Abstract
Botulinum toxin (BoNT) has been known for over 50 years. It has conquered many areas of medicine and has become indispensable in contemporary medicine. Now, BoNT is used to treat at least 26 conditions in six medical specialties. Although the use of BoNT began in strabology, it became the gold standard for many ophthalmologic pathologies. The present review of the literature focuses on the use of BoNT in ophthalmology and treatment of the following conditions: blepharospasm, facial hemispasm, facial palsy, spastic entropion, strabismus, endocrine orbitopathy, convergence spasm, and facial trauma. We conclude that nearly half a century of experience in utilizing BoNT in ophthalmology ensured a satisfactory level of effectiveness and safety for patients with many pathologies. Areas of future research include the application of BoNT in new selected indications, the development of the route of application without injections, and the development of long-acting BoNT forms for patients who require repeated long-term treatment.

[PMID: 37365738 DOI: 10.3349/ymj.2022.0605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 04/29/2023] [Accepted: 05/08/2023] [Indexed: 06/28/2023] Open
Abstract
PURPOSE Understanding the muscle actions and resultant skin movement can enable more safe and effective botulinum toxin injection for the treatment of forehead wrinkles. We aimed to investigate skin displacement patterns of the forehead and adjacent skin due to frontalis muscle contraction using three-dimensional skin vector displacement analysis. MATERIALS AND METHODS Thirty healthy individuals were enrolled. Photographs of the face were taken at rest and during maximal contraction of the frontalis muscle. Each expression image was aligned to its respective static image to compute the differences in the skin position. RESULTS When frontalis muscle contracts, forehead skin displacement vectors were mostly vertical (63.4%), followed by lateral oblique (33.3%) and medial oblique (3.3%). In 53.3%, only the lower part of the forehead moved upward, while 40.0% showed bidirectional skin movement with transition line at a mean distance of 59.4 mm above the pupil. Moreover, 86.7% showed asymmetric skin displacement, and 83.3% showed both glabellar and eyebrow skin displacement. Frontalis muscle contraction also induced medial 2/3 (50.0%) or entire (33.3%) skin movement of the temple. CONCLUSION Botulinum toxin injection into the forehead can be individualized by considering the vector and asymmetry of skin displacement. Vertical or medial vector requires more centrally located injections, while laterial vector requires more laterally located injections. The presence and location of the vertical transition line are important for preventing ptosis when treating forehead lines with botulinum toxin. Glabellar movement during frontalis contraction suggests the need for a concomitant injection into the glabella to prevent glabella wrinkle accentuation.

Abstract
BACKGROUND Currently, botulinum toxin (BoNT) injections are the most commonly performed non-invasive procedure for rejuvenation on the upper face. The therapeutic use of botulinum toxin has generally been safe and well tolerated. Adverse effects are considered mild, transient, and self-limited. However, as with all other injectable procedures, this one is also susceptible to adverse events and complications. When the safety zones are respected, the chance of any of these complications is practically null. Thus, this review aims to describe the main complications of treatment with BoNT on the upper face and to present a practical guide based on current evidence on how to avoid them. METHODS The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles. RESULTS The main complications secondary to BoNT injections on the upper face are: ptosis of eyelid or eyebrow, eyebrow asymmetry, diplopia, Lakeophthalmos, Palpebral ectropion, and prominence of the palpebral bags. To avoid such complications, it is necessary to have knowledge of the anatomy of this region and adequate and individualized planning based on the existing patterns of the frontalis muscle, glabella, and crow's feet. This review presents the specificities of each of these regions and practical suggestions to obtain satisfactory results, avoiding complications. CONCLUSION Particularly on the upper face treatment with BoNT offers predictable results, has few adverse effects, and is associated with high patient satisfaction. However, it is suggested that the commented parameters and safety areas be incorporated into daily practice so that the possibilities of complications are minimized as much as possible.

Abstract
BACKGROUND Botulinum toxin is used in the treatment of headache as well as cosmetic indications. In recent years, headache cases have been encountered after botulinum toxin injections for cosmetic purposes. However, no clinical studies have been conducted on this seemingly paradoxical issue. OBJECTIVE In our study, the aim was to evaluate the frequency of occurrence of headache and its clinical features in patients who had undergone botulinum toxin application for cosmetic purposes. METHODS A total of 186 patients who were treated with onabotulinum toxin A for cosmetic purposes in our clinic between January 2019 and January 2021 were retrospectively screened, and the clinical and demographic characteristics of the patients who reported headache complaints were examined. RESULTS Headache was reported in 19 (10.2%) of the 186 patients included in the study. Of the 19 patients who reported headaches, 17 (89.4%) had the onset of the complaint within the first 24 h, the complaint was resolved within the first 3 days in 16 (84.2%), and 12 (63.1%) reported spontaneous regression without the need for painkillers. The rate of development of headache complaints after the procedure was found to be statistically significantly higher in patients diagnosed with hypertension (p = 0.000) and patients treated for bunny line (p = 0.016). Ten patients (52.6%) described constant, 17 patients (89.5%) had diffuse, and 11 patients (57.9%) had throbbing-type headaches. CONCLUSION Botulinum toxin application causes diffuse, constant, throbbing-type headaches that start in the early period and ends within a short time without the need for treatment.

