Comparative Study of 1444 nm Laser Monotherapy versus Integrated Liposuction in the Treatment of Axillary Osmidrosis.

Background and Objectives: The 1444 nm wavelength Neodymium:Yttrium-Aluminum-Garnet (Nd:YAG) laser treatment is an efficient method for treating axillary osmidrosis (AO); however, it has a relatively low treatment persistence. To address this issue, we performed integrated liposuction surgery with a laser to treat AO and compared the results with those of a group treated only with a laser. Materials and Methods: This study compared the outcomes of AO treatment between the two groups up to six months postoperatively. The first group of 18 patients underwent laser treatment alone, and the second group of 12 patients underwent integrated liposuction surgery in addition to laser treatment. Outcomes were assessed using the following variables: degree of malodor (DOM), sweating area, patient satisfaction, pain levels, and complications, such as burns, swelling, and contractures. Results: Compared to the laser-only group, the integrated liposuction group demonstrated significantly superior outcomes in terms of DOM (p = 0.002) and patient satisfaction (p = 0.006), as well as a reduction in the sweating area (p = 0.012). The pain rating was higher in the liposuction group, but the difference was not statistically significant (p = 0.054). Compared with the patients in the integrated liposuction treatment group, those in the laser treatment group exhibited a significantly higher number of burns under the axillae (p = 0.025). However, no significant differences were observed in the swelling or contracture between the groups. Conclusions: Integrated liposuction with laser therapy significantly improved treatment outcomes, including malodor, patient satisfaction, sweat test results, and decreased complication rates.

Clinical efficacy of microwave in the treatment of axillary osmidrosis and primary hyperhidrosis.

Axillary osmidrosis (AO) and primary hyperhidrosis (PH) are common diseases, but there are still difficulties in treatment. Microwave therapy may become a new method. In order to evaluate long-time efficacy of patients with AO or PH treated by microwave and to discuss possible mechanism of microwave therapy by combining results of clinical and pathological, the study was carried out. Ten AO or PH patients with moderate or severe level were selected as subjects, and each subject received microwave treatment of bilateral armpits. The follow-up period lasted 2 years, and the changes of perspiration and odor were evaluated in subjective and objective ways. Each subject took skin biopsy in the treatment area before and after treatment or each follow-up. Hematoxylin-eosin and immunohistochemical staining were performed. Both subjective and objective index reflected the significant improvement of AO and PH after treatment (p < 0.05). Dermatology life quality index score decreased by 10.4 ± 4.6 (p < 0.05). The number of apocrine glands decreased significantly after treatment, and most of them changed from secretory phase to quiescent phase. In conclusion, microwave therapy can destroy apocrine sweat glands, reduce number of functional glands, so as to improve symptoms of AO and PH and elevate quality of life, which is safe, effective, and stable.

Power-assisted rotary cutter with negative pressure suction through small incision for axillary osmidrosis.

BACKGROUND: The glandular fluid secreted by apocrine sweat glands is decomposed by parasitic bacteria on the skin surface and releases a bad smell called axillary osmidrosis. OBJECTIVE: To evaluate the effect of power-assisted rotary cutter with negative pressure suction through small incision for axillary osmidrosis. METHODS: From January 2017 to January 2022, 647 patients with axillary osmidrosis underwent power-assisted rotary cutter with negative pressure suction through small incision surgery to treat for axillary osmidrosis. The operation time (min), intraoperative bleeding (ml) and recovery time (days) were counted. Three months after operation, the amount of underarm sweat, the disappearance of underarm hair, the incidence of operation, the effective rate of operation, and the satisfaction of operation results were evaluated by questionnaire. RESULTS: There were no postoperative complications except five cases of mild axillary pigmentation after 3 months. All patients evaluated good odor elimination. No patient was rated as average or poor. No recurrence. CONCLUSION: Power-assisted rotary cutter with negative pressure suction through small incision is an effective and ideal surgical method to reduce the complications and recurrence of axillary osmidrosis.

Efficacy of topical acidified aliphatic ester for treatment of axillary osmidrosis by rebalancing skin microecology.

