Facial paralysis is the loss of voluntary muscle movement of one side of the face. A quantitative, objective, and reliable assessment system would be an invaluable tool for clinicians treating patients with this condition. This paper presents a novel framework for objective measurement of facial paralysis. The motion information in the horizontal and(More)
OBJECTIVE To examine the relationship between growth rate of vestibular schwannomas and the expression of various growth factor receptors. STUDY DESIGN Retrospective case review of clinical growth rate in conjunction with a histopathologic and immunohistochemical reexamination of archival specimens. SETTING A tertiary referral neurotologic center. (More)
Fifty-six patients with osteogenesis imperfecta underwent clinical and audiological assessment. They completed questionnaires regarding their physical and otological disabilities, and attended various centres for audiological testing. It was found that 31 patients had a hearing loss. Hearing loss began in the second and third decades as a conductive loss,(More)
This article presents a framework for the design of concept detection systems for image and video indexing. This framework integrates in a homogeneous way all the data and processing types. The semantic gap is crossed in a number of steps, each producing a small increase in the abstraction level of the handled data. All the data inside the semantic gap and(More)
OBJECTIVES To describe the use of the great auricular nerve as a 'road map' for locating the accessory nerve in the anterior and posterior triangle, in comparison with other methods described in the literature. DESIGN A review of the literature using Medline and Embase searches was performed. Illustrative photographs were taken from consenting, elective(More)
AIM Intralabyrinthine schwannomas (ILS) are rare benign tumours. They are not always recognized on routine magnetic resonance imaging (MRI). We aimed to study the clinical presentation and MRI findings in our patients with ILS. MATERIALS AND METHODS Retrospective analysis of patients with vestibular schwannomas treated at this center. RESULTS Of 144(More)
OBJECTIVE To produce a reliable objective method of assessing the House-Brackmann (H-B) and regional grades of facial palsy with the results produced and presented in a time and manner suitable for a routine clinical setting. STUDY DESIGN Analysis of video pixel data using artificial neural networks (ANNs). SETTING Tertiary-referral neuro-otologic(More)
OBJECTIVE To compare the results using a new computerised objective method of assessing the degree of facial palsy with the results obtained using traditional clinical methods. DESIGN Prospective computerised pixel change analysis and clinical evaluation of videos. SETTING Tertiary referral centre. PARTICIPANTS Subjects with varying degrees of(More)
