The tumour masqueraded as a vestibular schwannoma on imaging but the presenting features were unusual, the facial pain and weakness predominating despite well preserved hearing. This is an example of a rare cerebellopontine angle tumour and highlights the need for(More)
Acoustic rhinometry now has an established place in the rhinology laboratory as a measure of nasal geometry. We aimed to investigate several aspects of technique in order to offer some guidance on preferred procedures. We studied the effects of nosepiece seal quality, nosepiece aperture diameter, angle of inclination of the wave tube (in two planes), palate(More)
This study aimed to assess the effects of recent controls on juniors' duty hours (the 'New Deal') on the work performed by all grades of ENT medical staff 'out of hours'. For 100 days in 1993 the out of hours duties of all grades of doctor in the Otolaryngology Unit were monitored using daily logs. Three patterns of cover were run in parallel and subjected(More)
The ability of acoustic rhinometry to detect objects of defined size in nasal cavities has hitherto been investigated only in cadavers and models. We aimed to determine the resolution of the technique in the nose of living subjects. Silicone spheres of 3.0, 5.0, and 7.0 mm diameter were placed at two sites in the decongested and locally anaesthetised nasal(More)