Abstract
Background Botulinum toxin A (BoNT‐A) has grown tremendously in aesthetic dermatology since 2002 when the United States Food and Drug Administration (FDA) first approved its use for treating moderate‐to‐severe glabellar lines. Blepharoptosis, due to local spread of toxin, is a reported side effect of BoNT‐A which, although rare, more frequently occurs among inexperienced practitioners. Objectives The purpose of this review is to highlight the causes and management of eyelid ptosis secondary to BoNT‐A administration including new anatomic pathways for BoNT‐A spread from the brow area to the levator palpebrae superioris muscle. Methods A literature search was conducted using electronic databases (PubMed, Science Direct, MEDLINE, Embase, CINAHL, EBSCO) regarding eyelid anatomy and the underlying pathogenesis, presentation, prevention, and treatment of eyelid ptosis secondary to BoNT‐A. Anatomic dissection has been performed to assess the role of neurovascular pedicles and supraorbital foramen anatomic variations. Results Blepharoptosis occurs due to weakness of the levator palpebrae superioris muscle. Mean onset is 3–14 days after injection and eventually self‐resolves after the paralytic effect of BoNT‐A wanes. Administration of medications, such as oxymetazoline hydrochloride or apraclonidine hydrochloride eye drops, anticholinesterase agents, or transdermal BoNT‐A injections to the pre‐tarsal orbicularis, can at least partially reverse eyelid ptosis. Anatomic study shows that a supraorbital foramen may be present in some patients and constitutes a shortcut from the brow area directly into the orbital roof, following the supraorbital neurovascular pedicle. Conclusion Providers should understand the anatomy and be aware of the causes and treatment for blepharoptosis when injecting BoNT‐A for the reduction of facial wrinkles. Thorough anatomic knowledge of the supraorbital area and orbital roof is paramount to preventing incorrect injection into “danger zones,” which increase the risk of eyelid ptosis.

Abstract
BACKGROUND Botulinum toxin A can be used to eliminate dynamic wrinkles by relaxing the muscles involved in facial expressions. Therefore, it is essential to know the location, origin, insertion, function, and changes of the facial expression muscles according to their contraction. METHODS After drawing the muscles on the face of a model, pictures were taken at rest. The model was then asked to make facial expressions that cause facial wrinkles. All images were taken with the Vectra H1 camera system (Canfield Scientific, Inc., Fairfield, New Jersey). Each expression image was aligned to its respective static image to compute the differences in skin position, so as to calculate the skin displacement vectors. The values for local changes in skin displacement were calculated by applying the automated algorithms of the Vectra Software Mirror Suite and visualized using the color and size of the arrow. RESULTS Face painting and 3D skin vector displacement analyses enabled visualization of all the facial muscles involved in facial expressions working dynamically, allowing us to visualize the effect of each muscle in the creation of hyperkinetic wrinkles. Face painting and 3D skin vector displacement analyses can be combined to determine the location of the wrinkles, extent of the muscle, part of the muscle that contracts, presence of asymmetry, direction in which the muscle contracts, and correlation between the antagonists and synergistic muscles. CONCLUSION The botulinum toxin A injection educational model using body painting and 3D skin vector displacement analyses can provide a deeper understanding of actual moving muscle anatomy.

Abstract
BACKGROUND Botulinum toxin A (botulinum toxin A) was found to provide a wide variety of therapeutic and aesthetic benefits as one of the most potent toxins in the world. Injectable remedies, including soft tissue fillers and botulinum toxin, have become very common in wrinkling and face rejuvenation management. While these methods of treatment are relatively safe, serious side effects can occur. In this review, the complications of BoNTA are highlighted. METHODS A literature research considered published journal articles (clinical trials or scientific reviews). Electronic databases (PubMed, Scopus, Science Direct) were searched using key terms, and for identification of additional relevant studies, reference lists have also been examined. Only articles published in English were included in this review with a time restriction from 2000 to 2020. RESULTS There are various injection-related adverse effects associated (AE) with botulinum toxins such as erythema, oedema, pain, ptosis of eyelid or brow and ecchymosis. The overall majority of adverse events identified are mild and temporary. CONCLUSION As the use of toxins becomes increasingly more common, adverse events can be expected to increase as well. The practitioners need to be aware of such AEs, and the patients should be informed of these before undertaking such procedures.

