Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
The TFOS DEWS II Pathophysiology Subcommittee reviewed the mechanisms involved in the initiation and perpetuation of dry eye disease. Its central mechanism is evaporative water loss leading to hyperosmolar tissue damage. Research in human disease and in animal models has shown that this, either directly or by inducing inflammation, causes a loss of both epithelial and goblet cells. The consequent decrease in surface wettability leads to early tear film breakup and amplifies hyperosmolarity via a Vicious Circle. Pain in dry eye is caused by tear hyperosmolarity, loss of lubrication, inflammatory mediators and neurosensory factors, while visual symptoms arise from tear and ocular surface irregularity. Increased friction targets damage to the lids and ocular surface, resulting in characteristic punctate epithelial keratitis, superior limbic keratoconjunctivitis, filamentary keratitis, lid parallel conjunctival folds, and lid wiper epitheliopathy. Hybrid dry eye disease, with features of both aqueous deficiency and increased evaporation, is common and efforts should be made to determine the relative contribution of each form to the total picture. To this end, practical methods are needed to measure tear evaporation in the clinic, and similarly, methods are needed to measure osmolarity at the tissue level across the ocular surface, to better determine the severity of dry eye. Areas for future research include the role of genetic mechanisms in non-Sjögren syndrome dry eye, the targeting of the terminal duct in meibomian gland disease and the influence of gaze dynamics and the closed eye state on tear stability and ocular surface inflammation.

Abstract
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.

Abstract
Damaged supraorbital neurovascular bundle during anterior orbital approach, fronto-glabellar reconstruction flap, supraorbital injection, blepharospasm, and Graves disease surgery is an important complication reported with varying frequency. The origin, calibration, and branches of the supraorbital artery and its topographical relations were investigated by injection of the arterial bed with red-dyed latex in 38 forehead regions. The supraorbital artery with the supratrochlear artery arose from the orbit as two separate vessels in 33 out of 38 forehead sides (87%). The supraorbital artery entered the frontalis muscle between 20 and 30 mm in 20 cases (52.6%), and between 30 and 40 mm in 16 cases (42.1%). This artery was located approximately the subcutaneous tissues between 40 and 50 mm in 17 cases (44.7%), between 50 and 60 mm in 18 cases (47.4%). The transverse supraorbital vein coursed at the level of the orbital rim on 22 sides (58%) and between 6.1 and 11.2 mm (mean: 9.4 mm) above the supraorbital rim on 16 sides (42%). All branches of supraorbital nerve were located between 2.0 and 3.2 cm from the midline at the level of the orbital rim. In 23 cases (60%), the lateral branch of the supraorbital nerve exited the bone as two branches, usually one large and one much smaller, which can together run into the scalp without further branching. In the present anatomical study, special attention was paid to morphological details concerning the neurovascular relationship of the supraorbital region. A better understanding of the midline forehead neurovascularity should allow modification of reconstructive techniques, afford better localization of the supraorbital nerve during blepharoplasty and ptosis surgery, and reduce the incidence of postoperative hematomas and nerve injuries.

Abstract
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.

Abstract
PURPOSE To examine the efficacy of differential section of the seventh nerve in treatment of patients with blepharospasm refractory to botulinum toxin and eyelid protractor myectomy. METHODS A retrospective noncomparative interventional case series consisting of a cohort of 228 patients with benign essential blepharospasm followed from 1987 to 1997 in a university ophthalmic plastic surgery referral practice. Patients were treated with botulinum toxin injections, eyelid protractor myectomy, and differential section of the seventh nerve in stepwise fashion as needed for symptomatic control. RESULTS Thirty-four patients (15% of total) underwent eyelid protractor myectomy during this period. Eyelid protractor myectomy failed to control blepharospasm in 7 (21%) of these 34 patients, who then underwent differential section of the seventh nerve an average of 2 years after myectomy. Patients were followed up for an average of 36 months, with a success rate of 42% (3 of 7). The remaining 4 patients had repeat differential section of the seventh nerve with a 50% success rate, which brought the overall success rate from differential section of the seventh nerve to 71%. Lower eyelid ectropion requiring surgical repair complicated 27% of differential section of the seventh nerve procedures. CONCLUSIONS Differential section of the seventh nerve is a reasonable alternative in the treatment of patients who have persistent disability despite treatment with botulinum toxin injections and eyelid protractor myectomy.

