Advantage of Extended Craniofacial Resection for Advanced Malignant Tumors of the Nasal Cavity and Paranasal Sinuses: Long-Term Outcome and Surgical Management.

Objective: Craniofacial resection (CFR) for advanced sinonasal malignant tumors (SNMTs) is mandatory for radical resection. Surgeons must be aware of perioperative complications and long-term outcome because this procedure is extremely invasive, especially when the tumor involves the anterior skull base.

Methods: Thirty-eight consecutive surgical patients with advanced SNMT of T4 stage or Kadish stage C (31 men and 7 women; mean age, 55 years; range: 19-76 years) treated with CFR in the past 28 years were followed up for 59.

[Surgical approach of lateral temporal bone resection for treatment of head and neck cancer with invasion surrounding the jugular foramen].

We herein present a review of the surgical approach of lateral temporal bone resection (LTBR) in the treatment of 5 cases of head and neck cancers invading the jugular foramen between 2008 to 2013. The patients comprised 3 males and 2 females with ages ranging from 25 to 76 and observation times were between 13 and 22 months. In this study we reviewed the method of operation and treatment.

[A clinical study on cervical tuberculous lymphadenitis: the position of a low invasive needle aspiration procedure for the diagnosis of cervical tuberculous lymphadenitis].

Objective: The diagnosis of cervical tuberculous lymphadenitis has been performed by histological examination using excisional biopsy specimens. However a non-invasive diagnostic procedure alternative to invasive excisional biopsy has been required and fine needle aspiration cytology as well the polymerase chain reaction (PCR) technique have become useful modalities. The aim of this study was to clarify the effectiveness of needle aspiration as a less invasive and more rapid diagnostic procedure than excisional biopsy.

Evaluation of overall tumor cellularity after neoadjuvant chemotherapy in patient with locally advanced hypopharyngeal cancer.

The aim of this study is to clarify the prognostic value of the pathological overall tumor cellularity after neoadjuvant chemotherapy for locally advanced hypopharyngeal cancer. In consecutive series of 45 operable patients with locally advanced hypopharyngeal cancer, neoadjuvant chemotherapy by cisplatin and 5-fluorouracil was administered. Pathological image analysis was performed in 30 patients using the large cross-section specimen after total resection to evaluate the overall tumor cellularity.

[Clinical study of cervical lymph node metastasis in maxillary cancer patients].

The clinical characteristics of lymph node metastasis in maxillary cancer patients were analyzed. Thirty-eight (23%) of the 166 patients who received intial treatment at Kurume University Hospital between 1978 and 2003 had cervical lymph node metastasis at the time of diagnosis. The disease-specific 5-year survival rate was 63% in the lymph node metastasis negative group and 18% in the lymph node metastasis positive group (p<0.

[Autologous tumor-specific immunotherapy for recurrent malignant melanoma of the nasal cavity].

Malignant melanoma usually occurs in tissues containing large numbers of melanocytes, such as the skin, mucosa and eye, and is one of the most highly malignant tumors known. No satisfactory treatment results have ever been reported. We report here an effective course of immunotherapy consisting of the local injection and intra-venous administration of autologous tumor-cell-stimulated cytotoxic T lymphocytes in a patient with recurrent malignant melanoma.

Age related changes in the distribution of laryngeal glands in the human adult larynx.

Objective: To understand the defense status of glandular tissue in the human adult larynx, we examined the glandular distribution, concentration and the ratio of the mucous glands in the subglottic and supraglottic larynx.

Methods: One-hundred and seven adult larynges were examined. The area of the mucosa and glands were measured using an image analyzing system.