Abstract
Botulinum toxin is one of the most potent molecule known to mankind. A neurotoxin, with high affinity for cholinergic synapse, is effectively capable of inhibiting the release of acetylcholine. On the other hand, botulinum toxin is therapeutically used for several musculoskeletal disorders. Although most of the therapeutic effect of botulinum toxin is due to temporary skeletal muscle relaxation (mainly due to inhibition of the acetylcholine release), other effects on the nervous system are also investigated. One of the therapeutically investigated areas of the botulinum neurotoxin (BoNT) is the treatment of pain. At present, it is used for several chronic pain diseases, such as myofascial syndrome, headaches, arthritis, and neuropathic pain. Although the effect of botulinum toxin in pain is mainly due to its effect on cholinergic transmission in the somatic and autonomic nervous systems, research suggests that botulinum toxin can also provide benefits related to effects on cholinergic control of cholinergic nociceptive and antinociceptive systems. Furthermore, evidence suggests that botulinum toxin can also affect central nervous system (CNS). In summary, botulinum toxin holds great potential for pain treatments. It may be also useful for the pain treatments where other methods are ineffective with no side effect(s). Further studies will establish the exact analgesic mechanisms, efficacy, and complication of botulinum toxin in chronic pain disorders, and to some extent acute pain disorders.

Abstract
Botulinum neurotoxin (BoNT) is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines, or crow's feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use. BoNT has gained widespread use in a variety of ophthalmic diseases. The effect of BoNT is temporary, but the therapeutic benefit is usually maintained even after repeated injections. Treatment is usually well tolerated. Complications and side effects associated with the treatment are rare and temporary. Complications occur due to weakness (chemodenervation) of adjacent muscle groups, immunological mechanisms and injection technique. Current therapeutic indications, doses, complications and contraindications of BoNT use in the following disorders related to ophthalmology were investigated: aesthetic use, strabismus, blepharospasm, hemifacial spasm, eyelid retraction, entropion, lacrimal hypersecretion syndrome, and facial paralysis.

Abstract
The authors report the case of a 65-year-old, right-hand-dominant man who had severe Dupuytren's disease with multiple cords and flexion contractures of the metacarpophalangeal and proximal interphalangeal joints of both hands and underwent repeated collagenase injections for treatment. Collagenase has been shown to be safe and effective in the treatment of Dupuytren's contractures when administered as a single dose, but the results of multiple injections over a prolonged period are unknown. Antibodies to collagenase develop in all patients after several treatments, raising concerns about safety and efficacy as a result of sensitization from repeated exposures. The antibodies generated as a result of repeated exposure to collagenase could theoretically render it less effective with time and could also lead to immune reactions as severe as anaphylaxis. The authors present the case of a single patient who experienced continued correction of his contractures with only minor and self-limited adverse reactions after administration of 12 collagenase doses through 15 injections during a 4-year period. Over time, the injections continued to be effective at correcting metacarpophalangeal joint contractures, but less effective at correcting proximal interphalangeal joint contractures. The patient did eventually require a fasciectomy, but the safety and modest success of the repeated collagenase injections shows promise for a less invasive treatment with a better risk profile than open fasciectomy. Although further studies are needed, repeated administration of collagenase appears to be safe and modestly effective for severe Dupuytren's contractures, although a fasciectomy may ultimately be required in the most severe cases.

Abstract
We describe a patient who received cosmetic botulinum toxin type A injections to the brow and subsequently developed unilateral ptosis that was variable during examination and was transiently improved after the ice pack test. Ptosis gradually resolved spontaneously over approximately 3 months. This is the third patient to have variable ptosis documented after botulinum toxin type A injection to the brow and the second to have a positive ice test. The ice test is not completely specific for myasthenia gravis but may, at times, improve ptosis resulting from other defects at the neuromuscular junction. Wound botulism now is much more common because of illicit drug use, and the ice test also might be positive in this setting.

