Robotic ramicotomy for palmar and axillary hyperhidrosis

Multimed Man Cardiothorac Surg. 2026 Mar 4;2026. doi: 10.1510/mmcts.2025.150.

ABSTRACT

Ramicotomy is a surgical approach that focuses on dividing the rami communicantes of the sympathetic chain and has been introduced as a treatment for palmar and axillary hyperhidrosis with the goal of reducing the incidence of compensatory sweating. Evidence from recent randomized controlled studies and meta-analyses suggests that this technique effectively reduces localized excessive sweating while resulting in lower rates of compensatory hyperhidrosis and less postoperative hand dryness compared with traditional sympathetic chain interruption. Despite these advantages, ramicotomy has been linked to a greater likelihood of symptom recurrence, underscoring the importance of thorough patient selection and detailed preoperative counseling about potential long-term outcomes. Overall quality of life improvements and patient satisfaction appear similar between ramicotomy and conventional sympathicotomy, although ramicotomy may provide benefits in decreasing the severity or extent of compensatory sweating. In cases of axillary hyperhidrosis, combining ramicotomy with endoscopic sympathetic blockade does not seem to significantly change patient satisfaction or overall rates of compensatory sweating compared with blockade alone, though it may influence the pattern or distribution of compensatory symptoms. In summary, ramicotomy is a reasonable surgical option for carefully selected patients who prioritize a lower risk of compensatory hyperhidrosis, accepting the trade-off of a potentially higher recurrence rate.

The role of acupuncture in managing hyperhidrosis and vasomotor sweating: evidence, mechanisms, and gaps

Complement Ther Med. 2026 Feb 27:103337. doi: 10.1016/j.ctim.2026.103337. Online ahead of print.

ABSTRACT

BACKGROUND AND PURPOSE: Hyperhidrosis and thermoregulatory disorders, including menopausal and treatment-induced hot flushes, can significantly impair quality of life. While acupuncture has been proposed as a potential non-pharmacological treatment for these conditions, the quality and consistency of available evidence remain unclear. This review aims to critically assess the current literature on acupuncture for various kinds of hyperhidrosis, evaluating its clinical efficacy, mechanisms of action, and limitations.

METHODS: A narrative review was conducted based on English-language, PubMed-indexed published clinical studies, randomised controlled trials (RCTs), and meta-analyses investigating acupuncture as a treatment for primary hyperhidrosis, emotional sweating, paraneoplastic sweating, and hot flushes in both menopausal and breast cancer populations. Particular attention was paid to study quality, intervention protocols, and outcome durability.

RESULTS: Evidence for the use of acupuncture in primary, emotional, and paraneoplastic hyperhidrosis is limited to small, often uncontrolled studies with significant methodological shortcomings. In contrast, acupuncture for menopausal and breast cancer-related hot flushes is supported by multiple RCTs and meta-analyses involving over 1,000 participants, demonstrating short-term improvements in frequency and severity of symptoms. However, effects on hot flushes generally diminish after three months post-treatment. Mechanistically, acupuncture is thought to act via modulation of the autonomic nervous system and neuropeptide regulation, though precise pathways remain to be fully elucidated.

CONCLUSION: Acupuncture may offer short-term benefits for hot flushes in menopausal and breast cancer populations, but current evidence for its effectiveness in other kinds of hyperhidrosis remains weak and inconclusive. High-quality, standardised clinical trials with long-term follow-up are needed to better define its role in the integrative management of thermoregulatory disorders.

Early onset, genital, and axillary involvement are strongly associated with impaired quality of life in hyperhidrosis patients

Medicine (Baltimore). 2026 Feb 20;105(8):e47698. doi: 10.1097/MD.0000000000047698.

ABSTRACT

Hyperhidrosis is a chronic condition marked by excessive sweating that significantly affects patients’ quality of life (QoL). However, this issue is both underrecognized and undertreated, and its physical, emotional, and social burdens are often underestimated, particularly in Middle Eastern populations. A cross-sectional, analytical study was conducted across Saudi Arabia between May 2024 and April 2025. Participants were recruited through dermatology clinics and a Telegram support group. They completed an online self-administered Arabic questionnaire regarding demographics, medical history, the Arabic Hyperhidrosis Disease Severity Scale, and the Hyperhidrosis Quality of Life Index. A total of 276 Arabic-speaking adults with hyperhidrosis participated. The mean age was 27.3 years (SD ± 8.2), and 57.6% of the respondents were male. Most participants (82.9%) had severe hyperhidrosis (Hyperhidrosis Disease Severity Scale grades 3-4). The mean HidroQoL scores were 10.3 out of 14 for daily life and 16.6 out of 22 for psychosocial life, indicating moderate to severe burden. Disease severity showed the strongest association with QoL impairment (P = .001). Other factors significantly associated with daily functioning included lower education level, lower income, and sweating in the axillae and genital region, while genital involvement and low education were associated with psychosocial distress. Hyperhidrosis imposed a substantial QoL burden, especially in patients with severe symptoms and lower socioeconomic status. The findings supported the need for early detection and tailored treatment strategies and the use of culturally validated patient-reported outcome measures like the Arabic HidroQoL in clinical practice.

