Evaluation of Blepharoptosis in Patients With Refractory Blepharospasm by VISA-Video Recordings, Idiosyncratic Expressions, Sensory Tricks, and Ancillary Procedures.

BACKGROUND: How to evaluate blepharoptosis concomitantly presented with refractory and uncontrollable blepharospasm? To date, there is a paucity of publications on the ideal evaluation methods. An innovative method-video recordings, idiosyncratic facial expressions, sensory tricks, and ancillary procedures (VISA)-is developed for preoperative evaluation, and the surgical outcomes are demonstrated. METHODS: A retrospective study using VISA for blepharoptosis evaluation was conducted on 51 patients with refractory blepharospasm. Based on the evaluation, patients underwent blepharoptosis correction simultaneously besides the selective myectomy and myotomy in situ of the eyelid protractors for blepharospasm. Preoperative and postoperative palpebral fissure height, margin reflex distance 1, ptosis severity, and levator function were assessed to identify the effectiveness of VISA. All the procedures were performed by the senior author C.-S.L. RESULTS: There were 42 patients diagnosed with essential blepharospasm and 9 patients with Meige syndrome. Forty-one patients (82/102 eyelids [80.4%]) had concomitant blepharoptosis and blepharospasm. Ptosis severity was mild in 21 eyelids (25.6%), moderate in 12 eyelids (14.6%), and severe in 49 eyelids (59.8%). Preoperative/postoperative (6 months) values of palpebral fissure height, margin reflex distance 1, and levator function were 4.70 ± 2.45 mm/8.35 ± 1.33 mm (P < 0.05), -0.30 ± 3.19 mm/3.73 ± 1.05 mm (P < 0.05), and 13.07 ± 2.56 mm/13.68 ± 2.34 mm (P < 0.05), respectively. Undercorrection and revision rate reported 9.8% and 3.7%, individually. CONCLUSIONS: VISA approach overcomes the difficulty of blepharoptosis assessment in patients with refractory blepharospasm. It provides useful preoperative information required for adequate blepharoptosis correction in blepharospasm surgery and yielded desirable outcomes.

Selective Myectomy and Myotomy In Situ for the Management of Refractory Blepharospasm in Meige Syndrome.

BACKGROUND: Meige syndrome is characterized by involuntary blepharospasm and varied subphenotypes of oromandibular tonic-clonic muscle contraction. Despite botulinum toxin (BTx) being the mainstay of treatment for Meige syndrome, a small subset of patients remain refractory to its effects because the disease is a form of functional blindness. An integrative surgical procedure combining selective myectomy and myotomy in situ of eyelid protractors, blepharoptosis correction, and tightening of the lower eyelid laxity was first applied to treat refractory blepharospasm in patients with Meige syndrome. MATERIALS AND METHODS: This study is a retrospective review conducted on 24 patients with refractory Meige syndrome between 2013 and 2020. Besides selective myectomy and myotomy in situ of eyelid protractors, levator plication and lateral tarsoplasty or canthopexy was performed for blepharoptosis correction and lower eyelid tightening, respectively. Patient demographics, associated diseases, medical treatment history, associated surgical procedures, final aesthetic outcomes, and therapeutic effects as reflected by changes in function disability score and Botox (BTx) treatment were thoroughly recorded and analyzed. RESULTS: The mean age of the patients was 65.2 ± 8.9 years. Twenty-one patients (87.5%) received blepharoptosis correction by levator plication with an average of 11.2 ± 2.9 mm in length. Lateral tarsoplasty was performed in 16 patients (66.7%) by pentagonal tarsal resection with an average of 3.9 ± 0.8 mm in width. Five patients (20.8%) received lateral canthopexy. Among the total of 96 operated eyelids, scar revision with fat graft was performed in 3 eyelids (3.1%). The average amount of BTx treatment decreased from 49.2 ± 12.8 U once every 2.7 ± 0.8 months before surgery to 35.4 ± 7.8 U once every 3.8 ± 0.7 months after surgery. Function disability score improved from 76.7 ± 17.5% preoperatively to 15.6 ± 9.9% postoperatively ( P < 0.001). Only 3 upper eyelids (3.1%) received scar revision and fat grafting due to minor postoperative contour depression. All patients expressed high satisfaction with both functional and aesthetic outcomes (Likert scale 4.5 ± 0.5). CONCLUSIONS: Selective myectomy and myotomy in situ of eyelid protractors combining blepharoplasty correction and lower eyelid tightening can produce long-lasting functional and aesthetic results with minimal complication in patients with refractory Meige syndrome.

