RESUMEN

INTRODUCTION: Perioperative counseling regarding activity limitations is critical for patients undergoing dermatologic surgery. Current postoperative instructions regarding activity limitations may be inadequate, but this cannot be determined without knowing patient expectations. The study objective was to elucidate patient expectations for counseling on postoperative activity limitations and to determine if increased counseling would impact patient planning pre or postoperatively. MATERIALS AND METHODS: Patients who had excisions on the neck, torso, or extremities at one institution in one calendar year by the same surgeon participated in a phone survey. Questions addressed preexisting activity level, activity changes after surgery, amount of counseling received, and perioperative counseling expectations. Multivariable logistic regression was used to determine factors associated with patient perceptions about counseling, activity limitations, and surgical outcomes. RESULTS: Patients counseled on postoperative activity limitations reported they were unlikely to have made further arrangements to their surgical/personavl schedule had they been given additional counseling. The inverse was also true. When patients received the amount of counseling they expected, they were less likely to want to reschedule surgery or adjust personal plans. Younger patients and those with surgery on the lower extremities were more likely to limit their activity for longer periods of time. CONCLUSIONS: As instructions on activity limitations become more transparent, patients can make informed decisions regarding their surgical and personal schedules. This study can guide dermatologic surgeons in adjusting postoperative instructions to improve patient understanding of activity limitations, compliance, and the overall quality of their surgical experience.

RESUMEN

BACKGROUND: Although current guidelines recommend a 5 mm surgical margin for the excision of melanoma in situ (MIS), increasing evidence has shown this may be suboptimal to achieve tumor clearance. OBJECTIVE: To evaluate margins required for optimal cure rates with excision of MIS on the head and neck and investigate tumor and/or patient factors in those requiring >5 mm margins to achieve tumor clearance. METHODS: A retrospective chart review was performed on 846 (807 primary and 39 recurrent) MIS cases on the head and neck treated in the authors' dermatologic surgery department over a 126-month (10.5 year) period. RESULTS: Sixty-two percent were cleared with 5 mm margins. A total of 15 mm margins were required to achieve a 97% clearance rate. Difference in clearance rate between margin thresholds was significant (P < .001). Tumor location on the cheek and larger preoperative size correlated with requiring >5 mm margins to achieve tumor clearance (P = .006 and P = .001, respectively). LIMITATIONS: This is a single-center retrospective study which relies on accurate documentation of clinical data. CONCLUSION: This study demonstrates that MIS on the head and neck often requires margins >5 mm margins to achieve tumor clearance. When Mohs micrographic surgery is not possible, excision margins of ≥10 mm are likely necessary for head and neck tumors.

RESUMEN

BACKGROUND: Patients are often advised to keep the initial post-operative dressings dry and undisturbed for 24 to 72-hours. However, these requirements may result in significant disruption of patients' activities of daily living, such as bathing, leisure, and exercise. OBJECTIVE: Compare standard management of keeping wounds dry and covered (48-hours) with early (6-hours) post-operative water exposure METHODS: Investigator-blinded, randomized (1:1), controlled trial evaluating rate of infection and additional outcomes of interest. RESULTS: Overall, 437 patients randomized to either the early (6-hour) water exposure (n = 218) intervention group or the standard cohort (n = 219). The incidence of culture-proven infection in the intervention group (1.8%) was similar to the standard group (1.4%) (p>0.99). There was also no difference in rates of bleeding or bruising. Scar assessment using the Patient and Observer Scar Assessment Scale (POSAS) revealed similar scar outcomes. LIMITATIONS: Single site, academic center. CONCLUSION: Surgical wounds can be allowed to get wet in the immediate post-operative period with no increased incidence of infection or other complications and with similar cosmesis.

