The authors tested the hypothesis that certain maneuvers (neck flexion/extension and head protrusion/retrusion) alter the appearance of the submental area, jawline, and melolabial groove. They used a questionnaire survey of 20 naïve judges who assessed a standardized photograph album of three subjects. The subjects' faces (frontal and lateral views) were photographed in neutral, neck flexion/ex...

Here we propose a novel musical controller which acquires imaging data of the tongue with a two-dimensional medical ultrasound scanner. A computer vision algorithm extracts from the image a discrete tongue shape to control, in realtime, a musical synthesizer and musical effects. We evaluate the mapping space between tongue shape and controller parameters and its expressive characteristics.

The feeding mechanism of Mellita quinquiesperforata (Leske) has been examined in detail. This sand dollar is a deposit feeder, ingesting particles mostly in the range of 100-250 µm. The particles are picked out of the substrate individually by specialized long barrel-tipped podia, which form a narrow palisade surrounding the geniculate spine fields on the oral surface. Selected food items are p...

OBJECTIVES/HYPOTHESIS To describe surgical outcomes and radiographic features of olfactory groove meningiomas treated by excision through the subcranial approach. Special emphasis is placed on paranasal sinus and orbit involvement. STUDY DESIGN Retrospective review of a series of patients. METHODS Nineteen patients underwent excision of olfactory groove meningioma (OGM) via the transglabell...

The olfactory groove schwannoma is a quite rare tumor. We report a case of a 49-year-old woman with an olfactory groove schwannoma attached to the cribriform plate without olfactory dysfunction. She had no specific neurological symptoms other than a headache, and resection of the tumor showed it to be a schwannoma. About 19 months after the operation, a follow-up MRI showed no evidence of tumor...

Introduction Schwannoma of the olfactory groove is an extremely rare tumor that can share a differential diagnosis with meningioma or neuroblastoma. Objectives The authors present a case of giant schwannoma involving the anterior cranial fossa and ethmoid sinuses. Case Report The patient presented with a 30-month history of left nasal obstruction, anosmia, and sporadic ipsilateral bleeding. Com...
