Frontalis suspension combined with blepharoplasty as an effective treatment for blepharospasm associated with apraxia of eyelid opening

Blepharospasm Secondary to Deep Brain Stimulation of the Subthalamic Nucleus in Parkinson Disease: Clinical Characteristics and Management Outcomes

BACKGROUND

Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an effective treatment for patients with motor symptoms of Parkinson disease but can be complicated by disabling blepharospasm and apraxia of eyelid opening (ALO). Currently, there is no clear consensus on optimal management, and addressing these issues is further hindered by systemic morbidity and resistance to treatments. We aim to describe the different phenotypes of these eyelid movement disorders, to report our management approach and patient responses to treatment.

METHODS

A retrospective case series of all patients with blepharospasm/ALO secondary to STN-DBS that were treated at a tertiary center between 2011 and 2020. Data collected included date of Parkinson diagnosis, date of DBS surgery, date of development of blepharospasm/ALO symptoms, STN-DBS stimulation settings, and treatment given. Patients' symptoms before and after treatment were measured using the blepharospasm disability index and Jankovic Rating Scale.

RESULTS

Five patients were identified with eyelid movement disorders secondary to STN-DBS. All patients had moderate-to-severe symptoms at presentation. Four patients received periocular botulinum toxin injections. Three patients underwent surgery in the form of frontalis suspension or direct brow lift with or without upper lid blepharoplasty. All reported an improvement in symptoms following treatment.

CONCLUSIONS

A multimodality, patient-specific approach is required in the treatment of blepharospasm/ALO secondary to STN-DBS. Botulinum toxin injections can be effective, but patients may require surgery if toxin treatment alone becomes ineffective. Tailoring treatment to individual needs can result in a measurable improvement in symptoms.

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.

SURGICAL ASPECT OF BLEPHAROSPASM TREATMENT: A CASE REPORT

Blepharospasm is an idiopathic condition characterized by involuntary eyelid closure mainly caused by bilateral tonic-clonic contractions of the orbicularis oculi muscle. It results in patient inability to open their eyes, thus significantly impairing their ability to perform activities of daily living. First-line treatment for blepharospasm are primarily botulinum toxin type A injections. However, surgical procedure as a treatment option can also be taken in consideration. In this overview, we present a case of a 75-year-old female patient who received surgical treatment as per Anderson's method after being treated with botulinum toxin type A for 3 years. This form of therapy proved to be an extremely successful permanent solution in the treatment of severe cases of refractory blepharospasm, without any long-term complications, especially ectropion and lagophthalmos.

Polytetrafluoroethylene frontalis suspension in blepharospasm with eyelid apraxia: an effective and well-tolerated adjunct to botulinum toxin therapy

Purpose: To report the efficacy of polytetrafluoroethylene (PTFE) frontalis suspension for blepharospasm with eyelid apraxia and postoperative botulinum toxin requirements. Methods: Retrospective chart review of patients with blepharospasm and eyelid apraxia who underwent frontalis suspension. The primary outcome was a surgical success, defined by surgeon- and patient-reported success in postoperative eyelid opening. Comparative statistical analyses of botulinum toxin dosage and treatment intervals were performed amongst patients before and after frontalis suspension ptosis repair. Results: Five patients (10 eyelids) met the study criteria, of which 40% were female. Mean age was 63.2 years. All patients had successful surgical outcomes based on physician-reported and patient reported satisfaction with the postoperative eyelid opening. Average follow-up was 14 months. Preoperative botulinum toxin treatments averaged 80.4 units (range 32-110, SD 33.2) to the periocular region over an average of 9.6-week intervals. Postoperative botulinum toxin treatments averaged 61.4 units (range 24-110, SD 34.7) to the periocular region over an overage of 9.8-week intervals. No patients experienced postoperative exposure keratopathy, extrusion of the sling, or postoperative infection. Conclusions: Frontalis suspension using PTFE suture in the setting of blepharospasm with eyelid apraxia was found to be a safe and effective procedure. Frontalis suspension in this population is not a substitute for botulinum toxin treatment but may allow for reduced treatment dosage. Frontalis suspension appears to increase patient functionality with improved eyelid opening in patients with blepharospasm with eyelid apraxia.