RESUMEN

Atypical fibroxanthoma (AFX) and pleomorphic dermal sarcoma (PDS) are rare histomorphological variants of a disease spectrum. After ruling out other tumor entities by immunohistochemistry, PDS can be differentiated from AFX by infiltration into the subcutis, while AFX remains confined to the dermis. The therapeutic approach is more aggressive in PDS as it can potentially metastasize. We assessed the usefulness of preoperative sonography in differentiating between the two tumor entities by identifying a potential subcutaneous infiltration. In our patients (n = 13), preoperative sonography identified and differentiated AFX and PDS with 100% accuracy and even changed the initial histological suspicion of AFX to PDS in 3 cases (23%), which was confirmed after tumor resection. Preoperative sonography of these tumors could strengthen the clinical diagnosis, avoid a delay in therapy initiation and improve patient counseling. While for AFX, micrographic-controlled surgery suffices, for PDS, resection with 2 cm safety margins and lymph node sonography to rule out lymphonodal involvement is necessary. Hence, ultrasonography can improve clinical practice by providing helpful information for dermatosurgeons, which cannot be obtained during clinical examination.

RESUMEN

BACKGROUND: Dermatosurgical procedures are predominantly performed under local anesthesia, yet there are few studies on perioperative pain management for extensive or staged procedures under local anesthesia. The purpose of this study was to assess pain during dermatologic surgery, describe perioperative pain management, and identify factors that influence pain perception. PATIENTS AND METHODS: This prospective, monocentric study included inpatients undergoing dermatologic surgery under local anesthesia from April to December 2021. Preoperative demographic data, a pain questionnaire, and four psychometric questionnaires (PCS, LOT-R, SFQ, PHQ-9) were collected. Postoperative pain and analgesic use during the first 24 hours were recorded. RESULTS: A total of 120 patients (with a total of 191 interventions) were included in the study. Mean postoperative pain was reported to be very low (NRS < 2). Preoperative pain and expected postoperative pain were found to be predictive of postoperative pain. There was a strong correlation between catastrophizing and preoperative anxiety (r = 0.65) and a moderate correlation between depression and preoperative anxiety (r = 0.46). CONCLUSIONS: Dermatologic surgery under local anesthesia is generally considered painless. During preoperative counseling and assessment, attention should be paid to patients who fear surgery, report pain, or anticipate postoperative pain, as they have an increased risk of experiencing postoperative pain.

RESUMEN

BACKGROUND: Reconstruction of nasal defects is a challenging task due to the complex nasal geometry and the need for aesthetic considerations. The bilobe flap has emerged as a reliable technique for nasal reconstruction, particularly for defects involving the nasal tip, alae, and inferior dorsum. OBJECTIVE: This study presents a review of 31 patients who underwent bilobe flap reconstruction for nasal defects after tumor resection. MATERIALS AND METHODS: The surgical technique, short- and long-term aesthetic outcomes, patient satisfaction, and complications were evaluated. Aesthetic outcomes were assessed using a qualitative ordinal scale, and long-term patient satisfaction was obtained through follow-up notes and phone interviews. RESULTS: Bilobe flap reconstruction yielded good aesthetic outcomes in the majority of cases, with high patient satisfaction. Complications were minimal, and revision surgeries were performed in a small number of cases to address aesthetic concerns. CONCLUSION: Overall, the bilobe flap technique proved to be an effective and reliable option for nasal reconstruction, providing stable and long-lasting results.

RESUMEN

BACKGROUND: Paronychia is a prevalent clinical disease affecting the soft tissue surrounding the nails. Most cases of toenail paronychia are commonly associated with ingrown toenails. While conservative treatment is effective for mild cases of ingrown toenails, surgical intervention becomes necessary for moderate to severe cases, particularly when granulomas form. OBJECTIVE: To provide a systematic understanding of these classic and modified procedures for surgeons to select the appropriate surgical interventions for patients suffering from moderate to severe ingrown toenails and discuss this technology's advantages and limitations for dermatologic surgery. METHODS: A literature search was performed using PubMed/MEDLINE and Google Scholar databases. Studies discussing surgical intervention for ingrown toenails were included. Moreover, the surgical steps were meticulously depicted by detailed schematic diagrams. RESULTS: These surgical techniques can be divided into three categories: matrix resection, debulking of periungual soft tissues, and the rotational flap technique. Each approach possesses distinct advantages and limitations. CONCLUSION: For moderate to severe cases, surgical interventions may exhibit superior outcomes, faster recovery times, and lower recurrence rates. The surgeon must possess a comprehensive understanding and proficient skillset in various surgical techniques for ingrown toenails.

