ENT problems occur frequently in the community, and most are managed without consulting medical services. Whilst reasonable for many problems, there are likely to be important groups in the community with ENT problems that might benefit from modern interventions.

No staging system for cholesteatoma has been universally adopted. All previous attempts failed to gain acceptance because of the lack of clinical relevance. We have devised a simple system to stage cholesteatoma which is based on the extent of lesion, ossicular condition and the preoperative complications. To illustrate the systems potential value, data from 119 new patients with cholesteatoma are presented and classified according to our proposed scheme. This shows a relationship between the stage of disease, ossicular damage and the occurrence of complications. The proposed staging system is potentially useful when considering the type of surgery required and when comparing published data reporting the results of tympanomastoid surgery.

The aim of this study was to investigate the aetiology of acquired atresia and stenosis of the external auditory meatus and to present our results for surgical management. Over an 18-year period (from 1986 to 2004), data were collected prospectively from patient cohorts in Dundee and Edinburgh. Stenosis of the auditory meatus was due to chronic otitis externa in 64 per cent of cases, compared with 37 per cent of cases with acquired atresia; the latter had instead a history of chronic suppurative otitis media in 43 per cent. Surgical treatment of canal stenosis with meatoplasty alone achieved a widely patent ear canal in 80 per cent of cases, with 78 per cent of ears remaining free of discharge. Cases of acquired atresia treated with simple surgical excision of the soft tissue plug experienced a 100 per cent failure rate. The additional use of a split skin graft achieved a patent meatus in 70 per cent of cases, with hearing improvement in 79 per cent. However, the ear canal remained unstable and late recurrence was observed.

Noise exposure, hearing loss and associated otological symptoms have been studied in a group of 23 disc jockeys using a questionnaire and pure tone audiometry. The level of noise exposure in the venues where they work has also been studied using Ametek Mk-3 audio dosimeters. Three members of the study group showed clear evidence of noise-induced hearing loss on audiometry, 70 per cent reported temporary threshold shift after sessions and 74 per cent reported tinnitus. Sound levels of up to 108 dB(A) were recorded in the nightclubs. The average level for a typical session was 96 dB(A) which is above the level at which the provision of ear protection is mandatory for employers in industry. It can be concluded that DJs are at substantial risk of developing noise-induced hearing loss and noise exposure in nightclubs frequently exceeds safe levels.