Abstract
Over the past decade, facial rejuvenation procedures to circumvent traditional surgery have become increasingly popular. Office-based, minimally invasive procedures can promote a youthful appearance with minimal downtime and low risk of complications. Injectable botulinum toxin (BoNT), soft-tissue fillers, and chemical peels are among the most popular non-invasive rejuvenation procedures, and each has unique applications for improving facial aesthetics. Despite the simplicity and reliability of office-based procedures, complications can occur even with an astute and experienced injector. The goal of any procedure is to perform it properly and safely; thus, early recognition of complications when they do occur is paramount in dictating prevention of long-term sequelae. The most common complications from BoNT and soft-tissue filler injection are bruising, erythema and pain. With chemical peels, it is not uncommon to have erythema, irritation and burning. Fortunately, these side effects are normally transient and have simple remedies. More serious complications include muscle paralysis from BoNT, granuloma formation from soft-tissue filler placement and scarring from chemical peels. Thankfully, these complications are rare and can be avoided with excellent procedure technique, knowledge of facial anatomy, proper patient selection, and appropriate pre- and post-skin care. This article reviews complications of office-based, minimally invasive procedures, with emphasis on prevention and management. Practitioners providing these treatments should be well versed in this subject matter in order to deliver the highest quality care.

Abstract
PURPOSE Lateral internal sphincterotomy has been the gold standard treatment for chronic anal fissure, but it still carries the risk of permanent damage of the anal sphincter, which has led to the implementation of alternative treatment like botulinum toxin injection. The aim of this randomized prospective controlled trial was to compare the efficacy and morbidity of botulinum toxin injection and lateral internal sphincterotomy in the treatment of chronic anal fissure. METHODS Fifty consecutive adults with chronic anal fissure were randomly treated with either lateral internal sphincterotomy or botulinum toxin (BT) injection with 50 U BT into the internal sphincter. The complications, healing and recurrence rate, and incontinence score were assessed 2, 3, 6, 12 months after the procedure. RESULTS Inspection at the 2-month visit revealed complete healing of the fissure in 11 (44 %) of the patients in the BT group and 22 (88 %) of the patients in the lateral internal sphincterotomy (LIS) group (p = 0.001). At the 3-month visit, there was no significant difference between the two groups in healing. The overall recurrence rate after 6 months in the BT group was higher than in the LIS group (p < 0.05). In the 3-month follow-up, the LIS group had a higher rate of anal incontinence compared to the BT group (p < 0.05). The final percentage of incontinence was 4 % in the LIS group (p > 0.05). CONCLUSIONS The treatment of chronic anal fissure must be individualized depending on the different clinical profiles of patients. Botulinum toxin injection has a higher recurrence rate than LIS, and LIS provides rapid and permanent recovery. However, LIS carries a higher risk of anal incontinence in patients.

Abstract
OBJECTIVE To analyse systematically prospective randomized controlled trials dealing with the effectiveness of surgical sphincterotomy (SS) vs chemical sphincterotomy (CS) using botulinum toxin for the management of chronic anal fissure (CAF). METHOD A systematic review of the literature was undertaken. Prospective randomized controlled trials on the effectiveness of SS vs CS using botulinum toxin were selected and analysed to generate the summative outcome. RESULTS Four prospective randomized controlled trials dealing with SS vs CS using botulinum injection, which included 279 CAF patients, were analysed. Based on the random effects model, there was a higher complication rate [Risk ratio (RR) 14.54 (-9.84, -38.9) 95% CI, df = 2, P < 0.0163] and a higher risk of transient faecal incontinence [RR 6.39 (-2.37, -15.1) 95% CI, df = 3, P < 0.0001] in the SS group than in the CS group. However, there was significant heterogeneity among the trials (Q = 8 408 891, P < 0.0001), indicating a wide confidence interval range; thus, the inferiority of SS could not be shown. SS had a significantly higher healing rate [RR 1.63, (1.34-1.91) 95% CI, df = 3, P < 0.0110] and a significantly lower recurrence rate [RR 0.35 (0.33-0.38) 95% CI, df = 3, P < 0.0221] than CS. CONCLUSION Both CS and SS are comparable in the management of CAF. There are no differences in the complication rates and incontinence rates between the two procedures. SS has a higher healing rate and a lower recurrence rate than CS. As long as the patient is willing to accept a negligible risk of transient faecal incontinence, SS should be the first-line treatment for CAF.