RESUMEN

Dermatologic surgery is associated with a very low risk of complications. There is no widely accepted, evidence-based protocol with recommendations for postoperative wound care after dermatologic surgery. In this narrative review, we will be discussing the evidence on surgical wound care products and procedures. Overall, we found relatively few studies and, in many cases, a lack of statistically significant differences, possibly because of the low rate of complications. We'll be discussing the evidence on when we should initiate wound care procedures and their frequency, the type of ointment and antiseptics that should be applied, and the type of dressings that should be used. Despite the very few studies available on postoperative wound care following dermatologic surgery, there is sufficient evidence as to not recommend the use of prophylactic topical antibiotics. We also analyze the currently available evidence on surgical wound care in special situations, such as management of skin grafts, partial skin graft donor sites, xenografts/biomembranes, and surgical wounds to the legs.

RESUMEN

BACKGROUND: The reconstruction of surgical defects in high-tension anatomical regions is challenging due to the ischemia and subsequent necrosis associated with tension closure. Research on new flaps capable of closing these defects exerting less tension would be a tremendous advancement in dermatological surgery. PATIENTS AND METHODS: We conducted a multicenter, retrospective study that used 2 new flaps-the bishop and the sigma ones-to repair surgical defects in high-tension regions such as the scalp, lower extremities, and the nasal pyramid. The bishop flap was used in 9 patients, 5 of whom exhibited their lesion in the nasal pyramid, 2 in the legs and another 2 in the scalp. The sigma flap was used in 6 patients, 5 of whom exhibited scalp lesions and 1 leg lesion. RESULTS: Uneventful and excellent results were obtained in all 15 patients due to infection, dehiscence, or necrosis. CONCLUSIONS: Both the bishop and the sigma flaps are a good alternative to repair surgical defects in high-tension regions such as the scalp, lower extremities, or the nasal pyramid.

RESUMEN

BACKGROUND: Despite the importance of patient satisfaction in ensuring high-quality care, studies investigating patient satisfaction in Mohs micrographic surgery (MMS) are limited. OBJECTIVE: We investigated the factors associated with patient satisfaction in MMS for nonmelanoma skin cancer and how patient satisfaction changes in the postoperative period. METHODS: In this prospective cohort study including 100 patients, patient satisfaction surveys were administered at the time of surgery and at 3 months postsurgery. Sociodemographic characteristics, medical history, and surgical parameters were collected by chart review. Univariate linear and logistic regression models were created to examine these relationships. RESULTS: Decreased satisfaction was observed in patients requiring 3 or more MMS stages both at the time of surgery (P = .047) and at 3 months post-surgery (P = .0244). Patients with morning procedures ending after 1:00 pm had decreased satisfaction at the time of surgery (P = .019). A decrease in patient satisfaction between the time of surgery and 3 months postsurgery was observed in patients with surgical sites on the extremities (P = .036), larger preoperative lesion sizes (P = .012), and larger defect sizes (P = .033). LIMITATIONS: Single-institution data, self-selection bias, and recall bias. CONCLUSION: Patient satisfaction with MMS is impacted by numerous factors and remains dynamic over time.

