Augmentation of a vocal fold serves to improve glottic closure and may be indicated for paresis of the recurrent nerve and after tumor resection. Methods include injection of viscous fluids (paraffin, liquid silicone, polyvinyl alcohol, gelatin, sesame oil, collagen and particularly teflon paste) and operations to tighten the vocal cord or displace it medially. The disadvantages of the former include the danger of overcorrection, tissue irritation and possible systemic absorption of the material. As an alternative, solid material such as cartilage or synthetics may be used for augmentation. Experience obtained so far has shown that chips of porous polyethylene (PHDPE) are particularly suitable: they are easy to use, show good tissue tolerance and are anchored by ingrowth of connective tissue. The value of photokymography of the larynx in the assessment of therapeutic results after vocal-fold augmentation is discussed.

A case of epidermoid carcinoma arising in an epidermoid cyst in the cerebellopontine angle is presented. Clinical features and CT appearance are discussed in comparison with those of benign epidermoid cyst. A 43-year-old man was admitted to the Department of Neurosurgery, University of Tokyo Hospital on April 14, 1983, with complaints of right facial numbness and weakness of six months' history. On neurological examination, sensation of the right half of the face was decreased in all modalities. Marked atrophy of the ipsilateral temporal muscle was also noted. Right facial paresis of peripheral type was evident. Gag reflex was decreased on the same side. Except for a slightly increased left deep tendon reflexes, there were no pyramidal tract signs. A CT without contrast material failed to show any abnormalities. A postcontrast CT demonstrated an irregular enhancement in the right cerebellopontine angle. The finding of asymmetry of the ambient cistern indicated minimum mass effect on the metrizamide CT cisternography. Suboccipital exploration of the right cerebellopontine angle was carried out on April 28, 1983. Leaving a part of the capsule indenting the pons between the roots of the fifth and the seventh nerve, we removed a white pearly tumor. Histological diagnosis was typical epidermoid cyst. He left the hospital one month later with signs of the right seventh and the eighth nerve. His postoperative course, however, was beyond our expectation. Over a few months following his discharge, left hemiparesis as well as horizontal and vertical nystagmus gradually developed. He was readmitted on November 10, 1983. A postcontrast CT revealed enlargement of the enhanced lesion filling the right ambient cistern.(ABSTRACT TRUNCATED AT 250 WORDS)

A 63-year-old man developed bilateral paresis of horizontal and upward eye movements. He was found to have a small oat cell carcinoma of the lung. Four months later he experienced acute visual blurring on the right side. Examination of the right eye at that time revealed a visual acuity of 3/200 and a central scotoma. There was swelling of the right optic disc. Three weeks after the onset of the visual loss, the acuity of the right eye spontaneously improved to 20/60, the field deficit lessened, and there was a decrease in the swelling of the optic disc. Subsequently, his neuro-ophthalmologic condition remained unchanged but his general health deteriorated, and he died nine months after the onset of the disease. Neuropathologic examination showed mild perivascular lymphocytic infiltration and fibrosis of the meninges throughout the central nervous system, loss of neurons and gliosis in the third and fourth cranial nerve nuclei, perivascular inflammation and gliosis of the optic nerves, and chiasm and central demyelination of the right optic nerve. No tumor cells were seen. These findings were consistent with a diagnosis of paraneoplastic optic neuritis and paraneoplastic encephalomyelitis. The present case confirms the existence of paraneoplastic optic neuritis and illustrates the clinical course of the disease.

This article describes the general and specific interpretations of common laboratory tests used to evaluate bovine neurologic disease. Cerebrospinal fluid analysis is emphasized. Comments are made about general conclusions such as hemorrhage, inflammation, infection, and neoplasia as well as specific diseases like thromboembolic meningoencephalitis. Tests in commonly available serum chemistry profiles like total calcium concentration and aspartate aminotransferase activity are described in terms of their usefulness in diseases such as parturient paresis or hepatic encephalopathy. The indications for more specific tests like ionized calcium, blood ammonia concentration, or erythrocyte transketolase are included.

Between 1973 and 1980 a solution of phenol in glycerin into the cisterna magna was injected in 38 patients suffering from advanced intractable pain due to neoplasm of faciocephalic area. Owing to the poor neurological and general condition of our patients, surgical procedures were discarded. Patient's age ranged from 36 to 76 years and pain diffusion involved many cranial and cervical nerves. Follow-up studies after phenol injections were carried out in 22 patients: mean survival time proved to be 137 days. In 76% of cases, before neurolytic treatment, narcotics had been administered. In this series pain relief seemed to be poor in 50%, good in 34% while it was unclassifiable in the remaining 16% of the cases due to an incomplete follow-up. These last patients were likely to show favorable results. Complications arising immediately after phenol injections are described. Long lasting disabling neurological deficits were recorded in 18% of cases. Less severe complications were shown in 71% of the patients. The most frequent ones were impairment of sensory functions of the trigeminal area and reversible paresis of the 7th cranial nerve. Despite the poor general conditions, no fatal outcome was seen in our patients. No significant relationship between pain relief and sensory deficit was found. The pathophysiological mechanisms of pain suppression, induced by phenol injection in the faciocephalic area are discussed. The value of this simple technique is briefly assessed in comparison to other analgesic procedures.