[Efficacy of CT-guided partial radiofrequency ablation of bilateral responsible cranial nerves in the treatment of Meige syndrome].

Objective: To evaluate the efficacy of CT-guided partial radiofrequency ablation of bilateral responsible cranial nerves in the treatment of Meige syndrome. Methods: The Clinical data of 56 patients with Meige syndrome in the Department of Pain Medicine, Affiliated Hospital of Jiaxing University from June 2019 to January 2023 were retrospectively analyzed [19 males and 37 females, aged 42-76 (58.6±8.3) years], including 51 cases of blepharospasm, 3 cases of oromandibular dystonia and 2 cases of blepharospasm concomitant with oromandibular dystonia. CT-guided partial radiofrequency ablation of bilateral responsible cranial nerves was performed on different types of Meige syndrome. And the efficacy and complications of the technique were observed. Results: Fifty-one patients with blepharospasm Meige syndrome underwent CT-guided radiofrequency of facial nerve through bilateral stylomastoid foramen punctures, the symptoms of blepharospasm disappeared completely, leaving bilateral mild and moderate facial paralysis symptoms. Three patients with oral-mandibular dystonia underwent CT-guided radiofrequency therapy by bilateral foramen ovale puncture of mandibular branches of trigeminal nerve, masticatory muscle spasm disappeared, the patients had no difficulty opening the mouth, and the skin numbness in bilateral mandibular nerve innervation area was left. Two cases of Meige syndrome with blepharospasm concomitant with oromandibular dystonia were treated by radiofrequency of facial nerve and mandibular branch of trigeminal nerve, and all symptoms disappeared. The patients were followed up for 1-44 months after the operation, and the symptoms of mild and moderate facial paralysis disappeared at (3.2±0.8) months after the operation, but the numbness did not disappear. Three patients with blepharospasm recurred at the 14, 18 and 22 months after the operation, respectively, while the rest cases did not recur. Conclusions: According to different types of Meige syndrome, CT-guided partial radiofrequency ablation of responsible cranial nerves can effectively treat the corresponding type of Meige syndrome. The complications are only mild and moderate facial paralysis which can be recovered, and/or skin numbness in the mandibular region.

An Aesthetic Orbicularis Oculi Myectomy Technique for Blepharospasm: Use of Topical 5-Fluorouracil and Fibrin Sealant.

PURPOSE: To describe a modified technique of orbicularis oculi myectomy for refractory blepharospasm. This technique includes removal of orbicularis muscle, reformation of the eyelid crease and pretarsal platform using fibrin sealant (Tisseel), and topical 5-fluorouracil to reduce scar formation and improve aesthetic outcome. METHODS: Retrospective chart review of 7 patients who underwent bilateral orbicularis oculi myectomy with our technique from 2013 to 2016. Outcome measures were postoperative botulinum toxin dose, frequency, duration between treatments, the amount of lagophthalmos, severity of dry eye, and patient satisfaction with aesthetic and functional outcome. RESULTS: Patients who underwent the aesthetic myectomy technique had significantly decreased botulinum toxin use with relief of symptoms postoperatively. Only 1 of 7 patients experienced mild dry eye symptoms postoperatively, managed with artificial tears. All patients were satisfied with the aesthetic and functional outcome. CONCLUSIONS: The aesthetic myectomy technique provides effective treatment for blepharospasm with good functional and aesthetic outcome.

