Abstract In conventional bone conduction (BC) devices, a vibrator is typically applied to the mastoid or condyle processes. Recently, however, BC-sound presentations facial parts such as nose have also been investigated. As face among most complex structures in human body, BC sounds presented are likely show different perception and propagation characteristics from those parts. We measured hear...

BACKGROUND A mastoid cavity resulting from a canal wall down mastoidectomy can result in major morbidity for patients due to chronic otorrhea and infection, difficulty with hearing aids and vertigo with temperature changes. Mastoid obliteration with reconstruction of the bony external ear canal recreates the normal anatomy to avoid such morbidity. Few have the studied the quality of life benefi...

This thesis is concerned with the analysis of the mastoid electroencephalogram (EEG) using parametric modelling and neural network techniques in order to assess the vigilance of a human subject. One possible application of this work would be the design of a monitoring system for tracking the transitions within the vigilance continuum. A system for monitoring the vigilance of individuals involve...

OBJECTIVES To present a series of temporal en plaque meningiomas involving the middle ear or mastoid, whose main symptoms suggested a serous otitis media. STUDY DESIGN AND SETTINGS Multicentric retrospective study reviewing clinical records originating from eight tertiary referral centers. MATERIALS AND METHODS The clinical records of 10 patients presenting with signs and symptoms suggestin...

Introduction. Osteoma of the temporal bone is a very uncommon benign tumor of bone. Osteomas may occur in the external auditory canals but are reported to be very rare in the mastoid bone. Case Report. A 36-year-old male presented to our department with a hard swelling behind the right ear diagnosed as osteoma. Complete excision was done through a postauricular approach. Histopathology confirme...
