JOURNAL RESTRICTED ACCESSThe laryngeal functions in patients with laryngeal or hypopharyngeal cancer treated with concurrent chemoradiotherapy (CCRT) were evaluated. We reviewed the records of 32 patients with resectable stage II to IV squamous cell carcinoma of the larynx or hypopharynx treated with CCRT as a initial treatment between October 1998 and September 2003. A questionnaire survey and measurements of maximum phonation time, GRBAS and range of voice/speaking fundamental frequency were performed, and the method of food intake in the swallowing ability scale and the presence of tracheostoma were assessed for evaluating laryngeal functions after CCRT. After CCRT for laryngeal or hypopharyngeal cancer, the phonatory functions appeared to be preserved in 75%of the patients in terms of sustainability;however, there were some cases presenting hoarseness and narrowed range of voice. Oral intake was possible in most cases (97%) without a history of aspiration pneumonia. In 2 cases, permanent tracheostoma had to be retained. It was concluded that laryngeal functions could be preserved in most cases after CCRT, though the tracheostoma might not be closed in some patients with laryngeal cancer.View full abstractDownload PDF (589K) -

JOURNAL RESTRICTED ACCESSThe effect of acid on respiratory epithelium barrier function is still obscure. We attempted to evaluate the electrical barrier function of the trachea in guinea pigs using an Ussing chamber. We exposed the apical membrane side to hydrochloric acid, and then administered DPC (diphenylamine-2-carboxylic acid), and measured the change in the short-circuit current. Similarly, we measured for amiloride, which is a sodium channel blocker, and for zinc chloride, which is a proton channel blocker. The increase in the short-circuit current after acid exposure was partially inhibited by DPC, amiloride, and zinc chloride, but did not show a significant difference in the case of DPC or amiloride. We also found that the decrease in short-circuit current showed a significant difference for zinc chloride. The acid influenced both the transcellular pathway and the paracellular pathway in the epithelium electrical barrier, and it may also reduce epithelial barrier function.View full abstractDownload PDF (437K) -

JOURNAL RESTRICTED ACCESSToday, head and neck superficial cancer can be diagnosed thanks to improvements in new endoscopic systems such as narrow band imaging (NBI). We treat these superficial cancers by transoral mucosal resection with direct laryngoscope under microscopic view. This method requires adequate view and enough working space to maintain a satisfactory operation field, so it is important to choose an appropriate direct laryngoscope. We investigated the types of direct laryngoscope used in transoral mucosal resections for oropharyngeal and hypopharyngeal superficial cancers. A large-caliber direct laryngoscope enabled us to resect oropharyngeal and hypopharyngeal superficial cancers located at the posterior wall especially, with wide view and satisfactory operability.View full abstractDownload PDF (4966K)

JOURNAL RESTRICTED ACCESSA case of giant hemangioma that extended from the anterior cervical region to the superior mediastinum, with a major axis of 16 cm, is reported.
A 48-year-old female who suffered hoarseness had been diagnosed with hemangioma at another hospital 10 years ago. Recently, she complained of dyspnea caused by a laryngeal lesion during vocalization and was referred to our hospital.
Fiberoptic examination showed a pedunculated tumor with its pedicle on the left arytenoid. The tumor fitted into the supraglottic cavity to induce dyspnea on inhalation during vocalization. MRI examination showed the existence of a giant hemangioma occupying the cervical region to the superior mediastinum reaching to the level of the third thoracic vertebra.
Resection of the pedunculated tumor together with tracheostomy was planned for airway management. However, we confronted unexpected bleeding from the tumor occupying the frontal neck, and the tracheostomy procedure could not be completed, necessitating a second surgical attempt at tumor removal. In the second surgery, the pedunculated tumor was successfully removed by lateral pharyngotomy using peroral intubation modality for postoperative airway management.
Our experience suggests the importance of proper planning of airway management modality for safe and successful surgery on a patient with a large tumor in the trachea.View full abstractDownload PDF (2665K) -

JOURNAL RESTRICTED ACCESSThe patient was an 85-year-old male. He was urgently brought to the emergency department of our hospital because of impaired consciousness and acute respiratory failure. He underwent endotracheal intubation with a diagnosis of CO2 narcosis and was admitted to the hospital. After he was extubated, dysphagia was found. Videofluorography (VF) was performed and abnormal bone proliferation of the anterior longitudinal ligament was noticed in the lateral view of the neck. Forestier disease was diagnosed.
Our hospital does not have an otolaryngology department or head and neck surgery department. Moreover, our orthopedics department does not treat Forestier disease. Therefore, Forestier disease has not gained wide recognition as a differential diagnosis for respiratory disorder or dysphagia. Patients with Forestier disease commonly visit otolaryngology departments with a complaint of hoarseness or dysphagia. However, since they may be transferred to the emergency department of an acute phase hospital due to acute respiratory failure, Forestier disease should be taken into consideration.View full abstractDownload PDF (1391K) -

JOURNAL RESTRICTED ACCESSWe present a case of staged operations for the treatment of esophagotracheal fistula caused by an esophageal foreign body. The patient was a 32-year-old male with congenitally disturbed intelligence. He complained of vomiting and fever for 1 week. He underwent esophagoscopy at the nearest clinic. The esophagoscopy revealed that a cloth cord was obstructing the upper thoracic esophagus. Removal of the cord revealed severe ischemic changes in the esophageal wall and an esophagotracheal fistula in the tracheal membranous portion. Subsequently, the patient was referred to our clinic. First, he underwent a thoracic esophagectomy, patch repair of the tracheal wall defect at the fistula using the pericardium, and omentopexy around the pericardial patch. Esophageal reconstruction with the ileocolon was performed 23 days after the first operation. Anastomotic leakages occurred and were managed by spontaneous tube drainage. The patient was discharged 3 months after the first operation.View full abstractDownload PDF (2442K) -

JOURNAL RESTRICTED ACCESSWe report two cases of intrathoracic adenomatous goiter which were resectable through a cervical collar incision. Case 1:A 75-year-old female presented with a 7 cm-sized mediastinal tumor that displaced the trachea to the right and extended to the level of the aortic arch. Case 2:A 48-year-old male had a 9 cm-sized mediastinal tumor that displaced the trachea to the left and extended to the level of the azygos vein through the back of the left brachiocephalic vein. In both cases, the tumor was successfully removed through a cervical collar incision without complications. Pathological examination revealed an adenomatous goiter.View full abstractDownload PDF (1537K)