Surgical approach to limiting skin contracture following protractor myectomy for essential blepharospasm

Purpose

To report our experience with protractor myectomy in patients with benign essential blepharospasm who did not respond to serial botulinum toxin injection, and to describe intra- and postoperative techniques that limited skin contracture while also providing excellent functional and cosmetic results.

Methods

The medical records of patients with isolated, benign, essential blepharospasm who underwent protractor myectomy from 2005 to 2008 by a single surgeon were reviewed retrospectively. The technique entailed operating on a single eyelid during each procedure, using a complete en bloc resection of all orbicularis tissue, leaving all eyelid skin intact at the time of surgery, and placing the lid under stretch with Frost suture and applying a pressure dressing for 5-7 days.

Results

Data from 28 eyelids in 7 patients were included. Average follow-up was 21.5 months (range, 4-76 months). Of the 28 eyelids, 20 (71.4%) showed postoperative resolution of spasm, with no further need for botulinum toxin injections. In the 8 eyelids requiring further injections, the average time to injection after surgery was 194 days (range, 78-323 days), and the average number of injections was 12 (range, 2-23 injections). All but one eyelid had excellent cosmetic results, without signs of contracture; one eyelid developed postoperative skin contracture following premature removal of the Frost suture and pressure dressing because of concerns over increased intraocular pressure.

Conclusions

In our patient cohort, this modified technique resulted in excellent cosmetic and functional results and limited postoperative skin contracture.

Eyelid Dysfunction in Neurodegenerative, Neurogenetic, and Neurometabolic Disease

Eye movement abnormalities are among the earliest clinical manifestations of inherited and acquired neurodegenerative diseases and play an integral role in their diagnosis. Eyelid movement is neuroanatomically linked to eye movement, and thus eyelid dysfunction can also be a distinguishing feature of neurodegenerative disease and complements eye movement abnormalities in helping us to understand their pathophysiology. In this review, we summarize the various eyelid abnormalities that can occur in neurodegenerative, neurogenetic, and neurometabolic diseases. We discuss eyelid disorders, such as ptosis, eyelid retraction, abnormal spontaneous and reflexive blinking, blepharospasm, and eyelid apraxia in the context of the neuroanatomic pathways that are affected. We also review the literature regarding the prevalence of eyelid abnormalities in different neurologic diseases as well as treatment strategies (Table 1).

Upper lid orbicularis oculi muscle strip and sequential brow suspension with autologous fascia lata is beneficial for selected patients with essential blepharospasm

PURPOSE

Severe cases of blepharospasm resistant to botulinum toxin represent a challenging clinical problem. Over the last 10 years, we have adopted a staged surgical management of these cases with an initial upper lid orbicularis myectomy (combined with myectomy of procerus and corrugator supercilius as appropriate) and then 4-6 months later a brow suspension with autologous fascia lata. The aim of this study was to assess the outcome of this staged surgical approach.

MATERIALS AND METHODS

A questionnaire was sent to all patients who had undergone the procedure and the clinical records reviewed.

RESULTS

Fourteen patients had undergone the procedure of which 13 were alive. They were sent a questionnaire and 10 of them responded. All had both procedures. Eight of the 10 reported great benefit from the surgery, one some benefit, and one was worse off. All patients still required botulinum toxin injections after the surgery.

CONCLUSIONS

Majority, but not all, of the patients in our series greatly benefitted from this staged surgical approach.

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.

Long-term follow-up of patients with frontalis sling operation in the treatment of essential blepharospasm unresponsive to botulinum toxin therapy

OBJECTIVE

Botulinum toxin is the treatment of choice in patients with essential blepharospasm, but about 4% of patients show no sufficient effect. Many of these patients try to open their eyes by innervating their frontalis muscle. This led to the idea of performing frontalis suspension, normally used for certain types of ptosis. We set out to evaluate the long-term results, complication rates and patient acceptance of this intervention.

