Surgical smoke in Dermatology: Its hazards and management
Saloni Katoch, Venkataram Mysore

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):1-7

Surgical plume with vaporized tissue particles, pathogens, and toxic gases emanating during dermatosurgical procedures is an occupational hazard to the dermatosurgeon, and protective measures must be taken to prevent their inhalation. Smoke evacuators are devices that capture and filter the plume generated during electrosurgical procedures or laser procedures, thereby maintaining a safe environment for the surgical team and the patient. A smoke evacuation system should be appropriately selected depending on the need of the facility. The objective of this article is to outline the health hazards of the smoke by-product of electrosurgery and lasers and provide details about safety measures and smoke evacuation systems.

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):8-16

Laser hair removal since its availability has been primarily used for aesthetic purposes. Over the years, it has emerged as an important therapeutic modality in various dermatological and surgical disorders, both as an adjuvant and as a monotherapy. Depending on the skin type, all laser hair removal systems have been used with good results and minimal complications. We hereby review the diverse range of unconventional indications of laser hair removal.

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):17-24

Introduction: Halo nevus (HN) affects approximately 1% of the population. Presence of hypo- or depigmented lesion carries tremendous psychosocial disturbance in the mind-set of population in the Indian subcontinent. Hence, HN requires intervention by any modalities. Here authors attempted to evaluate the efficacy of monochromatic excimer light (MEL) in treating HN. Materials and Methods: A total of 29 patients with HN were included in the study. A xenon chloride lamp emitting noncoherent, monochromatic 308-nm light that represents the natural evolution of the excimer laser was used. The initial dose was 100 mJ/cm2, which was increased by 100 mJ/cm2 per session. All the patients were followed up for 6 months. Results: A total of 29 patients with 10 males and 19 females (male to female ratio of 1:1.9) completed the study. The age of onset of HN ranged from 5 to 47 years and the mean age of the patients was 23 years. HN was seen on the face, back, neck, chest, trunk, and extremities in 5 (17.2%), 6 (20.7%), 4 (13.7%), and 6 (20.7%) patients, respectively. Outstanding response was noticed in 14 patients (48.2%), whereas 6 (20.6%) patients showed excellent improvement. Only 2 (6.8%) patients showed no response after 10 consecutive sessions. Conclusion: HN causes apprehension in the Indian population because of the social stigma associated with depigmented patches on the body. Mere observation and only counseling in the treatment protocol are not sufficient. MEL is a noninvasive procedure, which results in excellent repigmentation of HN without scarring.

Context: Pincer nail deformity is a transverse overcurvature of the nail. Though various conservative and surgical techniques have been described in the literature, very few studies are based on objective measurements. This study was undertaken to evaluate the outcome of three-flap technique in the management of pincer nail. Aim: To study the outcome of three-flap technique in the management of pincer nail. Settings And Design: Prospective interventional study. Subjects and Methods: Fifteen patients with pincer nail deformity, fulfilling inclusion and exclusion criteria were enrolled for the study. Routine X-ray was carried out for all patients to detect underlying bony abnormalities such as exostoses. Width and height indices were calculated before the procedure. A three-flap technique was performed on all affected toe nails and outcome was assessed at the end of 6 months and 1 year. Statistical Analysis Used: Paired t-test and P value. Results: Satisfactory cosmetic outcome and statistically significant improvement (P < 0.0001) were achieved in all patients. Conclusions: Three flap technique is an useful technique in the management of pincer nail.

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):31-35

Context: Hair restoration surgery for androgenetic alopecia (AGA) essentially involves various forms of hair transplantation. There is paucity of studies assessing donor area in Indian men and also no simplified guidelines are available for the safe donor area for follicular unit extraction (FUE). Our study is an attempt to study the donor area in Indian men.Aims: To assess the density of follicular units (FUs) in the donor area, that is, both scalp and beard in Indian men, and to propose simplified guidelines for FUE.Materials and Methods: The study design was cross-sectional and was carried out for 2 years. All the consenting male patients with male pattern hair loss Hamilton Norwood grading III or more who consulted for a hair restoration surgery were recruited. FU density was assessed in the donor area of scalp by drawing a rectangle with its lower border being a straight line joining two points, which are 27–28mm from the line drawn perpendicular to tragus, passing through external occipital protuberance. Three squares of area 1cm2 were drawn within the rectangle. Average of the FUs and follicles in the three squares was calculated to obtain mean density in the donor area of the scalp. Total number of FU was assessed, considering 25% extraction, total average number of extractable follicles was assessed. Total donor area was divided into three areas (areas 1, 2, and 3) and average number of extractable FU was assessed in each. Donor area in the beard, below the jawline, was divided into a triangle and rectangle. Average number of FU, total number of extractable FU was calculated similarly.Results: A total of 580 male patients were recruited in the study. Mean FU density in the scalp and beard was 78.2/cm2 and 49.7/cm2, respectively. The total available number of FUs for extraction in the areas 1, 2, and 3 and beard considering 25% extraction was 2064, 3097, 3612, and 824, respectively. We propose three types of donor areas in the scalp, namely, limited, standard, and extended donor area.