[Tarsal Kink: Pathognomonic Presentation and Therapy of a Rare Congenital Upper Eyelid Malformation]. / Tarsusknickung ("Tarsal Kink"): Pathognomonische Präsentation und Therapie einer seltenen kongenitalen Oberlidfehlbildung.

BACKGROUND: Presentation of a congenital abnormality that is rare, but follows a distinct course and can be diagnosed and cured promptly if the pathognomonic presentation is recognized. A congenital tarsal kink leads to a malposition of the upper eyelid margin that must not be missed, as it will lead to ulcerative keratitis if it is not treated. CASE PRESENTATION: An otherwise healthy newborn was presented after delivery with forceps with marked unilateral purulent secretion and blepharospasm. DIFFERENTIAL DIAGNOSIS: Neonatal dacryocystitis, gonococcal infection, congenital entropion with ulcerative keratitis, tarsal kink. EXAMINATION: It was not possible to fully examine the lid and cornea with the baby awake. Due to total inversion of the lid margin, no lashes could be seen. Under general anesthesia, the tarsal kink, with complete inversion of the lid margin and a corneal ulcer, was confirmed. TREATMENT: The literature offers several methods to correct this rare malposition, all of which aim to strengthen the anterior lamella to correct the kink. After incision of the kink and repositioning of the tarsus and securing the position with fixation sutures, the ulcer healed quickly and completely; lid closure and lid contour were normal and symmetrical. SUMMARY: Complete inversion of the lid margin is the pathognomonic sign of tarsal kink, giving the impression of "missing" lashes, accompanied by blepharospasm, followed by purulent secretion and corneal ulceration. The condition must not be misdiagnosed as only immediate correction can prevent severe damage.

Frontalis suspension surgery to treat patients with blepharospasm and eyelid opening apraxia: long-term results.

Blepharospasm may be accompanied by eyelid opening apraxia (EOA) reducing the efficacy of botulinum toxin (BT) therapy. The frontalis suspension operation (FSO) is then the only effective treatment option available. We want to report the first long-term results with FSO. We studied 15 patients with blepharospasm and EAO unresponsive to BT therapy (9 females, 6 males, age 61.9 ± 11.5 years). FSO was performed by applying 2 polytetrafluoroethylene threads (PTFE, Gore-Tex®) per eye connecting the frontalis muscle to the upper eye lid. Tension of the two carrés was set to produce a palpebral fissure width of 2-3 mm. Therapy outcome was monitored by a quality-of-life questionnaire (QoL-Q) and a self-assessment calendar reviewing postoperative days 0-9 (T1), 10-89 (T2), 90-179 (T3), 180-365 (T4), and >365 days (T5). Altogether, 40 FSO were performed. Postoperatively, all patients reported improved eyelid opening, 4 (27%) complete remission of symptoms. At T1, this improvement was 74.6 ± 26.4% on the self-assessment scale, after 1 year 68.2 ± 27.5%. Throughout the observation period (T1-T5), the improvement was 71.9 ± 25.6%. All 19 items on the QoL-Q (except for presence of involuntary eye lid closure) showed postoperative improvement. Adverse effects included circumscript upper eyelid haematomas, suture extrusion, suture granuloma, lacrimation, and infections. In all patients, BT therapy had to be continued to treat orbicularis oculi contractions. Our first long-term results demonstrate that FSO is a benign procedure producing robust and stable therapeutic effects on EOA in blepharospasm.

Persistent hemifacial spasm after microvascular decompression: a risk assessment model.