Abstract
BACKGROUND Focal hyperhidrosis is not rare, affecting over 2.5% of the population. This condition is often socially and professionally debilitating, leading to significant quality of life impairment. It most commonly involves the axillae, palms, soles, and face. OBJECTIVE To review hyperhidrosis and discuss and compare the treatment options currently available. CONCLUSIONS Topical or systemic therapies may be helpful for patients with mild disease. Invasive surgical options, although often effective, are limited by complications. More recently, botulinum toxin injection has proven to be a safe and successful treatment for hyperhidrosis and results in high patient satisfaction. Botulinum toxin A (Botox, Allergan Inc., Irvine, CA) is currently approved in the United States, Canada, the United Kingdom, and many other countries for the treatment of axillary hyperhidrosis and is routinely used off-label for other anatomic sites.

Abstract
OBJECTIVE The objective was to identify the cause of an asymmetrical smile and to ascertain whether or not it would be correctable by injections of Botulinum toxin A (BTX-A). METHODS Five patients with asymmetrical smiles were identified and found to lower one side of their lower lip in an exaggerated fashion when smiling or laughing. After close observation, it was determined that the ipsilateral depressor labii inferioris of the lower lip was hyperkinetic and retracted that side of the lips lower than its contralateral side when smiling or laughing. Injections of low-volume and low-dose BTX-A (BOTOX, Allergan, Inc.) were placed into the depressor labii inferioris on the side where the lower lip retracted the lowest. RESULTS All of the five patients with asymmetrical smiles presented with unilateral hyperkinetic depressor labii inferioris and responded to injections of BOTOX. Their lower lips became level and their smiles were symmetrical within 1 week of the BOTOX treatments. Their lip symmetry lasted for at least 6 months after their initial treatment. With each additional treatment, the duration of BOTOX lasted even longer, averaging approximately 7 months. CONCLUSION BOTOX is an effective, safe, and long-lasting treatment for lower lip asymmetries caused by a hyperkinetic depressor labii inferioris.

Abstract
Scalp injection of botulinum toxin type A (BT-A) into the superficial musculature has evoked interest in the management of migraine headache. In clinical trials, prevention of migraine attacks for 3 months or more has been seen in some patients following BT-A scalp injections. In the majority of pain syndromes where BT-A is effective, inhibition of muscle spasms appears to be an important component of its activity. A direct or independent and prolonged analgesic action unrelated to skeletal muscle relaxation is believed to underlie the prophylactic efficacy of BT-A in migraine; peripheral and central modulation of pain impulses by BT-A has also been proposed. A direct peripheral antinociceptive effect was not seen in three controlled studies of BT-A in normal human volunteers. Experimental evidence for BT-A-induced analgesia in rats is suggestive but dose-dependent and lasts only 2 weeks. In migraine patients, a consistent or dose-dependent response to BT-A treatment has not been seen. Peak responses to BT-A in migraine patients are seen at 8-12 weeks, whereas BT-A-affected nerve endings in mice fully recover function between 63 and 91 days; the difference in species limits the interpretation of this dissonance. As BT-A does not normally cross the intact blood-brain barrier, meningeal nociceptors appear unlikely to be influenced by scalp injections of BT-A; the possibility of antidromic transfer of BT-A in the trigeminovascular system should be considered. The extended period for which migraine prophylaxis might be required, the antigenic and headache-provoking potential of BT-A, the inability of BT-A to affect central neuronal processes significantly, including the aura of migraine, the possible placebo effect of needling, and purely subjective outcome measures in headache studies are additional concerns in evaluating this treatment strategy. The clinical utility of BT-A has not been compared against established migraine prophylactic agents. The efficacy of BT-A in preventing migraine headache attacks remains controversial and the underlying scientific rationale is debatable.

Abstract
Botulinum toxin (BTX) is a potent neurotoxin produced by Clostridium botulinum and has wide usage in different areas. The current study aimed to analyze the effects of C. botulinum toxin on the central nerve system in chick embryos. Forty fertile Hubbard Broil eggs, all at Stage 8 of development, were divided into four equal groups: Group 1 embryos (n=10), the control group, were explanted and grown for 18 h in a nutrient medium (thin albumin). Group 2 embryos (n=10) were grown in medium containing 5 U BTX, Group 3 embryos (n=10) in a medium containing 10 U BTX and Group 4 embryos (n=10) in medium containing 20 U BTX. After the incubation period, 80% of Group 1 and 2 embryos and 90% of Group 3 and 4 embryos had intact neural tubes (P>0.05). The results of this study suggest that BTX had no additional effect on neural tube development in early chick embryos.

