The effects of percutaneous retrogasserian glycerol rhizolysis were observed in a population of 58 cases of classical trigeminal neuralgia. The follow-up period ranged from 7 to 52 months postoperatively. It was noted that 84% of the patients had immediate relief of pain. The overall recurrence rate was 29%. Based on Kaplan-Meier survival curves, the(More)
Essential blepharospasm is an idiopathic, progressively debilitating disease leading to blindness. Years of forceful spasms result in brow ptosis, dermatochalasis, and, frequently, levator aponeurosis and lateral canthal tendon defects. Following standard neurectomy procedures, the facies droop, brow ptosis and dermatochalasis worsen, and ptosis and canthal(More)
We performed a randomized double-blind crossover therapeutic bioequivalency study of a generic (Epitol) versus a brand name (Tegretol) carbamazepine product under steady-state conditions in 40 epileptic patients. Each patient received 90-day supplies of Epitol or Tegretol and placebo, which replaced the usual dosage of the alternate product. Group A(More)
Twenty-eight patients with pseudotumor cerebri underwent 40 optic nerve sheath fenestrations for relief of visual loss or to preserve vision. Twenty women and eight men underwent 16 unilateral fenestrations and 12 bilateral operations. Papilledema disappeared or was strikingly reduced in 24 of 28 patients. The other four patients had gliotic discs (two(More)
Essential blepharospasm is an idiopathic disorder of progressive involuntary spasms of the orbicularis oculi and upper facial (corrugator, procerus) muscles. Blepharospasm literally means spasm of the eyelids; however, most patients with blepharospasm also have or will develop squeezing in the lower face and neck muscles (Meige's syndrome, orofacial(More)
The paralytic properties of botulinum A toxin have led to its use in humans in the treatment of strabismus and facial dystonias such as essential blepharospasm. Examination of orbicularis muscle from 10 patients with essential blepharospasm who received 2-18 injections of botulinum toxin 6 weeks to 3 years prior to surgery revealed characteristic nodal,(More)