OBJECTIVE: Microvascular decompression (MVD) for hemifacial spasm (HFS) provides resolution of disabling symptoms such as eyelid twitching and muscle contractions of the entire hemiface. The primary aim of this study was to evaluate the predictive value of patient demographics and spasm characteristics on long-term outcomes, with or without intraoperative lateral spread response (LSR) as an additional variable in a risk assessment model. METHODS: A retrospective study was undertaken to evaluate the associations of pre-operative patient characteristics, as well as intraoperative LSR and need for a staged procedure on the presence of persistent or recurrent HFS at the time of hospital discharge and at follow-up. A risk assessment model was constructed with the inclusion of six clinically or statistically significant variables from the univariate analyses. A receiving operator characteristic curve was generated, and area under the curve was calculated to determine the strength of the predictive model. RESULTS: A risk assessment model was first created consisting of significant pre-operative variables (Model 1) (age >50, female gender, history of botulinum toxin use, platysma muscle involvement). This model demonstrated borderline predictive value for persistent spasm at discharge (AUC .60; p=.045) and fair predictive value at follow-up (AUC .75; p=.001). Intraoperative variables (e.g. LSR persistence) demonstrated little additive value (Model 2) (AUC .67). Patients with a higher risk score (three or greater) demonstrated greater odds of persistent HFS at the time of discharge (OR 1.5 [95%CI 1.16-1.97]; p=.035), as well as greater odds of persistent or recurrent spasm at the time of follow-up (OR 3.0 [95%CI 1.52-5.95]; p=.002) Conclusions: A risk assessment model consisting of pre-operative clinical characteristics is useful in prognosticating HFS persistence at follow-up.

Aesthetic and Non-aesthetic Indications for Orbicularis Oculi Myectomy.

INTRODUCTION: Crows' feet wrinkles are caused by the action of the orbicularis oculi muscle on overlying skin. Treatment options range from botulinum toxin to a multitude of surgical methods. We first described our technique in 2003 and refined it in 2006. We highlight the evolution of our technique and look at our results to assess the effectiveness of our technique. OBJECTIVE: The aim of this article is to show our experience of 13 years in 134 patients with our technique of orbicularis oculi myectomy. METHODS: From September 2000 to July 2013, we operated on 134 patients with an age range of 28-77 years. Of these patients, 104 had myectomies via lifting and 22 via a blepharoplasty approach. Five patients had myectomies for treatment of blepharospasm and a further three patients to restore symmetry in facial palsy. An evaluation of the results was performed by two medical students. RESULTS: Our results showed reduction of the wrinkles in all cases. For the statistical analysis the Wilcoxon test was performed. The p value was less than 0.001 showing a significant reduction of crows' feet wrinkles in both sides when the orbicularis myectomy was performed, via blepharoplasty or lifting. For myectomy performed for blepharospasm or facial palsy, the statistical analysis was not done due to the low numbers. CONCLUSION: In the appropriate patient, orbicularis oculi myectomy is an effective and long-term treatment for crows' feet wrinkles with a low risk of complications and high patient satisfaction.

Effect of upper eyelid myectomy on subsequent chemodenervation in the management of benign essential blepharospasm.

PURPOSE: Some patients with severe benign essential blepharospasm (BEB) become clinically refractory to chemodenervation with botulinum toxin. In these patients, surgical myectomy is an effective additive treatment for the management of this disabling condition. The purpose of this study is to determine how myectomy for BEB alters subsequent botulinum toxin administration. METHODS: A retrospective chart review of 27 patients undergoing surgical myectomy for the treatment of refractory BEB was conducted. The frequency and dosage of botulinum toxin were compared between preoperative and postoperative treatments. Paired Student t tests were used to determine significance (α = 0.05). RESULTS: The mean interval between botulinum treatments was 10.1 weeks preoperatively and 15.7 weeks postoperatively (p < 0.001). The mean quantity of botulinum toxin administered was 68 units prior to myectomy and 64.9 units postoperatively (p = 0.227). When comparing the quantity of botulinum toxin injected into the upper eyelid region only (site of myectomy), there was a significant decrease in the dose administered preoperatively and postoperatively (46.8 units vs. 39.9 units, p = 0.00310). CONCLUSIONS: Upper eyelid myectomy is an effective treatment modality for BEB in those patients who are refractory to botulinum toxin injections. Myectomy for BEB decreases the morbidity, botulinum toxin treatment frequency, and long-term expense associated with this disabling condition.

The long-term response to botulinum toxin injections in patients with blepharospasm undergoing upper eyelid surgery.