METHODS

Frontalis sling operation was carried out on 252 eyes of 132 blepharospasm patients between 1992 and 2004. In all patients botulinum toxin treatment was administered before surgery with no or only brief and incomplete effect even with increasing toxin doses. In 120 patients surgery was performed under local anaesthesia, while 12 patients were operated upon under general anaesthesia (mostly bilateral). Silk sutures were employed in the first 14 eyes, and in all others we used Gore-Tex suture material.

RESULTS

The duration of follow-up was 3-154 months; 60 patients were followed up for at least 5 years. Seventy-three per cent of patients reported an improvement after surgery. Long-term subjective improvement showed a median of 50% on a scale ranging from 0%=no improvement to 100%=no complaints. No serious corneal complications occurred, although slight overcorrection is desirable in the first days after surgery for a satisfactory long-term result. Seven per cent of operations had to be revised due to suture granulomas or extruded suture material. The effect of surgery generally remained stable over the years, with most patients needing additional treatment with botulinum toxin. In cases of decreasing effect (5% of eyes), the sutures were tightened under local anaesthesia.

CONCLUSION

Frontalis suspension can be considered as a minimally invasive but very effective and even reversible procedure in "poor responders" to botulinum toxin, with good long-term effect and good acceptance by the patients. Additional treatment with botulinum toxin is required in most patients in order to increase the desirable imbalance between the frontalis and the orbicularis muscle.

Apraxia of eyelid opening: clinical features and therapy

PURPOSE

Botulinum toxin injection is the treatment of choice in cases of benign essential blepharospasm. However, about 10% of the patients do not get sufficient effect from this treatment, and many of them have concomitant apraxia of lid opening.

METHODS

Over a 3-year period we treated 12 patients. Three had pure apraxia of lid opening and in the other nine it was associated with blepharospasm. All patients were initially treated with botulinum toxin injections with poor results. They underwent surgical treatment like blepharoplasty, limited myectomy, aponeurosis repair, and/or frontalis suspension. Some of them needed post operative botulinum toxin injections in the pretarsal part of orbicularis oculi muscles.

RESULTS

This combined therapy gave good functional and aesthetic results.

CONCLUSIONS

The specific causes of blepharospasm and apraxia of lid opening are unknown, but these two conditions coexist in some patients and can be difficult to treat. It is important to make a correct diagnosis, and a combined surgical and botulinum toxin treatment can be very effective.

Blepharospasm and hemifacial spasm: a protocol for titration of botulinum toxin dose to the individual patient and for the management of refractory cases

PURPOSE

To evaluate a protocol for the treatment of facial dystonias.

METHOD

A retrospective noncomparative interventional case series of all patients who attended a specialised tertiary referral clinic between January 2000 and January 2003. At the start of treatment, patients were seen and treated at weekly intervals until their symptoms were controlled or they developed complications. The sum of the weekly doses was taken as the individual patient dose and then given at 3-4 monthly intervals as required for the individual patient. Refractory cases of spasm underwent orbicularis muscle reduction. Pretarsal spasm was treated with pretarsal botulinum toxin. If the spasm was relieved but the patient could not open their eyelids, a trial of ptosis props was undertaken and the toxin injections continued, before considering a brow suspension. If patients could not see because of a spastic Bell's phenomenon, they were given centrally acting systemic medication.

RESULTS

Of 182 new patients, 63 (35%) required two or more sets of injections to titrate their optimum dose of toxin. Symptoms improved in 169 patients (93%). Of a total 332 new patients and follow-up patients, 47 (14%) underwent surgery during their management, 36 protractor myectomy, and 13 brow suspension. Protractor myectomy improved symptoms in 23 (64%). Brow suspension improved symptoms in 12 patients (92%).

CONCLUSIONS

The dose of botulinum toxin can be titrated to the individual patient, and the refractory cases managed satisfactorily if a logical protocol is followed.