This study investigated the mechanism and efficacy of topical acidified aliphatic ester for treatment of axillary osmidrosis (AO). A total of 32 AO patients were enrolled in this study. In the initial pilot study, 20 patients were double-blindly, randomly divided into acidified aliphatic ester or aliphatic ester treatment groups, followed by efficacy evaluation after 4 weeks. Then, all patients (n = 32) were treated with topical acidified aliphatic ester for 16 weeks. Efficacy was evaluated at every 4 weeks, and at 3- and 6-month follow-ups. Changes of pH values and microecology at targeting sites were analyzed. In the first cohort (n = 20) of pilot study, acidified aliphatic ester showed significantly higher curative rate (60% vs 10%, P < .05) and effective rate (90% vs 30%; P < .05) than aliphatic ester. For the next 16 weeks, 25 of 32 cases completed treatment. Curative rate showed gradual and significant increases from 64% to 96% during the treatment courses (P = .001); it slightly but insignificantly decreased at 3- and 6- month follow-ups. Abundance of Corynebacterium and Anaerobic bacteria decreased while Staphylococcus increased after treatments. Axillary pH values negatively correlated with Staphylococcus abundance (r = -.40, P = .01) and positively with Corynebacterium abundance (r = .64, P = .01). We concluded that topical acidified aliphatic ester could effectively alleviate conditions of AO patients by reducing value of axillary pH and rebalancing axillary microecology.

Comparison of Effectiveness and Associated Complications Between Conventional Subdermal Excision and Hydrosurgery (VersajetTM) for Osmidrosis.

BACKGROUND: Recent studies have shown hydrosurgery (Versajet TM II) is a simple and effective tool with reduced complications in surgical treatment of osmidrosis. Since then, hydrosurgery has been widely used for osmidrosis. However, we have experienced that some complications often occur in patients treated with hydrosurgery. OBJECTIVE: We hypothesized that using a hydrosurgery could lead to excessive resection of the tightly attached apocrine glands and thus more complications. We aimed at evaluating the effectiveness and associated complications of the hydrosurgery method for osmidrosis were compared with those of conventional methods with two parallel incisions. METHODS & MATERIALS: We retrospectively analyzed 31 and 16 patients who underwent conventional and hydrosurgery methods, respectively, for osmidrosis from 2010 to 2020. Two parallel long incisions were identical in both groups. Early complications (hematoma, seroma, wound dehiscence, skin necrosis, revision, scar contracture), late complications (scar, pigmentation, comedones/milia, and sebaceous cysts), and effectiveness (subjective satisfaction, malodor elimination, reduced hair growth, and sweating elimination) were evaluated. RESULTS: Skin necrosis was significantly more frequent in the hydrosurgery group than in the conventional group (p = 0.036). No other significant differences were found between the two groups in terms of other complications and effectiveness. As a result of comparing effectiveness, subjective satisfaction (p = 0.306), malodor elimination (p = 1.000), reduced hair growth (p=1.000), and sweating elimination (p = 0.742) did not show any significant difference between the two groups. CONCLUSION: Osmidrosis treatment with the use of VERSAJET™ Hydrosurgery System yielded similar and satisfactory results as the conventional subdermal excision method. The incidence of skin necrosis was higher in the hydrosurgery group than in the conventional group with two parallel incisions.

Percutaneous Interstitial Nd:YAG Laser Therapy for Axillary Osmidrosis.

BACKGROUND AND OBJECTIVES: To investigate the effects of percutaneous interstitial Nd:YAG laser irradiation on the apocrine glands and molecules involved in odor production (apolipoprotein [ApoD], androgen receptor [AR]) in the subcutaneous tissue of a pig. STUDY DESIGN/MATERIALS AND METHODS: Skin on the back of healthy adult miniature pigs was exposed to pulsed Nd:YAG laser irradiation at 5 or 10 W, or continuous Nd:YAG laser irradiation at 10 W. Samples were taken 1 hour, 1 week, and 1 month after treatment for histology, western blot, and real-time quantitative polymerase chain reaction (qRT-PCR) analysis. RESULTS: One week and 1 month after irradiation, the apocrine glands in pigskin became rounded, glandular cells were shorter, and the glandular cavities were larger compared with controls, but there were no obvious changes in fat cell distribution of collagen around the apocrine glands. One month after irradiation at 10 W in continuous mode, there was a significant decrease in ApoD expression in apocrine cells and ApoD and AR protein and expression levels in pigskin compared with controls. There were also significant differences in ApoD and AR protein and expression levels between treatments. CONCLUSIONS: Percutaneous interstitial Nd:YAG laser irradiation has potential as a safe and efficacious treatment for axillary osmidrosis as it may decrease the production of volatile unsaturated fatty acids, steroids, and associated unpleasant odors in the axilla.