BACKGROUND: Upper eyelid surgery (UES) is a therapeutical strategy used for those patients affected by blepharospasm (BSP) who either do not respond or experience a gradual decrease in responsiveness to botulinum toxin (BoNT) injections. Nevertheless, most of them need to restart with BoNT despite the intervention. AIM: To evaluate the long-term post-surgical response to BoNT in patients with BSP and to identify predictive factors associated to treatment outcome. METHODS: We collected data of 60 BS patients, divided into two groups - blepharoplasty YES (8) and NO (52), collecting demographic - age, sex - and clinical data -disease duration, duration of the treatment with BoNT. Respective responses to injections - evaluated through the differences of both Jancovic Rating Scale and the Blepharospasm Disability Index pre and post BoNT (delta JRS and delta BSDI) just before their periodic three-month injection and after 1 month from it - were compared. Finally, clinical and demographics variables were included in multivariate regression and correlation analyses to assess their impact on the long-term response to injections. RESULTS: Patients who underwent UES had significantly lower delta at both scales, showing a poorer outcome after BoNT treatment. No variable was found to be associated with the response. DISCUSSION: Our data seem to suggest that surgery does not improve response to BoNT injections on the long run. As such, UES could be considered as an efficacious treatment in BSP just if evaluated soon after its performing. Long-term BSP management seems still difficult to be performed adequately and new therapeutical approaches are still needed.

Myectomy for blepharospasm 2013.

PURPOSE OF REVIEW: Botulinum toxin (BTX) injections are the main medical treatment of facial dystonias, but injections are ineffective in some patients. This review discusses the indications for myectomy and surgical technique for treating benign essential blepharospasm (BEB) and apraxia of eyelid opening (ALO). RECENT FINDINGS: There are four reasons to consider myectomy for patients with BEB. The first is ALO associated with BEB. The second is patients with blepharospasm-associated deformities. The third is patients who are truly unresponsive to BTX. The fourth is patients who cannot afford or who refuse BTX injections. SUMMARY: Myectomy remains essential for treating blepharospasm patients and the most common indication is those with associated ALO.

Concepts in eyelid biomechanics with clinical implications.

The inner canthal orbicularis drives spontaneous blinking of the eyelids and is richly innervated by a branching network of twigs based largely on the buccal branch of the facial nerve. This segment of the orbicularis is relatively resistant to denervation from subciliary incisional approaches. Combined with proper eyelid tension, contraction of this segment of orbicularis results in the normal physiologic blink mechanism. The authors discuss how to achieve proper eyelid tension and position intraoperatively during the treatment of patients with a range of orbital morphologies.

Skin contracture following upper eyelid orbiculectomy: is primary skin excision advisable?

AIM: To report the incidence and consequences of skin contracture following upper eyelid orbiculectomy. METHODS: A retrospective case note review identified 8 consecutive patients undergoing skin sparing upper eyelid limited orbiculectomy for essential blepharospasm associated with apraxia of eyelid opening. Clinical data collected from this review included age, gender, type of surgery performed, surgical complications, the need for additional surgeries, botulinum toxin treatment after surgery, dry eyes and blepharospasm functional disability assessment score. Pre and post operative photographs (at 1 year follow up) were used to assess the change in upper eyelid skin. RESULTS: The mean preoperative functional disability score was 72 ± 18 and improved to 25 ± 18 postoperatively at last follow-up. One patient needed botulinum toxin injections postoperatively. Intraoperative complications included bleeding in one case and haematoma in another case. Although we did not excise excess skin in any of our cases, we noted a reduction in upper eyelid skin excess in all cases, postoperatively. Restrictive lagophthalmos was noted in 3 cases (who had orbiculectomy alone) which required skin grafting and/or levator recession. CONCLUSION: Upper eyelid limited orbiculectomy with meticulous attention to pre-tarsal and pre-septal orbicularis only is effective in improving apraxia of eyelid opening and blepharospasm. Although we did not excise excess skin in any of our cases, we noted skin contracture postoperatively in three cases severe enough to require skin grafting or scar release. In our experience, skin contracture and orbital septal scarring appears to be relatively common following upper eyelid orbiculectomy, particularly if pre-tarsal and septal orbicularis is meticulously excised. In such a scenario we suggest avoiding concurrent excision of any dermatochalasis.

