JOURNAL FREE ACCESSIt is widely accepted that mast cells play the most important role in type I allergic reactions, and that mast cells can be divided into mucosal mast cells (MMCs) and connective tissue mast cells (CTMCs). MMCs are sensitive to formaldehyde fixation, which CTMCs are resistant to.
We investigated the distribution of mast cells in human laryngeal mucosa. The mucosa was obtained from four normal larynxes resected due to carcinoma of the mesopharynx or oral cavity. Sections obtained from the epiglottis, vocal cord and the arytenoid portion of the larynx were stained with toluidine blue after being fixed with a 10% buffered-formalin solution or Carnoy's fixative.
The number of formalin-sensitive mast cells was significantly greater than that of formalin-resistant mast cells in the epithelial layer and the shallow layer of the lamina propria (less than 50 μm from the basement membrane) in the arytenoid portion of the larynx. On the other hand, the difference between the number of formalin-sensitive mast cells and that of formalin-resistant mast cells was not significant in the epiglottis or the vocal cord mucosa.
This result demonstrates the presence of MMCs in the arytenoid portion of the larynx, and suggests that Type I allergies are induced in the arytenoid portion of the larynx.View full abstractDownload PDF (2828K) -

JOURNAL FREE ACCESSPostintubation granulomas of the larynx are one of the possible complications following tracheal intubation. Though there have been many reports on their etiology, clinical cause and management, there have been few reports dealings with children.
Between April 1989 and March 1994 we have seen postintubation granulomas in six children aged 11 months to 15 years.
1) Their chief complaints were hoarseness, dysphonia, dyspnea and decannulation.
2) Four of the children had a systemic complication. Two of these four children had severe cerebral palsy.
3) In four children intubation was necessary for the respiratory control post-operation. In the others, intubation was carried out for respiratory control only because of their disease.
4) The intubation lasted for from 2 days to 4 weeks.
5) Conservation treatment of laryngeal nebulization with steroid and epinephrine was effective. In four children the size of the granulomas remarkably decreased after the laryngeal nebulization, but in the other two children with cerebral palsy it was not so effective. For these children, tracheostomies were performed because of the decannulation.
6) In children severely mentally or physically handicapped, it is considered granulomas of the larynx can easily occur.
We think that an abnormally hypertonic condition of the muscles and a frequent over extensive position of the head and neck will be important to reveal the etiology of granulomas of the larynx.View full abstractDownload PDF (2580K) -

JOURNAL FREE ACCESSManometric studies were carried out on six normal subjects and 23 patients with thoracic esophageal carcinoma who underwent esophageal reconstruction. The reconstruction routes were as follows: intrathoracic route (6 patients), retrosternal route (9 patients) and antethoracic route (8 patients). There was no difference between the control subjects and the intrathoracic route patients in terms of resting pressure and swallowing pressure. In the retrosternal route and antethoracic route patients, the resting pressure was lower in the upper high pressure zone and higher in the cervical esophagus than that of the controls. In these patients the swallowing pressure curve was also quite different from that of the controls. As far as manometric studies are concerned, the intrathoracic route is thus the best way of reconstructing the esophagus for thoracic esophageal carcinoma.View full abstractDownload PDF (1885K) -

JOURNAL FREE ACCESSA case of granular cell tumor of the vocal cord in a 13-year-old child, who complained of a horse voice, was reported with a review of the literature. This type of tumor is rare in children. The tumor was found in the anterior 1/3 of the left vocal cord, was milky-white in color and covered by smooth epithelium. It looked like a vocal cord cyst and was successfully removed under microlaryngoscopy. No recurrence has been noted. The removed tumor was solid and characteristically hard. The diagnosis was confirmed histologically.View full abstractDownload PDF (4328K) -

JOURNAL FREE ACCESSA rare case of throat burn caused by the accidental inhalation of the flame of a toy firework was reported. A 13-year-old boy omplained of a sore throat with difficulty in swallowing and moderate hoarseness after meeting with the accident. A firework scaffold fell suddenly after ignition, and part of its flame entered the mouth of this boy who was standing 20m distant.
When he visited our clinic, an indirect laryngoscopy showed that the epiglottis and the bilateral arytenoid regions were hyperemic and edematously swollen. He was under medical treatment of hydrocortisone sodium succinate and antibiotics. It was concluded that this throat burn was a thermal injury caused by the inhalation of a flame, probably of a paper casing. Two years observation revealed no cicatrical contracture.View full abstractDownload PDF (2372K) -

JOURNAL FREE ACCESSTwo patients with a large cavernous hemangioma are reported. One was an 11-year-oldmale complaining of a slowly growing cervical mass without tenderness. Indirect laryngeal examination showed multiple dark purple nodules on the right pyriform sinus and larynx. MRI examination revealed a tumor located on the larynx, the hypopharynx and the right neck. The mass was removed surgically with a right cervical incision. Two weeks later, the residual hemangioma of the larynx was vaporized by a CO2 laser through a direct laryngoscope.
The second patient, a 55-year-old female, complained of throat discomfort. An irregular-surfaced mass was found by indirect laryngoscopy. The tumor occupied the left pyriform sinus, aryglottic fold, false cord and epiglottis. It was found to have deeply invaded the left vocal cord under MRI examination. The tumor was removed by a lateral pharyngotomy and laryngofissure.View full abstractDownload PDF (4604K) -

JOURNAL FREE ACCESSAn 84-year-old female and a 76-year-old female with retropharyngeal hematoma are reported. Both patients visited our hospital because of dyspnea and dysphagia following neck injury. In both patients, the hematoma developed in the retropharyngeal space from the cranial base to the superior mediastinum. The first case underwent in emergent tracheostomy, and was fed with a nasogastric tube. Her hematoma regressed spontaneously in about two weeks. The second case did not need a tracheostomy, but required intravenous hyperalimentation, and her hematoma disappeared itself in about 25 days.View full abstractDownload PDF (3992K) -