RESUMEN

BACKGROUND: After excision surgery in patients with hidradenitis suppurativa (HS), wounds are usually left open for secondary intention healing. To evaluate wound healing, reliable wound measurement is important. However, digital wound measurement tools for measuring the surface area are validated for small wounds located on flat or mildly convex body surfaces in studies, often powered inadequately. Up until now, a validated digital measurement tool to accurately measure wounds on all body surfaces, including the intertriginous areas, was not available. OBJECTIVES: The aim of this study was to validate two digital wound measurement tools for the measurement of the surface area of larger and concave wounds, using surgical wounds in patients with HS. METHODS: This prospective observational validation study included consecutive patients with HS undergoing excision surgery in the Department of Dermatology of the Erasmus University Medical Center, Rotterdam. Wound measurements using a ruler, the tracing method, the inSight® 3-dimensional (3D) device, and the ImitoWound app were performed by three investigators. The intraclass correlation coefficients (ICCs) for concurrent validity and the intra- and inter-rater reliability were analyzed. The standard error of measurement (SEm) and minimal detectable change were calculated, and Bland-Altman plots were constructed to determine the limits of agreement. RESULTS: Twenty patients with a total of 52 wounds were included. The wounds had a mean surface of 18.7 cm2. The inSight® 3D device showed an ICC of 0.987 for concurrent validity, 0.998 for intra-rater reliability, and 0.997 for inter-rater reliability. The ICCs from the ImitoWound application were 0.974, 0.978, and 0.964 for concurrent validity, intra-rater reliability, and inter-rater reliability, respectively. The SEms for intra- and inter-rater reliability were 0.95 cm2 and 1.11 cm2 for the inSight® 3D device and 3.33 cm2 and 3.51 cm2 for the ImitoWound app, respectively. CONCLUSION: Both the inSight® 3D device and the ImitoWound app demonstrated excellent concurrent validity and reliability for the surface measurements of concave wound, enabling these tools to be used reliably in clinical research and daily practice. Furthermore, it paves the way for broader application, such as telemonitoring of wound care at home.

RESUMEN

BACKGROUND: In November 2018, Mohs micrographic surgery (MMS) was restricted to fellows registered with the Australasian College of Dermatologists. Three new item numbers for the provision of MMS were also introduced. We examine the national and state usage of MMS item numbers based on Medicare claim statistics and Mohs surgeons' self-reported data, noting the impact of the pandemic and the usage of individual item numbers. METHODS: Medicare item number data were obtained from the Medicare Benefits Schedule website for January 2017-December 2021. Self-reported data were collected on an annual basis by the Royal College of Pathologists of Australasia (RCPA) as part of the Quality Assurance Program (QAP) from 2019 onwards. Data were analysed with the Holt-Winters smoothing method for forecasting. RESULTS: An increasing number of MMS claims were processed each year, with a total of 89,183 for the study period. Since November 2018, 97.7% of procedures have been conducted on the head, neck, genitalia, hand, digits, leg (below the knee) or foot. The provision of services across the country was maintained during the pandemic years of 2020-2021, with an increase in services in Queensland. There were discrepancies between the states for procedures performed in greater than six sections; these constituted more than 35% of claims in Queensland and Western Australia compared to less than 15% in other states. The pandemic impacted certain states more than others, with Victoria and the Northern Territory having significantly fewer presentations than predicted (p < 0.05). CONCLUSIONS: Overall, the use of MMS in Australia is in keeping with peer-developed guidelines, despite discrepancies between states. Although certain states were more severely affected by the pandemic, MMS is increasingly used in Australia.

RESUMEN

The aim of perioperative antibiotic prophylaxis (PAP) is to prevent the occurrence of surgical site infections (SSIs) or other infectious complications (especially bacterial endocarditis or septic arthritis). PAP is effective in surgeries where overall infection rates are high even without considering patient-related risk factors (such as orthopedic surgery or fracture repair). Surgery on airways, gastrointestinal, genital, or urinary tract is also considered to be associated with a risk of infection and may require PAP. Overall, SSIs in skin surgery are relatively rare and vary between 1% and 11% depending on the localization, complexity of the wound closure and patient cohort. Therefore, the general surgical recommendations regarding PAP only partially reflect the needs of dermatologic surgery. In contrast to the USA, where recommendations on the use of PAP in skin surgery already exist, there are currently no guidelines for the use of PAP specifically designed for dermatologic surgery in Germany. In the absence of an evidence-based recommendation, the use of PAP is guided by the experience of the surgeons and leads to a heterogeneous use of antimicrobial substances. In this work, we summarize the current scientific literature on the use of PAP and make a recommendation depending on procedure- and patient-related risk factors.

