Our results evaluating the correlations between nasal mucosal and serum levels of antigen-specific IgE indicate that IgE produced in the nasal mucosa affects the IgE levels in the serum, especially the cedar pollen-specific IgE.

We report endonasal ultrasonography (US)-assisted neuroendoscopic transsphenoidal surgery (TSS) in seven patients. With sagittal and coronal US images, internal carotid arteries, anterior cerebral arteries, residual tumor, and lateral ventricles were recognized, and the tumors were removed without leakage of cerebrospinal fluid in patients with pituitary adenoma. US images clearly depicted the carotid arteries, anterior cerebral arteries, middle cerebral arteries, chiasmatic cistern, and residual tumor. Endonasal US images can provide real-time animated information and may help neuroendoscopic TSS, whenever needed during TSS.

Twenty-seven nasal allergy patients suffering from olfactory disturbance were evaluated in

A 59-year-old Japanese woman presented with right visual impairment and tunnel vision. Pituitary gland tumor was diagnosed and nasal endoscopic transsphenoidal surgery was performed. Following partial removal of the posterior wall of the sphenoid sinus and extension of the ultrasonography probe to contact the dura mater, the bilateral carotid arteries and the pituitary gland tumor were clearly visualized. The ultrasonography image became clearer when the sphenoid sinus was filled with physiological saline. Histopathological analysis of the resected specimen revealed a pituitary adenoma. Ultrasonography was particularly useful in depicting the arteries, showing the tumor at the nasal endoscopic transsphenoidal surgery.