Silver nitrate: a novel therapeutic approach for refractory Seroma following body malodor surgery.

Seroma, a fluid collection that can develop after surgery, can be a challenging complication to manage. Conventional treatment options, such as quilting suture and drainage tubes, may not be effective in resolving refractory seromas. This article presents two cases of refractory seroma after axillary osmidrosis surgery that were successfully treated with silver nitrate. Silver nitrate, a topical agent with antiseptic, anti-inflammatory, and wound-healing properties, has been shown to be effective in treating perianal fistulas and persistent tracheocutaneous fistulas. In both cases presented here, silver nitrate resulted in complete seroma resolution within 7 and 14 days, respectively. This study suggests that silver nitrate may be a promising treatment option for refractory seroma after axillary osmidrosis surgery. Further research is warranted to validate these findings and establish optimal dosage and treatment protocols.

Functional characterization of variants in human ABCC11, an axillary osmidrosis risk factor.

Human ATP-binding cassette transporter C11 (ABCC11) is a membrane protein exhibiting ATP-dependent transport activity for a variety of lipophilic anions including endogenous substances and xenobiotics such as anti-cancer agents. Accumulating evidence indicates that ABCC11 wild type is responsible for the high-secretion phenotypes in human apocrine glands including wet type of earwax and the risk of axillary osmidrosis. Also, a less-functional variant of ABCC11 was reportedly associated with a risk for drug-induced toxicity in humans. Thus, functional change in ABCC11 may affect individual's constitution and drug toxicity, which led us to reason that functional validation of genetic variations in ABCC11 should be of importance. Therefore, in addition to p.G180R (a well-characterized non-functional variant of ABCC11), we studied cellular expression and function of 10 variants of ABCC11. In this study, ABCC11 function was evaluated as an ATP-dependent transport of radio labeled-dehydroepiandrosterone sulfate using ABCC11-expressing plasma membrane vesicles. Except for p.G180R, other 10 variants were maturated as an N-linked glycoprotein and expressed on the plasma membrane. We found that six variants impaired the net cellular function of ABCC11. Among them, p.R630W was most influential. Including this identification of a significantly-dysfunctional variant, our findings will extend our understanding of genetic variations and biochemical features of ABCC11 protein.

Effect of optimizing the use of endoscope on the efficiency of microdynamic bromhidrosis removal operation.

BACKGROUND: Bromhidrosis, also known as body odor, is a common disease in life, which often occurs in young adults. The histological basis of bromhidrosis is the hyperplasia of apocrine sweat glands. OBJECTIVE: To compare the effects of different methods of endoscopy in microdynamic axillary osmidrosis removal on curative effect, complications, and surgical efficiency. METHODS: A total of 149 patients with axillary osmidrosis were treated in our hospital from January 2020 to December 2021. They were treated with endoscopic assistance in the whole process of operation (Group A) and endoscope-assisted exploration after blind rotary cutter suction (Group B), respectively, and the curative effect, complication rate, and surgical efficiency were evaluated. RESULTS: There was no significant difference in the curative effect and complication rate between the two groups, but the endoscope-assisted exploration group after suction with rotary cutter (Group B) had higher surgical efficiency. CONCLUSION: On the basis of professional use of rotary cutter, it is efficient to choose endoscope to check the excision of sweat gland in the operation area and stop bleeding in time after blind suction.

Minimally invasive 1,444-nm Nd:YAG laser treatment for axillary bromhidrosis.