RESUMEN

In addition to prevention of surgical site infections after skin surgery, perioperative antibiotic prophylaxis (PAP) aims to prevent the occurrence of other postoperative infectious complications, especially bacterial endocarditis and hematogenous joint prosthesis infections. This article discusses specific indications for the use of PAP. For example, patients who have undergone any type of heart valve replacement, including transcatheter valve replacement or use of prosthetic material to correct the heart valve, or patients who have experienced bacterial endocarditis, require PAP during skin surgery on mucosal membranes or ulcerated tumors. The use of PAP in special situations such as secondary wound healing, septic dermatosurgery or ulcer surgery is also presented and discussed in detail in this paper based on the current scientific literature. This paper represents the second part of the position paper of the Antibiotic Stewardship Working Group of the German Society for Dermatologic Surgery (DGDC) and summarizes evidence-based recommendations for the administration of PAP during skin surgery for special indications and situations. This is particularly important because, as detailed in Part 1 of this position paper, PAP can and usually should be avoided in skin surgery.

RESUMEN

BACKGROUND: The efficacy of Mohs micrographic surgery (MMS) in treating cutaneous squamous cell carcinoma has been demonstrated. The cost effectiveness of MMS has rarely been studied to support the perceived higher cost. OBJECTIVE: Perform a cost-effectiveness analysis to determine whether MMS is cost effective over wide local excision (WLE) for Brigham and Women's Hospital tumor stage T2a cutaneous squamous cell carcinoma over a 5-year period. METHODS: A Markov model with a 5-year time horizon was created using variables from published data. Costs in United States dollars and quality-adjusted life-years (QALY) were calculated. RESULTS: MMS was $333.83 less expensive ($4365.57 [95% CI, $3664.68-$6901.66] vs $4699.41 [95% CI, $3782.94-$10,019.31]) than WLE. MMS gained 2.22 weeks of perfect health (3.776 QALY [95% CI, 3.774-3.777] for MMS and 3.733 QALY [95% CI, 3.728-3.777]) over 5 years. The incremental cost-effectiveness ratio was -$7,822.19. MMS had a 99.9% probability of being more cost effective than WLE. Annualized savings of choosing MMS over WLE would be $200 million and over 25,000 QALY. MMS could cost 3.1 times its current rate and remain cost effective. LIMITATIONS: Relied on data from external retrospective sources. CONCLUSION: MMS is less costly and more effective than WLE and should be strongly considered for stage T2a cSCC, given improvements in costs and QALY.

RESUMEN

Congenital melanocytic nevi (CMN) are quite common benign proliferations of cutaneous melanocytes. They are present at birth or arise during the first few weeks of life being upper and lower extremities one of the most common locations. To date, consistent guidelines for clinical management of CMN do not yet exist and the main reasons for removing them are medical and cosmetic. Regardless of the cause of having a CMN removed, when it comes to surgical excision of the lesion in daily practice, the single most important decision to make is how to properly close the post-excisional defect. The local Dufourmentel skin flap seems to be a reliable solution for surgical treatment of medium-sized CMN on the limbs. It takes advantage of skin laxity adjаcent to thе defect to allоw the transpositiоn of tissuе with similаr charactеristics tо the tissuе еxcisеd, which is the key for achieving good aesthetic and functional outcomes. In this brief clinical study, the author identified a group of adult patients, who had medium-sized CMN located on their extremities. The surgical technique is explained and useful tips are given. No complications and high patient satisfaction rate were registered in the series. Dufourmentel flap is a useful tool in the armamentarium of dermatologic surgery when dealing with medium-sized CMN on the extremities. Furthermore, due to its versatility this flap could also be applied for other clinical indications both benign and malignant.

