nerve and the occipital artery after its exit from the trapezius fascia. It is possible that this relationship creates dynamic compression points, including hidden areas, that can only be deactivated by radical excision of the vessel.

BACKGROUND: Noninvasive treatments for skin tightening are gaining popularity. However, no studies have assessed bipolar fractional radiofrequency treatment on suprapatellar skin. OBJECTIVES: The purpose of this study was to evaluate the efficacy of bipolar fractional radiofrequency treatment on suprapatellar skin. METHODS: Twenty patients received 1 bilateral suprapatellar bipolar fractional radiofrequency treatment. They returned 7 days, 3 weeks, 3 months, and 6 months posttreatment. Noninvasive measurements were obtained at each visit, including high-resolution ultrasonography, optical coherence tomography, transepidermal water loss and skin elasticity. Microbiopsies were collected in the treatment area for histologic and gene expression analyses. Three clinicians completed photographic evaluations comparing texture and laxity at baseline vs 6 months posttreatment. RESULTS: Fifteen subjects completed all 6 visits. Both transepidermal water loss and dermal-epidermal junction roughness were increased at 3 weeks and 3 months posttreatment. Both attenuation coefficient and stiffness were increased significantly at 3 and 6 months posttreatment. Blood flow 0.5 mm below the surface and expression of epidermal hyaluronic acid and inflammatory genes IL-1b and IL-6 were significantly higher at 7 days posttreatment compared with pretreatment and 3 months posttreatment. There were no statistically significant changes in collagen- or elastin-related genes and proteins at 7 days or 3 months posttreatment. An improvement in texture and laxity was observed at 6 months posttreatment in 17.7% and 24.4% of photographs, respectively. CONCLUSIONS: Radiofrequency treatment by microneedling of suprapatellar skin shows limited effects in decreasing skin laxity and improving skin appearance. At a molecular level, the treatment resulted in lower elastin and hyaluronic acid levels and increased dermal-epidermal junction roughness based on histology and optical coherence tomography imaging.

BACKGROUND: As the number of patients requiring bariatric surgery has increased, so has the demand for body contouring after massive weight loss. Surgery involving the abdomen in these patients is particularly challenging as both vertical and horizontal laxity if often present, making traditional abdominoplasty techniques less effective. OBJECTIVES: The aim of this study was to review the operative technique and evaluate the preoperative comorbidities and operative decisions that may impact patient outcomes in those undergoing vertical abdominoplasty. METHODS: A review of the authors' technique is described. A retrospective chart review of patients who underwent vertical abdominoplasty for significant vertical and horizontal laxity after massive weight loss by a single surgeon between June 2007 and July 2019 was performed. Preoperative parameters, operative factors, and minor and major complications were evaluated. RESULTS: Our complication rate was 81% (13/16), which were all minor. No major complications were encountered. Patients with a history of nicotine use had a 100% complication rate. There was a trend toward higher seroma formation in patients with coronary artery disease and those with a history of smoking. There was also a trend toward higher wound dehiscence in patients with renal disease. The authors found no statistically significant correlation between complications and older age, higher weight of tissue resected, higher body mass index, and medical comorbidities. CONCLUSIONS: This small series helps to elucidate the role of vertical abdominoplasty in the care of patients following massive weight loss and its associated morbidity. Proper patient selection, appropriate preoperative patient counseling, and sound surgical technique help to mitigate the negative outcomes.
ABSTRACT
BACKGROUND: Skin scarring can occur after punch biopsies, prohibiting their routine utilization, especially in the central face. OBJECTIVES: This paper describes a scarless, 0.33-mm-diameter skin microbiopsy for molecular analysis of skin. METHODS: This is was single-center, randomized, prospective study with 15 patients receiving no biopsy or biopsy on the left or right nasolabial fold. Six blinded raters assessed participant photos at baseline, 1 month, and 3 months post biopsy to evaluate for a visualized scar. Patient and Observer Scar Assessment Scale was completed. Additionally, biopsies from various skin regions of body along with arm skin after treatment with a single Erbium-YAG laser were processed for molecular analysis. RESULTS: No patients exhibited scar formation based on evaluation of photographs and patient feedback. There was no mark at the biopsy site 7 days post-procedure. Optical coherence tomography showed a complete closing of the biopsy-punch wound 48 hours post-biopsy. One month post-biopsy, photography reviewers were unable to identify a scar, on average, 90% of the time at 3-month follow-up. Microbiopsies from various anatomical regions were successfully extracted for histology, electron microscopy, and gene expression analysis. Selected skin rejuvenation markers in the biopsies from Erbium-YAG-treated forearm skin resulted in significant gene upregulation in extracellular matrix molecules at 1 month posttreatment compared with untreated skin. CONCLUSIONS: A core microbiopsy of 0.33 mm can be extracted reproducibly for histological, ultrastructural, and gene expression analysis without scarring. This allows repeated sampling for assessment of skin treatments and diseases, including aesthetics and wound-healing progress.