JOURNAL FREE ACCESSTwo patients, whose previous procedures for obstructive sleep apnea syndrome had made no improvement in their symptoms, were successfully treated with revision surgeries of uvulopalatopharyngoplasty (UPPP) performed in our clinic.
The first patient was a 30-year-old male who had his initial UPPP done elsewhere five years ago. This patient underwent a revision of the UPPP and septoplasty this time. The other patient was a 53-year-old male whose UPPP was performed elsewhere 20 years ago by an ENT surgeon. his patient was treated with a revision of the UPPP and a midline glossectomy using a CO2 laser at our institute.
In evaluating these patients, it was determined that a failure to recognize the distance between the soft palate and posterior wall of the pharynx in the initial surgery was the cause of the undesirable result in the first patient, and that the development of a nasopharyngeal stenosis secondary to the adhesion of the soft palate was the etiological factor in the second case. A septal deformity and an abnormal base of the tongue have also contributed to the problems of these patients, respectively. Making an accurate diagnosis cannot be overemphasized in the treatment of obstructive sleep apnea syndrome.View full abstractDownload PDF (5025K) -

JOURNAL FREE ACCESSWe encountered a case having cutaneous neurofibromatosis associated with intestinal leiomyosarcoma and hypopharyngeal carcinoma. The patient was a 57-year-old female, who was hospitalized at Dokkyo University Hospital in September 1993 complaining of dysphagia. Various tests were made, and a tumor was found at the posterior wall of the right piriformis sinus. As a result of a punch biopsy from the hypopharynx, the patient was diagnosed as having “well-differentiated squamous cell carcinoma. ”By radiotherapy of the hypopharynx, her general condition was temporarily improved, but she underwent an operation for a recurrence of the dysphagia on May 30, 1994. Histopathologically, a three-tumor duplication was found after the operation. This consisted of cutaneous neurofibromatosis, leiomyosarcoma of the small intestine and well-differentiated squamous cell carcinoma of the hypopharynx. Tumor duplication is often seen in neurofibromatosis. Careful observation of patients with von Recklinghausen's disease is necessary.View full abstractDownload PDF (6092K) -

JOURNAL FREE ACCESSSymptomatic gastric metastasis from carcinoma of the lung is extremely rare, so we report a case of metastatic gastric cancer. A 64-year-old man was admitted to the First Department of Internal Medicine, Nihon University School of Medicine, in July 1992, in order to treated for primary small-cell lung cancer and was given chemotherapy at our hospital. Afterwards, he complained of hemosputum. A chest roentgenogram showed a small tumorlike shadow in the left upper lung field, and we diagnosed recurrence. The patient was admitted to our hospital and was treated with chemotherapy again. During the therapy, he complained of gastrointestinal symptoms such as nausea. Vomitting and anemia were observed continuously. An upper-gastrointestinal endoscopic examination showed that multiple, elevated submucosal tumors with central depressions were found on the upper gastric body. Biopsy showed a small-cell carcinoma identical with the lung cancer. We concluded that it is necessary to proceed to an upper-gastrointestinal endoscopic examination whenever gastrointestinal symptoms and anemia are observed continuously.View full abstractDownload PDF (6010K) -

JOURNAL FREE ACCESSUsing an intraluminal ultrasonic system, a radial scan-type catheter of 20 MHz was directly inserted into the intralaryngeal lumen to experimentally obtain a horizontal image of vocal fold. Collagen was injected into vocal fold unilaterally, and this was compared with the normal side. A histological specimen was also prepared and compared with thehorizontalsection image.
On the image of the vocal fold, the lamina propria and epithelium were notedin a line, and the injected collagen was identified as a hyperechoic area. The vocalis muscle showed hypoechoic image.
These results suggest that intralaryngeal ultrasonography can be useful in clinical application for detecting tumor involvement in the vocal folds and as a guide during injection therapy.View full abstractDownload PDF (3267K) -

JOURNAL FREE ACCESSIn some cases of pyriform sinus cancer, it is possible to preserve laryngeal function by partial laryngopharyngectomy. We reported a case of right pyriform sinus cancer involving the aryepiglottic fold, for which hemicricolaryngopharyngectomy and laryngeal reconstruction with an auriclar graft were performed.
The hemilarynx, ipsilateral pyriform sinus, and half of the cricoid ring were resected according to the method of hemicricolaryngopharyngectomy reported by Krespi and Sisson. The pharynx was reconstructed primarily by suturing. At first, we tried to reconstruct the larynx with a free retroauricular chondrocutaneous flap. However, because of a vasospasm, we had to give up a primary laryngeal reconstruction. Therefore, the remaining larynx was kept open as a laryngocutaneous fistula, and a retroauricular chondrocutaneous flap was grafted onto the left forearm to make a prefabricated flap for the preparation of secondary reconstruction of the larynx. In addition, a laryngeal suspension to the hyoid bone and cricopharyngeal myotomy were carried out to avoid postoperative aspiration.
In the second stage of the operation, the left forearm flap with the auricle was grafted onto the larynx to reconstruct the laryngeal framework and glottis. A bulging part of the autihelix was sutured at the same level with the remaining vocal fold to obtain sufficient glottal closure.
Four weeks after the second operation, the tracheostoma could be closed. Dyspnea was not seen and phonation was good. Although slight aspiration occurred when drinking liquid quickly, laryngeal functions was satisfactory. Two courses of postoperative anticancer chemotherapy were administrated, and the patient remained free from tumor for about eleven months after the resection.View full abstractDownload PDF (4733K)