Abstract
INTRODUCTION Proctalgia fugax can be defined as transitory but recurrent anal pain. Although its etiology remains unknown, an internal anal sphincter spasm seems to be the most likely, so that the different treatments focus on reducing the pressure of the internal anal sphincter. This study is aimed at evaluating the effectiveness of botulinum A toxin in the treatment of proctalgia fugax. PATIENTS AND METHODS Prospective clinical trial of patients with proctalgia fugax treated with botulinum A toxin at the Outpatient Clinic attached to the Coloproctogy Unit, University Hospital of Elche, from January 1999 to January 2002. The patients included in the study underwent rectal digital examination, anuscopy, rectoscopy, anal manometry and ultrasonography, barium enema and pelvic CT scan to rule out any organic cause for anal pain. The treatment consisted of 25 IU of botulinum A toxin, with a supplementary dose of 50 IU in those patients with persistence of anal pain episodes within the next two months. The patients were reviewed on the first week, second month, sixth month and first and second year. Anal pain was measured by the patients, using a linear analogue scale from 0 to 10, and continence was assessed at every visit using the Cleveland Continence Grading Scale. RESULTS Five patients were recluted for the study, with a predominance of females (4 vs. 1). Mean age was 45 years. Length of symptoms prior to the treatment was 13 months (range: 6-18 months). Only one female patient required a second dose of botulinum A toxin to handle the anal pain. All the patients healed and remained free of pain up to finishing the follow-up. There were no local complications. Anal manometry showed an increased MRP (mean resting pressure) in comparison to a control group of patients (114 mmHg vs. 66 mmHg; p < 0.001) that restore to normal values after the treatment (75.65 mmHg). As for the MSP (mean squeeze pressure), it showed no difference with respect to the control group nor did it vary after the treatment. CONCLUSION Botulinum A toxin offers a high rate of healing with no associate morbidity in the treatment of proctalgia fugax.

Abstract
The role of botulinum toxin in facial rejuvenation has been greatly expanded in the last several years. In this article, we first review the traditional approach to botulinum toxin therapy in the forehead and glabella. For the advanced reader, we then discuss both the literature and our personal approaches to treatments of the periocular region, mid face, lower face, and neck. Throughout the discussion, attempts are made to include a description of relevant anatomy, the physiologic result of specific muscle activity and denervation, and perhaps most importantly, precise directions for patient treatment.

Abstract
A pivotal point in most clubfoot management protocols is Achilles tendon lengthening or tenotomy to address hindfoot deformity. The effectiveness of botulinum A toxin (BTX-A) in attenuating the function of the triceps surae muscle complex as an alternative to tenotomy was investigated. Fifty-one patients with 73 idiopathic clubfeet were recruited. Outcome measures included surgical rate, Pirani clubfoot score, ankle dorsiflexion with knee in flexion and extension, and recurrences. Patients were divided according to age: group 1 (<30 days old) and group 2 (>30 days and <8 months old). Ankle dorsiflexion in knee flexion and extension remained above 20 degrees and 15 degrees, respectively, and Pirani scores below 0.5 following BTX-A injection for both groups. One of the 51 patients required limited posterior release and 9 patients required repeat manipulation and casting plus or minus BTX-A injection. The use of BTX-A as an adjunctive therapy in the noninvasive approach of manipulation and casting in idiopathic clubfoot is a safe and effective treatment.

Abstract
PURPOSE : Botulinum neurotoxins are considered relatively safe therapy for treatment of inappropriate muscle spasms. As seen in this report, undesirable consequences may result. METHODS : The author conducted a clinical interview and examination of the patient. RESULTS : Unilateral left-sided madarosis and facial alopecia were observed in a patient undergoing botulinum A toxin injections for the treatment of left oromandibular dystonia. The patient had started treatment 18 months previously. He received injections every 3 months in the left masseter and left temporalis muscles. He first noted loss of his left sideburn 8 months into treatment. After 10 months of treatment, he noted that he no longer needed to shave on the left side of his face. Eighteen months after receiving his first botulinum toxin injection, madarosis of the temporal aspect of the left lower lid was observed. CONCLUSIONS : This is the first case report documenting an idiosyncratic unilateral madarosis and facial alopecia as adverse side effects presumed secondary to botulinum A toxin injections.