RESUMEN

Antibiotics have been used as a prophylaxis for dermatologic procedures. We will review the various procedures that specific antibiotics with dosages are used for, depending on the procedure, diagnosis, and circumstance of the patient. We will examine the current and updated guidelines used in dermatologic surgery and the overlapping guidelines across other fields. Physicians must consider the side effects of antibiotics and the resistance that may occur as a result before using the class or level of prophylaxis. Initial evaluation for alcohol, chlorhexidine, or iodine should be measured as well. Updated guidelines aim to address the contraindications of antibiotics, yet further research is needed to avoid antibiotic resistance and to explore alternative methods of antibiotic application, such as intranasal and intravenous.

RESUMEN

Autologous non-cultured epidermal cellular grafting is the treatment of choice for patients with stable refractory vitiligo. Recently, studies have shown cost-effective alternatives for this procedure, superseding previous techniques that required large research facilities or expensive pre-packaged kits. We provide modifications to current techniques, including the use of individual Petri dishes to allow for processing larger skin grafts, hyfrecation instead of conventional manual dermabrasion of the recipient site to reduce scar formation as well as better margin delineation, and an intravenous giving set with a filter for improved filtration of the mixed cell population. These modifications facilitated sufficient skin repigmentation in a cost-effective outpatient setting.

RESUMEN

BACKGROUND AND OBJECTIVES: After local flaps, it may be necessary to reconstruct the contour of the nasal ala. This is possible with a single-stage all-layer shaping suture. In the present study, the functional and aesthetic results after single-stage reconstruction of the nasal ala were prospectively evaluated. PATIENTS AND METHODS: Patients who underwent surgery for skin tumors of the nose between 06/2019 and 06/2020 who required reconstruction of the nasal ala as part of the defect closure and had an all-layer suture used were prospectively included in the study. A standardized evaluation of aesthetic and functional outcome was conducted by the patient and a physician at discharge as well as 4 weeks later. Patients additionally underwent a follow-up survey 6 months later. RESULTS: Thirty-seven patients were included in the study. Four weeks postoperatively, all flaps were found to be fully healed and vital. Aesthetic outcome at 4 weeks was rated as very good or good by physicians in 73% and by patients in 78.4%. Persistent complications due to reduced blood flow were not observed. CONCLUSION: The reshaping of the nasal ala as part of the defect reconstruction with an all-layer suture demonstrates very good aesthetic as well as functional results and can be performed in a single-stage procedure. .

RESUMEN

Cryogen spray cooling (CSC) is widely applied in laser dermatologic surgery to minimize the risk of non-specific epidermal thermal damage caused by the competitive laser energy absorption of epidermal melanin. However, the light absorption and attenuation by cryogen film and subsequent frost formation on the skin surface during CSC are needed to be investigated by using R-134a, R-404A, and R-32. A spray system equipped with an integrating sphere-based light collection apparatus was constructed to evaluate the time-resolved laser transmittance and spectral absorption characteristics induced by R-134a, R-404A, and R-32 sprays, under the clinical-used 755-nm and 1064-nm laser irradiations. No obvious light absorption peaks exist in the wavelengths of 370-1400 nm. R-404A produces the largest average light absorbance (0.089), as compared to those of R-134a (0.066) and R-32 (0.068) in the near-infrared range (780-1400 nm). Given the lowest boiling point and highest latent heat of R-32, the evaporation of liquid film and melting of subsequent frost are promoted, leading to smallest light attenuation. R-32 spray shows great potential in clinics owing to its high light transmittance, small light absorption, and high cooling capability. For R-32 spray, the durations between spurt termination and laser irradiation are recommended to be 8-100 ms and 13-100 ms with average light transmittances of 86% and 95% under 755-nm and 1064-nm laser irradiations.