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):36-41

Background: Stability in vitiligo is an important concept in guiding patient management and a vital prerequisite before vitiligo surgery. Disease activity of vitiligo based on patient’s history is imprecise. It is practically impossible to perform biopsy from all lesions of vitiligo to ascertain stability. Dermatoscopy can be used to examine all clinical lesions in a patient of vitiligo. There is a need to validate many reported dermatoscopic findings for universal use. Aims: To analyze the significance of dermatoscopic findings in the activity of vitiligo and to devise a cutoff score for stable vitiligo. Materials and Methods: Dermatoscopic examination was performed in 85 patients clinically diagnosed with vitiligo. Six dermatoscopic parameters, namely, border, pigment network, perilesional hyperpigmentation, perifollicular pigmentation, satellite lesions, and micro-Koebner phenomenon (acronym: BPLeFoSK) were evaluated against Wood’s lamp findings as standard. Chi-square test was used to test association between categorical variables. Cutoff values for stability for these six parameters were plotted in receiver operating curve. Results: A total of 131 vitiligo lesions were analyzed with dermatoscopy. Absence of satellite lesions and absence of micro-Koebner phenomenon were the most sensitive parameters (96.7% and 100%, respectively). Sharp border and absent or reticulate pigment network within the vitiligo patch were the most specific findings (100% and 91.5%, respectively). Conclusion: A cutoff score of more than or equal to 1.5 using the “BPLeFoSK criteria” indicates stability in the vitiligo lesion.

Background: Androgenetic alopecia (AGA) is a non-scarring alopecia with a characteristic pattern in genetically predisposed men and women. Hormonal abnormalities namely hyperandrogenism, hair cycle defects, genetic predisposition, and follicular miniaturization have been implicated as the causative factors for AGA. Aim: To analyze women with patterned hair loss and correlate their clinical findings with the histopathology and biochemical parameters. Materials and Methods: Female patients between 18 and 45 years of age with a history of hair loss on the crown, temporal area, and recession of hairline were clinically examined. These patients were then subjected to histopathological examination, and on confirmation of diagnosis of female pattern hair loss (FPHL), they were included in the study. Their morning blood sample was taken on 3rd–5th day of the menstrual cycle for hormonal analysis. The study was carried out on 30 patients and 30 age- and sex-matched controls. Results: A statistically significant difference was observed between the mean values of dehydroepiandrosterone sulfate, prolactin, androstenedione, and free triiodothyronine of cases and controls. The most common histopathological finding in our study was an increase in the percentage of telogen hair. Conclusion: The biochemical findings in our study corroborate the role of hyperandrogenism as one of the major etiological factors in FPHL with the role of adrenal androgens being central, and therefore all female patients with FPHL should be evaluated for underlying hormonal imbalances. The role of histopathology in FPHL can be used as a prognostic marker.

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):49-51

Q-switched Nd:YAG laser remains the gold standard for tattoo removal, but still some tattoos are not completely removed in a specified period as desired by the patient. Herein, we present a case report of 23-year-old patient who came to the outpatient department for tattoo removal. The tattoo measured around 20cm × 18cm and was located on the back. Nine to 12 sessions of 1064-nm Q-switched Nd:YAG laser were planned at 4- to 6-week interval. After the completion of nine sessions, all the shades of the tattoo disappeared, but the lines persisted. A trial of increased laser energy and multiple-pass R20 treatment was performed, which rather increased the scarring and no improvement in tattoo clearance was noticed. We tried mini-punch skin excision for clearing the remnant tattoo lines. The tattoo was cleared successfully without significant scarring. Mini-punch skin excision is a very promising technique, similar to the follicular unit extraction technique of hair transplant, for tattoo removal of the patients who want immediate results as compared to lasers that take almost a year, provided the patient accepts the risk of scarring.

Journal of Cutaneous and Aesthetic Surgery 2019 12(1):52-55

Long-standing facial paralysis induces degenerative facial muscle changes on the involved side, thus making the individual seem older than their actual age. Furthermore, contralateral facial hypertrophy aggravates facial asymmetry (Sulamanidze MA, Fournier PF, Paikidze TG, Sulamanidze GM. Removal of facial soft tissue ptosis with special threads. Dermatol Surg 2002;28:367-71). The introduction of absorbable barbed thread has proved to be a good alternative for treating facial asymmetry. It also allows the association with other nonsurgical procedures, such as botulinum toxin use and/or dermal fillers in facial remodeling (Atiyeh BS, Dibo SA, Costagliola M, Hayek SN. Barbed sutures “lunch time” lifting: evidence-based efficacy. J Cosmet Dermatol 2010;9:132-41 and Kaminer MS, Bogart M, Choi C, Wee SA. Long-term efficacy of anchored barbed sutures in the face and neck. Dermatol Surg 2008;34:1041-7.). The aim of the treatment (threads) of the mid and lower third of the face was to promote the mechanical effect (lifting) and biological effect (neocollagenesis) with the improvement of the nasolabial folds, jaw, and jawbone contour.
