A Pearl for Pretibial and Forearm Repair Following Mohs Micrographic Surgery.

Wound repair of the pretibial and forearm regions presents a challenge during dermatologic surgery as these areas are under significant tension and exhibit increased skin fragility. Various methodologies have been proposed for the closure and repair of such wounds, however, the use of the bilayered suture technique may be simpler and more effective than other techniques such as the pinch stitch, pully stitch, slip-knot stitch, pulley set-back dermal suture, horizontal mattress suture, pully stitch, and tandem pulley stitch. Our objective was to describe a novel method for the repair of pretibial and forearm wounds following Mohs micrographic surgery utilizing bilayered closure followed by tissue adhesive application.  J Drugs Dermatol. 2024;23(5):380.     doi:10.36849/JDD.7139  .

Postinflammatory Hyperpigmentation Following Mohs Micrographic Surgery: An Observational Study.

IMPORTANCE: Functional and cosmetic outcomes following Mohs micrographic surgery (MMS) are poorly studied in individuals with skin of color (SOC). Postinflammatory hyperpigmentation (PIH) may be long-lasting and highly distressing. SOC individuals are particularly susceptible to PIH following procedures.  Objective: To characterize factors that contribute to the development of PIH following MMS in SOC. DESIGN: This retrospective study included 72 SOC individuals with 83 cases of keratinocyte carcinoma treated with MMS between August 2020 and August 2021 at a single medical center in the Bronx, New York. RESULTS: Postinflammatory hyperpigmentation following Mohs micrographic surgery was more common in Fitzpatrick skin types (FST) IV to V (48.0%) compared to FST I to III (18.2%; P=0.006). Grafts and granulation resulted in higher rates of PIH compared to linear repairs and flaps (87.5% vs 30.7%; P=0.003). Cases with postoperative complications resulted in higher rates of PIH compared to cases without (81.8% vs 29.2%; P=0.001). In a subset analysis of linear repairs, polyglactin 910 as a subcutaneous suture produced a higher rate of PIH compared to poliglecaprone 25 (46.2% vs 7.1%; P=0.015).  Conclusions and Relevance: Individuals with SOC (FST IV to V) are more likely to develop PIH following MMS. Grafts and granulation lead to PIH more often than linear repairs and flaps. Postoperative complications significantly increase the risk of PIH. Surgeons should consider these risk factors during surgical planning in an effort to mitigate PIH in SOC individuals. Studies with larger sample sizes are indicated.  J Drugs Dermatol. 2024;23(5):316-321. doi:10.36849/JDD.8146.

Results of Mohs' Micrographic Surgery of Periocular Basal Cell Carcinoma: The Swedish Experience.

The Department of Ophthalmology, Sahlgrenska University Hospital, has until recently been the only eye clinic in the Nordic countries to perform Mohs' micrographic surgery of basal cell carcinoma. This has led to the practice of only the most complicated basal cell carcinomas being operated on with this technique. The purpose of this study was to present the results of these surgeries in patients with at least 5 years of follow-up. A retrospective study of all patients operated upon in 2010-2015 was performed. Data were gathered from their medical charts. Primary outcome was recurrence of basal cell carcinoma. One-hundred and sixty-seven patients were operated on. Mohs' micrographic surgery was used for tumours that were judged as highly aggressive on preoperative biopsy, had ill-defined borders, had recurred after previous surgery, or a combination of these factors. Nine recurrences (5.4% of all radical Mohs' micrographic surgeries) were diagnosed after a mean postoperative time of 37 months (4-84 months). Interestingly, all of these 9 recurrences after Mohs' micrographic surgery were in patients who had such surgery because of a recurrent basal cell carcinoma to start with. Good results can be achieved when operating on the most complicated periocular basal cell carcinomas with Mohs' micrographic surgery but special care has to be taken to ensure radical borders when operating on recurring basal cell carcinomas.

Laser Applications in Wound and Scar Management Post-Mohs Micrographic Surgery: A Systematic Review.

Mohs micrographic surgery (MMS) can lead to complications such as scarring and delayed wound healing, particularly in sensitive areas such as the face, neck, and chest. This study aims to assess the evidence regarding the use of lasers post-MMS for wound healing and scar revision. A comprehensive systematic review of the literature was performed using databases including MEDLINE, PubMed, EMBASE, Web of Science, Cochrane Library, and CINAHL from inception until July 25, 2022. A total of 2147 unique studies were identified, from which 17 were included in the analysis. A total of 17 studies reported applications of lasers with favourable efficacy including wound healing (n = 1), resurfacing of full-thickness skin grafts and split-thickness skin grafts (n = 4), periscar telangiectasias (n = 1), functional scar contractures (n = 2), and scar texture (n = 9). Minimal adverse effects were reported with the use of lasers post-MMS. Overall, the use of lasers post-MMS is a safe and well-tolerated option for scar revision with high patient satisfaction and is less invasive than surgical interventions.

Nasal Lining Repair: A Comprehensive Literature Review.