Extended frontalis orbicularis oculi muscle flap shortening for treating refractory apraxia of eyelid opening associated with blepharospasm.

BACKGROUND: Refractory apraxia of eyelid opening (AEO) is mostly unresponsive to botulinum toxin (BTx) and inevitably leads to functional blindness. To treat this challenging condition, an innovative surgical technique was proposed. METHODS: The extended frontalis orbicularis oculi muscle (FOOM) flap shortening consisting of frontalis suspension, partial myectomy, and myotomy in situ of eyelid protractors was applied to treat refractory AEO associated with blepharospasm. The postoperative outcomes and patient satisfaction were evaluated. RESULTS: Seven patients (mean ages 64.1 ± 3.9 years) of 14 eyelids in total had an average flap shortening distance of 24.4 ± 1.3 mm. During a mean follow-up of 31.6 ± 11.4 months, the average BTx dosage reduced from 58.6 ± 12. 1 units to 30.0 ± 8.2 units, with a mean injection interval decreasing from 2.3 ± 0.5 months to 4.1 ± 0.9 months (p < 0.05). Palpebral fissure height increased from 1.4 ± 0.5 mm to 7.9 ± 0.7 mm, and the disability scale decreased from 78.8% ± 7.2% to 12.6% ± 7.0% (p < 0.05). The postoperative BTx dosage and frequency were significantly reduced. All patients restored voluntary eyelid opening and reported high postoperative satisfaction (average Likert scale 4.6 ± 0.5). CONCLUSION: Extended FOOM flap shortening is an effective treatment to solve refractory AEO associated with blepharospasm.

Successful treatment of distichiasis in a cat using transconjunctival electrocautery.

A 2-year-old male castrated Domestic Short-haired cat presented to the Ophthalmology Service at the Matthew J. Ryan Veterinary Hospital at the University of Pennsylvania for evaluation of chronic bilateral ocular discharge and blepharospasm. Initial ophthalmic examination revealed severe conjunctivitis and keratitis and the presence of upper eyelid distichiae bilaterally. Initial therapy for suspected feline herpesviral infection provided moderate, but not complete, resolution of the clinical signs. Over the subsequent year, the cat suffered from recurrent, severe, ulcerative keratitis in both eyes despite appropriate medical therapy. Approximately 13 months after the initial presentation, the distichiae were surgically removed using transconjunctival electrocautery, which resulted in complete resolution of the clinical signs. This report documents bilateral distichiasis in a cat, a condition that is considered rare in this species.

Disabling muscle of Riolan: A novel concept of orbicularis oculi myectomy for refractory benign essential blepharospasm.

PURPOSE: To examine the effectiveness of orbicularis oculi myectomy with disabling the muscle of Riolan in patients with benign essential blepharospasm refractory to botulinum toxin-A (BTX-A) injection. METHODS: This retrospective, observational study included 25 patients. After removal of the redundant skin and underlying orbicularis oculi muscle (OOM) with or without extended OOM removal to the area of the superior orbital rim, the tarsal plate and the gray line were vertically severed at 2 points to disable the muscle of Riolan. The surgical effectiveness was evaluated using the visual analogue scale (VAS), functional disability score (FDS), and the presence or absence of necessity or enhanced effectiveness of BTX-A injection after surgery. RESULTS: The symptoms improved in 23 patients (92.0%). The VAS and total FDS were significantly improved from 8.4 ± 1.7 to 4.0 ± 2.4 (reduction rate, 50.7 ± 35.6%) and from 74.6 ± 22.2 to 34.7 ± 25.3 (reduction rate, 53.4 ± 27.4%) after surgery, respectively (both, p < 0.001). Among the 23 patients whose symptoms improved after surgery, BTX-A injection was not required in 11 of them (47.8%). Among the remaining 12 patients (52.2%), the effectiveness of BTX-A was post-operatively enhanced in eight patients (34.8%). There were no serious complications, and none of the patients experienced madarosis. CONCLUSION: Disabling the muscle of Riolan is a valuable option of OOM myectomy in patients with refractory benign essential blepharospasm, without the development of serious complications, including madarosis.

