The pathogenesis of Meige's syndrome (MS) is controversial and has yet to be determined up to today. We studied a case of MS associated with post head trauma. The patient was a 52-year-old female. At the age of 46, she began to suffer from oro-lingual dystonia after head trauma induced by a traffic accident and the brief administration of neuroleptics to the delusion deteriorated the dystonia. She showed a wry appearance after 1 year and 6 months of the trauma and began to exhibit blepharospasms, oro-mandibular dystonia and cervical dystonia after 2 years and 3 months. For these symptoms her daily life became difficult. These symptoms were resistant to various drug therapies, although trihexyphenidyl relieved the symptoms transiently. Laboratory examinations and cranial MRI findings were normal. By surface electromyogram of ocular orbicular muscles, bilateral continuous discharge was observed. This patient was diagnosed as MS by clinical symptoms and surface electromyogram findings. It was inferred that the head trauma was associated with the development of MS. We discussed the pathogenesis of MS in the present case and it was speculated that MS was presented by a minute lesion of the brain stem which was produced at the time of the head trauma.

The results obtained in a retrospective study on clinical and pharmacological aspects of 41 patients suffering craniocervical dystonia (24 with blepharospasm, 17 with torticollis) and 11 with spasm are here presented. Mean age of symptoms onset was 57.4, 43.8 and 55.8 years old respectively; this variable was comparatively higher in females than in males with torticollis. The prevalence of blepharospasm and hemifacial spasm was higher in females. A 38.7% of patients suffering blepharospasm also presented oromandibular dystonia (Meige's syndrome). Other abnormal movements less frequently associated were cephalic tremor, postural hand tremor and larynx dystonia. In three cases with blepharospasm there was family history of Parkinson's disease and in two cases with torticollis there was family history of essential tremor. The mean age of onset was lower in patients with clonic torticollis and the evolution time of symptoms was longer than in those who presented the tonic type. Clonic torticollis were less frequently associated to pain. Trihexyphenidyl (anticholinergic) was the most efficient drug in craniocervical dystonia, and clonazepam in facial hemispasm. In general, as earliest the age of onset was, as better the therapeutical response was.

We have studied the effect of botulinum toxin in patients with focal dystonia, not responding sufficiently to medical therapy. Injection of 5-100 units to the muscles, selected by EMG and clinical examination, invariably resulted in reduction of muscle tonus, although to a different degree depending on the dosage. The outcome after the first trial was best when dealing with small muscles in patients with blephalospasm or Meige's syndrome. In contrast, several attempts were required for the treatment of a large muscle as in torticollis, or multiple muscles as in writers' cramps. The effect lasted 1-3 months. With precise selection of the affected muscles and careful regulation of necessary dosages, this type of therapy may contribute to the treatment of focal dystonia.

A case of idiopathic blepharospasm-oromandibular dystonia (Meige's syndrome) is reported, presenting as chronic bilateral dislocation of the temporomandibular joints. The nature of the syndrome is discussed, together with the difficulties in diagnosis and management.

Three cases of Meige syndrome with severe bilateral facial spasm were reported. All patients suffered from abnormal facial movement characterized by blepharospasm and oromandibular dystonia, and had atrophic changes of bilateral basal ganglia which were recognized by brain CT scan. Bilateral facial nerve block at the foramen stylomastoideum was applied to those three patients. Excellent results were obtained by this block technique in all the patients. The technique is not so sophisticated and is recommended for the treatment of the patient with Meige's syndrome.

Blepharospasm is a relatively frequent cranial dystonia which may be seen either alone or related to orofacial-mandibular dystonia (Meige's syndrome). In its maximum degree it can cause functional blindness.Twelve patients with blepharospasm (4 essential and 8 Meige's syndrome) who had been previously treated unsuccessfully with drugs (trihexyphenidyl, biperiden, carbamazepine, lithium, baclofen, lisuride, imipramine, clonazepam and butyrophenones) were treated for 12 months with periocular injections of botulinum toxin (BOTOX). A "low" dose of 12,5 U per eye was employed. With this dose, eleven out of twelve patients experienced significant improvement which lasted from five to fifteen weeks. The only nonresponder obtained complete relief upon duplicating the dose. The only side effect was uni or bilateral ptosis in six patients which improved completely in seven to twenty one days. One patient developed a peripheral facial palsy with complete remission in nineteen days. No systemic side effects were noted. There was only one desertion from this study due to depression enhanced by prolonged (21 days) ptosis. All patients (including the deserter) agreed that treatment with BOTOX provided more relief than any other previous therapeutic method. Our results confirm those obtained by others but a more prolonged study is needed to better evaluate long term effects.

We discuss the etiology of 100 spasmodic dysphonia patients. Seventy-one patients had underlying essential tremor, 25 had Meige's syndrome, 12 were hypothyroid, and 27 had either a functional disturbance or focal dystonia. Six patients had intermittent breathy dysphonia. A large corpus of spasmodic dysphonia patients have organic neurolaryngeal disease.

The acute effect of intravenous injections of biperiden and clonazepam was investigated in 14 patients with various forms of dystonia (segmental dystonia, 2; generalized dystonia, 6; and Meige's syndrome, 6). Eleven patients had primary dystonia, and 3 patients had a secondary form of dystonia. Doses of 5 mg of biperiden reduced dystonia when evaluated by total scores, global scores, and subjective scores. Two patients had marked side effects in the form of dizziness. Doses of 1 mg of clonazepam significantly reduced total scores and subjective scores, but the reduction in global score was insignificant. No patient had marked side effects following injection with clonazepam. These results correspond with earlier investigations of the long-term effects of anticholinergics and benzodiazepines. It is concluded that in some cases, intravenous injections can be used as a test for evaluating both effects and side effects of antidystonic medication prior to the institution of oral treatment. Long-term intravenous treatment might be considered in individual cases.

Thirty-one subjects affected by different movement disorders underwent polygraphic and videotape monitoring during nocturnal sleep, to assess movement patterns during the night. It was possible to distinguish two categories of disorders according to their pattern of movements. In the largest group (Meige's syndrome, blepharospasm, amyotrophic choreoacanthocytosis, Tourette syndrome, tonic foot, hemiballism) abnormal movements were still present during sleep, but decreased in frequency and amplitude in all stages. The second group presented three syndromes (nocturnal paroxysmal dystonia, nocturnal myoclonus, restless legs syndrome), in which light non-rapid-eye-movement sleep induced a strong activation of abnormal movements, whereas rapid-eye-movement sleep suppressed them.

Two patients developed difficulties in eyelid opening following long-term neuroleptic treatment of more than 6-8 years. Tardive dyskinesia and dystonia apart from the face were not found in either case. The symptoms fluctuated in their severities on a daily basis and were easily aggravated by various stimuli, e.g., stress, walking, reading and watching television. Electromyographic studies of their faces clearly indicated that the symptoms resulted from spontaneous blepharospasm and were analogous to idiopathic Meige's syndrome. Therefore, the patients' difficulties in opening their eyes were considered to be the so-called drug-induced Meige's syndrome and/or facial tardive dystonia. It must be stressed that this syndrome is extremely distressing to patients and is a severe complication accompanying a long-term neuroleptic treatment.
