Juvenile angiofibroma: the lessons of 20 years of modern imaging

The Journal of Laryngology & Otology (1999)

Glyn Lloyd David Howard Peter Phelps Anthony D. Cheesman

Seventy-two patients with juvenile angiofibroma have been investigated by computerized tomography (CT) and/or magnetic resonance imaging (MRI) over a period of 20 years. The evidence from these studies indicates that angiofibroma takes origin in the pterygo-palatine fossa at the aperture of the pterygoid (vidian) canal. An important extension of the tumour is posteriorly along the pterygoid canal with invasion of the cancellous bone of the pterygoid base, and greater wing of the sphenoid (60 per cent of patients). Distinctive features of angiofibroma are the high recurrence rate, and the rapidity with which many tumours recur. It is postulated that the principal determinant of recurrence is a high tumour growth rate at the time of surgery coupled with incomplete surgical excision. The inability to remove the tumour in toto is principally due to deep invasion of the sphenoid, as described above. In this series 93 per cent of recurrences occurred with this type of tumour extension. A contributory cause in these patients is the use of pre-operative embolization. The treatment implications of these findings are examined.

The UCH/RNID cochlear implant programme: Patient selection

British Journal of Audiology (1986)

J. G. Fraser Huw R. Cooper J. W. P. Hazell Peter Phelps Glyn Lloyd

After an initial postal questionnaire, patients undergo a series of tests and assessments designed to establish their suitability for implantation. The following criteria should be met: Total or profound post-lingual hearing loss. Sufficient age to give informed consent. General good health. Psychological stability. Unable to benefit from hearing aids. Free from middle ear or mastoid disease. Detailed medical, audiometric, vestibular and psychological investigations are performed, as well as acute electrical stimulation of the cochlea, and a hearing aid trial in those subjects with some measurable hearing. Fifty-two applicants have so far been assessed and of these 14 have been found to be suitable for implantation and seven have received implants.

An Inexpensive Serial Changer for Lumbar and Thoracic Aortography

British Journal of Radiology (1963)

Glyn Lloyd

An increasing demand for lumbar and thoracic aortography in the X-ray departments of the smaller hospitals has created the need for a simple and inexpensive cassette changer suitable for these procedures. Hitherto, the choice of equipment available lay between the hand-drawn variety of changer such as the Garrow and the very expensive Elema-Schonander AOT or rollfilm changers. Installation of the latter is difficult to justify in the smaller X-ray department where angiocardiography is rarely if ever performed, and where the amount of angiography generally is not very great. Our experience with a hand-drawn changer showed that despite the addition of automatic exposure devices to speed up the rate at which films could be taken, adequate renal arteriography was not always attainable. Speeds of at least three films per second are necessary to achieve satisfactory results in 100 per cent of cases and speeds faster than this are sometimes desirable. These considerations led to an examination of the possibility of designing an apparatus capable of such a performance which was mechanically simple and therefore inexpensive to produce. To keep costs to a minimum it was essential to use standard cassettes and it became immediately apparent that the mechanical problems of moving 14 × 14 in. cassettes weighing nearly 6 lb. at the speeds required are formidable if the radiographic object-film distance is to remain constant throughout the series.

The demonstration of tumours of the parapharyngeal space by magnetic resonance imaging

British Journal of Radiology (1986)

Glyn Lloyd Peter Phelps

Seven patients with parapharyngeal neck masses have been investigated by magnetic resonance imaging (MRI). These presented a wide spectrum of the tumours commonly found in this location. Magnetic resonance imaging has been shown to be superior to computed tomography in the investigation of these patients. The advantages include: better delineation of the tumour in three planes and the extent of its involvement in the head and neck, the demonstration of neck vessels without intravenous contrast, the demonstration of the vascular nature of the mass, and better soft-tissue demonstration of skull base involvement. It is concluded that CT is no longer necessary as a routine procedure for the investigation of parapharyngeal tumours when MRI is available.

Radiology of orbital masses in children.

PubMed (1986)

D. P. E. Kingsley Glyn Lloyd B. E. Kendall

Ninety-three children (103 orbital tumours) have been examined. Typical appearances were noted in one half of the cases. Most of the optic nerve gliomas, rhabdomyosarcomas, metastatic neuroblastomas and all the dermoids were typical. The most variable appearance was seen in vascular malformations which sometimes could be confused with typical lesions of other histologic type.