BACKGROUND: Migraine surgery is an increasingly popular treatment option for migraine patients. The lesser occipital nerve is a common trigger point for headache abnormalities, but there is a paucity of research regarding the lesser occipital nerve and its intimate association with the spinal accessory nerve. METHODS: Six cadaver necks were dissected. The lesser occipital, great auricular, and spinal accessory nerves were identified and systematically measured and recorded. These landmarks included the longitudinal axis (vertical line drawn in the posterior), the horizontal axis (defined as a line between the most anterosuperior points of the external auditory canals) and the earlobe. Mean distances and standard deviations were calculated to delineate the relationship between the spinal accessory, lesser occipital, and great auricular nerves. RESULTS: The point of emergence of the spinal accessory nerve was determined to be 7.17 ± 1.15 cm lateral to the y axis and 7.77 ± 1.10 caudal to the x axis. The lesser occipital nerve emerges 7.5 ± 1.31 cm lateral to the y axis and 8.47 ± 1.11 cm caudal to the x axis. The great auricular nerve emerges 8.33 ± 1.31 cm lateral to the y axis and 9.4 ±1.07 cm caudal to the x axis. The decussation of the spinal accessory and the lesser occipital nerves was found to be 7.70 ± 1.16 cm caudal to the x axis and 7.17 ± 1.15 lateral to the y axis. CONCLUSION: Understanding the close relationship between the lesser occipital nerve and spinal accessory nerve in the posterior, lateral neck area is crucial for a safer approach to occipital migraine headaches, occipital neuralgia, and new daily persistent headaches and other reconstructive or cosmetic operations.

BACKGROUND AND OBJECTIVE: Patient-reported outcomes and blinded observer rating scales are subjective and unreliable but are extensively utilized to evaluate cosmetic office-based treatments, including ablative lasers. This study aims to assess the practicality of using non-invasive and minimally invasive methods for objective skin assessment following a skin rejuvenation treatment. STUDY DESIGN/MATERIALS AND METHODS: Twelve patients received a single 1,470/2,940 nm laser treatment for facial rejuvenation. Assessments were performed before treatment, and 7 days, 3 weeks, and 3 months post-treatment. Images were taken with the VISIA Skin Analysis System to measure wrinkles, textures, pores, ultraviolet (UV) spots, brown spots, red areas, and porphyrins. Other non-invasive skin measurements-high-resolution ultrasonography, optical coherence tomography, transepidermal water loss and BTC 2000-were used to measure epidermal/dermal thickness, blood flow, surface roughness, wrinkle depth, attenuation coefficient, elasticity, laxity, and viscoelasticity. Microbiopsies (0.33 mm in diameter or the equivalent of a 23-gauge needle) were collected for histology and gene expression of tissue rejuvenation. RESULTS: Significant improvement in facial skin aesthetics after laser treatment was recorded in UV spots, brown spots and pores after 3 weeks and in UV spots and brown spots after 3 months. The dermal attenuation coefficient decreased significantly at 3 weeks, while blood flow 0.5 to 0.7 mm below the skin surface increased significantly between 5 days and 3 weeks following treatment. Epidermal hyaluronic acid expression assessed by immunostaining and expression of inflammatory genes were elevated at 7 days post-treatment compared with untreated or 3 months post-treatment. There were no statistically significant changes in collagen or elastin-related genes between groups at the studied parameters. CONCLUSION: Non-invasive devices can be effectively used to provide objective measurements of skin structure, pigmentation, blood flow, and elasticity to assess the efficacy of facial skin rejuvenation treatments. Furthermore, microbiopsies can objectively evaluate facial skin rejuvenation without scarring. Using non-invasive skin imaging, a single treatment with the 1,470/2,940 nm laser was observed to be effective in improving skin appearance after 3 months, namely in reducing UV spots and brown spots, without significant changes in the tissue at the molecular level, as assessed by microbiopsy.