BACKGROUND: Currently, there are limited reviews in the dermatology literature on how to approach reconstruction of nasal lining in full-thickness nasal defects resulting from Mohs micrographic surgery. Given variable training and experience, dermatologic surgeons may seek additional references to help reconstruct certain advanced defects. We sought to synthesize literature from dermatologic surgery, plastic surgery, and otolaryngology to review repair options and considerations for repair of nasal lining defects. OBJECTIVE: To present a comprehensive literature review of repair options for nasal lining reconstruction and discuss advantages, disadvantages, specific anatomic considerations, and techniques to execute such options. MATERIALS AND METHODS: Articles from several different reconstructive specialties including dermatologic/Mohs surgery, otolaryngology, and plastic and reconstructive surgery were reviewed. Instructive images were compiled to illustrate several techniques, with additional medical illustration recreations included to help showcase important reconstructive approaches. RESULTS: A comprehensive descriptive review of nasal lining repair options for the reconstructive surgeon. CONCLUSION: Advanced tumors can result in full-thickness nasal defects, and this review describes various reconstructive options for reconstruction based on the extent of the defect.

A Comparison of Preoperative Telephone Call Versus Mailed Educational Materials on Patient-Reported Outcomes in Mohs Micrographic Surgery.

BACKGROUND: Preoperative education has uncertain benefits on the preparedness and satisfaction of patients undergoing Mohs micrographic surgery (MMS). OBJECTIVE: We sought to determine the effect of a preoperative telephone call on preparedness and satisfaction in patients undergoing same-day office consultation and MMS. MATERIALS AND METHODS: All new patients ( N = 208) scheduled for same-day office consultation and MMS were mailed a standardized preoperative packet. Approximately half of those patients were randomly selected to also receive a preoperative phone call. On the day of the surgery, patients completed an anonymous preoperative and postoperative survey assessing their preparedness and satisfaction with the preoperative education received. RESULTS: There was no significant difference in patient preparedness between the letter only (LO) and phone call and letter study groups. There was a significant difference in preoperative satisfaction-a higher percentage of LO patients were "somewhat satisfied" or "not satisfied" with the preoperative education received ( p = .013). CONCLUSION: Preoperative phone consultation, in addition to mailed educational materials, did not have a statistically significant effect on patient preparedness in patients undergoing MMS; however, there was a trend toward increased satisfaction with the preoperative education provided in patients who received a preoperative phone call.

Risk factors for developing depressive symptoms in the immediate postoperative period after Mohs micrographic surgery.

PURPOSE: Mohs micrographic surgery (MMS) is a highly efficacious, tissue sparing method of skin cancer removal. Nevertheless, in the months to years after MMS, psychosocial distress has been described. The present study addressed the immediate period after MMS and assessed the frequency and risk factors for development of depressive symptoms. METHODS: Subjects undergoing MMS at two physician practices (JL, FS) were included in this prospective cohort study. Preoperatively, a standardized depression screening, the Patient Health Questionnaire-8 (PHQ-8), was administered. After MMS, the PHQ-8 was readministered at weeks 1, 2, 4, 6, and 12. Average PHQ-8 score by week and change from baseline PHQ-8 score were the primary outcomes. RESULTS: Sixty-three subjects were included of which 49 (78%) had a facial site. Twenty-two subjects (35%) had some increase in score during the 12-week follow-up period, of which 18 had a facial site. The oldest subjects (83-99 years, n = 14) had significantly higher PHQ-8 scores at week 4 (p < 0.01) and week 6 (p = 0.02) than all other age groups. There were no differences in scores between location groups. CONCLUSIONS: One-third of subjects had some increase in score during the follow-up period. Those in the oldest age cohort were at highest risk of increased score. In contrast to prior literature, those with facial sites were not at higher risk. This difference may be explained by increased masking during the ongoing COVID-19 pandemic. Ultimately, consideration of patients' psychologic status in the immediate postoperative period after MMS, particularly in the elderly population, may enhance perceived patient outcomes.

Liposomal and Nonliposomal Bupivacaine for Mohs Surgery: A Systematic Review.

BACKGROUND: Lidocaine is the most commonly used local anesthetic for Mohs micrographic surgery (MMS), but given its limited half-life, postoperative pain remains a significant concern for patients. Bupivacaine is used in various surgical subspecialty procedures and has demonstrated improved pain control compared with lidocaine. However, its role in MMS is insufficiently explored. OBJECTIVE: To systematically review the current literature for reports on use of bupivacaine, traditional nonliposomal and newer liposomal formulations, for MMS. METHODS: A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. The MEDLINE, PubMed, and EMBASE databases were queried for articles presenting original data on the use of bupivacaine for MMS. RESULTS: Of 483 potentially relevant articles, 3 studies met final inclusion criteria, capturing a total of 253 patients involved in primary investigations comparing bupivacaine to traditional local anesthesia for MMS. Bupivacaine was well-tolerated and associated with comparable or modestly reduced intraoperative and postoperative pain and opioid use. CONCLUSION: Bupivacaine may have a role in prolonging intraoperative anesthesia, reducing acute postoperative pain, and reducing postoperative opioid use after MMS. However, large, prospective studies are needed to solidify the generalizability and clinical utility of these findings.
