Adenocarcinomas are uncommon among sinonasal malignant tumors, which are usually squamous cell carcinomas. Intestinal-type adenocarcinomas （ITACs）, which histologically resemble colorectal adenocarcinomas, are rare among sinonasal malignant tumors, with a frequency of 4％. There are very few case reports of ITACs in Japan. Although a search of the g...

We report a case of retropharyngeal venous malformation that was completely resected by minimally invasive surgery. The patient was a 66-year-old male who was referred to our hospital with a pharyngeal tumor, diagnosed by gastroscopy ; the patient complained of pharyngeal discomfort. In the initial assessment we observed a venous malformation indic...

This study aimed to investigate the usefulness of intraluminal Pco2 (Pico2) monitoring by air tonometry for the assessment of the vascular condition of the transferred jejunum after surgery for hypopharyngeal cancer. Pico2 in the transplanted jejunum of 24 patients was monitored using air tonometry after radical surgery for hypopharyngeal cancer fr...

We experienced a huge vascular-rich paraganglioma in the base of skull in the parapharyngeal space, and we removed the tumor by mandibular swing approach. After the operation, dysphagia due to the cranial nerve (IX, X, XI) paralysis had been developed, but it was improved by rehabilitation. 3D-CT angiography was useful for the simulation of the ope...

We treated 137 patients with well-differentiated thyroid carcinoma at our hospital from 2002 to 2012. This paper clarifies the high-risk group based on prognostic factors of recurrence. The 5-year survival rate for patients with thyroid carcinoma was 94.9%. Recurrence occurred in 25 cases (18.2%). The factors of patient’s age and sex were not relat...

We present a case of pharyngeal perforation caused by gastrointestinal endoscopy that was successfully repaired with transoral mucosal sutures. This is the first report of a transoral surgical closure of a perforation caused by an endoscope. We describe the repair procedure, the necessary equipment, and the effectiveness of suturing pharyngeal perf...

Many approaches to the parapharyngeal space have been reported. However, few reports describe parapharyngeal space tumours and the best surgical approach to these tumours. We retrospectively examined the surgical approaches we used to resect 22 parapharyngeal space tumours. In order to determine the best surgical approach for each tumour, we first...

Despite its rarity, information on the diagnosis of parapharyngeal space tumors such as through imaging and aspiration biopsy cytology, is slowly accumulating. Little detailed examination has been conducted, however, on surgical approach, complications, and sequelae. We report the results of a retrospective review of 27 patients with primary paraph...

Carcinomas of the ethmoid, frontal, or maxillary sinuses sometimes invade the anterior skull base. It is necessary to perform en-bloc resection for this invasive carcinoma according to the concepts of surgical treatment for head and neck cancer. The anterior skull base consists of two parts, the orbital roof as the lateral portion and the roofs of...

The procedure for reconstruction of the extensive defect after total glossectomy with total laryngectomy has not been standardised so far. We have devised a new method in which a free jejunal patch is extended to a sigmoid-shaped form specifically optimised for reconstruction of the defect that consists of the entire floor of the mouth and the ante...

The choices for practical monitoring of free jejunal transfer have been quite limited because of its own characteristics, such as buried form, lack of skin surface, and the structure of a hollow viscous tract. Physiologically, it is known that tissue hypoxia caused by compromised perfusion leads to an increase of partial pressure of carbon dioxide...

抄録 Recent advances in the diagnosis and treatment of head and neck malignancies seem to have increased the chances of finding multiple primary cancers. Of the 220 patients with head and neck malignancies, treated in Shizuoka Red Cross Hospital from November, 1989 to October, 1994, 23 (10.5%) had multiple primary malignancies. The mean age of the 23...

A 57-year-old housewife complaining of choking was admitted to our hospital. Fiberscopic examination revealed a white tumor with a smooth surface and a slight hypervascularity below the vocal cords. A cervical X-ray examination taken from the lateral view revealed that the tumor was located between the area just beneath the vocal cords and the four...

Skull base surgery has been performed in 16 cases for en bloc resection of the nasal cavity and paranasal sinus carcinoma invading the anterior and middle skull base in our department. The surgical approach to skull base surgery is mainly a combined craniofacial approach, which includes craniotomy via a coronal incision intracranially and a transfa...