Orbicularis oculi myo-osseous fixation: a new treatment for benign essential blepharospasm and blepharospasm associated with diffuse facial dystonia (meige syndrome).

BACKGROUND AND OBJECTIVE: This article describes a novel surgical procedure, myo-osseous fixation, as an adjunct therapy for patients with reduced or poor response to repeated botulinum toxin injections for essential blepharospasm and Meige syndrome. PATIENTS AND METHODS: The small-incision, rapidly healing, rapidly performed technique uses self-drilling titanium screws tightly engaged with a compression wrench. The screws fixate the periorbital orbicularis oculi muscle to bone, creating mechanical resistance to outer portions of the orbicularis muscle involved in debilitating involuntary contractions. RESULTS: Eleven of the treated 12 patients experienced immediate improvement in function. Each responding patient noted enhanced effect of subsequent botulinum toxin injections at previously ineffective doses. The benefit was substantial and sustained for 6 months in 9 of 12 patients. Decreased brow depression during forced closure, forced frown, and brow elevation at rest was apparent in all patients postoperatively. Although the brow elevation effect was reduced after 6 months, reduced brow depression during forced closure still was easily demonstrated in most patients. Complications included a nodular bump over the brow, more commonly found when large titanium screws were used, transient headache, and easily removed dislodged screw. CONCLUSION: Initial data suggest that this procedure appears safe, well tolerated, and useful in the treatment of patients with essential blepharospasm and Meige syndrome responding poorly to botulinum toxin therapy.

Browlifting as an alternative procedure for apraxia of eyelid opening.

Essential blepharospasm is an idiopathic disorder that consists of spontaneous, spasmodic, and involuntary eyelid closure in the absence of ocular disease. Some patients develop an inability to open their eyelids in the absence of orbicularis spasms. These patients have essential blepharospasm combined with apraxia of eyelid opening. Botulinum toxin injections are the treatment of choice for blepharospasm but results may be insufficient, especially in cases associated with apraxia. Apraxia can be treated surgically by levator aponeurosis advancement, frontalis suspension, and upper myectomy. The authors report the first browlift using polypropylene suture to manage eyelid apraxia associated with blepharospasm as an alternative and minimally invasive procedure.

Upper eyelid myectomy in blepharospasm with associated apraxia of lid opening.

PURPOSE: To assess the impact of upper eyelid myectomy surgery on blepharospasm with associated apraxia of lid opening (ALO), dry eye, photophobia, and daily functioning in patients who are refractory to botulinum toxin treatment. DESIGN: Noncomparative, consecutive, interventional case series. METHODS: A retrospective chart review was performed to identify 100 consecutive patients beginning on January 1, 2000, who underwent upper eyelid myectomy surgery for blepharospasm and fulfilled the inclusion criteria. A survey was sent to all patients. Data were entered in an anonymous manner into a spreadsheet and analysis was performed using the Student t test with significance set at P<.05. RESULTS: Forty-five (88%) patients experienced ALO before surgery, among which 15 (33%) patients stated they were completely cured and 20 (44%) others had more than 50% improvement in ALO with surgery. In 20 of 30 patients who continued botulinum toxin treatment after surgery, the effect lasted longer. Twelve (29%) of 42 patients who experienced dry eyes before surgery improved. Eighteen (41%) of the 44 patients who experienced light sensitivity before surgery improved. Thirty-seven (82%) patients noted their cosmetic appearance to be better after surgery. The cumulative preoperative disability score was 14.11+/-5.78 (59%), whereas the cumulative postoperative disability score was 5.20+/-8.25 (22%; P<.01). CONCLUSIONS: Upper eyelid myectomy surgery appears to be effective in treating blepharospasm with associated ALO in most patients who are refractory to botulinum toxin injections and can provide improvement in the quality of life.