Background: Axillary bromhidrosis is an apocrine glands hyperactivity disease. Methods: A total of 24 patients (15 men and 9 women) with axillary bromhidrosis underwent a laser procedure with a 1,444-nm Nd:YAG laser. Parameters evaluated in this study were as follows: the degree of malodor (T0, baseline; T30, after 1 month; and T180, after 6 months), postoperative pain, short-term decreased mobility (T1, after 1 day; T7, after 7 days; and T30, after 1 month), and overall satisfaction (T30, after 1 month and T180, after 6 months). A visual analog scale (VAS), from 0 to 10, was used to assess pain and decreased mobility, with lower values denoting less severity. Results: A total of 24 patients were followed up for 6 months after laser treatment. At baseline, all patients (100%) complained of a strong axillary malodor (mean degree of malodor at T0 = 2.0 ± 0.00). It decreased to 0.50 ± 0.64 at T30. At T180, the degree of malodor was 0.54 ± 0.57. Both T30 and T180 degrees of malodor significantly decreased from the baseline value (p < 0.01). The mean degree of patient satisfaction at T30 was 1.75 ± 0.52, and at T180, it was 1.67 ± 0.21. Among the 24 patients, eight complained of moderated pain 1 day after treatment. The pain subsided on day 7, except for two patients, with VAS = 1. Pain and mobility restrictions were in any case resolved within T30. Conclusion: Treatment with a 1,444-nm Nd:YAG laser for subdermal interstitial coagulation could be a less invasive and more effective option treatment for axillary bromhidrosis.

Long-Term Use of Antiperspirant is Associated with a Low Risk of Postoperative Complications in Patients with Axillary Osmidrosis.

Purpose: Many patients with axillary osmidrosis (AO) cannot tolerate the local irritation of strong antiperspirants and discontinue AO use within a short time. This study evaluates the effect of long-term antiperspirant use on postoperative complications after osmidrosis surgery. Patients and Methods: A total of 116 females (66 antiperspirant and 50 non-antiperspirant cases) who underwent osmidrosis surgery were retrospectively reviewed. Postoperative complications were compared between the 2 groups. Results: Patients with long-term antiperspirant use had a lower risk of full-thickness skin necrosis compared with those who did not use antiperspirants (odds ratio [OR] = 0.048, 95% confidence Interval [CI]: 0.006-0.392, p = 0.005). Patients with antiperspirants use also had a lower risk of moderate-to-severe erythema compared to those without antiperspirants use (moderate vs mild erythema: OR = 0.351, 95% CI: 0.129-0.959, p = 0.041; severe vs mild erythema: OR = 0.161, 95% CI: 0.047-0.550, p = 0.004). Patients who used antiperspirants also had a lower risk of severe skin erosion compared to those who did not use antiperspirants (severe vs mild skin erosion: OR = 0.164, 95% CI: 0.037-0.725, p = 0.017). There was a trend of lower risk in moderate skin erosion in patients with antiperspirant use compared to those without antiperspirant use, but it was not statistically significant (moderate vs mild epidermal damage and peeling: OR = 0.406, 95% CI: 0.158-1.043, p = 0.061). Conclusion: Postoperative complications in patients with AO who undergo osmidrosis surgery are lower in those with a long-term antiperspirant use compared to patients who did not use antiperspirants.

Treatment of Axillary Osmidrosis by Rebalancing Skin Microecology With Lactobacillus bulgaricus.

Corynebacterium accounts for around 20% of the armpit microbiome and plays an essential role in axillary osmidrosis (AO). In this study, the effects of Lactobacillus bulgaricus treatment on the microecological environment of armpits and its efficacy in the treatment of AO were investigated. A total of 10 AO patients were enrolled in this study. The patients were treated with L. bulgaricus mixed with saline on the left armpit (experimental group) and pure saline on the right armpit (control group) for 28 days. After treatment, AO severity showed a significant decrease (p = 0.013) in the experimental group compared with the control group, and the Corynebacterium abundance also showed a corresponding significant decrease (p < 0.01). Moreover, no significant variation in Staphylococcus abundance was found between these two groups. The microbe diversity is not disturbed in the treatment. Accordingly, our study demonstrates that L. bulgaricus can serve as an effective probiotic microbe for AO treatment by reducing the abundance of Corynebacterium and rebalancing the microecological environment.

