Endoscopy-Aided Combined Intraoral and Cervical Approach for a Huge Parapharyngeal Benign Tumor.

We introduce here our surgical approach for the removal of a huge parapharyngeal tumor in 3 cases. Surgery was done under general anesthesia using transnasal intubation. Transoral manipulation was performed first.

Radiotherapy with fraction size of 2.25 Gy in T1-2 laryngeal and hypopharyngeal cancer.

This study was carried out to evaluate the influence of fraction size 2.25 Gy on local control of T1 and T2 laryngeal and hypopharyngeal cancers. Between August 2002 and December 2010, 80 patients with T1 and T2 laryngeal or hypopharyngeal cancers were treated with definitive radiotherapy with a fraction size of 2.

Bacterial contamination of multiple-use atomizers commonly used in Japan.

Before performing transnasal fiberscopy to observe the nasal cavity, pharynx and larynx in outpatient clinics, nasal anesthetics and vasoconstrictive agents are routinely sprayed into the nares in order to improve patients' comfort. Bacterial contamination of the nozzles of Venturi principle atomizer barrels and their solutions after being used for multiple patients over a long-term period without cleaning is controversial. We evaluated the potential risk of atomizer-associated cross-infection by using atomizers commonly available in Japan that use compressed air to atomize medication.