From 1973 December to 1986 September, we have experienced 2,500 cases of radiation treatment, of which 237 cases have been with bone metastasis. X-ray CT was examined on the 19 cases to detect the bone metastasis. The detective rate was 89.5% with bone scintigram alone improved to 94.7% with both bone scintigram and X-ray CT. Serum Alkali phosphatase (Al-p) were measured after and before radiation treatment on 147 cases. Values of Al-p increased on 64.6% cases measured and when values of Al-p were decreased after radiation treatment, good treatment effects were showed. Electron microscope disclosed that Al-p has existed around cell membrane of metastatic tumor cell. We considered there is a correlation between increment of Al-p in blood and contents of Al-p in bone metastatic tissues. Judgement of effects of radiation treatments were scored by three grades of pain relieving on 217 cases. Effective rate showed 87.5%. Effective rate increased by using high dose rates irradiation with small fraction. Effective cases in relieving pain had longer survival than less ones. 26 cases which could not walk due to spinal cord paresis were treated by irradiation only or irradiation with decompression surgery. Walk recovery rate was 33% by radiation treatment only, on the other hand, by treatment with decompression surgery, it was 20%. Regarding as side effect, radiation myelopathy hardly occurred about 50 Gy (conventional irradiation method). We think if longer survival time is hoped, about 50 Gy is needed.

Iatrogenic vocal cord paralysis is a well-publicized complication of thyroid and parathyroid operations. Less appreciated is the improvement of vocal cord function after resection of a thyroid or parathyroid tumor. Over the last 22 years, 14 patients presented with vocal cord paresis in the presence of thyroid or parathyroid tumors. Of these 14 patients, nine had complete resolution of paresis following resection of the thyroid or parathyroid tumors: three had a thyroid carcinoma impinging upon the nerve, three had large colloid goiters, two had a follicular adenoma and one had a parathyroid adenoma displacing the nerve. In five of the 14 patients the vocal cord paralysis persisted after operation. In three, the pathology accounted for the vocal cord paralysis and was not amenable to operative improvement: one patient had an unresectable anaplastic thyroid carcinoma, one patient had long-standing idiopathic unilateral vocal cord paralysis, and one patient had laryngeal adenoid cystic carcinoma with thyroid invasion. The fourth patient had an extensive thyroid hemangioma. The paralysis persisted after resection. The fifth patient had long-standing idiopathic vocal cord palsy. A preoperative vocal cord paresis in a patient with thyroid or parathyroid disease does not indicate permanent loss of recurrent nerve function, even in the presence of carcinoma. In this series, vocal cord function was restored in 9 of 10 patients with resectable thyroid or parathyroid tumors.

Paresis progressing to paralysis was caused by a neuroepithelioma located at the level of the L1-L2 interspace in a 7 1/2-year-old Golden Retriever. This tumor has never been reported in a dog more than 3 years old. The possibility of a neuroepithelioma should be considered in the differential diagnosis of paresis/paralysis in older dogs.

A case of intracranial hypoglossal neurinoma is reported. A 32-year-old man with a history of unsteady gait and headache for one and a half years was admitted to our hospital on September 23, 1983. Neurological findings on admission were nystagmus toward the left, left IXth and Xth cranial nerve paresis, left cerebellar signs, paresthesia of the left upper and lower extremities on neck flexion, and left pyramidal signs. Atrophy or fasciculation of the tongue was not noted. Computed tomography demonstrated a large isodensity and partially low density mass in the posterior fossa which was markedly enhanced and sharply margined with contrast medium. The tumor extended 45 mm over the edge of the foramen magnum. The maximum size was 45 mm X 40 mm. The coronal and sagittal reconstruction CT scan clearly demonstrated the attachment and extension of the tumor. Enlargement of the hypoglossal canal was clarified by changing the window level, window width and using 2 mm slice CT scan. Anterior-posterior x-ray view of the skull tomography showed enlargement of the hypoglossal canal, as indicated by the CT scan. The left hypoglossal canal was 7 mm and right was 3 mm in diameter. Vertebral angiography demonstrated that the tumor was located in the left posterior fossa, but no tumor stain appeared. This patient did not have XIIth cranial nerve palsy, but the neuroradiological findings strongly suggested a hypoglossal neurinoma, especially the findings of the CT scan and the anterior-posterior x-ray view of the skull tomography. On October 5, suboccipital craniotomy with Cl laminectomy was performed in prone position.(ABSTRACT TRUNCATED AT 250 WORDS)
