ジャーナル フリーHydroxyl apatite was employed in reconstruction of the laryngotracheal framework in five cases. It was well received in all the cases and there were no foreign body reactions or infections at all. The hydroxyl apatite proved to be an excellent material in reconstructing the laryngotracheal framework, being comparable to an autograft of the cartilage. The use of hydroxyl apatite saves additional surgery.抄録全体を表示PDF形式でダウンロード (15486K) -

ジャーナル フリーNobody can deny that lubrication is one of the factors which influences the phonatory function of the larynx. However, no notable studies on the mechanism of lubrication have ever been carried out. The aim of this study is to evaluate the dynamics on air tract fluid which is involved in lubrication of the larynx by use of excised canine larynges.
From the results obtained, it is revealed that the air tract fluid from subglottic spaces comes up on the glottis at the moment of the onset of phonation.
The fluid from the subglottis is then mixed with the fluid on the supraglottis. Internally, the mixed fluid forms a spindle shaped fluid column, that is “lubricant column” which is rotating on the surface of the glottis. The column rotates always to the constant direction, namely, from the external to internal in the upper part and from the internal to external in the lower part of the column. Outside of the column, along the wall of the laryngeal ventricle a flow is observed, which is directed forward in the anterior surface and backward in the posterior surface of the vocal fold. The flow above mentioned is combined with the column. The column has also a component which runs from both the anterior and posterior to the central area. During phonation, the air tract fluid on the glottis circulates by “lubricant circulation system”.
At the end of the phonation, the column decomposes and mostly flows backward to the subglottis. From these resultes, it is considered that the lubrication of the larynx during phonation is carried out in 3 different phases; start of phonation (phase 1), during phonation (phase 2) and after completion of phonation (phase 3).抄録全体を表示PDF形式でダウンロード (23131K) -

ジャーナル フリーNobody can deny that an aerodynamic power in the subglottis might be converted to an acoustic energy. However, nobody has reported a definite study on relationship between sub- and supragolottic air pressures which must be an reflection of the voice. Hereby, simultaneous measurements of sub- and supraglotttic pressures have been performed by, are of an artificial phonation in excised canine larynges. In addition, as a subparameter, an air flow during phonation has been visualization in order to observe density distribution of air flow itself.
1. Vocal sound wave, sub- and supraglottic air pressures are not affected on by the existence of the false vocal folds.
2. Constant results in subglottic pressure are obtained at any points of subglottic areas so far as the diameter of the subglottic space is same.
3. An amplitude of supraglottic air pressure is higher at the anterior than at the posterior, the increasing period of the supraglottic air pressure is shorter, the decreasing period of the supraglottic air pressure is longer at the anterior than at the posterior.
4. In decreasing period of the supraglottic pressure, remarkable change is not obtained between normal larynx and pathological larynges.
5. The increasing period of the supraglottic pressure is observed at the decreasing period immediately after the peak of the subglottic pressure.
6. The vocal sound wave is considered as one of reflections by the supraglottic air pressure.
7. By the visualization of the air flow at the phonation of the normal larynx, the periodic wave of condensation and rarefaction is obtained, on the other hand the non-periodic air flow is obtained at the phonation of the pathological larynges.抄録全体を表示PDF形式でダウンロード (4373K) -

ジャーナル フリーA 42 years old male, with complaints of dyspnea and dysphagea, was diagnosed as the oral floor phlegmon. A swelling and pain developed on his bilateral cheeks rapidly. He was admitted on April 13, 1985. The emergent tracheostomy and intravenous administration of antibiotics were performed.
The crecipitation, due to the gas, was palpated. This was confirmed by an X-ray examination. The white mass was removed by incision. Bacteriological study of the mass revealed E. coli, β-streptococcus, pseudomonas and so on. Necrotic tissues and pus were drained repeatedly. However, this resulted in the fistural formation to the hypopharynx. The lesion was treated by washing with antibiotics, and healed completely.
Generally, the gas-producing phlegmon is caused with either Clostridium or the diabetic disease. The case was proved neither Clostridium nor metabolic disorder. Such a pathologic condition is very rare in the head and neck region.抄録全体を表示PDF形式でダウンロード (7587K) -

ジャーナル フリーAdenoid cystic carcinoma of the larynx is very rare and only eight cases have been reported in the Japanese literature. None of those reported cases occurred in the subglottic region. In this paper, a case of adenoid cystic carcinoma originating in the subglottic area of the larynx is reported.
A 66-year-old woman developed shortness of breath and respiratory distress. Endoscopy revealed no mass in the larynx and the upper trachea. Sixteen months later, she underwent a neck exploration with excision of the submucosal tissue of the subglottic area. Pathology report was compatible with adenoid cystic carcinoma. The patient underwent a total laryngectomy. She has been well for the last fifteen months with no evidence of recurrence or metastases.抄録全体を表示PDF形式でダウンロード (7609K) -

ジャーナル フリーThe authors encountered 12 cases of thyroid carcinoma invading into the larynx and the trachea in clinic. They were one male and 11 females, and their age was ranged from 48 to 75 years. Histopathological examination revealed papillary carcinoma in 8 cases, follicular carcinoma in one case, anaplastic carcinoma in 2 cases and squamous cell carcinoma in one case. CT scan of the neck and tomography of the larynx and neck were extremely useful to evaluate an extension of the tumor invasion in preoperative examinations. Their prognosis was that 8 patients were alive, 2 patients were died from local tumor recurrence, and the other 2 patients were died from lung metastasis.抄録全体を表示PDF形式でダウンロード (2233K) -

ジャーナル フリーA case of amyloidosis localized in the laryngo-tracheo-bronchial area is reported. The patient was a 30-year-old man who complained of persistent hoarseness of 5 years duration and dyspnea of 3 months duration.
Tracheostomy and subsequent direct laryngoscopy and bronchofiberscopy were done.
These examinations revealed a marked, submucosal thickening of the bilateral false cord, and tracheo-bronchial stenosis with yellowish tumor forming nodules.
Histological examination showed diffuse deposits of homogenous eosinophilic substances.
A polarized microscopic examination with congo-red stain indicated that the material were amyloid.
Because of the extensive deposition of amyloid, surgical resection was impossible. After tracheostomy, his respiratory function was improved.抄録全体を表示PDF形式でダウンロード (6873K) -

ジャーナル フリーThe modality of the treatment of infantile airway stenosis is still controversial, since the surgical interventions to the upper airway of infants may well produce unfavorable effects on their growth. From 1977 to 1985, 9 cases of infantile airway stenosis have been treated with the silicone T-tube in our department. The period of T-tube insertion ranged from 1 to 30 months (average 14 months). In all cases except one who has been followed up, the tube was successfully removed. The silicone is non-inflammatory and granuation tissue has not been formed even in the case whose tube lodging has lasted for 32 months. It was found that minimum size of the T-tube which can maintain the airway patency in infantile airway stenosis was 6mm of outer diameter (4mm of inner diameter). It thus appears that use of silicone T-tube is simple and safe measures for the treatment of airway stenosis in infants of less than 3 years old.抄録全体を表示PDF形式でダウンロード (4647K) -