ABSTRACT
Inadequate tissue perfusion is a serious complication following reconstructive surgeries. Skin flap necrosis, especially in the head and neck area, may have significant cosmetic consequences. Although clinical exam is the mainstay in evaluating perfusion, it may not always predict ischemic problems. The SPY Elite laser angiographic system, which has been widely used to analyze tissue perfusion in postmastectomy skin flaps, has been shown to be able to evaluate tissue perfusion objectively. We describe a revision rhinoplasty case where hypoperfusion of the nasal tip was seen following placement of structural grafts to the nasal tip, and before the grafts being removed SPY, angiography was used to evaluate if topical nitroglycerin alone could correct hypoperfusion of the nasal tip rather than removal of structural grafts. A SPY angiography was performed to evaluate the hypoperfusion to the nasal tip. Repeat imaging was then performed following treatment with topical nitroglycerin alone. Perfusion of the nasal tip was restored and confirmed by SPY angiography system. The objective findings from the SPY angiography allowed the grafts to remain in place and lead to optimal cosmetic result. Due to the critical information SPY angiography provided in this case, we recommend the use of technology when evaluating reconstructive cases in which the viability of the tissue may be difficult to deduce from clinical exam.
ABSTRACT
Femoral artery reconstructive operations pose the risk of damage to the lymphatic system and leakage of lymph fluid into the groin. This leakage establishes a stagnant reservoir of protein-rich fluid, further placing the patient at risk for complications, especially a higher infection rate. The use of SPY technology (Stryker Corp/Novadaq Technologies, Kalamazoo, Mich) for lymphatic leaks have been described in previous studies. However, the management of persistent high-output lymphatic leaks addressed secondarily with SPY lymphangiography have yet to be reported. This case report describes a young male who underwent thrombectomy in the left common femoral artery, who presented several days later with a high-output chylous leak. The lymphatic leak was initially managed and failed conventional muscle flaps, and SPY lymphangiography was performed to manage the lymphatic leak during the secondary surgery. The lymphatic vessels were ligated and confirmed with SPY lymphangiography. The management of lymphatic groin complications aided by the use of SPY lymphangiography provided valuable data and allowed for better intraoperative visualization. Utilization of SPY technology allowed the surgeons to properly address all sites of leakage in an otherwise persistent lymphatic leak. Resolution of lymphatic leak was further confirmed with SPY. Lymphatic complications, particularly those in the groin area, are of significant concern to physicians. Any suspected chylous leak should be followed with SPY lymphangiography to ensure proper treatment and resolution. Prophylactic use of SPY technology in high-risk patients during lymphatic surgery of the groin may also be considered.
ABSTRACT
Skin flap necrosis occurs in 1-3% of facelift procedures. The SPY Elite Fluorescence Imaging System has been widely used in evaluating mastectomy skin flaps for breast reconstruction but has not been described in assessing skin flaps during facelifts. This case report describes the intraoperative use of SPY to assess flap perfusion during a high-risk facelift and static sling for the correction of facial paralysis. The use of intraoperative SPY during this high-risk facelift allowed for the timely assessment of perfusion, successful intervention of nitroglycerin paste to improve blood flow, and prevention of any additional surgical interventions. SPY may have a more widespread role in facelift patients with a higher risk of skin flap necrosis.
ABSTRACT
The SPY angiography system has several surgical uses. Often, surgeons may experience difficult cases in which the viability and perfusion of tissue is questioned. By using the SPY angiography system intraoperatively, this system may provide additional information allowing the surgeon to make calculated real-time decisions which may lead to improved patient outcomes. This study describes a case of a chronic sternal wound treated with reconstruction using intraoperative SPY angiography. Adequate perfusion of the flap was determined via SPY angiography intraoperatively. The flap was thereafter successfully utilized to cover the chronic wound. The patient was followed postoperatively with progression of wound closure. Sternal wounds often pose a complex problem for patients and physicians. The use of intraoperative SPY angiography provided critical information to the operating team allowing for the successful identification of a viable flap. The use of SPY angiography provided the patient an opportunity to achieve a successful outcome and reduced the risk of skin necrosis or reoperation.
ABSTRACT
Objective: There are very few studies reporting the techniques utilized in penile replantation. Of those in literature, many agree that the use of microvascular technique results in better outcomes. The most common complications are skin necrosis and venous congestion, which are even higher in replants without arterial supply. Methods: This study describes a case of self-inflicted penile amputation treated with microsurgical replantation and managed postoperatively with hyperbaric oxygen therapy and Cialis (tadalafil), and SPY angiography. The penile replant had extensive skin necrosis, which prevented a sufficient clinical evaluation of the replanted penis. Serial SPY angiography was performed to assess tissue viability, following hyperbaric oxygen therapy and Cialis treatment. Results: SPY angiography was critical to the decision making of the operating team in the management of this case of penile replantation. Conclusions: The use of SPY angiography prevented the patient from undergoing revision amputation and allowed for a safe and successful penile replantation.

