Retraction of the lower eyelid is a useful sign of disease. It is an early manifestation of weakness of the facial muscles, occurring with myopathies, myasthenia, and upper and lower motor neuron facial paresis. Rarely, lower and upper lid retraction occur without proptosis in patients with Graves disease. Lower lid retraction occurs in proptosis and varies directly with the degree of proptosis. It is also seen with senile entropion or ectropion, after eye muscle or orbital surgery, and with contraction of lid tissues. Apparent retraction results when the contralateral lower lid is pathologically elevated, as in Horner syndrome, in enophthalmos, or with vertical deviations of the eye.

In a 12-year-old girl with Horner's syndrome and an ipsilateral accommodative paresis, intravenous administration of edrophonium chloride improved the accommodative defect on several occasions, which suggested a possible relationship to myasthenia gravis. Additional testing of the accommodative paresis revealed some of the characteristics of Adie's syndrome and suggested a relationship to pupil-sparing Adie's syndrome.

Peripheral nerve injuries may complicate extracranial vascular surgery. Pareses of the recurrent and hypoglossal nerves are clinically important. The nervus laryngeus superior, the ramus marginalis mandibulae of the facial nerve and the brachial plexus may be involved. Horner's syndrom indicating damage of sympathetic fibers may also appear. Lesions of the glossopharyngeal, vagus and phrenic nerves are rather seldom.

The authors report a woman aged 53 years with the main components of the syndrome of Opalski coexisting with signs characteristic of Wallenberg's syndrome. The lacking components of the former syndrome included Horner's syndrome, while nystagmus, diplopia without evident oculomotor nerves, paresis, disturbances of speech and deglutition belonged to the latter syndrome. The clinical pattern and the course of the disease suggested a vasogenic focus in the right submedullary region and inferolateral part of the medulla.

A rare case of extraskeletal ossification in the parapharyngeal region related to C2 cervical vertebra was observed in a child, without any history of trauma, inflammation or endocrinological disease. One-step surgical intervention was carried out from the side of the neck and pharynx making possible complete removal of the lesion. The girl was admitted to the hospital with dysphagia and breathing difficulties increasing in the last 6 months. During that time the child was observed in laryngological hospital departments. After the operation Horner syndrome and hypoglossal paresis developed, but presently the child is without symptoms.

The records of 90 cases of oculosympathetic paresis (1982-1991), 39 women and 51 men aged between 3 months and 82 years, were evaluated. The mean baseline anisocoria was 0.92 mm but did not exceed 2.4 mm. The mean difference in the position of the upper eyelid was 2.3 mm. Enophthalmus of 1 mm or more was found in only 25% and exophthalmus of 1 mm or more, in 18%. Exophthalmus or enophthalmus of more than 2 mm was not encountered. The cocaine test (5% solution in most cases) was performed in 85 cases and could be quantified in 65 cases. The average dilation of the involved pupil was 0.52 mm, whereas the normal pupil dilated 2.14 mm. The average postcocaine anisocoria was 2.54 mm. Hydroxyamphetamine 1% dilated the involved pupil in cases with presumed preganglionic lesions slightly more than the normal fellow pupil (2.39 mm and 2.09 mm respectively). The difference was significant (P < 0.05). In postganglionic lesions, the hydroxyamphetamine dilation was 0.57 mm. The hydroxyamphetamine test had a specificity of 90% for postganglionic lesions and 88% for preganglionic. An underlying acquired disease could be identified in 53 cases; 6 cases were congenital. In 37 cases (including the congenital ones), no cause was found. Among the 33 preganglionic lesions, only one malignant tumor was found, whereas 6 malignant tumors were encountered among the 20 postganglionic cases. Additional ocular motor palsies or other local signs were present in these 6 cases. Goiter was frequently associated with preganglionic Horner's syndrome.