Abstract
BACKGROUND Masseteric muscle hypertrophy is an uncommon dition represented as a swelling of the masseter muscle. Recent reports have demonstrated the successful use of botulinum in the treatment of masseteric hypertrophy. OBJECTIVE This study was a prospective trial to evaluate the effectiveness of botulinum toxin type A (Botox) in the treatment of masseteric muscle hypertrophy according to doses of 10, 20, and 30 U. MATERIALS AND METHODS Twenty-two patients were referred to the dermatologic clinic for the management of masseteric muscle hypertrophy. Ultrasonographic measurements of the thickness of the masseter muscle were performed, and clinical photographs were taken before treatment and 1, 2, 3, 4, 6, and 9 months after the treatment. RESULTS. The median values of percentage reduction of muscle mass were 10.3%, 16.5%, 23.7%, 24.7%, 21.6%, 16.5% in the 10 U group; 11.9%, 18.8%, 24.8%, 27.7%, 26.7%, and 21.8% in the 20 U group; and 12.0%, 19.4%, 25.0%, 27.8%, 37.8%, and 24.1% in the 30 U group. CONCLUSION. The adequate dose of botulinum toxin type A for treatment of masseteric muscle hypertrophy should be above 20 U. The effect of botulinum toxin type A is maintained for at least 9 months as the treatment of masseteric muscle hypertrophy.

Abstract
BACKGROUND AND OBJECTIVE The aim of this prospective randomized trial was to compare the effectiveness and morbidity of surgical vs chemical sphincterotomy in the treatment of chronic anal fissure after a 3-year follow-up period. PATIENTS AND METHOD Eighty patients with chronic anal fissure were treated either with close lateral internal sphincterotomy (group 1) or with chemical sphincterotomy with 25 U botulinum toxin injected into the internal sphincter (group 2). RESULTS Overall healing was 90% in the close sphincterotomy group and 45% in the toxin botulinum group (p < 0.001). There was a group of patients with clinical factors (duration of disease over 12 months and presence of a sentinel pile before treatment) associated with a higher recurrence of anal fissure. Final percentage of incontinence was 5% in the close sphincterotomy group and 0% in the botulinum toxin group (p > 0.05). All incontinent patients were aged more than 50 years. CONCLUSIONS We recommend surgical sphincterotomy as the first therapeutic approach in patients with clinical factors of recurrence. However, we recommend the use of botulinum toxin in patients older than 50 years or with associated risk factors of incontinence, despite the higher rate of recurrence, since it avoids the greater risk of incontinence seen with surgery.

Abstract
INTRODUCTION AND AIM To evaluate the effectiveness of botulinum toxin in the treatment of chronic anal fissure after long-term follow-up and establish the manometric factors related to recurrence. PATIENTS AND METHOD We performed a prospective study in 50 consecutive patients with chronic anal fissure who were treated with 25 U botulinum toxin injected into the internal sphincter. Clinical and manometric parameters were recorded until the fourth year of follow-up. RESULTS There was a tendency to progressive recurrence over time (54% at 4 years) associated with manometric factors indicating hyperexcitability of the internal anal sphincter (persistently elevated mean resting pressure, percentage of time with slow waves, and number of patients or percentage of time with ultra-slow waves after treatment). CONCLUSIONS Treatment of chronic anal fissure with botulinum toxin leads to long-term cure in less than 50% of patients. In patients with manometric factors related to recurrence, this treatment is insufficient for definitive cure.

[PMID: 15820455 DOI: 10.1016/j.amjsurg.2004.06.045] [Citation(s) in RCA: 82] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2004] [Revised: 06/13/2004] [Accepted: 06/13/2004] [Indexed: 10/25/2022]
Abstract
BACKGROUND The aim of this prospective randomized trial was to compare the effectiveness and morbidity of surgical versus chemical sphincterotomy in the treatment of chronic anal fissure after a 3-year follow-up. METHODS Eighty patients with chronic anal fissure were treated by whether open lateral internal sphincterotomy (group 1) or chemical sphincterotomy with 25 U botulinum toxin injected into the internal sphincter (group 2). Clinical and manometric results were analyzed. RESULTS Overall healing was 92.5% in the open sphincterotomy group and 45% in the toxin botulinum group (P<.001). There is a group of patients with clinical (duration of disease >12 months and presence of a sentinel pile before treatment) and manometric factors (persistently elevated mean resting pressure, % of time presence of slow waves, and number of patients or the time presence ultra slow waves after treatment) associated with a higher recurrence of anal fissure. The final percentage of incontinence was 5% in the open sphincterotomy group and 0% in the botulinum toxin group (P>.05). CONCLUSION We recommend surgical sphincterotomy as the first therapeutic approach in patients with clinical and manometric factors of recurrence. We prefer the use of botulinum toxin in patients older than 50 years or with risk factors for incontinence, despite the higher rate of recurrence, since it avoids the greater risk of incontinence in the surgical group.