Many dermatologic conditions affect the axillae; however, identification is often difficult due to similar clinical presentations. The axillae are unique due to their increased humidity, as well as their high density of hair follicles and sweat glands. Furthermore, they are a site of increased friction due to the presence of closely opposing skin surfaces. In addition to the axillae being involved with common skin diseases affecting other body surface areas, these unique factors also predispose the axillae to less common skin manifestations. This review categorizes the various conditions based on their inflammatory or infectious etiology and describes each condition based on their predominant characteristics, such as lesion type and color, methods of diagnosis, and treatment. Overall, the goal of this review is to provide a broad differential of conditions affecting the axillae so that conditions can be differentiated from one another and treated effectively.

Most medical schools in the United States have an associated student-run free clinic (SRFC) providing medical care to the underserved population around the campus. SRFCs provide students with opportunities to practice history-taking and diagnosis skills. There have been a few studies that have evaluated patient satisfaction within SRFCs; however, these studies report limited aspects of care within these clinics. This study hopes to determine the levels of satisfaction with clinical staff and operations and to ensure that the medical needs of patients are being met. Results showed that 91% of the patients were satisfied or very satisfied with their overall clinic experience. The highest scoring parameters were "courtesy/respect of staff", "availability of free or affordable medications", and "doctor's knowledge". Overall, the patients are satisfied with the staff, care, and availability of medicine provided by the Keeping Neighbors in Good Health Through Service (KNIGHTS) clinic. Most patients enjoy participating in the training and education of future physicians and would recommend this clinic to a friend or family member. The lowest satisfaction rates were associated with length of visit and wait time. In the future, SRFCs should work together to assess patient satisfaction in the clinics, identify problem areas, and develop generalizable interventions for improvement.