Oxf Med Case Reports. 2026 Feb 18;2026(2):omag001. doi: 10.1093/omcr/omag001. eCollection 2026 Feb.

ABSTRACT

Aquagenic palmoplantar keratoderma is a rare dermatological condition characterized by mild palmar thickening and burning pain upon exposure to water. A 31-year-old female with aquagenic keratoderma of the palms associated with palmoplantar hyperhidrosis presenting with wrinkling and hyperkeratosis within minutes of hand contact with water, resolving quickly after drying. While cystic fibrosis is a known association, most cases remain idiopathic. Treatment options such as 20% aluminum hydroxide, aluminum chloride (15%-20%), urea, salicylic acid, and botulinum toxin can be challenging, with the patient being evaluated after treatment with 16% aluminum chloride.

Hospital-Based Tap Water Iontophoresis for Primary Focal Hyperhidrosis: A Real-World Analysis of Treatment Adherence, Efficacy, and Relapse

J Clin Med. 2026 Jan 13;15(2):640. doi: 10.3390/jcm15020640.

ABSTRACT

Background: Tap water iontophoresis (TWI) is a well-established second-line treatment for primary focal hyperhidrosis. While its efficacy is proven, data regarding the correlation between session frequency and clinical response, as well as long-term adherence in hospital-based settings, remain limited. Objective: We aimed to evaluate the efficacy and safety of hospital-based TWI and to analyze the relationship between the number of treatment sessions and clinical outcomes. Methods: This retrospective study included 92 patients with primary focal hyperhidrosis treated with TWI. Disease severity was assessed using the Hyperhidrosis Disease Severity Scale (HDSS). Clinical response was categorized as “Excellent” (≥2-point HDSS reduction), “Good” (1-point reduction), or “No Response.” Relapse rates and reasons for treatment discontinuation were analyzed over a 6-month follow-up period. Results: The overall objective response rate was 65.2% (46.7% Excellent, 18.5% Good). A significant positive correlation was found between the total number of treatment sessions and the degree of clinical response (r = 0.401, p < 0.001). Patients achieving an “Excellent” response completed a significantly higher median number of sessions compared to non-responders (p = 0.001). However, among responders, the relapse rate was 85% within six months. Logistical difficulties were the most common reason for treatment discontinuation (17.5%). No compensatory hyperhidrosis or severe adverse events were observed. Conclusions: Hospital-based TWI is a safe and highly effective induction therapy, with success rates closely linked to the number of completed sessions. However, the high relapse rate and logistical barriers to adherence suggest that hospital-based protocols should serve primarily as a bridge to home-based maintenance therapy to ensure sustained long-term remission.

A significant gap between inadequate pharmacotherapy and substantial unmet needs in palmar hyperhidrosis management in China: insights from a questionnaire-based survey among outpatients

Front Pharmacol. 2026 Jan 8;16:1715189. doi: 10.3389/fphar.2025.1715189. eCollection 2025.

ABSTRACT

BACKGROUND: Palmar hyperhidrosis, characterized by excessive sweating primarily affecting the hands, significantly impairs quality of life and psychological well-being. Although topical agents, iontophoresis, microwave therapy, and sympathectomy are established interventions, real-world treatment patterns and pharmacotherapeutic adequacy among Chinese patients remain poorly delineated.

METHODS: An anonymous, questionnaire-based survey was conducted among consecutive patients at a tertiary thoracic surgery clinic in China between March 2023 and October 2024. A total of 363 valid responses were collected and analyzed using SPSS 27.0. Descriptive statistics and multivariable logistic regression were used to evaluate treatment patterns, patient preference, and predictors of treatment selection.

RESULTS: The study cohort was composed predominantly of individuals with severe disease (87.3% HDSS grade 3-4), and nearly all participants (97.8%) presented with palmar hyperhidrosis. Regarding treatment history, only 38.1% had previously received pharmacotherapy, while 32.6% had utilized Traditional Chinese Medicine (TCM) therapeutic approaches, including TCM, acupuncture, massage and manipulation therapies. Antiperspirants (28.6%) and TCM (25.0%) were the most frequently used prior pharmacotherapies, yet both were associated with limited therapeutic efficacy. According to our survey, owing to high symptom severity, 52.9% had a general knowledge of surgical intervention before the outpatient visit. Primary concerns regarding previous pharmacotherapy included insufficient efficacy and localized adverse effects, particularly skin irritation. Notably, 50.0% of participants remained receptive to future pharmacotherapy, showing a preference for topical formulations (29.3%) and reduced dosing frequency (31.6%). Gender and disease severity were identified as significant determinants of treatment choice. Importantly, prior negative experiences – such as inefficacy and side effects – did not significantly diminish willingness to consider future pharmacologic treatment.