Five patients with acquired monocular elevation paresis were investigated using direct current electroculography. With recovery, upward saccade velocities significantly increased in both eyes in all patients. The gain of upward-following eye movements significantly increased in the paretic eye of all patients and in the opposite eye of four patients. These findings are interpreted in terms of an asymmetric upgaze palsy which clinically presented as monocular elevation paresis in the more severely affected eye. A brainstem lesion contralateral to monocular elevation paresis was suggested in four patients by contralateral Horner's syndrome and contralateral abduction paresis, each in one patient, and contralateral ptosis in two patients. In only one patient, computerized tomography and magnetic resonance imaging substantiated a contralateral meso-diencephalic lesion.

To determine if recent trends in evaluation and therapy have contributed to the successful surgical management of carotid body paragangliomas, we reviewed our experience over the past decade. Nineteen carotid body paragangliomas were identified in 17 patients. Eleven patients underwent complete, preoperative embolization of their afferent arteries with one complication. Calculated carotid body paragangliomas surface areas did not differ between the embolized 64.6 +/- 43.3 cm2 and nonembolized 63.0 +/- 57.9 cm2 lesions. Intraoperative blood loss was lower (p = 0.02) in the patients treated with embolization (372 +/- 213 ml) compared with their cohorts (609 +/- 564 ml). However, the operative times were equivalent 4.1 hours versus 4.5 hours in both groups. Intraoperative electroencephalographic (EEG) monitoring was used in 10 patients; in one patient the EEG indicated intraoperative thrombosis of the carotid artery, which was successfully treated by thrombectomy without complications. Two patients required carotid bifurcation resection and vascular reconstruction to remove the entire tumor; a late stroke manifested by contralateral hand weakness developed in one of these patients. The incidence of cranial nerve injury was low at 16%, with one transient ramus mandibularis paresis and two instances of vocal cord dysfunction. Two additional patients had a postoperative Horner's syndrome. We conclude that by diminishing intraoperative blood loss through complete and careful preoperative embolization and use of intraoperative EEG monitoring along with careful surgical technique, the complications associated with this challenging operation are facilitated and diminished.

A 7-year-old boy developed a Horner's syndrome after falling on a stick that penetrated his peritonsillar soft palate. He did not suffer from any major vascular injury, and pharmacologic testing indicated a preganglionic lesion. We review previously reported cases of oculosympathetic paresis caused by surgical and nonsurgical intra-oral trauma. Because of the proximity between sympathetic and vascular structures in the lateral and parapharyngeal space, Horner's syndrome in the setting of intra-oral trauma should prompt evaluation of the internal carotid artery. Magnetic resonance imaging may be a reasonable noninvasive method for this investigation.

Since 1978, the authors have observed 7 cases of dissecting aneurysm in the internal carotid artery. Symptoms were severe headache and subsequent neurologic deficit in young persons (3 women, 4 men; mean age 35 years). The underlying pathology was spontaneous dissection of the cervical internal carotid artery, with surgical confirmation in 3 cases and typical angiographic patterns in all cases. Spontaneous dissection of the cervical internal carotid artery is being increasingly recognized as a cause of cerebral ischemia in young adults. Moreover this clinicopathologic event is more common than had previously been supposed. The etiology remains unclear, except in 15% of cases in which dystrophy of the media (Marfan's syndrome) is in cause. No history of cervical trauma can be found. Typical clinical features consist in ipsilateral headache preceding an abrupt neurologic deficit in a 40-year-old person. An incomplete Horner syndrome (oculosympathetic paresis without facial anhidrosis) associated with facial pain and numbness is pathognomonic, but the majority of dissections are less typical. The typical angiographic pattern is an elongated regular stenosis of the high cervical internal carotid artery, 2 cm above the non-involved bulbus ("string sign"). The dissection may modify to a tapered occlusion above the point of origin of the internal carotid artery. The natural course is spontaneous resolution of the stricture, without relapse. Optimal management is non-operative since medical treatment has proved to be efficient. These cases confirm the benign course and overall good prognosis of spontaneous dissections of the internal carotid artery which are not as rare as the scarcity of reports might indicate.(ABSTRACT TRUNCATED AT 250 WORDS)