Abstract
BACKGROUND The aim of this prospective trial was to analyse the effectiveness and morbidity of chemical sphincterotomy in the treatment of chronic anal fissure after a 3-year follow-up. METHODS One hundred consecutive patients with chronic anal fissures were treated by chemical sphincterotomy with 25 U botulinum toxin injected into the internal sphincter. Clinical and manometric results were recorded. RESULTS No major complications were found; initial incontinence at the 2-month review (6%) spontaneously reversed at 6 months. There was a tendency of progressive recurrence over time, with an overall healing after 3 years of 47%. We found a group of patients with clinical (symptoms longer than 12 months and presence of a sentinel pile before treatment) and manometric factors (persistently elevated mean resting pressure, percentage of time with slow waves, and number of patients or percentage of time with ultra slow waves after treatment) associated with a higher recurrence of anal fissures. CONCLUSION Since it avoids the greater risk of incontinence associated with surgical sphincterotomy, we recommend the use of botulinum toxin as the first therapeutic approach for patients with chronic anal fissure and risk factors for incontinence; despite the higher rate of recurrence associated with this treatment. In patients with factors related to recurrence, re-injection with higher doses of botulinum toxin or complementary medical-surgical treatment should be considered.

Abstract
The use of botulinum toxin type A (BTX-A) for facial rejuvenation was first systematically developed by Carruthers and Carruthers on the upper aspect of the face. In the early 1990s, the first studies of the cosmetic use of BTX-A were published. BTX-A was only approved in 2002, however, by the U.S. Food and Drug Administration when extensive cosmetic studies were evaluated. The treatment of facial wrinkles with BTX-A has truly changed the concepts held by physicians regarding facial rejuvenation, mainly on the upper aspect of the face. It is one of the most common cosmetic procedures currently performed by physicians.

Abstract
Botulinum toxin type A (BOTOX, Dysport) has revolutionized treatment of wrinkles around the eyes. Since the first publications of its cosmetic benefit by Drs. Jean and Alastair Carruthers, hundreds of articles have been published about its cosmetic use. BOTOX holds U.S. Food and Drug Administration approval in the United States for treatment of glabellar lines. BOTOX is in widespread use worldwide and is currently the most popular cosmetic treatment in the United States.

Abstract
BACKGROUND An injection of the lateral canthus and infraorbital fold is commonly used to soften wrinkles and widen the eye. OBJECTIVE To illustrate a case report of festooning and to hypothesize as to its cause. METHODS A 56-year-old man developed festooning of the infraocular area after injection of botulinum toxin A. RESULTS Prior lower lid blepharoplasty with separation of the infraorbital orbicularis oculi muscle may have weakened the muscle enough to cause festooning with further weakening of the muscle through botulinum toxin A injection. CONCLUSION Caution must be exercised when performing infraocular injection of botulinum toxin A in patients with prior transtarsal lower lid blepharoplasty.

Abstract
BACKGROUND It is recommended that botulinum toxin be used immediately or within 2 weeks after its reconstitution because its efficacy might be compromised by prolonged storage. OBJECTIVES To evaluate the efficacy of botulinum toxin type A (BTX-A) reconstituted over 6 consecutive weeks for the treatment of glabellar frown lines. METHODS Four vials of BTX-A were reconstituted each of 7 days over a period of 6 weeks, totaling 28 vials, corresponding to seven reconstitution dates. During this period, the BTX-A was stored according to the manufacturer's instructions. On the day after the last reconstitution, all of the reconstituted vials were injected in patients from four dermatologic centers taking part in this study. A total of 88 patients were treated on the same day and were followed every 2 weeks for 4 months. All patients were photographed at all stages. A number of professionals assessed the efficacy of reconstituted BTX-A based on the reduction of the maximum frowning capacity of the treated muscles. RESULTS Of the 88 patients who were selected, 3 were excluded. Three forms of evaluation were applied, and no statistically significant differences were found in the results presented. CONCLUSION BTX-A may be applied up to 6 weeks after reconstitution without losing its effectiveness. Other factors, which are probably individual, may influence the response to BTX-A injections.

Abstract
BACKGROUND Botulinum neurotoxin formulations are safe and effective agents for the treatment of facial rhytides. OBJECTIVES A patient is described who complained of metallic taste after each treatment with botulinum toxin A (BTX-A). RESULTS The sensation of metallic taste diminished after successive treatments with BTX-A, despite adequate dosing for cosmetic purposes. CONCLUSION Metallic taste is associated with the use of numerous medications; however, the pathogenesis remains unclear. Alteration in zinc metabolism, which may occur with BTX-A administration, has been suggested as a possible mechanism. Although this is the first known report of dysgeusia after BTX-A, physicians and patients may be reassured that the taste alteration was self-limited and was not significantly problematic for the patient in our case.
