The authors describe the case of a 57-year-old female who developed subrachnoid hemorrhage secondary to rupture of posteriorly projecting, high placed aneurysm of the proximal posterior cerebral artry. This aneurysm was treated easily and successfully with the zygomatic temporopolar approach which was modification of the temporopolar approach proposed by Sano by detaching the zygomatic arch to get a wide and flexible operating field.

Chordomas are maligaant tumors which arise in the remnants of the embryonic notochord, and exhibit a definite predilection for the extremes of the spinal axis, the great majority arising either in the basioccipital or in the sacrococcy geal regions. Particularly, complete surgical removal is almost impossible, therefore, local recurrence after the surgical removal of this tumor is common or rule. This report describes a csse of chordoma arising sacrococcygeal region treated with block resection.

This study aimed at examining speech defects of open bite patients, which were analized in terms of formant frequency for vowels and word pronunciation length for consonants. In addition, the upper and lower lip (perioral m.) activity was tested by the EMG. The tongue force was measured by the strain gauge, and the speech discrimination test was carried out. One experimental group and one control group were used for this study and they were respectively composed of six female openbite patients and six normal-occlusion females. Eight monophthongs, two fricatives and two affricatives were chosen for speech analysis. Speeches of the above-mentioned groups were recorded and then analized by the ILS/PC-I software. Four hundred most frequently used monosyllables were also chosen for discrimination score. Openbite patients showed the following characteristics: 1. Abnormality in case of /a/, /epsilon/, /e/, /i/ F2 and /e/, /a/ F1. 2. Significantly elongated length in their pronunciation of /h/ and /Ch/ and somewhat elongated length also in their pronunciation of /s/ and /c/. 3. Significant upper lip activity according to the EMG test during pronunciation of the bilabial consonants. 4. Relatively weak tongue force according to the strain gauge measurement. 5. According to the speech discrimination test, high rate of misarticulation in case of (a) initial /p/ /s'/ and /ts'/, (b) /a/, /epsilon/, /e/, /je/, /o/, /phi/, /jo/, /u/, /we/, and /i/ (c) final /eta/.

The study was undertaken to ascertain the speech defect of patients with malocclusion, especrally of poenbite patients, by means of the spectral analysis method. The expermental group was composed of ten female openbite patients and their mean age was 13.8 yrs. The control group was also composed of ten female girls ans then mean was 13.7 yrs. As for the speech materisl, eight Korean monphthrongs ans two Korean fricatives and two affricatives were used Speeches were recorded and then analyzed by a Kay 7800 drgital sonagraph. Formant frequency level or range was used as a phonemic parameter. The results were as follows. 1. Among Vowels /a/ F1,F3, and F1/F2 showed abnormahty /o/and/omega/F2,F2-F1 and F1/F2 showed abonrmahty. 2. Among Consonants /s/and/h/ The upper and lower borders of the frequency range showed abnormahty. /f/ The lower border of the ferquency range showed abonormahty. /C(h)/ The upper and lower borders of the frequency range and concentration point showed abonormahty.

Focal cerebral ischemia was made in 20 adult cats by transorbital middle cerebral artery occlusion (MCAO) under pentobarbital anesthesia. Arterial blood gas, systemic arterial blood pressure (SABP), intracranial pressure (ICP), and regional cerebral blood flow (rCBF) on ectosylvian, suprasylvian, and marginal gyrus of the left hemisphere by hydrogen clearance were measured for 30 minutes before and 120 minutes after middle cerebral artery occlusion. Ten animals were treated with 20 mg/kg of pentoxifylline (PTF) and ten animals with 1ml/kg of normal saline as the control group for 30 minutes before and 30 minutes after middle cerebral artery occlusion. There was no beneficial effect of pentoxifylline (Trental(R)) on basal blood flow over left hemisphere before middle cerebral artery occlusion. Regional cerebral blood flow was highly significantly improved on the marginal gyrus (MG) for 90 minutes after middle cerebral artery occlusion, more remarkable for initial 60 minutes (P<0.01), and also significantly restored on suprasylvian gyrus (SSG) for initial 60 minutes by pentoxifylline (P<0.05). However, pentoxifylline failed to improve regional cerebral flow on extosylvian gyrus (ESG) which was considered dense core of infarct area due to middle cerebral artery occlusion in cat. In addition, pentoxifylline had significant hypotensive effect during intravenous administration for 60 minutes (P<0.05). These findings suggest the possibility of pentoxifylline to ameliorate hemorheological property rather than vasodilating effect in the collaterally perfused area around dense infarct.

One-hundred and sixteen patients with hypertensive putaminal hemorrhage(HPH) were followed at least 3 months after the ictus and their outcome was valuated on the basis of activity of daily living and mortality. They were graded according to age, systolic blood pressure, neurological status, and the extension of hematoma, the diameter of long axis and the volume of hematoma calculated by computed tomographic(CT) scans on admission. In general, our results failed to support the view that the surgical treatment is superior to the conservative one in the management of hypertensive putaminal hemorrhage. However, this study showed some surgical advantage in case of hematoma extending to thalamus or hypothalamus with massive ventricular rupture as well as patients with either a hematoma diameter between 5.1 and 7.0 cm or a hematoma volume between 41 and 80 ml.

The role of cerebral revascularization in the treatment of ischemic stroke has been incompletely investigated. Ten patients with middle cerebral artery occlusion or stenosis and four patients with internal carotic artery occlusion or stenosis underwent superficial temporal artery-middle cerebral artery(STA-MCA) bypass surgery in the setting of acute neurological deficits, crescendo transient ischemic attacks(TIA'S), or recent completed stroke(CS). Early STA-MCA anastomosis was remarkably helpful in the setting of acute cerebral ischemia and crescendo TIA'S for their symptomatic relief. In addition, low flow revascularization were performed safely and also contributed to stabilization or slight reduction of the neurological deficit enen in CS. However, further controlled randomized studies are indicated.
