JOURNAL FREE ACCESSThis report is the result of autonomic function tests of patients complaining of foreign-body sensation in the throat, visited at department of Otolaryngology of Fujita-Gakuen University from January 1983 through June 1984.
The subjects were subsequently selected 193 patients, 91 males and 102 females.
Quantitative autonomic function test was examined the value of coefficient of variation of R-R interval in ECG by kageyama's method.
At the same time, CMI test was performed in order to investigate their psychological factor.
The results are obtained as follows:
1. Patients' value of CV were tended to lower than normal subjects, in other words, parasympathetic dysfunction were observed in 24.7% of all patients.
2. 36.9% of all patients were classified III or IV group in CMI test.
3. The closed relation between psychological factor and parasympathetic function was not revealed in this study under CV and CMI test.View full abstractDownload PDF (859K) -

JOURNAL FREE ACCESSThirteen cases of vocal cord paralysis were experienced at our hospital during the last 4 years from 1981 to 1985. All cases were diagnosed by means of the flexible fiberscopy of the larynx. The direct laryngoscopic study was performed under general anesthesia for another one case for the definite diagnosis. Only few cases of vocal cord paralysis in children have been reported in Japan. Vocal cord paralysis was not an uncommon finding in congenital laryngeal diseases. Among those, laryngomalacia was the most common, followed by vocal cord paralysis and then by subglottic stenosis.
Nine cases had a bilateral vocal cord paralysis which was caused by central nervous system diseases such as hydrocephalus, meningocele and so on in three cases, tracheoesophageal fistula in one case, VSD in one case, genetic origin (13q-) in one case, mitochondrial myopathy in one case and idiopathic in two cases. Unilateral vocal cord paralysis was observed in four cases and it was caused by TEF, right microtie and VII palsy in one case, VSD in one case and postoperation (TEF, cystic hygrom) in two cases.
Five cases of bilateral vocal cord paralysis improved their laryngeal function with growing. Two cases underwent tracheotomy and have been canulated. Remaining two cases passed away. Three patients with unilateral vocal cord paralysis recovered as they grew up, however the tracheotomy was required in one case.
These results indicate that the recovery of the mobility of vocal cord is expected in patients with bilateral paralysis as well as with unilateral paralysis, however, intensive care is essential for those patients.
ABR (auditory brainstem reflex) tests were performed on three patients and two of them revealed no abnormality. Other patient showed that the duration of I and III was 2.6 msec and it was longer than normal value.View full abstractDownload PDF (3135K) -

JOURNAL FREE ACCESSEver since the successful visualization of the vibratory mode of the vocal folds by Oertel in 1895, laryngostroboscopy has been widely applied in the clinical management of dysphonias. However, in order to keep a record of the observed stroboscopic images, a very highly sensitive video camera was needed, and such cameras were considerably heavy and expensive. The purpose of this paper is to introduce a method of videotaping the vocal fold vibration obtained by the newly developed laryngo-stroboscope (Nagashima LS-3A) using a rigid telescope (Nagashima SFT-1) or a flexible fiberscope (Machida FLT-6) and a reasonably priced color video camera for family usage (JVC GX-N7).
Thanks to recent technological advances, compact and lightweight color cameras with sufficient sensitivity and capable of producing suitable afterimages for video laryngo-stroboscopy have been available. Besides, this new stroboscope provides continuous slow-motion images of the vocal fold vibration with quantitatively constant slow-motion ratio generated by the digital phase shift circuit, and those stroboscopic images simultaneously follow the voice pitch fluctuations.
Magnified color slow-motion images of the vocal fold vibration obtained by this method are of high quality and of great value for evaluation and documentation of various laryngeal disorders in the field of phono-surgery.View full abstractDownload PDF (6747K) -

JOURNAL FREE ACCESSHistochemical studies of the membranous glycoprotein with horse-raddish peroxidase conjugated lectins were performed on 3 cases of normal laryngeal mucosa, which were obtained operativelly from the patients with hypopharyngeal cancer, and on 13 cases of vocal cord polyps extirpated micro-laryngo-surgery.
The results obtained were as follows:
1) In stratified squamous epithelium of normal vocal cord, basal and keratinezed stratum differed from the middle stratum lacking in affinity for Ulex europeus agglutinin-I (UEA-I). And the staining with peanut agglutinin (PNA) showed specific binding to the spinous and lower granular layer.
2) In stratified squamous epithelium of vocal cord polyps, they were classified into the following three types according to thier staining features with both lectins. a) UEA-I binded strongly to the upper spinous and granular cells. Some cells of the granular layer showed variable intensity ranging from lightly to strongly positive staining with PNA. Both of edematous and fibrous changes were observed in the stroma of these polyps. b) All cell layers except for basal layer were stained with UEA-I. The spinous layer and some cells of the granular layer were stained with PNA. In these polyps, edematous stroma was observed. c) Inter-cellular staining of the lower spinous layer showed specific feature to UEA-I. The basal and lower spinous layers were stained with PNA. Fibrin precipitation, hemorrhage and plasma infiltration were shown in the stroma of these polyps.
These data may strongly suggest that expression of membranous glycoprotein in epithelium differs according to the maturation of cells from the basal cell to the more mature keratinocyte, and also indicate that lectins may be used as marker in various stages of normal and abnormal differentiation.View full abstractDownload PDF (5944K) -

