Human cochleae were fixed in glutaraldehyde, without the use of osmium. Cross-links were seen between the stereocilia, similar to those we have previously reported for the guinea pig: first, stereocilia of the same row on each hair cell were joined by horizontally-running links; secondly, the shorter stereocilia had pointed tips, each giving rise to a(More)
KEYPOINTS: Tumours that arise in the thoracic inlet and superior mediastinum may be benign or malignant and present the surgeon with a difficult problem of access. The standard approach to the thoracic inlet from below offers limited exposure to the vascular and neural structures superior to the tumours. The anterior thoraco-cervical approach to the root of(More)
Nine patients who have undergone total laryngo-pharyngectomy with free jejunal reconstruction between 1984 and 1993, have had Blom-Singer valves inserted. All patients had little or no voice prior to valve insertion, compared with a good but gravelly voice after valve insertion. Tracheo-oesophageal puncture and valve insertion provides a safe and reliable(More)
The functional role of the paranasal sinuses in man has long been in dispute and as yet no satisfactory explanation has been offered for these 'unwanted' spaces. An answer may be found by study of the comparative evolutionary development of the sinuses in man and other higher primates. Several unique physical characteristics of man not seen elsewhere in the(More)
The aim of this study was to evaluate the expression of CC chemokine receptor 7 (CCR7) in squamous cell cancer of the tonsil with respect to patterns of spread, relapse-free, overall and disease-specific survival. Eighty-four patients with squamous cell cancer of the tonsil were identified. There was a male predominance of 3 : 1 and the median age at(More)
Tracheo-oesophageal puncture now has a well established role and in several units is now the principal means of speech rehabilitation following laryngectomy. Although not a difficult procedure, there are a number of problems and complications that may be encountered. With proper management these can usually be overcome and a useful voice achieved.

A clinical study was undertaken in 21 patients to assess the effects of past radiotherapy on complications after tongue resection with the CO2 laser. Ten of the 11 irradiated patients experienced postoperative problems such as pain, haemorrhage, oedema, infection, delayed healing and poor function, while only one of the 10 non-irradiated patients had a(More)