Abstract
The main objective in the treatment of blepharospasm is to decrease or cease the unwanted, repeated forced closure of the eyelids. This is best achieved by the use of botulinum toxin. In a minority of patients, botulinum toxin is either ineffective or poorly tolerated. In this group of patients, a trial with oral medication in the following order is warranted: trihexyphenidyl, baclofen, clonazepam, and tetrabenazine. Before going to the next medication, each of these drugs should be administered at the highest tolerated dosage for a period of 1 or 2 months. If, as often happens, all pharmacologic treatment attempts fail, and the patient is too disabled to remain untreated, he or she can be referred to an experienced plastic surgeon for a myectomy of the eyelid protractors. For treatment of apraxia of eyelid opening, botulinum toxin should be administered as the first treatment. If this fails, and vision is significantly impaired, the patient may be referred to a plastic surgeon for a frontalis suspension of the eyelid. Treatments of hemifacial spasm are aimed at decreasing or ending the annoying twitches of one side of the face. In this disorder, interference with vision is not a problem unless the contralateral eye is amblyopic. Despite isolated reports of spasm relief by drugs such as carbamazepine, oral medication is unlikely to be helpful. Botulinum toxin is the preferred treatment in hemifacial spasm patients. In some patients, relief from spasms can only be obtained at the cost of an ipsilateral upper lip droop of varying severity. Patients who are dissatisfied with the results of treatment with botulinum toxin, and are not willing to tolerate their condition, can be referred to an experienced neurosurgeon for microvascular decompression of the facial nerve. Pending success of ongoing attempts to reduce adverse effects, we believe that doxorubicin chemomyectomy, a recent treatment that has been used for both facial spasm and blepharospasm, is best administered in a research setting.

Abstract
Essential blepharospasm can be approached by several types of treatment: clinical in which the most important is the botulinum toxin with advantages and limitations; and some options of surgical treatment. The surgical technique described by Gillum and Anderson offers an alternative to patients resistant to the clinical treatment or with secondary complications. Two cases are analysed. Myectomy of all accessible orbicularis oculi, procerus and corrugator superciliaris muscle associated with blepharoplastic surgery and frontal lifting was indicated due to poor answer to clinical treatment. The results were satisfactory and both patients returned to their normal activities.

Abstract
This investigation was designed to extend our present knowledge of the supraorbital n. (SO n.) distal to the supraorbital notch. It is based on 40 dissected hemi-faces and the position of the notch and the periosteal and frontalis cutaneous branches of the SO n. were studied. The notch was 33.05 mm from the midline on the right side and 30.70 mm on the left. The periosteal branch arises from the lateral frontalis cutaneous branch. Its ascends in an oblique direction laterally and ends in two terminal branches. The frontalis cutaneous branch, after a very short trunk, divides into two branches, medial and lateral. The medial or deep branch enters the corrugator supercilii m. between its fibers. Most frequently, it passes under the inferior fasciculus and superficial to the middle and superior ones. Leaving the corrugator m., it ascends medially into the frontalis m., supplying the median cutaneous frontalis region. The lateral or superficial branch crosses superficial to the corrugator supercilii m. to penetrate the frontalis m. in an ascending and lateral direction, supplying the lateral frontalis region. The two branches enter the frontalis m., displaying a zigzag pattern in order to adapt its length during expressive movements. They cross the frontalis region together with the SO a. and two veins supplying the nerve and the frontalis m. These anatomic data may explain some of the complications after surgery for ptosis and blepharospasm.