A retrospective study on comparing the surgery and microneedles radiofrequency and microwaves treatment in axillary osmidrosis.

OBJECTIVE: To compare the traditional treatment of minimally invasion surgery with the evolving treatments of microneedles radiofrequency and microwaves, this study mainly focused on the clinical efficacy and the incidence rate (IR) of complications among three treatments. METHODS: From August 2017 to August 2018, a total of 76 patients with bilateral axillary osmidrosis were enrolled respectively underwent minimally invasion surgery, microneedles radiofrequency and microwaves treatment. All these subjects were evaluated the clinical outcomes and collected the complications by themselves or physicians. The difference of objective recovery or effective rate, subjective effective rate, the intense of sweat secretion or armpits hair, IR of complications among these three groups were studied. RESULTS: The baseline characteristics of 33 patients in surgery group, 24 patients in microneedles group and 19 patients in microwaves group were similar. Firstly, the objective clinical efficacy was similar, but the subjective effective rate in surgery group was the soundest. In addition, the reduction of sweat secretion was homologous in three group, but the intense of armpits hair reduction in microneedles group was the minimum in three groups. Moreover, surgery treatment caused the highest IR of complications and the broadest types of complications, especially for the IR of 87.9% in postoperative scar formation. Meanwhile, the microwaves treatment had the best safety profile. At last, the recurrence rate on 6 months postoperatively was also identical with no significant difference. CONCLUSIONS: For the advantages and disadvantages of these three treatments, axillary osmidrosis patients should choose the proper therapy with comprehensive considerations.

Association of BMI and lipid profiles with axillary osmidrosis: a retrospective case-control study.

BACKGROUND: Axillary osmidrosis (AO) is a common disease. There are no safely effective therapies for AO. OBJECTIVE: The objective of our study was to establish whether increased BMI and lipid profiles affects the prevalence of AO. METHODS: Our research was a retrospective case-control study. According to our criteria, 203 patients with AO were included in our study and 94 subjects with no bromhidrosis were matched as the control group. Age, ethnicity, living area, level of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), and body mass index (BMI) were obtained from the clinical data. Logistic regression analysis and multivariate Cox regression analysis were used to investigate the association of BMI and lipid profiles with AO. RESULTS: BMI, TC, and TG LDL were significantly higher in patients with AO compared with control subjects (p<.05). A high BMI (≥24 kg/m2) or overweight, compared with a low BMI (<24 kg/m2) or normal, was associated with an increased risk of AO (OR: 6.1; 95% CI: 2.7, 13.4; p<.0001). Adjustment of the lipid profiles' group has a higher risk of disease than unadjusted (OR: 56.4 compared with 6.1, respectively), while adjusting lipid profiles shows a lower risk than unadjusted (OR: 1.3 compared with 6.1, respectively). CONCLUSIONS: The results of our study revealed that increased BMI is significantly associated with the prevalence of AO.

An innovative technique of hydrosurgery in the treatment of osmidrosis.

BACKGROUND: We aimed at evaluating the effects of hydrosurgery and traditional surgical approach with two parallel incisions in the treatment of osmidrosis. METHODS: This prospective study enrolled patients with axillary osmidrosis between January 2015 and November 2016. For hydrosurgery, a 1-cm-long incision was made in the middle of the posterior long axis. The hand piece was turned upside down and processed in a 'W-O' way. For traditional method, two 3-cm-long parallel incisions were made transversely. Patient demographics, complications, duration of procedures and the outcomes were collected and compared. All patients had a follow-up period of 24-36 months. RESULTS: A total of 93 patients were included: 41 patients in hydrosurgery group and 52 patients in traditional method group. No severe complications occurred in the hydrosurgery group, while necrosis occurred in six sides of axillae of traditional surgical group. No recurrence occurred in both groups. Both groups showed similar odor and hair growth reduction rate. Only one in 82 sides occurred slight scar formation, while in traditional group, 22 sides of axillae formed scars (p < .001). CONCLUSIONS: The application of hydrosurgery in the treatment of osmidrosis is efficient and effective. Moreover, it has less postoperative complications, and high patient satisfaction rates.