CONCLUSION: Inadequate management and suboptimal treatment outcomes represent considerable challenges in the care of palmar hyperhidrosis in China. Existing pharmacotherapeutic options are constrained by limited availability, inadequate efficacy, and a narrow range of approved agents – a reality that highlights a critical disconnect with substantial patient demand. These findings underscore an urgent need to accelerate drug development and clinical translation in this field.

Hyperhidrosis: Prevalence, Diagnosis, and Stepwise Treatment

Dtsch Arztebl Int. 2026 May 1;(Forthcoming):arztebl.m2025.0229. doi: 10.3238/arztebl.m2025.0229. Online ahead of print.

ABSTRACT

BACKGROUND: Hyperhidrosis, or sweating beyond the physiological amount, can be either focal or generalized and sometimes runs in families. The prevalence of primary idiopathic hyperhidrosis is 2-5%. Secondary hyperhidrosis is associated with specific illnesses and medications. In this article, we discuss the diagnostic evaluation of hyperhidrosis and treatments for it, along with their efficacy and side effects.

METHODS: This narrative review is based on publications retrieved from the Medline and Cochrane databases with the search term “hyperhidrosis” and other specific terms relating to treatment. Expert recommendations and guidelines were considered as well.

RESULTS: The diagnostic evaluation consists of a clinical history, a Minor (starch-iodine) test, gravimetry, and dynamic sudometry. There have been no more than a few high-quality published studies on specific interventions. Depending on the severity and symptom burden, aluminum chloride and anticholinergic drugs are used first, followed by botulinum toxin injections and subcutaneous curettage for axillary hyperhidrosis. These treatments reportedly bring about marked improvement in 60-70 % of patients; their side effects, depending on the particular treatment used, include local reactions such as itch, pain, and cutaneous irritation and anticholinergic effects such as dry mouth, mydriasis, urinary retention, and headache. Further therapeutic options are tap water iontophoresis; radiofrequency, focused ultrasound, and microwave treatment; systemically administered anticholinergic drugs; and thoracic or lumbar sympathectomy for palmar or plantar hyperhidrosis, respectively.

CONCLUSION: A variety of methods can be used to relieve hyperhidrosis and improve these patients’ quality of life. There have been no more than a few high-quality studies on their efficacy and long-term results.

Botulinum Toxin Type A in the Treatment of Primary Axillary Hyperhidrosis:A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study of Efficacy and Safety in Chinese Patients

Aesthet Surg J. 2026 Jan 19:sjaf260. doi: 10.1093/asj/sjaf260. Online ahead of print.

ABSTRACT

BACKGROUND: The efficacy and safety of botulinum toxin type A (BoNTA) treatment for primary axillary hyperhidrosis (PAH) have not been explored in the Chinese population.

OBJECTIVES: The objective was to evaluate efficacy and safety of 1 intradermal BoNTA injection in Chinese PAH cases.

METHODS: This was a Phase 3, multicenter, randomized, double-blind, placebo-controlled study. Patients were randomized to an experimental group or the control group at a ratio of 3:1 and received either BoNTA or a placebo once. The primary efficacy endpoint was the proportion of patients who experienced an over 50% reduction in axillary sweat weight at Week 4 posttreatment compared to baseline. The key secondary efficacy endpoints were the percentage changes in axillary sweat weight at Weeks 1, 4, 8, and 16 posttreatment.

RESULTS: A total of 344 patients were randomized to the experimental group (n = 258) or the control group (n = 86). The proportions of patients who experienced an over 50% reduction in axillary sweat weight at Week 4 posttreatment were 83.72% (216/258) in the experimental group and 55.81% (48/86) in the control group, respectively. The between-group difference was 27.91% (P < .001). BoNTA treatment yielded a significant reduction in axillary sweat weight, hyperhidrotic area, hyperhidrosis disease severity scale (HDSS) scores, and grade of bromhidrosis. The patients in the experimental group reported significantly higher satisfaction scores than those in the control group. BoNTA treatment was well tolerated. Neither group experienced suspected unexpected serious adverse reactions, or adverse events or adverse drug reactions leading to withdrawal or death.

CONCLUSIONS: One intradermal 50-U BoNTA treatment led to a significant reduction in axillary sweat weight, axillary hyperhidrotic area, HDSS scores, and axillary bromhidrosis grades in Chinese PAH patients. The therapeutic effect was maintained for 16 weeks posttreatment, with a favorable safety profile.