Assessment of Blepharospasm Surgery Using an Improved Disability Scale: Study of 138 Patients

PURPOSE

To assess a new scale for grading functional disability in a series of patients operated on for blepharospasm resistant to treatment by botulinum toxin (BT) injections.

METHODS

The bicentric study included 138 patients: 80 (58%) with essential blepharospasm; 46 (33%) with apraxia of eyelid opening; and 12 (9%) with intermediate forms. They had undergone orbicularis myectomy (92 cases, 67%), frontalis suspension (31 cases, 22%), or both (15 cases, 11%). Functional disability was assessed by using an original scale covering 6 daily life activities, each graded using 5 levels from 0 (no disability) to 4 (activity impossible). The score obtained was related to the total of activities actually performed to produce a functional disability score (FDS) from 0 to 100. Each patient's FDS was prospectively determined, before surgery and 3 months after surgery (M3). In patients who, after surgery, required a further course of BT injections, the FDS was assessed immediately before the third injection.

RESULTS

The mean FDS fell significantly, from 78 +/- 15 (standard deviation) before surgery to 45 +/- 21 at M3 (p < 0.01%), whatever the clinical form of essential blepharospasm or surgical procedure. The mean postoperative FDS was significantly lower in the 62 patients (45%) weaned off BT than in the unweaned group, respectively (31 +/- 17 versus 56 +/- 18; p < 0.01). In the latter group, the mean FDS after BT reinjection (34 +/- 19) fell to a level comparable with that of the weaned patients.

CONCLUSIONS

This accurate, easy-to-use scale makes it possible to quantify in patients with blepharospasm functional improvement as the result of surgery and, where applicable, of BT reinjection.

Advancement of the frontalis muscle for ptosis of the brow associated with essential blepharospasm

We evaluated our results of advancement of the frontalis muscle to correct brow ptosis associated with blepharospasm in five patients who had difficulty opening their eyelids as a result of ptosis even after injections of botulinum toxin. The frontalis muscle was retracted inferiorly and connected directly to the skin of the eyebrow. Postoperatively the level of the eyebrow was raised above the superior orbital rim in all cases during the observation period (4 to 15 months). Although the operation did not improve muscle spasms, it successfully shortened the duration of involuntary closure of the eyelid. The only postoperative complication was lymphoedema of the eyelids. Results of postoperative injection of botulinum toxin were satisfactory. Advancement of the frontalis muscle corrects brow ptosis without major complications, and is complementary to injection of botulinum toxin.

Orbicularis oculi muscle graft augmentation after protractor myectomy in blepharospasm

PURPOSE

To evaluate the effectiveness of free orbicularis oculi muscle grafts in correcting volume deficit deformities after protractor myectomy in patients with essential blepharospasm.

METHODS

Prospective case series. During the 13-month period from October 2000 through November 2001, all patients with essential blepharospasm undergoing primary eyelid protractor myectomy received an orbicularis oculi muscle graft to replace the volume deficit deformity created by the myectomy. Only patients who had at least 6 months of postoperative follow-up were included in the analysis.

RESULTS

Forty-six patients underwent primary eyelid protractor myectomy and had a free orbicularis oculi muscle graft for volume replacement. All patients had significant functional improvement of their eyelid spasms after the myectomy. Of the 38 patients who underwent upper eyelid myectomy, 3 patients were overcorrected and no patients were undercorrected with the orbicularis muscle graft. Two of the overcorrected patients underwent surgical debulking of their muscle grafts. Of the 8 patients who underwent lower eyelid myectomy, no patients were overcorrected and 1 patient was undercorrected. None of the patients were observed to have any spasms, contractions, or other signs of muscular activity or aberrant innervation of the muscle graft.

CONCLUSIONS

The orbicularis oculi muscle graft is a useful adjunct to protractor myectomy in improving the aesthetic outcomes for blepharospasm patients. Our study demonstrates the viability of the orbicularis oculi muscle graft and may lead to future applications of the graft in facial aesthetics.