The Modified Suction-curettage Technique for Minimally Invasive Treatment of Axillary Osmidrosis.

BACKGROUND: Axillary osmidrosis (AO) is a common and nonnegligible disease, the treatment of which is currently lacking a consensus. AIMS: The aim of this study was to introduce a modified suction-assisted technique as a safer and more efficient surgical procedure. METHODS: This retrospective clinical study included 80 patients who recieved a modified suction-curettage procedure (group A) or a subcutaneous gland excision procedure (group B). Intraoperative assessment (endoscopy and pathological biopsy) and postoperative assessment (complications, therapeutic effect, and satisfaction) were performed for both groups. RESULTS: The endoscopy and pathological biopsy results demonstrated that the modified suction-curettage technique could remove the apocrine gland efficiently. Compared with group B, a lower complication rate (long-term, 5.00%; P=0.014, and short-term, 11.10%; P=0.001) and higher patient satisfaction (98.00%, P=0.012) were observed in group A. CONCLUSION: The modified suction-curettage procedure is an effective and safe treatment for axillary osmidrosis.

Open versus Closed Surgery for Axillary Osmidrosis: A Meta-Analysis of Articles Published in Four Languages.

BACKGROUND: Individuals with axillary osmidrosis suffer detrimental effects to their psychosocial functioning. In Asian nations, major operations for axillary osmidrosis include subdermal excision (open surgery) and suction-curettage (closed surgery). OBJECTIVE: The aim of this meta-analysis was to determine which of these two procedures is most favorable in terms of safety and efficacy. METHODS: According to the Preferred Reporting Items for Systematic Reviews and Metaanalyses (PRISMA) guideline, we searched electronic databases for articles published in English, Japanese, Korean, and Chinese languages. Fixed-effects model meta-analyses of odds ratios (OR) and 95% confidence intervals (CI) were conducted, and the I2 was used to assess heterogeneity. Complication rates, recurrence/ineffectiveness rates, and patient satisfaction data were extracted and compared between open and closed surgeries. RESULTS: Our search yielded 8 articles that include 1,179 patients; 560 underwent open surgery, and 619 underwent closed surgery. Our meta-analysis revealed that suction-curettage had a significantly lower risk of acute adverse events than open excision (OR, 0.15; 95% CI, 0.07~0.32), whereas open excision was significantly superior to suction-curettage for recurrence/ineffectiveness rate (OR, 2.90; 95% CI, 1.37~6.15). Patient satisfaction was equally high with both treatments (OR, 1.58; 95% CI, 0.69~3.60). CONCLUSION: Since surgical treatments for axillary osmidrosis have been performed mostly in East Asian nations, it was meaningful to review articles published in four languages. This meta-analysis revealed that closed surgery was safer but less effective than open surgery. However, both patient groups expressed high satisfaction with the outcomes. Our results may be helpful for deciding surgical treatment options.

Hidden Blade Scalpel: A Useful Tool for the Treatment of Axillary Osmidrosis.

BACKGROUND: Axillary osmidrosis is a distressing problem that can particularly affect a patient's social life. In severe cases, patients may seek a surgical treatment to achieve a permanent effect. Many treatment techniques involving destruction or removal of the apocrine and eccrine glands have been developed. However, previous treatments have been hindered by surgical or aesthetic concerns. The purpose of this study was to evaluate the effect of the hidden blade scalpel procedure in treating axillary osmidrosis. METHODS: From December 2012 to December 2016, 372 patients with axillary osmidrosis underwent the hidden blade scalpel procedure. One 5-mm incision was made at approximately 1 cm beyond the axillary hairline. A hidden blade scalpel was then used to remove the subcutaneous tissue, including the plexus, apocrine and eccrine glands, and hair follicles, from the skin. The clinical efficacy was evaluated using a questionnaire. RESULTS: The hidden blade scalpel procedure resulted in a high percentage of patient satisfaction, a much shorter recovery time, and a low complication rate. CONCLUSION: The hidden blade scalpel procedure is an effective method for the treatment of axillary osmidrosis.