JOURNAL FREE ACCESSSulfur dioxide (SO2) is one of the main air pollutions. In the present study, twenty eight adult rabbits, which were devided to six experimental groups, were exposed to 20ppm of 502 for four consecutive weeks (four hours per day). 200mg/kg of carbocysteine was administered to four groups before, during, during and after, or after exposure to SO2. The ciliary activities and epithelial structure of the tracheal mucosa were examined at 24th hour in three groups and at 14th day in three groups after cessation of SO2 exposure. The ciliary activities were examined according to the direct and quantitative photo-electric method of Ohashi and Nakai. Epithelial structure was observed by scanning and transmission electron microscopy.
The following results were derived from the present observations: The tracheal mucosa obtained 24 hours after cessation of SO2 exposure revealed severely deteriorated ciliary activities and various morphological changes including decreased number of ciliated cells, and cytoplasm protuberances of epithelial cells. Recovery process of the ciliary activities and epithelial structure, if not completely, was observed 2 weeks after the exposure period. In addition, it was elucidated that administration of carbocysteine could decrease SO2 induced damages on tracheal mucociliary system as well as accelerate the recovery process of the tracheal mucosa exposed to SO2.
To sum up, it was established that SO2 affects mucociliary system of tracheal mucosa functionally as well as morphologically and that carbocysteine might have clinical benefit for some respiratory diseases.View full abstractDownload PDF (8872K) -

JOURNAL FREE ACCESSNutrient vessels of the trachea and microcirculation of tracheal wall were investigated using vascular casts in rabbits. Generally, nutrient vessels supplying the right half of the trachea were noted to consist of the right superior thyroid artery branching off from the right carotic artery and the right supreme intercostal artery arising from the right subclavian artery, and those supplying the left half consist of two branches from the left carotic artery, i. e. the left superior thyroid artery and the direct ramus to the trachea. On each side of the trachea, these vascular branches were mutually anastomosed to form the right and left tracheoesophageal artery.
Scanning electron microscopic observations were made of tracheal specimens to delineate the morphology of microcirculation therein.
The observation revealed blood vessels which course between neighboring tracheal cartilages, namely tracheal annular ligaments, and enter the tracheal wall.
When viewed from the mucosal aspect of the tracheal lumen, there were capillary plexus distributed in the superficial layer, under which were seen venus plexus; hence a distinct bistratal structure. Arteries were seen coursing fairly lineally between veins. The arteries, veins and capillaries showed intricate anastomoses in all three dimensions within the tracheal wall. The blood vessels in the tracheal wall eventually were noted to form a tubular meshwork of vessels.View full abstractDownload PDF (9062K) -

JOURNAL FREE ACCESSRecently, tracheostomy has been utilized widely, both in critical and intensive care patients, as a means of providing more secured airways, especially for those who require intensive and long-term respiratory care. In brief, tracheostomy-once considered an emergency procedure-has not become one of the elective procedures for such patients.
However, tracheostomy complications such as bleeding, infection, emphysema, granulations, tracheal stenosis and other post-tracheostomy complications still are encountered in some cases even in skilled and experienced hands.
Among 210 of our recent tracheostomy cases, there were four most informative cases of tracheostomy complications encountered during tracheostomy and in the post-tracheostomy period, suggesting the importance of proper selection of the cannula, atraumatic technique, fixation and position of the cannula, and prevention of post-operative granulation formation. In a fifth and very unusual case, a suture was accidentally swallowed and lodged at the esophageal orifice and remained until routine post-tracheostomy X-ray taken approximately 4 weeks later.
The carefully planned and practiced tracheostomy with endotracheal tube in place under optimal anesthetic state would be the choice in avoiding such unfavorable complications.View full abstractDownload PDF (6560K) -

JOURNAL FREE ACCESSA case of chondrosarcoma arising in the thyroid cartilage was reported. A 53-year-old female consulted our clinic because of hoarseness, mild dyspnea and tumor formation in the anterior neck. Palpation showed a bossellated, bony hard, 3.5×2.5cm, mass in the right anterior neck which moved on swallowing. Laryngoscopy revealed right vocal cord paralysis and a subglottic mass. Cervical X-ray and xeroradiogram showed a well circumscribed mass in the larynx with coarse mottled calcification. Thyroid scintigram revealed a space occupied lesion in the right upper lobe. The total laryngectomy was indicated to remove the tumor. The tumor was found to arise in the right ala of the thyroid cartilage. The pathological diagnosis was low grade chondrosarcoma.
The etiology, diagnosis and management of chondrosarcoma of the larynx were reviewed and discussed.View full abstractDownload PDF (4412K) -
