      OBJECTIVES: To clarify the clinical risk factors that aggravate deep neck infection.

      PATIENTS AND METHODS: Sixty-five patients with deep neck infection (abscess or cellulitis), 42 males and 23 females, who were treated at the ear, nose, and throat department in Iwaki Kyoritsu General Hospital in the past 10 years, were retrospectively reviewed. Cases of inflammation of the upper airway including the oral cavity, laryngopharynx, palate tonsil and salivary gland, and cases of lymphadenitis ...

      Second primary malignancies (SPMs) are one of the most critical problems in treating head and neck cancer patients. Our hospital had 742 patients with a diagnosis of malignant head and neck tumors during the five-year period from 2002 to 2006. In this study, we analyzed 360 of those patients who were assumed to have risk factors such as alcohol and tobacco use: 106 oral, 120 laryngeal, 50 oropharyngeal and 84 hypopharyngeal cancer patients. Synchronous SPMs are defined as second cancers ...

      To examine whether genetic factors influence the prognosis of cancer patients, several microsatellite markers were used to determine the allelic loss of certain areas of the genome. Three microsatellite markers, D3S1067, IFNA and D9S171 were used to study the loss of heterozygosity (LOH) of 3p21 and 9p21 in 93 head and neck squamous cell carcinomas. Of 57 informative cases, LOH was detected in 27 of 57 (47%) DNA samples obtained from cancer specimens when at least one marker was used. ...

      Head and neck squamous cell carcinomas (HNSCC) manifest various clinical behaviors according to their origin, i.e., from various parts of the head and neck mucosa. However, genetic factors involved in the carcinogenesis of HNSCC in different tissues have not yet been studied and evaluated. Three hundred and two specimens of HNSCC were characterized for allelic loss of certain areas of the genome, i.e., 3p21, 9p21 and 17p13, and were examined for genetic factors that might correlate with ...

      OBJECTIVE: We sought to assess the efficacy of combined therapy after superselective arterial cisplatin infusion (SACI) therapy to treat the maxillary squamous cell carcinoma.

      STUDY DESIGN: We conducted a retrospective chart review of 50 patients. After completion of two courses of SACI, 25 of the patients were successively treated by concurrent SACI and radiotherapy (AR), while the other 25 patients were treated by surgery with postoperative radiotherapy (ASR).

      RESULTS: Patients with ...

      Leiomyoma usually originates from the uterus and alimentary tract, but in extremely rare cases leiomyoma can appear in the external auditory canal. Here we present a 37-year-old man with right auricular fullness. Preoperative findings suggested benign tumor or cholesteatoma in the right external auditory canal. We performed total resection using an endoauricular approach with transcanal endoscopic ear surgery. Histopathological and immunohistochemistry examination confirmed the diagnosis ...

      Multiple primary cancers were found in 23 of 68 patients (34%) with an index cancer in the oral cavity or pharyngeal area treated in our institute from June 1995 to July 1998. Four cases had triple primary cancers. All 68 cases underwent upper and lower gastrointestinal endoscopy as well as ultrasonography of the liver. Lung CT was performed in cases with abnormal findings on chest roentgenograms. Multiple cancers were found in 5 of 25 oral cavity cases (20%), 6 of 14 mesopharynx cases ...

      Retropharyngeal abscess commonly develops among infants and small children, and is associated with the severe inflammation of the retropharyngeal lymph nodes located in the retropharyngeal space. Retropharyngeal abscess causes cervical pain, swelling, contracture of the neck, and in rare cases inflammatory torticollis, all of which result from an inflammatory process that irritates the cervical muscles, nerves or vertebrae. Here we report a rare case of retropharyngeal abscess with a ...

      Thirty-nine previously untreated patients with squamous cell carcinoma of the oral tongue treated with curative intent in our hospital from 1993 through 1998 are reviewed. Of these patients, those in the early stage (stages I and II) constituted 64%. The over all 5-year survival rate of all the patients was 60%. The 5-year survival rate of the patients with early stage cancers was unsatisfactory (stage I: 73%; II: 56%). This was thought to be related to the absence of elective neck ...

      Inferior laryngeal nerve (ILN), which usually arises from vagus nerve, runs recurrent course and is called recurrent ILN (RILN). Intimate knowledge of normal and anatomic variants of the ILN reduces the risk of nerve injury and vocal cord paralysis in thyroid and parathyroid surgery. The nonrecurrent ILN (NRILN) is a rare nerve anomaly that is associated with a right aberrant subclavian artery. We encountered 2 patients with NRILN during thyroid surgery. Patient 1, a 57-year-old woman, ...

      The aim of this study is to evaluate the results of treatment for hypopharyngeal cancer and indicate the future prospect of the treatment. Seventy-four patients with squamous cell carcinoma of the hypopharynx admitted to Miyagi Cancer Center from 1993 through 2000 are reviewed. Sixty-four patients received radical treatment, and 10 patients received palliative treatment or no treatment. The cancer was advanced (stages III and IV) in 82% of all the patients. The overall 5-year survival ...
